  • Team finds first wild alligator snapping turtle in Illinois since 1984

    Researchers report the first sighting in 30 years of a wild alligator snapping turtle in Illinois. The discovery may be a sign of hope for this state-endangered species, or the animal could be the last of its kind to have survived in Illinois without human intervention, the researchers say.

  • Study adds to evidence that viruses are alive

    A new analysis supports the hypothesis that viruses are living entities that share a long evolutionary history with cells, researchers report. The study offers the first reliable method for tracing viral evolution back to a time when neither viruses nor cells existed in the forms recognized today, the researchers say.    

  • Researchers track the secret lives of feral and free-roaming house cats

    CHAMPAIGN, lll. - Researchers (and some cat-owners) wanted to know: What do feral and free-roaming house cats do when they're out of sight? A two-year study offers a first look at the daily lives of these feline paupers and princes, whose territories overlap on the urban, suburban, rural and agricultural edges of many towns.

    Eight University of Illinois researchers have been named to the Thomson Reuters / Clarivate Analytics Highly Cited Researchers list for 2016. The list identifies scientists “whose research has had significant global impact within their respective fields of study."

  • Tiny electronic implants monitor brain injury, then melt away

    A new class of small, thin electronic sensors can monitor temperature and pressure within the skull – crucial health parameters after a brain injury or surgery – then melt away when they are no longer needed, eliminating the need for additional surgery to remove the monitors and reducing the risk of infection and hemorrhage.

  • Drinking more water associated with numerous dietary benefits, study finds

    In a new study of more than 18,300 U.S. adults, U. of I. researcher Ruopeng An found the majority of people who increased their consumption of plain water reduced their total daily calorie intake as well as their consumption of saturated fat, sugar, sodium and cholesterol.

  • Brief diversions vastly improve focus, researchers find

    CHAMPAIGN, lll. - A new study in the journal Cognition overturns a decades-old theory about the nature of attention and demonstrates that even brief diversions from a task can dramatically improve one's ability to focus on that task for prolonged periods.

  • Study links nutrition to brain health and intelligence in older adults

    A study of older adults offers insight into how a pigment found in leafy greens that tends to accumulate in brain tissue may contribute to the preservation of “crystallized intelligence,” the ability to use the skills and knowledge one has acquired over a lifetime.

  • Ringing in ears keeps brain more at attention, less at rest, study finds

    Tinnitus, a chronic ringing or buzzing in the ears, has eluded medical treatment and scientific understanding. A new study by University of Illinois researchers found that chronic tinnitus is associated with changes in certain networks in the brain, and furthermore, those changes cause the brain to stay more at attention and less at rest.

  • Quick test finds signs of sepsis in a single drop of blood

    A new portable device can quickly find markers of deadly, unpredictable sepsis infection from a single drop of blood.

  • 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.

  • A 20-minute bout of yoga stimulates brain function immediately after

    CHAMPAIGN, lll. - Researchers report that a single, 20-minute session of Hatha yoga significantly improved participants' speed and accuracy on tests of working memory and inhibitory control, two measures of brain function associated with the ability to maintain focus and take in, retain and use new information. Participants performed significantly better immediately after the yoga practice than after moderate to vigorous aerobic exercise for the same amount of time.

  • Scientists test nanoparticle drug delivery in dogs with osteosarcoma

    At the University of Illinois, an engineer teamed up with a veterinarian to test a bone cancer drug delivery system in animals bigger than the standard animal model, the mouse. They chose dogs – mammals closer in size and biology to humans – with naturally occurring bone cancers, which also are a lot like human bone tumors.

  • Mantis shrimp-inspired camera enables glimpse into hidden world

    By mimicking the eye of the mantis shrimp, Illinois researchers have developed an ultra-sensitive camera capable of sensing both color and polarization. The bioinspired imager can potentially improve early cancer detection and help provide a new understanding of underwater phenomena, the researchers said.

  • 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.

  • Scientists find world’s oldest fossil mushroom

    Roughly 115 million years ago, when the ancient supercontinent Gondwana was breaking apart, a mushroom fell into a river and began an improbable journey. Its ultimate fate as a mineralized fossil preserved in limestone in northeast Brazil makes it a scientific wonder, scientists report in the journal PLOS ONE.

  • Lutein may counter cognitive aging, study finds

    Spinach and kale are favorites of those looking to stay physically fit, but they also could keep consumers cognitively fit, according to a new study from University of Illinois researchers.

  • Is Academia Waking Up to the Problem of Sexual Harassment?

    U. of I. anthropology professor Kathryn Clancy supports a federal legislative effort that would require universities to report – and federal funding agencies to consider – findings that any university professor engaged in discrimination on the basis of sex. 

  • 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. 

  • Surgical probe seeks out where cancer ends and healthy tissue begins

    CHAMPAIGN, Ill. – A new surgical tool that uses light to make sure surgeons removing cancerous tumors “got it all” was found to correlate well with traditional pathologists’ diagnoses in a clinical study, showing that the tool could soon enable reliable, real-time guidance for surgeons.

  • Tumor-targeting system uses cancer’s own mechanisms to betray its location

    By hijacking a cancer cell’s own metabolism, researchers have found a way to tag and target elusive cancers with small-molecule sugars. This opens treatment pathways for cancers that are not responsive to conventional targeted antibodies, such as triple-negative breast cancer.

  • Human trials of cancer drug PAC-1 continue with new investment

    Clinical trials of the anti-cancer agent PAC-1 are continuing to expand, thanks to a $7 million angel investment from an anonymous contributor who originally invested $4 million to help get the compound this far in the drug-approval pipeline.

  • Some plants grow bigger – and meaner – when clipped, study finds

    Some plants behave like the mythical monster Hydra: Cut off their heads and they grow back, bigger and better than before. A new study finds that these “overcompensators,” as they are called, also augment their defensive chemistry – think plant venom – when they are clipped.

  • Genetic study shakes up the elephant family tree

    New research reveals that a species of giant elephant that lived 1.5 million to 100,000 years ago – ranging across Eurasia before it went extinct – is more closely related to today’s African forest elephant than the forest elephant is to its nearest living relative, the African savanna elephant.

  • Scientists tweak photosynthesis to boost crop yield

    Researchers report  that they can increase plant productivity by boosting levels of three proteins involved in photosynthesis. This confirms a hypothesis some in the scientific community once doubted was possible.

    A new analysis reveals just how much Americans are adding to their caloric intake by spicing up or sweetening their coffee or tea.

  • Study offers clearest picture yet of how HIV defeats a cellular defender

    A new study offers the first atomic-scale view of an interaction between the HIV capsid - the protein coat that shepherds HIV into the nucleus of human cells - and a host protein known as cyclophilin A. This interaction is key to HIV infection, researchers say.

  • Report: Milkweed losses may not fully explain monarch butterfly declines

    Monarch butterfly declines cannot be attributed merely to declines in milkweed abundance, researchers report.

  • 'Bad cholesterol' indicates an amino acid deficiency, researcher says

    CHAMPAIGN, Ill. - Low-density lipoprotein (LDL), the "bad cholesterol" that doctors consider a sign of potential heart disease, is merely a marker of a diet lacking all of the essential amino acids, says University of Illinois comparative biosciences professor Fred Kummerow, 99, a longtime opponent of the medical establishment's war on cholesterol.

  • Report: A host of common chemicals endanger child brain development

    In a new report, dozens of scientists, health practitioners and children’s health advocates are calling for renewed attention to the growing evidence that many common and widely available chemicals endanger neurodevelopment in fetuses and children of all ages.

  • Theory: Flexibility is at the heart of human intelligence

    Centuries of study have yielded many theories about how the brain gives rise to human intelligence. A new theory makes the case that the brain’s dynamic properties – how it is wired but also how that wiring shifts in response to changing intellectual demands – are the best predictors of intelligence in the human brain.

  • Antibiotic breakthrough: Team discovers how to overcome gram-negative bacterial defenses

    Scientists report that they now know how to build a molecular Trojan horse that can penetrate gram-negative bacteria, solving a problem that for decades has stalled the development of effective new antibiotics against these increasingly drug-resistant microbes. The findings appear in the journal Nature.

  • Fresh look at burials, mass graves, tells a new story of Cahokia

    A new study challenges earlier interpretations of an important burial mound at Cahokia, a pre-Columbian city in Illinois near present-day St. Louis. The study reveals that a central feature of the mound, a plot known as the “beaded burial,” is not a monument to male power, as was previously thought, but includes both males and females of high status.

  • 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.

  • Six Illinois professors named Guggenheim Fellows

    Six professors at the University of Illinois have been named 2016 Guggenheim Fellows, bringing to 13 the number of U. of I. faculty members who have been honored with the fellowship over the last three years. This year’s fellows are Dennis Baron, Karin A. Dahmen, Craig Koslofsky, Mei-Po Kwan, Ralph W. Mathisen and Rebecca Stumpf.

  • Massive simulation shows HIV capsid interacting with its environment

    It took two years on a supercomputer to simulate 1.2 microseconds in the life of the HIV capsid, a protein cage that shuttles the HIV virus to the nucleus of a human cell. The 64-million-atom simulation offers new insights into how the virus senses its environment and completes its infective cycle.

  • Bacterial hole puncher could be new broad-spectrum antibiotic

    Bacteria have many methods of adapting to resist antibiotics, but a new class of spiral polypeptides developed at the University of Illinois targets one thing no bacterium can live without: an outer membrane.

  • Feeling anxious? Check your orbitofrontal cortex and cultivate your optimism, study suggests

    A new study links anxiety, a brain structure called the orbitofrontal cortex, and optimism, finding that healthy adults who have larger OFCs tend to be more optimistic and less anxious.

  • Counseling, antidepressants change personality (for the better), team reports

    A review of 207 studies involving more than 20,000 people found that those who engaged in therapeutic interventions were, on average, significantly less neurotic and a bit more extraverted after the interventions than they were beforehand.

  • Studies link healthy brain aging to omega-3 and omega-6 fatty acids in the blood

    Two new studies link patterns of polyunsaturated fatty acids in the blood to the integrity of brain structures and cognitive abilities that are known to decline early in aging.

  • Light illuminates the way for bio-bots

    A new class of miniature biological robots, or bio-bots, has seen the light – and is following where the light shines.

  • Study: Emotion processing in the brain changes with tinnitus severity

    A new study reveals that people with tinnitus who are less bothered by their symptoms use different brain regions when processing emotional information.

  • Genome mining effort discovers 19 new natural products in four years

    It took a small group of researchers only four years – a blink of an eye in pharmaceutical terms – to scour a collection of 10,000 bacterial strains and isolate the genes responsible for making 19 unique, previously unknown phosphonate natural products, researchers report. Each of these products is a potential new drug. One of them has already been identified as an antibiotic.

  • Study: Biomarkers as predictive of sepsis as lengthy patient monitoring

    One measurement of key biomarkers in blood that characterize sepsis can give physicians as much information as hours of monitoring symptoms, a new study found.

  • Click beetles inspire design of self-righting robots

    Robots perform many tasks that humans can’t or don’t want to perform, getting around on intricately designed wheels and limbs. If they tip over, however, they are rendered almost useless. A team of University of Illinois mechanical engineers and entomologists are looking to click beetles, who can right themselves without the use of their legs, to solve this robotics challenge.

  • Researchers resolve structure of a key component of bacterial decision-making

    For bacteria that swim, determining whether to stay the course or head in a new direction is vital to survival. A new study offers atomic-level details of the molecular machinery that allows swimming bacteria to sense their environment and change direction when needed
