Ant Traffic Flow: Raiding swarms with few rules avoid gridlock
The 200,000 virtually blind army ants using a single trail to swarm out to a raid and return home with the booty naturally develop three traffic lanes, and a study now shows that simple individual behavior makes the pattern.

Chinese Roots: Skull may complicate human-origins debate
A Chinese Homo sapiens skull, estimated in a controversial new study to be at least 68,000 years old and probably more than 100,000 years old, may challenge the theory that modern humans originated solely in Africa.

Toppling icebergs sped breakup of Larsen B ice shelf
Scientists now think they know what accelerated the rapid disintegration of most of Antarctica's Larsen B ice shelf early this year after a strong summer storm pummeled the region.
