    Centennial books illuminate Einstein’s greatest triumph

    You don’t need an anniversary as an excuse to write a book about Albert Einstein. But the centennial of his general theory of relativity has nonetheless provided an occasion for several new entries in the Einstein library. And even though general relativity — Einstein’s theory of gravity — has been thoroughly explored many times, some 2015 publications do offer new twists and insights.

    Einstein's genius changed science's perception of gravity

    Albert Einstein opened humankind’s eyes to the universe.

    Before Einstein, space seemed featureless and changeless, as Isaac Newton had defined it two centuries earlier. And time, Newton declared, flowed at its own pace, oblivious to the clocks that measured it. But Einstein looked at space and time and saw a single dynamic stage — spacetime — on which matter and energy strutted,...

    Fizzy bubbles carry drugs deep into wounds

    View the video

    Alka-Seltzer’s frothy fizz may hold the secret to stopping blood loss. 

    Jets of rushing bubbles can carry blood-clotting drugs deep into a wound and seal it shut, scientists report October 2 in Science Advances.

    The work is the first to show bubble-powered devices...

    What happens to animals in a hurricane?

    After hammering the Bahamas, Hurricane Joaquin is now moving north, and, the latest path predictions show, is headed out to sea instead of directly for the U.S. East Coast. The storm’s track has been hard to pin down, which makes preparing for it rather difficult. If you live near the shore, you don’t know if...

    First stars may lurk in our galactic neighborhood

    They’re hiding among us. Some of the first stars to appear in the universe might still be lurking in the Milky Way, masked by nearly 13 billion years of cosmic pollution.

    Computer simulations indicate that relatively lightweight first-generation stars might be scattered throughout the galaxy. Observations have yet to turn up any but that’s because exposure to interstellar dust and gas...

    Sperm protein may offer target for male contraceptive

    For 65 years, birth control pills have been exclusively for women. But men may be a step closer to getting in on the action, researchers report October 1 in Science.

    A newly identified sperm protein, called PPP3CC/PPP3R2, could give scientists a promising target for developing male contraceptives. The protein resides in...

    Kavli Foundation gives more money for the brain

    WASHINGTON — The Kavli Foundation is establishing three new institutes to accelerate research aimed at unlocking the mysteries of the brain. That research will align with the national BRAIN Initiative announced by President Obama in 2013. 

    The foundation, along with university partners, is providing over $100 million for...

    Giant asteroid may have triggered deadly volcano eruptions

    The demise of the dinosaurs may have been the result of a coordinated one-two punch.

    Eruption activity in a volcanic region in present-day India appears to have increased around the time of the asteroid impact that preceded the Cretaceous extinction, scientists report in the Oct. 2 Science. The close timing between the two events leads the scientists to suggest that...

    Brain cells’ DNA differs

    Nerve cells in the brain don’t all work from the same genetic blueprint. Individual neurons within a person’s skull harbor over a thousand distinct DNA mutations, scientists report in the Oct. 2 Science.

    The study “shows something fascinating — every neuron probably has a unique genome,” says neuroscientist Mike McConnell...

    Ceres mountains and craters named for food

    Tubers, maize and even eggplants are finally getting the astronomical recognition they deserve. Or at least that’s true for the deities that look after the crops and celebrations of their harvest. Fifteen craters and mountains on the dwarf planet Ceres were officially named on September 21 after various spirits and celebrations...
