  • For kids with ADHD, regular 'green time' is linked to milder symptoms

    CHAMPAIGN, lll. - A study of more than 400 children diagnosed with Attention Deficit Hyperactivity Disorder has found a link between the children's routine play settings and the severity of their symptoms, researchers report. Those who regularly play in outdoor settings with lots of green (grass and trees, for example) have milder ADHD symptoms than those who play indoors or in built outdoor environments, the researchers found. The association holds even when the researchers controlled for income and other variables.

  • Study reveals 10,000 years of genetic continuity in northwest North America

    A study of the DNA in ancient skeletal remains adds to the evidence that indigenous groups living today in southern Alaska and the western coast of British Columbia are descendants of the first humans to make their home in northwest North America more than 10,000 years ago.

  • Study finds brain markers of numeric, verbal and spatial reasoning abilities

    A new study begins to clarify how brain structure and chemistry give rise to specific aspects of what researchers call “fluid intelligence,” the ability to adapt to new situations and to solve problems one has never encountered before.

  • Stem cells from muscle could address diabetes-related circulation problems

    Stem cells taken from muscle tissue could promote better blood flow in patients with diabetes who develop peripheral artery disease, a painful complication that can require surgery or lead to amputation.

    Vastly expanding sugarcane production in Brazil for conversion to ethanol could reduce current global carbon dioxide emissions by as much as 5.6 percent, researchers report in the journal Nature Climate Change.

  • Study finds parallels between unresponsive honey bees, autism in humans

    Honey bees that consistently fail to respond to obvious social cues share something fundamental with autistic humans, researchers report in a new study. Genes most closely associated with autism spectrum disorders in humans are regulated differently in unresponsive honey bees than in their more responsive nest mates, the study found.

  • 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).

  • Urbana campus faculty members named University Scholars

    Seven Urbana campus faculty members have been named University Scholars and will be honored at a campus reception Sept. 28 from 4:30 to 6 p.m. in the ballroom of the Alice Campbell Alumni Center, 601 S. Lincoln Ave., Urbana.

  • Study: Ancient mound builders carefully timed their occupation of coastal Louisiana site

    A study of ancient mound builders who lived hundreds of years ago on the Mississippi River Delta near present-day New Orleans offers new insights into how Native peoples selected the landforms that supported their villages and earthen mounds – and why these sites were later abandoned.

  • Study rewrites early history of corn in corn country

    A new study contradicts decades of thought, research and teaching on the history of corn cultivation in the American Bottom, a floodplain of the Mississippi River in Illinois. The study refutes the notion that Indian corn, or maize, was cultivated in this region hundreds of years before its widespread adoption at about 1000 A.D.

  • Many Midwestern retailers sell mislabeled invasive vines

    Gardeners hoping to celebrate the beauty of American bittersweet – a native vine that produces orange berries in the fall and is used for wreaths – may be unwittingly buying an invasive bittersweet instead. That’s because many Midwestern retailers are selling oriental bittersweet with labels misidentifying it as the native plant, researchers report. These sales are occurring in stores and online.

  • Old drugs, new tricks: Medications approved for other uses also have antibiotic action

    A number of drugs already approved to treat parasitic infections, cancers, infertility and other conditions also show promise as antibiotic agents against staph and tuberculosis infections, according to a new study by University of Illinois chemists and collaborators.

  • Survival of many of the world’s nonhuman primates is in doubt, experts report

    A report in the journal Science Advances details the grim realities facing a majority of the nonhuman primates in the world – the apes, monkeys, tarsiers, lemurs and lorises inhabiting ever-shrinking forests across the planet. The review is the most comprehensive conducted so far, the researchers say, and the picture it paints is dire.

  • Forget butterflies and bees, box like an ant: Study measures speed of trap-jaw ant boxing

    Boxer Muhammad Ali famously declared his intent to “float like a butterfly and sting like a bee,” but perhaps boxers should look to another type of insect for inspiration: the trap-jaw ant.

  • Study: Second-generation biofuels can reduce emissions

    Second-generation biofuel crops like the perennial grasses Miscanthus and switchgrass can efficiently meet emission reduction goals without significantly displacing cropland used for food production, according to a new study. Researchers from the University of Illinois and collaborators published their findings in the inaugural edition of the journal Nature Energy. The researchers call it the most comprehensive study on the subject to date.

  • Slowing dangerous bacteria may be more effective than killing them, researchers report

    A new study suggests it may be possible to slow dangerous infections by manipulating the messages microbes send to one another, allowing the body to defeat an infection without causing the bacteria to develop resistance to the treatment.

  • Emotional suppression reduces memory of negative events

    By peering at the brains of study subjects prompted to suppress negative emotions, scientists have gained new insights into how emotional regulation influences negative feelings and memories. They hope the findings will lead to new methods to combat depression.

  • Study links brain structure, anxiety and negative bias in healthy adults

    Healthy college students who have a relatively small inferior frontal cortex – a brain region behind the temples that helps regulate thoughts and emotions – are more likely than others to suffer from anxiety, a new study finds. They also tend to view neutral or even positive events in a negative light, researchers report.

  • Genomic study explores evolution of gentle ‘killer bees’ in Puerto Rico

    A genomic study of Puerto Rico’s Africanized honey bees – which are more docile than other so-called “killer bees” – reveals that they retain most of the genetic traits of their African honey bee ancestors, but that a few regions of their DNA have become more like those of European honey bees. According to the researchers, these changes likely contributed to the bees’ rapid evolution toward gentleness in Puerto Rico, a change that occurred within 30 years.

  • Fred A. Kummerow, successful crusader against trans fats, dies at 102

    Fred A. Kummerow, a pioneer in the study of dietary contributors to heart disease who led a decades-long crusade to remove trans fats from the food supply, died Wednesday, May 31, at his home in Urbana, Illinois. He was 102.

  • Breastfed babies less likely to be picky eaters as toddlers

  • Muscle-powered bio-bots walk on command

    CHAMPAIGN, Ill. - A new generation of miniature biological robots is flexing its muscle.

  • Decision-making is shaped by individual differences in the functional brain connectome

    Each day brings with it a host of decisions to be made, and each person approaches those decisions differently. A new study by University of Illinois researchers found that these individual differences are associated with variation in specific brain networks – particularly those related to executive, social and perceptual processes.

  • Force triggers gene expression by stretching chromatin

    A new study by University of Illinois researchers and collaborators in China has demonstrated that external mechanical force can directly regulate gene expression.

  • Time-lapse cell imaging reveals dynamic activity

    Living cells are miniature worlds bustling with activity. A new advanced imaging method can track cells over long periods of time using only light – no dye or chemicals required – to reveal dynamics and provide insight into how cells function, develop and interact.

  • Study: Alaskan boreal forest fires release more carbon than the trees can absorb

    A new analysis of fire activity in Alaska's Yukon Flats finds that so many forest fires are occurring there that the area has become a net exporter of carbon to the atmosphere. This is worrisome, the researchers say, because arctic and subarctic boreal forests like those of the Yukon Flats contain roughly one-third of the Earth's terrestrial carbon stores.

  • CRISPR mines bacterial genome for hidden pharmaceutical treasure

    In the fight against disease, many weapons in the medicinal arsenal have been plundered from bacteria themselves. Using CRISPR-Cas9 gene-editing technology, researchers have now uncovered even more potential treasure hidden in silent genes.

    CHAMPAIGN, Ill. — Patients with persistent ringing in the ears – a condition known as tinnitus – process emotions differently in the brain from those with normal hearing, researchers report in the journal Brain Research.

  • Study confirms long-term effects of ‘chemobrain’ in mice

    Women undergoing chemotherapy for breast cancer have long complained of lingering cognitive impairments after treatment. These effects are referred to as "chemobrain," a feeling of mental fogginess. A new study from the University of Illinois reports long-lasting cognitive impairments in mice when they are administered a chemotherapy regimen used to treat breast cancer in humans.

  • Rat study reveals long-term effects of adolescent amphetamine abuse on the brain

    A study of rats given regular, high doses of amphetamine finds that those exposed to the drug at an age corresponding to human adolescence experience long-term changes in brain function that persist into adulthood.

  • Science at Illinois feeds the world, furthers health, protects the planet

    Illinois scientists are helping power plants run more efficiently, designing better, longer-lasting batteries, finding new ways to target cancerous tumors, and developing robots that can aid in construction, in agricultural fields and even inside the human body.

  • Illinois team tackles mysterious disease afflicting wild and captive snakes

    Biologists and veterinarians across the central and eastern United States are calling on researchers at the University of Illinois to help them identify, understand and potentially treat snake fungal disease, a baffling affliction affecting more than a dozen species of wild and captive snakes in at least 15 states.

  • Exercise appears to improve brain function among younger people

    CHAMPAIGN, Ill. - As an expanding body of work continues to confirm links between exercise and improved brain function in older adults, a new study by researchers at the University of Illinois at Urbana-Champaign and Vrije Universiteit in Amsterdam suggests similar improvements among younger populations as well.

  • Nanopores could map small changes in DNA that signal big shifts in cancer

    Detecting cancer early, just as changes are beginning in DNA, could enhance diagnosis and treatment as well as further our understanding of the disease. A new study by University of Illinois researchers describes a method to detect, count and map tiny additions to DNA called methylations, which can be a warning sign of cancer, with unprecedented resolution.

  • Increased risk of suicide, mental health conditions linked to sexual assault victimization

    An analysis of nearly 200 independent studies involving more than 230,000 adult participants finds that having been sexually assaulted is associated with significantly increased risk of anxiety, depression, suicidality, post-traumatic stress disorder, substance abuse, obsessive-compulsive disorder and bipolar disorder.

  • Researchers look for ingredients of happiness around the world

    CHAMPAIGN, lll. - In 1943, American psychologist Abraham Maslow proposed that all humans seek to fulfill a hierarchy of needs, which he represented with a pyramid. The pyramid's base, which he believed must come first, signified basic needs (for food, sleep and sex, for example). Safety and security came next, in Maslow's view, then love and belonging, then esteem and, finally, at the pyramid's peak, a quality he called "self-actualization." Maslow wrote that people who have these needs fulfilled should be happier than those who don't.

  • Study identifies key player in heart enlargement

    The heart is a dynamic muscle that grows and shrinks in response to stressors such as exercise and disease. The secret to its malleability lies in individual cells, which get bigger or smaller depending on the heart’s needs. A new study of mouse hearts reveals a previously unknown mechanism by which heart cells control their size by ramping up or stopping the production of a key factor called PABPC1. The findings, reported in the journal eLife, could assist in the development of therapeutics that promote healthy heart growth and prevent disease.

  • DNA molecules directly interact with each other based on sequence, study finds

    Proteins play a large role in DNA regulation, but a new study finds that DNA molecules directly interact with one another in a way that’s dependent on the sequence of the DNA and epigenetic factors. This could have implications for how DNA is organized in the cell and even how genes are regulated in different cell types, the researchers say.

  • Tiny exports signal big shifts in cancer tissue, researchers find

    Microscopic shifts in metabolism and increases in tiny transport vesicles out of tumor cells preface larger changes to the tumor environment and could prepare the way for cancerous cells to spread and metastasize, University of Illinois researchers report.

  • Researchers develop model to show how bacteria grow in plumbing systems

    Bacteria in tap water can multiply when a faucet isn’t used for a few days, such as when a house is vacant over a week’s vacation, a new study from University of Illinois engineers found. The study suggests a new method to show how microbial communities, including those responsible for illnesses like Legionnaires’ disease, may assemble inside the plumbing systems of homes and public buildings

  • Study of pipestone artifacts overturns a century-old assumption

    CHAMPAIGN, lll. - In the early 1900s, an archaeologist, William Mills, dug up a treasure-trove of carved stone pipes that had been buried almost 2,000 years earlier. Mills was the first to dig the Native American site, called Tremper Mound, in southern Ohio. And when he inspected the pipes, he made a reasonable - but untested - assumption. The pipes looked as if they had been carved from local stone, and so he said they were. That assumption, first published in 1916, has been repeated in scientific publications to this day. But according to a new analysis, Mills was wrong.

  • Study of sleep apps finds room for improvement

    An analysis of 35 popular phone-based sleep apps finds that while most help users set sleep-related goals and track and manage their sleep, few make use of other methods known to help the chronically sleep-deprived.

  • Report: People buy most of their junk food at the supermarket

    An analysis of a nationally representative sample of U.S. adults reveals that access to healthy foods in a supermarket does not hinder Americans’ consumption of empty calories. In fact, the study found, U.S. adults buy the bulk of their sugar-sweetened beverages and nutrient-poor discretionary foods at supermarkets and grocery stores. The findings challenge the "food desert" hypothesis.

  • Cognitive cross-training enhances learning, study finds

    Just as athletes cross-train to improve physical skills, those wanting to enhance cognitive skills can benefit from multiple ways of exercising the brain, according to a comprehensive new study from University of Illinois researchers.

  • Study: How we explain things influences what we think is right

    New research focuses on a fundamental human habit: When trying to explain something (why people give roses for Valentine’s Day, for example), we often focus on the traits of the thing itself (roses are pretty) and not its context (advertisers promote roses). In a new study, researchers found that people who tend to focus on “inherent traits” and ignore context also are more likely to assume that the patterns they see around them are good.

  • Study: Future drought will offset benefits of higher CO2 on soybean yields

    An eight-year study of soybeans grown outdoors in a carbon dioxide-rich atmosphere like that expected by 2050 has yielded a new and worrisome finding: Higher atmospheric CO2 concentrations will boost plant growth under ideal growing conditions, but drought – expected to worsen as the climate warms and rainfall patterns change – will outweigh those benefits and cause yield losses much sooner than anticipated.

  • Shape-shifting agent targets harmful bacteria in the stomach

    A new shape-shifting polymer can target and kill Helicobacter pylori bacteria in the stomach without killing helpful bacteria in the gut.
