The Prospects For Lunar Mining 348

MarkWhittington writes "With the discovery of vast amounts of water on the Moon, some frozen in the shadows of craters at the Lunar poles and some chemically bonded with the regolith, interest in lunar mining has arisen among commercial space entrepreneurs. Paul Spudis, a lunar geologist, has suggested a plan to return to the Moon, which features, among other things, robotic resource extraction and the deployment of space-based fuel depots using lunar water even before the first human explorers return to the lunar surface. But Mike Wall, writing in Space.com, suggests that there are a number of legal as well as technical issues involved in setting up lunar mining operations."

Extinct Mammoth, Coming To a Zoo Near You 312

Techmeology writes "Professor Akira Iritani of Kyoto University plans to use recent developments in cloning technology to give life to the currently extinct woolly mammoth. Although earlier efforts in the 1990s were unsuccessful due to damage caused by extreme cold, Professor Iritani believes he can use a technique pioneered by Dr Wakayama (who successfully cloned a frozen mouse) to overcome this obstacle. This technique will enable Professor Iritani to identify viable cell nuclei, and transfer them to egg cells of an African elephant which will carry the mammoth for a 600 day pregnancy."

Congresswoman and Staff Gunned Down 2166

tkprit writes "What a shame that a Congresswoman makes herself available to her constituents and she and six of her staff were gunned down for the effort. Rep. Gabrielle Giffords of Arizona was shot, along with members of her staff, for trying to hear the concerns of the people she represents." CNN reports that at least 12 people were shot by the gunman. According to NPR, "The suspect ran off and was tackled by a bystander. He was taken into custody. Witnesses described him as in his late teens or early 20s." Update: 01/08 20:07 GMT by S : Other sources are reporting she's still in surgery, and early reports have been amended to list Congresswoman Giffords in critical condition.

Hackers Find New Way To Cheat On Wall Street 271

GMGruman writes "The high-speed trading exchanges that conduct the business of buying and selling stocks and mutual funds are so fast that hackers can introduce delays of a few microseconds completely unnoticed by today's network monitoring technology — and manipulate prices in the process to reap millions of dollars to the detriment of everyone else, InfoWorld's Bill Snyder reports. This kind of activity creates new reason to distrust Wall Street and shows how the computer networks we all rely on for conducting business and moving information are ripe for undetectable hacking."

SEGA Brings Gaming To Public Restroom Toilets 138

kkleiner writes "SEGA recently announced that they are testing their Toylets male urinal video game at select locations around Tokyo. Toylets uses a pressure sensor located on the back of the urinal to measure the strength and location of your urine stream. A small LCD screen above the urinal allows you to play several simple video games including a simulator for erasing graffiti and a variation on a sumo wrestling match. At the end of a game, the screen displays advertisements. Whether you find the concept hilarious, disturbing, or disgusting, urinal video games are simply another way that interactive media could invade every part of our lives. It also shows that no space is safe from digital ads."

Tobacco Virus Could Boost Li Batteries 161

siliconbits alerts us to the possible use of one of the world's most destructive naturally occurring scourges, the tobacco mosaic virus, to boost the capacity of lithium ion batteries by 10 times. It seems the virus can be made to attach itself to the electrodes in a lithium cell perpendicularly, increasing the surface area of the electrode and greatly improving the battery's capacity to store energy. PhysOrg has some more detail on virus-enhanced batteries. Four years ago we discussed the use of the tobacco mosaic virus to enable fast-switching transistors.

Is Twitter Censoring Wikileaks Trends? 191

comforteagle writes "There are suspicions coming to the surface this morning that Twitter may be censoring WikiLeaks-related tweets from forming a trending topic. Why is still unclear at this point, as during Iranian protests a short while ago Twitter appeared to be in the fray of helping to spread the word. As of this morning it appears that Twitter may have some explaining to do. One of Twitter's engineers has chimed in over the weekend, but some aren't convinced."

Spine Implant Helps Paralyzed People Exercise 39

An anonymous reader writes "British engineers have created the first muscle-stimulating microchip small enough that several can be implanted in a person's spinal canal. In addition to providing enough stimulation to, say, let users pedal a stationary bicycle, they could also be used for things like stimulating bladder muscles to help overcome incontinence. Their breakthrough is that the devices package everything into one tiny unit. Lasers cut tiny electrodes from platinum foil, which are then folded into a 3D shape that looks like the pages of a book. These pages, in turn, wrap around the nerve roots."

"The prototype on display has a take-off weight of only 220 grams with a maximum speed of six-to-10 meters a second and an altitude ranging from 20-200 meters. A spokesperson said the micro-UAV would mainly be used for low-altitude reconnaissance for troops in the field." This is not in the linked article...

One Step Closer To Speedier, Bootless Computers 249

CWmike writes "Physicists at the University of California at Riverside have made a breakthrough in developing a 'spin computer,' which would combine logic with nonvolatile memory, bypassing the need for computers to boot up. The advance could also lead to super-fast chips. The new transistor technology, which one lead scientist believes could become a reality in about five years, would reduce power consumption to the point where eventually computers, mobile phones and other electronic devices could remain on all the time. The breakthrough came when scientists at UC Riverside successfully injected a spinning electron into a resistor material called graphene, which is essentially a very thin layer of graphite. The graphene in this case is one-atom thick. The process is known as 'tunneling spin injection.' A lead scientist for the project said the clock speeds of chips made using tunneling spin injection would be 'thousands of times' faster than today's processors. He describes the tech as a totally new concept that 'will essentially give memory some brains.'"

Hubble In Anaglyph Stereo 3D 114

rwllama writes "We at the Hubble Space Telescope have quietly released our first anaglyph (i.e. red/cyan) stereo 3D movie of a flight into a Hubble image. This work is a follow-on to the sequences we produced for the 'Hubble 3D' Imax film. Note that the 3D interpretation uses lots of artistic license, so it is not intended to be scientifically accurate. We would love to hear the Slashdot crowd's feedback on whether you want more, are artistic interpretations of scientific data acceptable, is anaglyph 3D too annoying, how many could watch this with a real 3D (e.g., NVIDIA 3D Vision) setup, etc?"

Tractor Beams Come To Life 127

Jamie is helping bring our childhood fantasies/nightmares to life with a link that says "Andrei Rhode, a researcher involved with the project, said that existing optical tweezers are able to move particles the size of a bacterium a few millimeters in a liquid. Their new technique can move objects one hundred times that size over a distance of a meter or more."

Market Data Firm Spots the Tracks of Bizarre Robot Trading 483

jamie spotted a fascinating story at The Atlantic about "mysterious and possibly nefarious trading algorithms [that] are operating every minute of every day in" the stock market: "Unknown entities for unknown reasons are sending thousands of orders a second through the electronic stock exchanges with no intent to actually trade. Often, the buy or sell prices that they are offering are so far from the market price that there's no way they'd ever be part of a trade. The bots sketch out odd patterns with their orders, leaving patterns in the data that are largely invisible to market participants." Spotting the behavior of these bots was possible by looking at much finer time slices than casual traders ever see — cool detective work, but as the story points out, discovering it is just the beginning: "[W]e're witnessing a market phenomenon that is not easily explained. And it's really bizarre."

Toyota Robot Violinist Wows At Shanghai Expo 121

kkleiner writes "The Shanghai World Expo got a special treat this past week in the Japanese pavilion, when Toyota's famed violin-playing robot thrilled the crowd with a rendition of the Chinese folk song Mo Li Hua (jasmine flower). The bipedal artificial violinist hasn't been seen much since its debut back in 2007. Now we have footage of the Toyota bot playing Mo Li Hua in Shanghai as well as its original rendition of Pomp and Circumstance from 2007."
