UK Students Build Electric Car With 248-Mile Range 192

da_how writes "A group of students and graduates at Imperial College London have built an electric car with a massive range — 248+ miles on a charge at 'reasonable' highway speeds (60 mph). They did this by filling the car to the absolute max with as many lithium iron phosphate batteries as possible — 56 kWh — and designing a very efficient direct drive powertrain, about 90% batteries-to-wheels at highway speeds. The choice of vehicle is an interesting one: it's a converted Radical SR8 — a track racing car with a speed record on the Nurburgring. Not an obvious contender for an endurance vehicle (no windscreen either!) — but then they claim it's lightweight to start with, being constructed of steel space frame and glass fiber. Also, Radical is based in the UK and provided some help and sponsorship. The students plan to drive their 'SRZero' 15,000 miles down the Pan American Highway, beginning July 8 in Prudhoe Bay, Alaska, and ending up in Tierra Del Fuego three month later. That's about 60 charges."

Scientists Question Safety of New Airport Scanners 357

An anonymous reader sends this quote from a story at NPR about the accelerated deployment of new scanning machines at airports: "Fifty-two of these state-of-the-art machines are already scanning passengers at 23 US airports. By the end of 2011, there will be 1,000 machines and two out of every three passengers will be asked to step into one of the new machines for a six-second head-to-toe scan before boarding. About half of these machines will be so-called X-ray back-scatter scanners. They use low-energy X-rays to peer beneath passengers' clothing. That has some scientists worried. ... The San Francisco group thinks both the machine's manufacturer, Rapiscan, and government officials have miscalculated the dose that the X-ray scanners deliver to the skin — where nearly all the radiation is concentrated. The stated dose — about .02 microsieverts, a medical unit of radiation — is averaged over the whole body, members of the UCSF group said in interviews. But they maintain that if the dose is calculated as what gets deposited in the skin, the number would be higher, though how much higher is unclear."

Doctors Seeing a Rise In "Google-itis" 368

It's one of the fastest-growing health issues that doctors now face: "Google-itis." Everyone from concerned mothers to businessmen on their lunch break are typing in symptoms and coming up with rare diseases or just plain wrong information. Many doctors are bringing computers into examination rooms now so they can search along with patients to alleviate their fears. "I'm not looking for a relationship where the patient accepts my word as the gospel truth," says Dr. James Valek. "I just feel the Internet brings so much misinformation to the (exam) room that we have to fight through all that before we can get to the problem at hand."

Programming Clojure 109

eldavojohn writes "Programming Clojure by Stuart Halloway was very near to the perfect book for me. It covers many things common to many Lisp languages while highlighting in moderate detail the things that make Clojure unique and worthy of some attention. The book spends a large amount of time dealing with the intricacies of interfacing fluidly with Java (down to a package rewrite inside a large project). This fits me perfectly as a Java programmer, and I now feel ready to experiment with peppering functional language capabilities into an object oriented language. The book also strives to show how to simplify multithreading through functional programming, which is good because I find multithreading in Java a serious headache that few are good at. Programming Clojure, released in May 2009, is currently the only book out there devoted to Clojure, and the introduction is written by the language's creator, Rich Hickey, who says, 'What is so thrilling about Stuart's book is the extent to which he "gets" Clojure.' The book earns its place on the Pragmatic Bookshelf by guiding the user through rewriting a part of Ant into a new build tool called Lancet — adding to the project what you just learned about Clojure at the end of each chapter." Keep reading for the rest of eldavojohn's review.

ACLU Sues To Protect Your Right To Swear 698

The ACLU is suing the police in Pennsylvania for issuing tickets to people who swear. They argue that it is every American's constitutional right to drop an F-bomb. From the article: "'Unfortunately, many police departments in the commonwealth do not seem to be getting the message that swearing is not a crime,' said Marieke Tuthill of the ACLU of Pennsylvania. 'The courts have repeatedly found that profanity, unlike obscenity, is protected speech.'" This is a big f*cking deal.

California Moves To Block Texas' Textbook Changes 857

eldavojohn writes "Yesterday the Texas textbook controversy was reported internationally but the news today heats up the debate as California, a state on the other side of the political spectrum, introduces legislation that would block these textbook changes inside California. Democrat Senator Leland Yee (you may know him as a senator often tackling ESRB ratings on video games) introduced SB1451, which would require California's school board to review books for any of Texas' changes and block the material if any such are found. The bill's text alleges that said changes would be 'a sharp departure from widely accepted historical teachings' and 'a threat to the apolitical nature of public school governance and academic content standards in California.'"

Using Augmented Reality To Treat Cockroach Phobia 126

RichDiesal writes "In this blog post, I describe a new use for augmented reality — treating people for cockroach phobia. A recent paper in the academic journal Cyberpsychology, Behavior and Social Networking discusses a system where people suffering from cockroach phobia sit at a desk with a virtual reality headset. The headset has a camera on the front so that patients see the desk they're sitting at — but covered in cockroaches. In the study, researchers managed to elicit a fear response to virtual cockroaches similar to what would be experienced with real cockroaches. Sounds like a little slice of hell to me."

Complex Life Found Under 600 Feet of Antarctic Ice 237

Chroniton writes "NASA ice scientists have found a shrimp-like creature and a possible jellyfish 'frolicking' beneath 600 feet of solid Antarctic ice, where only microbes were expected to live. The odds of finding two complex lifeforms after drilling only an 8-inch-wide hole suggests there may be much more. And if such life is possible beneath Earth's oceans, why not elsewhere, like Europa?"
