SANTA BARBARA, Calif., Sept. 16, 2010 — In the aftermath of the Deepwater Horizon disaster in the Gulf of Mexico, a team of scientists led by UC Santa Barbara's David Valentine and Texas A&M University's John Kessler embarked on a research cruise with an urgent mission: determining the fate and impact of hydrocarbon gases escaping from a deep-water oil spill.

PITTSBURGH, Sept. 15 – Fat-derived stem cells can be safely used to aid reconstruction of breast tissue after mastectomy as long as there is no evidence of active cancer, according to researchers at the University of Pittsburgh School of Medicine. Their findings are available in Tissue Engineering Part A.

WEST LAFAYETTE, Ind. - Researchers at Purdue University have developed a facility aimed at learning precisely how coal and biomass are broken down in reactors called gasifiers as part of a project to strengthen the scientific foundations of the synthetic fuel economy.

Lisbon, Portugal: Many children are being put at risk by parents over-use of widely-available over the counter (OTC) medicines for fever, coughs and colds, says a study from Australia to be presented to the annual conference of the International Pharmaceutical Federation (FIP) today (Monday 30 August). The researchers, led by Dr. Rebekah Moles from the University of Sydney, New South Wales, say that dosing errors and inappropriate use of such medicines lead to a large number of calls to poison centres as well as emergency hospital admissions.

The Arctic sea ice cover appears to have reached its minimum extent for the year, the third-lowest recorded since satellites began measuring sea ice extent in 1979, according to the University of Colorado at Boulder's National Snow and Ice Data Center.

New Haven, Conn.—Navigating our way down the street is something most of us take for granted; we seem to recognize cars, other people, trees and lampposts instantaneously and without much thought. In fact, visually interpreting our environment as quickly as we do is an astonishing feat requiring an enormous number of computations—which is just one reason that coming up with a computer-driven system that can mimic the human brain in visually recognizing objects has proven so difficult.

Recent puzzling observations of tiny variations in nuclear decay rates have led some to question the science of using decay rates to determine the relative ages of rocks and organic materials. Scientists from the National Institute of Standards and Technology (NIST), working with researchers from Purdue University, the University of Tennessee, Oak Ridge National Laboratory and Wabash College, tested the hypothesis that solar radiation might affect the rate at which radioactive elements decay and found no detectable effect.

OAK RIDGE, Tenn., Sept. 15, 2010 -- New insight into the structure of switchgrass and poplars is fueling discussions that could result in more efficient methods to turn biomass into biofuel.

Your friends are probably more popular than you are. And this "friendship paradox" may help predict the spread of infectious disease.

Air Force Office of Scientific Research-sponsored researcher, Dr. Robert Wood of Harvard University is leading the way in what could become the next phase of high-performance micro air vehicles for the Air Force.

Tackling today's complex scientific questions often requires work from interdisciplinary collaborative research teams – and working in those teams can create its own problems. Now a group of researchers from around the country, including North Carolina State University, has published a commentary in the journal Science Translational Medicine outlining a new field of study that will help resolve problems facing interdisciplinary research teams.

Rosemont, Ill. – Several health plans have introduced physician rating systems to offer consumers more information when choosing their doctors. However, a recent study presented in the September issue of the Journal of Bone and Joint Surgery (JBJS) reveals that physician-tiering guidelines and results are not consistent across insurance companies, do not fully define quality; and could confuse consumers.
