A manned solar-powered airplane took off in the early hours of Wednesday morning for a 24-hour trip that will include its first nighttime flight. After being postponed last week, the flight began at 6:51 a.m. local time, when the Solar Impulse HB-SIA aircraft took off from the Payerne airbase in Swi...
Personal computing altered the world forever, and now the digitization of biology is poised to bring about sweeping change. Craig Venter's recent announcement of the first synthetic genome was a huge milestone, but many outside of Silicon Valley remain unaware of the "do-it-yourself biology" movemen...
The Obama administration on Monday released a new space policy for the U.S. that emphasizes international cooperation and the advancement of the commercial space industry. "No longer are we racing against an adversary; in fact, one of our central goals is to promote peaceful cooperation and collabor...
These are not your grandpa's greenhouses. Anyone familiar with common plastic-enclosed passive solar structures designed simply to hold plants over cold seasons or grow flowers and less-hardy fruits might be surprised about how these humble buildings have transformed into today's dynamic hydroponic ...
The farm has moved to the city in the form of rooftop hydroponic greenhouses, leaving the dirt and pests and pesticides behind in the rural field and going high-tech with a penthouse view from perches atop old buildings. Restaurants, converted factories and warehouses, government facilities, the sto...
There are multiple underwater oil plumes in the area surrounding BP's broken wellhead off the coast of Louisiana, but so far their concentrations seem to be "very low," according to a report released Tuesday by NOAA. Scientists analyzed water samples collected by the University of South Florida's R/...
Researchers at the J. Craig Venter Institute in Rockville, Md., say they have created the first self-replicating synthetic bacterial cell using man-made DNA. The 15-year, $40 million project consisted of synthesizing more than 1 million base pair chromosomes of a genome. The knowledge gained from th...
A mind-controlled robotic arm is bringing new independence to an Austrian man who lost his arms, even allowing him to drive a car, the arm's maker announced earlier this week. Created by the German firm Otto Bock HealthCare, the arm has allowed 23-year-old Christian Kandlbauer to pass a driving test...
The quarrel over who uses the most -- or least -- harmful chemicals to make computer components seems to be dying down. In its place comes a debate over which companies are doing the best job to create and forward an agenda addressing global warming -- not just for themselves, but for the companies ...
"Avatar" director James Cameron is working with NASA on two 3-D cameras that could be used on the next Mars rover, known as "Curiosity." Earlier this month, Malin Space Science Systems delivered two cameras, known as "MastCams," that are similar but lack the 3-D capabilities. If the new pair develop...
During his homily this Easter, Pope Benedict argued that medical science, in trying to defeat death, is leading humanity toward likely condemnation. It's a position at odds with the value of life, one that the Church will likely revise years from now, replaying the institution's embarrassment over c...
Twenty years ago Saturday, the Hubble Space Telescope was launched into low Earth orbit, beginning its journey to become NASA's best-recognized, longest-lived and most prolific space observatory. To celebrate the milestone, NASA, the European Space Agency, and the Space Telescope Science Institute r...
IBM researchers in Switzerland said they've come up with a patterning technique that lets them create structures as small as 15 nanometers. One nanometer is a millionth of a millimeter. In comparison, a human hair is between .03 and .25 mm thick. Using the nanopatterning technique, the researchers h...
Two months after the launch of NASA's Solar Dynamics Observatory, its first images are now arriving back on Earth with more detail about the sun than has ever been seen before. Some of the images from the spacecraft reveal in new clarity the material streaming outward and away from sunspots. Others ...
Up to now, devices designed to measure and enhance signals routed through brain circuitry have been hampered by the complexities of the folded surface of brain tissue. However, scientists have announced the development of a brain implant that conforms so closely to the brain's surface, it "essential...
