Frisky bacteria war on drugs revealed

Antibiotics are met by resistance from germs; so researchers develop new drugs and germs become resistant again.

Now some scientists believe genetics will be the new weapon in the fight, with doctors consulting bacterial genomes when treating disease.

This week a team at the Wellcome Trust... Read More

New research on honeybee illness

Ecologist Colin Henderson co-authored a study that may have identified the cause of the honeybee illness that has plagued U.S. bees since 2006. Henderson, 59, is an associate professor of biology at the University of Montana. He and colleagues there found a correlation between colony collapse di... Read More

Directed Evolution: E. coli gets off the couch, becomes an extremophile

Can you create an extremophile? The microbes living and thriving at the fringes of the biosphere manage to get by in spite of extreme temperatures, radiation levels, and pressures (did I miss any?) that most other life forms would choke on. But how easy would it be for an organism that prosper... Read More

Bacteria Possible Cause of Preterm Births

The type of bacteria that colonize the placenta during pregnancy could be associated with preterm birth and other developmental problems in newborns according to research published in the current issue of the online journal mBio®.

"The fetal inflammatory response appears to contribute to the ... Read More

Obama's call for innovation follows slowdown in most sectors, scholars say

Google and the iPhone are American inventions. But the first mass-produced gas-electric hybrid car was made in Japan.

And although the United States now fosters a nascent commercial space industry, if you want to speed from city to city on a smooth, fast train, you have to head to Europe.

Researchers warn against kissing pets

They give you joy. They give you loyalty. They give you sloppy kisses.

But before you allow Fido or Fluffy to climb into bed with you at night, as an increasing number of Americans are doing, know that they can also give you something else: zoonoses.

In the United States, the most common p... Read More

Pneumonia drugs helped evolve a superbug

Sometimes natural selection gets a helping hand from humans. A new study tracing the genetic history of a nasty strain of pneumonia-causing bacteria shows that antibiotics and vaccines helped shape the microbe’s evolution.

In a technical tour de force, an international team of researchers dec... Read More

Something to Chew on: Researchers Look Inside Cow Stomachs for a Leg up on Next-Gen Biofuels

You may have heard the proclamation before: The next generation of biofuels will be derived from cellulosic plant material. And, in theory, this makes sense. Whereas ethanol can be produced via the fermentation of simple sugars in food crops such as corn or sugarcane, it would be more economical... Read More

The Salmonella Index: The Best and Worst States for Food Poisoning

As last year's Salmonella outbreak and the unethical practices of egg mogul Jack DeCoster proved, our food supply is not always as safe as expected. One problem is that numerous systems exist for reporting foodborne illnesses on a state by state basis, and the difficulty of analyzing the data ma... Read More

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

After finding evidence in feral hogs of the bacteria that causes tularemia, researchers at The Institute of Environmental and Human Health (TIEHH) at Texas Tech University are warning hunters and ranchers to use caution when handling wild game.

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.
