heychris writes"You've gotta love the Chicago Tribune's story on Tesla Coil hobbyists from the first sentence. 'Under a starry Saturday sky behind a Lake Zurich warehouse, three men unload a small flamethrower, electric cabling, neon-tube "light sabers," about 80 pounds of chain mail and two 7-foot devices that look like monster-movie props.' So what does one do with 1.6 million (sorry, not 1.21 jigga-) watts and a Tesla coil or two? Play 110dB music, of course."

Cool-Tether Links Phones' Bandwidth To Make High-Speed Hotspots

Barence writes "Microsoft Research has found a novel way of beating the deplorably slow speeds of mobile broadband, by combining several phones together to make one high-speed hotspot. Dubbed Cool-Tether, the system harnesses the mobile data connection of multiple mobile handsets to build an on-the-fly Wi-Fi hotspot. 'To address the challenges of energy efficiency, Cool-Tether carefully optimises the energy drain of the WAN (GPRS/EDGE/3G) and Wi-Fi radios on smartphones,' Microsoft's research paper claims. 'We prototype Cool-Tether on smartphones and, experimentally, demonstrate savings in energy consumption between 38%-71% compared to prior energy-agnostic solutions.'"

DIY cat feeder now enabled by a Cisco switch, streams food and video

By Richard Lai posted Nov 30th 2009 11:58PM


You know, there are times when you have to part ways with your adorable kitties at home, and you might not be so keen on getting a cat sitter in case he or she touches your precious game consoles (even if it's an old granny). We've seen the lazy man's solution before, but Britain's Mathew Newton has brought us a new DIY internet-enabled cat feeder just in time for a new decade. Rather than using a CD-ROM tray to push-release unknown quantities of cat food, Mathew's version has a motor-driven cereal dispenser controlled by signal from port status LEDs on a Cisco switch -- an ingenious way to avoid expensive Ethernet relay units. When it's feeding time the user logs onto a web interface to choose the dispensing quantity, or you can also have an automatic feed schedule set up if you trust the system -- Mathew said he "can rely on it 100%," and his cats do appear to be healthy. Fortunately, you can always check the live video stream just in case you have doubts. All is explained in the video after the break.

Scientists Create Artificial Meat

Hugh Pickens writes "The Telegraph reports that scientists have created the first artificial meat by extracting cells from the muscle of a live pig and putting them in a broth of other animal products where the cells then multiplied to create muscle tissue. Described as soggy pork, researchers believe that it can be turned into something like steak if they can find a way to 'exercise' the muscle and while no one has yet tasted the artificial meat, researchers believe the breakthrough could lead to sausages and other processed products being made from laboratory meat in as little as five years' time. '"What we have at the moment is rather like wasted muscle tissue. We need to find ways of improving it by training it and stretching it, but we will get there," says Mark Post, professor of physiology at Eindhoven University. "You could take the meat from one animal and create the volume of meat previously provided by a million animals." Animal rights group Peta has welcomed the laboratory-grown meat, announcing that "as far as we're concerned, if meat is no longer a piece of a dead animal there's no ethical objection while the Vegetarian Society remained skeptical. "The big question is how could you guarantee you were eating artificial flesh rather than flesh from an animal that had been slaughtered. It would be very difficult to label and identify in a way that people would trust.""

In Motor Learning, New Brain Connections Form Rapidly

Posted by kdawson on Monday November 30, @04:48AM
from the reaching-out dept.
Science Daily has a report on research demonstrating directly that new connections begin to form between brain cells almost immediately as animals learn a new task. A team lead by researchers at UC Santa Cruz performed"...detailed observations of the rewiring processes that take place in the brain during motor learning. The researchers studied mice as they were trained to reach through a slot to get a seed. They observed rapid growth of... synapses between nerve cells in the motor cortex... The study used mice that had been genetically altered to make a fluorescent protein within certain neurons in the brain. The researchers were then able to use a special microscopy technique (two-photon microscopy) to obtain clear images of those neurons near the surface of the brain. The noninvasive imaging technique enabled them to view changes in individual brain cells of the mice before, during, and after the mice were trained in the seed-reaching task."

Air Cannon Ties Pirates In Knots

from the in-ur-seas-twistin-ur-propeller dept.
Hugh Pickens writes"Numerous high-tech devices have been proposed to help ships cope with piracy on the high seas. Now a company has developed a ship-borne launching device that fires a net or coiled rope into the path of pirate vessels using compressed air with a range of up to a range of 400m. The payload net or rope, which has a parachute attached to the end, will unravel and lay out across the surface of the water so that as the pirate boat travels through the water its propeller shaft will pick up the line and become entangled. 'With the trials and testing we've done,it has taken us some 45 minutes to cut and disentangle the line from the propeller itself,' says Jonathan Delf. 'Within that time of course, the target ship is on its way and hopefully help has arrived in the form of naval forces or helicopter support.' The system can be fired up to five times off just a cylinder of air like a simple scuba tank."The video mentions that the device can also fire a payload of golf balls. The systems have recently be sold to "several large shipping companies that travel near the oil-rich Nigerian Delta, which, like the Somalian coast, is rife with piracy."

In addition to hiding out as a roadie with indy band 'The Hermit Thrushes' for a week, Ratliff donned a variety ofincreasingly impressive disguises. It's an interesting read on how to disappear in the digital age: 'August 13, 6:40 PM: I'm driving East out of San Francisco on I-80, fleeing my life under the cover of dusk. Having come to the interstate by a circuitous route, full of quick turns and double backs, I'm reasonably sure that no one is following me. I keep checking the rearview mirror anyway. From this point on, there's no such thing as sure. Being too sure will get me caught. About 25 minutes later, as the California Department of Transportation database will record, my green 1999 Honda Civic, California plates 4MUN509, passes through the tollbooth on the far side of the Carquinez Bridge, setting off the FasTrak toll device, and continues east toward Lake Tahoe. What the digital trail will not reflect is that a few miles past the bridge I pull off the road, detach the FasTrak, and stuff it into the duffle bag in my trunk, where its signal can't be detected. There will be no digital record that at 4 AM I hit Primm, Nevada, a sad little gambling town about 40 minutes from Vegas, where $15 cash gets me a room with a view of a gravel pile...' Spoiler alert: We previously discussed the denouement of the contest."

Is Global Warming Unstoppable?

ScienceDaily (Nov. 24, 2009) — In a provocative new study, a University of Utah scientist argues that rising carbon dioxide emissions -- the major cause of global warming -- cannot be stabilized unless the world's economy collapses or society builds the equivalent of one new nuclear power plant each day.

Bring your laptop when you travel

This is a comment from slashdot.

Take your laptop, the freedom to transfer your photos locally, and ready internet access with wifi will make it worthwhile. There are internet cafes around, but it'll be more fuss to find one and time out of your vacation, rather than just packing a power convertor and changing your wifi settings.

Other things you might want to do in London could include:

Of course, there are many other things too as people will list below, London is a big place with lots to see and do, enjoy your trip!

Skin Color Gives Clues to Health

ScienceDaily (Nov. 23, 2009) — Researchers from the universities of Bristol and St. Andrews in the UK have found that the color of a person's skin affects how healthy and therefore attractive they appear, and have found that diet may be crucial to achieving the most desirable complexion. The work will be published in the December issue of Springer's International Journal of Primatology.

pdclarry writes"A recent study by scientists at the American Museum of Natural History and Columbia University found that a piece of tuna sushi may not be tuna at all: 'A piece of tuna sushi has the potential to be an endangered species, a fraud or a health hazard,' wrote the authors. 'All three of these cases were uncovered in this study.' The study, published in PLoS ONE examined 68 samples of tuna sushi purchased from 31 restaurants in Manhattan (New York City) and Denver, Colorado. Some of these were from endangered species, others were not as labeled, and some were not tuna at all. Of these last, five samples labeled as 'white tuna' were from a toxic fish, Escolar, which is a gempylid species banned for sale in Italy and Japan due to health concerns. 'It can cause gastrointestinal symptoms ranging from mild and rapid passage of oily yellow or orange droplets, to severe diarrhea with nausea and vomiting. The milder symptoms have been referred to as keriorrhea [i.e. flow of wax in Greek].' Fraud in sushi is not new; Slashdot also reported study on mislabeling in 2008. This new study shows that some sushi can actually make you sick. The study was also covered by Wired."

Presto Vivace writes"Brian Krebs of the Washington Post reports on a study jointly released Tuesday by the Ontario Information and Privacy Commissioner and the Future of Privacy Forum. It seems that in the process of collecting all that feedback about energy use, utility companies will inevitably collect a great deal of information about us. From the article: 'Instead of measuring energy use at the end of each billing period, smart meters will provide this information at much shorter intervals, the report notes. Even if electricity use is not recorded minute by minute, or at the appliance level, information may be gleaned from ongoing monitoring of electricity consumption such as the approximate number of occupants, when they are present, as well as when they are awake or asleep. For many, this will resonate as a "sanctity of the home" issue, where such intimate details of daily life should not be accessible.'"

Youths See All Parental Control Negatively When There's A Lot Of It

ScienceDaily (Nov. 13, 2009) — A new study has found that young people feel differently about two types of parental control, generally viewing a type of control that's thought to be better for their development more positively. However, when parents are very controlling, young people no longer make this distinction and view both types of parental control negatively.

Great White Sharks Visiting San Francisco

Ponca City, We love you writes"Juliet Eilperin writes in the Washington Post that while for years, humans have thought of great white sharks as wandering the sea at random, only occasionally venturing close to shore, it turns out we were wrong. Scientists lured 179 great white sharks to their boat with a carpet decoy designed to look like a seal, and used a lance to attach satellite tags with the aid of 2.3-inch titanium darts to track the sharks and discovered that Pacific white sharks spend months near the northern and central California coast between August and February, foraging among elephant seals, sea lions, and other prey. The sharks were spotted as far inland as the mouth of the San Francisco Bay, east of the Golden Gate Bridge. 'It shows you how wild it is off our West Coast of North America. This is Yellowstone,' says Stanford University marine sciences professor Barbara A. Block. The fact that 'a major concentration' of great whites can ignore humans 'shows us the sharks are really minding their own business. The number of interactions with people is very small, considering,' says Salvador J. Jorgensen."

Ferrari-styled OutRun arcade machine set for crazy scooter transformation? (video)
If you're a child of the '80s and a gamer to boot you surely remember OutRun, the game that rocked a generation with only some parallax effects and pixelated blonde hair -- though the giant arcade cabinet with gold wheels certainly didn't hurt. Now "contemporary artist" Garnet Hertz (creator of the twitching, crunchy frog server) is proposing to give that very cabinet a new lease on life, and a motorized one at that. Hertz wants to take an arcade machine and merge it with an EVT America Electric Trike, making those stylized five-spoke rims actually move. But that's only half of it. He plans to power the display with an iPhone 3GS and use it to render a sort of halcyon 16-bit view of the world ahead, with every road a 64-color dream lined with palm trees. A recent video showing off some of the tech is embedded below, and while we think this is about as likely to turn a wheel as aTeenage Mutant Ninja Turtles cabinet is to travel in time, we'll certainly be first in line with four quarters if it ever does.
