A microbe called Vibrio parahaemolyticus, common in warm coastal waters like the Gulf, thr... Read More

2-Billion-Year-Old Fossils May Be Earliest Known Multicellular Life

A newly discovered group of 2.1-billion-year-old fossil organisms may be the earliest known example of complex life on Earth. They could help scientists understand not just when higher life forms evolved, but why.

The fossils — flat discs almost 5 inches across, with scalloped edges and radia... Read More

Stem-cell therapy may provide new approach to fight infection

A new study shows that treatment with mesenchymal stem cells can triple survival rates in mice with sepsis, a deadly condition that can occur when an infection spreads throughout the body. The treatment reduced the damaging effects of inflammation and increased the body's ability to clear the in... Read More

Lack of sufficient iron may be a significant factor in controlling massive algae blooms

Lack of sufficient iron may be a significant factor in controlling massive blooms of Emiliania huxleyi, a globally important species of marine algae or phytoplankton, according to research led by researchers at the National Oceanography Centre (NOC) in Southampton.

Emiliania huxleyi is a spec... Read More

Deaths in the family cause bacteria to flee

Indiana University Bloomington biologists report in an upcoming issue of Molecular Microbiology that exposure to the extracellular DNA (eDNA) released by dying neighbors stops the sticky holdfasts of living Caulobacter from adhering to surfaces, preventing cells from joining bacterial biofilms. ...

Riling up the immune system: P. aeruginosa polysaccharide facilitates inflammation

Being wrong isn’t always a bad thing. Take Christopher Columbus: he set out on his voyage expecting to find a shortcut to India, but landed an extended vacation in the Bahamas instead. The authors of an Observation piece just released in mBio were wrong about their assumptions, too, and although... Read More

Honey as an antibiotic: Scientists identify a secret ingredient in honey that kills bacteria

New research published in the July 2010 print edition of the FASEB Journal (http://www.fasebj.org) explains for the first time how honey kills bacteria. Specifically, the research shows that bees make a protein that they add to the honey, called defensin-1, which could one day be used to treat b... Read More

Indoor Mold Growth Is Influenced More by Location Than Building Type

In the first-ever global survey of indoor fungi scientists report that geography rather than building design and function has the greatest effect on the fungal species likely to be found indoors. The study suggests that the types of mold and other fungi most likely to be found in a dwelling may ... Read More

NYU-Poly Professor Proposes Plan to Optimize Biosurfactants to Aid Gulf Cleanup

What if cleaning up the Gulf of Mexico wasn’t a matter of choosing between harsh chemical dispersants, labor-intensive skimming and potentially dangerous burns? Dr. Richard Gross, professor of chemical and biological science and Herman F. Mark chair at the Polytechnic Institute of New York Unive... Read More

Discovery of Controlled Swarm in Bacteria: Could Help Design New Strategies to Increase Sensitivity to Antibiotics

A study led by researchers from Universitat Autònoma de Barcelona (UAB) describes one of the mechanisms in which pathogenic bacteria populations control the way they spread over the surface of the organs they infect and stop when they detect the presence of an antibiotic, only to resume again wh...
