Ancient Life ‘Re-Evolves’ in Georgia Lab
Georgia Tech researchers say they’ve resurrected a 500-million-year-old gene from bacteria and inserted it into modern-day Escherichia coli (E. coli) bacteria. The resurrected bacterium has been growing for more than 1,000 generations, providing scientists a chance to observe evolution in action, the university announced. “This is as close as we can get to rewinding and…

What’s a Lake Doing in the Middle of the Desert?
One place you don’t expect to see waves lapping against the shore is in the middle of a desert.

A diminutive, hobbitlike people called Homo floresiensis inhabited Indonesia. What were essentially modern humans roamed Africa. Then, about 60,000 years ago, a…
