Some people are genetically programmed to need less sleep than the rest of us, according to a new paper published this week in Science. A rare genetic mutation lets its carriers function happily and healthily even with hours less sleep each night than doctors normally recommend.
Researchers discovered the enviable gene variant …
Cancer death rates have fallen steadily in the U.S. since the 1950s, a new paper in Cancer Research reveals. Kids and young adults were the first to see a big drop, but now the gains are felt by adults of all ages, the study reports.
If this sounds like a typical news flash that contradicts what you just read yesterday, it’s only …
You may have seen the recent (and well–publicized) study that shows redheads are more scared of the dentist than other people are. The idea is that the same gene variant that leads to red hair also — for some reason — makes people more susceptible to pain, and less receptive to the common anesthetics that a dentist might use before …
The White House isn’t happy with a new poster ad in DC metro stations, according to the Washington Post. The ad depicts an eight-year-old girl with the speech bubble, “President Obama’s daughters get healthy school lunches. Why don’t I?”
The poster comes from the non-profit Physicians Committee for Responsible Medicine (PCRM), a group …
While domestic responsibilities are slowly being divvied up more equally among men and women with the increasing prevalence of working moms and stay-at-home dads, there is plenty of evidence suggesting that women still shoulder most of the household and child-rearing responsibilities. A study highlighted by the Economist earlier this …
Most people grossly overestimate the benefits of cancer screening, according to a new survey of 10,228 Europeans. A whopping 92% of women believe the life-expectancy benefit from breast-cancer screening is at least ten times bigger than it really is, or say that they don’t know how much benefit screening provides. (On average …
Follow four simple rules and you could reduce your chronic-disease risk by as much as 80%, according to a new study in the Archives of Internal Medicine. The golden lifestyle rules: never smoking, maintaining a healthy body weight, exercising regularly, and eating a balanced diet.
Sounds simple? It is — and yet only 9% of the nearly …
Optimists outlive pessimists, a new study shows. Of nearly 100,000 women enrolled in the Women’s Health Initiative, those who gave optimistic answers on a personality test were 9% less likely to develop heart disease within eight years — and 14% less likely to die — than women who got low optimism scores on the test.
TIME’s Alice …
Women who breastfeed appear to have lower risk of developing pre-menopausal breast cancer than those who don’t, according to a new study released today in in the Archives of Internal Medicine. The stats are especially compelling for women with a family history of the disease. Among that group, women in the study who’d breastfed had just …
Scientists have found a way to manipulate the neurons in mice that respond to itch — and, in the process, have settled a longstanding debate: Is itchiness just a form of pain, or a separate, unique sensation?
It turns out the brain treats itch and pain completely differently, even though they can both be excruciating.
A common back-pain surgery works no better than a faked surgical procedure, according to a study released today in the New England Journal of Medicine. But the setback for the treatment may raise new questions about what really …
You’d be surprised. There’s a difference between preventing sunburn and preventing other types of skin damage. Some sunscreens can do both, but others can’t.
Recently I wrote an article for TIME about the struggle between parents and pediatricians when a child is too heavy. Many well-intentioned parents, it seems, don’t recognize signs that their own kid is overweight, especially when the child is still young (say, before adolescence). This parental ignorance may itself be because a …
