"The Lascaux cave in south-west France houses invaluable animal paintings that are between 16,000 and 17,000 years old, making them among the oldest examples of cave art ever found. Now conservationists must deal with the twin threats of the Fusarium solani fungus and the new bacterial populatio... Read More
The International Institute for Species Exploration at Arizona State University and an international committee of taxonomists – scientists responsible for species exploration and classification – today announce the top 10 new species described in 2008. On the list are a pea-sized seahorse, caffe... Read More
Agricultural Research Service (ARS) scientists have used antibody-coated immunomagnetic beads (IMBs) to detect Yersinia pestis, the bacterium that causes bubonic plague.
While similar techniques are often used to detect various bacterial species, the methods must be altered to suit specific p... Read More
Yes, going gluten free is trendy. And foregoing products made from wheat like bread, cookies, cakes and other processed foods is necessary for people with celiac, an auto-immune problem caused by gluten, a protein in wheat. But when there’s trendy, there’s always folks ready to trash the trend n... Read More
What is metabolomics? Oh, that's easy. It's the study of the metabolome. Very good. Now, what is the metabolome?
* the collection of all metabolites in a biological organism, which are the end products of its gene expression. (Source)
* the complete set of small-molecule metabolites ... Read More

The next flu pandemic may be hibernating in an Arctic glacier or frozen Siberian lake, waiting for rising temperatures to set it free. Then birds can deliver it back to civilization.
New research suggests an influenza virus could go into hiding in the ice when earlier generations of humans, b... Read More
US scientists claim to have successfully used bacteria to create cheap, environmentally-friendly biofuels.
According to research presented at the annual general meeting of the American Society for Microbiology, these microscopic organisms are "biological factories" that can serve as alternati... Read More
Astronauts on the space shuttle Atlantis are taking a small amount of time from their work servicing the Hubble Space Telescope to tend a commercial drug experiment aimed at finding a vaccine against a deadly staph infection that plagues hospital patients.
The astronauts essentially have to t... Read More
Know someone whose breath could peel the paint off a wall?
Then consider the OkaytoKiss - a device that gauges bad breath that was recently invented by scientists at Tel Aviv University.
The pocket-sized breath test measures malodorous bacteria in your mouth. A blue result suggests you nee... Read More
Germs really are everywhere: Bacteria, fungal spores and other biological detritus have been found in clouds and likely help to form the cores of cloud droplets, scientists have found.
The study of the role that these biological particles play in cloud formation could help refine one of the b... Read More
In a sudden surge that took Asian health officials by surprise, the Japanese health ministry confirmed on Monday at least 125 new cases of the A(H1N1) virus — or swine flu — in the country's western prefectures of Osaka and Hyogo.

Canadian researcher Sylvain Martel has developed a ultra tiny machine that can be propelled and steered through a swarm of 3,000 bacteria.
The tiny device, which measures just 300x300 microns, contains a solar cell, communications circuit and sensor. By sensing pH levels and sharing them via ... Read More
Scientists at the University of Hull, UK, think they have found a way to put a stop to red tide by exposing them to blasts of ultrasound. Michiel Postema and his colleagues tested three different frequencies on a particularly harmful species of blue-green algae, Anabaena sphaerica, which can cau... Read More
A team of University of Oregon biologists, using fruit flies, has created a way to isolate RNA from specific cells, opening a new window on how gene expression drives normal development and disease-causing breakdowns.
While DNA (deoxyribonucleic acid) provides an identical genetic blueprint ... Read More
