Brains Work Best At Age of 39 267

Scientists at the University of California Los Angeles are reporting that while some people may think "life begins at 40," all it seems to do is slow down. According to recent research, at age 39 our brain reaches its peak speed, and it's all downhill after that. "The loss of a fatty skin that coats the nerve cells, called neurons, during middle age causes the slowdown, experts say. The coating acts as insulation, similar to the plastic covering on an electrical cable, and allows for fast bursts of signals around the body and brain. When the sheath deteriorates, signals passing along the neurons in the brain slow down. This means reaction times in the body are slower too."

NASA Uses Rubber Ducks In Climate Study Screenshot-sm 33

NASA researchers have dropped 90 rubber ducks into holes of Greenland's fastest moving glacier: the Jakobshavn Glacier in Baffin Bay. Scientists are unsure as to why glaciers speed up in the summer months. One theory is that the summer sun melts ice on the surface of the glacier, which creates pools of water, which then flow into moulins -- narrow tubular shafts in the glacier. These then transport the water from the top to the underside of the glacier. The rubber ducks, labeled with the words "science experiment" and "reward" in three languages, along with an email address, may provide some answers. It is hoped that in addition to bath time, the ducks can make a livable climate lots of fun.

Apple Declares DRM War On Sneaker Hackers 330

theodp writes "Nicholas Carr is not pleased that Apple has applied for a patent to extend DRM to tennis shoes and other articles of clothing. Apple apparently views tennis-shoe DRM as a way to head off a potential plague of sneaker hacking. 'Some people,' the patent application observes, 'have taken it upon themselves to remove the sensor from the special pocket of the [iPod-linked] Nike+ shoe and place it at inappropriate locations (shoelaces, for example) or place it on non-Nike+ model shoes.'"

World's First "Unclonable" RFID Chip 320

An anonymous reader writes to tell us that a new RFID chip from Verayo claims to be unclonable through the use of the new Physical Unclonable Functions (PUF), sort of an electronic DNA for silicon chips. "Basic passive RFID chips can be easily cloned by copying the data residing on one chip to another. Verayo's PUF-based RFID chips cannot be cloned, and provide a very strong and robust authentication mechanism. No other chip or device can be disguised as the original chip, even if the data is copied from one Verayo RFID chip to another."

Ghostbusters Is First Film Released On USB Key 448

arcticstoat writes "Are you the USB keymaster? You could be soon if you pick up PNY's new 2GB USB flashdrive, which comes pre-loaded with Ghostbusters. A spokesperson for PNY explained that it comes with a form of DRM that prevents you from copying the movie. 'They have DRM protection,' explained the spokesperson, 'so customers can download the movie onto their laptop or PC if they wish, but they have to have the USB drive plugged in to watch the movie, as the DRM is locked in the USB drive.' The music industry has been playing around with USB flash drives for a few years now, but it hasn't been a massive success yet; will USB movies fare any better?"

Paralyzed Man Walks Again Using Exoskeleton 192

dominique_cimafranca notes a story up at the Daily Mail in the UK about a partially paralyzed man who is able to walk again using an exoskeleton frame. The article goes a bit far in comparing the device to Robocop, but it does show pictures of the man, paralyzed for the last 20 years, regaining some use of his legs. Quoting: "The device, called ReWalk, is the brainchild of engineer Amit Goffer, founder of Argo Medical Technologies, a small Israeli high-tech company. Something of a mix between the exoskeleton of a crustacean and the suit worn by Robocop, ReWalk helps paraplegics — people paralyzed below the waist — to stand, walk and climb stairs. The system, which requires crutches to help with balance, consists of motorized leg supports, body sensors and a back pack containing a computerized control box and rechargeable batteries."

Terror Watchlist "Crippled By Technical Flaws" 324

I Don't Believe in Imaginary Property writes "The database used by the government to generate lists like the No-Fly List is 'crippled by technical flaws,' according to the chairman of a House technology oversight subcommittee. And the upgrade may be worse than the original. Rep. Brad Miller (D-NC) says that 'if actually deployed, [the upgrade] will leave our country more vulnerable than the existing yet flawed system in operation today.' It seems that the current database doesn't have any easy way to do plain-text matching, forcing users to enter SQL queries. That might not sound so bad until you learn that the database contains 463 poorly indexed tables. How long until there's a terrorist named Robert'); DROP DATABASE; —?"

Carbon-Neutral Ziggurat Could House 1.1 Million In Dubai 393

Engadget is reporting that a new pyramid-shaped city of the future, dubbed a "Ziggurat," is being touted by Dubai-based environmental design company, Timelinks. Claiming that their design allows for an almost self-sufficient energy footprint and, obviously, economy of space, the real trick would be getting 1.1 million people to live in such close proximity. "Martijn Kramer, managing director of The International Institute for the Urban Environment told WAN: 'As a general reaction the Ziggurat Project is viable from a technical point of view. However reflecting from a more sustainable holistic approach we do wonder if the food supply and waste system are taken care for, as the concept seems rather based upon carbon neutrality and energy saving.' Kramer's initial reaction to 'Ziggurat' also raises a very important issue: are people willing to live in a mega building of 2.3 sq km? Will the thought of living in a machine comfort people?"

San Francisco DA Discloses City's Passwords 333

snydeq writes "The office of San Francisco District Attorney Kamala Harris has made public close to 150 usernames and passwords used by various departments to connect to the city's VPN. The passwords were filed this week as Exhibit A in a court document arguing against a reduction in $5 million bail in the case against Terry Childs. Though they placed the passwords in the public record, city prosecutors do seem to think that they are sensitive. InfoWorld's Paul Venezia, who has been following the case closely, provides further analysis of the technical details in the city's case. 'By themselves, [the passwords] would not be enough to allow anyone to access the network via VPN,' Venezia writes, 'but the fact that the city entered them into evidence is quite shocking. At the very least, they'll have to shut down their VPN access for awhile until they've changed them all and modified the configurations of some large number of VPN clients.'"

Apollo 14 Moonwalker Claims Aliens Exist 1268

An anonymous reader writes "Former NASA astronaut and moon-walker Dr Edgar Mitchell — a veteran of the Apollo 14 mission — has stunningly claimed aliens exist. And he says extra-terrestrials have visited Earth on several occasions — but the alien contact has been repeatedly covered up by governments for six decades. Dr Mitchell, 77, said during a radio interview that sources at the space agency who had had contact with aliens described the beings as 'little people who look strange to us.'"

Submission + - Admin Locks Out City Officials from S.F. Network

statemachine writes: "A disgruntled city computer engineer has virtually commandeered San Francisco's new multimillion-dollar computer network, altering it to deny access to top administrators even as he sits in jail on $5 million bail. Prosecutors say [Terry] Childs, who works in the Department of Technology, tampered with the city's new FiberWAN, where records such as officials' e-mails, city payroll files, confidential law enforcement documents and jail inmates' bookings are stored."

Boeing-Skyhook Airship Faces Technical Challenges 185

waderoush writes "Since the Hindenburg disaster, dreams of giant airships capable of lifting heavy cargo have been restricted mainly to Popular Science covers (with the notable exception of the Cargolifter AG failure) — until Boeing and a Canadian company called Skyhook announced on July 8 that they're building a 300-foot-long, helium-filled craft that will lift loads of up to 40 tons and carry them 200 miles. But an aeronautical engineer at the University of Washington cautions that there are still some big problems to be worked out with mega-airships, including their stability in turbulent weather."

MediaDefender's BitTorrent-Based DOS Takes Down Revision3 426

Sandman1971 writes "Over the long Memorial Day weekend, Revision3 was the target of a malicious Denial Of Service Attack which brought R3 to its knees. After investigating the matter, it was discovered that the source of the attacks came from MediaDefender, the famed company hired by the MPAA and RIAA to try and stop the spread of illegal file sharing. The kicker? Revision3 was taken down for running a bittorent tracker to distribute its own legal content."

Google's Street View Meets Resistance In France 201

Ian Lamont writes "Google has begun to scan the streets of Paris as part of its Street View service, but the company may be hindered from publishing them unedited. The reason? French privacy laws. Google may be forced to blur faces or use low-resolution versions of the photographs. The Embassy of France in the US has a page devoted to French privacy laws, that says the laws are needed to 'avoid infringing the individual's right to privacy and right to his or her picture (photograph or drawing), both of them rights of personality.'"
