A complex sugar may someday become one of the most effective weapons to stop the spread of cholera, a disease that has claimed thousands of lives in Haiti since the devastating earthquake last year.

CORVALLIS, Ore. – A new analysis of the Northern Hemisphere's "albedo feedback" over a 30-year period concludes that the region's loss of reflectivity due to snow and sea ice decline is more than double what state-of-the-art climate models estimate.
The findings are important, researchers say, because they suggest that Arctic warming amplified by the loss of reflectivity could be even more significant than previously thought.
(Boston) – Researchers from Boston University School of Medicine (BUSM) have for the first time shown that reduced vitamin D absorption in patients with quiescent Crohn's disease (CD) may be the cause for their increased risk for vitamin D deficiency. The findings, which currently appear on-line in Inflammatory Bowel Diseases, also showed that the only way to determine absorption efficiency is to perform a vitamin D bioavailability test.
WASHINGTON -- The first global simulation study of equatorial spread F (ESF) bubble evolution using a comprehensive 3D ionosphere model, SAMI3, has been demonstrated. The model self-consistently solves for the neutral wind driven dynamo electric field and the gravity driven electric field associated with plasma bubbles.

ANN ARBOR, Mich.---With an invention that can be made from some of the same parts used in CD players, University of Michigan researchers have developed a way to measure the growth and drug susceptibility of individual bacterial cells without the use of a microscope.
The new biosensor promises to speed treatment of bacterial infections, said Raoul Kopelman, who is the Richard Smalley Distinguished University Professor of Chemistry, Physics and Applied Physics and a professor of biomedical engineering, biophysics and chemical biology.
If you wander up to a seismograph in a museum, unless you are lucky enough to be there right during an earthquake, all you will see is a small wiggly signal being recorded.
What's inside the wiggles is called noise by seismologists, because the signal is always there and originates from the normal activity of the earth between the jolts caused by large earthquakes.
The magnitude of climate change during Earth's deep past suggests that future temperatures may eventually rise far more than projected if society continues its pace of emitting greenhouse gases, a new analysis concludes.
The study, by National Center for Atmospheric Research (NCAR) scientist Jeffrey Kiehl, will appear as a "Perspectives" article in this week's issue of the journal Science.
Wild red deer on the Isle of Rum, which were featured in the BBC TV series Autumnwatch, are rutting earlier in the year, a study shows.
Scientists believe the annual rutting season on the Isle of Rum could be changing because of warming spring and summer temperatures. The study shows that the rutting and calving seasons are now up to two weeks earlier on average compared with 30 years ago.
The research was based on a 38-year study of the ecology of red deer on the Isle of Rum and used annual records of breeding success in more than 3,000 individually recognisable deer.

CHAMPAIGN, Ill. — Researchers at the University of Illinois and Northwestern University have demonstrated bio-inspired structures that self-assemble from simple building blocks: spheres.
A new assessment of global earthquake fatalities over the past three decades indicates that 83 percent of all deaths caused by the collapse of buildings during earthquakes occurred in countries considered to be unusually corrupt.
New results from a Baylor University study show that different behaviors and strategies lead some families to cope better and emerge stronger after a weather-related event.
In the late 1950s, Richard Feynman famously imagined a science where researchers and engineers could achieve remarkable feats by manipulating matter and creating structures all the way down to the level of individual atoms.
