Aphids can be a gardener’s nightmare. But they may be an evolutionary biologist’s dream. Because they’re pioneers in the history of life on Earth. For one thing, they’re now the only known animals to produce the chemical pigments called carotenoids, which help in cell repair and immunity. It’s t... Read More
The Geobacter bacterium could be the biofuel-generating machine of the future, producing energy-rich butanol costing as little as $2 per gallon.
A project seeking to accomplish this, headed by Derek Lovley and colleagues at the University of Massachusetts, Amherst , received $1 million in fun... Read More
Organizers of the XVIII International AIDS Conference (AIDS 2010) announced today that President Bill Clinton, founder of the William J. Clinton Foundation and 42nd President of the United States, and South African Health Minister Aaron Motsoaledi will be among 19 high-level speakers who will ad... Read More
A new improved modeling system, developed by Chinese researchers, which attempts to incorporate more of the virus’ random behavioral dynamics, suggests that a particular type of T cell could be useful in the development of an AIDS vaccine.
New research published in New Journal of Physics (co-... Read More
Hans Martin, professor emeritus, Technical University Darmstadt, Germany, reflects on the mysteries of L-forms, strains of bacteria that lack cell walls.
"L-forms are bacterial variants with defective cell walls and irregular growth and multiplication. They arise after peptidoglyc... Read More
A two-week course of the antibiotic rifaximin can provide long-lasting relief for patients with irritable bowel syndrome characterized by diarrhea and bloating, researchers from Cedars-Sinai Medical Center reported Monday at a New Orleans meeting during what is known as Digestive Diseases Week. ...

As a person whose suffered mult. fractures (toes, fingers, thumb - that was a tough one, foot, wrist, etc.) due to various sports & other injuries, I can personally attest to the value inherent in this discovery.
While I'm not looking forward to my next break, hoping this compound will be aroun... Read More
The researchers used cryo-electron microscopy to image a virus structure at a resolution high enough to effectively "see" atoms, the first published instance of a virus image at such a resolution. Read More
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
