    All about Me: Left brain may shine spotlight on self

    Plenty of evidence indicates that the recognition of familiar faces depends largely on structures on the right side of the brain's outer layer, or cortex. However, the brain appears to take a sharp left turn in fostering the ability to identify one's own face.

    That, at least, is the implication of experiments conducted with a so-called split-brain patient. To curb the spread of severe...

    What's the Mane Point? Foes and females both have role

    Zoologists since the 1800s have pondered the purpose of the lion's mane, conjecturing that the mop either serves to defend against competitors' claws and teeth or to attract a female. Now the first experimental study to consider the question suggests a mane's condition advertises high-quality mates to picky females and wards off male adversaries.

    A Cut above the Ordinary: Low-tech machining yields coveted nanostructure

    Drills, lathes, and milling machines produce metal trimmings that machine shops discard as trash or melt down for reuse. A new study finds that these trimmings often end up with a fine-grained and especially hard microscopic structure equivalent to that of expensive high-tech materials.

    Because the presence of this hard structure endows materials with exceptional strength...

    Peer Pressure in Numbers: Physicists model the power of social sway

    Aromas from a kitchen fill a house. A drop of dye colors an entire bucket of water. It's all because molecules diffuse; they roam around in all directions.

    But what would happen if the molecules–instead of moving completely randomly–were influenced by peer pressure? If molecules or particles or people tended to follow the paths of their trendiest neighbors, they might aggregate, even in...

    Lost in Space: Comet mission appears to have broken apart

    Just 2 weeks ago, the CONTOUR probe, launched July 3, was beginning its journey to two comets, one of which had broken into pieces. It now appears that the $159 million spacecraft has itself broken apart.

    "I feel like I lost a relative," says planetary scientist Lucy-Ann A. McFadden of the University of Maryland in College Park.

    Engineers haven't heard from CONTOUR, or...
