Quantum Cascade Laser Nanoantenna Created

In a major feat of nanotechnology engineering researchers have demonstrated a laser with a wide-range of potential applications in chemistry, biology and medicine. Called a quantum cascade laser nanoantenna, the device is capable of resolving the chemical composition of samples, such as the interior of a cell, with unprecedented detail. The new laser could lead to ultrahigh resolution microscopes...

Production Delay Puts OLPC in Tight Squeeze

The One Laptop Per Child project was supposed to start production in October, but due to "last-minute bugs," the bulk of production has been delayed until November 12. That means the project will have trouble delivering laptops to children in Uruguay and Peru, the only countries that have ordered the machines so far, in time for kids to use them over their summer vacation. And while OLPC still...

Space Shuttle Discovery Docks with ISS

Space shuttle Discovery docked with the international space station on Thursday, and its crew prepared to embark on the most challenging construction work ever attempted in a single mission. With commander Pamela Melroy at the helm, Discovery snuggled up to the space station and latched on after performing a giant somersault to give engineers a close look at the ship's belly and make sure it...

Controversial DNA Scientist James Watson Retires

James Watson, the Nobel laureate who sparked an international furor last week with comments about intelligence levels among blacks, has retired from his post at a prestigious research institution. Watson, 79, and the Cold Spring Harbor Laboratory in New York announced his departure Thursday. Watson was chancellor of the institution, and his retirement was effective immediately. Watson...

Brain's Optimism Center Is Identified

A person's optimism in the future seems to be controlled by a small front part of the mid-brain, according to a study that used brain imaging. That area deep behind the eyes activates when people think good thoughts about what might happen in the future. The more optimistic a person is, the brighter the area showed up in brain scans, the scientists reported in a small study published online...

House Testing Revised Kids' Health Bill

House members are about to learn whether some nips and tucks to a children's health bill will be enough to secure a veto-proof margin against a White House that wants major surgery. The House planned to vote Thursday on a modestly revised version of a bill that President Bush vetoed Oct. 3. Last week the House fell 13 votes short of the two-thirds majority needed to override the veto, which...

NYC Tries To Get Calories on Menus

Burger joints beware: New York's calorie crusaders are at it again. City health officials announced Wednesday that they hope to revive their stalled plan to force fast-food chains to add calorie counts to the big menu boards that hang above their counters. The city's original effort to put calories on menus was struck down by a judge in September, but Health Commissioner Thomas Frieden said...
