This breakthrough technology promises to vastly improve the wireless communications capabilities of everything from 5G mobile technology to the multitude devices aimed at supporting the Internet of Things."

According to the developer, who describes himself as an an addicted kiter, helicopter and jet pilot: "Windyty.com is advertisement free and a strictly non-commercial project. GFS forecast model, produced by NOAA, is the major source of weather data."
The maps are simultaneously beautiful and useful for people who need to know what the wind is or will be doing.

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.

From the article:
"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."

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."

"HPN has assembled data on 100,000 patients, which it will be sharing with contest entrants. ("It's all HIPAA-compliant," assures Gluck; the patients cannot be reidentified.) Lab data, prescription information, treatment plans--it's all there. "Teams then look at the data and create an algorithm that says, in the year following the data, did they wind up going to hospital?" Since the data is all from a few years back, the answers are available, so the coders can test themselves."
overThruster writes: The Wall Street Journal and Defense News report that China had more than 25 different unmanned aerial vehicles (UAVs) on display at the Zhuhai Airshow. 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."

There are also rumors of a desire of internal factions at Microsoft to oust him due to poor stock performance.

Since when should a voting machine check *any* candidates name by default? Link to Original Source
overThruster 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

All I've found on the subject are these blog entries. It would be interesting to hear whether fellow slashdotters know any more about their demise and whether there is any chance they will be coming back.
