    Ultrathin 2-D metals get their own periodic table

    A new version of the periodic table showcases the predicted properties of 2-D metals, an obscure class of synthetic materials.

    Arrayed in 1-atom-thick sheets, most of these 2-D metals have yet to be seen in the real world. So Janne Nevalaita and Pekka Koskinen, physicists at the University of Jyväskylä in Finland, simulated 2-D materials of 45 metallic elements, ranging from lithium to...

    Trio of dead stars upholds a key part of Einstein’s theory of gravity

    OXON HILL, Md. — Observations of a trio of dead stars have confirmed that a foundation of Einstein’s gravitational theory holds even for ultradense objects with strong gravitational fields.

    The complex orbital dance of the three former stars conforms to a rule known as the strong equivalence principle, researchers reported January 10 at a meeting of the American Astronomical Society....

    Watch our most-viewed videos of 2017

    No story on the Science News website is complete without visuals. And when it comes to videos, those visuals have lives of their own on other platforms. In addition to incorporating videos into some of our articles, we also post videos to the Science News YouTube channel and the Science News magazine Facebook page, where thousands of people watch them each year.

    We tackled all manner of...

    These 2017 discoveries could be big news, if they turn out to be true

    Some reports from 2017 hint at potentially big discoveries — if the research holds up to additional scientific scrutiny.

    Under pressure

    Putting the squeeze on hydrogen gas turned it into a long-elusive metal that may superconduct, Harvard University physicists claimed (SN: 2/18/17, p. 14). A diamond vise, supercold temperatures and intense pressure made the element reflective — a key...

    Smothered jet may explain weird light from neutron star crash

    View the video

    The neutron star collision heard and seen around the world has failed to fade. That lingering glow could mean that a jet of bright matter created in the crash has diffused into a glowing, billowy cocoon that surrounds the merged star, researchers report online December 20 in Nature.

    Gravitational waves from the collision between two ultradense stellar corpses was...

    A new kind of spiral wave embraces disorder

    View the video

    A type of spiraling wave has been busted for disorderly conduct.

    Spiral waves are waves that ripple outward in a swirl. Now scientists from Germany and the United States have created a new type of spiral wave in the lab. The unusual whorl has a jumbled, disordered center rather than an orderly swirl, making it the first “spiral wave chimera,” the researchers report...

    This year’s neutron star collision unlocks cosmic mysteries

    Thousands of astronomers and physicists. Hundreds of hours of telescope observations. Dozens of scientific papers. Two dead stars uniting into one.

    In 2017, scientists went all in on a never-before-seen astronomical event of astounding proportions: a head-on collision between two neutron stars, the ultradense remnants of exploded stars.

    The smashup sent shivers of...

    Some high-temperature superconductors might not be so odd after all

    A misfit gang of superconducting materials may be losing their outsider status.

    Certain copper-based compounds superconduct, or transmit electricity without resistance, at unusually high temperatures. It was thought that the standard theory of superconductivity, known as Bardeen-Cooper-Schrieffer theory, couldn’t explain these oddballs. But new evidence suggests that the standard theory...

    Microwaved, hard-boiled eggs can explode. But the bang isn’t the worst part.

    Hard-boiled eggs are a dish best served cold.

    When quickly reheated in a microwave and then pierced, the picnic staple can explode with a loud bang in a shower of hot, rubbery shrapnel. But this blast is far more likely to make a hot mess than hurt your hearing, according to research presented December 6 at the Acoustical Society of America meeting in New Orleans.

    That distinction...

    How freezing a soap bubble turns it into a ‘snow globe’

    View the video

    Frigid air can transform an ordinary soap bubble into a glittery “snow globe.” No shaking required.

    When a bubble is placed in a freezer set to –20° Celsius, delicate ice crystals swirl gracefully across the soapy film, gradually growing larger until the bubble freezes solid. The phenomenon can also be observed when blowing soap bubbles outside in wintry weather....
