StonyandCher writes "Sony has created a battery that produces electricity by breaking down sugar. The bio cell, which measures 39 millimeters cubed, delivers 50mW — a world record for such a cell, according to the company. 'In the bio cell sugar-digesting enzymes at the anode extract electrons and hydrogen ions from the glucose. The hydrogen ions pass through a membrane separator to the cathode where they absorb oxygen from the air to produce water as a byproduct. The electrons flow around the circuit outside the device producing the electricity needed to power it.'"

Cain writes to mention that a couple of MIT students would like to harness the mechanical power of large groups of people. "A Crowd Farm in Boston's South Station railway terminal would work like this: A responsive sub-flooring system made up of blocks that depress slightly under the force of human steps would be installed beneath the station's main lobby. The slippage of the blocks against one another as people walked would generate power through the principle of the dynamo, a device that converts the energy of motion into that of an electric current."

Late-Eight writes "Scientists at the Georgia Institute of Technology are working on a new type of nanogenerator that could draw necessary energy from flowing blood in the human body. The hope is to incorporate the new nanogenerator into biosensors, environmental monitoring devices and even personal electronics that will require no fuel source, internal or external. Once completed, this new cellular engine could find various applications, even beyond medicine."

Scientists from MIT and Boston University are creating viruses that will wipe out "biofilms" that contain harmful bacteria on surfaces of the human body and industrial or medical devices. "Bacterial biofilms can form almost anywhere, even on your teeth if you don't brush for a day or two. When they accumulate in hard to reach places such as the insides of food processing machines or medical catheters, however, they become persistent sources of infection. These bacteria excrete a variety of proteins, polysaccharides, and nucleic acids that together with other accumulating materials form an extracellular matrix, or in Lu's words, a "slimy layer," that encases the bacteria. Traditional remedies such as antibiotics are not as effective on these bacterial biofilms as they are on free-floating bacteria. In some cases, antibiotics even encourage bacterial biofilms to form."

mattnyc99 writes "Today marks the 25th anniversary of the release of Blade Runner, Ridley Scott's dark vision of the future that changed the future of filmmaking and still stands up today, argues Adam Savage of The MythBusters (and the F/X crews of The Matrix and Star Wars). Between the "lived-in science fiction," pre-CGI master models, futuristic cityscapes and tricked-out cars, don't you agree? And after we got the first official glimpse of him from Indiana Jones 4 this weekend, isn't Harrison Ford still the man?"

Killam0n takes note of a story in CNN Money on progress in controlling computers via brainwaves. From an aspirin-sized implant a quadriplegic is now using to play computer games, the article extrapolates out to a near future in which we will all be wearing headband computers and IM'ing one another as if telepathically. "Two years ago, a quadriplegic man started playing video games using his brain as a controller. That may just sound like fun and games for the unfortunate, but really, it spells the beginning of a radical change in how we interact with computers — and business will never be the same. Someday, keyboards and computer mice will be remembered only as medieval-style torture devices for the wrists. All work — emails, spreadsheets, and Google searches — will be performed by mind control."

An anonymous reader writes "As Slashdot recently reported, last week saw the latest showdown between HD DVD and Blu-ray, with both formats bringing out the big guns in terms of high profile format-exclusive disc releases. In one corner were the Blu-ray exclusive releases of the first two 'Pirates of the Caribbean' films on Blu-ray — in the other, the HD DVD exclusive releases of 'The Matrix' Trilogy. So who won the sales battle? According to preliminary estimates, this one goes to 'Pirates' in a big way. The two 'Pirates' flicks sold an estimated 47,000 units, while the 'Matrix' sets sold just about 13,900 units. Is this an indication of movie quality, or another notch in the belt for the Blu-ray format?"

The circle is now complete. With Turbine's release of Lord of the Rings Online: The Shadows of Angmar (LOTRO), the Massively Mutliplayer game figuratively eats the tail of its originator in ouroboros-like fashion. Tolkien's work begat Dungeons and Dragons, the PC gaming market, CRPGs, and finally Massive games, and last month's release of LOTRO beautifully reconnects the future with the past. Replacing dice-wielding friends around a table has even, wonder of wonders, been done well. Polished gameplay and cutting-edge graphics abound; In direct contrast to the lackluster response to Turbine's other MMOG, Dungeons and Dragons Online, Lord of the Rings Online has had an overwhelmingly positive reaction from fans. Read on for my notes from the experience of trying on Hobbit feet for a month, and a few words about why LOTRO's quality is notable and highly encouraging.

An anonymous reader writes "Choosing sides in the high-def format war becomes that much harder today, as two powerhouse movie franchises hit store shelves on opposing formats. Exclusive to Blu-ray are the first two 'Pirates of the Caribbean' flicks, while exclusive to HD DVD are two different configurations of the 'Matrix' Trilogy. So which format wins this battle? According to High-Def Digest, this one's a draw. The article has capsule reviews of the four releases ('The Ultimate Matrix Collection' & 'The Complete Matrix Trilogy' on HD DVD, and 'POTC: Curse of the Black Pearl' & 'POTC: Dead Man's Chest' on Blu-ray) with links to excruciatingly in-depth reviews. In the end the site says both sets of releases boast benchmark video and audio, but a preponderance of standard-def supplements prevent all of the above from being the perfect high-def package."

aeoneal sends us to PhysicsWeb for news guaranteed to induce headache in those wedded to the reality of, well, reality. Researchers from the University of Vienna have shown the violation of a stronger form of Bell's inequality known as Leggett's inequality. The result means that we must not only give up Einstein's hope of "no spooky action at a distance," we must also give up (some of) the idea that the world exists when we are not looking. From the article: "[Studies] have ruled out all hidden-variables theories based on joint assumptions of realism, meaning that reality exists when we are not observing it; and locality, meaning that separated events cannot influence one another instantaneously. But a violation of Bell's inequality does not tell specifically which assumption — realism, locality, or both — is discordant with quantum mechanics." From the Nature abstract: "Our result suggests that giving up the concept of locality is not sufficient to be consistent with quantum experiments, unless certain intuitive features of realism are abandoned." Only subscribers to Nature, alas, can know what features those are, as PhysicsWeb doesn't tell us.

zdude255 writes "Wired is running an article exploring several studies of giving the human brain 'new input devices.' From seeing with your sense of touch to entirely new senses such as sensing direction intuitively, the human brain seems to be capable of interpreting and using new data on the fly. This offers many applications from pilots being able to sense the plane's orientation to the potential recovery of patients with blindness or ear damage. (which helps balance).'It turns out that the tricky bit isn't the sensing. The world is full of gadgets that detect things humans cannot. The hard part is processing the input. Neuroscientists don't know enough about how the brain interprets data. The science of plugging things directly into the brain -- artificial retinas or cochlear implants -- remains primitive. So here's the solution: Figure out how to change the sensory data you want -- the electromagnetic fields, the ultrasound, the infrared -- into something that the human brain is already wired to accept, like touch or sight.'"

Da Massive writes with a link to ComputerWorld coverage of a unique gadget shown at this past week's CeBit show. The company g.tec was showing off a brain/computer interface (BCI) in one corner of the trade hall. The rig, once placed on your head, detects the brain's voltage fluctuations and can respond appropriately. This requires training, where "the subject responds to commands on a computer screen, thinking 'left' and 'right' when they are instructed to do so ... Another test involves looking at a series of blinking letters, and thinking of a letter when it appears." Once the system is trained, you can think letters at the machine and 'type' via your thoughts. Likewise, by thinking directions you can move objects around onscreen. The article provides some background on the history of g.tec's BCI, and suggests possible uses for the technology in the near future.

Ant writes "Neatorama lists nine laws of physics that don't apply in Hollywood (movies and television/TV shows). In general, Hollywood filmmakers follow the laws of physics because they have no other choice. It's just when they cheat with special effects that people seem to forget how the world really works..."

Carl Bialik from WSJ writes "A Hong Kong health club is hoping that a car battery, some StairMasters and dozens of gym rats can help ease the world's energy problems. It is just one of a wave of projects that are trying to tap the power of the human body, the Wall Street Journal reports. The article explains the impetus behind the project: 'The human power project at California Fitness was set in motion by Doug Woodring, a 41-year-old extreme-sports fanatic and renewable-energy entrepreneur, who pitched the experiment to the gym's management last May. "I've trained my whole life, and many megawatts have been wasted," says Mr. Woodring, who has worked out at the Hong Kong gym for years. "I wanted to do something with all that sweat."'"

sporkme has handed us a link to a New Scientist article. The piece outlines the development of a new substance reported to be stiffer than diamond. A team of scientists from Washington, Wisconsin, and Germany combined the ceramic barium titanate and white-hot molten tin with an ultrasonic probe. The new material was, in some tests, almost 10x more resistant to bending than diamond. Composite materials researcher Mark Spearing of Southampton University comments on the result: "The material's stiffness results from the properties of the barium titanate pieces, Spearing says. As the material cools, its crystal structure changes, causing its volume to expand. 'Because they are held inside the tin matrix, strain builds up inside the barium titanate,' Spearing explains, 'at a particular temperature that energy is released to oppose a bending force.'"

moon_monkey writes "Researchers at the University of Pennsylvania have developed a 'neural extension cord' by growing neurons attached to a microchip. The cord is made by gradually moving two batches of neurons apart, as they naturally grow towards one another. This biological 'data cable' could then interface with the brain once implanted, the researchers say." From the article: "...in the long run, it may not be necessary to interface directly with nerves at all. 'In Europe most researchers in this field are using non-invasive EEG,' [an outside researcher] explains... 'The signals are weaker so more complex processing is needed, but not having to perform surgery on the nervous system has many advantages,' [he] says."

1up has a look at Arkane Studios' extremely ambitious new project. Called The Crossing, the FPS title looks to combine single and multi-player modes in a new way. From the article: "In the simplest sense, story missions are single-player shooting with an exception: Naturally intelligent human opponents take the place of A.I. There are two types of players: Elites and skirmishers. Elites are gamers playing the game in story mode. They're beefed up, heavily armored, and heavily armed. They have to be able to hold their own against a swarm of skirmish players. Skirmishers are gamers who typically play on multiplayer maps: well-trained, rank-and-file soldiers playing primarily to have some quick fun and increase their rank through defeating the occasional Elite. Skirmish players can also invade story maps and 'possess' A.I.s ala Agent Smith in The Matrix." So even if you're playing through the story, you'll still be challenged by the 'NPCs', all of whom will be played by a real-life human. Sounds like it could either be awesome or a total flop. Which side are you leaning on?

Steve Cerruti asks: "My credit union is implementing multi-factor authentication for online banking. They are following guidelines provided by the Federal Financial Institutions Examination Council as outlined in Authentication in an Internet Banking Environment (PDF). As you are already required to enter a password, 'something you know' is covered. 'Something you are' has significant technical hurdles while 'something you have' is familiar to credit unions in the form of ATM cards. My credit union chose to implement 'something you have' as a two dimensional lookup table that they email to an address you supply when you initially log in to the online banking service, further access is blocked until you enter a code from the table. New Measures to Make Online Access Safer describes the plan and a short video (FLV) provides further details." For the security conscious among us, do you think this is a decent way to implement the 'something you have' portion of a well secured system, or are there better ways to do it?

eldavojohn writes to point out recent research using nuclear magnetic resonance (NMR) imagery that shows that certain nuclear waste storage containers may not be as safe as previously thought. From the article: "[R]adiation emitted from [plutonium] waste could transform one candidate storage material into less durable glass after just 1,400 years — much more quickly than thought... The problem is that the radioactive waste damages the matrix that contains it. Many of the waste substances, including plutonium-239, emit alpha radiation, which travels for only very short distances (barely a few hundredths of a millimeter) in the ceramic, but creates havoc along the way."

Johan Louwers writes "Robots will crawl tubes in a short while to investigate power cables running in the tubes to make sure they are still undamaged or in need for a repair. The Robotic Cable Inspection System is developed by Alexander Mamishev, an assistant professor of electrical engineering at the University of Washington. Making use of infrared thermal analysis and acoustic partial discharge analysis, the robot will be checking mile after mile of cable while crawling his way in the tubes."
