    Enough With Baby Talk; Infants Learn From Lemur Screeches, Too

    Even infants too young to discern the meaning of words seem better able to learn while listening to the sound of human speech than while listening to nonsense — speech run backward. Little surprise there, perhaps, but a study shows that recordings of lemur calls spark learning, too.

    A Cooler Pacific May Be Behind Recent Pause In Global Warming

    The Earth's average annual temperature has been rising for decades, but not in the last 15 years — colder winters and hotter summers notwithstanding. Now scientists offer evidence that this "pause" in average warming is because a cooler Pacific is temporarily taking up more heat than usual.

    Julia Child Was Wrong: Don't Wash Your Raw Chicken, Folks

    The doyenne of TV chefs imparted much wisdom to American cooks, but one piece of Child's advice you should ignore is to wash your raw poultry before cooking. It spreads germs. Everywhere. Yet studies suggest 90 percent of Americans do it, so food safety researchers are launching a campaign to squash the habit.

    Sophisticated Prosthetics Help Liberate Disabled Adventurers

    New technology is revolutionizing disabled peoples' ability to have the kind of outdoor adventures many had before losing functionality in their limbs. Amputees and people with spinal cord injuries are now off-road hand cycling, rock climbing and whitewater kayaking. Companies making innovative new gear describe cool recent innovations and challenges they're still working on. Disabled adventurers experienced and new to the scene talk about liberation through technology.

    Turning Off The Spigot In Western Kansas Farmland

    If Kansas farmers keep pumping water out of the High Plains aquifer as they have in the past, the amount of water they can extract will start to fall in just 10 years or so, scientists predict. That will cause big changes in the agricultural economy. But reducing water use now could help delay and ease that disruption.

    The 'Consensus' View: Kevin Trenberth's Take On Climate Change

    Climate skeptics point to 15 years of no warming trend as a reason to doubt global warming. But Kevin Trenberth at the National Center for Atmospheric Research can explain a good bit of that temperature plateau — and he argues the Earth has continued to warm appreciably, even though our thin blanket of atmosphere hasn't.
