    Mars’ lake may need an underground volcano to exist

    If Mars conceals a lake beneath its south polar ice cap, the planet must also have a hidden chamber of magma to keep the water liquid, a new analysis suggests.

    Signs of a 20-kilometer-wide lake, buried beneath about a kilometer and a half of ice near Mars’ south pole, were first reported in 2018 by a team led by planetary scientist Roberto Orosei (SN: 8/18/18, p. 6). The discovery kicked...

    The quest for quasicrystals is a physics adventure tale

    The Second Kind of ImpossiblePaul J. SteinhardtSimon & Schuster, $27

    When Paul Steinhardt made a discovery that he had been working toward for more than 20 years, he did not cry “Eureka!” On that winter morning in the lab in 2009, he writes, he and a colleague “were dead silent, because no words were necessary.”

    Steinhardt had just found a natural quasicrystal, a solid...

    Tidal floods driven by climate change may hurt small businesses

    WASHINGTON — Sea level rise, driven by climate change, is causing increased flooding during high tides along much of the U.S. coastline. Though such floods are usually minor, a new study suggests that car traffic patterns could help reveal how floods harm an area’s business revenues.

    Tidal flooding events “are not one in a hundred years or one in a thousand years. They’re once a week,”...

    Brain cells combine place and taste to make food maps

    Sometimes a really good meal can make an evening unforgettable. A new study of rats, published online February 18 in the Journal of Neuroscience, may help explain why. A select group of nerve cells in rats’ brains holds information about both flavors and places, becoming active when the right taste hits the tongue when the rat is in a certain location. These double-duty cells could help...

    Tooth plaque shows drinking milk goes back 3,000 years in Mongolia

    WASHINGTON — Ancient people living in what’s now Mongolia drank milk from cows, yaks and sheep — even though, as adults, they couldn’t digest lactose. That finding comes from the humblest of sources: ancient dental plaque.

    Modern Mongolians are big on dairy, milking seven different animal species, including cows, yaks and camels. But how far into the past that dairying tradition extends...

    Why some Georgia O’Keeffe paintings have ‘art acne’

    WASHINGTON — Like pubescent children, the oil paintings of Georgia O’Keeffe have been breaking out with “acne” as they age, and now scientists know why.

    Tiny blisters, which can cause paint to crack and flake off like dry skin, were first spotted forming on the artist’s paintings years ago. O’Keeffe, a key figure in the development of American modern art, herself had noticed these knobs...

    LIGO will be getting a quantum upgrade

    WASHINGTON — Gravitational wave detectors are going quantum.

    A planned revamp of the Advanced Laser Interferometer Gravitational-Wave Observatory, LIGO, relies on finessing quantum techniques, LIGO scientists announced February 14. That $35 million upgrade could let scientists catch a gravitational wave every day, on average. LIGO’s current tally of 11 gravitational wave events could be...

    STEM professors’ beliefs on intelligence may widen the racial achievement gap

    WASHINGTON — Beliefs among some university professors that intelligence is fixed, rather than capable of growth, contribute to a racial achievement gap in STEM courses, a new study suggests.

    Those professors may subtly communicate stereotypes about blacks, Hispanics and Native Americans allegedly being less intelligent than Asians and whites, say psychologist Elizabeth Canning of Indiana...

    Muons reveal the whopping voltages inside a thunderstorm

    An invisible drizzle of subatomic particles has shown that thunderstorms may store up much higher electric voltages than we thought.

    Using muons, heavier relatives of electrons that constantly rain down on Earth’s surface, scientists probed the insides of a storm in southern India in December 2014. The cloud’s electric potential — the amount of work necessary to move an electron from one...
