Molecular Chaperone Keeps Bacterial Proteins from Slow-Dancing to Destruction

Just like teenagers at a prom, proteins are tended by chaperones whose job it is to prevent unwanted interactions among immature clients. And at the molecular level, just as at the high school gym level, it's a job that usually requires a lot of energy.

In new research, scientists at the Univ... Read More

Researchers revisit old ideas in the war on cancer

Instead just studying cancer itself, more and more researchers are taking into consideration the role of the cellular environment in the development of the disease.

"Some researchers are taking a fresh look at ideas that were dismissed as folklore — a blow to the breast might spur cancer, an... Read More

Zinc fingers could open the door for gene therapy

At the University of Pennsylvania, Dr. Carl June and colleagues are using a new genetic editing technique to disrupt a gene in patients’ T cells, the type attacked by the AIDS virus, that some hope may revive gene therapy. The technique, which depends on natural agents called zinc fingers, overc... Read More

Cataloging the Diversity of Earth's Microbes

The Joint Genome Institute at the Energy Department has started what it calls a “genomic encyclopedia,” a collection of genomes from diverse microbes. Using an evolutionary approach that differs in strategy from how scientists originally chose organisms for sequencing, researchers hope to discov... Read More

Half of Bangladesh adults are TB carriers: report

Half of the adult population of Bangladesh are TB carriers but most of them are probably not aware of it as the germ remains dormant, a BRAC report said.

He lay on my floor twitching, his wings torn to Swiss cheese. The cats looked up at me as if to say, "We do good work, yes?" I locked them in ... Read More

2009 in review: H1N1 pandemic tops our list of health stories

Global health experts worried that if the virus began spreading from person to person, it could spark a human chain of infection and death worse than anything seen since 1918. They ramped up flu surveillance and bolstered vaccine production. No one predicted that the next pandemic would be launc... Read More

Their company, Micromidas, processes sewage sludge, the hardened... Read More

Researchers study microbes in cattle to unlock metabolic disease mysteries

Switching from warm-season grasses to cool-season forages can give livestock a belly ache, in some cases a deadly one, according to Texas AgriLife Research scientists.
Dr. Bill Pinchak, Texas AgriLife Research animal nutritionist at Vernon, is leading a team of scientists who are using state-of... Read More

California health officials urge pregnant women with flu-like symptoms to seek prompt antiviral treatment

A new study by California health officials says pregnant women with flu-like symptoms should promptly undergo “aggressive antiviral treatment,” even if a preliminary test shows that the patient tests negative for the flu.
