    Slashing Fossil Fuel Consumption Comes With A Price

    The U.S. aims to reduce carbon dioxide emissions by 80 percent by 2050. Wind and solar power can help. But folks doing the math say other pricey, controversial technologies — such as burying carbon gas underground, and expanding nuclear power — are also likely to be part of a low-carbon future.

    From Lab To Lectern, Scientists Learn To Turn On the Charm

    Science isn't known as a career field that attracts showboats. But academics must give seminars, pharmaceutical researchers present results, and graduate students defend their work. In San Diego, one of the country's science hubs, a group aims to teach scientists the art of small talk and public speaking.

    Phantom Traffic Jams: What Causes Mysterious Highway Backups?

    Sometimes highway traffic jams up for no apparent reason. There's no accident, and no real reason to step on the brakes — except to avoid hitting the car in front of you. What causes these backups? An MIT scientist thinks he's found a way to prevent these tie-ups.

    By Accident, Scientists Discover Lakes Beneath Greenland

    There are hundreds of lakes beneath the Antarctic ice sheet, but nobody has found lakes under Greenland's ice. That is until now, and they weren't even looking for them.

    U.S. May Be Producing 50 Percent More Methane Than EPA Thinks

    Previous estimates of the climate-warming gas were based on the rough number of methane-emitting sources on the ground — such as factories, refineries, stoves, swamps, landfills and cattle herds. But by directly measuring levels of methane in the air instead, a new study puts the total much higher.

    At Climate Meeting, Tensions Rise Between Rich And Poor Nations

    At the United Nations climate talks in Warsaw, Poland, conflict between rich and poor nations is mounting. The developing world wants large sums of money to help them adapt to climate change. The U.S. and Europe say they're doing what they can to help but times are tough.

    Antibiotic Use On The Farm: Are We Flying Blind?

    No one knows exactly how farmers use antibiotics. Many public health experts say the government should collect and publish detailed information because antibiotic-resistant bacteria are an increasingly urgent problem. But many farm groups are opposed.
  • These pigs, newly weaned from their mothers, are at their most vulnerable stage of life. They're getting antibiotics in their water to ward off bacterial infection.

    Are Antibiotics On The Farm Risky Business?

    Farmers give antibiotics routinely to pigs, beef cattle and poultry. They say the drugs help keep animals healthy and get them to market faster. Others say this practice practically guarantees that bacteria will develop resistance to these antibiotics more quickly, endangering human lives and the long-term viability of the drugs.
