    Quantum satellite shatters entanglement record

    Particles of light born in space have connected two cities via a quantum link about 10 times longer than any created before.

    A quantum-communications satellite beamed photons to Earth, separating them by more than 1,200 kilometers. The feat showed that the particles of light can retain a strange type of interconnectedness, known as quantum entanglement, even when flung to opposite ends...

    Top 10 discoveries about waves

    Physics fans are a lot like surfers. Both think waves are really fun.

    For surfers, it’s all about having a good time. For physicists, it’s about understanding some of nature’s most important physical phenomena. Yet another detection of gravitational waves, announced June 1, further reinvigorates the world’s science fans’ excitement over waves.

    Waves have naturally always been a...

    New video camera captures 5 trillion frames every second

    View the video

    A new video camera, the fastest by far, has set a staggering speed record. It films 5 trillion frames (equivalent to 5 trillion still images) every second, blowing away the 100,000 frames per second of high-speed commercial cameras. The device could offer a peek at never-before-seen phenomena, such as the blazingly fast chemical reactions that drive explosions or...

    Einstein’s light-bending by single far-off star detected

    For the first time, astronomers have seen a star outside of the solar system bend the light from another star. The measurement, reported June 7 in Austin, Texas, at a meeting of the American Astronomical Society, vindicates both Einstein’s most famous theory and what goes on in the inner lives of stellar corpses.

    Astronomers using the Hubble Space Telescope watched as a white dwarf...

    Quantum tractor beam could tug atoms, molecules

    The wavelike properties of quantum matter could lead to a scaled-down version of Star Trek technology. A new kind of tractor beam could use a beam of particles to reel in atoms or molecules, physicists propose in the May 5 Physical Review Letters.

    Scientists have previously created tractor beams using light or sound waves, which can pull small particles a few millimeters or centimeters (...

    Naked singularity might evade cosmic censor

    Certain stealthy spacetime curiosities might be less hidden than thought, potentially exposing themselves to observers in some curved universes.

    These oddities, known as singularities, are points in space where the standard laws of physics break down. Found at the centers of black holes, singularities are generally expected to be hidden from view, shielding the universe from their...

    New printer creates color by shaping nanostructures

    Carving nanostructures with a laser creates long-lasting colors.

    Researchers developed the new printing technique as an alternative to ink-based printing, in which colors fade with time. Aside from eternally vibrant art, the technique could lead to new types of color displays or improve security labels, the scientists report in the May 5 Science Advances.

    Anders Kristensen of...

    Key Einstein principle survives quantum test

    Particles with mind-bending quantum properties still follow a standard gravitational rule, at least as far as scientists can tell.

    The equivalence principle — one of the central tenets of Einstein’s theory of gravity — survived a quantum test, scientists report online April 7 at arXiv.org.

    In Einstein’s gravity theory — the general theory of relativity — gravity and acceleration...

    Top 10 science anniversaries of 2017

    Second of two parts

    Every year science offers a diverse menu of anniversaries to celebrate. Births (or deaths) of famous scientists, landmark discoveries or scientific papers — significant events of all sorts qualify for celebratory consideration, as long as the number of years gone by is some worthy number, like 25, 50, 75 or 100. Or simple multiples thereof with polysyllabic names....
