Superbug Risk To War Wounded

Soldiers who survive severe injuries on battlefields such as those in Iraq and Afghanistan can be at risk from developing infections of their wounds with multidrug resistant bacteria. The potentially lethal microbes include superbugs such as methicillin resistant Staphylococcus aureus (MRSA), Ac... Read More

San Diego Science Festival - Dr. Stanley Maloy on Salmonella

Dr. Stanley Maloy discusses microbiology and Salmonella with the students of High Tech Middle in Pt. Loma during the San Diego Science Festival. Read More

Stay out of caves, save a bat

The U.S. Fish & Wildlife Service this week advised people to stay out of caves in the Northeast to hopefully slow the spread of white-nose syndrome (WNS), a deadly fungal infection blamed for the deaths of as many as half-a-million bats over the past two years. Read More

Bacteria Tapped to Battle Crop-Damaging Roundworms

Beneficial bacteria, aided by a "cocktail" of potent natural compounds, may offer a way to biologically control soybean cyst nematodes and other crop-damaging roundworms. That's the implication of ongoing studies by scientists with the Agricultural Research Service (ARS) and the Donald Danforth ... Read More

Discovery Of Tuberculosis Bacterium Enzyme Paves Way For New TB Drugs

A team of University of Maryland scientists has paved the way for the development of new drug therapies to combat active and asymptomatic (latent) tuberculosis infections by characterizing the unique structure and mechanism of an enzyme in M. tuberculosis, the bacterium that causes the disease.

Why Some People Shake Off The Flu In A Couple Of Days, While Others Suffer Longer, Or Die

For some people it is a certainty: as soon as the annual flu season gets underway, they are sure to go down with it. It is little comfort to know that there are other people who are apparently resistant to flu or overcome the illness after just a couple of days. It is this phenomenon that is now... Read More

New Way To Battle MRSA And Superbugs

Experts from Queen's University Belfast have developed new agents to fight MRSA and other hospital-acquired infections that are resistant to antibiotics. The fluids are a class of ionic liquids that not only kill colonies of these dangerous microbes, they also prevent their growth. Read More

Solid catalyst simplifies turning algae into biodiesel

As home biodiesel brewers know, it's a time-consuming and chemically intensive process to transform French fry grease into a fuel. And then there's the problem of burning something in your truck that could have fed people; canola oil can be used for food or fuel, for example. Read More

Biomass: Can Renewable Power Grow on Trees?

Dear EarthTalk: There’s a lot of talk today about solar and wind power, but what about biomass? How big a role might this renewable energy source play in our future? Couldn’t everyday people burn their own lawn and leaf clippings to generate power?
-- Deborah Welch, Niagara Falls, NY

Sweet Home Microbiology?!

Found this little southern rock classic reworked for the microbiology-minded via YouTube. It's pretty funny, if not outright ridiculous. Here are the lyrics: Big spores keep on drifting Carry me to my new hosts skin Contact airborne isolation Its time to infect someone again I know its a sin M... Read More

Salmonella Evolves into Something More in Space

Research conducted on the International Space Station in 2006 and 2008 has finally revealed for certain something that virology experts have suspected for a long time, and namely that salmonella grows to be more or less dangerous depending on its environment. In the micro-gravity surroundings of... Read More

Oral Yogurt 'Vaccine' Could Blunt Ouch Factor

Imagine how much nicer it would be to get vaccinated by drinking a yogurt smoothie
instead of being poked by a needle. That might someday be the case, thanks to Northwestern University researchers who developed a new oral vaccine using probiotics, which are healthy
bacteria found in dairy prod... Read More

Researchers Warn of Bacteria Found in Desserts in Mexico

A study to be published in the April issue of the American Journal of Tropical Medicine and Hygiene reports that desserts from restaurants in Mexico are likely to give patients travelers’ diarrhea, and are yet another food to avoid when visiting developing countries where sanitation may not be o...

Gene exchange common among sex-manipulating bacteria

Certain bacteria have learned to manipulate the proportion of females and males in insect populations. Now Uppsala University researchers have mapped the entire genome of a bacterium that infects a close relative of the fruit fly. The findings, published in PNAS, reveal extremely high frequencie...

New Test Could Speed Tuberculosis Results

Tuberculosis killed one million three hundred thousand people around the world in two thousand seven. In addition, almost half a million people who were infected with tuberculosis and with H.I.V. also died. Those were listed as H.I.V. deaths. Read More

Green hair bleach?

The new blond is bound to be green – that is if chemists at a Japanese beauty company have their way. New research, presented today at the American Chemical Society meeting in Salt Lake City, has uncovered an enzyme that can remove dark pigment from hair. Read More

This scientist's passion: Ending the scourge of parasitic diseases

Even as a child, Peter Hotez held a grown-up's fascination for the tiny creatures living in the creek near his house. Inspired by Paul de Kruif's Microbe Hunters, a popular book on disease detectives, Hotez persuaded his parents to buy him a microscope. He spent hours watching little animals wri... Read More

Improved Antibiotic: Genes For Synthesizing Thiostrepton Identified

Researchers at the Georgia Institute of Technology have identified the genetic machinery responsible for synthesizing thiostrepton, a powerful antibiotic produced by certain bacteria. Though effective against the dangerous MRSA (methicillin-resistant Staphylococcus aureus) and vancomycin-resista... Read More

New Enzymes Created For Biofuel Production

Researchers at the California Institute of Technology (Caltech) and world-leading gene-synthesis company DNA2.0 have taken an important step toward the development of a cost-efficient process to extract sugars from cellulose--the world's most abundant organic material and cheapest form of solar-...
