An anonymous reader writes"European researchers have developed a new approach to artificial intelligence that could allow computers to respond to behavior as well as commands, reacting intelligently to the subtle nuances of human communication. It's no trivial feat – many humans struggle with the challenge on a day-to-day basis."

Electrolux "Silence Amplified" vacuum with iPod dock and speakers probably sucks

By Thomas Ricker posted Dec 10th 2009 6:59AM

Crazy huh? Sure, but if your company just launched a commercial vacuum cleaner so quiet that it's called the "UltraSilencer" then what better way to drive that point home than by adding an "iPod dock" (though that's no iPod we've ever seen) and speakers to the damn thing? In fact, Electrolux has taken this Silence Amplified concept so far that they've conducted a lab study to prove that "music assisted vacuuming increases the number of nozzle sweeps, improves the cleaning result and leaves a general feeling of happiness." Duh. Now go check the video evidence after the break.


Are Holiday and Weekend Eating Patterns Affecting Obesity Rates?

ScienceDaily (Dec. 10, 2009) — The holidays can be challenging for even the most diligent dieters. But are weekends just as detrimental? Researchers at the University of Pittsburgh and Quinnipiac University in Hamden, Conn., found that weekend eating patterns change significantly.

Electromagnetic Fields as Cutting Tools

ScienceDaily (Dec. 10, 2009) — The bodywork on motor vehicles must be sufficiently stable, but processing the high-strength steels involved -- for example punching holes in them -- can prove something of a challenge. A new steel-cutting process will save time, energy and money in the future.

UK man builds life-sized Dalek, furthers intergalactic evil

By Joseph L. Flatley posted Dec 8th 2009 3:54PM

Sci-fi fandom and the DIY ethic go hand in hand -- and for evidence, you need only look at the large number of Star Trek and Star Wars-themed projects we've seen in this space over the years. Still, few of them have achieved the scope of the full-sized Dalek that Rob Bosher built for about £700 (roughly $1,140). Powered by an electric wheelchair and constructed mostly from wood, this guy can be piloted via remote control and even features working lights, a moving eye (a reconstituted magic eight ball) and a voice modulator for the creepy, alien order to "exterminate." When not trying to slowly (very slowly) populate the earth with a robot army bent on universal conquest and destruction, Bosher hopes to use his project to make money for regional charities.

Sea Level Could Rise from 0.75 to 1.9 Meters This Century

ScienceDaily (Dec. 8, 2009) — A new scientific study warns that sea level could rise much faster than previously expected. By the year 2100, global sea level could rise between 75 and 190 centimetres, according to a paper published in the Proceedings of the National Academy of Sciences.

Craving Hinders Comprehension Without You Realizing It

I wonder if this translates to strong food cravings too? My experience says yes.

ScienceDaily (Dec. 8, 2009) — A new University of Pittsburgh study reveals that craving a cigarette while performing a cognitive task not only increases the chances of a person's mind wandering, but also makes that person less likely to notice when his or her mind has wandered.

A Greener Way to Get Electricity from Natural Gas

ScienceDaily (Dec. 8, 2009) — A new type of natural-gas electric power plant proposed by MIT researchers could provide electricity with zero carbon dioxide emissions to the atmosphere, at costs comparable to or less than conventional natural-gas plants, and even to coal-burning plants. But that can only come about if and when a price is set on the emission of carbon dioxide and other greenhouse gases -- a step the U.S. Congress and other governments are considering as a way to halt climate change.

Linux Reaches 32% Netbook Market Share

from the one-third-of-world-domination dept.
christian.einfeldt writes"Linux netbooks have captured 32% of the global netbook market, says Jeff Orr, an analyst with consumer computer research firm ABI Research. The largest share of netbook sales is in the Asia-Pacific region, including Japan, Australia, and New Zealand, according to Orr. ABI's latest figures align with a statement by Dell executives in February of this year, to the effect that Linux netbooks comprised about 33% of Dell shipments of Dell Inspiron mini 9s netbooks. These data points cast doubt on claims by Microsoft that Windows XP has captured 98% of the netbook market (a figure Microsoft later revised to 93%). In an interview with DesktopLinux.com, Orr made clear that the 32% Linux netbook market share did not include either user-installed Linux or dual-boot systems, but was confined to just pre-installed Linux shipments."

Confused school district fires sysadmin for running SETI@home: 'As an educational institution we do not support the search for E.T.'

By Nilay Patel posted Dec 2nd 2009 3:24PM

We've dealt with a number of confused and outright foolish school administrators in our time, but it seems like Arizona's Higley Unified School District might be run by the most bonkers of the bunch: they've fired IT director Brad Niesluchowski for running SETI@Home on some 5,000 of the district's machines. Why? According to confidently-underinformed superintendent Denise Birdwell, Higley Unified "certainly would have supported cancer research," but does "not support the search for E.T." Well, that's just peachy -- except that her flippant dismissal of SETI belies a complete ignorance of one of the oldest and most respected distributed-computing projects in the world, and what it's actually looking for. Oh, but it gets worse: Birdwell thinks SETI@home -- which primarily runs as a screensaver -- was somehow slowing down "educational programs in every classroom," and magically estimates that it's cost her district "$1 million in added utility fees and replacement parts," with a further huge cost required to remove the software. Completing her transformation into the worst-possible stereotype of a school district superintendent, Birdwell's even got the local cops on the case. Yeah, it's idiotic, but it could be worse -- we can only imagine the hell that would have broken loose had Higley's machines been a part of the renegade Engadget Folding@home team.

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."

Shedding Your Identity In the Digital Age

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!

Is That Sushi Hazardous To Your Health?

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."
