    New experiment verifies quantum spookiness

    It’s official: Quantum mechanics is spooky.

    A new experiment provides the best evidence yet that the common-sense concept of locality — that an event on Earth can’t immediately influence what happens on Mars, for instance — doesn’t apply in the quantum realm.

    Researchers have long thought that quantum theory is nonlocal. But airtight...

    Hawking proposes solution to black hole problem

    Light sliding along the outside of a black hole is the key to understanding what’s inside, Stephen Hawking says.

    The proposal from the world’s most famous living physicist, presented August 25 at a conference in Stockholm, is the latest attempt to explain what happens to information that falls into the abyss of a black hole. Losing that information would violate a key principle of...

    Physicists get answers from computer that didn’t run

    For all that computers can do, they’re useless when they’re not running. That’s not the case for quantum computers. Using a rudimentary quantum computer, a team of physicists consistently determined which of two operations the computer would have performed, even though it didn’t actually perform them.

    The experiment, reported in the Aug. 21 Physical Review Letters, delivered an...

    Automated chemistry could build better drugs fast and cheap

    Mother Nature is a lazy chemist. Occasionally, she produces an organic molecule that’s a winning drug. But more often, a nature-made chemical’s medicinal powers are coupled with flaws, such as brutal side effects. Until recently, upping the safety of those drugs by retooling their parts was a lot like assembling Ikea furniture.

    Take amphotericin B, a lifesaving...

    Quantum communication takes a new twist

    Communications of the future may be securely encoded in light that is twisted like fusilli pasta.

    A long-distance transmission of particles of light above the Vienna skyline demonstrates a new way of relaying information using the tricks of quantum physics. Austrian researchers exploited the twistiness of light to establish a delicate quantum connection called entanglement between pairs...

    Biology may provide just the right chemistry for new drugs

    NORTH BETHESDA, Md. — Chemists are struggling to develop new drugs these days — and biologists may have just the pill for that.

    By tapping natural enzymes and tweaking microbes, researchers may find and make new drugs more easily, says biological engineer Vikramaditya Yadav of the University of British Columbia in Vancouver. Yadav says he has developed a method to make a complicated...

    Swimming bacteria remove resistance to flow

    Water flows best when it’s chock-full of synchronized-swimming bacteria.

    By coaxing billions of E. coli to work together, French researchers got a small sample of a bacteria-laden solution to have no resistance to flow, or zero viscosity. Such effortless motion is usually reserved for superfluids like liquid helium that are kept at frigid temperatures.

    “The results are...

    The arrow of time

    In T.H. White’s fantasy novel The Once and Future King, Merlyn the magician suffers from a rare and incurable condition: He experiences time in reverse. He knows what will happen, he laments, but not what has happened. “I have to live backwards from in front, while surrounded by a lot of people living forwards from behind,” he explains to a justifiably confused companion.

    While...

    Science is heroic, with a tragic (statistical) flaw

    First of two parts

    Science is heroic. It fuels the economy, it feeds the world, it fights disease. Sure, it enables some unsavory stuff as well — knowledge confers power for bad as well as good — but on the whole, science deserves credit for providing the foundation underlying modern civilization’s comforts and conveniences.

    But for all its heroic accomplishments, science...

    E-cigarette reports provide science that society craves

    For much of the last year, the most-read story on sciencenews.org was not about a faraway exoplanet or a cunning creature’s adaptations to an exotic locale. It was a short report, in some ways unsurprising. In 26 different weeks since it appeared in June 2014,...
