This will blow your mind
An old technology is providing new insights into the human brain. Electrocorticography, or ECoG, uses electrodes placed on the surface of the brain to detect electrical signals coming from the brain itself.
“This is both very exciting and somewhat frightening at the same time. It really goes pretty close to what people used to call mind reading.” — researcher Gerwin Schalk

iPad 2 as fast as a 1994 supercomputer?
The iPad 2 has been undergoing tests by Dr. Jack Dongarra, one of the computer scientists who keep track of the world’s fastest 500 supercomputers. At this stage his team have only tested one of the iPad 2’s twin cores, but have found that the tablet is around 10 times faster than the original model iPad.
He also estimates that when testing finishes, the iPad 2 will have a Linpack benchmark of between 1.5 and 1.65 gigaflops. That puts it at around the same speed of the Cray 2 supercomputer (pictured), which became the fastest in the world in 1985. At that speed it would also have continued to rank in the top 500 list until 1994. When you consider that the iPad 2 can do that at a much smaller size and with a power consumption possibly billions of times smaller than the Cray 2, it’s a great example of Moore’s Law in action.
Commencement season is arriving in this grand metropolis, the higher education capital of the world. Every graduate has a story. Tiffany Smalley’s just happens to be 346 years old.
She sat in a Harvard Square coffee shop one recent morning telling it in the understated way of hers, repeatedly talking about two young men, Caleb and Joel, Joel and Caleb, as if they might breeze through the door and start hashing over weekend plans.
The familiarity, even the affection, is understandable. They are all Wampanoag Indians, these three. They are accomplished people. They all left Martha’s Vineyard to prosper over four years at Harvard. There is, however, a key distinction: Caleb Cheeshahteaumuck and Joel Iacommes hark from the 1600s, while Tiffany, sipping a Frappuccino and rushing off to an internship, is every bit of the modern world.
Come May 26, the bond between Smalley and both her ancestors will come full circle. That is the day she will stride across the stage to accept a diploma and become the first Wampanoag to graduate from Harvard College since Caleb received his degree in 1665.
“The connection, recognizing those roots, is really important to feeling at home here,’’ Smalley said. “And I’ve felt really at home, knowing Caleb did this. It gives you perspective. He was just thrown into it, and for him, it was a whole different world.’’

Economists are warning that if Egypt’s turmoil continues much longer, the country will not have enough currency reserves to avoid a long term financial crisis.
Talk is cheap, but revolutions are expensive. Inside the economics of Egypt’s revolt.
The whole industry has come to equate more speed with 4G,” said Ralph de la Vega, chief executive of AT&T’s wireless unit. He says consumers generally won’t notice the difference in speed between AT&T’s HSPA-plus and upcoming LTE networks, so it makes sense to call both 4G.
- John Donovan, AT&T’s chief technology officer, said speeds on HSPA-plus and LTEphones will feel similar now, but users will start to notice a difference in the two technologies once richer applications become available.
