Scientists studying how marine bacteria move have discovered that a sharp variation in water current segregates right-handed bacteria from their left-handed brethren, impelling the microbes in opposite directions. This finding and the possibility of quickly and cheaply implementing the segregati... Read More
Would adding iron to the Southern Ocean's Drake Passage promote planktonic growth that in turn would help reduce the amount of CO2 in the atmosphere and curb global warming? Researchers on the high seas are considering the options in a post on Wired's Science blog. "While we concern ourselves ... Read More
Scientists say they have developed a fast and super-sensitive new test for ricin, a poison found in castor beans that scientists say is a prime candidate for use in bioterrorism attacks. The new method, described in research recently published in Analytical Chemistry, takes only three minutes to... Read More
Researchers have identified a new benchmark for starting drug treatment for AIDS.
"The question of when to start therapy has been a “swinging pendulum,” notes an editorial accompanying the study. The marker in question is the CD4 count, which represents how many of the cells that the AIDS vir... Read More
Great post on the symbiotic relationship between humans and microbes (aka The Microbiome). "there’s a growing consensus among scientists that the relationship between us and our microbes is much more of a two-way street. With new technologies that allow scientists to better identify and study t... Read More
An invasion of soybean aphids poses a problem for soybean farmers requiring application of pesticides, but a team of Penn State entomologists thinks a careful choice of nitrogen-fixing bacteria may provide protection against the sucking insects. Soybeans are legumes, plants that can have a symbi... Read More
A University of Leeds research team found adding dilute acetic acid - vinegar - to groundwater sites contaminated with harmful chromium compounds boosts the growth of naturally-occurring bacteria by providing an attractive food source. This is turn halps the bacteria to biodegrade the harmful co... Read More
A bill in Washington State's legislature designed to cut the spread of drug-resistant staph infections passed the Senate Monday. It requires health professionals to note on death certificates when the deadly bacteria played a role in a patient's demise. The bill is designed to aid the state in m... Read More
U.S. entomologists claim a careful choice of nitrogen-fixing bacteria might provide soybean farmers protection against an invasion of soybean aphids.
"Our results demonstrate that plant-rhizobia interactions influence plant resistance to insect herbivores and that some rhizobia strains confer... Read More
In a genetic leap that could help fast track vaccine and drug development to prevent or tame serious global diseases, DMS researchers have discovered how to destroy a key DNA pathway in a wily and widespread human parasite. The feat surmounts a major hurdle for targeting genes in Toxoplasma gond... Read More
For the first time, scientists have isolated the parasite Nosema ceranae (Microsporidia) from professional apiaries suffering from honey bee colony depopulation syndrome. They then went on to treat the infection with complete success. In a study published in the new journal from the Society for ... Read More
This video shows a demonstration of how to use a custom made steam collector designed to condense steam from geothermal vents (aka., fumaroles). This device was used used to collect samples of halophilic Archaea from fumaroles around the world, work which was published in:

A fray has broken out among ecologists over a study suggesting that climate change might not spread tropical diseases far and wide after all. When the paper triggered an uproar, editors at the journal Ecology decided to publish not one but six responses alongside the original research. The colle... Read More
Researchers at the University of Georgia in Athens (U.G.A.) have found that rain ups the risk of salmonella in rivers and streams—and, in turn, in products nourished by and washed in tainted runoff waters. The scientists report in Applied and Environmental Microbiology that 79 percent of water s... Read More
Cases of food-borne illnesses, including infections such as salmonella and Escherichia coli that have been at the center of recent outbreaks, have held steady for the past four years, federal health officials said today. The good news is that this is after several years of falling case numbers. Read More
The prevalence of a certain form of drug-resistant bacteria, called multidrug-resistant gram-negative (MDRGN) organisms, far surpassed that of two other common antimicrobial-resistant infections in long-term care facilities, according to a study conducted by researchers at Hebrew SeniorLife's In...

LIKE many other activities, global health has fashions. For the past couple of decades AIDS has captured both the imagination and the research dollars. Recently, though, the focus has shifted towards malaria, which kills a million people a year, most of them children, and debilitates hundreds of... Read More
The company whose salmonella-tainted peanut products made 691 people sick and may have killed nine others has been fined $14.6 million.
The Texas Department of State Health Services yesterday fined Plainview Peanut Corp. — a plant owned by the Peanut Corporation of America (PCA), the company ... Read More
A new statistical method that can estimate the origin and time of an aerosolized release of the pathogen causing anthrax, following detection of the first few cases has been developed by researchers from the Medical Research Council (MRC) Centre for Outbreak Analysis and Modelling at Imperial Co...
