Taking the temperature of the no-fly zone
Flies, unlike humans, can't manipulate the temperature of their surroundings so they need to pick the best spot for flourishing. New Brandeis University research in this week's Nature reveals that they have internal thermosensors to help them.

Bee species outnumber mammals and birds combined
Scientists have discovered that there are more bee species than previously thought. In the first global accounting of bee species in over a hundred years, John S. Ascher, a research scientist in the Division of Invertebrate Zoology at the American Museum of Natural History, compiled online species pages and distribution maps for more than 19,200 described bee species, showcasing the diversity of these essential pollinators.

Fossils found in Tibet by FSU geologist revise history of elevation, climate
About 15,000 feet up on Tibet's desolate Himalayan-Tibetan Plateau, an international research team led by Florida State University geologist Yang Wang was surprised to find thick layers of ancient lake sediment filled with plant, fish and animal fossils typical of far lower elevations and warmer, wetter climates.

Researchers Identify Biofilms That Cause Infection
Understanding the way bacterial cells "talk" to each other could lead to more effective methods for fighting the often persistent and serious infections caused by the biofilms they form, says a Texas A&M University professor of chemical engineering who not only has deciphered their language but also discovered how to quell their conversation.

Pharmaceutical study: Less hemorrhaging after stroke, but not fewer deaths
An international study published in May 2008 in the "New England Journal of Medicine" has shown that the coagulation factor VIIa can limit the extent of a cerebral hemorrhage. However, in the long term it does not prevent death or severe impairment.

UT School of Public Health researchers discover significant efficacy of travelers' diarrhea vaccine
Researchers at The University of Texas School of Public Health have found that patients given a travelers' diarrhea vaccine were significantly less likely to suffer from clinically significant diarrhea than those who received placebo, according to a study published in this week's edition of the Lancet. The patch-based vaccine is part of the Phase 2 study in conjunction with the Iomai Corporation.
