Hand sanitizers claiming to kill 99.9 per cent of germs actually kill far fewer in real-world conditions, a University of Ottawa microbiologist has found.
While sanitizers may indeed kill nearly all the germs in lab conditions, in ordinary life they're second-best to soap and water, a new stu... Read More

Researchers at Newcastle, U.K.-based Northumbria University are collaborating with Nonlinear Dynamics Ltd., a company that develops proteomics analysis software, on a project that may have important implications for the production of cellulosic biofuels. During the three-year project, researcher... Read More
The hamburger you buy at McDonald's may look just like the hamburger you cook at home.
But, in terms of safety, the two burgers are not close. Not unless you buy your own meat directly from a packing plant that you'd not only inspected yourself but was also inspected by a third party. And you... Read More
It's not everywhere that you can get raw milk from a vending machine, or see how cheese tastes when it’s made without any added salt (pretty bad) or when it’s aged after being sewn up in a sheepskin, wool side in (like a wet sweater).
I sampled many lactic curiosities this October in Bra, a s... Read More
Last year, in the United States, there were 65,000 deaths caused by various strains of drug resistant bacteria, or superbugs. That is more than the combined number of deaths from prostate and breast cancer. Hog farmer, Russ Kremer, was almost another victim.
Russ was gored by an amorous boar,... Read More
The Associated Press is reporting that National Steak and Poultry is voluntarily recalling 248,000 pounds of beef it said might be contaminated with a strain of E. coli bacteria. NS&P said the meat could be linked to illnesses in six states. Click "source" for more. Read More
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
