For over a century, epidemics of bacterial meningitis have swept across Africa, arriving with the dry harmattan winds to kill with terrifying speed. But on Monday, a drive starts to inoculate tens of millions of West Africans with a new vaccine in what scientists hope will be the beginning of th... Read More
A 34-year-old Northern California man with ulcerative colitis who decided to treat himself by swallowing parasitic worms has provided new information about how the worms might help to soothe and heal a variety of intestinal inflammations, researchers reported Wednesday. A growing body of evidenc... Read More
United Nations teams in Haiti believe that the cholera epidemic’s official numbers of 1,800 deaths and nearly 81,000 people infected could be double that because of difficulties in reporting, Secretary General Ban Ki-moon told the General Assembly on Friday.

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 - ...
