Cannabis is a double-edged sword: by dampening the immune system, it provides relief from inflammatory diseases, but this also increase the risk of infections. Now we know how it does this: its active ingredient targets a newly discovered type of cell that lowers the immune response.

Individual blood cells flying through capillaries can now be viewed in real time. The technique, called stimulated raman scattering (SRS) microscopy, generates videos of moving cells deep inside tissue and could replace biopsies in the diagnosis of cancers.
The technique works by shining lase... Read More
Theoretical biologists at Los Alamos National Laboratory have used a New Mexico supercomputer to aid an international research team in untangling another mystery related to ribosomes -- those enigmatic jumbles of molecules that are the protein factories of living cells. The research, published D... Read More
Matchmakers: In Irish they are Babhdóir, in Yiddish they are Sadchen. For fruit flies, the matchmakers might be gut bugs.
Fruit flies (Drosophila melanogaster) with the same set of intestinal bacteria preferred mating with each other, discovered professors Eugene Rosenberg, Daniel Segel, and ... Read More
A study by a group of biologists, ecologists and medical researchers casts new light on a phenomenon farmers have known for years: the less genetic variety in a crop or a herd, the greater the risk that disease will decimate it. Biodiversity in ecosystems, the scientists report in the Thursday’s... Read More
It's electrifying: bacteria, it seems, can share energy simply through touch.
In a lab in Massachusetts, researchers have evolved a very unusual colony of symbiotic bacteria. The bacteria, which belong to two different species, cannot live without each other and grow biological wires to share... Read More
The Senate on Tuesday approved the biggest overhaul to the nation's food safety laws since the 1930s. The 73-to-25 vote gives vast new authorities to the Food and Drug Administration, places new responsibilities on farmers and food companies to prevent contamination, and -- for the first time - ...

Genetic tests have confirmed that the case of avian flu recently discovered at a farm in Shimane Prefecture was caused by a highly pathogenic virus, the farm ministry said Thursday.
The virus is also quite similar to that detected from the feces of a wild duck in Hokkaido in October this year... Read More
For the infectious diseases specialist who is hard to buy a gift for:
Four diseases have broken out in the world and it is up to a team of specialists in various fields to find cures for these diseases before mankind is wiped out. Players must work together, playing to their characters' stren... Read More
In the New York Times, Dennis Overbye discusses work just published in Science, conducted by a USGS-Menlo Park team, who trained a gammaproteobacterium taken from sediments in Mono Lake to substitute arsenic almost completely for phosphorus. The results have far-reaching consequences for astrobi... Read More
A new discovery may explain why a tuberculosis vaccine is not as effective for some people as anticipated, and potentially explains why other vaccines do not work as well for some as they do for others. In a research report presented in the December 2010 issue of the Journal of Leukocyte Biology... Read More
Media coverage of HIV/AIDS has fallen by more than 70 percent in developed countries over the last 20 years, particularly in French- and U.S.-based newspapers.
An international research team looked at approximately 69,000,000 articles in 410,000 newspaper issues. The results are detailed on a... Read More
Scientists said Thursday that they had trained a bacterium to eat and grow on a diet of arsenic, in place of phosphorus — one of six elements considered essential for life — opening up the possibility that organisms could exist elsewhere in the universe or even here on Earth using biochemical po...

According to researchers from Concordia University, Montréal, Québec, Wisconsin's favorite microbe, Lactococcus lactis, could aid in the production of biofuels by helping break down plant matter.
Scientists discovered that the scaffolding proteins on the surface of the microbe can be metaboli... Read More
NASA's secret is finally out: Researchers say they've forced microbes from a gnarly California lake to become arsenic-gobbling aliens. It may not be as thrilling as discovering life on Titan, but the claim is so radical that some chemists aren't yet ready to believe it.
If the claim holds up,... Read More
Researchers have learned the atomic-scale arrangement of proteins in a structure that enables a virus to invade and fuse with host cells, showing precisely how the structure morphs with changing acidity to initiate infection.
Findings from a team at Purdue University showed the protein struct... Read More
Could the bacteria that we carry in our bodies decide who we marry? According to a new study from Tel Aviv University, the answer lies in the gut of a small fruit fly.
Prof. Eugene Rosenberg, Prof. Daniel Segel and doctoral student Gil Sharon of Tel Aviv University's Department of Molecular M... Read More
Over the last two days, bloggers at a few of the country’s top news outlets have engaged in wild and wholly unsubstantiated speculation about the discovery of alien life.
The runaway blogging stems from a cryptic press release issued by NASA on Monday, which said that the agency would be hold... Read More
Stomach flu season is upon us, and if you or your kids have suffered through a bout of what doctors call “viral gastroenteritis”, rotavirus may well be the culprit: it is the leading cause of the illness in children. One of the virus’ secrets of success lies in how it handles calcium, namely, r... Read More
In 2007, parasite immunologist P'ng Loke sat down for lunch at a University of California, San Francisco, cafeteria with an inquisitive man who had called him earlier that week. Their chosen topic of conversation would deprive many people of an appetite, but the scientist and his guest shared an... Read More
