Rarely has a single food gotten such star treatment as the hamburger that made its debut in London on Monday. But the burger — grown from stem cells taken from a cow — represents a technology potentially so disruptive that it has attracted the support of Google co-founder Sergei Brin.

Paleontologists have been spending a lot of time studying the Earth of 50 million years ago, which was much hotter than it is today. They're hoping a glimpse into the planet's geologic past will show them how the planet will respond to all the carbon dioxide we're now putting into the air.
