Why Don't We Share Data?

We are constantly hearing suggestions to make all data gathered in biology experiments available online. This is an appealing idea because most data that we collect from experiments never sees the light of day. A smattering of our data appears in papers, of course, but we all recognize that this...

Genetic Switch Potential Key To New Class Of Antibiotics

Researchers have determined the structure of a key genetic mechanism at work in bacteria, including some that are deadly to humans, in an important step toward the design of a new class of antibiotics, according to an accelerated publication that appeared online April 17 as a "paper of the week"...

Uncovering Secrets Of Salmonella's Stealth Attack

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... Read More

Newly Discovered Iron-breathing Species Have Lived In Cold Isolation For Millions Of Years

A reservoir of briny liquid buried deep beneath an Antarctic glacier supports hardy microbes that have lived in isolation for millions of years, researchers report April 17 in the journal Science. The discovery of life in a place where cold, darkness, and lack of oxygen would previously have led... Read More

New Chemical Reaction For DNA Production In Bacteria And Viruses Discovered

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... Read More

Coxiella Escapes from Cell!

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... Read More

Boston's BSL-4 Delayed Again

The opening of a biosafety laboratory level 4, built by Boston University for the study of dangerous microbes, has been delayed again after the National Institutes of Health asked for more time to complete a safety analysis, The Boston Globe reported. The National Institutes of Health now estima... Read More

Ozone in a Bag

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... Read More

Rare polio death in Minnesota

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

Egyptions Spiked Wine with Herbal Remedies

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... Read More

Waste Treatment May Spur Antibiotic Resistance Traits in Bacteria

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... Read More

'Two-handed' Marine Microbes Point To New Method For Isolating Harmful Forms Of Chemicals

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

Geoengineering the High Seas

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

A new test for bioterror agent ricin

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

New Treatment Benchmark for Starting AIDS Treatment

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

Q: Are we men or microbes?

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
