Sink Your Balls Quickly With Pool-Cue Robots 79

AndreV writes "In another attempt to dehumanize our bar games, a Canadian engineer has turned the classic game of billiards on its head with his BilliardBots pet project, which consists of a series of remote-controlled mobile robots meant to replace the standard cue sticks normally used to pocket pool balls. While in his version the basic rules remain, unlike regular billiards, players in this version simultaneously rush to pocket their designated balls (they don't take turns), 'thus it's very competitive and fast,' the creator says. In order to keep tight reins on the mechatronic ball handlers' movements, he adapted a pair of Playstation controllers and says that playing 'requires dexterity, like a video game,' to control their 3.5-m/sec-maximum speeds. The 'bots are designed simply but effectively, using a 3-by-3-by-3-inch metal frame with an electronic board, two motors and rechargeable battery packs. Using a Bluetooth wireless communication protocol, its commands come from the wireless controller with single or double joystick selectable control (the other buttons are not used). Its other parameters are software programmable, such as maximum acceleration rate, maximum speed and maximum rotation speed."

DIY Space Photography Screenshot-sm 106

Four Spanish teenagers sent a camera-operated weather balloon into the stratosphere. The boys built the electronic sensor components from scratch. Gerard Marull Paretas, Sergi Saballs Vila, Marta Gasull Morcillo and Jaume Puigmiquel Casamort attached a £56 camera to a heavy duty £43 latex balloon, and sent their science project 20-miles above the Earth. Team leader Gerard Marull, 18, said, "We were overwhelmed at our results, especially the photographs, to send our handmade craft to the edge of space is incredible."

Intel Develops Micro-Refrigerator To Cool Chips 94

Spacedonkey writes "Researchers at Intel, RTI International of North Carolina, and Arizona State University have made ultra-thin 'micro-refrigerators' for computer chips. The device uses a thermoelectric cooler made from nanostructured thin-film superlattice that can reduce the temperature by 55C when a current passes through it. In testing, it reduced the temperature on part of a chip by 15C without impairing its performance. The researchers say the component could be particularly useful for cooling hot spots that frequently occur on multi-core chips."

South Carolina Seeking To Outlaw Profanity Screenshot-sm 849

MBGMorden writes "It looks like in an act that defies common sense, a bill has been introduced in the South Carolina State Senate that seeks to outlaw the use of profanity. According to the bill it would become a felony (punishable by a fine up to $5000 or up to 5 years in prison) to 'publish orally or in writing, exhibit, or otherwise make available material containing words, language, or actions of a profane, vulgar, lewd, lascivious, or indecent nature.' I'm not sure if 'in writing' could be applied to the internet, but in any event this is scary stuff."

Future Astronauts May Survive On Eating Silkworms 384

sciencehabit writes "Science reports that silkworms may be an ideal food source for future space missions. They breed quickly, require little space and water, and generate smaller amounts of excrement than poultry or fish. They also contain twice as many essential amino acids as pork does and four times as much as eggs and milk. Even the insect's inedible silk, which makes up 50% of the weight of the dry cocoon, could provide nutrients: The material can be rendered edible through chemical processing and can be mixed with fruit juice, sugar, and food coloring to produce jam."

Study Confirms That Cars Have Personalities 213

Ponca City, We love you writes "A study has confirmed that many people see human facial features in the front ends of automobiles and ascribe various personality traits to cars. Forty study participants assessed cars based on a system known as geometric morphometrics by viewing high-resolution, 3D computer reconstructions and printed images of 38 actual 2004-06 car models and rating each model on 19 traits such as dominance, maturity, gender, and friendliness, and if they liked the car. Study participants liked best the cars scoring high in the so-called power traits — the most mature, masculine, arrogant, and angry-looking ones. Researchers theorized that over evolutionary time, humans have developed a selective sensitivity to features in the human face that convey information on sex, age, emotions, and intentions. The lead researcher explained, 'Seeing too many faces, even in mountains or toast, has little or no penalty, but missing or misinterpreting the face of a predator or attacker could be fatal.'"

Comment Guilty until proven innocent? (Score 1) 426

"...names were entered into the state police database as terrorists partly because the software offered limited options for classifying entries."

So much for guilty until proven innocent. If the correct classification doesn't exist, then don't enter in the name until one does. You wouldn't put their names in as murderers or child pornographers. They are not terrorists, don't call them such.

Rat-Brained Robots Take Their First Steps 289

missb writes "Brain tissue cultured from rats has controlled a wheeled robot around a lab, according to New Scientist this week. Researchers in the UK have harnessed signals from thousands of disembodied rat neurons, and manipulated them to get a robot to respond to instructions. The team at the University of Reading in the UK hope their research will help provide treatments for diseases like Alzheimer's and epilepsy."

Mercedes To Phase Out Gasoline By 2015 908

arbitraryaardvark sends in a story a couple of weeks back in Yahoo's Ecogeek blog, reporting that Mercedes will phase out petroleum-powered cars by 2015 (mirror), and notes: "Story is unconfirmed but well sourced." "In less than 7 years, Mercedes-Benz plans to ditch petroleum-powered vehicles from its lineup. Focusing on electric, fuel cell, and biofuels, the company is revving up research in alternative fuel sources and efficiency."
