Tooth Regeneration Coming Soon
Ponca City, We love you writes "For thousands of years, losing teeth has been a routine part of human aging. Now the Washington Post reports that researchers are close to growing important parts of teeth from stem cells, including creating a living root from scratch, perhaps within one year. According to Pamela Robey of the NIH. 'Dentists say, "Give me a root and I can put a crown on it."' In a few years dentists will treat periodontal disease with regeneration by using stem cells to create hard and soft tissue; they will take out a tooth that is about to fall, and reconnect it firmly to the regenerated tissue. Although nobody is predicting when it will be possible to grow teeth on demand, in adults, to replace missing ones, a common guess is five to ten years. Baby and wisdom teeth are sources of stem cells that could be 'banked' for future health needs, says Robey. 'When you think about it, the teeth children put under their pillows may end up being worth much more than the tooth fairy's going rate. Plus, if you still have your wisdom teeth, it's nice to know you're walking around with your own source of stem cells.'"pa href="http://science.slashdot.org/article.pl?sid=09/01/06/018202amp;from=rss"img src="http://slashdot.org/slashdot-it.pl?from=rssamp;op=imageamp;style=h0amp;sid=09/01/06/018202"/a/ppa href="http://science.slashdot.org/article.pl?sid=09/01/06/018202amp;from=rss"Read more of this story/a at Slashdot./p

Amazon S3 Adds Option To Make Data Accessors Pay
CWmike writes "Amazon.com has rolled out a new option for its Simple Storage Service (S3) that lets data owners shift the cost of accessing their information to users. Until now, individuals or businesses with information stored on S3 had to pay data-transfer costs to Amazon when others made use of the information. Amazon said the new Requester Pays option relieves data providers of that burden, leaving them to pay only the basic storage fees for the cloud computing service. The bigger question with the cloud is, who really pays? Mark Everett Hall argues that IT workers do."pa href="http://tech.slashdot.org/article.pl?sid=09/01/06/0013245amp;from=rss"img src="http://slashdot.org/slashdot-it.pl?from=rssamp;op=imageamp;style=h0amp;sid=09/01/06/0013245"/a/ppa href="http://tech.slashdot.org/article.pl?sid=09/01/06/0013245amp;from=rss"Read more of this story/a at Slashdot./p

Carefully Timed Jerks Could Power Space Elevator
Hugh Pickens writes "BBC has an interesting article on the long-standing issue of how to power the 'climber' that would ascend a space elevator into space. Previous ideas have included delivering microwave or laser power to the climber beamed from the Earth's surface, but now European Space Agency ground station engineer Age-Raymond Riise has demonstrated a device that could provide a "lift into space" for cheaper space missions along a 100,000-km long tether anchored to the Earth. Riise demonstrated sending power mechanically by providing carefully timed jerks of the cable at its base with a broomstick to represent the cable held in tension, an electric sander to provide a rhythmic vibration to the bottom of the stick, and three brushes representing the climber with their bristles pointing downwards allowing the climber assembly to slide upward along the broomstick as it moved slightly downward, but grip it as it moved slightly upward. 'It would be possible to make a suspension system that completely decouples the cabin where the passengers are,' says Riise. 'For them it would be a linear movement with very little disturbance.' Riise says that he has been approached by commercial elevator companies, who are researching new ideas for elevators in superscrapers where the simplicity of the approach makes it attractive when compared to other ideas for powering lifts, such as compressed air."pa href="http://science.slashdot.org/article.pl?sid=09/01/05/230211amp;from=rss"img src="http://slashdot.org/slashdot-it.pl?from=rssamp;op=imageamp;style=h0amp;sid=09/01/05/230211"/a/ppa href="http://science.slashdot.org/article.pl?sid=09/01/05/230211amp;from=rss"Read more of this story/a at Slashdot./p

Employees the Next (Continuing) Big Security Risk?
surely_you_cant_be_serious writes "A nationwide survey finds that most companies consider their systems vulnerable to attack. Historically, crime rates increase during recessions mdash; and some believe that cybercrime may well follow suit, especially given massive layoffs and the dim prospects many laid-off employees face in finding a new job. 'One thing companies can start doing is monitoring their networks on an ongoing basis so that they understand the normal pattern of data flow and usage, Brill said. In many cases, companies may not have the internal capability to do this, but outsourcing options are available. Kroll Ontrack, for instance, will be rolling out a 24/7 monitoring service for its global clients manned from a US location by professionals in early 2009.'"pa href="http://it.slashdot.org/article.pl?sid=09/01/05/2137202amp;from=rss"img src="http://slashdot.org/slashdot-it.pl?from=rssamp;op=imageamp;style=h0amp;sid=09/01/05/2137202"/a/ppa href="http://it.slashdot.org/article.pl?sid=09/01/05/2137202amp;from=rss"Read more of this story/a at Slashdot./p

A Hacker's Audacious Plan To Rule the Underground
An anonymous reader writes "Wired has the inside story of Max Butler, a former white hat hacker who joined the underground following a jail stint for hacking the Pentagon. His most ambitious hack was a hostile takeover of the major underground carding boards where stolen credit card and identity data are bought and sold. The attack made his own site, CardersMarket, the largest crime forum in the world, with 6,000 users. But it also made the feds determined to catch him, since one of the sites he hacked, DarkMarket.ws, was secretly a sting operation run by the FBI."pa href="http://it.slashdot.org/article.pl?sid=09/01/05/2038251amp;from=rss"img src="http://slashdot.org/slashdot-it.pl?from=rssamp;op=imageamp;style=h0amp;sid=09/01/05/2038251"/a/ppa href="http://it.slashdot.org/article.pl?sid=09/01/05/2038251amp;from=rss"Read more of this story/a at Slashdot./p
