All Stories by Peter Weiss

  1. Physics

    Quantum computers to keep an eye on

    A primitive ion-based computer exploiting the weirdness of quantum mechanics has taken an important step forward in problem solving.

  2. Tech

    Fiber Helper: Minuscule controllers may open data floodgates

    A device that fits on the end of optical fibers may make possible the next big boost in Internet speed without new underground cables.

  3. Physics

    Clocking gravity

    The first attempt to measure the speed of gravity finds it roughly equal to that of light, as expected, though not everyone agrees that the method used can actually measure gravity's speed.

  4. Tech

    A Shot in the Light

    Bullet replicas that look on a microscopic level like they've been fired from a gun—even though they haven't—enable forensics specialists to fine-tune as never before instruments to automatically match bullets from crime scenes.

  5. Physics

    Prying apart antimatter

    Matter and antimatter look reassuringly alike in physicists' first investigations of energy levels of antihydrogen atoms.

  6. Physics

    Prying apart antimatter

    Matter and antimatter look reassuringly alike in physicists' first investigations of energy levels of antihydrogen atoms.

  7. Physics

    Getting Warped

    While museum displays such as simulations of warped space-time acquaint visitors with the ideas behind Albert Einstein's scientific discoveries, other galleries of artifacts, letters, and even film footage reveal the multifaceted man that Einstein was.

  8. Physics

    Light chips find a place to take root

    The fabrication of an artificial, inside-out opal of silicon promises to make all-optical microchips possible

  9. Physics

    Atom microchips get off the ground

    Becoming smaller and more versatile, microchips using atoms instead of electrons promise both to improve atomic physics experiments and to pave the way for new technologies such as quantum computers.

  10. Physics

    Connect the Dots

    Transforming sunlight into electricity by means of quantum dust.

  11. Physics

    Identity Check: Elusive neutrinos morph on Earth, as in space

    Strengthening a challenge to the prevailing theory of particle physics, measurements of elusive particles called antineutrinos from nuclear reactors suggest that no neutrino types, be they matter or antimatter, have stable identities.

  12. Tech

    Satellite links may don quantum cloaks

    A theoretically foolproof scheme to shield secrets via the laws of quantum mechanics demonstrates its readiness to take on Earth-satellite communications.
