Will Oil-Eating Bacteria Plague the Gulf?

07/01/2010
As though the Gulf Coast states don't have enough to worry about with crude oil spewing into the water at an estimated rate of 5,000 barrels a day, they soon may also have to worry about bacterial plumes. A microbe called Vibrio parahaemolyticus, common in warm coastal waters like ...

Computer science breakthrough: Replicating bacterial communication

06/30/2010
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 what's known as molecular communication, in ...

FDA: Antibiotics in Livestock Affects Human Health

06/29/2010
Giving animals antibiotics in order to increase food production is a threat to public health and should be stopped, the FDA said today. The federal agency says it has the power to ban the practice, but it's starting by issuing "draft guidance" in hopes the food industry will make voluntary changes. ...

Ever wondered why do people have bad breath in the morning?

Scientists crack chemical code that controls bacterial swarms

06/27/2010
Spanish researchers have discovered a key component of infectious bacteria's battle plan, identifying a protein that tells bacteria in a colony to halt their forward march when antibiotics are present, waiting until the coast is clear before resuming the infection.

'Hidden' tuberculosis raises drug-resistance fears

06/25/2010
Huge and hidden levels of tuberculosis discovered in a South African province devastated by HIV are increasing concerns about the prevalence of drug-resistant tuberculosis in Africa. As reported in PLoS Medicine1, when researchers examined newly deceased patients at Edendale hospital in the province of KwaZulu-Natal, they discovered that 50% were ...

Chronic fatigue syndrome: suspicion is back on virus

06/25/2010
A leading scientist at the US National Institutes of Health (NIH) supports the theory that a retrovirus causes chronic fatigue syndrome (CFS) and says that government researchers have independently confirmed the association. The link between xenotropic murine leukemia virus-related virus (XMRV) and CFS was reported last year by scientists at ...

Small Amount of Common Preservative Increases Toxins from Harmful Bacteria in Food

06/25/2010
n response to consumer demand for more natural food, the food industry has reduced the amount of preservatives in food over recent years. A common preservative is acetic acid, which is used to stop bacterial growth in dressings, sauces, cheese and pickles. However, new research shows that a small amount of ...

C-section may affect type of bacteria baby has

06/25/2010
Microbes are with us all our lives, from before the cradle to the grave. And while some are capable of killing us, most of the microbes we carry around — inside and on our skin — are part of a microbial bouquet that makes each of us who we are. Researchers ...

What's in your shopping bag? Bacteria. (But, hey, it's natural!)

06/25/2010
Way to go, all you planet-saving shoppers who've made the switch to reusable bags! But consider: "Reusable" doesn't mean "self-cleaning." Researchers at the University of Arizona and Loma Linda University queried shoppers headed into grocery stores in California and Arizona, asking them if they wash those reusable bags. The researchers ...

Study Examines, Compares Bacteria in the Nose and Throat

06/21/2010
Scientists have completed the most comprehensive comparative analysis to date of bacterial communities inhabiting the human nose and throat, which could provide new insights into why some individuals become colonized with pathogens while others do not. They release their findings today in mBio™ the online open-access journal published by ...

New Text Focuses on Microbiology of Historic Artifacts

06/21/2010
Historic and culturally important artifacts, like all materials, are vulnerable to microbial attack. Cultural Heritage Microbiology, a new text from ASM Press, offers a synthesis of important scientific articles describing microbial deterioration of cultural heritage materials and methods for conserving these objects against this decay.

Bacteria in Household Dust May Help or Hinder Childhood Asthma

04/15/2010
Bacterial populations found in household dust may determine whether or not a child living in that home develops asthma according to research published in the April 2010 issue of the journal Applied and Environmental Microbiology.

Aerosols: A New Tool Against TB?

04/15/2010
Scientists have developed a new strategy for treating tuberculosis using dry powder aerosols that could be delivered with an inhaler.
