Viruses may help keep the Earth's oxygen levels high

Oxygen is made possible in part by ocean viruses. The viruses which infect single-celled algae called cyanobacteria, are hyperefficient photosynthesisers thanks to a unique set of genes.

"Previous work had shown that cyanophage viruses have some photosynthesis genes, apparently used to keep t... Read More

Auto-brewery syndrome as a legal defense for a DUI

In 2000, researchers from the University of Washington's toxicology department published a paper that looked at the validity of "auto-brewery syndrome," a tactic lawyers apparently have used to get their clients off of a DUI charge.

"The concentration of ethanol in blood, breath or urine cons... Read More

A new national commission, the One Health Commission, has been established to spotlight the connections between human, animal, and environmental health, as well as the benefits of proactive and collaborative approaches toward better health for all.

The formation of the Commission comes at a ... Read More

H1N1/Swine Flu found in Chilean Turkeys - First reported case of human to avian transfer

On 23 Aug 2009 the Institute of Public Health (Chile) announced the first isolation of a A(H1N1) swine virus in turkeys. The finding was done by the Chilean farming agency SAG and the confirmation and genetic studies are being done in Chile's national reference laboratory.

The conclusion of t... Read More

Enzymes from bacteriophages can be used to fight multi-drug-resistant bacterial pathogens

"Scientists with the Agricultural Research Service (ARS) have shown that enzymes from bacteria-infecting viruses known as phages could have beneficial applications for human and animal health.

Phage enzymes called endolysins attack bacteria by breaking down their cell walls. Unlike antibiotic... Read More

'Synthetic biology' holds promise, but doubts simmer

This article, from USA Today, goes over the state of the science for synthetic biology. Topics covered include current research and developments in synthetic biology as well as risks and doubts about the field. Read More

The California Battle against the Asian Citrus Psyllid

In California, tests are under way on at least 100 insects that can carry a deadly citrus bacterium that were found inside a FedEx package .

"The finding this week by a sniff dog in Sacramento is the latest bad news for the state's $1.6 billion citrus industry, which has seen the Asian citru... Read More

Dead Probiotics - A Safer Bet

According to U.S. News and World Report, in 2008 some people got sick or died after receiving probiotics. "What role, if any, these bacteria played remains uncertain. Such events have, however, been giving some researchers and clinicians doubts about the safety of this ostensibly benign and "all... Read More

Enzyme may be the target for novel antibiotics

Researchers at Burnham Institute for Medical Research (Burnham), University of Texas Southwestern Medical Center and University of Maryland have demonstrated that an enzyme that is essential to many bacteria can be targeted to kill dangerous pathogens. In addition, investigators discovered chemi... Read More

Mutant bacteria + polyester = more biofuel

Brewing a certain type of biofuel with a mutant bacteria and polyester could double the fuel's production, researchers have found.

The biofuel, butanol, is a type of alcohol that is mainly used as a solvent, or in industrial processes that make other chemicals. But researchers think it has po... Read More

New genes give gut bacteria antibiotic resistance

The human gut is a reservoir of antibiotic resistance. And the bacteria residing there could bequeath their gift of resistance to more harmful microbes under the right conditions, researchers report in the August 28 Science.

Researchers at Harvard Medical School have found more resistance ge... Read More

Golden nanotubes used as imaging agent to detect tumor cells, map sentinel lymph node

(ed. note - this article is dense but interesting. Basically researchers have made progress using gold, rather than the usual carbon, to build nanotubes. The gold nanotubes can be exposed to laser pulses that carbon nanotubes can not, allowing a new range of applications.)

Craig Venter's Team Reports Key Advance in Synthetic Biology

Researchers at the J. Craig Venter Institute (JCVI), a genomic research organization, reported that they successfully transformed one bacterium into a different strain by transferring the entire bacterial genome of the first strain into a second, related strain of bacteria. In order to accomplis... Read More

Grasshoppers Can Transmit Virus to Livestock

Rangeland plants may be harboring a virus that grasshoppers are transmitting to cattle, horses and other hoofed mammals, according to a published research study by Agricultural Research Service (ARS) scientists.
