  • Brain activity reflects differences in types of anxiety

    CHAMPAIGN, Ill. - All anxiety is not created equal, and a research team at the University of Illinois now has the data to prove it. The team has found the most compelling evidence yet of differing patterns of brain activity associated with each of two types of anxiety: anxious apprehension (verbal rumination, worry) and anxious arousal (intense fear, panic, or both).

  • Illinois researchers found that the shape of a tumor may play a role in how cancer cells become primed to spread. From left: materials science and engineering professor Kristopher Kilian, graduate student Junmin Lee and veterinary medicine professor Timothy Fan.

    Shape of tumor may affect whether cells can metastasize

    Only a few cells in a cancerous tumor are able to break away and spread to other parts of the body, but the curve along the edge of the tumor may play a large role in activating these tumor-seeding cells, according to a new University of Illinois study.

  • U. of I. veterinary oncologist Dr. Timothy Fan, left, chemistry professor Paul Hergenrother and their colleagues are testing the safety of a new cancer drug in a clinical trial for humans with late-stage brain cancer.

    Corn better used as food than biofuel, study finds

    Corn is grown not only for food, it is also an important renewable energy source. Renewable biofuels can come with hidden economic and environmental issues, and the question of whether corn is better utilized as food or as a biofuel has persisted since ethanol came into use. For the first time, researchers at the University of Illinois have quantified and compared these issues in terms of economics of the entire production system to determine if the benefits of biofuel corn outweigh the costs.

  • Illinois researchers adapted CRISPR gene-editing technology to help a cell skip over mutated portions of genes. From left, professor Pablo Perez-Pinera, graduate student Alan Luu, professor Jun Song and graduate student Michael Gapinske.

    New CRISPR technique skips over portions of genes that can cause disease

    In a new study in cells, University of Illinois researchers have adapted CRISPR gene-editing technology to cause the cell’s internal machinery to skip over a small portion of a gene when transcribing it into a template for protein building. This gives researchers a way not only to eliminate a mutated gene sequence, but to influence how the gene is expressed and regulated.

    Such targeted editing could one day be useful for treating genetic diseases caused by mutations in the genome, such as Duchenne’s muscular dystrophy, Huntington’s disease or some cancers.

  • Illinois professor Aron Barbey led a study that found the functional network organization in the brain mediates the relationship between nutrition and intelligence.

    Cahokia's rise parallels onset of corn agriculture

    Corn cultivation spread from Mesoamerica to what is now the American Southwest by about 4000 B.C., but how and when the crop made it to other parts of North America is still a subject of debate. In a new study, scientists report that corn was not grown in the ancient metropolis of Cahokia until sometime between A.D. 900 and 1000, a relatively late date that corresponds to the start of the city’s rapid expansion.

  • Psychology professor Brent Roberts and his colleagues found no evidence that narcissism among college students increased between the 1990s and the 2010s. If anything, the team reports, narcissism declined over that period.

    No ‘narcissism epidemic’ among college students, study finds

    Today’s college students are slightly less narcissistic than their counterparts were in the 1990s, researchers report in a new study – not significantly more, as some have proposed. The study, reported in the journal Psychological Science, analyzed data from 1,166 students at the University of California, Berkeley in the 1990s, and from tens of thousands of students at the University of Illinois at Urbana-Champaign and the University of California, Davis in the 2000s and 2010s. All of the students completed the Narcissism Personal Inventory, the oldest and most widely used measure of narcissism.

    Disposable surgical masks best for being heard clearly when speaking, study finds

    Researcher Ryan Corey recently heard from a friend who teaches at a school where some of the students have hearing loss. The friend wanted to know if he had any ideas to help her communicate with these students while wearing a mask to slow the spread of COVID-19. Corey, who also has hearing loss, did not know what to tell her. So, he headed to the Illinois Augmented Listening Laboratory to look for solutions.

  • Graduate student Josephine Watson, professor Aditi Das, graduate student Megan Corbett, professor Kristopher Kilian and their colleagues discovered an enzymatic pathway that converts omega-3-derived endocannabinoids into more potent anti-inflammatory molecules.

    Study: Omega-3 fatty acids fight inflammation via cannabinoids

    Chemical compounds called cannabinoids are found in marijuana and also are produced naturally in the body from omega-3 fatty acids. A well-known cannabinoid in marijuana, THC, is responsible for some of its euphoric effects, but it also has anti-inflammatory benefits. A new study in animal tissue reveals the cascade of chemical reactions that convert omega-3 fatty acids into cannabinoids that have anti-inflammatory benefits – but without the psychotropic high.

  • Information sciences graduate student Joseph Porto searches through the scrapbook of a student who attended the university 100 years ago.

    Telling stories and touching history

    I slowly turn each page of Florence Lee’s large paper scrapbook, making sure not to wrinkle any of the items she placed inside. Its contents offer a snapshot of student life in the early 20th century at the University of Illinois: a laminated orange and blue button from a homecoming football game, a brochure from the Anti-Cigarette League of America, ribbons and tickets from Dad’s Day events and dozens of photographs of scenes around campus, including personal photographs of Florence Lee with her family and friends. All of these items were either glued or, in the case of some of the flat paper items, had their corners tucked into angled slots cut into the pages. The items that Florence Lee placed in this scrapbook come from her undergraduate years at the University of Illinois – 1917-20. This memento offers a window into that time.

  • With their colleagues, veterinary clinical medicine professors, from left, Dr. Ashley Mitek, Dr. Stephanie Keating and Dr. Maureen McMichael, developed an online pain management training program for veterinarians.

    Prescribing oral opioids for dogs likely doesn’t help them, veterinary experts say

    Sending ailing dogs home with oral opioids may not be an effective way to manage their pain, experts report in a free, online continuing education program recently developed for veterinarians. In light of growing evidence that such drugs don’t work well in dogs – added to the fact that humans sometimes abuse opioids prescribed for pets – the common practice of prescribing oral opioids for dogs in pain should be reexamined, the experts say.

    Anticipating the need among opioid prescribers for additional training to meet regulatory mandates, these experts created an online continuing education program that addresses the problem. The training includes cautions about unwarranted prescription of oral opioids and advice on effective pain management for veterinary patients.

  • A team of researchers led by professor Brian Fields hypothesizes that a supernova about 65 light-years away may have contributed to the ozone depletion and subsequent mass extinction of the late Devonian Period, 359 million years ago. Pictured is a simulation of a nearby supernova colliding with and compressing the solar wind. Earth’s orbit, the blue dashed circle, and the Sun, red dot, are shown for scale.

    Exploding stars may have caused mass extinction on Earth, study shows

    Imagine reading by the light of an exploded star, brighter than a full moon – it might be fun to think about, but this scene is the prelude to a disaster when the radiation devastates life as we know it. Killer cosmic rays from nearby supernovae could be the culprit behind at least one mass extinction event, researchers said, and finding certain radioactive isotopes in Earth’s rock record could confirm this scenario.
