Can We Build Tomorrow's Breakthroughs?
Manufacturing in the United States is in trouble. That's bad news not just for the country's economy but for the future of innovation.
The Rare-Earth Crisis
Today's electric cars and wind turbines rely on a few elements that are mined almost entirely in China. Demand for these materials may soon exceed supply. Will this be China's next great economic advantage?
Silicon and Sun
In his lab facing the Pacific Ocean, Daniel Morse is learning new ways to build complex semiconductor devices for cheaper, more efficient solar cells. He has an unlikely teacher: sea sponges.
Super Soldiers
Nano materials could provide future soldiers with super strength, protection against bioweapons and even a way to communicate covertly.
Nanotech by the Numbers
It's virtual reality, writ small: atom-by-atom simulations of new materials could usher in the nanotech future sooner than anybody imagined.
Wires of Wonder
Nobelist Smalley explains how "carbon nanotubes" will affect everything, from living cells to electrical transmission.
Will the Real Nanotech Please Stand Up?
Researchers are building devices one molecule at a time. TR sorts the possible form the preposterous.
Winning Combinations
Combinatorial chemestry has revolutionized drug developmnet. A handful of startup companies are betting it can do the same in the search for new materials
