Professor Robert McCaffrey and Research Associate Professor David Wark, of Renssleaer's Earth and Environmental Science department, will be featured on the National Geographic Channel's Naked Science program this week.

The episode is entitled "Stone Age Apocalypse" and deals with the super-volcano that the professors studied in Indonesia:

"Some 75,000 years ago a super-eruption from the site of Lake Toba in Sumatra blasted out more than two hundred cubic miles of ash over an area of over a million square miles. This programme investigates the devastating aftermath of the most powerful volcano of the last two million years - including the theory that it triggered a human genetic bottleneck leaving a tiny band, as low as a few thousand survivors to preserve the human race - and looks at the threat of super-volcanoes in the 21st century."

The episode airs Wednesday, February 28, 2007 at 9 p.m. as well as Thursday, March 1 at 12 a.m., and Saturday, March 3 at 4 p.m.
