Genomic study ties insect evolution to the ability to detect airborne odors

[ ] A new study reveals that all insects use specialized odorant receptors that enable them to detect and pursue mates, identify enemies, find food and – unfortunately for humans –…

Molecular probe illuminates elusive cancer stem cells in live mice

[ ] After a primary tumor is treated, cancer stem cells may still lurk in the body, ready to metastasize and cause a recurrence of the cancer in a form that’s more aggressive and…

In darters, male competition drives evolution of flashy fins, bodies

[ ] Scientists once thought that female mate choice alone accounted for the eye-catching color patterns seen in some male fish. But for orangethroat darters, male-to-male competition…

Researchers first to sequence rare bacteria cause of rampant tooth decay

[ ] The most prevalent chronic disease in both children and adults, tooth decay occurs when the good and bad bacteria in our mouth become imbalanced. The bad bacteria, Streptococcus…

Study explores risk factors linked to chikungunya and dengue outbreaks

[ ] In one of the largest studies of its kind, researchers analyzed chikungunya and dengue outbreak data from 76 countries over a period of 50 years, focusing on regions across the…

Chemicals that keep drinking water flowing may also cause fouling

[ ] Many city drinking water systems add softening agents to keep plumbing free of pipe-clogging mineral buildup. According to new research, these additives may amplify the risk of…

"Stable marriages" between microbes, nutrients they eat may explain diverse yet stable communities

[ ] A mathematical model created by IGB researchers could help scientists better understand an intriguing characteristic of microbial communities: their ability to achieve stability…

Products of omega-3 fatty acid metabolism may have anticancer effects

[ ] A class of molecules formed when the body metabolizes omega-3 fatty acids could inhibit cancer’s growth and spread, University of Illinois researchers report in a new study in…

Wearable device can predict older adults’ risk of falling

[ ] Every year, more than one in three individuals aged 65 and older will experience a fall. Falls are the most common cause of injury in older adults, and can create ongoing health…

New informatics tool makes the most of genomic data

[ ] The rise of genomics, the shift from considering genes singly to collectively, is adding a new dimension to medical care; biomedical researchers hope to use the information…

Outpacing Antimicrobial Resistance Symposium

[ ] Join researchers for Outpacing Antimicrobial Resistance, a two-day symposium devoted to understanding and beating antibacterial resistant microbes, jointly hosted by the IGB, OVCR…

In responding to predation risk, secondhand experience can be as good as new

[ ] Throughout the living world, parents have many ways of gifting their offspring with information they will need to help them survive. A new study in Nature Ecology and Evolution…

Research confirms a new way for cells to conserve energy

[ ] By proving a theory that was first proposed almost 40 years ago, researchers at the IGB have confirmed a new way that cells conserve energy. The study, led by G. William Arends…

IGB World of Genomics coming to St. Louis Science Center

[ ] One of the IGB’s most successful and comprehensive public engagement events, the World of Genomics, will be showcased for three days at the St. Louis Science Center from October…

First dogs in Americas arrived from Siberia, disappeared after European contact

[ ] A study reported in the journal Science offers an enhanced view of the origins and ultimate fate of the first dogs in the Americas. The dogs were not domesticated North American…

Study reveals how polymers relax after stressful processing

[ ] The polymers that make up synthetic materials need time to de-stress after processing, researchers said. A new study has found that entangled, long-chain polymers in solutions…

Illinois' crop-counting robot earns top recognition at leading robotics conference

[ ] Today's crop breeders are trying to boost yields while also preparing crops to withstand severe weather and changing climates. To succeed, they must locate genes for high-yielding…

Researchers engineer bacteria to exhibit stochastic Turing patterns

[ ] How did the zebra get its stripes, or the leopard its spots? Mankind has been trying to answer such questions since our earliest recorded days, and they resonate throughout the…

Tiny jumping roundworm undergoes unusual sexual development

[ ] Nematodes may be among the simplest animals, but scientists can't get enough of the microscopic roundworms. They have mapped the entire genome of C. elegans, the "lab rat" of…

Researchers discover a starring role for chaperone protein Hfq in gene regulation

[ ] A cell’s efforts to respond and adapt to its external environment rely on an elaborate yet coordinated set of molecular partnerships within. The more we learn about this…
