    Dazzling laser feats earn these physicists a Nobel

    Fantastic feats performed with lasers have earned three scientists the 2018 Nobel Prize in physics.

    Half of the award, which totals 9 million Swedish kronor (about $1 million), went to physicist Arthur Ashkin for his development of optical tweezers. The technique uses laser light to manipulate tiny particles such as viruses and bacteria.

    The other half of the prize went to two...

    Groundbreaking ways of manipulating light win trio the 2018 physics Nobel

    Three scientists who invented innovative ways to manipulate light have won the Nobel Prize in physics. The 9-million-Swedish-kronor award (about $1 million) will be doled out to Arthur Ashkin of Bell Laboratories in Holmdel, N.J., Gérard Mourou of École Polytechnique in Palaiseau, France, and Donna Strickland of the University of Waterloo in Canada, the Nobel Prize committee announced October...

    Manta rays have an unusual mouth filter that resists clogging

    Manta rays were built for speed — and to filter feed.

    The aerodynamic ocean dwellers efficiently separate plankton from seawater using a previously unknown kind of filtration system that resists clogs and captures tiny bits of plankton, researchers report September 26 in Science Advances.

    Mantas are filter feeders, like many other ocean creatures. They pull plankton-laden seawater...

    Ibrahim Cissé unlocks cells’ secrets using physics

    Ibrahim Cissé, 35Physics and biophysicsMIT

    Ibrahim Cissé expected to join his father’s law firm one day. “There were no scientists where I grew up in Niger,” says the MIT biophysicist. “I certainly didn’t know [science] was a profession one could do.”  

    But Cissé’s parents had a telling clue about their young son’s eventual career path: a door sign he made that read “Laboratoire de...

    Lisa Manning describes the physics of how cells move

    Lisa Manning, 38Physics and biologySyracuse University

    Think of tissues as mosh pits of cells. The cells may not be able to crowd surf, but they can jam.

    Specifically, cells can undergo a jamming transition, a physical role change that was previously known to occur only among foams, sand and other nonliving materials. It’s one of the ways that physicist Lisa Manning has shown how...

    Nuclear pasta in neutron stars may be the strongest material in the universe

    A strand of spaghetti snaps easily, but an exotic substance known as nuclear pasta is an entirely different story.

    Predicted to exist in ultradense dead stars called neutron stars, nuclear pasta may be the strongest material in the universe. Breaking the stuff requires 10 billion times the force needed to crack steel, for example, researchers report in a study accepted in Physical Review...

    Sound waves can make bubbles in levitated drops of liquid

    Save your breath: A new way to make bubbles requires only sound waves.

    Scientists made the bubbles in levitated drops of liquid, held aloft with sound waves. Tweaking the sound waves caused the hovering drop to balloon into a bubble.

    The team formed the bubbles using a variety of liquids, including water. Increasing the intensity of the sound made the liquid first buckle into a...

    A new hydrogen-rich compound may be a record-breaking superconductor

    Superconductors are heating up, and a world record-holder may have just been dethroned.

    Two studies report evidence of superconductivity — the transmission of electricity without resistance — at temperatures higher than seen before. The effect appears in compounds of lanthanum and hydrogen squeezed to extremely high pressures.

    All known superconductors must be chilled to function,...

    Readers’ interest piqued by Parker Solar Probe, general relativity and more

    Sunny-side up

    NASA’s Parker Solar Probe is on its way to “touch” the sun. Maria Temming reported on the mission before the August 12 launch in “NASA’s Parker probe is about to get up close and personal with the sun” (SN: 7/21/18, p. 12).

    Astronomy writer Lisa Grossman, who wrote a follow-up story, answered readers’ questions about the probe on Reddit.

    The strength of gravity has been measured to new precision

    We now have the most precise estimates for the strength of gravity yet.

    Two experiments measuring the tiny gravitational attraction between objects in a lab have measured Newton’s gravitational constant, or Big G, with an uncertainty of only about 0.00116 percent. Until now, the smallest margin of uncertainty for any G measurement has been 0.00137 percent.

    The new set of G values,...
