The cholera epidemic in Haiti is just getting started. Disagreements over who, or what, was responsible for the epidemic continue, and health agencies predict the situation will get much worse before cases start falling. Yet good vaccines are going unused. New Scientist rounds up the latest news... Read More
Using X-rays, researchers have identified the structure of a key protein from Lassa virus, which infects 100,000 to 300,000 people every year in West Africa—and kills 5,000.
The structure reveals how the virus evades its host’s immune system, and how it hijacks infected cells’ vital machinery... Read More

The Hawaiian bobtail squid and its resident bacteria, Vibrio fischeri, have a powerful and still somewhat mysterious symbiotic relationship. The luminescent bacteria populate a small pouch on the squid’s underside called the light organ, and provide a sort of “Klingon cloaking device.” They prod... Read More
Merck & Co said once-daily use of its HIV drug Isentress was less effective in a late-stage study than standard twice-daily dosing among patients that had not previously been treated for the virus that causes AIDS.
Based on the disappointing initial results, the U.S. drugmaker said on Monday... Read More
A technique to keep the tips of your chromosomes healthy could reverse tissue ageing. The work, which was done in mice, is yet more evidence of a causal link between chromosome length and age-related disease.
Telomeres, the caps of DNA which protect the ends of chromosomes, shorten every time... Read More
Moselio Schaechter of Small Things Considered has authored a post about the work of Maria Dominguez-Bello of the University of Puerto Rico who has been studying Opisthocomus hoazin, a unique bird who is known to carry out a pre-gastric (ruminal) fermentation. Dominguez-Bello has been investigati... Read More
President Obama on Wednesday ordered a vast review to ensure the ethical treatment of people who take part in research backed by the federal government.
His action is a response to the revelation this year that American scientists intentionally infected people at a Guatemalan mental hospital ... Read More
Britton Chance, a biophysicist who did pioneering research on how living organisms produce and manage energy and helped develop diagnostic tools, like one for the detection of breast cancer, died on Nov. 16 in Philadelphia.
Dr. Chance, who was also a world-class yachtsman and won an Olympic ... Read More
A leading medical group says there's some evidence that probiotics, or "good" bacteria, may have limited benefits for certain illnesses in children.
But the group says the science isn't yet strong enough to advocate infant formulas containing probiotics. And probiotics shouldn't be given to c... Read More
Many urinary tract infections (UTIs) can be cleared up with a big bottle of cranberry juice, but when these infections go bad, they can be really, really bad. Uropathogenic E. coli is the leading cause of uncomplicated UTIs, and if left untreated it can proceed right up the urinary tract to the... Read More

This study at Turku University in Turku, Finland, published Tuesday in the Lancet Infectious Diseases says the 2007-08 vaccine ... Read More
Scientists are racing to develop tests for a retrovirus called XMRV, which could be used to determine if the blood supply is tainted and to assess how many people may be infected.
The impetus behind the drive is a paper published in the journal Science last year that reported a link between X... Read More
It's the stuff of doomsday movies: A new virus jumps from animals to people, with ominous possibilities.
At the California National Primate Research Center at the University of California, Davis, last year, a newly identified form of virus devastated a monkey colony and sickened a researcher,... Read More
Imagine taking a midnight stroll, your route lit by row upon row of trees glowing a ghostly blue. If work by a team of undergraduates at the University of Cambridge pans out, bioluminescent trees could one day be giving our streets this dreamlike look. The students have taken the first step on t... Read More
