Corey Powell furthers Brandon Carter's famous 'Doomsday Argument' by listing 20 ways in which the world could end.

An introduction to artificial life with a focus on genetic algorithims and evolutionary computing. "Computers can now mimic evolution by breeding software that can design robots, improvise jazz, manage vast warehouse inventories, and tackle other creative tasks more efficiently than humans. Are these digital powerhouses too smart for our own good?"

How astrophysicists have finally learned to exploit high-powered lasers and searing plasma in a laboratory setting to simulate the most violent features in the heavens, including the blast waves that radiate from supernova explosions and the birth wails of newborn stars.

Maverick energy guru Amory Lovins says a profitable, pollution-free hydrogen economy is just over the horizon. It's merely a matter of taming the most powerful gas on the planet, hydrogen.

A critical look at the science and technology required to build an antiballistic system that would make the United States invulnerable to a missile attack.

Orbital space around the Earth is full of deadly debris from old missions. Now NASA has to figure out how to keep a hail of space junk from bringing down the shuttle, the space station, and a lot of satellites.

A report on efforts at Caltech to develop a quantum computing network. Article has an excellent layperson introduction to quantum computing.

Researchers have developed an efficient process to convert organic solids into liquid fuel. The process, thermal depolymerization process, is designed to take almost any waste product imaginable and turn it into one of three products, all valuable and environmentally benign: high-quality oil, clean-burning gas, and purified minerals that can be used as fuels, fertilizers, or specialty chemicals for manufacturing.

Widely available high-resolution commercial satellite imagery is making governments around the world awfully nervous.
