April 29, 2013 People crave explanations that are simple, broad, elegant. But the prettiest, most satisfying explanations aren't always the best explanations, as the dark story of Dutch social psychologist Diederik Stapel makes clear.
April 26, 2013 Scientists have deployed hundreds of tiny, experimental robots to help with biopsies. They're as small as a speck of dust. They look like tiny ninja throwing stars. And researchers use magnets to retrieve them.
April 26, 2013 An oversight committee halted a big clinical study of an experimental HIV vaccine after a peek at preliminary results showed there was no way the study would be able show the vaccine works. More vaccinated people became infected with HIV than those who got placebo shots.
April 25, 2013 When researchers turned on a gene for the hormone in the livers of diabetic lab mice, the number of insulin-making cells in their pancreas glands tripled within 10 days. Although the research was conducted in animals, the scientists say the findings could be relevant for humans.
April 25, 2013 When Superstorm Sandy flooded lower Manhattan last year, thousands of lab animals drowned and many scientists lost months or even years of work. The specialty animals can be very difficult to replace, but researchers say the loss of animal life is emotionally devastating and difficult to get over.
April 17, 2013 Research in mice suggests that short-term hearing loss caused by loud noise like rock concerts may protect ears from more serious damage. But adapting to noise can be dangerous if you compensate by turning up the volume even higher, researchers warn.
April 11, 2013 A prominent male chin, thought to be a marker for virility, is one of the characteristics that's part of the so-called universal facial attractiveness hypothesis. But a look at chins from around the world raises doubts.
April 11, 2013 Researchers say they can measure how much pain someone is experiencing and even watch as prescription painkillers relieve it. The scanning technique could help doctors treat pain better, but the work is also fraught with questions about how the technology could interfere with the relationship between doctors and patients.
April 10, 2013 Infants received different levels of oxygen to see which was better at preventing blindness without increasing the risk of nerve damage or death. But the federal government says doctors in the study didn't tell parents enough in advance about the "foreseeable risks" to their children.
March 8, 2013 Neurosurgeons are testing whether electrodes implanted deep inside a patient's brain could help treat chronic anorexia. Doctors are searching for something to help in these hard cases, and a small experiment, with just a half-dozen women, is drawing attention.
March 7, 2013 For more than a century, neurons have been the superstars of the brain. Now researchers say that when they placed human versions of another type of brain cell into mice brains, the mice grew up to be faster learners. This supports the hypothesis that these glial cells — and not just better-known neurons — play an important role in learning.
March 4, 2013 More than 90 clinical trials have tested therapeutic vaccines in cancer patients, but the results have been a mixed bag. A recent study in mice suggests that changing a traditional ingredient in the vaccines could make a big difference.
February 28, 2013 Want to be a better surgeon? Get your game face on. A study finds that surgical residents who played video games for an hour a day performed better at simulated keyhole surgeries than colleagues who refrained.
