Are We Alone for 01/26/09 - Carbon Your Enthusiasm




Are We Alone - "Carbon Your Enthusiasm"
Bond it to oxygen and it’s the scourge of climate change. But earthly life wouldn’t be possible without carbon, and maybe that’s true for alien life, too.

And carbon has other exciting forms: tiny diamonds may be evidence of a catastrophic comet impact 13,000 years ago. And, chalky carbonates may point to a once-habitable Mars.
So get cozy with carbon. Find out if you could swap it for silicon in DNA. Plus, the conundrum of calculating a carbon footprint.

Are We Alone for 01/19/09 - You Animal!




Are We Alone - Encore Presentation "You Animal!"
Maybe Dr. Doolittle was on to something; animals are smarter than we think. Birds, apes, and dolphins are all clever problem solvers with a rich vocabularly and - in some cases - self-awareness. Find out what you can learn from our furry, finned and feathered friends. Also, why you are so much an animal yourself, all the way down to the bare bones.

Plus, enter the locked vaults that hold extinct and newly-discovered animal species. And why B-movie critters steal the show.
(A new species? This is a grey-faced sengi. Click here for another photo.)

Are We Alone for 01/05/09 - Sex: From Beginning to End


Are We Alone

Are We Alone - Encore Presentation "Sex: From Beginning to End"
We all know how sex begins: a dimly-lit room, a come-hither smile, and a surfeit of parasol-shaded cocktails. But long before all that, the gentle currents of the ancient sea floor set the mood. It was there, 570 million years ago, that two ropy sea creatures found each other and changed the course of evolution.

Hear how sex began and where it's headed: if you think your love life is mechanical now, just wait until you're cozying up to titanium skin and the latest emotion software.

Plus, everything you always wanted to know about modern sex research, but were afraid to ask.
