The apparently random self-assembly of molecular threads into the proteins that make the body work is far less frantic than previously thought, Michigan State University scientists say. That discovery could be a key to help unlock the nature of some diseases.
How proteins spontaneously “fold”... Read More

Stem cell therapy has proven successful in treating a lethal skin disease affecting children, according to a new international study.
Researchers for the first time have used stem cells from bone marrow to repair the skin of patients with recessive dystrophic epidermolysis bullosa, or RDEB, s... Read More
When it’s made by the stomach ulcer-causing bacterium Helicobacter pylori. A study just released by mBio reveals that the enzymes that synthesize vitamin B6 are important virulence factors for this pathogen, possibly because of the role vitamin B6 plays in building fully-functioning flagella to...

A new bacteria that has emerged in India — dubbed NDM-1 and which is resistant to even the strongest antibiotics — is quickly spreading worldwide, British researchers say in a report published in the medical journal The Lancet. Click "source " to watch the video. Read More
Researchers at Rice University have won federal support to develop a genomic test that can quickly determine whether a disease outbreak is caused by a natural pathogen or one that was grown in a lab by terrorists.
The three-year grant—Rice's first from the Defense Threat Reduction Agency—is d... Read More
Now that older people have prescription drug coverage from Medicare, they are using more antibiotics, a new study has found.
That may not sound surprising. But the authors of the study say it could be worrisome.
Among the drugs being taken more often, the researchers pointed out, are new ... Read More
For four weeks, my 11-year-old daughter has been coughing. It is not your run-of-the-mill summer cold, but a violent, debilitating cough that takes over her body, usually at night.
During these fits, her face turns red, and tears start streaming from her eyes. She coughs so hard she eventuall... Read More
The Malaysian Institute of Medical Research (IMR) is coordinating bacteria surveillance for the New Delhi Metallo-beta-lactamase (NDM-1) gene, which makes bacteria resistant to almost all antibiotics and thus turning them into “Superbugs”.
Health Director-General Tan Sri Dr Mohd Ismail Merica... Read More
Louisiana's agriculture department says Veron Foods LLC of Prairieville is recalling 250 tons of ready-to-eat sausage and hog's head cheese because of possible contamination by bacteria.

Hot nights are accelerating panicle blight, a seed-borne bacterial rice disease that can cut yields by up to 60 bushels per acre.
The rod-shaped bacteria responsible for panicle blight destroy or rot the developing rice grains, resulting in what’s known as kernel blanking, or partial blanking... Read More
Building on an enzyme found in nature, researchers at Rensselaer Polytechnic Institute have created a nanoscale coating for surgical equipment, hospital walls, and other surfaces which safely eradicates methicillin resistant Staphylococcus aureus (MRSA), the bacteria responsible for antibiotic r...

It was hard enough for health officials to track down the source of the original outbreak of Legionnaires' disease, at the old Bellevue Stratford Hotel in Philadelphia, in 1976.
Imagine if the disease had been caused by a moving target.
That's what happened last year in southeastern Spain,... Read More
At first glance, the Christmas Atoll south of Hawaii seems to be a tropical paradise.
That may be true above the waterline, but explorations of the surrounding seas by San Diego-based researchers found corals were dead or diseased, sharks and other large predators were scarce and only small ... Read More
Whether or not ecological disaster follows the BP spill may hinge on what eats the oil first.
"Right now it's a race between the microbes and the fish," said marine biologist Larry McKinney of Texas A&M University, a specialist in the Gulf of Mexico.
Ideally, microbes will win, transformin... Read More
Two recent studies provide evidence for a new approach to vaccines to prevent infections caused by drug-resistant Staphylococcus aureus -- better known as MRSA – the leading cause of skin and soft tissue, bloodstream and lung infections in the United States. One demonstrates a way to counteract... Read More
The bacterium Helicobacter pylori, which lives in the human stomach and is associated with ulcers and gastric cancer, is shaped like a corkscrew, or helix. For years researchers have hypothesized that the bacterium's twisty shape is what enables it to survive -- and thrive -- within the stomach'... Read More
By now many people will be aware of one of this week's topics of conversation, the emergence of the resistance determinant New Delhi metallo-β-lactamase 1 (or NDM-1), which is an enzyme that confers resistance to a group of very useful antibiotics, the carbapenems; it does this by cleaving the a...
