The indifference of some mosquitoes to a common insect repellent is due to an easily inherited genetic trait that can be rapidly evolved by later generations, a new study suggests.
By selective breeding, James Logan and colleagues at Rothamsted Research in Harpenden, UK, created strains of Ae... Read More
A bacterial pathogen can communicate with yeast to block the development of drug-resistant yeast infections, say Irish scientists writing in the May issue of Microbiology. The research could be a step towards new strategies to prevent hospital-acquired infections associated with medical implants... Read More
A North Carolina State University researcher has discovered that bacteria transmitted by fleas -- and potentially ticks -- can be passed to human babies by the mother, causing chronic infections and raising the possibility of bacterially induced birth defects. Read More
On May 4, the Pew Campaign on Human Health and Industrial Farming, in collaboration with Senator Dianne Feinstein (D-Calif.), Representative Louise Slaughter (D-N.Y.) and Representative Howard Berman (D-Calif.), will host Capitol Hill briefings on Denmarks experience in ending the routine use o...

Experts say there's good evidence that probiotics can help people with irritable bowel, diarrhea, and urinary tract infections and emerging research suggests that probiotics may ease symptoms of allergies (both food and respiratory) and boost the immune system.
But as often happens in the Uni... Read More
The Wall Street Journal has an amusing article out on bakers and their relationship with "starters."
"Happy is no ordinary pet. He is a sourdough "starter"—a blob of wet flour, colonized by yeast and bacteria—that lives on her kitchen counter. Home bakers increasingly are using starters, whi... Read More

Almost two weeks after the disaster started, the Deepwater Horizon in the Gulf of Mexico is still gushing up to 10,000 barrels of oil into the ocean every day. Efforts by BP and the US government to stop leakage have come up with empty hands, however it turns out one of the keys to cleanup might... Read More
Sepsis is a highly dangerous - very often lethal - inflammatory condition caused by the body's response to microbes in the blood, lungs, or other areas. Even with ICU treatment involving antibiotics & fluids in large doses, 20-35% of patients suffering from severe sepsis die inside 30 days. 40... Read More
While there are many more methods to choose from for cleaning up your RNA or DNA than there used to be, sometimes Phenol/Chloroform extraction is still the best way to go. Here I’ll discuss some of the practical aspects of using this technique.
Nick introduced the topic of Phenol/Chloroform e... Read More
Aided by a new experimental model, scientists are a step closer to understanding how cystic fibrosis (CF) causes lung disease in people with the condition. The findings, published online April 28 in the journal Science Translational Medicine, could help improve treatments for lung disease, which... Read More
A team of international researchers has brought the primary component of mammoth blood back to life using ancient DNA preserved in bones from Siberian specimens 25,000 to 43,000 years old.
Studies of recreated mammoth haemoglobin, published today (Monday 3 May) in Nature Genetics, reveal spec... Read More
Nestlé has shut down a production line after a positive salmonella test on a batch of chocolate morsels at its one of its facilities in the US, for the second time this year.
Nestlé spokeswoman Laurie MacDonald told the Journal Times that that none of the contaminated morsels left the Burling... Read More
Dr. Laurie Connell, of the University of Maine, is involved in a number of research projects spanning from the development of field detection instruments for the detrimental potato wart, to the analysis of paralytic shellfish toxins, to the extreme microbial habitats at the southern most region ...

Normally, animals get their DNA from their parents. But a new study shows that they can also get genes from another species. In fact, animals can even take genes from creatures outside of the animal kingdom — like from fungi. And that's pretty surprising.
"The idea that animals picked up DNA... Read More

There's no way to stop oily water from reaching land along the Gulf Coast, but experts will use tools both massive and microscopic to clean it up.
Oil-soaked sand on beaches in the eastern Gulf Coast can be scooped up with heavy equipment, but the grassy marshes in the Mississippi Delta can't... Read More
A multimillion-dollar research project involving the University of Nevada, Las Vegas, could help better protect U.S. troops. But it is also expected to shore up the Las Vegas area against epidemics and bioterrorism.
UNLV Associate Professor Chris Cochran is helping lead the effort and hopes i... Read More
