U.S. scientists say bacteria in six large arctic river ecosystems might be used as markers for monitoring climate change in the polar region.
Researchers at the University of Maryland's Horn Point Laboratory said their study of bacterial communities in the ecosystems reveals predictable tempo... Read More
Research into Alzheimer's disease seems an unlikely approach to yield a better way to fight urinary tract infections (UTIs), but that's what scientists at Washington University School of Medicine in St. Louis and elsewhere recently reported.
One element links the disparate areas of research: ... Read More
The International Association of Synthetic Biology announced that it has finalized its code of conduct for gene synthesis, covering ethics, biosafety, and biosecurity aspects of gene synthesis.
The code of conduct put forth by the European group follows the establishment last week of an inter... Read More
Scientists have crystallised a protein that may help gut bacteria bind to the gastrointestinal tract. The protein could be used by probiotic producers to identify strains that are likely to be of real benefit to people.
"Probiotics need to interact with cells lining the gut to have a benefici... Read More
Federal health officials are trying to shift supplies of the seasonal flu vaccine away from chain pharmacies and supermarkets to nursing homes, hoping to counter a shortage that threatens to cause a wave of deaths this winter among the nation’s most vulnerable population.
The extent of the sh... Read More
A leading association of clinicians on Monday accused an "anti-vaccination movement" of breeding suspicion about the (A)H1N1 swine flu vaccine in Europe and declared public health and lives were at risk.

Cases of a drug-resistant bacterial infection known as MRSA have risen by 90 percent since 1999, and they are increasingly being acquired outside hospitals, researchers reported on Tuesday.
They found two new strains of methicillin-resistant Staphylococcus aureus -- MRSA for short -- were cir... Read More
As the festival of mandatory gratitude looms into view, allow me to offer a few suggestions on what, exactly, you should be thankful for.
Be thankful that, on at least one occasion, your mother did not fend off your father with a pair of nunchucks, but instead allowed enough contact to facili... Read More
Current research suggests that a common oral bacterium may exacerbate autoimmune disease. Multiple sclerosis (MS), a disease where the immune system attacks the brain and spinal cord, affects nearly 1 in 700 people in the United States. Patients with multiple sclerosis have a variety of neurolog... Read More
Scientists in the US have discovered a new class of biological antifreeze molecules - the first that do not contain proteins. The antifreeze, extracted from an Alaskan beetle capable of surviving at -60°C, consists of linked mannopyranose and xylopyranose sugars, termed xylomannan, associated wi... Read More
To improve science and mathematics education for American children, the White House is recruiting Elmo and Big Bird, video game programmers and thousands of scientists.
President Obama will announce a campaign Monday to enlist companies and nonprofit groups to spend money, time and volunteer ... Read More
AN HIV virus modified to infect monkeys could be a big step forward for HIV research.
The disclosure last month that an experimental vaccine against HIV may not be as effective as first thought highlighted a nagging problem with HIV-vaccine research: that there is no effective way of testing ... Read More
Bacteria possess an ingenious mechanism for preventing oxygen from harming the building blocks of the cell. This is the new finding of a team of biologists that includes Joris Messens of VIB, a life sciences research institute in Flanders, Belgium, connected to the Vrije Universiteit Brussel. Th...

Back in 1885, a German-Austrian pediatrician by the name of Theodor Escherich was investigating an unusually high incidence of infant mortality due to severe diarrhea. Using the newer, more powerful microscopes, he soon isolated a rod shaped bacteria derived from a residue best left unmentioned.... Read More
No matter how much yogurt we eat or kambucha we drink, no matter how much we hear about how bacteria can be beneficial to us, it still can seem creepy that there are up to 1,000 species of bacteria and fungi lounging around on our skin at any given time--1 trillion or so microscopic residents.

"Malaria that is resistant to the best available drug is more widespread in Southeast Asia than previously reported, new research shows. The worrisome finding poses a risk that travelers could carry this strain of the malaria parasite to other parts of the globe and unwittingly spread it, scient... Read More
Analysis of all complete genome sequences of the pandemic influenza A(H1N1)v virus available as of 10 September 2009 revealed that two closely related but distinct clusters were circulating in most of the affected countries at the same time. The characteristic differences are located in genes en... Read More
"Four pilgrims have died of swine flu as they take part in this year's annual Mecca pilgrimage, Saudi officials say.
