An anonymous reader writes "If we break a bone it can take weeks or even month to heal depending on the type and severity of the break. In some extreme cases the complexity of the fracture can make it impossible to heal properly. Researchers at the University of Georgia Regenerative Bioscience Center have come up with a new solution for healing broken bones that cuts recovery time to days. It relies on the use of stem cells that contain a bone generating protein. These cells are injected in gel form directly into the area of the broken bone, where they quickly get to work forming new bone. The end result is very rapid recovery, possibly sidestepping the muscle atrophy that can come with long bone healing times. The gel has been proven to work on animals as big as a sheep and has funding from the DoD. Lets hope it is proven to work on humans in the coming years."

astroengine writes "So it turns out U.S. radars weren't to blame for the unfortunate demise of Russia's Phobos-Grunt Mars sample return mission — it was a computer programming error that doomed the probe, a government board investigating the accident has determined." According to the Planetary Society Blog's unofficial translation and paraphrasing of the incident report, "The spacecraft computer failed when two of the chips in the electronics suffered radiation damage. (The Russians say that radiation damage is the most likely cause, but the spacecraft was still in low Earth orbit beneath the radiation belts.) Whatever triggered the chip failure, the ultimate cause was the use of non-space-qualified electronic components. When the chips failed, the on-board computer program crashed."

New submitter Morganth writes "According to New Scientist, researchers at DARPA are investing efforts in transcranial direct current stimulation (tDCS) machines to cut the time it takes to train snipers. From the article: 'a 2-milliamp current will run through the part of the brain associated with object recognition — an important skill when visually combing a scene for assailants.' The story also gives a nice explanation on the psychology of 'flow' — the state that experts tend to enter (e.g. programmers, tennis players, pianists) when focusing on their work."

New submitter mwehle writes with this bit from Ars Technica: "Google's Chrome browser will stop relying on a decades-old method for ensuring secure sockets layer certificates are valid after one of the company's top engineers compared it to seat belts that break when they are needed most. The browser will stop querying CRL, or certificate revocation lists, and databases that rely on OCSP, or online certificate status protocol, Google researcher Adam Langley said in a blog post published on Sunday. He said the services, which browsers are supposed to query before trusting a credential for an SSL-protected address, don't make end users safer because Chrome and most other browsers establish the connection even when the services aren't able to ensure a certificate hasn't been tampered with."

Sparrowvsrevolution writes "Hackers linked with Anonymous leaked another 1.26 gigabytes of Symantec's data Monday night, what they say is the source code company's PCAnywhere program. More interestingly, also posted a long private email conversation that seems to show a Symantec exec offering the hackers $50,000 to not leak the company's data and to publicly state they had lied about obtaining it. Symantec has responded by revealing that in fact, the $50,000 offer had been a ruse, and the 'Symantec exec' was actually a law enforcement agent trying to trace the hackers. It adds that all the information the hackers have released, including a 2006 version of Norton Internet Security, is outdated and poses no threat to the company or its customers. Symantec says the Anonymous hackers began attempting to extort money from the company in mid-January, and it responded by contacting law enforcement, though it won't comment on the results of the fake payoff sting while the investigation is still ongoing."

vikingpower writes "The Little Ice Age, lasting from the end of the Middle Age into the 17th century, may very likely have been caused by the combined effects of four major volcanic eruptions and increased sunlight reflection by increasing sea ice, the so-called Albedo effect. ... The University of Boulder has a press release with maps and photographs. Bette Otto-Bliesner, one of the scientists behind the 'volcano + sea ice' thesis, fields an earnest warning against drawing conclusions too quickly from this research: 'I think people might look at the Little Ice Age and think that all we need to save us from rising temperatures are some volcanic eruptions or the geo-engineering equivalent [...] But when you see what happened when global temperatures dropped by just one degree and you look at current predictions of six or seven degree increases for the future, you realize how precarious things are for life as we know it.'"

Trailrunner7 writes "Adobe, which has spent the last few years trying to dig out of a deep hole of vulnerabilities and buggy code, is making a major change to Flash, adding a sandbox to the version of the player that runs in Firefox. The sandbox is designed to prevent many common exploit techniques against Flash. The move by Adobe comes roughly a year after the company added a sandbox to Flash for Google Chrome. Flash, which is perhaps the most widely deployed piece of software on the Internet, has been a common attack vector for several years now, and the attacks in some cases have been used to get around exploit mitigations added by the browser vendors. The sandbox is designed to prevent many of these attacks by not allowing exploits against Flash to break out into the browser itself."

An anonymous reader writes "Scientists at the Universities of Southampton and Penn State have found a way to embed electronic components into optical fibers, in a breakthrough that could lead to the creation of super high-speed telecommunications networks. Rather than trying to merge flat chips with round optical fibers, the team of scientists used high-pressure chemistry techniques to deposit semiconducting materials layer by layer directly into tiny holes in optical fibers. This bypasses the need to integrate fiber-optics onto a chip, and means that the data signal never has to leave the fiber."

astroengine writes "It's a strange irony that to afford the expense of space exploration, international collaboration is often sought after — spreading the cost across several international partners means the biggest space missions may be accomplished. And yet in times of austerity, national budgets balk at the prospect of investing in international projects like ExoMars. Sadly, that's exactly what could be facing the ambitious ESA-led Mars rover/satellite mission if NASA's Science Mission Directorate budget is slashed in the next financial year. NASA may pull out of the project, leaving ExoMars with no rockets or a means to actually land on Mars. Could Russia help out? Possibly, but it will still lead to ESA taking on more cost than it has budgeted for."

jfruh writes "In an email exchange with privacy blogger Dan Tynan, Columbia law professor Eben Moglen referred to Facebook as a 'man in the middle attack' — that is, a service that intercepts communication between two parties and uses it for its own nefarious purposes. He said, 'The point is that by sharing with our actual friends through a web intermediary who can store and mine everything, we harm people by destroying their privacy for them. It's not the sharing that's bad, it's the technological design of giving it all to someone in the middle. That is at once outstandingly stupid and overwhelmingly dangerous.' Tynan is a critic of Facebook, but he thinks Moglen is overstating the case."

Hugh Pickens writes "Space.com reports that an online petition directed at the USPS and its Citizen Stamp Advisory Committee (CSAC) hopes to collect 100,000 signatures or more by March 13, the 82nd anniversary of the announcement of Pluto's discovery as the New Horizons robotic spacecraft gets closer to flyby Pluto and its moons in 2015. 'This is a chance for us all to celebrate what American space exploration can achieve though hard work, technical excellence, the spirit of scientific inquiry, and the uniquely human drive to explore,' reads the petition. Whether or not the New Horizons team is successful in getting the USPS to honor their spacecraft's mission, the probe will have delivered a stamp to Pluto. New Horizons includes nine stowaways including one of the 1991 'Not Yet Explored' Pluto stamps together with other mementos including a Florida quarter, a small container with an ounce of the ashes of Clyde Tombaugh, discoverer of Pluto, and a small segment of 2004 Ansari X Prize winner SpaceShipOne, the first privately-funded crewed spacecraft. 'Why nine mementos? I bet you can guess,' says Dr. Alan Stern, New Horizons' Principal Investigator adding why he wanted to send one of the Pluto stamps on the mission. 'Pluto may not have been explored when that stamp set came out, but we were going to conquer that,' says Stern. 'I wanted to fly it as a sort of 'in your face' thing.'"

An anonymous reader writes "'Some people remember Sealab as being a classified program, but it was trying not to be,' says Ben Hellwarth, author of the new book Sealab: America's Forgotten Quest to Live and Work on the Ocean Floor, which aims to 'bring some long overdue attention to the marine version of the space program.' In the 1960s, the media largely ignored the efforts of America's aquanauts, who revolutionized deep-sea diving and paved the way for the underwater construction work being done today on offshore oil platforms. It didn't help that the public didn't understand the challenges of saturation diving; in a comical exchange a telephone operator initially refuses to connect a call between President Johnson and Aquanaut Scott Carpenter, (who sounded like a cartoon character, thanks to the helium atmosphere in his pressurized living quarters). But in spite of being remembered as a failure, the final incarnation of Sealab did provide cover for a very successful Cold War spy program."

wiredmikey writes "A hacker who tried to land an IT job at Marriott by hacking into the company's computer systems, and then unwisely extorting the company into hiring him, has been sentenced to 30 months in prison. The hacker started his malicious quest to land a job at Marriott by sending an email to Marriott containing documents taken after hacking into Marriott servers to prove his claim. He then threatened to reveal confidential information he obtained if Marriott did not give him a job in the company's IT department. He was granted a job interview, but little did he know, Marriott worked with the U.S. Secret Service to create a fictitious Marriott employee for use by the Secret Service in an undercover operation to communicate with the hacker. He then was flown in for a face-to-face 'interview' where he admitted more and shared details of how he hacked in. He was then arrested and he pleaded guilty back in November 2011. Marriott claims the incident cost the company between $400,000 and $1 million in salaries, consultant expenses and other costs."
