Biologists' Favorite Worm Gets Viruses: Finding Means C. Elegans May Aid Studies of Human Infections

A workhorse of modern biology is sick, and scientists couldn't be happier.

Researchers at Washington University School of Medicine in St. Louis, the Jacques Monod Institute in France and Cambridge University have found that the nematode C. elegans, a millimeter-long worm used extensively for ... Read More

'Undead' May Influence Biodiversity, Greenhouse Gas Emissions

It's commonly known, at least among microbiologists, that microbes have an additional option to living or dying -- dormancy.

Dormant microbes are less like zombies and more like hibernating bears. What isn't known, however, is how large numbers of dormant microorganisms affect the natural env... Read More

Designer bacteria bug transforms glycerol

A strain of bacteria found in soil is being studied for its ability to convert glycerol - waste from the biodiesel process - into several useful materials. Keerthi Venkataramanan, a student in the University of Alabama in Huntsville's biotechnology Ph.D. program, is developing biological tools t... Read More

Some foodborne bacteria target the heart

Bacteria called Listeria monocytogenes can cause mild food-poisoning symptoms in healthy individuals, but some strains have an enhanced ability to invade the heart, a new study finds.

The ability to infect the heart, possibly causing serious heart disease, may be due to particular proteins on... Read More

Where antibiotic resistant superbugs come from: biology explained at a "3d grade reading level"

Implante writes, "I'm a TA for a first year med school class and made this module on how antibiotics have driven the development of the MRSA 'superbug' that you hear about in the news. Nothing like making a module for medical students at a 3rd grade reading level. Enjoy!"

And enjoy I did! I h... Read More

Few Students Show Proficiency in Science, Tests Show

On the most recent nationwide science test, about a third of fourth graders and a fifth of high school seniors scored at or above the proficiency level, according to results released Tuesday.

Only one or two students out of every 100 displayed the level of mastery that the federal panel gover... Read More

Researchers Warn of Tularemia in Texas Feral Hogs

Animal Farms May Produce Superbugs

Superbugs that are resistant to antibiotics, long known to create life-threatening infections in hospital patients, could also be originating from animal farms where antibiotics are used to promote growth, potentially threatening human health, new research suggests.

It's not the pigs causing ... Read More

Household bugs - a risk to human health?

Ludek Zurek and collaborators from Kansas and North Carolina State Universities isolated bacteria from farm pig feces and compared them to the bacteria present in the intestines of the house flies and German cockroaches caught on those farms.

They subjected the bacteria to a range of differe... Read More

New Method Attacks Bacterial Infections on Contact Lenses

Researchers at National Jewish Health and the University of Texas Southwestern Medical Center have discovered a new method to fight bacterial infections associated with contact lenses. The method may also have applications for bacterial infections associated with severe burns and cystic fibrosis... Read More

Research shows how pathogenic bacteria hide inside host cells

A new study into Staphylococcus aureus, the bacterium which is responsible for severe chronic infections worldwide, reveals how bacteria have developed a strategy of hiding within host cells to escape the immune system as well as many antibacterial treatments. The research, published by EMBO Mol... Read More

When a baby gets a vaccine, who reaps the benefits?

Babies in this country and in Europe are given several immunizations during the first two years of life, and one vaccine that has made a big dent in infant mortality rates is PCV7 – the 7-valent pneumococcal conjugate vaccine. A study coming out in mBio this week shows that the vaccine cuts down... Read More

The Future of Algae Fuels Is … When?
