I suppose you've never heard of Cobalt-Thorium G. It has a radioactive half-life of 93 years! We can't allow such a dangerous fuel in our reactors! They might melt down and create a doomsday shroud. A lethal cloud of radioactivity which will encircle the earth for 93 years!

Quantum Cloaking Makes Molecules Invisible 118

KentuckyFC writes "An international team of physicists has applied the ideas of cloaking to the quantum world and worked out how to hide quantum objects such as molecules. In the quantum world, seeing is equivalent to detecting a quantum object. In the case of molecules, that means looking for the terahertz radiation they produce when they vibrate (abstract). By designing a 'quantum corral,' an elliptical nanostructures that absorbs terahertz waves at a precise frequency, the team says it is possible to hide molecules that emit at exactly that frequency. They say their quantum corral would be ideally suited to detecting molecules of specific species while ignoring others. And that may mean a new generation of molecular detectors on the horizon."

NVIDIA Makes First 4GB Graphics Card 292

Frogger writes to tell us NVIDIA has released what they are calling the most powerful graphics card in history. With 4GB of graphics memory and 240 CUDA-programmable parallel cores, this monster sure packs a punch, although, with a $3,500 price tag, it certainly should. Big-spenders can rejoice at a new shiny, and the rest of us can be happy with the inevitable price shift in the more reasonable models.

German Foreign Ministry Migrates Desktops To OSS 147

ruphus13 writes "Here's another example of 'German Engineering' — The Foreign Ministry in Germany is migrating all of its 11,000 desktops to GNU/Linux and other open source applications. According to the article, 'this has drastically reduced maintenance costs in comparison with other ministries. "The Foreign Ministry is running desktops in many far away and some very difficult locations. Yet we spend only one thousand euro per desktop per year. That is far lower than other ministries, that on average spend more than 3000 euro per desktop per year ... Open Source desktops are far cheaper to maintain than proprietary desktop configurations," says Rolf Schuster, a diplomat at the German Embassy in Madrid and the former head of IT at the Foreign Ministry ... "The embassies in Japan and Korea have completely switched over, the embassy in Madrid has been exclusively using GNU/Linux since October last year", Schuster added, calling the migration a success.' The Guardian has additional coverage of the move."

When you're in college, you learn how to pinch pennies. I live about 90 miles from my university, the whole trip going along a northish-southish interstate. About 4 years ago, the state raised the posted speed limit to 70 mph. I used to drive about 75, 80 on this stretch, until it rained heavily one night and I did 60 the whole way. I went up from about 28 miles to the gallon to around 32. When I started going 10 miles under the limit in favorable conditions, I got about 36-37. There is absolutely nothing illegal about going 60 on a 70. I've been doing this in a Honda Del Sol, one of the most diminutive cars on the road. So far I haven't been rear ended. Most drivers, especially truckers, see my rate and react accordingly. As long as I stay in the right lane, I'm not holding anyone up or harming traffic flow. And frankly, if you get pissed off for having to react to my slow moving vehicle, I'll get a rise out of your irritation and keep on doing what I'm doing. Especially if you're driving a huge SUV or a BMW.

Open Source Laser Business Opens In New York 96

ptorrone writes "If you can't stand the idea of a cookie-cutter laptop and you live in New York City, you have a new option: laser-etching. Phil Torrone, an editor at Make magazine, and Limor Fried, a former fellow at the tech-focused art studio Eyebeam R&D, are working together on Adafruit Laser Services, a new, by-appointment-only business in Manhattan that etches custom artwork onto customers' laptops, iPods, cell phones, and other gadgets." The entire business will be open source. From the Adafruit Laser Services site: "We are publishing how to use the high powered laser system, set up, techniques, business practices and templates. You could start your own laser business, we'll even help you."

The Moon's Magnetic Umbrellas 125

eldavojohn writes "When it comes to space exploration, there are things that are good for humans (water) and things that are bad for humans (radiation). In order for exploration of the moon to occur, its lack of a global magnetic shield to block solar radiation must be addressed. Luckily, scientists have discovered that there are highly magnetized areas of the moon's crust that could shield settlements." From the article: "Current evidence suggests that impact-basin ejecta materials [material blasted out by huge asteroid or comet impacts] are the most likely sources of many or all of the magnetic fields ... These ejecta contain microscopic metallic iron particles that are the carriers of the magnetization."

Nintendo Promises 4 Million Shipped Wiis By Year-End 69

Nintendo of America President Reggie Fils-Aime wants to share some good news and some bad news. The good news is that by the end of the year Nintendo expects to ship 4 million consoles. The bad news is, they still expect to sell out. From the article: "Nintendo of America president Reggie Fils-Aime hyped up the console launch, saying, 'Because of demand, we're urging shoppers not to get complacent. The level of demand we're seeing goes beyond the ordinary. Retailers are telling us a significant fraction of customers pre-ordering Wii are nontraditional gamers...' The company expects to ship 6 million Wii units globally by the end of March 2007, on par with Sony's worldwide shipment targets for PS3. Microsoft has sold 6 million Xbox 360 units to date since its launch in late November 2005, and hopes to sell 10 million by the end of the calendar year." So, fewer units than the analysts wanted. Still an impressive number.

Cell Phone Use May Be Bad For Your Sperm 120

imaginaryelf writes, "WebMD reports that researchers have found a link between hours of cell phone use and sperm quality. 'In a study led by researchers from The Cleveland Clinic, men who used their cell phones the most had poorer sperm quality than those who used them the least.' We Slashdotters know that correlation does not equal causation, so further research is needed to understand the link, but just in case, maybe men should cut back on the hours of cell phone use?"

How Practical are 20-inch Laptops? 274

GeneralPacket writes "A 20-inch laptop might sound perfect for a game of Grand Theft Auto on the way to work, or navigating a mammoth spreadsheet. But are they really usable as laptops, or are they just luggable desktops? This week CNET attempted to work on the super-sized 20-inch Dell XPS M2010 laptop while travelling across London on the subway. The resulting video review is hilarious. This is not your typical tech video review — it's actually funny, and, refreshingly, completely advertising-free. The reviewer is in constant fear that anti-terrorism police are about to swarm him. Would you use a 20-incher?"

Zango Under Fire From Adult Webmasters 93

An anonymous reader writes, "Over the past few days, adult webmasters have been accusing adware maker Zango of 'stealing sales' by means of the following method: Computer users with Zango's adware on board will pop open a window containing the affiliate merchant's site they happen to be on at the time, except with Zango's own affiliate code in the window. By doing this, Zango claims credit for the sale and the original, rule-following merchant, the one who referred the user there, loses out. Despite this practice having been around since at least 2004, it seems the adult webmasters are only just realizing this takes place — surprising, considering how deeply connected the worlds of adware and porn are. It seems pornographers pushing adware is acceptable only as long as they aren't the ones getting burnt. Part of me doesn't care, and part of me hopes they carry the financial clout to force Zango to change their current practices."

Miami Court Orders Take Two to Hand Over Bully 349

Jabrwock writes "GamePolitics.com reports that a judge in Miami ruled that Take Two Interactive, makers of the controversial title Bully, must hand over a copy of the soon to be released game to the court within 24 hours. Jack Thompson, the plaintiff, called the ruling a 'huge victory against the violent video game industry', although Take Two can still appeal the order. Thompson filed a lawsuit asking the court to label Bully a 'public nuisance' and restrict its October 17 release in Florida."

Laser TV — the Death of Plasma? 351

spoco2 writes, "As reported in major news outlets yesterday in Australia (The Age, the Herald Sun), a new television technology has been developed which is touted (by the developers) as far and away superior to both plasma and LCD. From The Age: 'With a worldwide launch date scheduled for Christmas 2007, under recognisable brands like Mitsubishi and Samsung, Novalux chief executive Jean-Michel Pelaprat is so bold as to predict the death of plasma. "If you look at any screen today, the color content is roughly about 30-35 per cent of what the eye can see," he said. "But for the very first time with a laser TV we'll be able to see 90 per cent of what the eye can see. All of a sudden what you see is a lifelike image on display."' The developing company, Arasor International, is said to be listing on the Australian stock exchange shortly."

Twin-Screen Vista Laptops 176

An anonymous reader writes ""Asus has shown off a prototype of the first dual-screen laptop, the W5Fe. These laptops, bearing the Intel codename 'Newport' have a standard screen on the inside plus a smaller, additional colour display on the outside of the lid. The second display is capable of showing video, flight departure information, movie show times, alerts, games, movies, images and MP3s, all while the laptop is switched off. According to CNET, the battery requirement for such a screen is minimal — with standard laptop batteries providing hundreds of hours of use."

Will the Next Election Be Hacked? 904

plasmacutter writes to let us know about the new article by Robert F. Kennedy Jr. in Rolling Stone, following up on his "Was the 2004 Election Stolen?" (slashdotted here). Kennedy recounts the sorry history of electronic voting so far in this country — and some of the incidents will be new even to this clued-in crowd. (Had you heard about the CERT advisory on an undocumented backdoor account in a Diebold vote-tabulating database — crediting Black Box Voting?) Kennedy's reporting is bolstered by the accounts of a Diebold insider who has gone on record with his concerns. From the article: 'Chris Hood remembers the day in August 2002 that he began to question what was really going on in Georgia... "It was an unauthorized patch, and they were trying to keep it secret from the state," Hood told me. "We were told not to talk to county personnel about it. I received instructions directly from [president of Diebold election unit Bob] Urosevich...' According to Hood, Diebold employees altered software in some 5,000 machines in DeKalb and Fulton counties, the state's largest Democratic strongholds. The tally in Georgia that November surprised even the most seasoned political observers. (Hint: Republicans won.)
