Imagine generating a living thing of your own design, to your own specifications. Recently, researchers have developed powerful new technologies that allow life to be built from scratch. New, engineered organisms are being constructed to help cure cancer, produce renewable energy, and assemble living computers. Teenagers can now learn to program DNA just as they learn to program computers. But who will control these new biotechnologies? What good and bad possibilities seem likely to come true?

Is ADHD an Advantage for Nomadic Tribesmen in Kenya?

A new study from Northwestern University's Weinberg College of Arts and Sciences suggests that the version of a gene associated with ADHD may actually prove beneficial for certain populations.

The study looked at the body mass index (BMI) and height of males from a tribe called Ariaal in northern Kenya. Some members of this tribe continue to live their traditional nomadic lifestyle, while others have recently settled and started to grow crops.
