    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...

    DNA architecture, novel forensics offer new clues

    It’s one thing to catalog each chemical unit of DNA that makes up the human genome. It’s another thing entirely to understand how that genetic material is folded up inside a living cell — and then decoded, manipulated and used.

    Achieving that...

    Wanted: Crime-solving bacteria and body odor

    Forensic biologist Silvana Tridico was puzzled by pubic hair.

    Specifically, pubic hair samples donated by two volunteers.

    She had just finished analyzing the bacteria stuck to the hair of seven people. If each hair sample carried unique mixes of bacteria, Tridico reasoned, investigators might have a new tool to help identify crime suspects. Hair bacteria, like fingerprints, could...

    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...

    Quest for room-temperature superconductivity warms up

    The tantalizing but contentious claim that a material can conduct electrical current without resistance at temperatures as high as –70° Celsius has cleared another hurdle: It’s been published in a peer-reviewed journal. A study published August 17 in Nature provides...

    Three kids’ science books offer fun, fascinating experiments

    Summer has flown by. As the school year begins, three recently published books can pique kids’ curiosity about science and get them experimenting. The books, newly out in paperback or revised edition, offer a wealth of ideas for budding naturalists, physicists or chemists.

    Many at-home, do-it-yourself physics books boast that their experiments can be done with household items, but then...

    Pathway pieced together to make opiates in yeast

    Out of a poppy and into a yeast. Scientists have engineered yeast to make sugar into thebaine, a precursor to opiates such as morphine. The work brings together the beginning and recently identified central...

    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...
