    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...

    Weather forecasting is getting a high-speed makeover

    In late January, a massive snowstorm drifted toward New York City. Meteorologists warned that a historic blizzard could soon cripple the Big Apple, potentially burying the city under 60 centimeters of snow overnight. Governor Andrew Cuomo took drastic action, declaring a state of emergency for several counties and shutting down the city that never sleeps. For the first time in its 110-year...

    Sam Ting tries to expose dark matter's mysteries

    In the near vacuum of outer space, each rare morsel of matter tells a story. A speedy proton may have been propelled by the shock wave of an exploding star. A stray electron may have teetered on the precipice of a black hole, only to be flung away in a powerful jet of searing gas.

    Since 2011, the International Space Station has housed an experiment that aims to decipher those origin...

    Climbing high to save a threatened West Coast plant

    Protruding from a cliff face, a diminutive desert plant peered across a sapphire channel as flames charred the earth hundreds of feet below. The remote pinnacle should have protected the onlooker, as it had in the past, but the blaze was too hot. This time, the mountain burned, and the tiny succulent, known as Verity’s liveforever, wilted and died.

    As the May 2013 Camarillo Springs fire...

    Seeing past the jellyfish sting

    Robots that hunt down and exterminate jellyfish: Good or bad idea? Discuss.

    A 2013 video from robotics designers at the Korea Advanced Institute of Science and Technology shows three jelly-killer prototypes gliding as a metallic fleet over gently rippling water. An underwater video demonstrates the cunning plan. Pale jellyfish bells drift into view, and a...

    Quantum timekeeping

    The best clock in the world has no hands, no pendulum, no face or digital display. It’s a jumble of lasers, wires and strontium atoms in Jun Ye’s lab at the National Institute of Standards and Technology (NIST) in Boulder, Colo. He keeps it cooled to about three millionths of a degree above absolute zero.

    The clock, described by Ye in the Feb. 6 Nature, is so precise that had it begun...

    Life under ice

    Even by Antarctic standards, the Lake Vostok research station is inhospitable. The outpost at the heart of the frozen continent holds the record for the lowest naturally occurring temperature ever observed on Earth. Scientists commonly describe the place as punishing, unforgiving, the most desolate place on the planet.

    That’s nothing. Nearly 4,000 meters below the...

    Aliens in Antarctica

    It was a summer day in January when Peter Convey pulled up a weed in Antarctica for the first time. The alien plant stuck out among the native species eking out an existence on the rocky debris beneath his feet.

    Convey doesn’t know for sure how the intruder, a rugged relative of the ornamental plant gerbera, traveled from its usual home 1,000...

    Fertile Frontiers

    The solar system’s spotted bully and its ringed sidekick are holding some tantalizing treasures in their gravitational clutches. Circling Jupiter and Saturn are more than a hundred moons, including some of the most promising hosts for extraterrestrial life in the solar system.

    But not every one of these moons is an equal opportunity extraterrestrial petri dish....

    Plastics ingredient causes genetic response A new study shows for the first time that bisphenol A — a building block of some plastics and food-packaging materials — can trigger hormone-responsive gene changes in people. An international research team collected blood and urine from 96 male recruits. As urinary markers of BPA exposure rose, the likelihood that estrogen-responsive genes were...
