    Ticks are here to stay. But scientists are finding ways to outsmart them

    Thanks, Holly Gaff. Soon, anyone straining to tweeze off a mid-back tick can find answers to the obvious question: What if humankind just went after the little bloodsuckers with killer robots?

    Gaff, who calls herself a mathematical eco­epidemiologist, at Old Dominion University in Norfolk, Va., is one of the few people collecting real field data on the efficacy of tick-slaying robots....

    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...

    Gun research faces roadblocks and a dearth of data

    Buying a handgun in Connecticut means waiting — lots of waiting. First comes an eight-hour safety course. Then picking up an application at a local police department. Review of the application (which includes a background check and fingerprinting) can take up to eight weeks. If approved, the state issues a temporary permit, which the buyer trades in at state police headquarters for a permanent...

    Year in review: Pluto unveiled as a world like no other

    View the video

    Mountains of water ice tower thousands of meters over fields of frozen nitrogen and methane. Glaciers etched with channels hint at heat bubbling up from below. A patchwork of new and old terrains — some laid down in the last 10 million years, some as old as the planet itself — blanket the ground. And what appear to be two ice volcanoes punch through the terrain.

    The...

    Getting creative to cut methane from cows

    View the video

    In a pasture outside Edmonton, Canada, you’ll find a few dozen cows doing what cows do: mostly eating. The average animal spends eight-plus hours a day filling its belly, or as is the case with cows, bellies. Along with that enormous appetite, cows are born with the ability to digest almost any plant they can chew, thanks to a multichambered stomach and a helpful army of...

    Pluto’s smaller moons pose mysteries

    Pluto and Charon might have been the stars of the New Horizons mission, but the dwarf planet’s four smaller moons have some surprises to share as well.

    With images of Kerberos transmitted from the spacecraft on October 20, the Pluto family portrait is complete. The tiny moons Nix, Hydra, Kerberos and Styx are no longer pinpricks of light but textured, misshapen balls of ice that look...

    Lucy's new neighbor, downloading New Horizon's data and more reader feedback

    New Horizons phones home

    In “Pluto: Explored” (SN: 6/27/15, p. 16), Christopher Crockett chronicled New Horizons’ long journey to the dwarf planet. He followed up with a report on the successful flyby in “Pluto’s icy landscape comes into view” (SN: 8/8/15, p. 6).

    “Having read that early images of Pluto encoded in radio waves would take 4.5 hours to reach Earth from the New Horizons space...

    Rendezvous with Pluto

    View timeline

    Tiny, far-flung Pluto is about to have a visitor — at least for a few hours.

    On July 14, NASA’s New Horizons spacecraft will reach the dwarf planet and try to learn all it can about Pluto and its five known moons. Then the probe will leave Pluto behind, vanishing into the frigid darkness beyond the planets.

    In its wake, New Horizons will introduce Earth to the...

    An app to track firefly flashings

    A firefly flashing at dusk is an iconic sign of summer. Now you can enjoy these light shows and contribute to science at the same time with a firefly tracking app.

    There are around 2,000 species of these luminescent beetles, which light up the twilight with yellow, greenish or amber light. Scientists at Clemson University in South Carolina are concerned that firefly populations might be...
