Seeing With Your Skin? 138

Iddo Genuth writes to tell us that a researcher from Tel Aviv University is exploring the possibility that humans may be able to "see" via their skin. Professor Leonid Yaroslavsky hopes to utilize this possible technology to find solutions for the blind in addition to new types of image capture that might be able to work where conventional lenses fail. Unfortunately he has a long uphill battle ahead to convince others that his theories are possible. "The lenses currently used for optics-based imaging have many problems. They only work within a limited range of electromagnetic radiation. Relatively, these are still costly devices greatly limited by weight and field of view. The imaging Professor Yaroslavsky has in mind has no lenses and he believes the devices can be adapted to any kind of radiation and wavelength. They could essentially work with a 360-degree field of view and their imaging capability will only be determined by computer power rather than the laws of light diffraction."

7th-Grader Designs Three Dimensional Solar Cell 719

Hugh Pickens writes "12-year-old William Yuan's invention of a highly-efficient, three-dimensional nanotube solar cell for visible and ultraviolet light has won him an award and a $25,000 scholarship from the Davidson Institute for Talent Development. 'Current solar cells are flat and can only absorb visible light'" Yuan said. 'I came up with an innovative solar cell that absorbs both visible and UV light. My project focused on finding the optimum solar cell to further increase the light absorption and efficiency and design a nanotube for light-electricity conversion efficiency.' Solar panels with his 3D cells would provide 500 times more light absorption than commercially-available solar cells and nine times more than cutting-edge 3D solar cells. 'My next step is to talk to manufacturers to see if they will build a working prototype,' Yuan said. "If the design works in a real test stage, I want to find a company to manufacture and market it.""

IAU Names Fifth Dwarf Planet Haumea 94

Kligat writes "The International Astronomical Union has renamed the dwarf planet Haumea and its two moons Hi'iaka and Namaka, after the Hawaiian fertility goddess, the patron goddess of Hawaii, and a water spirit. The cigar-shaped body is speculated to have resulted from its short rotational period of only four hours. Holding up the reclassification of the body as a dwarf planet was a dispute over its discovery between the groups of José Luis Ortiz Moreno and Michael E. Brown."

Gamers Are Fitter (and Sadder) Than You Think 341

missb writes "According to NewScientist.com, online gamers are no 'couch potatoes'. US researchers quizzed players of the role-playing game EverQuest II, and found adult gamers to be in better physical condition than the average American. The downside, however, was the gamers reported more cases of depression and substance abuse than their compatriots."

How Do Geeks Exercise? 1806

An anonymous reader writes "I have always been thin but all the sitting in front of the PC is taking its toll now that I'm getting older. I have begun to get a little heavier around the waist. I don't eat a lot but the weight seems to stay on these days. Most of the time I don't have the luxury of just getting out of the house/office. And being an introvert, I'm not enamored of the idea of exercising in full view of *shudder* people. I regularly do press-ups (60 per night) and sit-ups (30 per night) and some fetching and carrying, but that is all and these days it isn't enough. I need a solid and effective routine that will tone all my muscle groups efficiently. Do any Slashdotters have a regular workout routine that can be performed in the privacy of the home to stave off those pounds?"

"Vetrolium" From Agricultural Waste 438

junctionvin writes "The company Sustainable Power Corp. claims to have created a form of bio-crude oil from agricultural refuse. They use agro-waste from cracked soy beans, rice and cotton seed hulls, grain sorghum, milo, and jatropha and turn it into bio-crude oil. This crude can then be further refined into everything from gasoline to jet fuel and just about every petrochemical in between. The CEO is quoted: 'Our biggest problem is that we are too good to be true. We can literally replace every gallon of gasoline, diesel and jet fuel in the United States using just 12 percent of the waste byproducts in the country.' They also claim that their fuel burns to near 100 percent efficiency." The article doesn't mention what price the "vetrolium" would command in today's market or going forward, except to report the CEO's promise "to one day sell his gasoline for $1 less than the pump price for regular fuel, no matter what the cost. 'Even if it's $2 per gallon, I'll sell mine for $1,"' he said."

Do Women Write Better Code? 847

JCWDenton writes "The senior vice-president of engineering for computer-database company Ingres-and one of Silicon Valley's highest-ranking female programmers-insists that men and women write code differently. Women are more touchy-feely and considerate of those who will use the code later, she says. They'll intersperse their code ... with helpful comments and directions, explaining why they wrote the lines the way they did and exactly how they did it. The code becomes a type of 'roadmap' for others who might want to alter it or add to it later, says McGrattan, a native of Ireland who has been with Ingres since 1992. Men, on the other hand, have no such pretenses. Often, 'they try to show how clever they are by writing very cryptic code,' she tells the Business Technology Blog. 'They try to obfuscate things in the code,' and don't leave clear directions for people using it later. "

Net Neutrality vs. Technical Reality 251

penciling_in writes "CircleID has a post by Richard Bennett, one of the panelists in the recent Innovation forum on open access and net neutrality — where Google announced their upcoming throttling detector. From the article: 'My name is Richard Bennett and I'm a network engineer. I've built networking products for 30 years and contributed to a dozen networking standards, including Ethernet and Wi-Fi. I was one of the witnesses at the FCC hearing at Harvard, and I wrote one of the dueling Op-Ed's on net neutrality that ran in the Mercury News the day of the Stanford hearing. I'm opposed to net neutrality regulations because they foreclose some engineering options that we're going to need for the Internet to become the one true general-purpose network that links all of us to each other, connects all our devices to all our information, and makes the world a better place. Let me explain ...' This article is great insight for anyone for or against net neutrality."

Google Browser Sync To Be Discontinued 195

Dude With An Afro writes "What could have been a great Google project is now history. For those who never used it, Google Browser Sync was a Firefox extension that synchronized your bookmarks, web history, browser sessions and passwords across multiple computers by temporarily saving them to Google's servers. According to the Google Browser Sync team: 'It was a tough call, but we decided to phase out support for Browser Sync. Since the team has moved on to other projects that are keeping them busy, we don't have time to update the extension to work with Firefox 3 or to continue to maintain it.' For all of those who fell in love with Google's Browser Sync, our only hope now is to resort to poorly maintained 3rd party extensions without Google's blessing." While it was undoubtedly a useful utility, the argument can also be made that it wasn't the most secure extension in the world, what with having your personal data kept on Google's servers and shot around the internet.

The SUV Is Dethroned 1234

Wired's Autopia blog documents what we all knew was coming: rising gas prices have killed off the SUV. Auto industry watchers had predicted that the gas guzzlers in the "light truck" category would lose the ascendancy by 2010; no one expected their reign to end in a month, in the spring of 2008. Toyota, GM, Ford, and now Nissan have announced they will scale back truck and SUV production and ramp up that of smaller passenger cars. Of course there will always be a market for this class of vehicle, but its days on the top of the sales charts are done. "'All of our previous assumptions on the full-size pickup truck segment are off the table,' Bob Carter, Toyota division sales chief said last week during a conference call with reporters. Translation — we have no idea how low they'll go."

New Robots Developed To Climb Walls 110

An anonymous reader writes "SRI International, a nonprofit research and development organization, has developed a new technology that enables some robots to scale walls. The wall-climbing robots could be a boon for the US military, which could use them on reconnaissance or other missions in war zones, said Philip von Guggenberg, director of business development for SRI International, adding that the independent group has received some funding from DARPA, the technology research arm of the Pentagon. Von Guggenberg said that the new electrical adhesive technology called compliant electroadhesion, provides an electrically controllable way to stick machines to a wall. So what can they do? That adhesion lets the robots, using either feet or tracks, scale a vertical wall. They can even climb walls covered in dust and debris, or made out of concrete, wood, steel, glass, drywall, and brick. Good news is that regular robots, especially those with tracks, can be retrofitted with the technology and turned into wall climbers. Maybe if the kids are good, they'll get one for Christmas."

Singapore Firm Claims Patent Breach By Virtually All Websites 481

An anonymous reader writes "A Singapore firm, VueStar has threatened to sue websites that use pictures or graphics to link to another page, claiming it owns the patent for a technology used by millions around the world. The company is also planning to take on giants like Microsoft and Google. It is a battle that could, at least in theory, upend the Internet. The firm has been sending out invoices to Singapore companies since last week asking them to pay up."

Hubble Survey Finds Half of the Missing Matter 189

esocid sends along the news that scientists believe they have found about half the missing matter in the universe. The matter we can see is only about 1/8 of the total baryonic matter believed to exist (and only 1/200 the mass-energy of the visible universe). This missing matter is not to be confused with "dark matter," which is thought to be non-baryonic. The missing stuff has been found in the intergalactic medium that extends essentially throughout all of space, from just outside our galaxy to the most distant regions of space. "'We think we are seeing the strands of a web-like structure that forms the backbone of the universe,' Mike Shull of the University of Colorado explained. 'What we are confirming in detail is that intergalactic space, which intuitively might seem to be empty, is in fact the reservoir for most of the normal, baryonic matter in the universe.'"

Have You Changed Your Opinion On eBook Readers? 569

An anonymous reader writes "The Kindle made waves when it came out, but they've now had the chance to calm. How many of you have been using your eBook readers since you've received them? How many of you forgot you had one, and how many of you swear by your reader? I like my single-purpose (well, dual — music player) Sony Reader because I actually use it to read, rather than multitasking myself to death. Is this technology as convenient and useful as you expected?" If not, what refinements or improvements would reKindle your interest?
