  • Food insecurity around the U.S. has risen this year, survey finds

    The share of Americans reporting trouble affording food is rising this year amid persistently high grocery costs, according to a recent report from Purdue University.

    Roughly 14% of U.S. households reported food insecurity on average between January and October, up from 12.5% in 2024, according to the latest data from Purdue’s Center for Food Demand Analysis and Sustainability.

    While the prevalence of food insecurity around the U.S. fluctuates month to month, the overall rate had been declining since 2022, when an average of 15.4% of households were food insecure as inflation hit 40-year highs following the pandemic. 

    Although the pace of inflation has declined since 2022, food insecurity is likely rising because food prices remain far above pre-pandemic levels, according to Poonam Gupta, a research associate at the Urban Institute, a think tank in Washington, D.C.

    “Even though inflation slowed a lot this year, we’re nowhere near the amount that we were spending on food even just a couple of years ago,” she said.

    Gupta also said more Americans could struggle to put food on the table in 2026, with an estimated 2.4 million SNAP recipients potentially losing benefits due to new work requirements in the Republican-backed “big, beautiful” tax and spending bill signed into law in July by President Trump. 

    The Purdue researchers define food insecurity as some members of a household at times not being able to afford a balanced meal, as well as occasionally having to skip a meal or eating less for financial reasons. 

    Purdue’s survey has become one of the few remaining national measures of food insecurity, since the U.S. Department of Agriculture canceled its annual Household Food Security survey in September, which had been conducted since 2001.

    In scrapping the USDA assessment of food insecurity, the Trump administration said in September that the survey was “redundant, costly, politicized and extraneous.”

    But researchers told CBS News that the government data was widely respected. Craig Gundersen, a Baylor University economics professor who has studied food insecurity for 30 years, called the USDA survey the “gold standard measure.” 

    Joseph Balagtas, director of Purdue’s Center for Food Demand Analysis, said the school surveys about 1,200 adults a month, compared to 30,000 people surveyed yearly by the USDA. 

    Even so, he said, Purdue’s findings have generally mirrored federal food security data because participants are asked identical questions and because they use statistical methods to ensure their data is representative of the general population.

  • Amelia Earhart’s long-lost plane likely located in lagoon, expedition team claims, citing “very strong” evidence

    Researchers from Purdue University are set to travel to the South Pacific to determine if a “visual anomaly” on a remote island is the wreck of Amelia Earhart’s lost plane, saying there is “very strong” evidence the object is the iconic aviator’s aircraft. 

    Earhart was attempting to become the first female pilot to circle the world when she and navigator Fred Noonan disappeared over the Pacific Ocean on July 2, 1937. Earhart, Noonan and their plane, an Electra 10E, were never found. Recently, President Trump ordered records related to Earhart be declassified. 

    In 2020, researchers looking at satellite imagery identified a “visual anomaly” known as the Taraia Object in a lagoon on Nikumaroro, a small island in Kiribati about halfway between Australia and Hawaii, according to a news release from Purdue University. Nikumaroro is about 400 miles southeast of Howland Island, Earhart and Noonan’s planned destination. 

    The underwater object has been visible in photos dating back to 1938, the year after Earhart and Noonan disappeared

    A team of researchers from Purdue University, the Purdue Research Foundation and the Archaeological Legacy Institute will travel to Nikumaroro to inspect the object in November. The team will first take photos and videos of the site, then use magnetometers and sonar devices to scan the area. Then, the item will be dredged and lifted from the water so researchers can attempt to identify it. 

    Theories have abounded about Earhart and Noonan’s fates since their disappearance. One theory suggests that Earhart landed on Nikumaroro and was marooned on the island before her death. The International Group for Historic Aircraft Recovery, a nonprofit organization based in Pennsylvania, has collected evidence it says supports the theory. Richard Pettigrew, the executive director of the Archaeological Legacy Institute, said that the expedition offers a chance to find “smoking-gun proof” that confirms the theory. 

    ”We gathered up many more satellite images, did historical research, found other imagery that relates to it,” Pettrigrew said. “We’re going to go look and identify it. And if we’re right, we’ll in fact identify the lost Electra. We could be wrong but I think the evidence is very, very strong that this is, in fact what it is.”

    However, Ric Gillespie, executive director of the International Group for Historic Aircraft Recovery, has expressed skepticism. “We’ve looked there in that spot, and there’s nothing there,” he told NBC News in July.

    Steve Schultz, a Purdue senior vice president and the university’s general counsel, will be a field assistant on the expedition. He said that if the object is identified as Earhart’s plane, the university hopes it can transport the plane home. Earhart worked at Purdue University for two years in the 1930s, and the Purdue Research Foundation originally paid for the airplane that Earhart flew, the school said. She planned to return the craft to the university after her trip around the world. 

    “A successful identification would be the first step toward fulfilling Amelia’s original plan to return the Electra to West Lafayette after her historic flight,” Schultz said in the news release. 

    Last year, an expedition team captured a sonar image in the Pacific Ocean that appeared to resemble Earhart’s plane resting at the bottom of the sea. It turned out  to be a rock formation.

  • March Madness: Northwestern, Illinois among men’s basketball teams seeded in NCAA Tournament

    March Madness: Northwestern, Illinois among men’s basketball teams seeded in NCAA Tournament

    CHICAGO (WLS) — Northwestern University and the University of Illinois were among the teams Sunday who were selected and seeded for the March Madness college basketball tournament.

    Northwestern will be a No. 9 seed in the east region, playing No. 8 seed Florida Atlantic on Friday in Brooklyn, New York. Illinois will be a No. 3 seed in the east region, facing Moorhead State in a first-round game Thursday in Omaha, Nebraska.

    Most Northwestern Wildcats fans celebrating the announcement Sunday night at Welsh-Ryan Arena in Evanston said they were expecting to get in, and they can’t wait to keep cheering the team on.

    Just to see us in the dance for the second year in a row is incredible

    Will Klearman, Wildcats fan

    The Northwestern men’s basketball team is going dancing. For the first time in school history, the men’s team has clinched back-to-back NCAA Tournament appearances.

    The Northwestern men’s basketball team is going dancing. For the first time in school history, the team has clinched back-to-back NCAA Tournament appearances.

    Fans of all ages packed Welsh-Ryan Arena to take in the moment with the team.

    “I mean it’s incredible… it’s a blessing,” Northwestern fan Will Klearman said. “I’ve been coming to these games since I was four years old, and just to see us in the dance for the second year in a row is incredible.”

    Fans at the watch party didn’t have to wait long for the celebration as Northwestern’s matchup was quickly announced as the second matchup to open the selection show.

    “Very quick… not much time before the confetti started to fall, which was great,” Northwestern fan Elliot Kadar said.

    Some fans were never worried.

    “We knew we were making it,” Northwestern fan Yosef Bolkowitz said. “There was no sweating.”

    It has been a special year for the Wildcats, with the team upsetting some of the top teams in the nation during the regular season.

    Members of the team took time to sign autographs for kids after the announcement. The community continues to rally around the school.

    “It’s a great experience,” team equipment manager Jaren McGee said. “Northwestern back-to-back years in the NCAA Tournament… never happened before, so we’re happy to do this and bring our fans out, and experience this as well. It’s been great.”

    Fans know a tough road is ahead as the reigning national champs at UConn are in their region, but there’s no shortage of confidence as March Madness begins.

    “I’m happy. Go cats!” Northwestern fan Jayden Wharton said. “It’s our year, we’re winning the natty. Let’s go!”

    Defending champion Connecticut, along with Houston, Purdue and North Carolina, are the top seeds in a March Madness bracket that started going haywire even before the pairings came.

    Of the four top seeds, only UConn heads into the tournament coming off a win. That played into the Huskies receiving the No. 1 overall seed. The other three top seeds lost in their conference tournaments.

  • Consumers face perplexity with food-date labels, causing confusion in decision-making.

    Consumers face perplexity with food-date labels, causing confusion in decision-making.

    Consumers grapple with confusion over food-date labels

    Newswise — The use of food-date labels such as “use-by” and “best if used by” causes consumer confusion that results in many Americans discarding food that is safe to eat or donate, according to the November 2023 Consumer Food Insights Report.

    The survey-based report out of Purdue University’s Center for Food Demand Analysis and Sustainability assesses food spending, consumer satisfaction and values, support of agricultural and food policies and trust in information sources. Purdue experts conducted and evaluated the survey, which included 1,200 consumers across the U.S. 

    The Congressional Research Service recently reported that 7% of all U.S. food waste is because of date labeling confusion. “The goal of this month’s CFI survey was to gather consumer perceptions about what these food date labels mean,” said the report’s lead author, Joseph Balagtas, professor of agricultural economics at Purdue and director of CFDAS.

    The USDA Food Safety and Inspection Service defines “use-by” and “best if used by” as references to peak food quality rather than the date after which the food is no longer safe to eat. However, there is no official standard for food date labeling in the U.S., which leads to an unsurprising mix of responses as to what they mean.

    “Over half of consumers connect “best if used by” and “use-by” dates with food safety, while over 30% believe these labels are related to food quality,” Balagtas said. “This information problem is a kind of market failure and leads to waste.

    “One potential fix to misinformation is for the government to set standards for food date labels to help inform consumers what is and is not safe to eat to help reduce food waste in the U.S. The recently proposed Food Date Labeling Act is an attempt to achieve that goal.”

    The November survey also looked at consumer perceptions of foodborne illness risks. Food-risk attitudes are divided into three groups: risk-averse, risk-neutral and risk-loving. The groupings were based on respondents’ self-assessed risk tolerance for food at home (FAH) and food away from home (FAFH) on a scale from 0 (risk-averse) to 10 (fully prepared to take risks or risk-loving). The summaries broken down this way focus on CFI data from January to November 2023.

    “We found that consumers believe the risk of contracting a foodborne illness is higher when eating food at a restaurant compared to eating food they prepare at home themselves, which is consistent with data on the incidence of foodborne illness,” Balagtas said. “So it is not surprising that we also see that consumers who are more risk-averse when it comes to their food, eat home-cooked meals more frequently than consumers willing to take more risks with their food consumption.”

    A variety of store-bought goods have the potential to contain foodborne bacteria that cause illness. Even so, consumers were more likely to select raw meat items as foods that pose a high risk of foodborne illnesses.

    “We see a gap of more than 20 percentage points in the rate at which raw meats were selected compared to leafy greens, milk, flour and raw fruits and vegetables, despite the fact that some of these items that are perceived as ‘safer’ have caused foodborne illness outbreaks in the past,” Balagtas noted.

    The Interagency Food Safety Analytics Collaboration, a group tasked with monitoring the causes of foodborne illnesses in the U.S., recently reported that the contribution of fresh produce to foodborne outbreaks is comparable to that of raw meats, and in some cases, greater.

    The November survey also showed that food insecurity has dropped slightly for the fifth straight month, to 12.6%. “We do observe higher rates of food insecurity among risk-loving consumers, though this difference is likely the result of the correlation between age and food risk attitudes,” said Elijah Bryant, a survey research analyst at the center and co-author of the report.

    Generally, older consumers with more resources, on average, tend to be more food secure and less willing to take food risks, while younger people more willing to take risks tend to have fewer resources, resulting in higher rates of food insecurity.”

    Consumers also were asked to recall their food behaviors over the last month. “Those who are classified as risk-loving reported eating fruits and vegetables without washing them, eating rare or undercooked meat and eating raw dough or batter more frequently than those who are risk-averse,” Bryant said.

    Consumers less willing to take risks with their food were also less likely to agree with claims about the health benefits of non-conventional food items. These claims include organic being more nutritious than non-organic, plant-based milk is healthier than dairy milk and gluten-free food is healthier than products containing gluten.

    This may be indicative of risk-averse consumers being more resistant to alternative foods in the food system that stray from what they perceive as the norm, Bryant said.

    The Center for Food Demand Analysis and Sustainability is part of Purdue’s Next Moves in agriculture and food systems and uses innovative data analysis shared through user-friendly platforms to improve the food system. In addition to the Consumer Food Insights Report, the center offers a portfolio of online dashboards.

  • Scientist Invents the ‘World’s Whitest Paint’ To Cool Down Your House | Entrepreneur

    Scientist Invents the ‘World’s Whitest Paint’ To Cool Down Your House | Entrepreneur

    A scientist at Purdue University concocted a white paint that can cool down buildings and prevent global temperatures from rising.

    Xiulin Ruan, a professor of mechanical engineering, created white paint that reflects 98% of the sun’s rays away from the Earth’s surface. When applied to the roof of structures, the paint cools down surfaces as much as eight degrees during the day and up to 19 degrees cooler at night, according to a report in The New York Times.

    “If you were to use this paint to cover a roof area of about 1,000 square feet [93 m2], we estimate that you could get a cooling power up to 10 kilowatts. That’s more powerful than the air conditioners used by most houses,” Ruan said.

    Scientists consider paints like this transformational for cooling down the planet and reducing electricity use, as buildings with this kind of white paint would require less air conditioning.

    And Ruan doesn’t want to stop at buildings. Last year, he announced that he has invented a version of this paint for vehicles, too.

    World record holder

    How white is the paint? In 2021, the Guinness Book of World Records named it the whitest paint on earth. But Ruan Ruan told the Times that wasn’t the goal.

    “We weren’t really trying to develop the world’s whitest paint,” Dr. Ruan said. “We wanted to help with climate change, and now it’s more of a crisis and getting worse. We wanted to see if it was possible to help save energy while cooling down the Earth.”

    Unfortunately, the paint won’t be on sale for about another year, as researchers are working on improving its durability and resistance to dirt.

    But with the planet recording record temperatures almost daily, the need for a global paint job couldn’t come fast enough.

  • Biotech restores at-risk forest trees holistically

    Biotech restores at-risk forest trees holistically

    BYLINE: Steve Koppes

    Newswise — WEST LAFAYETTE, Ind. – Many at-risk forest tree species will probably need biotechnology along with traditional tree-breeding approaches to survive, according to insights published in the July issue of the journal New Forests.

    Purdue University’s Douglass Jacobs and Kasten Dumroese of the U.S. Forest Service led a team of 19 co-authors, including scientists, land managers and regulators, in presenting their findings on biotechnological risk assessment and forest tree restoration. Their New Forests paper, published in a special issue on threatened tree species, presents key outcomes of a 2021 virtual international conference on the issues. 

    Among their conclusions: Society drives policy. If genetic engineering is the only way to save some species, its use will require public acceptance.

    “Biotechnology is a diverse toolkit comprising different technologies that can be used to impart pest resistance – it could be bugs or pathogens – in our threatened forest trees,” said Jacobs, the Fred M. van Eck Professor of Forest Biology. But many people mistakenly equate biotechnology with genetic engineering. 

    “Traditional tree breeding, whether you’re breeding different species or different varieties within species, has been going on for thousands of years. And the regulations on planting trees that have been traditionally bred are wide open,” he said. “Genetic engineering, on the other hand, is highly regulated, but all biotechnology is certainly not genetic engineering.”

    Scientists often use genomics, for example, which involves working with the complete set of an organism’s genetic material, to learn more about what causes disease. Genomics also can help identify the genes responsible for useful traits such as pest resistance.

    Blight began afflicting the American chestnut in the 1900s, killing billions of trees. Despite being the target of decades-long tree-breeding efforts, the chestnut’s prospects remain in doubt. The list of at-risk species also includes ash, butternut, and bristlecone pine among other members of the five-needle white pine family. 

    “I feel a sense of urgency. We can’t take a hundred years like we’ve taken with chestnut to turn the page,” said Dumroese, a research plant physiologist at the Forest Service’s Rocky Mountain Research Station in Idaho.

    “The species are becoming ecologically extinct,” Dumroese said. “They’re not able to provide their historic level of ecosystem function because often they don’t grow to maturity. And that’s happening at a faster and faster pace. Look at how rapidly we’ve lost ash trees from our forests and urban landscapes because of the introduced insect pest emerald ash borer.”

    The western white pine is an example of how the Forest Service has, starting in the 1960s, effectively used traditional tree breeding to cope with white pine blister rust. The white pine population remains below its pre-blister-rust levels, however, and may never become fully restored.

    “But we see a lot more western white pine on the landscape and being planted on the landscape every year because of those efforts,” Dumroese said. “That process only took a couple of decades where we come from a big problem to making improvements. We need that pace for all of the species that we’re calling at risk.”

    Back in Indiana, the Hardwood Tree Improvement & Regeneration Center, a joint effort between Purdue and the Forest Service, for years has maintained a breeding program for pest resistance. Almost all of the center’s efforts to date have focused on traditional tree breeding and genomics. 

    “The chance to work with chestnut and help reintroduce it back to the landscape was a big reason I took the Purdue job in the first place back in December of 2001,” Jacobs said. “Watching species disappear from the landscape provides me personally with a lot of motivation to contribute whatever I can toward helping to save some of these at-risk species.”

    In the last 10 years, Jacobs has seen striking advancements in novel biotechnologies that use genomics and genetic engineering.

    “For some species, traditional tree breeding doesn’t appear to be a viable long-term option to get disease-resistant trees. In those cases, it’s probably going to have to be genetic engineering if we want to save the species,” he said.

    That applies even to a species like the blight-afflicted American chestnut, the target of a breeding program for 50 years. “Introducng enough chestnut and ash trees to bring us back to the pre-disturbance level is likely not possible in anyone’s lifetime, but you have to start somewhere,” Dumroese noted.

    The participants of the 2021 conference came to a consensus on the applicability of biotechnology toward reintroducing some threatened forest tree species. They came from academia, the Forest Service, and organizations such as the American Chestnut Foundation and the Nature Conservancy.

    “Societal perception and policy remain the weakest links,” Jacobs said. “There’s been this consistent one-way flow of information from scientists to the public with the idea of, ‘Hey, we’re scientists, trust us.’ Or ‘We’re the government, trust us.’ But you need a much more interactive dialogue to be successful in changing public opinion.”

    Support for the conference and related work was provided by the U.S. Department of Agriculture Forest Service and National Institute of Food and Agriculture.

  • Lack of canine COVID-19 data fuels persisting concerns over dog-human interactions

    Lack of canine COVID-19 data fuels persisting concerns over dog-human interactions

    Newswise — WEST LAFAYETTE, Ind. — Early COVID-19 pandemic suspicions about dogs’ resistance to the disease have given way to a long-haul clinical data gap as new variants of the virus have emerged.

    “It is not confirmed that the virus can be transmitted from one dog to another dog or from dogs to humans,” said veterinarian Mohamed Kamel, a postdoctoral fellow at Purdue University.

    During the pandemic’s early days, dogs seemed resistant to the coronavirus, showing little evidence of infection or transmission, said Mohit Verma, assistant professor of agricultural and biological engineering and Purdue’s Weldon School of Biomedical Engineering. “As the virus evolved, or maybe the surveillance technology advanced, there seem to be more instances of potentially asymptomatic dogs.”

    These are among the findings that Kamel, Verma and two co-authors summarized in a research literature review “Interactions Between Humans and Dogs in the COVID-19 Pandemic.” The summary, with recent updates and future perspectives, recently appeared in a special issue of the journal Animals on Susceptibility of Animals to SARS-CoV-2.

    Additional co-authors are Rachel Munds, a research scientist at Krishi Inc. and a Purdue visiting scholar in the Department of Agricultural and Biological Engineering, and Amr El-Sayed of Egypt’s Cairo University.

    Last June the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service announced it was committing up to $24 million for research related to SARS-CoV-2. The funding, provided by the American Rescue Plan Act, focuses on the One Health concept, which recognizes the link between the health of people, animals and the environment.

    The SARS-CoV-2 virus that originated in Wuhan, China, in 2019 has infected more than 600 million people globally and had claimed more than 6.5 million lives by October 2022.

    “COVID-19 has become one of the most important economic, health and humanitarian problems of the 21st century,” the co-authors wrote in the Animals article. Studies have documented the movement of the SARS-CoV-2 virus through various animal species. And about 75 percent of infectious diseases in humans start in animals.

    “This spread raises concerns about the possibility of pet animals serving as reservoirs for the virus,” the co-authors wrote.

    More than two dozen animal species have been infected by SARS-CoV-2 virus, ranging from cats, dogs and rabbits to deer, cattle and gorillas. More than 470 million dogs were owned worldwide before the COVID-19 outbreak. Their susceptibility to the virus remains poorly understood because they are infrequently tested, said Kamel, who is also a faculty member at Cairo University.

    “Compared to cats or other animals, the susceptibility is less,” Kamel said. He cautioned, however, that the susceptibility of dogs to the new variants may have changed to a lesser or greater extent.

    “There are a lot of variants. It’s not only one virus,” Kamel said. “The infections differ from the old variant to the new variant.”

    Dogs’ apparent resistance to COVID-19 could result from their general low levels of the angiotensin converting enzyme (ACE2), target receptors in their lung cells and related mutations.

    “ACE2 is the main part of the virus attachment found on the cells,” Kamel noted.

    The Animals journal article also discusses how the spread of an epidemic can be tracked, predicted and contained through a combination of geographic information systems, molecular biology and even detection dogs. Because of their heightened sense of smell, dogs can be trained to detect a wide range of human diseases, Kamel said. Using dogs to detect COVID-19, as reported in the journal article, is fast and less expensive compared to other methods where screening large crowds may be needed.

    Verma’s startup, Krishi Inc., is already developing innovative paper-based, rapid-result tests for bovine respiratory disease, antimicrobial resistance and COVID-19. The testing system uses a method called loop-mediated isothermal amplification (LAMP) and is under development in Verma’s lab for produce safety applications. Adapting LAMP for animal testing of SARS-CoV-2 may come next.

    Krishi Inc. received an initial investment from Ag-Celerator. Created in 2015, Ag-Celerator is a $2 million innovation fund designed to provide critical startup support for Purdue innovators who bring Purdue’s patented intellectual property or “know-how” technologies to market. The fund is operated by Purdue Ventures with assistance from the Purdue University College of Agriculture, the Purdue Research Foundation Office of Technology Commercialization and the agriculture industry.

    The Animals journal article cites multiple studies from Purdue and elsewhere validating the usefulness of LAMP testing. Krishi’s focus thus far has been developing a test for antimicrobial resistance in animals, but the LAMP assay has broader potential, Verma said.

    “If we want to do widespread surveillance, can we make our test versatile for any species? LAMP is portable,” Verma said. “Because it can be done in a simple manner and provide results without a lab setup, we can potentially do this on a wider scale and make it cost-effective.”

    Currently available commercial at-home coronavirus tests for humans can also be used on dogs and cats. However, these tests may not be sensitive enough to detect the lower viral loads in animals.

    “They’re not validated for animals, so we don’t know how well they would work. That’s the gap we’re hoping to bridge with the test that we are developing – better tools of surveillance,” Verma said.

    No. 16 seed Fairleigh Dickinson shocks Purdue in NCAA Tournament

    Unpacking upsets in March Madness so far


    Major upsets highlight first day of NCAA men’s basketball tournament

    04:20

    Fairleigh Dickinson became the second No. 16 seed in history to win an NCAA Tournament game, stunning top-seeded Purdue 63-58 behind 19 points from Sean Moore and a relentless, hustling defense on Friday night.

    The shortest team in the tourney, the Knights (21-15) showed no fear in swarming 7-foot-4 All-America center Zach Edey from the start. FDU’s players were quicker and more composed than the Big Ten champion Boilermakers (29-6).

    Five years ago, UMBC showed the way for the little guys by overwhelming Virginia in the first 16-over-1 victory after numerous close calls over the years. Still, No. 16s had a 1-150 record before FDU’s shocker.

    Fairleigh Dickinson didn’t even win the Northeast Conference Tournament, falling by one point in the title game to Merrimack, which couldn’t participate in the NCAA Tournament because of an NCAA rule that bars it from the postseason because it’s still completing its four-year transition from Division II.

    “The more I watch Purdue, the more I think we can beat them,” Fairleigh Dickinson head coach Tobin Anderson told his team on Wednesday night after defeating Texas Southern 84-61 in the First Four to earn the matchup with Purdue.

    FDU held Purdue scoreless for more than 5 1/2 minutes down the stretch and moved ahead by five on a 3-pointer by Moore with 1:03 left. The Knights held on from there, becoming the second straight double-digit seed to send the Boilermakers home. Purdue was a 3 seed when it lost to 15 seed Saint Peter’s in the Sweet 16 last year.

    ESPN also noted that the Fairleigh Dickinson win meant that of the approximately 20 million brackets filled out for its annual Tournament Challenge, zero perfect brackets remained in play.

  • Proposed quantum device may succinctly realize emergent particles such as the Fibonacci anyon

    Proposed quantum device may succinctly realize emergent particles such as the Fibonacci anyon

    Newswise — Long before Dr. Jukka Vayrynen was an assistant professor at the Purdue Department of Physics and Astronomy, he was a post-doc investigating a theoretical model with emergent particles in a condensed matter setting. Once he arrived at Purdue, he intended to expand on the model, expecting it to be relatively easy. He gave the seemingly straightforward calculations to Guangjie Li, a graduate student working with Vayrynen, but the calculations yielded an unexpected result.  These results were a surprising roadblock which nearly brought their research to a screeching halt.  Team tenacity has taken this roadblock and turned it into a possible route to the development of quantum computing.

    At the Aspen Center for Physics in Colorado, Vayrynen discussed this issue with a colleague from the Weizmann Institute of Science in Israel, Dr. Yuval Oreg, who helped circumvent the obstacle. The team used this new understanding of their calculations to propose a quantum device that could be tested experimentally to succinctly realize emergent particles such as the Fibonacci anyon. They have published their findings, “Multichannel topological Kondo effect,” in Physical Review Letters on February 10, 2023.

    Condensed matter theory is a field of physics that studies, for example, the properties of electronic quantum systems, with applications to technologies such as superconductors, transistors, or quantum computing devices. One of the challenges in this field is understanding the quantum mechanical behavior of many electrons, also known as the “many-body problem.” It is a problem because it can only be theoretically modeled in very limited cases. However, even in those limited cases, rich emergent phenomena such as collective excitations or fractionally charged emergent “quasi”-particles are known to emerge. These phenomena are a result of the complex interactions between electrons and can lead to the development of new materials and technologies.

    “In our paper, we propose a quantum device that is simple enough to be theoretically modeled and tested experimentally in the future, yet also complex enough to display non-trivial emergent particles,” says Vayrynen. “Our results indicate that the proposed device can realize an emergent particle called a Fibonacci anyon that can be used as a building block of a quantum computer. The device is therefore a promising candidate for the development of quantum computing technology.”

    This discovery could be used in future quantum computers in a way that allows one to make them more resistant to decoherence, a.k.a. noise.

    According to their publication, the team introduced a physically motivated N-channel generalization of a topological Kondo model.  Starting from the simplest case N = 2, they conjecture a stable intermediate coupling fixed point and evaluate the resulting low-temperature impurity entropy. The impurity entropy indicates that an emergent Fibonacci anyon can be realized in the N = 2 model. 

    According to Li, “a Fibonacci anyon is an emergent particle with the property that as you add more particles to the system, the number of quantum states grows like the Fibonacci sequence, 1, 2, 3, 5, 8, etc. In our system, a small quantum device is connected to conduction electron leads which will overly screen the device and can result in an emergent Fibonacci anyon.”

    The team also gives a number of predictions that could be experimentally tested in future quantum devices.

     “We evaluate the zero-temperature impurity entropy and conductance to obtain experimentally observable signatures of our results. In the large-N limit we evaluate the full cross over function describing the temperature-dependent conductance,” says Vayrynen.

    This research is the first in a series that the Purdue team of Li and Vayrynen will work on. They collaborated with a senior scientist from Max Planck Institute for Solid State Research in Germany, Dr. Elio König, and posted a related work, “Topological Symplectic Kondo Effect,” in a preprint arXiv (2210.16614) on October 20, 2022.

    This research was based on work supported by the Quantum Science Center, a U.S. Department of Energy National Quantum Information Science Research Center headquartered at DOE’s Oak Ridge National Laboratory. Dr. Yong Chen, the Karl Lark-Horovitz Professor of Physics and Astronomy and Professor of Electrical and Computer Engineering, is on the QSC’s Governance Advisory Board, and Purdue is one of the center’s core partners.

  • A new way to identify stresses in complex fluids

    A new way to identify stresses in complex fluids

    Newswise — Fluid dynamics researchers use many techniques to study turbulent flows like ocean currents, or the swirling atmosphere of other planets. Arezoo Adrekani’s team has discovered that a mathematical construct used in these fields provides valuable information about stress in complex flow geometries.

    Ardekani, a Purdue University professor of mechanical engineering, studies complex flows: from the transport processes related to biopharmaceuticals, to the behavior of microorganisms around an oil spill. “Newtonian fluids like water are simple to understand, because they have no microstructure,” she said. “But complex fluids have macromolecules that stretch and relax, and that changes many properties of the fluid, leading to very exciting fluid dynamics.”

    Viscoelastic flows occur frequently in nature, in biomedical settings, and in industrial applications – such as solutions used in groundwater remediation. “When groundwater becomes contaminated, remediators use certain polymer-based solutions to disperse chemicals designed to break down the contaminants,” Ardekani said. “But what type of polymer should they use, how much, and where should they inject it? The only way to answer those questions is by understanding the behavior of these flows, which comes down to measuring stresses.”

    Currently, the only way to quantify the stresses of polymeric fluids is a technique called birefringence, which measure specific optical properties of the fluid. But it’s very difficult to perform, often inaccurate, and doesn’t apply to all types of macromolecules.

    Ardekani’s team has discovered a new technique. The researchers created a mathematical framework that takes input from flow velocity, obtained from particle image velocimetry (a common technique in fluid dynamics), and outputs stress and stretching field topologies for complex fluids. Their research has been featured in Proceedings of the National Academy of Sciences (PNAS).

    In particle image velocimetry (PIV), tracer particles are injected into a fluid. By using the movement of those particles, researchers can extrapolate information about the overall flow kinematics. While this can be readily used to evaluate stress in Newtonian fluids, Ardekani’s team has discovered a mathematical correlation between these measurements and the stresses in viscoelastic flows.

    It all connects through something called Lagrangian coherent structures (LCSs). “Lagrangian coherent structures are mathematical constructs used to predict the dynamics of fluid flows,” Ardekani said. “They are used by oceanographers to predict how currents will move; biologists who are tracking microorganisms; and even astrophysicists, who are observing the turbulent clouds on places like Jupiter.”

    While LCSs are often used by turbulence researchers, they have never been applied to polymeric stress until now. “We have united two disparate branches of continuum mechanics,” Ardekani said. “Using Lagrangian stretching, and applying it to Eulerian stress fields. And this applies to a wide range of scales, from the mesoscale all the way up to industry scale measurements.”

    The paper is a collaboration between Ardekani, her PhD student Manish Kumar and Jeffrey Guasto, Associate Professor of Mechanical Engineering at Tufts University. They presented their findings in November at the 75th Annual Meeting of the APS (American Physical Society) Division of Fluid Dynamics in Indianapolis, which Ardekani co-organized.

    While the research is largely mathematical, Ardekani is excited to see how experimentalists will use the technique in the lab and in the real world. “Let’s use our groundwater remediation example again,” Ardekani said. “Researchers typically use tracer analysis on the injected fluids to measure the velocity field. But now, they can also identify the stress fields, so they can more accurately predict the transport of that fluid.”

  • New Pill Treats Diabetic Cats Without Daily Insulin Shots

    New Pill Treats Diabetic Cats Without Daily Insulin Shots

    When Mark Winternheimer’s 12-year-old tabby cat was diagnosed with diabetes last year, the treatment was daunting: twice-daily injections of insulin, an implanted monitor and frequent visits to the vet.

    Despite their qualms, Winternheimer and his wife, Courtnee, of New Albany, Indiana, learned to give Oliver his shots.

    “For us, they’re part of the family,” Winternheimer said of Oliver and their two other cats, Ella and Theo. “You wouldn’t deny another family member care if it’s available.”

    Now, a new, once-daily pill promises to make treating feline diabetes easier in newly diagnosed animals, without the shots.

    “A pill is a huge step forward from a needle,” said Dr. Audrey Cook, a cat veterinarian at Texas A&M University.

    One caveat: The pill called Bexacat can’t be used in cats like Oliver, who had previously received insulin.

    The biggest benefit may be the ease of use, experts said. While many cat owners successfully treat their cats with twice-daily insulin, often for years, others struggle. Research shows that owners put down 1 in 10 cats with a new diabetes diagnosis. Another 10% are euthanized within a year, in part because of the difficulties of treatment.

    “Some people are afraid of giving insulin injections. Some people don’t have the time to dedicate to the care of their cats,” said Dr. Catharine Scott-Moncrieff, a Purdue University veterinarian who consulted with the makers of Bexacat on the product testing.

    Made by Elanco Animal Health Inc., Bexacat was approved by the Food and Drug Administration in December and is expected to be available in the U.S. in the next several weeks. It’s the first drug of its type approved for animals; similar drugs have been approved for people for about a decade.

    Diabetes, whether in people or pets, is caused when too much glucose, or sugar, builds up in the bloodstream because the pancreas doesn’t produce enough insulin, a hormone, or use it properly. Bexacat lowers blood sugar by causing it to be excreted in urine. Symptoms of feline diabetes include increased thirst and urination, increased appetite and weight loss.

    About a quarter of U.S. households include one or more cats, totaling more than 58 million felines. Between 1 in 100 and 1 in 500 cats in the U.S. are diagnosed with diabetes, which is rising as obesity rates in the species approach 50%, said Dr. Bruce Kornreich, director of the Cornell Feline Health Center at Cornell University.

    In studies involving more than 300 diabetic cats, Bexacat improved glucose control and decreased at least one symptom of diabetes in more than 80% of newly diagnosed, healthy animals, company documents show. But several cats in the studies also died or had to be euthanized after taking the drug, prompting a so-called black box warning about possible side effects, including diabetic ketoacidosis, a life-threatening complication.

    Because of those concerns, the drug can’t be used in cats previously treated with insulin and animals must be carefully screened for liver, kidney and pancreatic disease and to ensure that they’re otherwise healthy, said Scott-Moncrieff.

    “It will be life-changing for some cats and some owners, but it’s not for every cat,” Scott-Moncrieff said.

    The list price for the drug is about $53 a month, according to Elanco. Most vets will double or triple the cost of the drug, charging pet owners about $100 to $150 a month, said Cook.

    Depending on the source, that may be higher than the costs for insulin and the syringes or pens to give it, she said. Cats taking insulin need to be monitored frequently, but cats taking Bexacat will need to be watched, too.

    “I think costs will be broadly similar, but there are a lot of variables here,” Cook said.

    In Oliver’s case, the cat tolerated the injections ― and a glucose monitor that had to be inserted underneath his skin, Winternheimer said. His owners did OK, too, but they were relieved when Oliver’s diabetes went into remission last fall.

    No question, the idea of giving Oliver a pill instead would have been appealing, Winternheimer said. “I would have definitely preferred that if it were available.”

  • How Mitch Daniels Made Purdue a University Conservatives Can Love

    How Mitch Daniels Made Purdue a University Conservatives Can Love

    College is a high-priced liberal indoctrination program where radical professors and administrators quash the speech of conservatives and promote outlandish ideas like critical race theory. Meanwhile, students rack up six-figure debts to get degrees in esoteric subjects with no job prospects — a waste of time and tax dollars.

    The conservative bill of indictment against higher education is longstanding and, according to public-opinion surveys, gaining in adherents.

    But there’s one man many conservative critics of higher ed have learned to love: Mitchell E. Daniels Jr., who led Purdue University for a decade, stepping down as president at the end of last year. They laud his focus on freezing tuition and providing affordable degrees in valuable STEM subjects, as well as his decision to adopt a campus-speech policy that encourages “free, robust, and uninhibited debate and deliberation among all members of the University’s community.”

    “As a general matter, if more universities operated the way Purdue has operated, satisfaction would be much higher,” said Lindsay Burke, director of the Center for Education Policy at the conservative Heritage Foundation.

    At a moment when higher education is under constant fire from partisan detractors and the college degree has itself become a central dividing line in American politics, is Daniels’s tenure at Purdue a model for how to effectively lead a public university through fraught times? And is Daniels, a former Republican governor of Indiana, an antidote to growing conservative disfavor of higher education?

    Sitting in his office wearing a Purdue-themed, plaid button-down, Daniels insisted that he had eschewed partisan political activity while leading Purdue, and that his intent had never been to prescribe policies to other institutions. “I never used the ‘C’ or ‘L’ word, almost never the ‘R’ or ‘D’ word,” he said during an interview in early December at Purdue’s main administrative building, “but, you know, I was always trying to emphasize bringing people together.”

    That’s not to say he would mind if other universities followed his model. “Could Purdue serve as some sort of a corrective or a counterexample? I’d be very proud if that happened,” Daniels said. “I’m a big believer in higher education and its importance to the country and the importance that we maintain the best network of institutions in the world. And that’s exactly why I think its shortcomings are worth worrying about trying to improve.”

    He changed Purdue, but I’m not convinced he changed the university presidency as a job.

    Even his critics acknowledge that Daniels has been a significant president — his name is often mentioned alongside reformers like Michael Crow at Arizona State University. But they also point out that what works for a major research university wouldn’t work at most other colleges, which have more limited resources. On Purdue’s West Lafayette campus, Daniels is not immune from criticism. He is accused of shortchanging faculty pay and benefits to freeze tuition and allowing hate speech to flourish in the name of free expression. Some of Daniels’s efforts to make the university more entrepreneurial have also fallen short.

    “He’s a former governor, he knows how to get things done,” said Barrett Taylor, an associate professor of higher education at the University of North Texas. “He changed Purdue, but I’m not convinced he changed the university presidency as a job.”

    Conservatives have long held suspicions about the role and value of higher education, but its emergence as a national wedge issue has intensified since the 2016 presidential election, in particular over how colleges have sought to diversify their student bodies.

    Polls show deep and growing discontent about college among conservatives across the country. In 2019, the Pew Research Center found that nearly 60 percent of those who identified as Republican thought colleges had a negative effect on the nation. By 2021 that figure had increased to 64 percent.

    Polling from Pew has also found that conservatives overwhelmingly believe professors bring their liberal political and social views into the classroom. State legislatures have passed laws to restrict how race and racism are taught, and to limit how institutions train employees on those topics.

    As a candidate, Donald J. Trump dragged higher education onto the front lines of the culture wars, painting colleges as bastions of progressive groupthink hostile to conservative viewpoints. Trump also rolled back protections for LGBTQ students and, in 2019, signed an executive order requiring federal agencies to ensure that institutions receiving federal research grants were properly protecting free inquiry. At the signing ceremony, Trump introduced several college students who alleged that they had been punished for their political views.

    The partisan divide on higher education is also reflected in voters’ college attainment. Nearly 60 percent of those with a college degree now identify as or lean Democratic, according to the Pew Research Center, and those without a college degree are flocking to the Republican Party.

    One thing that’s totally alienated a lot of people to many higher-ed institutions is the enforced conformity of thought; the uniformity of thought.

    So far, no laws restricting instruction on “divisive topics” such as race, gender, and sexuality have been passed in Indiana, though several were proposed, according to the free-expression advocacy group PEN America, which tracks such legislation. Nationwide, nearly 20 such measures were signed into law since 2021, including bills in at least 10 states that apply to public colleges.

    In an interview, Daniels lamented the overall souring public perception of higher education. “We can’t be happy that people have become dismissive about the whole enterprise,” he said, “or decided that it can’t possibly be worth either the money or the time.” He added that he understands the frustrations of those who argue that campuses are not welcome to a range of political viewpoints. “One thing that’s totally alienated a lot of people to many higher-ed institutions,” he said, “is the enforced conformity of thought; the uniformity of thought.”

    On some issues, Daniels is willing to take a strong stand. Republican officials have attacked President Biden’s executive action to cancel up to $20,000 in federal student loans as an unconstitutional giveaway to the wealthy and an affront to those who have already paid off their education debts. The U.S. Supreme Court is scheduled to hear arguments in February from six Republican-led states, though not Indiana, that sued to stop the loan-forgiveness plan. In an interview with Fox News, Daniels called the executive order “grossly unfair to those who lived up to their responsibilities or never went to college at all. It’s grotesquely expensive and will aggravate our already terrifying national debt picture.”

    Speaking out forcefully on political issues is something few university presidents are willing to do, even on matters that could affect their campuses. A Chronicle survey found that presidents almost invariably self-censor to avoid controversy and political backlash. As a result, they increasingly find themselves caught in the middle of contentious debates on social issues, weighing the relative risks or rewards of taking a public position.

    Daniels, on the other hand, has a regular column in The Washington Post in which he airs his views on a wide variety of topics: meddlesome mothers who interfere too much in their children’s college experience, a California law meant to prohibit inhumane conditions on hog farms, and the necessity of reopening Purdue’s campus in the fall of 2020 despite the risks of Covid-19.

    Daniels’s willingness to speak out, including to publicly critique higher education, is one of the things that have made Republicans look favorably on Purdue, said Andrew Gillen, a senior policy analyst at the right-leaning Texas Public Policy Foundation. “Having him in leadership, not afraid to put his views out there,” Gillen said, “gave them a reason to trust that if something was wrong, he would tell them.”

    Daniels downplays his role as a conservative voice, and in many ways his style of politics is out of step with a party that still largely embraces Trump. Instead, Daniels said that he believes in “politics by addition, not division,” and that making college more welcoming to conservatives, generally, could be one way to stave off enrollment declines.

    “Higher education will be better off if more people, you can call them conservatives, start to feel more confidence in it.”

    Daniels is part of a still small but persistent trend of politicians who are tapped to lead college campuses. The best-known among these have been the former Democratic governor and U.S. senator David Boren, who served as president of the University of Oklahoma from 1994 to 2018, and Hank Brown, a former Republican U.S. representative and senator who was president of the University of Northern Colorado from 1998 to 2002 and the University of Colorado system from 2005 to 2008.

    The skills of a politician can be advantageous for a college president, particularly if that person is good at raising money and enjoys everyday interactions with people. “I sort of brought an affinity for that kind of thing from my last job,” Daniels said. “I always tell people, You know, you’ve got to find a way to stay in touch with the ground level.”

    For much of his career, however, Daniels served at the highest levels of both government and corporate leadership. He has a bachelor’s degree from Princeton and a law degree from Georgetown, and he began his political career working for Sen. Richard Lugar, Republican of Indiana. Daniels then ran the National Republican Senatorial Committee and became a top political adviser to President Ronald Reagan.

    George W. Bush joins Daniels onstage at a Purdue event in December. Before his election as Indiana’s governor, Daniels served as then-President Bush’s first budget director from 2001 to 2003.

    In 1987, Daniels left the White House to lead the conservative-leaning Hudson Institute and three years later became a senior executive for a pharmaceutical company. Daniels served as President George W. Bush’s budget director from 2001 to 2003.

    He twice won Indiana’s governorship, in 2004 and again in 2008. At the end of his second term, he briefly considered entering the 2012 presidential race. Instead, another opportunity presented itself: the presidency of Purdue University, where Daniels as governor had appointed or reappointed all 10 members of the Board of Trustees.

    Daniels said he was attracted to Purdue because of the opportunity to harness the university’s already strong offerings in science and engineering to generate economic activity for the region. “Anybody can see that in today’s economy, R1s, especially STEM-centric universities, are one of the great assets you can have.”

    When he arrived at Purdue, about 45 percent of undergraduates were getting degrees in STEM. That figure has now increased to nearly 70 percent, and for a student body that is about 30 percent larger. In addition, several major corporations have begun to build research and manufacturing facilities near the campus, including Rolls-Royce and Saab, which are partnering with the university’s aerospace engineers. A $1.8-billion semiconductor plant is also in the works.

    With the help of the university’s research foundation, housing is being built in West Lafayette for employees of those companies and others to bolster the population and economy in a rural area that might not otherwise attract large industries.

    Purdue has also sought to expand its brand nationally. In 2017 the university acquired the for-profit Kaplan University to create the nonprofit online Purdue University Global. But the arrangement has been plagued by concerns that it was too opaque, would dilute the university’s reputation for rigor, and become a drain on its finances. The enterprise did not break even financially until a year ago, according to an analysis by Phil Hill, an education-technology consultant.

    The goal of that arrangement, and the focus on affordability, Daniels said, is to uphold Purdue as a steppingstone for students from various backgrounds to improve their lives.

    “This is the place where people from the farms, the small towns, the inner cities, you know, have come to a public university,” Daniels said,” and I’ve heard it countless times from people like that: ‘If not for Purdue,’ ‘it started at Purdue,’ ‘I owe it to Purdue.’”

    For Daniels, one key to making Purdue a place for the less privileged to succeed has been to make it affordable. Annual in-state tuition has been set at $9,992 for all but three years since he became president. (A $10 fee for the student recreation center briefly pushed the total over $10,000, but the university’s trustees rescinded that at Daniels’ request.)

    The tuition freeze and Daniels’s other efforts to control costs are a big reason that Nadra Dunston, a sophomore studying mechanical engineering, admires Daniels. “He’s trying to utilize resources to make it affordable,” said Dunston, who is from West Lafayette, Ind.

    What has made that tuition freeze possible is a large increase in enrollment. In addition to overall growth of nearly 30 percent over the past decade, the number of undergraduates from outside Indiana, who pay tuition of up to $29,000, has more than doubled during Daniels’s tenure. (Nonresident tuition has also remained the same since 2013.) Daniels points out that the number of students from Indiana has also increased, though it has fallen from 49 percent of the student body to 40 percent since he became president.

    Freezing tuition isn’t unique to Purdue. In this case, the policy underscores Daniels’s background as a politician, noted Rebecca S. Natow, an assistant professor of educational leadership and policy at Hofstra University. “Tuition freezes are politically popular — they’re popular with students and families, and they’re popular with a lot of voters,” she said. But because of that popularity, they can be hard to undo even when they are no longer financially beneficial.

    Moreover, the kinds of policies that made Daniels a successful governor don’t necessarily work in higher education, said Michael J. Hicks, a professor of economics and director of a center for business research at Ball State University, in Muncie, Ind. He pointed to one of Daniels’s chief accomplishments as governor: overhauling the state’s bureau of motor vehicles.

    Educating college students isn’t as simple as renewing a driver’s license or registering a vehicle — basic transactions that can often be completed in a few hours or less, said Hicks, who is also on the board of scholars at the Mackinac Center for Public Policy, which advocates for free-market reforms. “Education would be nice if you could make it more efficient, but the challenge of getting a higher number of people educated isn’t transactional.”

    What Daniels did was really good for Purdue but really bad for Indiana.

    The real knock on the tuition freeze is that the university has become less accessible to low-income students. In an analysis of college-going rates in Indiana, Hicks found that the net price students were paying had increased at Purdue by nearly $1,200 between 2018 and 2020, but had fallen at the other four large public universities in the state. The reason for that increase is that Purdue is recruiting more affluent and nonresident students who pay the full sticker price of tuition, Hicks argues.

    The freeze has undermined outcomes that Daniels argued for as governor, said Hicks, including seeking to improve the share of state residents with a college degree. Since 2015, the college-going rate in Indiana has declined from 65 percent of high-school graduates to 53 percent in 2020, according to Hicks’s analysis. That decline — 12 percentage points — is double the national average, Hicks found.

    “What Daniels did was really good for Purdue,” Hicks said, “but really bad for Indiana.”

    Another free-market idea meant to reduce the burden of federal student loans was Purdue’s income-share agreements, which offered students money for college. In return, students agreed to repay a share of their income to private investors after graduating and getting a job.

    Over seven years, the program provided about $21 million to roughly 1,000 students. But the program was suspended in June after complaints from several students that the repayment terms were confusing and far more costly than they expected. In some cases, students could end up repaying 250 percent of the original amount they borrowed — far more than would have been required for a federal student loan.

    A major pillar of Daniels’s legacy at Purdue is his commitment to free speech, which he describes as central to the mission of a university.

    “Knowledge advances through the collision of ideas,” Daniels said during an interview, “and when on any subject, but especially science and so forth, when somebody says, ‘There’s one answer and only one answer, and we don’t want anybody here who doesn’t agree with that answer,’ you know, that’s anti-intellectual, that’s anti-academic.”

    His stance echoes a chief complaint among conservative activists: that higher education is a progressive echo chamber that shuts out dissenting views.

    In 2015 the university’s Board of Trustees made Purdue the first public institution to adopt the “Chicago principles,” guidelines meant to protect free expression on campus, even speech that many would find offensive or threatening. The following year Purdue began what is believed to be the first freshman orientation program dedicated to free speech. Role-playing exercises and skits demonstrate how students can react to speech they may find insulting.

    If students aren’t occasionally hearing something that offends them “there’s no free speech out there,” said Gary J. Lehman, a member of the Board of Trustees who graduated from Purdue in 1974.

    Spencer Johnson, a senior and the communications director of Purdue’s College Republicans, described a campus environment where a variety of political perspectives are shared and debated. “We don’t face massive pushback on our club’s simply existing,” said Johnson, “and really you’re free to express your ideas in class. You might have peers kind of balk at more conservative ideology … but for the most part, the professors aren’t hostile towards it.”

    Other students feel that the university has gone too far and protects individuals who make them feel unsafe.

    Rob Weiner, a doctoral student in agricultural sciences, said students have frequently complained about being harassed by street preachers on campus, but to no avail. Holding hands with a same-gender partner, Weiner said, “We were told we would burn in hell for our sexual immorality.”

    But the university has occasionally taken action, including expelling a student in 2020 for repeatedly posting what Daniels termed “racist and despicable” statements on social media, according to the Associated Press. In one instance, the student posted a video where he pretended to run over Black Lives Matter protesters.

    Daniels decided to expel the student a week after university officials announced that the posts were protected under the university’s policies.

    When Daniels was named president in 2013, faculty members were largely skeptical of his ability to successfully lead a research university. They remain, along with graduate students, Daniels’s fiercest critics.

    Their complaints are aimed, in part, at Daniels’s frugality. The tuition freeze has come at the expense of faculty pay and health-care benefits, they argue, as well as an increase in deferred maintenance on campus. Adjusted for inflation, the average salary for all instructional staff at Purdue increased 3 percent from 2012 to 2020, according to a Chronicle analysis, though salaries at similar research universities nationally declined more than 2 percent over the same period.

    The minimum graduate-student stipend at Purdue was increased last year from $20,000 to $24,500, but a living wage would require someone to make nearly $8,000 more, said Weiner, who is a member of Graduate Rights and Our Well-Being, a group that advocates for better working conditions for graduate students at Purdue.

    In April the university announced it was spending $50 million to improve pay for faculty and graduate students, calling it “the largest total investment in compensation in more than two decades.”

    The other common complaint is that Daniels has violated shared-governance principles by forcing the campus to adopt a civic-literacy requirement over the objection of the University Senate, which voted against the plan. The curriculum of the program is meant to increase students’ understanding of U.S. politics and improve civic participation.

    I believe his presidency has given Purdue an amount of cover from the legislature.

    Undergraduates at all of Purdue’s campuses have to take one of several courses in political science or history, listen to a dozen podcasts created for the curriculum and attend six approved campus events. Students must also pass a test on civic literacy in order to graduate.

    While faculty members were deeply engaged in developing the civics curriculum, the faculty senate voted against adopting it. The board approved it over the faculty’s objections, said David Sanders, associate professor of biological sciences.

    “It’s a pointless exercise, meant for external consumption,” Sanders said, “almost all about dead white males who lived at the time of the Constitution.”

    But even those who’ve clashed with Daniels acknowledge his popularity and civility. “He’s one of the smartest people I know,” said Sanders, an oft-quoted critic of the former president. His critiques were never about Daniels but about the effect of his policies, Sanders added. “We, for a long time, maintained a very cordial relationship.”

    Stephanie Masta, associate professor of curriculum studies and another frequent critic of Daniels, said there has been at least one positive from his standing as a conservative.

    “If you look at the way other red-state legislatures, they go hard after higher education, and that hasn’t happened in this very red state,” Masta said, “I believe his presidency has given Purdue an amount of cover from the legislature.”

    Purdue’s marching band honored Daniels with his own mallet to strike the group’s giant bass drum. “That’s the sort of thing, you know, I’ll not forget,” he says.

    Purdue’s marching band honored Daniels with his own mallet to strike the group’s giant bass drum. “That’s the sort of thing, you know, I’ll not forget,” he says.

    In early December, Purdue celebrated Daniels’s accomplishments, providing a tidy encapsulation of his decade-long tenure. At a street festival, the university renamed a roadway for the departing president and Daniels took selfies with students and signed T-shirts for more than two hours. Hungry attendees could snack on cookies shaped in the likeness of the president.

    At a forum titled “Freedom of Inquiry and the Advancement of Knowledge,” scholars praised the university for its commitment to free speech. Daniels also interviewed his former boss, President George W. Bush, at an event that was closed to the news media. Outside the venue, students protested.

    But walking through Purdue’s student union late in the fall semester, it’s hard to find an undergraduate who said they wouldn’t miss Daniels when he stepped down. “Our student body loves him because he shows up at different events,” said Isabel Kurien, a sophomore who is studying management and international business.

    Daniels has made himself accessible to students by eating with them in the cafeteria, working out alongside them in the fitness center, and sitting with them at football games. After a recent trustee meeting, the Purdue marching band assembled to honor Daniels with his own mallet to hit the group’s giant bass drum. “That didn’t get any notice,” he said, “but that’s the sort of thing, you know, I’ll not forget.”

    Katilina White, a senior studying political science and philosophy, said the tuition freeze and the growth in enrollment have led to a decline in course quality and a major housing shortage. But most undergraduates don’t blame Daniels, she said, because they see him as something of a caricature — a meme-like figure whose oversized face is displayed on cardboard cutouts at Boilermakers football games.

    Daniels may remain in the spotlight, but not at Purdue: He may be considering a run for the U.S. Senate next year, according to some news accounts.

    In higher education, however, the focus from conservatives will shift away from Daniels both at Purdue and nationally.

    Mung Chiang, the former dean of engineering, became president at the beginning of this year. Chiang is a study in contrasts with Daniels; an academic with extensive research and publications and no experience in politics beyond a brief stint at the U.S. State Department during the Trump administration.

    While faculty have welcomed a president with deep knowledge of academe, they are also chagrined that the trustees appointed Chiang without any search or even interviewing him formally for the position.

    Chiang won’t be entirely on his own — Daniels will retain his role as chairman of the university’s research foundation, which has been deeply involved in developing Purdue’s corporate ties. In addition, the university trustees plan to extend the tuition freeze through the end of the next academic year.

    Nationally, all eyes are on Ben Sasse, the Nebraska Republican who resigned his seat in the U.S. Senate this week to become president of the University of Florida in February. Sasse will come to the job with far more experience in higher education than most other politicians who have sought to lead universities: He has a doctorate in American history from Yale University, taught briefly at the University of Texas, and then served as president of Midland University, in Nebraska, from 2010 to 2014.

    But he is entering a job in a state where he is relatively unknown and facing backlash from faculty and students alike who raged about the process that made him the sole finalist for the position, as well as about his past criticism of same-sex marriage. Sasse has said he will try to follow Daniels’s example of eschewing partisan politics.

    Daniels said he has been in touch with Sasse in recent months and has shared some advice. “I get the question a lot: ‘So, you’ve led these other lives, you know, business and government, and so what from your past experience helped you the most?’” Daniels said.

    “I always start by saying, ‘scar tissue,’ right?” he said. “And I’m not being completely facetious.”

    Purdue University Reprimands Official Who Mocked Asian Languages At Commencement

    HAMMOND, Ind. (AP) — Purdue University said Thursday its Board of Trustees had formally reprimanded the top official of its northwestern Indiana campuses over his mocking of Asian languages during a recent commencement ceremony.

    The university’s statement released Thursday called Keon’s action an “offhand attempt at humor” that was “extremely offensive and insensitive.” The statement said while the “offensive remark does not reflect a pattern of behavior or a system of beliefs held by Dr. Keon, the Board has made clear to him that a repeat incident of a similar nature would provide grounds for further Board action, including possible dismissal.”

    Faculty senate Chairman Thomas Roach said 87% of faculty members who responded to a poll this week voted no-confidence in Keon and questioned why Purdue officials were supporting him.

    “No university faculty should be represented by somebody that they don’t accept,” Roach said.

    Purdue Northwest has about 9,000 students at campuses in Hammond and Westville.

    Purdue University Northwest faculty demand chancellor resign after racist remarks | CNN



    CNN
     — 

    The Faculty Senate Executive Committee at Purdue University Northwest (PNW) released a letter demanding Chancellor Thomas L. Keon resign after making an offensive statement during a commencement ceremony earlier this month, the committee tells CNN.

    A video posted to PNW’s official YouTube page shows Keon taking the podium on December 10 following a speech from a commencement speaker and then uttering some apparently made-up words. As the crowd laughed, he said “that’s sort of my Asian version of his….” seemingly referring to the prior speaker.

    On December 14 Keon made a public apology posted to PNW’s Twitter page. “I made a comment that was offensive and insensitive. I am truly sorry for my unplanned, off-the-cuff response to another speaker,” Keon said “I assure you I did not intend to be hurtful, and my comments do not reflect my personal or our institutional values.”

    On December 16 though, the university’s Faculty Senate Executive Committee came to a unanimous decision demanding Keon’s resignation after a discussion.

    According to Dave Nalbone, who’s a psychology professor at the university and the Vice Chair of the Faculty Senate Executive Committee, the committee sent the chancellor a letter that same day demanding he resign from his post.

    “We asked him then, and later, for a response to our demand for his resignation; to date, we have heard nothing from him,” Nalbone said in a statement to CNN.

    In the letter that was delivered to Keon the committee noted that Keon made offensive statements that insulted the Asian American and Pacific Islander community and caused national and international outrage.

    The committee also wrote that Keon’s behavior does “does not reflect the diversity and inclusiveness that Purdue faculty, staff, and students value.”

    The committee plans to follow through with a no-confidence vote and results should be in by Tuesday night, Nalbone said. The outcome of the vote doesn’t necessarily have immediate repercussions. Unless he decides to resign, the only people with removal power would be the board of trustees or president, Nalbone said.

    CNN has reached out to Chancellor Keon and Purdue’s Board of Trustees for comment.

  • Teaching Experts Are Worried About ChatGPT, but Not for the Reasons You Think

    Teaching Experts Are Worried About ChatGPT, but Not for the Reasons You Think

    Is the college essay dead? Are hordes of students going to use artificial intelligence to cheat on their writing assignments? Has machine learning reached the point where auto-generated text looks like what a typical first-year student might produce?

    And what does it mean for professors if the answer to those questions is “yes”?

    These and other questions have flooded news sites and social media since the nonprofit OpenAI released a tool called ChatGPT, which promises to revolutionize how we write. Enter a prompt and in seconds it will produce an essay, a poem, or other text that ranges in quality, users say, from mediocre to pretty good. It can do so because it has been trained on endless amounts of digital text pulled from the internet.

    Scholars of teaching, writing, and digital literacy say there’s no doubt that tools like ChatGPT will, in some shape or form, become part of everyday writing, the way calculators and computers have become integral to math and science. It is critical, they say, to begin conversations with students and colleagues about how to shape and harness these AI tools as an aide, rather than a substitute, for learning.

    Academia really has to look at itself in the mirror and decide what it’s going to be.

    In doing so, they say, academics must also recognize that this initial public reaction says as much about our darkest fears for higher education as it does about the threats and promises of a new technology. In this vision, college is a transactional experience where getting work done has become more important than challenging ourselves to learn. Assignments and assessments are so formulaic that nobody could tell if a computer completed them. And faculty members are too overworked to engage and motivate their students.

    “Academia really has to look at itself in the mirror and decide what it’s going to be,” said Josh Eyler, director of the Center for Excellence in Teaching and Learning at the University of Mississippi, who has criticized the “moral panic” he has seen in response to ChatGPT. “Is it going to be more concerned with compliance and policing behaviors and trying to get out in front of cheating, without any evidence to support whether or not that’s actually going to happen? Or does it want to think about trust in students as its first reaction and building that trust into its response and its pedagogy?”

    There is some truth underlying that nightmare vision of higher ed, of course. Budget constraints that lead to large-enrollment classes and a reliance on part-time instructors can fuel teaching that feels rote. Such problems aren’t readily solved. But others can be mitigated. Students might cheat because the value of the work of education is not apparent to them. Or their courses or curriculum don’t make any sense. Those, said Eyler, “are totally in our power to correct.”

    So how does a writing instructor, or a professor in a writing-intensive course, reduce the likelihood that students will use these AI tools? Faculty members have already come up with several ideas. Flip your teaching so that seminal pieces of work are done in class. Focus more on multimedia assignments or oral presentations. Double down on feedback and revision. Ask students to write about topics of genuine interest to them, in which their voices come through and their opinions are valued.

    If you can create an atmosphere where students are invested in learning, they are not going to reach for a workaround.

    All of those strategies may work, but underlying them, teaching experts said, is a need to talk to students about why they write. For most professors, writing represents a form of thinking. But for some students, writing is simply a product, an assemblage of words repeated back to the teacher. It’s tempting to blame them, but that’s how many students were taught to write in high school.

    Generations of students “have been trained to write simulations like an algorithm in school,” only to arrive at college to be told that writing is more than that, said John Warner, a blogger and author of two books on writing. “It feels like a bait and switch to students.”

    The challenge of creating authentic assessments — evaluations that measure true learning — has been longstanding, he noted, recalling his days as an undergraduate cramming for exams in large classes. “I forget everything I learned within hours.”

    But the vast majority of students don’t come to college wanting to bluff their way to a degree, Warner said. “If you can create an atmosphere where students are invested in learning, they are not going to reach for a workaround. They are not going to plagiarize. They are not going to copy, they are not going to dodge the work. But the work has to be worth doing on some level, beyond getting the grade.”

    At Purdue University, Melinda Zook, a history professor who runs Cornerstone, an undergraduate program that focuses on understanding and interpreting transformative texts, has advised her colleagues to “keep doing what you’re doing.” That’s because the courses are small and built around frequent feedback and discussion focused on the value and purpose of the liberal arts. ChatGPT is much less of a threat to that kind of project-based learning, she said, than to traditional humanities courses. “The fact is the professoriate cannot teach the way we used to,” she said in an email. “Today’s students have to take ownership over every step of the learning experience. No more traditional 5 paragraph essays, no more ‘read the book and write about it.’”

    Some faculty members have tried to meet the potential challenges of AI tools by incorporating them into their discussions and assignments.

    Anna Mills teaches English at the College of Marin, a community college in California that draws a lot of first-generation and lower-income students, as well as those for whom English is a second language.

    The fact is the professoriate cannot teach the way we used to. Today’s students have to take ownership over every step of the learning experience.

    In June, she began experimenting with GPT-3, an earlier version of the program on which ChatGPT was built, to test the software and read up on where it’s headed. Mills, for one, does not think using a text-producing chatbot is going to pose the same ethical quandary to students as plagiarism or contract cheating, in which you pay someone else to do the work. “They think, ‘this is a new technology. These are tools available to me. So why not use them?’ And they’re going to be doing that in a hybrid way. Some of it’s theirs and some of it’s the generators.”

    But students are also puzzled and sometimes unsettled about how this technology does what it does. That’s one reason digital literacy has to include AI language tools, she said. Mills has shown her students how Elicit, an AI research assistant, can be an effective search tool. And she assigns readings on how AI can amplify biases, such as racism and anti-Muslim rhetoric.

    She is concerned, too, that responses to ChatGPT and other AI might be inequitable. Students who are less fluent in English may be more likely to be accused of using such tools, for example, if they turn in fluid prose. Similarly, if instructors switch to oral presentations, writing in class only, or writing by hand, that could be a challenge for students with learning disabilities.

    Mills has started putting together resource lists and begun conversations with others in higher education. The Modern Language Association and the Conference on College Composition and Communication, for example, are putting together a joint task force in hopes of providing professional guidance for instructors and departments.

    “We need to become part of a societal process of thinking about, how do we want to roll this out? How should such a powerful tool be constructed?” she said. For example, “Should we just trust the tech companies to figure out how to prevent harm? Or should there be more involvement from government and from academia?”

    In August at the University of Mississippi, faculty members from the department of writing and rhetoric started holding workshops for colleagues across campus on AI’s potential impact. They are also discussing how tools such as Elicit and Fermat can help students brainstorm, design research questions, and explore different points of view.

    Preservice teacher candidates in Dave Cormier’s course at the University of Windsor will be spending the spring term looking at how AI tools will affect the future classroom. Cormier, a learning specialist for digital strategy and special projects in the Office of Open Learning, is going to ask them to consider a range of possibilities. Some might choose to incorporate such tools, others might want to dampen access to the internet in their classrooms.

    Like others, Cormier said digital literacy has to include an understanding of how AI works. One way to do that might be to ask students to run a writing prompt through a program several times over, and look for patterns in those responses. Those patterns could then lead to a discussion of where and how the tool gathers and processes data. “Getting to the next part of the story is the literacy that I’m constantly trying to bring across with my students,” he said.

    Of course, any strategy to deal with AI takes place against a backdrop of scarcity. Warner, for example, noted that first-year writing programs are often staffed by graduate students and adjunct faculty members, and that large class sizes make more intensive writing assignments a challenge.

    Alternative assignments and assessments take an investment of time, too, that some faculty members feel like they can’t spare. “There are not a lot of incentives in the structure of higher education to spend time on those things,” said Warner. In a large course, “you get locked into having to do prompts that can be assessed quickly along a limited set of criteria. Otherwise you can’t work through the stuff you have to grade.”

    Whether AI chatbots become a faculty nightmare or just another teaching tool may ultimately come down to this: Not the state of the technology, but whether professors are allowed the time to create meaningful work for their students.

  • Purdue student charged with murder in roommate’s killing

    Purdue student charged with murder in roommate’s killing

    LAFAYETTE, Ind. — A Purdue University student was charged with murder Thursday in the stabbing death of his roommate, whose body was found by officers sitting in a chair in their campus dorm room.

    Ji Min Sha, a 22-year-old cybersecurity major from Seoul, South Korea, faces one count of murder in the killing of Varun Manish Chheda, 20, of Indianapolis.

    Prosecutors allege that Sha stabbed Chheda, a data science major, several times in the head and neck with a folding knife that officers found on the floor near the chair where Chheda’s body was discovered, according to the Journal & Courier in Lafayette, Indiana.

    Purdue Police Chief Lesley Wiete said last week that Sha called police early on Oct. 5 and told them his roommate was dead in their first-floor dorm room on the campus in West Lafayette, which is about 65 miles (104 kilometers) northwest of Indianapolis.

    Officers who arrested Sha found him wearing clothes with blood on them, prosecutors said, and an autopsy found that Chheda had died of “multiple sharp-force traumatic injuries.”

    Sha appeared in court Thursday afternoon for his initial hearing before a Tippecanoe County magistrate who informed him of his rights and told Sha he could face between 45 and 60 years in prison if he’s convicted of Chheda’s murder. He is being held without bond.

    A message seeking comment from Sha’s attorney, Kyle Cray, was left Thursday afternoon by The Associated Press.

    Prosecutors have not disclosed a motive in the killing. But Sha told reporters “I was blackmailed,” when asked last week why he killed Chheda, without elaborating. He also apologized to Chheda’s family, the Journal & Courier reported.

    Purdue University student arrested in killing of roommate

    WEST LAFAYETTE, Ind. — A Purdue University student was arrested Wednesday in the killing of his roommate in their campus dorm room, authorities said.

    Ji Min Sha, a 22-year-old cybersecurity major from Seoul, South Korea, was arrested on a preliminary murder charge in the killing of 20-year-old Varun Manish Chheda, a 20-year-old data science major from Indianapolis, Purdue Police Chief Lesley Wiete said.

    Tippecanoe County Coroner Carrie Costello said an autopsy determined that Chheda died of “multiple sharp-force traumatic injuries.”

    Wiete said Sha, who goes by the nickname “Jimmy,” called police at around 12:45 a.m. “alerting us to the death of his roommate” in their first-floor dorm room on the campus in West Lafayette, which is about 65 miles (104 kilometers) northwest of Indianapolis, Wiete said.

    He has not been formally charged. Wiete said investigators don’t know why Chheda was killed, but they think he was awake at the time.

    “I believe this was unprovoked and senseless.” Wiete told reporters outside the residence hall.

    Students living near the crime scene were moved to other rooms, and the university provided counselors for those who need it, Purdue spokesman Trevor Peters told the (Lafayette) Journal & Courier.

    Purdue President Mitch Daniels said in a statement that “this is as tragic an event as we can imagine happening on our campus and our hearts and thoughts go out to all of those affected by this terrible event.”
