Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe. The Goddard Center for Astrobiology and the NASA Astrobiology Institute focus on this amazing field through research, experimentation, and work with scientists from all over the world. In this v...

University of Illinois at Chicago researcher Dr. John Quigley will describe a promising new approach to blocking malaria transmission during the American Society of Hematology's annual meeting in Orlando, Fla.
Quigley will speak at a press briefing Saturday, Dec. 4, at 8 a.m. at the Orange Co... Read More
Will we one day design and create molecules, cells and microorganisms that produce specific chemical products from simple, readily-available, inexpensive starting materials? Will the synthetic organic chemistry now used to produce pharmaceutical drugs, plastics and a host of other products event... Read More
Intestinal microbiology rapidly changes after Roux-en-Y gastric bypass (RYGB), adapting to the starvation-like environment, with increases in some bacteria reflecting decreasing obesity-related inflammation and some changes differing by diabetes status, according to research published in the Dec...

A U.S. researcher finds hope in the wide variance in nursing home residents who carry the bacteria Methicillin-resistant Staphylococcus aureus.
Susan Huang of the University of California-Irvine Medical Center says the high overall levels of MRSA are reason for concern but the variation in ra... Read More
Magnified 1000X, this Liefson’s flagella stained photomicrograph revealed the presence of a number of flagellated Brevundimonas diminuta, formerly known as Pseudomonas diminuta.
After having run DNA-rRNA hybridization studies, the genus Brevundimonas has been reclassified as a member of the p... Read More
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
