Eco-engineers in the Netherlands are taking hints from nature to rein in flooding. One idea is to plant trees in front of dikes to lower the height of approaching waves. They compare this type of approach to judo—they are using the forces of nature, rather than fighting against them, to produce powerful results. Funding for NOVA is provided by David H.

Witnesses to JFK's assassination heard three shots, and police found three cartridges in Oswald's perch. Nevertheless, only two bullets were ever found. Could this missing bullet have hit a tree or the pavement? And if so, why was it never located? Forensics experts Luke and Mike Haag perform tests with a Carcano rifle to solve the mystery of the missing bullet. National corporate funding for NOVA is provided by The Boeing Company.

Since 1972, a company called Alcor has been preserving legally dead people at very low temperatures. The hope is that in the future, scientists will be able to revive these "patients," giving them a chance for eternal life. It may sound like the stuff of science fiction, but host David Pogue met with Alcor president and CEO Max More to tour the facility and learn about the field of "cryonics."

Researchers who've studied Einstein's brain have long known that parts of his parietal lobe—a part of the brain involved in spatial imagination—were unusually large. But now, a collection of 14 photographs missing since 1955 have revealed that Einstein's right frontal lobe has four ridges instead of the standard-issue three, giving him more brain power. And, in an unusual twist, it turns out that the host of NOVA scienceNOW, David Pogue, shares this same trait. Funding for NOVA scienceNOW is provided by the National Science Foundation, the Alfred P.
