    ‘Invisible Women’ spotlights a gaping and dangerous gender data gap

    Invisible WomenCaroline Criado PerezAbrams Press, $27

    The recent cancellation of the first all-female spacewalk occurred after the publication of Caroline Criado Perez’s Invisible Women. But the news — the lack of enough space suits for the women, suits which weren’t designed for the shape of women’s bodies in the first place — would fit right in to Criado Perez’s scathing takedown...

    A scientist used chalk in a box to show that bats use sunsets to migrate

    When it comes to migration science, birds rule. Although many mammals — antelopes, whales, bats — migrate, too, scientists know far less about how those animals do it. But a new device, invented by animal navigation researcher Oliver Lindecke, could open a new way to test how far-ranging bats find their way.

    Lindecke, of Leibniz Institute for Zoo and Wildlife Research in Germany, has...

    The herbal supplement kratom comes with risks

    Kratom, an herbal supplement available at vape shops and online stores, has been linked to 91 deaths over 18 months from July 2016 to December 2017, according to a report by the U.S. Centers for Disease Control and Prevention.Those deaths made up less than 1 percent of the 27,338 overdose fatalities analyzed for the report, released online on April 12. Although small, the numbers point to...

    More than a million tiny earthquakes revealed in Southern California

    In between the “big ones,” millions of tiny, undetected earthquakes rumble through the ground. Now, a new study uncovers a decade’s worth of such “hidden” quakes in Southern California, increasing the number of quakes logged in the region tenfold. Such troves of quake data could shake up what’s known about how temblors are born belowground, and how they can interact and trigger one another,...

    A genetic scorecard could predict your risk of being obese

    There’s a new way to predict whether a baby will grow into an obese adult.

    Combining the effect of more than 2.1 million genetic variants, researchers have created a genetic predisposition score that they say predicts severe obesity. People with scores in the highest 10 percent weighed, on average, 13 kilograms (about 29 pounds) more than those with the lowest 10 percent of scores, the...

    Immigrants pave the way for the gentrification of black neighborhoods

    Many think of gentrification today as wealthy, white millennials moving into low-income, minority neighborhoods and driving up housing costs. Yet a new study suggests that another group may play a key role in the process: immigrants.

    Gentrification, in which affluent outsiders settle and renovate rundown neighborhoods, generally decreases in white neighborhoods when immigrants from Asia...

    Warm, dry winds may be straining Antarctica’s Larsen C ice shelf

    Turquoise pools of snowmelt on the Antarctic Peninsula, including on the Larsen C ice shelf, have recently been forming months after the continent’s peak summer melt. Bursts of warm, dry wind cascading over mountains that run along the peninsula are largely to blame, researchers report April 11 in Geophysical Research Letters. In this March 2016 satellite image, meltwater on part of Larsen C...

    Dead pig brains bathed in artificial fluid showed signs of cellular life

    Scientists have restored cellular activity to pig brains hours after the animals’ death — an unprecedented feat. This revival, achieved with a sophisticated system of artificial fluid, took place four hours after the pigs’ demise at a slaughterhouse.

    “This is a huge breakthrough,” says ethicist and legal scholar Nita Farahany of Duke University, who wasn’t involved in the research. “It...

    The first type of molecule to form in the universe has been seen in space

    Helium hydride ions, thought to be the first type of molecule to form in the universe, have finally been spotted in space.

    These charged molecules, each made of a neutral helium atom and a positively charged hydrogen atom, first emerged within about 100,000 years after the Big Bang. Back then, the universe was composed almost entirely of hydrogen and helium, and helium hydride was the...

    Parenting chores cut into how much these bird dads fool around

    The extreme dads of the bird world do all the work raising chicks while females fight intruders. The result: Male black coucals don’t sleep around as much when busy parenting.

    On occasion, a male black coucal (Centropus grillii) slips over to another male’s nest to sire a chick. The demands of incubating eggs, however, reduce a male’s excursions about 17 percent, on average, compared...
