Anthropology

The Human Wave

Anatomically modern people evolved in small groups of ancient Homo sapiens that never traveled too far but continually interbred with nearby groups, including other Homo species, creating a genetic wave that moved from Africa across Asia, a new model suggests.

Tech

Easy Striders

New robots based on the mechanics of human walking use less energy and move more naturally than traditional bipedal robots do, suggesting new ways to approach two-legged robots and prosthetic design.

Humans

Pharmaceutical marketing toward both patients and physicians appears to influence which medicines get prescribed.

Archaeology

Seeing Past the Dirt

Increasingly, researchers are using geophysical techniques such as ground-penetrating radar and magnetometers to target their excavations.
