A single crafty protein allows the deadly bacterium Salmonella enterica to both invade cells lining the intestine and hijack cellular functions to avoid destruction, Yale researchers report in the April 17 issue of the journal Cell. This evolutionary slight-of-hand sheds new insights into the le...

A team of researchers has discovered a new chemical reaction for producing one of the four nucleotides, or building blocks, needed to build DNA. The reaction includes an unusual first step, or mechanism, and unlike other known reactions that produce the DNA building block, uses an enzyme that sp...

Surprise! Coxiella burnetii, the agent of Q fever, has been grown in cell-free media. This is news because, along with rickettsiae and a few others, C. burnetii is the stereotypical obligate intracellular bacterial parasite. Until now, coxiellae could only be grown within a host or in host cells...

Ozone in a bag. That's the novel method being developed by the food process engineer Dr Kevin Keener, of Purdue University, Indiana, to eliminate harmful bacteria on packaged foods such as spinach, tomatoes, and whole fruit. But rather than use an ozone generator to pump it in, Keener creates th...

Minnesota health officials are reporting an unusual death linked to a strain of polio once used in vaccines.
The Minnesota Department of Health said yesterday that a man, whom they did not identify, with symptoms of the paralyzing disease died last month. The officials said that he was infect... Read More
We all know that wine is the result of a microbiological process involving fermentation and yeast, but what's interesting about this story is the evidence that suggests Egyptians fortified their wine with certain herbs to treat disease symptoms. Some of the trace elements that have been found ar...

New study suggests waste treatment process can have an unintended consequence of spreading of extra-hardy bacteria. "To determine if sewage-treatment plants might be a source of resistant bugs, Chuanwu and fellow researchers collected several species of the common bacteria Acinetobacter from a p...

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...

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 ...

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...

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...

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...

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...
