    Venomous fish have evolved many ways to inflict pain

    Biologist Leo Smith held an unusual job while an undergraduate student in San Diego. Twice a year, he tagged along on a chartered boat with elderly passengers. The group needed him to identify two particular species of rockfish, the chilipepper rockfish and the California shortspine thornyhead. Once he’d found the red-orange creatures, the passengers would stab themselves in the arms with the...

    How the house mouse tamed itself

    Got a mouse in the house? Blame yourself. Not your housekeeping, but your species. Humans never intended to live a mouse-friendly life. But as we moved into a settled life, some animals — including a few unassuming mice — settled in, too. In the process, their species prospered — and took over the world.

    The rise and fall of the house mouse’s fortunes followed the stability and...

    Cancer cells cast a sweet spell on the immune system

    Shrink yourself small enough to swoop over the surface of a human cell, and you might be reminded of Earth’s terrain. Fats, or lipids, stay close to the surface, like grasses and shrubs. Proteins stand above the shrubs, as mighty oaks or palm trees. But before you could distinguish the low-lying lipids from the towering proteins, you’d see something else adorning these molecules — sugars.

    Nudging people to make good choices can backfire

    Nudges are a growth industry. Inspired by a popular line of psychological research and introduced in a best-selling book a decade ago, these inexpensive behavior changers are currently on a roll.

    Policy makers throughout the world, guided by behavioral scientists, are devising ways to steer people toward decisions deemed to be in their best interests. These simple interventions don’t...

    ‘Monkeytalk’ invites readers into the complex social world of monkeys

    MonkeytalkJulia FischerUniv. of Chicago, $25

    The social lives of macaques and baboons play out in what primatologist Julia Fischer calls “a magnificent opera.” When young Barbary macaques reach about 6 months, they fight nightly with their mothers. Young ones want the “maternal embrace” as they snooze; mothers want precious alone time. Getting pushed away and bitten by dear old...

    Physics greats of the 20th century mixed science and public service

    The 20th century will go down in history — it pretty much already has — as the century of the physicist. Physicists’ revolutionizing of the scientific world view with relativity and quantum mechanics might have been enough to warrant that conclusion. Future historians may emphasize even more, though, the role of physicists in war and government. Two such physicists, one born at the century’s...

    Analysis finds gender bias in peer-reviewer picks

    Gender bias works in subtle ways, even in the scientific process. The latest illustration of that: Scientists recommend women less often than men as reviewers for scientific papers, a new analysis shows. That seemingly minor oversight is yet another missed opportunity for women that might end up having an impact on hiring, promotions and more.  

    Peer review is one of the bricks in the...

    Hidden Figures highlights three black women who were vital to the U.S. space program

    View trailer

    Hollywood space flicks typically feature one type of hero: astronauts who defy the odds to soar into space and back again. But now a group of behind-the-scenes heroes from the early days of the U.S. space program are getting their due. Black female mathematicians performed essential calculations to safely send astronauts to and from Earth’s surface — in defiance of flagrant...

    Year in review: Gravitational waves offer new cosmic views

    The secrets gleaned from the universe’s most mysterious giants are incongruously subtle when witnessed at Earth: Detectors budge by a tiny fraction of a proton’s breadth, outputting a feeble, birdlike chirp.

    For centuries, astronomers have peered out into the universe almost exclusively by observing its light. But 2016’s announcement of the first detection of gravitational waves,...

    Year in review: Ozone hole officially on the mend

    In a rare bright spot for global environmental news, atmospheric scientists reported in 2016 that the ozone hole that forms annually over Antarctica is beginning to heal. Their data nail the case that the Montreal Protocol, the international treaty drawn up in 1987 to limit the use of ozone-destroying chemicals, is working.

    The Antarctic ozone hole forms every Southern Hemisphere spring...
