Submission + - Stem Cell Research Inaccurate
MattSparkes writes: "One of the best-known stem cell papers describes adult cells that seemed to hold the same promise as embryonic stem cells. Now some of the data contained within the paper is being questioned, after staff at a consumer science magazine noticed errors. It shows how even peer-reviewed papers can sometimes 'slip through the net' and get to publication even with inaccurate data."
Submission + - Wikipedia is failing
An anonymous reader writes: A growing number of people are concerned about where Wikipedia is heading. Some have left Wikipedia for Citizendium, while others are trying to change the culture of Wikipedia from within. A recent essay called Wikipedia is failing points out many of the problems which must be solved with Wikipedia for it to succeed in its aim of becoming a reputable, reliable reference work. How would you go about solving these problems?
Submission + - Harvard Physicists Bring Light to a Complete Halt
tetrikphimvin writes: "In a quantum mechanical sleight of hand, Harvard physicists have shown that they can not only bring a pulse of light, the fleetest of nature's particles, to a complete halt, but also resuscitate the light at a different location and let it continue on its way.
"It's been a wonderful problem to try to wrap your brain around," said Lene Vestergaard Hau, a professor of physics at Harvard and senior author of a paper describing the experiment that appears today in the journal Nature. "There are so many doors that open up." This is also noted in Harvard's Gazette here, which includes video links."

Submission + - Quantum Computer to launch next week
judgecorp writes: "D-Wave Systems of British Columbia is all set to demonstrate a quantum computer. Simple devices have been built in the lab before, and this is still a prototype, but it is a commercial project which aims to get quantum devices into computer rooms, solving tricky problems — and cracking all our codes. Most quantum computers have to be isolated from the outside world (look at them and they stop working). This one is an "adiabatic" quantum computer — which means (in theory, says D-Wave) it can live with thermal noise and give results without having to be isolated. There's a description of it here — and pretty pictures too."
Google Apps to Become Paid Service 273
FredDC writes "Business Week reports Google Apps is becoming a paid service soon for companies who wish to use it for their domain. Disney and Pixar are reportedly thinking about switching to Google Apps instead of using Microsoft Office. Could this be the end of a monopoly? Or the start of a new one?"
One Laptop Per Child Security Spec Released 253
juwiley writes "The One Laptop Per Child project has released information about its advanced security platform called Bitfrost. Could children with a $100 laptop end up with a better security infrastructure than executives using $5000 laptops powered by Vista? 'What's deeply troubling — almost unbelievable — about [Unix style permissions] is that they've remained virtually the only real control mechanism that a user has over her personal documents today...In 1971, this might have been acceptable...We have set out to create a system that is both drastically more secure and provides drastically more usable security than any mainstream system currently on the market.'"
