1.5-million-year-old Antarctic Microbe Community Discovered

A add-on to the picture posted here.


A living time capsule of sorts has been found buried under hundreds of feet of Antarctic ice — a colony of microbes that have been sealed off from the rest of the world for mo... Read More

Molecular Brake for the Bacterial Flagellar Nano-Motor

Biozentrum researchers have now discovered that Escherichia coli bacteria harness a sophisticated chemosensory and signal transduction machinery that allows them to accurately control motor rotation, thereby adjusting their swimming velocity in response to changing environments. The research re... Read More

Essential Oils to Fight Superbugs

Essential oils could be a cheap and effective alternative to antibiotics and potentially used to combat drug-resistant hospital superbugs, according to research presented at the Society for General Microbiology's spring meeting in Edinburgh.

Professor Yiannis Samaras and Dr Effimia Eriotou, f... Read More

Gene-Altered "Enviropig" to Reduce Dead Zones?

Move over, bacon. Here comes something greener.

A genetically engineered pig recently approved for limited production in Canada makes urine and feces that contain up to 65 percent less phosphorous, officials have announced.

That could be good news for lakes, rivers, and ocean deltas, where... Read More

Diverse Wheat Tapped for Antifungal Genes

Asian wheat may offer novel genes for shoring up the defenses of U.S. varieties against Fusarium graminearum fungi that cause Fusarium head blight (FHB) disease.

According to Agricultural Research Service (ARS) plant molecular biologist Guihua Bai, the FHB resistance found in today's U.S. wh... Read More

Dr. Rita Colwell Wins Stockholm Water Prize

Dr. Rita Colwell, an expert on the prevention of waterborne infectious diseases, has been awarded the 2010 Stockholm Water Prize, widely recognized as the world's premier award for water related research or policy work.

The prize, which includes a $150,000 award and a crystal sculpture, honor... Read More

Swine flu vaccination rates vary widely around the country

Vaccination rates for the pandemic H1N1 influenza virus have varied widely around the country, with New England having the highest vaccination rates and the South having the lowest, the Centers for Disease Control and Prevention reported Thursday in the Morbidity and Mortality Weekly Report.

What do animal studies tell us?

Rodent of the Week is devoted to highlighting promising animal research. We shine this little spotlight on animal research because, typically, it's an area we tend to ignore. While often fascinating, animal studies are conducted at such an early stage in the research process that it's irresponsi... Read More

Out of This World: New Study Investigates Infection of Human Cells in Space

In a first-of-its-kind experiment, the unique conditions of spaceflight will be used to examine how cells remain healthy or succumb to disease, particularly in the face of stress or damage.

At 3:21 a.m. PDT on April 5, ASU Biodesign Institute researchers Cheryl Nickerson and her team, includi... Read More

An alkaline lagoon inside a Volcano in Argentina teems with life

Argentinian investigators have found flamingos and mysterious microbes living in a salty, alkaline lagoon nestled inside a volcano in the Andes. The organisms, exposed to arsenic and poisonous gases, could shed light on how life began on Earth, and their hardiness to extreme conditions may hold ... Read More

Do you want to know what is in your vaccines?

The recent discovery of contaminating porcine circovirus 1 DNA in Rotarix underscores the power of deep sequencing to ensure the purity of viral vaccines. The price of deep sequencing is now low enough that it is possible to use this technology to examine not just viral vaccines, but any biologi... Read More

Take that Dengue fever, & how 'bout some of this!

As if I needed another reason to hate mosquitoes, thankfully the ones that transmit Dengue fever don't hang around the DC Metro area much. Guess this just proves that old say - "the bacterium enemy of my viral enemy is my friend" - even truer than it was before.

P.S. Anything that helps p... Read More

Virus 'cloaking device' explained by Oregon scientists

In our escalating arms race with infectious microbes, a handful of the toughest opponents have developed weapons that render vaccination seemingly worthless.

Oregon scientists now say they've figured out the defensive weapons of one the trickiest of these resilient attackers: cytomegalovirus,... Read More

Microbes reprogrammed to ooze oil for renewable biofuel

Using genetic sleight of hand, researcher Xinyao Liu and professor Roy Curtiss at Arizona State University's Biodesign Institute have coaxed photosynthetic microbes to secrete oil—bypassing energy and cost barriers that have hampered green biofuel production. Their results appear in this week's ... Read More

Military green: U.S. Air Force flies on biofuel

The U.S. Air Force burns through 2.4 billion gallons of jet fuel a year, all of it derived from oil. But a test flight on March 25 just might allow a flowering weed known as camelina to replace petroleum as part of the military's energy mix. An A-10C Thunderbolt II aircraft took flight from Elgi...

Veteran Women BioMed Researchers Still Shortchanged

You might expect young women scientists to make less than older men. But veteran female life science researchers, even in very advanced positions, still make less than their male counterparts. So finds a report in the journal Academic Medicine. [See http://bit.ly/9C7nlF]

HIV drugs could have second life as treatment for retrovirus correlated with prostate cancer

Some medications already being used to treat HIV appear to inhibit a retrovirus that has been linked to prostate cancer and chronic fatigue syndrome, reports a new study published online April 1 in PLoS ONE.

Like HIV (human immunodeficiency virus), XMRV (xenotropic murine leukemia virus-relat... Read More

Inositol or bust: genes reveal importance of inositol for Cryptococci

When Bacillus subtilis gets the chance, it establishes thick, gluey biofilms held together by a matrix of exopolysaccharides and protein. Once cells sense that there’s enough extracellular matrix, they switch over to sporulating and tend to localize themselves in aerial protrusions so they can ... Read More

Census Data Aid Disease Simulation Studies

Did you know that filling out your census card will help computer scientists model how diseases spread in the United States?

Over the last four years, researchers at RTI International in North Carolina have been transforming data from the 2000 census -- which described the country's 281 milli... Read More

The little molecules that could . . . help us unravel TB?

The more I read about Mycobacterium tuberculosis the more I'm strangely impressed by it. It's subtly devious, patient - notice how it can persist inside a host for decades - and fearsomely adaptive. A worthy adversary, to be certain. Read More
