Fermilab To Test Holographic Universe Theory 166

Posted by samzenpus from the getting-some-answers dept.
eldavojohn writes "Scientists at Fermilab have decided that it's high time they build a 'holometer' to test the smoothness of space-time. Theoretical physicists like Stephen Hawking have proposed that space-time is not smooth but it's been a lot of math and no actual data. The Fermilab team plans to build two relatively small devices that act as 'holographic interferometers' to measure the shaking or vibration in split beams of light traveling through a vacuum. If the team finds the shaking in their measurements and records them, the theory of a holographic universe will have some evidence of non-smoothness in space-time and perhaps a foothold in bringing light to the heavily debated theoretical physics."

OLPC Gets $5.6M Grant To Develop Tablet With Marvell 100

Posted by Soulskill from the one-hip-device-per-child dept.
tugfoigel writes "According to Xconomy, 'The One Laptop per Child Foundation and Santa Clara, CA-based semiconductor maker Marvell have cemented a partnership announced last spring, with Marvell agreeing to provide OLPC with $5.6 million to fund development of its next generation tablet computer. Nicholas Negroponte says the deal, signed in the past week or so but not previously announced, runs through 2011. "Their money is a grant to the OLPC Foundation to develop a tablet or tablets based on their chip," he says. The OLPC tablet ... is known as the XO 3 because it represents the third-generation of the XO laptop currently sold by OLPC (the foundation scrapped plans for its e-book-like XO 2 computer and is moving straight to the tablet). ... The deal, he says, means the tablet's development is "fully funded."'"

15-Year-Old Boy Fitted With Robotic Heart 241

Posted by Soulskill from the stay-away-from-nausicaans,-kid dept.
An anonymous reader writes "What do you do when a 15-year-old boy is close to death and ineligible for a heart transplant? If you're Dr. Antonio Amodeo you turn to an artificial solution and transplant a robotic heart, giving the boy another 20-25 years of life. The Italian boy in question suffers from Duchenne muscular dystrophy, which rapidly degenerates the muscles and eventually leads to death. Having such a disease renders the boy ineligible for a heart transplant, meaning almost certain death without an alternative solution. Dr. Amodeo found such an alternative in the form of a 90-gram, fully-robotic heart that took 10 hours to fit inside the boy's left ventricle. It is a permanent solution offering as much as 25 years of life and is powered by a battery worn as a belt."

Self-Assembling Photovoltaic Cells 103

Posted by timothy from the some-assembly-automatic dept.
dhj writes "MIT scientists have developed a self-assembling photovoltaic cell in a petri dish. Phospholipids (think cell membranes) form disks which act as the structural support for light responsive molecules. Carbon nanotubes help to align the disks and conduct electricity generated by the system with 40% efficiency. The assembly process is reversible using surfactants to break up the phospholipids. When filters are used to remove the surfactants the system reassembles with no loss of efficiency even over multiple assembly/disassembly cycles. The results were published September 5th in Nature Chemistry."

Researchers Demo ASP.NET Crypto Attack 98

Posted by timothy from the theoretical-no-more dept.
Trailrunner7 writes "The crypto attack against ASP.Net Web apps has gotten a lot of attention this week, and with good reason. Microsoft on Friday night issued a security advisory about the bug, warning customers that it poses a clear danger to their sites. Also on Friday, the researchers who found the bug and implemented the attack against it released a slick video demo of the attack, clearly showing the seriousness of the problem and how simple it is to exploit with their POET tool."

Distinguishing Encrypted Data From Random Data? 467

Posted by timothy from the is-this-a-solved-problem? dept.
gust5av writes "I'm working on a little script to provide very simple and easy to use steganography. I'm using bash together with cryptsetup (without LUKS), and the plausible deniability lies in writing to different parts of a container file. On decryption you specify the offset of the hidden data. Together with a dynamically expanding filesystem, this makes it possible to have an arbitrary number of hidden volumes in a file. It is implausible to reveal the encrypted data without the password, but is it possible to prove there is encrypted data where you claim there's not? If I give someone one file containing random data and another containing data encrypted with AES, will he be able to tell which is which?"

US Gov't Makes a Mess of Classifying Sensitive Data 100

Posted by Soulskill from the bureaucracy-at-its-finest dept.
coondoggie writes "Protecting and classifying sensitive information such as social security numbers shouldn't be that hard, but (perhaps not surprisingly) the US government has elevated complicating that task to an art form. It seems that designating, safeguarding, and disseminating such important information involves over 100 unique markings and at least 130 different labeling or handling routines, reflecting a disjointed, inconsistent, and unpredictable system for protecting, sharing, and disclosing sensitive information." This was the conclusion of a recent report (PDF) by the Government Accountability Office, which also "found areas where sensitive information is not fully safeguarded and thus may remain at risk of unauthorized disclosure or misuse."

Salesforce Uses Chatter To Monitor Employees 82

Posted by timothy from the eavesdropping-on-their-own-eaves dept.
storagedude writes "At the launch of Chatter Mobile this week, Salesforce.com CEO Marc Benioff said he has been using the Facebook-like business service to monitor employee communications and identify a 'secret network' of employees who are influential in driving the business. Asked if employees felt like they were being spied on by Big Brother, Benioff replied, 'There are certain things appropriate in a business environment. We're not talking about a tea party, we're talking about how to get things fixed.' With 20,000 companies already using the three-month-old service, it is no doubt being put to similar use elsewhere. While Salesforce's use of Chatter to monitor employees appears to be legal, the issue underscores just how much social networks can be mined for information — even for things they weren't intended for."

Hacker Teaches iPhone Forensics To Police 193

Posted by samzenpus from the strange-bedfellows dept.
Ponca City, We love you writes "The Mercury News reports that former hacker Jonathan Zdziarski has been tapped by law-enforcement agencies nationwide to teach them just how much information is stored in iPhones — and how to get it. 'These devices are people's companions today,' says Zdziarski. 'They're not mobile phones anymore. They organize people's lives. And if you're doing something criminal, something about it is probably going to go through that phone.' For example, every time an iPhone user closes out of the built-in mapping application, the phone snaps a screenshot and stores it. Savvy law-enforcement agents armed with search warrants can use those snapshots to see if a suspect is lying about whereabouts during a crime."

GE Closes Last US Light Bulb Factory 797

Posted by samzenpus from the bright-idea dept.
pickens writes "The Washington Post reports that last major GE factory making ordinary incandescent light bulbs in the US is closing this month, marking a small, sad exit for a product and company that can trace their roots to Thomas Alva Edison's innovations in the 1870s. What made the plant vulnerable is, in part, a 2007 energy conservation measure passed by Congress that set standards essentially banning ordinary incandescents by 2014 but rather than setting off a boom in the US manufacture of replacement lights, the leading replacement lights are compact fluorescents, or CFLs, which are made almost entirely overseas. GE developed a plan to see what it would take to retrofit a plant that makes traditional incandescents into one that makes CFLs but even with a $40 million investment the new plant's CFLs would have cost about 50 percent more than those from China. 'Everybody's jumping on the green bandwagon,' says Pat Doyle, 54, who has worked at the plant for 26 years. But 'we've been sold out. First sold out by the government. Then sold out by GE.'"

Using Wisdom Teeth To Make Stem Cells 82

Posted by samzenpus from the spare-parts dept.
An anonymous reader writes "For most people, wisdom teeth are not much more than an annoyance that eventually needs to be removed. However, a new study appearing in the September 17 Journal of Biological Chemistry shows that wisdom teeth contain a valuable reservoir of tissue for the creation of stem cells; thus, everyone might be carrying around his or her own personal stem-cell repository should he or she ever need some. Groundbreaking research back in 2006 revealed that inducing the activity of four genes in adult cells could 'reprogram' them back into a stem-cell-like state; biologically, these induced-pluripotent stem cells are virtually identical to embryonic stem cells, opening up a new potential avenue for stem-cell therapy whereby patients could be treated with their own stem cells."

crimeandpunishment writes "A federal judge has ruled that the company holding a movie copyright can subpoena the names of people who are accused of illegally downloading and distributing the film. The judge ruled that courts have maintained that once people convey subscriber information to their Internet service providers, they no longer have an expectation of privacy."

BP's Gulf Spill Report Shows String of Failures 181

Posted by CmdrTaco from the commence-the-finger-pointing dept.
eldavojohn writes "News is out of BP's report on the gulf spill that shifts some of the blame on to other companies like Transocean that worked with BP in erecting the Deepwater Horizon rig. If you were affected by the spill, you might find the video, executive summary and 193-page report an interesting read. The summary outlines six or seven major failures in safety and engineering that all built up to the deaths of eleven workers and widespread contamination of the gulf. From incorrectly using seawater instead of drilling fluid to misinterpreting pressure test results, this report is just BP's side of the story as the blowout preventer has been pulled up and is still on its way to NASA where it will be analyzed by government investigators who will be able to compile their own report."
