    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 icy landscape comes into view

    LAUREL, Md. — Alan Stern, head of the New Horizons mission to Pluto, had just three words for the team of scientists and engineers assembled with him on July 14: “We did it.”

    At 8:52:37 p.m. Eastern time, a radio antenna near Madrid received the first signal from the spacecraft since it buzzed the dwarf planet. After decades of planning and a 9.5-year journey...

    Deep network

    Gas bubbles effervesce from a mound of muck on the seafloor in a deep submarine canyon off the west coast of Canada. Microbes beneath the sediment belch the bubbles after feasting on the ancient remains of algae, sea critters and their poop: a primordial stew that’s been simmering since long before humans walked the Earth.

    This gassy oasis attracts an odd collection of critters. Worms...

    The 3-D Printing Revolution

    Joshua Pearce takes unusual satisfaction in strolling through Walmart. The shelves laden with toys, household items, tools and clothing inspire in him a certain smugness, a pride in American entrepreneurship. But it’s not because Pearce admires the chain as an empire built by a self-made man. Pearce swells with pride at Walmart because the store is full of mass-manufactured objects that he...

    De-papering environmental summits

    This week, the United Nations hosted a major conclave in Rio de Janeiro — the 2012 Conference on Sustainable Development. Widely referred to as Rio+20, its timing commemorated the 20th anniversary of the so-called Earth Summit in this Brazilian capital. As one token — but highly visible — gesture toward sustainability, the new event encouraged all attendees to shrink their paper footprints....

    Isotope crisis threatens medical care

    Within the next two weeks, the vast majority of radioactive-imaging medical tests could be delayed or replaced by less desirable procedures. The reason: temporary shutdowns of Canadian and Dutch reactors that together normally provide some 70 percent of the world’s supplies of the isotope molybdenum-99 and at least 80 percent of North American supplies.

    Each week, U.S. doctors...

    Scientists Get a 2nd Life

    To track down neuroscientist Corey Hart, you could stop by his laboratory, located on the second floor of DrexelUniversity’s medical building in Philadelphia. Or, you could visit the lab of Luciftias Neurocam, located in the virtual world of Second Life.

    Luciftias is Hart’s digital alter ego, or avatar. Like his real-life counterpart, Luciftias tracks the...

    That's One Weird Tooth

    What Martin Nweeia noticed first when he encountered narwhals, he says, was the sound. In May 2000, as spring was just reaching Baffin Island in the Canadian Arctic, a famed local hunter took Nweeia out on the ice searching the open water for those tusk-bearing, high-Arctic whales. "I was sitting on a bucket out on the ice doing polar bear watch," he says. At that time of year, daylight lasts...

    Images from the Edge

    David Schiminovich stared at a gallery of spiral galaxies as though he had never seen anything like them before. Indeed, no one had. He sat downloading the newly collected images in a narrow room overlooking a cavernous space at the California Institute of Technology in Pasadena. In that space, the mirror for the Palomar Telescope—until the mid 1970s, the world's largest telescope—had been...
