Scientists at the University of East Anglia, Pacific Northwest National Laboratory, and Pennsylvania State University have demonstrated for the first time the mechanism by which some bacteria can transfer electrons across a membrane to the cell exterior, allowing them to "breathe" metals. These ... Read More
The "Do It Yourself" biology movement is growing among real scientists and citizen scientists in homegrown or garage-based labs around the U.S. As this NPR piece reports "they're studying things like DNA and E. coli bacteria in home laboratories. And for now, the industry is largely unregulated.... Read More
In just a few minutes, with microscopic glass tubes and a nanoliter of liquid, a team of BYU researchers can track down even the most elusive virus molecules.
The team of professors and students has created a tiny silicon microchip that traps molecules based on size, not quantity.
"The und... Read More
Vical Incorporated announced the issuance of US Patent No. 7,628,993 covering DNA vaccines for herpes simplex virus type-2 (HSV-2). HSV-2 is a sexually transmitted virus which is the leading cause of genital herpes. Vical is collaborating under a previously disclosed grant on the preclinical dev... Read More
The H1N1 flu pandemic may not be conquered until 2011 and continued vigilance is required against the virus which can still mutate, the head of the World Health Organisation said on Tuesday.
WHO Director-General Margaret Chan also warned that although countries have shored up their defences a... Read More
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
Despite the recently soured economy, venture capitalists have remained relatively optimistic about investment opportunities in the life science research tools and molecular diagnostics sectors, according to industry insiders.
In particular, the VC landscape for life science tools and molecula... Read More
The mystery started the day farmer Russ Kremer got between a jealous boar and a sow in heat.
The boar gored Kremer in the knee with a razor-sharp tusk. The burly pig farmer shrugged it off, figuring: "You pour the blood out of your boot and go on."
But Kremer's red-hot leg ballooned to dou... Read More
The New Hampshire Department of Health and Human Services (DHHS) has confirmed a case of gastrointestinal anthrax in an adult female from Strafford County. The patient is currently in critical condition. DHHS’ Division of Public Health Services (DPHS) along with the Centers for Disease Control a... Read More
A recent paper published in the New England Journal of Medicine by researchers who looked at data from the recent influenza season in the Southern Hemisphere finds that pandemic 2009 H1N1 influenza was associated with pediatric death rates that were 10 times the rates for seasonal influenza in p...

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
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
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 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.
BRAC health programme executive Dr Fahim Ahmed Chowdhury however said there is a silver lining that though such large number of people are ... Read More
Frustrated by responses to his research, 33-year-old Barry Marshall, MBBS, ingested Helicobacter pylori one day in 1984, and soon developed stomach pain, nausea, and vomiting: all signs of the gastritis he had intended to induce.
"I didn't actually expect to become as ill as I did," he wrote ... Read More
One day, towards the end of summer, I walked into my living room and found my cats playing "Secret CIA Prison" with a bat. He was alive, but just barely. 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
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
In the 1967 film "The Graduate," Mr. McGuire advises protagonist Ben Braddock, "There's a great future in plastics." A handful of recent UC Davis graduates have heeded that advice and are building the next generation of plastic.
Their company, Micromidas, processes sewage sludge, the hardened... Read More
