And this month, a team of scientists will venture to the long-ice-buried expanse to investigate the mysterious ecosystem that was hidden beneath the Antarctic ice shelf for so long.

Week - News - Woodpeckers - Brain - Damage

This week’s strange news: woodpeckers with brain damage, cars in space, and a biomedical CEO using his own thigh as a guinea pig for an untested herpes treatment.

"The calving of [iceberg] A-68 [from the Larsen C Ice Shelf] provides us with a unique opportunity to study marine life as it responds to a dramatic environmental change. It's important we get there quickly before the undersea environment changes as sunlight enters the water and new species begin to colonize," Katrin Linse, of the British Antarctic Survey, said in a statement.

What lies beneath?

Scientists know little about the possibly alien-like life that has taken up residence beneath Antarctica's ice shelf. What they do know comes from similar calving events in the past: Chunks of ice broke off the Larsen A and B shelves (located north of Larsen C on the Antarctic Peninsula) in 1995 and 2002, respectively. Two German expeditions to those "newly"...
