Cell Phone Interception At Def Con 95

ChrisPaget writes "I'm planning a pretty significant demonstration of GSM insecurity at Defcon next week, where I'll intercept and record cellular calls made by my attendees, live on-stage, no user-input required. As you can imagine, intercepting cellphones is a Very Big Deal in the eyes of the law; this blog post is an attempt to reassure everyone that their privacy is being taken seriously despite the nature of the demo. I'm not just making it up either — the EFF have helped significantly with the details."

Scientists Create Equation For a Perfect Handshake 144

Hugh Pickens writes "Discover Magazine reports that despite the average person shaking hands nearly 15,000 times in a lifetime, one in five (19 per cent) admit they hate the act of the handshake and are unsure how to do it properly, regularly making a handshake faux pas such as having sweaty palms, squeezing too hard or holding on too long while over half the population (56 per cent) say they have been on the receiving end of an unpleasant handshake experience in the past month alone. But help is at hand as scientists have developed a mathematical equation for the perfect handshake taking into account the twelve primary measures needed to convey respect and trust to the recipient. The research was performed at the behest of Chevrolet as part of a handshake training guide for its staff and is meant to offer peace of mind and reassurance to its customers. A full guide to the perfect handshake is available on Flickr."

Why You Never Ask the Designers For a Favor 238

Usually there is nothing funny about a missing pet, but the tale of Missy the lost cat is hilarious. It serves as an example of just how clueless your fellow employees can be, and why you should never ask the designers to drop what they're doing, and help with a personal matter.

First Halophile Potatoes Harvested 117

Razgorov Prikazka writes "A Dutch-based company from Groningen is trying to create a potato race that is able to survive in a saline environment. The first test-batch was just harvested (English translation of Dutch original) on the island Texel and seem to be in good shape. The company states that rising sea-levels will create a demand for halophile crops. I do wonder if one still has to put salt on ones potatoes when they are grown in salt water."

Germany To Test Actively-Cooled Spacecraft 127

FleaPlus writes "The German Aerospace Center is planning to launch a novel reusable spacecraft in 2011, incorporating flat, damage-resistant tiles. Nitrogen will be pumped through the porous tiles, creating a protective gas layer that actively cools and shields the hottest parts of the spacecraft from the searing heat of reentry. The €12.5M unmanned 'SHEFEX II' project is a major technological step toward the team's eventual goal of a reusable space glider, which will be cheaper and easier to build than NASA's space shuttle."

Education Official Says Bad Teachers Can Be Good For Students 279

Zenna Atkins, the chairman of the Office for Standards in Education (Ofsted), has raised some eyebrows by saying that, "every school should have a useless teacher." She stresses that schools shouldn't seek out or tolerate bad teaching, but thinks bad teachers provide a valuable life-lesson. From the article: "... on Sunday Ms Atkins told the BBC that schools needed to reflect society, especially at primary level. 'In society there are people you don't like, there are people who are incompetent and there are often people above you in authority who you think are incompetent, and learning that ability to deal with that and, actually surviving that environment can be an advantage.'"

Mobile Medical Lab — the $10 Phone Microscope 54

kkleiner writes "Aydogan Ozcan of UCLA has developed a microscope attachment for a cell phone – turning the device into a sort of mobile medical lab. It's both lightweight (~38g or 1.5 oz) and cheap (parts cost around $10). The cellphone microscope can analyze blood and saliva samples for microparticles, red blood cells, white blood cells, platelets, and water borne parasites. Ozcan and his team have recently won three prestigious awards for the device: a Grand Challenges award from the Bill and Melinda Gates Foundation (worth $100,000), the National Geographic Emerging Explorer award (worth $10,000), and the CAREER award from the National Science Foundation ($400,000). With these funds, Ozcan plans on starting case studies in Africa to see how the microscope can help revolutionize global medicine."

Survey Says To UK — Repeal Laws of Thermodynamics 208

mostxlnt writes "As we noted, the new Tory UK government has launched a website asking its subjects which laws they'd most like repealed. There are proposals up for repeal of the Laws of Thermodynamics: Second, Third, and all (discussion thread on this one closed by a moderator). One comment on the Third [now apparently deleted] elucidated: 'Without the Third Law of Thermodynamics, it would be possible to build machines that would last forever and provide an endless source of cheap energy. thus solving both potential crises in energy supply as well as solving the greenhouse gas problem in one step... simples... eh?'"

UK Gov't Launches 'Your Freedom' Website To Seek Laws Worth Repealing 332

Firefalcon writes "The UK Government launched Thursday the 'Your Freedom' website, headed by the Deputy Prime Minister Nick Clegg, to 'identify laws that should be repealed.' In a recent tweet, Police State UK pointed out an article in the New Statesman which appeals for people to call on the Government to repeal the ill thought-out Digital Economy Act that was rushed through Parliament without sufficient scrutiny. While part of the Act is regarding the digital TV switchover, other sections allow for users to be restricted or disconnected from the Internet at the behest of copyright owners, which goes against the principle of 'innocent until proven guilty' that has been in place since the Magna Carta."

Boy Builds Wall-Climbing Machine Using Recycled Vacuums 96

Joe McIntosh writes "Hibiki Kono just might be a boy genius. The 13-year-old decided he wanted to climb vertical surfaces like his hero, Spiderman. So, he used two 1,400-watt recycled vacuum cleaners and a little bit of elbow grease to make a machine that allows him to scale walls. Kono has been scaling the walls of his UK school and has told the media that he hopes his invention will help window washers eliminate clumsy ladders from their daily routine."

Solar-Powered Flight Grounded By Equipment Bug 28

crimeandpunishment writes "If your plane is powered by the sun, it's tough to fly if your crew is in the dark. A 24-hour test flight for the world's first solar-powered round-the-world flight had to be postponed Thursday due to an equipment problem that would have left mission control out of touch with the technology on the experimental aircraft. When they're able to make this test flight, they hope by flying all day they'll be able to fully charge the batteries, then use the stored energy to power the plane all night."

Tracking Down a Single-Bit RAM Error 277

Hanji writes "We have discussed here before the potential effects of and protections against cosmic ray radiation, but for the average computer user, it's an obscure threat that doesn't affect them in any real way. Well, here's a blog post that describes a strange segfault and, after extensive debugging, traces it down to a single bit flip, probably caused by a stray cosmic ray. Lots of helpful descriptions of Linux debugging techniques in this one, and a pretty clear demonstration that this can be a real problem. I know I'm never buying a desktop without ECC RAM ever again!" The author acknowledges that it might not have been a cosmic ray-based error, but the troubleshooting steps are interesting no matter what the cause.

Building a Homemade Nuclear Reactor In NYC 219

yukk writes "Mark Suppes, a web developer for Gucci, is working on his own personal fusion reactor. His work in a NYC warehouse using $35,000 of his own money and $4,000 raised on a website has made him the 38th independent researcher recognized as creating a working fusion reactor. How's that for a hobby?"

Yikes! That is ONE TOUGH PROJECT. Sure am glad I'm not working on it! *sigh of relief*
