New submitter BiancaM (3582365) writes "A group of chemists has shown the
power of nanoparticles for closing and healing surgical wounds. Using no more than a paintbrush they are able to close surgical openings as well as classical techniques such as sutures. However in fragile deep tissues such as liver even more remarkable results were found- normally fatal damage to internal organs is repaired in seconds using a nanoparticle glue. The results show that closing after surgery can be faster and simpler using nanomaterials to glue wounds shut."
For something between the above linked abstract and the research paper, there's this write-up at PhysOrg, and a video of the technique in action.
As the San Francisco Chronicle reports, "People who have accounts on the enrollment website for President Barack Obama's signature health care law are being told to change their passwords following an administration-wide review of the government's vulnerability to the confounding Heartbleed Internet security flaw." Take note, though; the article goes on to immediately point out this does not mean that the HealthCare.gov site has been compromised: "Senior administration officials said there is no indication that the HealthCare.gov site has been compromised and the action is being taken out of an abundance of caution. The government's Heartbleed review is ongoing, the officials said, and users of other websites may also be told to change their passwords in the coming days, including those with accounts on the popular WhiteHouse.gov petitions page."Also at The Verge
First time accepted submitter turkeydance (1266624) writes "The dark web just got a little less dark with the launch of a new search engine that lets you easily find illicit drugs and other contraband online. Grams, which launched last week and is patterned after Google, is accessible only through the Tor anonymizing browser (the address for Grams is: grams7enufi7jmdl.onion) but fills a niche for anyone seeking quick access to sites selling drugs, guns, stolen credit card numbers, counterfeit cash and fake IDs — sites that previously only could be found by users who knew the exact URL for the site."
Three former astronauts — Ed Lu, Tom Jones, and Bill Anders — say that reassuring figures about the rarity of asteroid collisions with Earth are perhaps too reassuring. The B612 Foundation, of which Lu is a director, has been established to draw public awareness to the risks of a large asteroid hitting a population center -- which these three men say is a far more serious public danger than has been acknowledged by NASA and other agencies. And beyond awareness, the Foundation's immediate goal is to raise money to " design and build an asteroid-finding space telescope and launch it by 2017," and then, Armageddon-style, to follow that up with technology to divert any asteroids whose path would threaten earth.
Gud (78635) points to this story in the Washington Post about students
having trouble with paying for both food and school. "I recall a number of these experiences from my time as grad student. I remember choosing between eating, living in bad neighborhoods, putting gas in the car, etc. Me and my fellow students still refer to ourselves as the 'starving grad students.' Today we laugh about these experiences because we all got good jobs that lifted us out of poverty, but not everyone is that fortunate. I wonder how many students are having hard time concentrating on their studies due to worrying where the next meal comes from. In the article I found the attitude of collage admins to the idea of meal plan point sharing, telling as how little they care about anything else but soak students & parents for fees and pester them later on with requests for donations. Last year I did the college tour for my first child, after reading the article, some of the comments I heard on that tour started making more sense. Like 'During exams you go to the dining hall in the morning, eat and study all day for one swipe' or 'One student is doing study on what happens when you live only on Ramen noodles!'
How common is 'food insecurity in college or high school'? What tricks can you share with current students?"
New submitter katiewilliam (3621675) writes with a story at Hardware Zone about a new feature that Google's working on for Android phones' built-in cameras: the illusion of shallow depth of field in phone snapshots, which typically err on the side of too much in focus, rather than too little. Excerpting: "The Google Research Blog [note: here's a direct link] revealed that there's quite a fair bit of algorithms running to achieve this effect; to put it in a nutshell, computer vision algorithms create a 3D model of the world based on the shots you have taken, and estimate the depth to every point in the scene."
Rambo Tribble (1273454) writes "The aficionados of beer and distilled spirits could be in for a major price-shock, if proposals by the Food and Drug Administration come to pass. Currently, breweries are allowed to sell unprocessed brewing by-products to feed farm animals. Farmers prize the nutritious, low-cost feed. But, new rules proposed by the FDA could force brewers to implement costly processing facilities or dump the by-products as waste. As one brewer put it, "Beer prices would go up for everybody to cover the cost of the equipment and installation.""
"Specifically, the attacker repeatedly sent malformed heartbeat requests to the HTTPS web server running on the VPN device, which was compiled with a vulnerable version of OpenSSL, to obtain active session tokens for currently authenticated users," Mandiant's Christopher Glyer explained. "With an active session token, the attacker successfully hijacked multiple active user sessions and convinced the VPN concentrator that he/she was legitimately authenticated."
After connecting to the VPN, the attacker attempted to move laterally and escalate his/her privileges within the victim organization, Mandiant said."
jones_supa (887896) writes "In Russia, the State Duma (lower house) on Friday ratified a 2012 agreement to write off the bulk of North Korea's debt. It said the total debt stood at $10.96 billion as of Sept. 17, 2012. Russia sees this lucrative in advancing the plans to build a gas pipe and railroad through North to South Korea. The rest of the debt, $1.09 billion, would be redeemed during the next 20 years, to be paid in equal installments every six months. The outstanding debt owed by North Korea will be managed by Russia's state development bank, Vnesheconombank. Moscow has been trying to diversify its energy sales to Asia away from Europe, which, in its turn, wants to cut its dependence on oil and gas from the erstwhile Cold War foe. Russia's state-owned top natural producer Gazprom is dreaming shipping 10 billion cubic meters of gas annually through the Koreas. Russia has written off debts to a number of impoverished Soviet-era allies, including Cuba. North Korea's struggling communist economy is just 2 percent of the size of neighboring South's."
Hugh Pickens DOT Com (2995471) writes "Joel Werner writes in Slate that when Citicorp Center was built in 1977 it was, at 59 stories, the seventh-tallest building in the world but no one figured out until after it was built that although the chief structural engineer, William LeMessurier, had properly accounted for perpendicular winds, the building was particularly vulnerable to quartering winds — in part due to cost-saving changes made to the original plan by the contractor. "According to LeMessurier, in 1978 an undergraduate architecture student contacted him with a bold claim about LeMessurier's building: that Citicorp Center could blow over in the wind," writes Werner. "LeMessurier realized that a major storm could cause a blackout and render the tuned mass damper inoperable. Without the tuned mass damper, LeMessurier calculated that a storm powerful enough to take out the building hit New York every 16 years." In other words, for every year Citicorp Center was standing, there was about a 1-in-16 chance that it would collapse." (Read on for more.)
Lasrick (2629253) writes "Victor Gilinsky and Roger J. Mattson update their story on the NUMEC affair to take into account the recent release of hundreds of classified documents that shed additional light on the story. In the 1960s, the Nuclear Materials and Equipment Corporation (NUMEC) was found to be missing about a 100 pounds of bomb-grade uranium. Based on available evidence, Gilinsky and Mattson are convinced that the material ended up in Israel nuclear bombs. The newly release documents add more to the story, and Gilinsky and Mattson are calling on President Obama to declassify the remainder of the file."
An anonymous reader writes "Not everyone can drop a few hundred dollars on a VR headset, but that doesn't mean they can't experience VR! For those with the time and a bit of handiwork skill, this DIY guide from guest writer Ohaple will show you how to make a smartphone-based VR headset for as little as $20. Along the way, you'll learn the hardware and software basics of a VR headset." This project screams for a ready-made commercial version; does anyone know of existing purpose-built headgear? As one of the comments on the linked tutorial says, Poppy seems close, but lacks an LED for tracking.
1sockchuck (826398) writes "Microsoft will invest $1.1 billion to build a massive new server farm in Iowa, not far from an existing data center in West Des Moines. The 1.2 million square foot campus will be one of the biggest in the history of the data center industry. It further enhances Iowa's status as the data center capital of the Midwest, with Google and Facebook also operating huge server farms in the state."
coondoggie (973519) writes "Call it the ultimate auto-pilot — an automated system that can help take care of all phases of aircraft flight-even perhaps helping pilots overcome system failures in-flight. The Defense Advanced Research Projects Agency (DARPA) will in May detail a new program called Aircrew Labor In-Cockpit Automation System (ALIAS) that would build upon what the agency called the considerable advances that have been made in aircraft automation systems over the past 50 years, as well as the advances made in remotely piloted aircraft automation, to help reduce pilot workload, augment mission performance and improve aircraft safety."
