    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...

    Elusive acid finally created

    After more than a century of searching, chemists have finally nabbed a legendary acid.

    The acid called cyanoform or tricyanomethane appears widely in textbooks as one of the strongest carbon-based acids known. Yet despite attempts to make the acid dating back to 1896, cyanoform has evaded chemists until now. Researchers report September 18 in Angewandte Chemie International Edition...

    Quantum choice can be counterproductive

    When abiding by the laws of quantum physics, having options can make an otherwise simple task impossible. A new paper demonstrates that transmitting quantum messages becomes more difficult if the intended recipient offers the sender multiple options for the time and place of delivery.

    The strange finding, described online September 16 at, joins other paradoxes such as...

    Raw chicken, ingenuity make a time-reversal mirror

    Light that strikes a new and improved mirror is always returned to sender.

    South Korean physicists have created a composite mirror, made up of about a thousand tiny reflectors, that coaxes light waves to retrace, in reverse, the paths taken by the original waves that struck it. As a result, the...

    Invisibility cloaks slim down

    A new invisibility cloak offers more stealth in a thinner package.

    The 80-nanometer-thick “skin cloak,” reported in the Sept. 18 Science, drapes over a micrometer-sized object and renders it undetectable for a specific wavelength of red light. Light waves bounce off the shielded entity as if they were...

    Electron waves refract negatively

    Nearly a decade after getting waves of light to bend backward, physicists have done the same with electrons.

    Electrons coursing through a sheet of carbon atoms exhibited negative refraction, bending at angles not seen in nature, physicists report September 14 in Nature Physics. By exploiting this unusual bending, the...
