A Look Back At Kurzweil's Predictions For 2009
marciot writes "It's interesting to look back at Ray Kurzweil's predictions for 2009 from a decade ago. He was dead on in predicting the ubiquity of portable computers, wireless, the emergency of digital objects, and the rise of privacy concerns. He was a little optimistic in certain areas, predicting the demise of rotating storage and the ubiquity of digital paper a bit earlier than it appears it will actually happen. On the topic of human-computer speech interfaces, though, he seems to be way off." And of course Kurzweil missed 9/11 and the fallout from that. His predictions might have been nearer the mark absent the war on terror.

Milky Way Heavier Than Thought, and Spinning Faster
An anonymous reader writes "The Milky Way is spinning much faster and has 50 per cent more mass than previously believed. This means the Milky Way is equivalent in size to our neighbor Andromeda — instead of being the little sister in the local galaxy group, as had been believed. One implication of this new finding is that we may collide with Andromeda sooner than we had thought, in 2 or 3 billion years instead of 5."

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.'"

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."

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."
