Family labels framed similarly across cultures
Despite differing languages, a trade-off between simplicity and usefulness of words defining kin relationships might be universal.

Long-acting contraceptives best by far
Implants and IUDs outperform the pill, vaginal ring and patch as birth control options, a study finds.

Severe sleep apnea tied to cancer risk
A chronic lack of oxygen caused by disrupted rest may explain the association, researchers say.

From cancer to quantum, teens’ scientific feats celebrated
Winners of the 2012 Intel ISEF show the promise of science for improving the world.

Good cholesterol may not be what keeps the heart healthy
Genetic study suggests that higher levels of HDL aren’t directly responsible for the lower risk of cardiovascular disease seen in population studies.

Redefining ‘concern’ over lead
The Centers for Disease Control and Prevention announced May 16 that it would no longer designate any particular blood-lead value in children as representing a “level of concern.” Its justification: There is no threshold below which lead exposures are not a concern.

Coffee gives jolt to life span
Unlike wine's, coffee's benefits apparently keep increasing well beyond the first two servings.
