[Doomsday tech] Doomsday threats range from very real to controversial to futuristic. Witness amazing applications in the works, wonder at the limitless promise, and hear warnings of a possible nano-doomsday, with tiny, out-of-control machines devouring everything around them. Next, we stir up a hotter topic--the connection between global warming and fossil fuels--and ask if they're cooking up a sudden, new Ice Age. And we examine 21st-century technologies that typify the dual-edged sword of Doomsday Tech with massive potential for both creation and destruction--nanotechnology, robotics, and cybernetics."--Container.

[More doomsday tech] The second installment examines more threats--both natural and manmade--that may endanger civilization. From the far reaches of space to tiny viruses, doomsday sources are many. But so are the technologies used to keep doomsday at bay. Asteroid henters demonstrate the Near Earth Asteroid Tracking program and methods being developed to destroy earth-aimed asteroids. Then, it's onto bioterrorism's sinister technologies--how highly virulent agents like smallpox and plague can be weaponized. Next, we learn how vulnerable the nation's computers are to cyber-terror. Finally, we visit the controversial world of biotechnology."--Container.
