A single molecule in the intestinal wall, activated by the waste products from gut bacteria, plays a large role in controlling whether the host animals are lean or fatty, a research team, including scientists from UT Southwestern Medical Center, has found in a mouse study.

Using an innovative method to control the movement of Escherichia coli in a chemical environment, Emory University scientists have opened the door to powerful new opportunities in drug delivery, environmental cleanup and synthetic biology.

Waiting a day or more to get lab results back from the doctor’s office soon could become a thing of a past. Using nanotechnology, a team of University of Georgia researchers has developed a diagnostic test that can detect viruses as diverse as influenza, HIV and RSV in 60 seconds or less.

An analysis of mice infected with the reconstructed 1918 influenza virus has revealed that although the infection triggered a very strong immune system response, the response failed to protect the ani

For the first time, scientists have defined the collective genome of the human gut, or colon. Up to 100 trillion microbes, representing more than 1,000 species, make up a motley "microbiome" that allo

We assume that, off in some lab, down in a petri dish, there's a serious grudge match going on. How else to explain the fact that, mere weeks after we first heard that scientists were training viruses to create electricity, there's an announcement that another lab-coated team is coaxing microbes to produce power as well? This time, the action is at Ghent University in Belgium, where researchers have found that certain microbes are able to break down organic matter in water and produce electricity in the process. One species in particular, Brevibacillus agri, turned out to be particularly adept at turning sludge into juice, and may someday form the basis of organic fuel cells. If the virii don't get there first, that is.

A mouse immune cell that plays dual roles as both assassin and messenger, normally the job of two separate cells, has been discovered by an international team of researchers. The discovery has triggered a race among scientists to find a human equivalent of the multitasking cell, which could one day be a target for therapies [...]

An international consortium of researchers led by the University of Manchester has cracked the gene code behind a key family of fungi, which includes both the leading cause of death in leukaemia and bone marrow transplant patients and an essential ingredient of soy sauce.The ‘genome sequences’ or genetic maps for the fungi Aspergillus fumigatus, Aspergillus [...]

The ubiquitous and usually harmless E. coli bacterium, which has one-seventh the number of genes as a human, has more than 1,000 of them involved in metabolism and metabolic regulation. Activation of random combinations of these genes would theoretically be capable of generating a huge variety of internal states; however, researchers at UCSD will report [...]

Work on the world’s first human-made species is well under way at a research complex in Rockville, Md., and scientists in Canada have been quietly conducting experiments to help bring such a creature to life.Robert Holt, head of sequencing for the Genome Science Centre at the University of British Columbia, is leading efforts at his [...]
