Like an unwelcome houseguest or itinerant squatter, the human body louse shows up when times are bad and always makes them worse. Now a multi-institutional team reports that it has sequenced the body louse genome, an achievement that will yield new insights into louse "“ and human "“ biology and evolution. The study, which also sequenced the genome of a microbe that lives inside the body louse, appears in Proceedings of the National Academy of Sciences. Thanks to its tenacity, the...

Researchers have found antibiotic-resistant bacteria in seven species of sharks and redfish captured in waters off Belize, Florida, Louisiana and Massachusetts. Most of these wild, free-swimming fish harbored several drug-resistant bacterial strains. The study, published in the Journal of Zoo and Wildlife Medicine, found antibiotic-resistant bacteria in every fish species sampled. The researchers also found multidrug-resistant bacteria in fish at nearly all of the study sites, said Mark...

Researchers at the University of Illinois have developed a new, more accurate method of calculating the change in greenhouse gas emissions that results from changes in land use. The new approach, described in the journal Global Change Biology, takes into account many factors not included in previous methods, the researchers report. There is an urgent need to accurately assess whether particular land-use projects will increase or decrease greenhouse gas emissions, said Kristina...

Thanks to a new semiconductor manufacturing method pioneered at the University of Illinois, the future of solar energy just got brighter. Although silicon is the industry standard semiconductor in most electronic devices, including the photovoltaic cells that solar panels use to convert sunlight into energy, it is hardly the most efficient material available. For example, the semiconductor gallium arsenide and related compound semiconductors offer nearly twice the efficiency as silicon in...

If you're debating about what impatiens to plant in your yard, a recent study at the University of Illinois suggests that you go with Cajun Carmine, that is if you want fewer insects in your garden. Why some varieties of the popular bedding plant impatiens attract more thrips than others was one of the questions graduate student Katie Yu investigated. "The fragrances given off by flowers are actually complex compounds known as plant volatiles, some of which cannot be detected by humans," Yu...

While the laws of physics weren't made to be broken, sometimes they need revision. A major current law has been rewritten thanks to the three-port transistor laser, developed by Milton Feng and Nick Holonyak Jr. at the University of Illinois. With the transistor laser, researchers can explore the behavior of photons, electrons and semiconductors. The device could shape the future of high-speed signal processing, integrated circuits, optical communications, supercomputing and other...

In the race to find answers about ovarian cancer, researchers now have something to cluck about. For five years, University of Illinois researchers have been using the chicken as a model to study this deadly disease and have recently discovered that a diet enriched with flaxseed decreases severity of ovarian cancer and increases survival in hens. Flaxseed is the richest plant source of alpha-linolenic acid, one type of omega-3 fatty acid. Several studies have already shown that flaxseed...

Thanks to an interdisciplinary team of researchers, scientists now have a more complete understanding of one of the human body's most vital structures: the red blood cell. Led by University of Illinois electrical and computer engineering professor Gabriel Popescu, the team developed a model that could lead to breakthroughs in screening and treatment of blood-cell-morphology diseases, such as malaria and sickle-cell disease. The group published its findings in the Proceedings of the National...

They can't wait to do computational chemistry at a quadrillion calculations per second. But it's not all that computing power that's driving three Iowa State University and Ames Laboratory researchers as they develop computational chemistry at the petascale. Driving their project is the ability to run complex calculations and do better science. "Petascale power is required for accuracy," said Monica Lamm, an Iowa State assistant professor of chemical and biological engineering and associate...
