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

'Natural' Nitrogen-fixing Bacteria Protect Soybeans From Aphids

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

Vinegar may aid in groundwater cleanup

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

Bill on drug-resistant infections advances in Washington state

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

Bacteria protect soybeans from aphids

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

Gene Targeting Discovery Opens Door For Vaccines And Drugs

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

Cure For Honey Bee Colony Collapse?

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

Custom Made Steam Collector Isolates Bacteria from Hydrothermal Vents

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:

Ellis, D., R.W. Biz... Read More

Fracas Erupts Over Climate Change and Potential for Disease Spread

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

In Georgia, Rain Increases the Risks of Salmonella in Waterways

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
