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."
SchrodingerZ writes "The Viktor Rydberg school in Stockholm, Sweden, has announced that they have included Minecraft into the curriculum for their 13-year-old students. The program is not meant to teach children about math or language, but rather as a tool to inspire creativity in the classroom. 'They learn about city planning, environmental issues, getting things done, and even how to plan for the future,' Viktor Rydberg teacher Monica Ekman told English-language newspaper The Local. 'It's not any different from arts or woodcraft,' she added."
MassDosage writes "I first heard about the Scratch programming language a few years ago and the idea of a simple language designed to teach kids to program in a fun, new way has always appealed to me. For those of you who don't know, Scratch was developed by the wonderfully named "Lifelong Kindergarten Group" at the MIT Media Lab. It's a programming language that allows programs to be built by dragging, dropping, configuring and combining various blocks that represent common coding concepts such as if/else statements and while loops. Scratch also provides tools for doing simple animation, playing audio and controlling sprites. The idea behind it is to make programming simple, fun and accessible to first time programmers so they can understand the key concepts without first needing to learn complex syntax which can come later when they move on from Scratch to other languages. It has been very successful and there are literally millions of Scratch programs freely available from the Scratch website and many others." Read below for the rest of Mass Dosage's review.
Hugh Pickens writes "A burglar gets stuck in a chimney, a truck driver in a head on collision is thrown out the front window and lands on his feet, walks away; a wild antelope knocks a man off his bike; a candle at a wedding sets the bride's hair on fire; someone fishing off a backyard dock catches a huge man-size shark. Now Kevin Kelly writes that in former times these unlikely events would be private, known only as rumors, stories a friend of a friend told, easily doubted and not really believed but today they are on YouTube, seen by millions. 'Every minute a new impossible thing is uploaded to the internet and that improbable event becomes just one of hundreds of extraordinary events that we'll see or hear about today,' writes Kelly. 'As long as we are online — which is almost all day many days — we are illuminated by this compressed extraordinariness. It is the new normal.' But when the improbable dominates the archive to the point that it seems as if the library contains only the impossible, then the 'black swans' don't feel as improbable. 'To the uninformed, the increased prevalence of improbable events will make it easier to believe in impossible things,' concludes Kelly. 'A steady diet of coincidences makes it easy to believe they are more than just coincidences.'"
An anonymous reader writes "Three former Nortel executives accused of orchestrating a widespread multimillion-dollar fraud will learn their fate in Toronto on Monday, nearly a year after one of the largest criminal trials in Canada's corporate history began. Ontario Superior Court Justice Frank Marrocco is set to rule on whether ex-CEO Frank Dunn, ex-CFO Douglas Beatty and ex-controller Michael Gollogly manipulated financial statements at Nortel Networks Corp., between 2002-2003. The men, who each face two counts of fraud, are accused of participating in a book-cooking scheme designed to trigger $12.8 million in bonuses and stocks for themselves at the once powerful Canadian technology giant."
Google's super fast internet has turned Kansas City into an unlikely incubator for startups and tech entrepreneurs. One small neighborhood where a group is working on their ideas has been dubbed, the "Silicon Prairie." From the article: "The advantage here for startups is simple: A fast Internet pipe makes it easier to handle large files and eliminates buffering problems that plague online video, live conferencing or other network-intensive tasks. Though the Kansas City location presents challenges for startups, including the ability to raise money outside the traditional Silicon Valley venture capital scene, entrepreneurs like Synthia Payne believe it's the place to be right now for up-and-coming tech companies. Payne is one of those entrepreneurs hoping to launch her startup dream — an Internet subscription service for musicians who want to collaborate online — on the cheap. She shares the State Line Road house, known as the 'Home for Hackers,' with other startups under a deal that allows them to live rent-free while they develop their business plans."
Hugh Pickens writes "Gregg Laskoski reports in U.S. News and World Report that virtually all of the retail gasoline price volatility that Americans experienced this past year was connected to significant problems at refineries. It was those refineries' vulnerability that subjected U.S. consumers to the year's highest average price ever, $3.63 per gallon. February delivered the BP refinery fire in Cherry Point, Washington that led to gasoline price spikes all along the Pacific coast, refinery problems in the Great Lakes region pushed Chicago gas prices to an all-time high of $4.56 per gallon, and over the summer, west coast refineries incurred outages, and California saw record highs in most markets, with Los Angeles gasoline's average price peaking at $4.72/gallon in October. Finally after Reuters reported that some 7,700 gallons of fuel spilled from Phillips 66's Bayway refinery in Linden, NJ, after Hurricane Sandy, New Jersey environmental protection officials said they were not made aware of a major spill at the Bayway plant, and the refinery failed to respond to inquiries from Reuters reporters. 'Too many times, history has shown us, the Phillips 66 response or lack thereof characterizes the standard practice of the oil industry. Refineries often fail or are slow to communicate problems that create significant disruptions to fuel supplies and spikes in retail gasoline prices. More often than not, scant information is provided reluctantly, if at all,' writes Laskoski. 'When such things occur is silence from refineries acceptable? Or does our government and the electorate who put them there have a right to know what's really going on?'"
theodp writes "The e-mail that Defendant Swartz's supplemental memorandum (pdf) cites as paramount to his fifth motion to suppress [evidence against him] is relevant, but not nearly as important as he tries to make it out to be,' quipped United States Attorney Carmen M. Ortiz (pdf) in a court filing made on the same day Aaron Swartz committed suicide. In the 1-7-2011 e-mail Ortiz refers to, which was not produced for Swartz until Dec. 14th — almost two years after his 1-6-2011 arrest — a Secret Service agent reported to the Assistant U.S. Attorney that he was 'prepared to take custody anytime' of Swartz's laptop, although no one had yet sought a warrant to search the computer. In Prosecutor as Bully, Larry Lessig laments, 'They [JSTOR] declined to pursue their own action against Aaron, and they asked the government to drop its. MIT, to its great shame, was not as clear, and so the prosecutor had the excuse he needed to continue his war against the "criminal" who we who loved him knew as Aaron.' Swartz's family also had harsh words for MIT and prosecutors: 'Decisions made by officials in the Massachusetts U.S. Attorney's office and at MIT contributed to his death. The US Attorney's office pursued an exceptionally harsh array of charges, carrying potentially over 30 years in prison, to punish an alleged crime that had no victims. Meanwhile, unlike JSTOR, MIT refused to stand up for Aaron.' With MIT President Emeritus Charles M. Vest currently serving as a Trustee of JSTOR parent Ithaka as well as a Trustee of The MIT Corporation, one might have expected MIT to issue a statement similar to the let's-put-this-behind-us one JSTOR made on the Swartz case back in 2011."
An anonymous reader writes "A group of geothermal power engineers have created three reservoirs from a single well in a place where none existed previously. This is a breakthrough for Enhanced Geothermal System technology — people who need power often can't choose a spot where there happens to be a geothermal reservoir, and EGS could allow us to create them where needed. 'Last fall, engineers pumped cold water into the ground, cracking open fissures in the deep rock, a process known as hydroshearing. They then sealed one reservoir from the other using a new technology. They injected ground-up recycled plastic bottles, which plugged up the cracks in one reservoir while millions of gallons of cold water were being pumped in to create another. Then the plastic diffused, leaving behind three reservoirs. ... The U.S. Department of Energy, which is covering half the $43.8 million cost of the Newberry project, says if the initial indications hold up, the Newberry project would mark the first time in the world that multiple geothermal reservoirs have been created on purpose from a single well in a new area.'"
