Deaths in the family cause bacteria to flee

Indiana University Bloomington biologists report in an upcoming issue of Molecular Microbiology that exposure to the extracellular DNA (eDNA) released by dying neighbors stops the sticky holdfasts of living Caulobacter from adhering to surfaces, preventing cells from joining bacterial biofilms. ...

Riling up the immune system: P. aeruginosa polysaccharide facilitates inflammation

Being wrong isn’t always a bad thing. Take Christopher Columbus: he set out on his voyage expecting to find a shortcut to India, but landed an extended vacation in the Bahamas instead. The authors of an Observation piece just released in mBio were wrong about their assumptions, too, and although... Read More

Honey as an antibiotic: Scientists identify a secret ingredient in honey that kills bacteria

New research published in the July 2010 print edition of the FASEB Journal (http://www.fasebj.org) explains for the first time how honey kills bacteria. Specifically, the research shows that bees make a protein that they add to the honey, called defensin-1, which could one day be used to treat b... Read More

Indoor Mold Growth Is Influenced More by Location Than Building Type

In the first-ever global survey of indoor fungi scientists report that geography rather than building design and function has the greatest effect on the fungal species likely to be found indoors. The study suggests that the types of mold and other fungi most likely to be found in a dwelling may ... Read More

H1N1 deaths increase in India after onset of monsoon

NYU-Poly Professor Proposes Plan to Optimize Biosurfactants to Aid Gulf Cleanup

What if cleaning up the Gulf of Mexico wasn’t a matter of choosing between harsh chemical dispersants, labor-intensive skimming and potentially dangerous burns? Dr. Richard Gross, professor of chemical and biological science and Herman F. Mark chair at the Polytechnic Institute of New York Unive... Read More

Discovery of Controlled Swarm in Bacteria: Could Help Design New Strategies to Increase Sensitivity to Antibiotics

A study led by researchers from Universitat Autònoma de Barcelona (UAB) describes one of the mechanisms in which pathogenic bacteria populations control the way they spread over the surface of the organs they infect and stop when they detect the presence of an antibiotic, only to resume again wh...

Red tape keeps Gulf marsh cleanup on hold

At a lab on Grand Isle, La., at the edge of Barataria Bay, biologists hoping to help save the oil-soiled marshlands are at the ready with a vat containing 30,000 gallons of homegrown oil-eating bacteria. But it’s been weeks since the oil started washing up here, and still they await final clear... Read More

Computer science breakthrough: Replicating bacterial communication

Fundamental to computer science is transmitting information using electromagnetic communication - the 0s and 1s of binary code. But nature's tiniest lifeforms have used a very different method for eons, and figuring out how they do it could revolutionize computers.

Bacteria make great use of ... Read More

Watery relatives of crop pathogen P. syringae discovered in rivers

Summer’s here, and many vacationers face the question of where to spend these halcyon days: by the water or in the country? The plant pathogen Pseudomonas syringae may be in the same predicament, according to a new paper released by mBio. Morris et al. examined the genetic diversity and traits o... Read More

Can fermenting microbes save us from climate change?

Just as bacteria and fungi are methodically breaking down the millions of gallons of oil spewing into the Gulf of Mexico, microbes might help us with another uncontrolled emission due to human activity—carbon dioxide.

An anaerobic bacteria by the name of Clostridium ljungdahlii can ferment ev... Read More

Bees Help to Beat MRSA Bugs

Bees could have a key role to play in urgently-needed new treatments to fight the virulent MRSA bug, according to research led at the University of Strathclyde.

The scientists found that a substance known as beeglue or propolis, originating from beehives in the Pacific region, was active agai... Read More
