Gasoline From Thin Air 283

disco_tracy writes "An enzyme found in the roots of soybeans could be the key to cars that run on air. If perfected, the tech could lead to cars partially powered on their own fumes. Even further into the future, vehicles could draw fuel from the air itself. Quoting: 'The new enzyme can only make two and three carbon chains, not the longer strands that make up liquid gasoline. However, Ribbe thinks he can modify the enzyme so it could produce gasoline. ... [Perfecting this process] won't happen anytime soon... "It's very, very difficult," to extract the vanadium nitrogenase, said Ribbe.'

Volkswagen Creates Sewage-Powered Beetle Screenshot-sm 83

Hugh Pickens writes "The Telegraph reports that Volkswagen is giving new meaning to the term 'Dung Beetle' with a prototype able to cover 10,000 miles annually on the waste from 70 households. The Bio-Bug was launched by Wessex Water, which is generating methane from human waste at a sewage treatment works near Bristol. 'Our site has been producing biogas for many years, which we use to generate electricity to power the site and export to the National Grid,' says one company official. 'We decided to power a vehicle on the gas, offering a sustainable alternative to using fossil fuels which we so heavily rely on in the UK.' The Anaerobic Digestion and Biogas Association says the launch of the Bio-Bug proves that biomethane from sewage sludge can be used as fuel. 'This is a very exciting and forward-thinking project demonstrating the myriad benefits of anaerobic digestion (releasing energy from waste). Biomethane cars could be just as important as electric cars.'"

Regenerating Muscle Cells With Newt-Inspired Tech 88

gmp writes "The NY Times and the Wall Street Journal are reporting on a new paper, published in the science journal Cell Stem Cell, where scientists, inspired by the ability of newts and other lower organisms to regrow lost limbs, have demonstrated that adult mammalian cells can be made to regenerate by suppressing a pair of anti-cancer genes. 'Interfering with tumor suppressor genes is a dangerous game, but Dr. Pomerantz said the genes could be inhibited for just a short period by applying the right dose of drug. When the drug has dissipated, the antitumor function of the gene would be restored. Finding the right combination of genes to suppress was a critical step in the new research. One of the two tumor suppressor genes is an ancient gene, known as Rb, which is naturally inactivated in newts and fish when they start regenerating tissue. Mammals possess both the Rb gene and a backup, called the Arf gene, which will close down a cancer-prone cell if Rb fails to do so.' Is regeneration nature's default, only turned off by our evolved defenses against cancer?"

Sentence Spacing — 1 Space or 2? 814

An anonymous reader noted an epic battle is waging, the likes of which has not been seen since we all agreed that tab indenting for code was properly two spaces. He writes "Do you hit the space bar two times between sentences, or only one? I admit, I'm from the typewriter age that hits it twice, but the article has pretty much convinced me to change. My final concern: how will my word processor know the difference between an abbr. and the end of a sentence (so it can stretch the sentence for me)? I don't use a capital letter for certain technical words (even when they start a sentence), making it both harder to programmatically detect a new sentence and more important to do so. What does the Slashdot community think?"

Denials Aside, Feds Storing Body Scan Images 560

The new generation of body scanners employed at airports (and many other places) can record detailed, anatomically revealing pictures of each person scanned, which is one reason they've raised the hackles of privacy advocates as well as ordinary travelers. Now, AHuxley writes "The US Transportation Security Administration claimed last summer that 'scanned images cannot be stored or recorded.' It turns out that some police agencies are storing the controversial images. The US Marshals Service admitted that it had saved ~35,314 images recorded with a millimeter wave system at the security checkpoint of a single Florida courthouse. The images were stored on a Brijot Gen2 machine. The Electronic Privacy Information Center, an advocacy group, has filed a lawsuit asking a federal judge to grant an immediate injunction to stop the TSA's body scanning program."

Free Software, a Matter of Life and Death 197

ChiefMonkeyGrinder writes "Software on medical implants is not open to scrutiny by regulatory bodies. Glyn Moody writes: 'Software with the ability to harm as well as help us in the physical world needs to be open to scrutiny to minimise safety issues. Medical devices may be the most extreme manifestation of this, but with the move of embedded software into planes, cars and other large and not-so-large devices with potentially lethal side-effects, the need to inspect software there too becomes increasingly urgent.' A new report 'Killed by Code: Software Transparency in Implantable Medical Devices' from the Software Freedom Law Center points out that, as patients grow more reliant on computerized devices, the dependability of software is a life-or-death issue. 'The need to address software vulnerability is especially pressing for Implantable Medical Devices, which are commonly used by millions of patients to treat chronic heart conditions, epilepsy, diabetes, obesity, and even depression.' Will making the source code free to scrutiny address the issue of faulty devices?"

Major Flaws Found In Recent BitTorrent Study 167

Caledfwlch writes with a followup to news we discussed a couple days ago about a study that found only 0.3% of torrents to be legal. (A further 11% was described as "ambiguous.") TorrentFreak looked more deeply into the study and found a number of flaws, suggesting that the researchers' data may have been pulled from a bogus tracker. Quoting: "Here's where the researchers make total fools out of themselves. In their answer to the question they refer to a table of the top 10 most seeded torrents. ... the most seeded file was uploaded nearly two years ago (The Incredible Hulk) and has a massive 1,112,628 seeders. The torrent in 10th place is not doing bad either with 277,043 seeds. All false data. We're not sure where these numbers originate from but the best seeded torrent at the moment only has 13,739 seeders; that's 1% of what the study reports. Also, the fact that the release is nearly two years old should have sounded some alarm bells. It appears that the researchers have pulled data from a bogus tracker, and it wouldn't be a big surprise if all the torrents in their top 10 are actually fake." They also take a cursory look at isoHunt, finding that 1.5% of torrent files come from Jamendo alone, "a site that publishes only Creative Commons licensed music."

LHC To Idle All Accelerators In 2012 117

sciencehabit writes "Particle physicists and science fans everywhere knew that the European particle physics laboratory, CERN, near Geneva, Switzerland, would shut down the Large Hadron Collider (LHC), the world's largest atom smasher, for all of 2012 for repairs. Many expected that the shutdown would stretch to more than a year, which CERN officials confirmed today. But most probably did not expect CERN to idle all its other accelerators at the same time, shutting down a variety of smaller projects and forcing hundreds of scientists not working on the LHC to take an unanticipated break in data taking. The longer shutdown could be a chance for US scientists working on the Tevatron at Fermilab in Batavia, Illinois, if researchers there can persuade lab management to keep the machine going instead of shutting it down in 2011 as currently planned." Reader suraj.sun notes other CERN news making the rounds right now about plans for the International Linear Collider, a 31-kilometer-long collider designed to complement the LHC. Construction on the ILC could begin as soon as 2012.

Behind the Special Effects of Inception 196

Lanxon writes "Wired has a behind the scenes look at how Inception's reality-distorting special effects sequences were shot, in an interview with Chris Corbould — the man 'prized for his ability to stage a real-life tank chase in St. Petersburg (GoldenEye), to flip a working juggernaut down a narrow Chicago street (The Dark Knight), and to build a working Batmobile that can do 30-metre jumps without the aid of a single post-production pixel.'" Hopefully most of you who intend to see Inception have already seen it by now, so you don't have to worry about spoilers. It's getting pretty much universal praise.

Why You Never Ask the Designers For a Favor Screenshot-sm 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.

Jailbreaking iPhone Now Legal 423

whisper_jeff writes "The US government on Monday announced new rules making it officially legal for iPhone owners to 'jailbreak' their device and run unauthorized third-party applications, as well as the ability to unlock any cell phone for use on multiple carriers." The EFF has further details on this and some of the other legal protections granted in the new rules.

'Bloatware' Becoming a Problem On Android Phones 415

elrous0 writes "According to a recent article in Wired, consumers of many new Android devices (including Samsung's Vibrant and HTC's EVO) are complaining about the increasing presence of something that has plagued consumer PC's for years: Bloatware (or, to use the more kind euphemism, 'Pre-installed software' that the computer manufacturer gets paid to include on a new PC). Unfortunately the bloatware (aka 'crapware') that comes with these phones has a nasty quality not found on even the most bloated PC: it can't be removed. Many angry consumers have begun to complain openly about this disturbing trend."

Open Source GSM Cracking Software Released 112

angry tapir writes "The GSM technology used by the majority of the world's mobile phones will get some scrutiny at next week's Black Hat security conference. An open source effort to develop GSM-cracking software has released software that cracks the A5/1 encryption algorithm used by some GSM networks. Called Kraken, this software uses new, very efficient, encryption cracking tables that allow it to break A5/1 encryption much faster than before."

GOP Senators Move To Block FCC On Net Neutrality 709

suraj.sun writes "Seven Republican senators have announced a plan to curb the Obama administration's push to impose controversial Net neutrality regulations on the Internet." "The FCC's rush to take over the Internet is just the latest example of the need for fundamental reform to protect consumers," says Sen. Jim DeMint, who I'm sure truly only has the consumer's needs at heart — since his campaign contributions list AT&T in his top five donating organizations.

Tattoos For the Math and Science Geek? 1186

An anonymous reader writes "I've been thinking of getting a sleeve of math and science tattoos for quite a while now. With the money saved up, the only question remaining is, what equations/ideas should I get? I know for certain that I'm going to include some of Maxwell's equations, and definitely Ohm's Law. So, if you were going to put a tribute to the great math and science minds on your body forever, which ones would you choose?"
