    Everest could lose most of its ice by 2100

    Glaciers around the tallest mountain in the world may reach a historic new low relatively soon.

    Combining projections of future climate with simulations of how glaciers melt and grow, researchers estimate May 27 in The Cryosphere that the Everest region of the Himalayas could lose 73 to 96 percent of its ice...

    NASA picks nine instruments for future mission to Europa

    NASA is gearing up to see what’s lurking in the salty seas beneath the icy shell of Jupiter’s moon Europa. Nine instruments will fly aboard a spacecraft slated to launch sometime in the 2020s that will investigate whether or not the moon is habitable, space agency officials...

    White House hits pause on editing human germline cells

    The United States will hold off, for now, on clinical experiments that could alter the human germ line. John Holdren, director of the White House Office of Science and Technology Policy issued a statement on May 26...

    Diet and nutrition is more complex than a simple sugar

    When it comes to studying the vast complexity of the food we eat, it helps to simplify. Test one nutrient or variable at a time to find out how each functions. Compare one part of a sugar molecule against another. These studies can tell us a great deal about how specific nutrients are processed in the body, and how they affect our health, our waistlines and even our behavior.

    But one...

    Genes and environment balance each other

    Combatants in the age-old battle of nature versus nurture may finally be able to lay down their arms. On average, both nature and nurture contribute roughly equally to determining human traits.

    Researchers compiled data from half a century’s worth of studies on more than 14 million pairs of twins. The researchers measured heritability — the amount of variation in a characteristic that...

    Brightest galaxy discovered

    The most luminous known galaxy blasts out as much light as roughly 350 trillion suns, researchers report in the June 1 Astrophysical Journal.

    A supermassive black hole lurking in the galaxy’s core probably powers this cosmic beacon, Chao-Wei Tsai, an astronomer at NASA’s Jet Propulsion Laboratory in Pasadena,...

    Ebola gatekeeper protein identified

    View the video

    Ebola relies on a molecular “inside man” to sneak into cells.

    Mice lacking the virus’s accomplice, a protein called NPC1, are completely protected from Ebola infection, scientists report May 26 in mBio. Designing drugs that target NPC1 could potentially stop Ebola from breaking and...

    Next icy era may be on hold

    The next big chill may be overdue. If humans hadn’t boosted levels of atmospheric carbon dioxide, Earth’s next frosty bout of glacial growth probably would have already started, new research suggests.

    For the last 11,700 years, Earth has been on a break between periods of ice expansion called glaciations. A similar interglacial period occurred around 790,000 years ago. A new climate...

    No-pain gene discovered

    Mutations in a previously unscrutinized gene can leave people dangerously indifferent to harm, researchers report May 25 in Nature Genetics.

    Certain changes to this gene, PRDM12, rob people of the ability to feel pain, leading to unintentional injuries such as scarred tongues, scratched corneas and missing digits. A deeper...

    Nash’s mind left a beautiful legacy

    His mind was beautiful, but troubled. His math was just beautiful.

    John Forbes Nash Jr., who died in a traffic accident on May 23, gained more fame than most mathematicians, though not only on account of his math. His battle with schizophrenia, described artfully by...
