overThruster (58843) writes "livescience.com reports: Blu-ray discs could help make the solar cells used in solar panels more efficient, researchers say.
Prior research had revealed that if microscopic structures that are only nanometers (billionths of a meter) high are placed on the surface of solar cells, they can scatter light in ways that increase the cells' efficiency. The best patterns of nanostructures to place on solar cells are quasi-random ones — patterns that are neither too orderly nor too random.
The researchers used a Blu-ray of "Police Story 3: Supercop," starring Jackie Chan, to create a mold for a quasi-random surface texture that they placed on a solar cell. They found that this pattern boosted light absorption significantly — by 21.8 percent over the entire solar spectrum, more so than either a random pattern or no pattern." top
New chemical process could make ammonia a practical car fuel
"Many catalysts can effectively crack ammonia to release the hydrogen, but the best ones are very expensive precious metals. This new method is different and involves two simultaneous chemical processes rather than using a catalyst, and can achieve the same result at a fraction of the cost."
"Professor Bill David, who led the STFC research team at the ISIS Neutron Source, said "Our approach is as effective as the best current catalysts but the active material, sodium amide, costs pennies to produce. We can produce hydrogen from ammonia 'on demand' effectively and affordably.""
"Ammonia is already one of the most transported bulk chemicals worldwide. It is ammonia that is the feedstock for the fertilisers that enable the production of almost half the world's food. Increasing ammonia production is technologically straightforward and there is no obvious reason why this existing infrastructure cannot be extended so that ammonia not only feeds but powers the planet."" top
overThruster (58843) writes "After years of trying, Japanese scientists have captured live video of the giant squid in its natural habitat. The squid was filmed at a depth of 2066 feet, 9.3 miles (15 kilometres) east of Chichi Island, a small archipelago about 150 miles (241.4 kilometers) north of Iwo Jima. The video will air on January 27th on the Discovery Channel.
Tsunemi Kubodera, the mission leader:
“It was shining and so beautiful. I was so thrilled when I saw it first hand, but I was confident we would because we rigorously researched the areas we might find it, based on past data. Researchers around the world have tried to film giant squid in their natural habitats, but all attempts were in vain before.”

Not so fast. CNET reports that law enforcement agencies have known about this data for some time and have been using a commercial product to extract it for use in forensic investigations of crimes.
From the article: "The information on the phone is useful in a forensics context," Levinson told CNET today. Customers for Lantern 2, he said, include "small-town local police all the way up to state and federal police, different agencies in the government that have forensics units."" top

Lab data, prescription information, treatment plans--it's all there.

Since the data is all from a few years back, the answers are available, so the coders can test themselves."" top

In addition to a jet powered UAV that is potentially faster than U.S. made drones such as the Predator and Reaper, the Chinese have developed an unmanned "thopter" for surveillance. "ASN showed off 10 different UAVs, including the new ASN-211 Flapping Wing Aircraft System, which simulates a bird in flight. The prototype on display has a take-off weight of only 220 grams with a maximum speed of six-to-10 meters a second and an altitude ranging from 20-200 meters. A spokesperson said the micro-UAV would mainly be used for low-altitude reconnaissance for troops in the field."" top

Symantec To Buy VeriSign's Authentication Business
overThruster (58843) writes "Security giant Symantec is taking another step toward global domination of the information security market with the purchase of VeriSign's authentication business. Back in April they purchased PGP Corporation and GuardianEdge. VeriSign is the best known Certificate Authority; they are virtually synonymous with certificates for SSL and PKI. It seems like this could dilute the trust value of their brand rather than enhance it. It is not clear yet what effects this will have on VeriSign customers but the cynic in me says it can't be good. In terms of putting all your eggs in one basket, this will sure make Symantec a juicy target for hackers (as if they weren't already.) Imagine you could hack one company and control a large chunk of endpoint security software and the bulk of the Internet's public key infrastructure." Link to Original Source top

What's interesting is the highly efficient propulsion system which uses a "tail" modeled after CAT scans of a dolphin's. From the article:
"Ciamillo and Fish say they knew they were onto something when the first prototype Lunocet, a piece of sculpted foam sandwiched between two pieces of carbon fibre, essentially swam by itself. When they released it at the bottom of a test pool, its buoyancy combined with its cambered shape generated a forward thrust that made it scoot across the tank."" top
overThruster (58843) writes "By default, Vista does not require a password when resuming from hibernation or suspend. Being a security geek, I turned this feature on only to discover that it only worked sometimes. After a bit of research, I found out that this feature needs to be turned on manually for every power management scheme that exists on a Vista machine! Furthermore, there is no global setting that can make this the default. This, coupled with a counter-intuitive UI that buries the setting makes it very likely that users wanting to password protect their machines on resume will think they have properly secured their machines when they haven't. This is a serious security design flaw and a step down from XP's security." top
overThruster (58843) writes "The Planetary Society reports that an asteroid tracked by NASA's Near Earth Object monitoring program will likely pass within 50,000 kilometers (30,000 miles) of Mars on January 30th, 2008. There is an estimated 1 in 75 chance of it striking the planet. If it does impact, it will hit a region close to NASA's Opportunity rover.
"Right now asteroid 2007 WD5 is about half-way between the Earth and Mars and closing the distance at a speed of about 27,900 miles per hour," said Don Yeomans, manager of the Near Earth Object Office at JPL. "Over the next five weeks, we hope to gather more information from observatories so we can further refine the asteroid's trajectory.""
