April 2, 2012 Foul-smelling urine in a very young child who is fussy or feverish could point to a urinary tract infection, a study by Canadian doctors finds. This might help doctors decide whether to collect a urine sample, when doing so might require an invasive procedure.
March 30, 2012 A government advisory committee has reconsidered its advice to keep certain details of bird flu experiments secret. Revised versions of manuscripts that describe two recent studies can be openly published, the committee now says. The decision could help end a debate that has raged within the scientific community for months.
March 29, 2012 The human brain may be just three pounds of jelly. But it turns out that jelly is very organized. New scanning techniques show that the brain's communications pathways are laid out in a highly ordered three-dimensional grid that look a bit like a map of Manhattan.
March 21, 2012 People sometimes take prescription drugs to keep from getting sick at high altitudes. But medical researchers wondered whether ibuprofen, the painkilling mainstay, would be an effective over-the-counter alternative. The results look promising.
March 16, 2012 Researchers made a bunch of male fruit flies into boozehounds by pushing them on females unreceptive to their advances. The experiments showed that a brain chemical, very much like one in humans, played a key role in determining their behavior.
March 14, 2012 A single statistic can help show how beneficial, or not, a treatment is. It's called the number needed to treat. And the lower it is, the better.
March 14, 2012 Saturated fat, the stuff in meat and dairy foods, was associated with lower sperm counts, in a study of 99 men who were clients of fertility clinics. The results, though preliminary, suggest there's something men can do to boost the odds their sperm are up to their evolutionary task: eat better.
March 7, 2012 Scientists at the Food and Drug Administration are feeling more optimistic about the future of their agency than they were back in 2006, according to a survey just out from the Union of Concerned Scientists. But they still report concerns about outside pressures on the agency's decisions and policies.
March 5, 2012 Why are politicians and those of us who vote for them so obsessed with inconsistency? We take that question on from three angles: how our brains are wired; the psychology of judging what's consistent; and how consistency plays out in leadership styles.
March 2, 2012 There's no cure for Ebola. But a group of scientists is exploring whether some drugs already approved to treat cancer might help tame the virus. Sounds wild. But there's a reason to think it might work.
February 22, 2012 Psychiatrists have long claimed that gardens hold healing powers for mental illness. Now, scientists are exploring a new field called horticultural therapy for everyone from troubled youth to veterans. But just how gardens affect the brain remains mainly a mystery.
February 17, 2012 A small group has gathered at the World Health Organization in Geneva to discuss a controversy over experiments that generated genetically altered viruses. After the meeting, which ends Friday, the WHO will announce what happened behind closed doors.
February 16, 2012 The highly-anticipated gathering of flu experts has been described as a fact-finding session that will focus on understanding how bird flu studies done at Erasmus Medical Center in the Netherlands and at the University of Wisconsin were performed and overseen by the relevant authorities.
February 15, 2012 Scientists working with bird flu recently called a 60-day halt on some controversial experiments. The unusual move has been compared to a famous moratorium on genetic engineering in the 1970s. Key scientists involved in that pause on genetic research disagree on whether today's furor over bird flu is history repeating itself.
February 14, 2012 The science may not be perfect, but a prominent sleep researcher says she and her colleagues have a pretty good handle on how much sleep kids need. She defends the field against a study that claimed the experts haven't even had a clue.
