    Deep In Canadian Lakes, Signs Of Tar Sands Pollution

    The contaminants researchers found at the bottom of Alberta lakes are from air pollutants coming from tar sands oil production and processing facilities. The pollution wasn't picked up by the industry-funded monitoring program that was supposed to track environmental risks from tar sands over recent decades.

    Negative Temperatures That Are Hotter Than The Sun

    Scientists have cooled potassium gas to one billionth of a degree below absolute zero. But in the quantum world, that's actually hotter than the Sun. It's hotter, even, than infinity degrees Kelvin. Vladan Vuletić, a quantum physicist at MIT, talks about this 'Bizarro World' temperature.

    Cold-Water Fish Break The Ice With Antifreeze

    Cold-water fish, snow-dwelling bugs and some grasses have evolved natural antifreeze proteins to avoid turning to ice cubes. Peter Davies, a biologist at Queen's University in Ontario, discusses how these antifreeze substances work, and their applications for human problems--like keeping the ice out of ice cream.

    'Stand Your Ground' Linked To Increase In Homicides

    A controversial self-defense statute appears to produce more killings, according to a new study. Advocates for the law say it's working as designed. But researchers have different explanations about what might be happening.

    Can Skinny Models Undermine Your Dieting Goals?

    Many people turn to superfit models for weight-loss inspiration. There's growing evidence that this is a mistake. New research from the Netherlands explores whether repeated exposure to images of skinny models helps or hinders dieters.

    The Year Of The Higgs, And Other Tiny Advances In Science

    The discovery of the Higgs boson will likely be hailed as the most important scientific discovery of 2012. But many ideas that change the world don't tend to spring from flashy moments of discovery. Our view of nature — and our technology — often evolve from a sequence of more subtle advances.

    Research Moratoriums And Recipes For Superbugs: Bird Flu In 2012

    When scientists figured out how to make the deadly H5N1 virus more contagious, a debate ignited about whether to publish the research and do more experiments. Over the past year, scientists published the contentious work, but they still can't agree on the field's future.

    Despite Uneven Results, Alzheimer's Research Suggests A Path For Treatment

    The year saw some disappointments in the development of drugs to treat Alzheimer's. But the setbacks were offset by progress in other areas. The upshot from this year's mixed results, some scientists say, is that treatment for Alzheimer's needs to start long before forgetfulness and muddled thinking are apparent.

    Stem Cells Treat Lou Gehrig's Disease, In Mice

    Reporting in Science Translational Medicine, researchers write that neural stem cell implants were able to slow the onset of amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, in mice. Study author Evan Snyder discusses the stem cells' protective effect, and why human trials may not be far behind.
