Fuel Cell Marvel "Bloom Box" Gaining Momentum 562

Many sources are continuing to excitedly report on the latest in a long line of startups chasing the holy grail of power sources. This incarnation, the "Bloom Box" from Bloom Energy, promises a power-plant-in-a-box that you can literally put in your backyard, and has received backing from companies like eBay, Google, Staples, FedEx, and Walmart. CBS recently aired an exclusive interview with K.R. Sridhar about his shiny new box. "So what is a Bloom Box exactly? Well, $700,000 to $800,000 will buy you a 'corporate sized' unit. Inside the box are a unique kind of fuel cell consisting of ceramic disks coated with green and black 'inks.' The inks somehow transform a stream of methane (or other hydrocarbons) and oxygen into power, when the box heats up to its operating temperature of 1,000 degrees Celsius. To get a view of the cost and benefits, eBay installed 5 of the boxes nine months ago. It says it has saved $100,000 USD on energy since."

Correlation Found Between Brain Structure and Video Game Success 110

kghapa writes "Still want to argue that video games shrink your brain? While video games have been previously shown to stimulate brain activity and improve coordination skills, a recently published study has directly linked structures in the human brain with video game aptitude. And yes, apparently size does matter in this case. Quoting: '... each subject received 20 hours of training to play a video game specifically created for research purposes, called Space Fortress. It's basically an Asteroids-type arcade game, in which the object is to knock down and destroy an enemy fortress while dodging space mines. However, the game has lots of extra twists that require close attention. Some of the players were told to focus exclusively on running up a high score, while others were told to shift their priorities between several goals. The result? The subjects who had more volume in an area called the nucleus accumbens did significantly better in the early stages of training. Meanwhile, those who were well-endowed in different areas of the striatum, known as the caudate nucleus and putamen, handled the shifting strategies better.'"

Art with a Mathematical Twist 69

Euler points out a story about art created through mathematics. The Science News article covers selections from a recent exhibit, where over 40 artists gathered to show their work and the math behind it. The rest of the pieces are also viewable at the exhibit's website. "Michael Field, a mathematics professor at the University of Houston, finds artistic inspiration in his work on dynamical systems. A mathematical dynamical system is just any rule that determines how a point moves around a plane. Field uses an equation that takes any point on a piece of paper and moves it to a different spot. Field repeats this process over and over again--around 5 billion times--and keeps track of how often each pixel-sized spot in the plane gets landed on. The more often a pixel gets hit, the deeper the shade Field colors it."

Capsaicin Tested On Surgical Wounds 227

Ponca City, We Love You writes "Bite a hot pepper, and after the burn your tongue goes numb. The Baltimore Sun reports that Capsaicin, the chemical that gives chili peppers their fire, is being dripped directly into open wounds during highly painful operations, bathing surgically exposed nerves in a high enough dose to numb them for weeks. As a result patients suffer less pain and require fewer narcotic painkillers as they heal. 'We wanted to exploit this numbness,' says Dr. Eske Aasvang, a pain specialist who is testing the substance. Capsaicin works by binding to C fibers called TRPV1, the nerve endings responsible for long-lasting aching and throbbing pain. Experiments are under way involving several hundred patients undergoing various surgeries, including knee and hip replacements using an ultra-purified version of Capsaicin to avoid infection. Volunteers are under anesthesia so they don't feel the initial burn."

Why Can't I Buy A CableCARD Ready Set-Top Box? 240

Al E Usse writes "Ars Technica does a write up of the problems that were not solved by the July 1, 2007 integration ban on integrated security in your cable box. The goal was to get everyone on the same page by requiring standardized technology. Just the same, the cable companies aren't really playing ball. 'The companies who make the boxes don't seem interested in selling to consumers [and] cable companies still push their own branded devices.' The article covers some deep background on the whole CableCARD mess, and concludes with the current state of the market: 'Based on June 2007 figures from the cable industry, 271,000 CableCARDs have been deployed. That's an astonishingly low number. 58 percent of all US households with a TV subscribe to cable, according to the NCTA, which means that 65 million households have at least basic cable.'"

Astronomers Again Baffled by Solar Observations 299

SteakNShake writes "Once again professional astronomers are struggling to understand observations of the sun. ScienceDaily reports that a team from Saint Andrew's University announced that the sun's magnetic fields dominate the behavior of the corona via a mechanism dubbed the 'solar skeleton.' Computer models continue to be built to mimic the observed behavior of the sun in terms of magnetic fields but apparently the ball is still being dropped; no mention in the announcement is made of the electric fields that must be the cause of the observed magnetic fields. Also conspicuously absent from the press releases is the conclusion that the sun's corona is so-dominated by electric and magnetic fields because it is a plasma. In light of past and present research revealing the electrical nature of the universe, this kind of crippling ignorance among professional astrophysicists is astonishing."

Music Companies Mull Ditching DRM 318

PoliTech writes to mention an International Herald Tribue article that is reporting the unthinkable: Record companies are considering ditching DRM for their mp3 albums. For the first time, flagging sales of online music tracks are beginning to make the big recording companies consider the wisdom of selling music without 'rights management' technologies attached. The article notes that this is a step the recording industry vowed 'never to take'. From the article: "Most independent record labels already sell tracks digitally compressed in MP3 format, which can be downloaded, e-mailed or copied to computers, cellphones, portable music players and compact discs without limit. Partially, the independents see providing songs in MP3 as a way of generating publicity that could lead to future sales. Should one of the big four take that route, however, it would be a capitulation to the power of the Internet, which has destroyed their monopoly over the worldwide distribution of music in the past decade and allowed file-sharing to take its place."

Xerox Reveals Transient Documents 246

Heartless Gamer writes "Xerox has lifted the veil from some of its research and development work in the field of printing. They demoed the very intriguing 'transient documents.' These offer the prospect of reusable paper in the sense that the content is automatically erased after a period of time, ready for fresh printing. Inspired by the fact that many print outs have a life-span of a few hours (think of the emails you may print out just to read, or the content you proof read on the train journey back home), the specially prepared paper will preserve its content for up to 16 hours."
