Kenneth Nealson Kenneth Nealson's discoveries defy long-held assumptions Member Spotlight May 19, 2014 When you step into Kenneth Nealson's lab, it would be normal to look around for the bench where his research is done.

Elizabeth Reitz is unearthing ancient cultures Elizabeth Reitz is unearthing ancient cultures Member Spotlight February 20, 2014 More than a clay pot, more than a crumbling ancient building, a bone can sometimes speak to the secrets of history. Anthropologist Elizabeth Reitz has discovered that biological clues can help reveal what species of animals a population raised and ate, how their culture was inspired by food choices, and the technologies they developed to access different sources of nourishment. And, she says, bones can divulge even more.

AAAS Annual Report 2012 AAAS Annual Report 2012 Monday, June 24, 2013 The latest AAAS Annual Report is now available online at A hike back in geological time A hike back in geological time AAAS Serves May 30, 2013 If a single human stride (0.75 meters/.82 yards) is equivalent to 60,000 years, then 6.25 centimeters (2.46 inches) represents the duration of human civilization, which is only 5,000 years old. That means a 12.5-kilometer (7.7-mile) hike would cover approximately one billion years of evolutionary time, back to the beginning of multi-cellular life on Earth. But who would make such a calculation and why? Kevin Saldanha did. He’s a veterinarian in Ontario, Canada, and the founder of the Ancestor’s Trail Hike in Mississauga, Ontario.
