January 20, 2012 Scientists working with a highly contagious, lab-created strain of bird flu will suspend their research for 60 days. The pause will make possible an international debate on the merits of the work, they say.
January 20, 2012 Each tear you shed contains an army of enzymatic Pac-Men, ready to chase down and gobble up germs before they infect the sensitive tissues around your eye. Now scientists have found just one molecule of the germ-fighting enzyme is a potent defender.
January 12, 2012 After a three-year investigation, the University of Connecticut Health Center has told 11 scientific journals that studies they published by resveratrol researcher Dipak K. Das may not be trustworthy.
January 6, 2012 The vaccine protected 80 percent of monkeys from infection with SIV, the simian version of HIV. By comparison, an experimental HIV vaccine was 31 percent effective in protecting people against infection in a large-scale study unveiled in 2009.
December 29, 2011 Surgeons make full-face transplants a reality for people with severely disfigured faces. Three such operations were performed successfully in Boston this year, a turning point in the field.
December 22, 2011 The journal Science has withdrawn a study from 2009 that suggested an obscure virus causes chronic fatigue syndrome. The findings raised patients' hopes for effective treatments. But scientists who raced to confirm the viral link failed to do so.
December 6, 2011 Bedbugs' eagerness to mate with their kin is one reason their populations have taken off so dramatically, new research suggests. Inbreeding comes naturally to them, and it doesn't seem to hurt their offspring much, as is the case with most other creatures.
November 17, 2011 At a recent conference, a Dutch scientist said he'd made bird flu virus highly contagious between ferrets — the animal model used to study human flu infection. Just five mutations did the trick. Security experts fear publishing the work could spur development of new weapons.
November 10, 2011 The drug, given by injection, isn't going to be on pharmacy shelves anytime soon. But it has now been seen to work in five different species — from mice to monkeys. A human test of the drug is set to begin soon.
October 27, 2011 Willpower will only take you so far, in case you haven't run that experiment yourself. Turns out our bodies have a fuel gauge, not entirely unlike the gas gauge in our cars, that tell us when it's time to tank up on food. Dieting can make the gauge go haywire.
October 21, 2011 Contrary to what you may have heard, more Facebook friends hasn't been proved to make your brain bigger. Check out what researchers actually found in a new study.
October 20, 2011 Teen drivers have fewer accidents as they gain experience. But that doesn't mean they are cutting down on dangerous habits like taking sharp turns and braking quickly, research shows.
