A new study reveals a lipid structure that can support much larger proteins and molecules than before, potentially increasing the variety of drugs that can be attached to these fat molecules.Paper: Don’t rely on mixed messages to change health behaviorsSep 27, 2017 9:00 am503 views Self-improvement messages to lose weight, quit smoking or eat more fruits and vegetables can fall on deaf ears if the intervention message is mixed, says new research from U. of I. psychology professor Dolores Albarracin.Click beetles inspire design of self-righting robotsSep 25, 2017 8:30 am2078 views 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.Study: Biomarkers as predictive of sepsis as lengthy patient monitoringSep 7, 2017 8:15 am2225 views 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.Nutrition has benefits for brain network organization, new research findsSep 7, 2017 8:00 am3747 views A new study found that monounsaturated fatty acids are linked to general intelligence and the organization of the brain’s attention network.Scientists discover spring-loaded mechanism in unusual species of trap-jaw antAug 30, 2017 5:00 pm820 views Research reveals how a group of trap-jaw ants can snap their jaws shut at speeds of up to 50 miles per hour – just fast enough to capture their elusive prey.Ringing in ears keeps brain more at attention, less at rest, study findsAug 24, 2017 11:15 am4290 views 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.Study links fish stress hormones to whether they take the baitAug 22, 2017 10:00 am926 views Take a fish out of water and its stress hormones will go up. Adrenaline and noradrenaline, the “fight or flight” hormones, peak first, followed more gradually by cortisol. A new study finds that largemouth bass whose cortisol levels rise most after a brief bout of stress are inherently harder to catch by angling.Paper: Clinical signs best predictors of mortality in critically ill calvesAug 18, 2017 9:45 am954 views Clinical signs may be better predictors of mortality in neonatal calves with diarrhea than blood pH levels and other laboratory findings, suggests a new study co-written by University of Illinois researcher Peter D.

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.Studies link nutrient, academic achievement in pre-adolescent childrenJun 20, 2017 9:00 am2151 views Researchers can look into your eyes to determine whether you’re getting your lutein, a pigment found in green leafy vegetables that is known to accumulate in the brain. Two new studies find that children with higher lutein levels in the eye tend to do better than others on tests of cognition and academic achievement, even after accounting for other factors known to influence academic performance such as IQ, gender, body composition and physical fitness.Corn better used as food than biofuel, study findsJun 20, 2017 9:00 am3316 views 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.Researchers sample a DC swamp to study a spineless creatureJun 19, 2017 9:30 am1096 views CHAMPAIGN, Ill. — Its name is Stygobromus hayi, the Hay’s Spring amphipod. It is spineless. It lacks vision. It is an opportunistic feeder, consuming whatever resources are available – perhaps including the remains of its own kind. Now researchers report on a way to survey this aquatic, subterranean creature without threatening its existence, as other studies had done. Scientists find world’s oldest fossil mushroomJun 7, 2017 1:00 pm2654 views 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.Genetic study shakes up the elephant family treeJun 6, 2017 3:00 am2855 views 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.Fred A. Kummerow, successful crusader against trans fats, dies at 102Jun 1, 2017 2:45 pm1309 views 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.

By riddling the thin plastic films with pores, University of Illinois researchers made the devices sensitive enough to detect at levels that are far too low to smell, yet are important to human health.Studies link healthy brain aging to omega-3 and omega-6 fatty acids in the bloodMay 18, 2017 8:30 am2319 views 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.‘Molecular prosthetics’ can replace missing proteins to treat diseaseMay 11, 2017 1:00 pm1547 views Researchers have demonstrated that a small molecule can transport iron in human cells and live animals when proteins that normally do the same job are missing, a condition that often causes severe anemia in patients. Such “molecular prosthetics” might treat a host of incurable diseases caused by protein deficiencies, such as anemias, cystic fibrosis or certain types of heart disease.Antibiotic breakthrough: Team discovers how to overcome gram-negative bacterial defensesMay 10, 2017 12:00 pm2401 views 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.Anemonefish dads further fathering researchMay 3, 2017 8:30 am514 views Like the dad in “Finding Nemo,” anemonefish fathers will do almost anything to support their offspring. Their parenting instincts are so strong that if you give a bachelor anemonefish a scoop of anemonefish eggs from an unrelated nest, he will care for them – constantly nipping at them to remove debris and fanning them with oxygen-rich waters – as if they were his own. (Any other fish would eat them, researchers say.)Report: Even in death, indigenous border crossers marginalizedMay 2, 2017 4:30 pm470 views Of the hundreds of people who die trying to cross into the U.S. from Mexico each year, those with indigenous backgrounds are less likely to be identified than those with more European ancestry, a new analysis reveals.Study offers new insight into powerful inflammatory regulatorMay 1, 2017 2:00 pm404 views A new study in mice reveals how a protein called Brd4 boosts the inflammatory response – for better and for worse, depending on the ailment. The study is the first to show that this protein, while problematic in some circumstances, also can protect the body from infection.Team discovers a new invasive clam in the U.S.May 1, 2017 8:45 am2033 views A new invasive clam has made its official debut in North America.Brain tissue structure could explain link between fitness and memoryApr 28, 2017 9:15 am1649 views Studies have suggested a link between fitness and memory, but researchers have struggled to find the mechanism that links them.
