What Would Happen if I Ate a Teaspoonful of White Dwarf Star?
“Everything about it would be bad,” says Mark Hammergren, an astronomer at Adler Planetarium in Chicago, beginning with your attempt to scoop it up. Despite the fact that white dwarfs are fairly common throughout the universe, the nearest is 8.6 light-years away. Let’s assume, though, that you’ve spent 8.6 years in your light-speed car and that the radiation and heat emanating from the star didn’t kill you on your approach. White dwarfs are extremely dense stars, and their surface gravity is about 100,000 times as strong as Earth’s. “You’d have to get your sample—which would be very hard to carve out—without falling onto the star and getting flattened into a plasma,” Hammergren says.Intel Wants Brain Implants in Its Customers' Heads by 2020
If the idea of turning consumers into true cyborgs sounds creepy, don't tell Intel researchers. Intel's Pittsburgh lab aims to develop brain implants that can control all sorts of gadgets directly via brain waves by 2020.
Google's Replacement for HTTP Protocol to Make Web Browsing Twice as Fast
Google has scarcely stopped for a breather since launching its cloud-based Chrome OS as an alternative to PC and Mac operating systems. Now its Chromium group has announced an effort to replace the traditional HTTP web browser language with a new protocol that supposedly boosts Internet browsing by up to 55 percent.
HTTP currently is the protocol used by all web servers and browsers, hence the "http" in front of web addresses. But, as noted by Ars Technica, HTTP becomes inefficient when transferring many small files on many modern websites.
By contrast, Google's cleverly named SPDY protocol (pronounced SPeeDY, get it?) can compress and handle the individual requests via one connection that's SSL-encrypted. That allows higher-priority files to slip through immediately without becoming backed up behind large files.
SPDY has shown up to 55 percent web page loading when tested under lab conditions, and the Google team has released their source code for public feedback.
But Ars Technica raises some points of caution about the mandatory SSL encryption requiring more processing power from small devices and computers alike. Requiring SSL could also worsen the problem where server operators neglect SSL encryption and unintentionally encourage people to ignore warnings about unsecured websites.
Still Google's team recognizes these problems and has already proposed workaround solutions. An open approach has already proven a smashing success on Google's Android operating system, but redesigning the Internet's architecture will undoubtedly prove trickier in the days to come.
IBM's Blue Gene Supercomputer Models a Cat's Entire Brain
Using 144 terabytes of RAM, scientists simulate a cat's cerebral cortex based on 1 billion neurons and 10 trillion synapses.
Cats may retain an aura of mystery about their smug selves, but that could change with scientists using a supercomputer to simulate the the feline brain. That translates into 144 terabytes of working memory for the digital kitty mind.
IBM and Stanford University researchers modeled a cat's cerebral cortex using the Blue Gene/IP supercomputer, which currently ranks as the fourth most powerful supercomputer in the world. They had simulated a full rat brain in 2007, and 1 percent of the human cerebral cortex this year.
The simulated cat brain still runs about 100 times slower than the real thing. But PhysOrg reports that a new algorithm called BlueMatter allows IBM researchers to diagram the connections among cortical and sub-cortical places within the human brain. The team then built the cat cortex simulation consisting of 1 billion brain cells and 10 trillion learning synapses, the communication connections among neurons.
A separate team of Swiss researchers also used an IBM supercomputer for their Blue Brain project, where a digital rat brain's neurons began creating self-organizing neurological patterns. That research group hopes to simulate a human brain within 10 years.
Another more radical approach from Stanford University looks to recreate the human brain's messily chaotic system on a small device called Neurogrid. Unlike traditional supercomputers with massive energy requirements, Neurogrid might run on the human brain's power requirement of just 20 watts -- barely enough to run a dim light bulb.
U.S Telecom Firms Get to Keep Company Data
Telecommunications providers like Verizon and Comcast feared they would have to reveal revenue per customer and the Internet speeds they offer in an effort to map U.S. broadband use.
Telecommunications providers will not have to give the government sensitive revenue and Internet speed data for a program to map broadband use in U.S. homes and bring high-speed Internet service to more people.
The U.S. Commerce Department said on Friday that companies such as Verizon Communications, Comcast and AT&T do not have to share how much money they make from each Internet subscriber. Nor must they say how fast their Internet connections typically run.
Instead, they will provide data by the block, usually about a dozen homes depending on the size of the block. They also will share the speed of Internet service that they advertise.
Companies do not want to share the specific data because they do not want their competitors to see it.
But failing to make it public allows the companies to advertise—and charge for—something that they often cannot deliver, said Joel Kelsey, a telecom policy analyst at Consumers Union, a watchdog group.
"The actual speeds delivered to particular areas simply doesn't match up," Kelsey said. "The government gave a lot and received very, very little in return."
Companies that sell Internet service advertise maximum service speeds as a way to entice customers. More speed means faster access to online entertainment and information.
Internet connections can work at slower speeds than the maximum speed advertised, especially when many subscribers are online at the same time.
The American Cable Association and other groups representing the companies opposed some of the rules before the government clarified the data policy.
"The agency's modifications will improve and expedite (the mapping) effort," ACA President Matthew Polka said.
Larry Landis, an Indiana utility regulatory commissioner and chairman of the federal-state group that will map high-speed Internet availability, praised the Commerce Department's National Telecommunications and Information Administration for being flexible.
The Commerce and Agriculture departments will award loans and grants to state and local governments, and nonprofit and for-profit companies, including telecommunications companies, to participate in the government's broadband program.
The first phase of the plan would release $4 billion of the $7.2 billion program included in President Barack Obama's economic stimulus plan. About $350 million will go to the mapping program, but the Commerce Department estimated that $240 million would be needed.
The rule changes come a day after the Federal Communications Commission launched its first workshop to gather ideas and proposals for a national broadband plan it plans to give to Congress in February.

computer-aided design
computer-aided design (CAD) or computer-aided design and drafting (CADD), form of automation that helps designers prepare drawings, specifications, parts lists, and other design-related elements using special graphics- and calculations-intensive computer programs. The technology is used for a wide variety of products in such fields as architecture, electronics, and aerospace, naval, and automotive engineering. Although CAD systems originally merely automated drafting, they now usually include three-dimensional modeling and computer-simulated operation of the model. Rather than having to build prototypes and change components to determine the effects of tolerance ranges, engineers can use computers to simulate operation to determine loads and stresses. For example, an automobile manufacturer might use CAD to calculate the wind drag on several new car-body designs without having to build physical models of each one. In microelectronics , as devices have become smaller and more complex, CAD has become an especially important technology. Among the benefits of such systems are lower product-development costs and a greatly shortened design cycle. While less expensive CAD systems running on personal computers have become available for do-it-yourself home remodeling and simple drafting, state-of-the-art CAD systems running on workstations and mainframe computers are increasingly integrated with computer-aided manufacturing systems.
