Not only were the hESC-derived neurons capable of forming synaptic connections, they were able to correct memory and learning deficits.

drunken_boxer777 writes "The Wall Street Journal is reporting this morning that a proposed $100 million investment puts the value of Twitter at $1 billion. Despite the fact that Twitter has "yet to generate more than a trickle of revenue", this investment will allow the company "more time to figure out its business model". Given that many users are one-tweet wonders, does Twitter stand a chance at an actual revenue stream, ala Facebook, or without a coherent business plan will it go the way of MySpace?"

One of the latest entrants into the government spy-services marketplace, Palantir Technologies has designed what many intelligence analysts say is the most effective tool to date to investigate terrorist networks. The software's main advance is a user-friendly search tool that can scan multiple data sources at once, something previous search tools couldn't do. That means an analyst who is following a tip about a planned terror attack, for example, can more quickly and easily unearth connections among suspects, money transfers, phone calls and previous attacks around the globe.
A team of researchers working at the MR-Center of the University Children's Hospital in Zürich has completed a pilot study using transcranial MR-guided focused ultrasound to treat 10 patients with neuropathic pain.
"This research demonstrates that transcranial MR-guided focused ultrasound can be used non-invasively to produce small thermal ablations with extreme precision and accuracy deep in the brain," comments Neal Kassell, M.D.
The preliminary results in these patients are consistent with conventional therapy — radiofrequency ablation — which is an invasive procedure and involves making an incision in the scalp, drilling a hole in the skull, inserting an electrode through normal brain tissue into the thalamus, and using radiofrequency to create the lesion.

Buying electronic books on the Internet is easy — but so is taking them away.
That became clear last week when Amazon.com Inc. used its wireless technology to reach into customers' Kindle e-readers and deleted some e-books written by George Orwell. Amazon, which returned the cost of the e-books, said it made the move when it realized that the publisher didn't have the proper rights to sell the book in the U.S.
That didn't satisfy Antoine J. Bruguier, a 28-year-old engineer in Milpitas Calif., who was stunned to find his copy of "Nineteen Eighty Four" missing from his Kindle.

They had no television or Internet and their only link to the outside world was communications with the experiment's controllers — who also monitored them via TV cameras — and an internal e-mail system. Communications with the outside world had 20-minute delays to imitate a real space flight.

Hollywood studios and television networks lost their bid Monday for the Supreme Court to block the use of a new digital video recorder system that could make it cheaper and easier for viewers to record shows and watch them when they want, without commercials.
drunken_boxer777 (985820) writes "In a book to be published next week and in a recent speech in London, James Watson (who shared the 1962 Nobel Prize for medicine for the discovery of the structure of DNA) expressed the idea that blacks do not share "equal powers of reason" with whites:
"There is no firm reason to anticipate that the intellectual capacities of peoples geographically separated in their evolution should prove to have evolved identically. Our wanting to reserve equal powers of reason as some universal heritage of humanity will not be enough to make it so."
From the article:
[H]e said Western policies towards African countries were wrongly based on an assumption that black people were as clever as their white counterparts when "testing" suggested the contrary. He claimed genes responsible for creating differences in human intelligence could be found within a decade.
Having known people with firsthand experience of Dr. Watson's 'conduct', it will be interesting to see whether this incident will be enough to warrant his resignation from Cold Spring Harbor." Link to Original Source
