sciencehabit writes "Soot is bad stuff all around, whether you're breathing it into your lungs or it's heating the atmosphere by absorbing more of the sun's energy. But a new 4-year, 232-page assessment (PDF) of soot's role in climate finds that the combustion product could be warming the world twice as much as previously thought. The study points policymakers toward the best targets for reducing climate-warming soot emissions while at the same time improving the health of billions of people."

Nerval's Lobster writes "AMD, Intel, ARM: for years, their respective CPU architectures required separate sockets, separate motherboards, and in effect, separate servers. But no longer: Facebook and the Open Compute Summit have announced a common daughtercard specification that can link virtually any processor to the motherboard. AMD, Applied Micro, Intel, and Calxeda have already embraced the new board, dubbed 'Group Hug.' Hardware designs based on the technology will reportedly appear at the show. The Group Hug card will be connected via a simple x8 PCI Express connector to the main motherboard. But Frank Frankovsky, director of hardware design and supply chain operations at Facebook, also told an audience at the Summit that, while a standard has been provided, it may be some time before the real-world appearance of servers built on the technology."
magic maverick writes "The Atlantic recently ran an 'advertorial' for the 'Church of Scientology'. During this time, they filtered comments and removed negative comments. While they have since apologized, incisive.nu has an interesting run down of what they did wrong, from both a moral and business perspective." It turns out these sponsored stories are commonplace, and a serious source of revenue: "Native ads are critical to The Atlantic’s livelihood. They are one element of digital advertising revenue, which in 2012 accounted for a striking 59 percent of the brand’s overall advertising revenue haul. Unclear just how much of the digital advertising revenue stems from sponsor content. We’re working on that."
An anonymous reader writes "Nearly one year ago, the U.S. government launched a global takedown of Megaupload.com, with arrests of the leading executives in New Zealand and the execution of search warrants in nine countries. Canada was among the list of participating countries as the action included seizure of Megaupload.com servers. Last week, a Canadian court rejected a request to send mirror-imaged copies of 32 computer servers to authorities in the U.S., indicating that a more refined order is needed. Megaupload successfully argued 'that there is an enormous volume of information on the servers and that sending mirror image copies of all of this data would be overly broad, particularly in light of the scantiness of the evidence connecting these servers to the crimes alleged by the American prosecutors.'"
judgecorp writes "Faced with the shortage of IPv4 addresses and the failure of IPv6 to take off, British ISP PlusNet is testing carrier-grade network address translation CG-NAT, where potentially all the ISP's customers could be sharing one IP address, through a gateway. The move is controversial as it could make some Internet services fail, but PlusNet says it is inevitable, and only a test at this stage." Regarding the failure of IPv6, these graphs imply otherwise.
CowboyRobot writes "In San Antonio, a judge and a precinct commissioner are proposing (PDF) a plan to create a library called BiblioTech that offers electronic media exclusively, offering patrons only e-readers and digital materials. 'BiblioTech intends to start with 100 e-readers that can be loaned out, 50 pre-loaded e-readers for children, 50 computer stations, 25 laptops and 25 tablets, with additional accommodations planned for the visually impaired.' But the economics have yet to be ironed out. 'A typical library branch might circulate 10,000 titles a month... To do that electronically would be cost-prohibitive — most libraries can't afford to supply that many patrons with e-reading devices at one time. And expecting library visitors to bring their own devices may be expecting too much.'"
New submitter mallyn points out that the state of New York has become the first state to pass a new gun control law since the school shooting at Sandy Hook Elementary last month. "Called the New York Safe Act, the law includes a tougher assault weapons ban that broadens the definition of what constitutes an assault weapon, and limits the capacity of magazines to seven bullets, down from 10. The law also requires background checks of ammunition and gun buyers, even in private sales, imposes tougher penalties for illegal gun use, a one-state check on all firearms purchases, and programs to cut gun violence in high-crime neighborhoods. ... New York's law also aims to keep guns out of the hands of those will mental illness. The law gives judges the power to require those who pose a threat to themselves or others get outpatient care. The law also requires that when a mental health professional determines a gun owner is likely to do harm, the risk must be reported and the gun removed by law enforcement." Meanwhile, the Obama Administration is expected to propose a new federal assault weapons ban later today.
New submitter kju writes "The security blog of Verizon has the story of an investigation into unauthorized VPN access from China which led to unexpected findings. Investigators found invoices from a Chinese contractor who had actually done the work of the employee, who spent the day watching cat videos and visiting eBay and Facebook. The man had Fedexed his RSA token to the contractor and paid only about 1/5th of his income for the contracting service. Because he provided clean code on time, he was noted in his performance reviews to be the best programmer in the building. According to the article, the man had similar scams running with other companies."
skade88 writes "This story should remind us all that air pollution controls are not just about addressing global warming. They also help us have cleaner air and fewer health problems resulting from smog and haze. Starting earlier this month, Beijing, China started having worse than normal air pollution issues. On January 14, 2013 the U.S. embassy's air pollution sensors in Beijing found the density of the most dangerous small air particles, PM 2.5, at 291 micrograms per cubic meter of air. The World Health Organization's guidelines for air pollution state that PM 2.5 above 25 micrograms per cubic meter of air is dangerous to a person's health. To put the problem into perspective, NASA has released two orbital photos of Beijing showing before-and-during images of the air pollution. The photo from January 4 shows parts of Beijing still visible from space. The photo from January 14 shows nothing but a huge, thick cloud of haze with no buildings visible."
ananyo writes "Back in August last year, we discussed a study reportedly showing heavy marijuana use in teenagers had been linked to a decline in IQ in later life. Now, a new analysis suggests that the study may have been flawed. Using the same data, the researchers found that they could explain the IQ drop by properly accounting for socioeconomic factors — such as individuals from poorer backgrounds being more likely to smoke cannabis as well as having reduced access to schooling."
chicksdaddy writes "The University of Michigan will be among the first to offer graduate students the opportunity to study the security of advanced medical devices. The course, EECS 598-008 'Medical Device Security' will teach graduate students in UMich's Electrical Engineering and Computer Science program 'the engineering concepts and skills for creating more trustworthy software-based medical devices ranging from pacemakers to radiation planning software to mobile medical apps.' The new course comes amid rapid change in the market for sophisticated medical devices like insulin pumps, respirators and monitoring stations, which increasingly run on versions of the same operating systems that power desktops and servers. In 2011, the U.S. Food and Drug Administration reported that software failures were the root cause of a quarter of all medical device recalls (PDF)."
ultranerdz writes "Fedora 18 has been released. Featuring a new installer UI, GNOME 3.6, Clojure, DragonEgg, KDE Plasma Workspaces 4.9, MATE Desktop, Samba 4, Secure Boot, and updated major packages versions, this is one of the most anticipated Fedora versions yet. After more than two months of slips and delays, Fedora 18 is finally here." I'm glad to see MATE becoming more widely available; it suits me, as a GNOME 2 fan but not a complete troglodyte.
Sparrowvsrevolution writes "Over the past weekend, Defense Distributed successfully 3D-printed and tested a magazine for an AR semi-automatic rifle, loading and firing 86 rounds from the 30-round clip. That homemade chunk of curved plastic holds special significance: Between 1994 and 2004, so-called 'high capacity magazines' capable of holding more than 10 bullets were banned from sale. And a new gun control bill proposed by California Senator Dianne Feinstein in the wake of recent shootings would ban those larger ammo clips again. President Obama has also voiced support for the magazine restrictions. Defense Distributed says it hopes to preempt any high capacity magazine ban by showing how impossible it has become to prevent the creation of a simple spring-loaded box in the age of cheap 3D printing. It's posted the 3D-printable magazine blueprints on its website, Defcad.org, and gun enthusiasts have already downloaded files related to the ammo holders more than 2,200 times." Update: 01/15 23:15 GMT by T : Mea culpa; please blame my flu for mistakenly letting through that headline with "clip" where it should say "magazine." I know the difference — and I don't own any clips.
Bruce Perens writes "The Codec2 project has developed FreeDV, a program to encode digital voice on two-way radio in only 1.125 KHz of bandwidth. But FCC regulations aren't up-to-speed with the challenges of software-defined radio and Open Source. A 24 page FCC filing created by Bruce Perens proposes that FCC allow all digital modulations and published digital codes on ham radio and switch to bandwidth-based regulation."
Lasrick writes "The Bulletin of the Atomic Scientists announces whether their Doomsday Clock has been moved with this open letter to President Obama, outlining progress on a number of fronts, but also detailing what still needs to be done to avoid various threats to humanity." From the article: "2012 was a year in which the problems of the world pressed forward, but too many of its citizens stood back. In the U.S. elections the focus was "the economy, stupid," with barely a word about the severe long-term trends that threaten the population's well-being to a far greater extent: climate change, the continuing menace of nuclear oblivion, and the vulnerabilities of the world's energy sources."
