Driving simulation tests suggest that human memory, rather than negligence, may be responsible for "looked, but failed to see" collisions, a new study suggests.

Ever older remains of early migrants rewrite the story of the first North Americans

Artifacts dated to roughly 16,000 years ago mean migrants didn't wait for the ice age to end
