A Stomping Good Time at Family Science Days
R2-D2, a large lizard, and scores of scientists and science educators welcomed kids to Family Science Days at the 2013 AAAS Annual Meeting. Stomping on plastic bottles to launch rockets and painting with glowing bacteria were some of the popular activities.
The Skin We're In
There are two aspects of skin color: biological and social. Nina Jablonski, talks about the evolution of our ancestors' skin color and the cultural meanings that resulted.
Painful Consequences of Upright Walking
As critical as they are for moving around, human feet are far from perfect. The 26-bone structure is mechanically inefficient and feet are prone to flat-footedness, ankle sprains, and other painful conditions. The evolution of bipedalism in our human ancestors is largely to blame, says Jeremy DeSilva in "The Scars of Human Evolution."
Reports from Mars
Perchlorate, an energy source for bacteria on Earth, was discovered on Mars by the Phoenix mission, suggesting potential subsurface life on Mars. Samuel Kounaves and his colleagues also discovered what appears to be perchlorate in a Martian meteorite that landed in Antarctica.
Machines that Communicate with the Body
An "electronic tattoo" can be used to better monitor women in labor, seizure-prone infants and other patients. As small as a postage stamp and as thick as a human hair, Todd Coleman explains a non-invasive technology that tracks the electrical rhythms on the surface of the body.
