    The nose knows how to fight staph

    MANCHESTER, England — The human nose harbors not only a deadly enemy — Staphylococcus aureus — but also its natural foe. Scientists have now isolated a compound from that foe that might combat MRSA, the methicillin-resistant strain of S. aureus.

    “We didn’t expect to find this. We were...

    Vaping’s toxic vapors come mainly from e-liquid solvents

    Over the last three years, growing evidence has shown that electronic cigarettes are not the harmless alternative to smoking that many proponents have argued. Now, a new study traces a large share of e-cigs’ toxic gases to a heat-triggered breakdown of the liquids used to create the vapors. And the hotter an e-cig gets — and the more it’s used — the more toxic compounds it emits, the study...

    Iron-loving elements tell stories of Earth’s history

    View the slideshow

    Four and a half billion years ago, after Earth’s fiery birth, the infant planet began to radically reshape itself, separating into distinct layers. Metals — mostly iron with a bit of nickel — fell toward the center to form a core. The growing core also vacuumed up other metallic elements, such as platinum, iridium and gold.

    By the time...

    Neonicotinoids are partial contraceptives for male honeybees

    Pollen tainted with neonicotinoid pesticides could interfere with male honeybee reproduction, a new study finds.

    After bee colonies fed on pollen spiked with the pesticides thiamethoxam and clothianidin, male bees, or drones, produced almost 40 percent fewer living sperm than did males from colonies...

    Sea ice algae drive the Arctic food web

    As happens every summer, sea ice in the Arctic is shrinking as temperatures warm. But this year is a particularly warm year, and there is less sea ice than there usually is. Scientists say Earth is on track to matchor perhaps even exceed the record low extent of summertime sea ice seen in...

    Dolly the Sheep’s cloned sisters aging gracefully

    Clones don’t age prematurely, new research on Dolly the Sheep’s sisters suggests.

    Researchers and animal welfare activists have been concerned that cloning, or somatic cell nuclear transfer, could cause health problems in cloned animals. Instead, a study of 13 cloned sheep found no signs of early aging or other health...

    To prevent cannibalism, bring chocolate

    Here’s another reason to show up with a box of chocolates: It doubles as a shield if she bites.

    Edging slowly toward a female, male nursery web spiders clutch in front of their bodies their version of courtship candy: a big dead insect wrapped in white silk. “It’s pretty spectacular actually,” says Søren Toft of Denmark’s Aarhus University. It’s also prudent, he and colleague Maria Albo...

    Website tests predictive powers of the hive mind

    As the saying goes, “It’s difficult to make predictions, especially about the future.” The website aims to make this challenging task easier by harnessing collective wisdom.

    Metaculus solicits answers to questions about the future — on topics spanning science, politics and economics — and combines these predictions to infer the likely...
