blog postsMassive simulation shows HIV capsid interacting with its environmentJul 19, 2017 8:30 am2646 views 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.Study: Omega-3 fatty acids fight inflammation via cannabinoidsJul 18, 2017 10:00 am3309 views 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. Brief interactions spur lasting waves of gene activity in the brainJul 17, 2017 9:00 am215 views A five-minute encounter with an outsider spurs a cascade of changes in gene activity in the brain that can last for hours, researchers report in a study of stickleback fish.Survey reveals widespread bias in astronomy and planetary scienceJul 10, 2017 10:00 am804 views In an online survey about their workplace experiences, 88 percent of academics, students, postdoctoral researchers and administrators in astronomy and planetary science reported hearing, experiencing or witnessing negative language or harassment relating to race, gender or other physical characteristics at work within the last five years. Of the 423 respondents, 39 percent reported having been verbally harassed and 9 percent said they had suffered physical harassment at work.Study: Handshaking viewed more positively by Westerners than by East AsiansJul 5, 2017 10:15 am873 views Westerners view handshaking more positively than do East Asians, researchers report in a new study.

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 am2236 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 am3682 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 am1112 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 pm4142 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 am3213 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.

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 am2626 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 pm1809 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 pm2766 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 am525 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 pm500 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 pm432 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.
