By Katrina Voss, Penn State A team of scientists led by Melissa Rolls, an assistant professor of biochemistry and molecular biology at Penn State University, has peered inside neurons to discover an unexpected process that is required for regeneration after severe neuron injury. The process was discovered during Rolls's studies aimed at deciphering the inner workings of dendrites -- the part of the neuron that receives information from other cells and from the outside world. The research will...

Conservation and international aid groups may be on the wrong course to address the havoc wreaked by climate change on tropical rainforests, according to a commentary appearing in the journal Nature on 2 December 2010. "Most of the world's terrestrial biodiversity is contained in tropical rainforests, and climate change is looming ever larger as one of the major threats to these ecosystems, but how humans deal with climate change may be even more important," said Penn State University...

For the first time, scientists have been able to "freeze in time" a mysterious process by which a critical enzyme metabolizes drugs and chemicals in food. By recreating this process in the lab, a team of researchers has solved a 40-year-old puzzle about changes in a family of enzymes produced by the liver that break down common drugs such as Tylenol, caffeine, and opiates, as well as nutrients in many foods. The breakthrough discovery may help future researchers develop a wide range of more...

By Katrina Voss, Penn State University A team of scientists has observed the activity of nerve cells in a songbird's brain as it is singing a particular song. Dezhe Jin, an assistant professor in the Department of Physics at Penn State University and one of the study's authors, explained that understanding how birds string together sets of syllables "” or notes in a song "” may provide some insight into how the human brain learns language and produces speech. The research will be...

Federal scientists have found that the oil spill caused by BP in the Gulf of Mexico may have caused damage to deep sea corals and other marine life several miles away. Researchers from the National Oceanic and Atmospheric Administration (NOAA) along with Penn State University and others examined the coral. Scientists said they took remotely operated vehicles down to 4,600 feet and about seven miles from the BP well to find dead and dying corals.  They said that some appeared to be...

By Kitta MacPherson, Princeton University Strong immunity may play a key role in determining long life, but may do so at the expense of reduced fertility, a Princeton University study has concluded. An 11-year study of a population of wild sheep located on a remote island off the coast of Scotland that gauged the animals' susceptibility to infection may give new insight into why some people get sicker than others when exposed to the same illness. The answer to this medical puzzle may lie in...

Astronomers in Japan, using an X-ray detector on the International Space Station, and at Penn State University, using NASA's Swift space observatory, are announcing the discovery of an object newly emitting X-rays, which previously had been hidden inside our Milky Way galaxy in the constellation Centaurus. The object -- a binary system -- was revealed recently when an instrument on the International Space Station named MAXI (Monitor of All-Sky X-ray Image) on the Exposed Facility of the...

The scientists who put an innovative tree of life online last year now have made that same resource available -- free -- for smartphones. The new "TimeTree" application lets anyone with an Apple iPhone harness a vast Internet storehouse of data about the diversity of life, from bacteria to humans. The intuitive interface is designed to answer a simple question, quickly and authoritatively: how long ago did species A and species B share a common ancestor? "Our new iPhone app can be fun for...

STATE COLLEGE, Pa., Sept. 2 /PRNewswire/ -- Verizon Wireless has installed a temporary cell site--called a COW, or Cell On Wheels--near Penn State University's Beaver Stadium to provide additional network coverage and calling capacity just in time for football season. This service enhancement means that more customers can use the Verizon Wireless network concurrently to make calls or use data applications such as text, picture and video messaging during home football games. "Penn State...

New research shows that when some fence lizards are attacked by fire ants they "stress out"-- a response that actually helps the species to survive by heightening the animal's awareness of imminent danger. Tracy Langkilde, assistant professor of biology at Penn State University, found that lizards living in areas of the southeastern United States, where large numbers of fire ants also live, have elevated levels of stress hormones, called glucocorticoids. The stress-hormone study comes on the...
