Despite warnings to the contrary, Cyberdyne, SkyNet and Demon Seed are technological terrors that currently exist. No matter, as we've now got someone leading the fightback -- Skype co-founder Jaan Tallinn. He's part of a team of scientists, engineers and philosophers at Cambridge University's newly-minted Centre for the Study of Existential Risk. Aping the plot of beloved '70s TV series Doomwatch, the unit will investigate the fringes of science fact, including biotechnology, artificial intelligence and climate change. He'll be joined by Huw Price and Baron Martin Rees, who we hope will travel around the country in a minivan and fight ghosts, just like these guys.
