hakaii writes to tell us that the shells of tiny sea creatures may help to lay the foundation for new electronic devices including an improved pollution detector. "Using a chemical process that converts the shells' original silica (silicon dioxide, SiO2) into the semiconductor material silicon, researchers have created a new class of gas sensors based on the unique and intricate three-dimensional (3-D) shells produced by microscopic creatures known as diatoms. The converted shells, which retain the 3-D shape and nanoscale detail of the originals, could also be useful as battery electrodes, chemical purifiers - and in other applications requiring complex shapes that nature can produce better than humans."

narramissic writes "Canadian startup D-Wave's demonstration via Web link of a prototype quantum computer in mid-February was met with skepticism in the academic community, but NASA has confirmed that it did, in fact, build a special chip used in the disputed demonstration. According to an article on ITworld, D-Wave designed the quantum chip and then contracted with NASA to build it."

theodp writes "Reacting to a furor from some parents, advocacy groups, and public health experts, Merck said yesterday that it would stop lobbying state legislatures to require the use of its new cervical cancer vaccine Gardasil, which acts against strains of the sexually-transmitted human papilloma virus. The $400, 3-shot regimen was approved by the FDA in June. Later that month, a federal advisory panel recommended that females 11-26 years old be vaccinated. The governor of Texas has already signed an executive order making its use mandatory for schoolgirls."

henrypijames writes "The intense effort by the fair-use community to circumvent AACS (the content protection protocol of HD DVD and Blu-Ray) has produced yet another stunning result: The AACS Device Key of the WinDVD 8 has been found, allowing any movie playable by it to be decrypted. This new discovery by ATARI Vampire of the Doom9 forum is based on the previous research of two other forum members, muslix64 (who found a way to locate the Title Keys of single movies) and arnezami (who extracted the Processing Key of an unspecified software player). AACS certainly seems to be falling apart bit for bit every day now."

s31523 writes "Lawrence Livermore National Laboratory in California has announced they have working in the lab a Solid State Heat Capacity Laser that averages 67 kW. It is being developed for the military. The chief scientist Dr. Yamamoto is quoted: 'I know of no other solid state laser that has achieved 67 kW of average output power.' Although many lasers have peaked at higher capacities, getting the average sustained power to remain high is the tricky part. The article says that hitting the 100-kW level, at which point it would become interesting as a battlefield weapon, could be less than a year away."

Roland Piquepaille writes "Georgia Tech researchers have had a brilliant idea. Rocket engines used today to launch satellites run at maximum exhaust velocity until they reach orbit. For a car, this would be analog to stay all the time in first gear. So they have designed a new space rocket which works as it has a five-gear transmission system. This rocket engine uses 40 percent less fuel than current ones by running on solar power while in space and by fine-tuning exhaust velocity. But as it was designed with funds from the U.S. Air Force, military applications will be ready before civilian ones. Here is how this new rocket engine works."

slugo writes to mention a Wired article discussing a unique business looking to capitalize on interest in solar power. The Citizenr company will install a solar generator on your roof, completely for free. You then buy power from it, instead of a regular power company, at a fixed rate that's likely to be lower than the usual power fees. The company will make money on these usage fees, as well as credits from the federal government for spreading the use of solar power. If it sounds too good to be true to you, you're not alone. A number of financial analysts have warned people away from the company. "The naysayers are finding lots to say nay to. Much of the criticism is clinging to the company's multilevel marketing scheme. So far, more than 700 people have enlisted as independent Citizenr sales agents -- what the company calls 'ecopenuers' -- or about one sales representative for every 10 customers, with significant overlap. Heading that sales army is 42-year-old Styler, a veteran of multilevel marketing and a colorful figure in his own right." Pyramid marketing and shady business or not, it's an intriguing idea.

wiggles writes "According to the Chicago Tribune, the recent surge of video sites such as Youtube and Google video are pushing the limits of the Internet's bandwidth, or soon will be. Pieter Poll, chief technology officer at Qwest Communications, says that traffic volumes are growing faster than computing power, meaning that engineers can no longer count on newer, faster computers to keep ahead of their capacity demands. Further, a recent report from Deloitte Consulting raised the possibility that 2007 would see Internet demand exceed capacity. Admittedly, this seems a bit sensationalist, but are we headed for a massive slowdown of the whole internet?"
