Desktop 3D Printers Shown To Emit Hazardous Gases and Particles

1/28/2016 8:27pm
An anonymous reader writes: A new study in the journal Environmental Science & Technology by researchers at Illinois Institute of Technology and The University of Texas at Austin sheds more light on potentially harmful emissions from desktop FDM 3D printers. The researchers measured emissions of both ultrafine particles (UFPs) and volatile organic compounds (VOCs) from 5 commercially available polymer-extrusion 3D printers using up to 9 different filaments. [The researchers] found that the individual VOCs emitted in the largest quantities included caprolactam from nylon-based and imitation wood and brick filaments (ranging from ~2 to ~180 g/min), styrene from acrylonitrile butadiene styrene (ABS) and high-impact polystyrene (HIPS) filaments (ranging from ~10 to ~110 g/min), and lactide from polylactic acid (PLA) filaments (ranging from ~4 to ~5 g/min). Styrene is classified as a "possible human carcinogen" by the International Agency for Research on Cancer (IARC classification group 2B). While caprolactam is classified as "probably not carcinogenic to humans," the California Office of Environmental Health Hazard Assessment (OEHHA) maintains low acute, 8-hour, and chronic reference exposure levels (RELs) of only 50, 7, and 2.2 g per cubic meters, respectively, all of which would likely be exceeded with just one of the higher emitting printers operating in a small office.

SpaceX Successfully Tests Crew Dragon Landing Parachutes

1/28/2016 8:00pm
SpaceX successfully tested out the parachute system it plans to use to land its Crew Dragon spaceship safely back on Earth today. By using a "mass simulator," SpaceX was able to replicate the weight and shape of the spacecraft. According to NASA, "Later tests will grow progressively more realistic to simulate as much of the actual conditions and processes the system will see during an operational mission." The goal of the test was to evaluate the four main parachutes, but this test did not include the "drogue chutes" the full landing system will utilize. The aim is for the spacecraft to splash safely into the ocean carried down by parachutes to reduce its speed. Eventually, SpaceX intends for the spacecraft to land upright on solid ground by utilizing eight SuperDraco propulsion engines. SpaceX successfully landed its Falcon 9 rocket at Cape Canaveral in December. Earlier this month, a SpaceX Falcon 9 exploded upon landing on a drone ship.

Attackers Use Microsoft Office To Push BlackEnergy Malware

1/28/2016 6:49pm
itwbennett writes: Researchers at SentinelOne reverse engineered the latest variant of the BlackEnergy 3 rootkit (the same malware used in recent attacks against Ukraine's critical infrastructure) and found indicators that suggest it is being used by insiders and that it is the byproduct of a nation-sponsored campaign. 'BlackEnergy 3 exploits an Office 2013 vulnerability that was patched some time ago, so it only works if the target machine isn't patched or an employee (either deliberately or after being tricked into it) executes the malicious Excel document,' writes CSO's Steve Ragan.

Researchers Use CRISPR To Repair Genetic Defect That Causes Blindness

1/28/2016 6:27pm
hypnosec writes: In what has been claimed to be the first use of gene editing technique CRISPR for replacement of a defective gene associated with a sensory disease, researchers have repaired a genetic defect that causes blindness. The research that led to successful editing of defective genes responsible for retinitis pigmentosa (RP) – an inherited condition that causes the retina to degrade and leads to blindness in at least 1.5 million cases worldwide – was carried out using stem cells derived from a patient's tissue. Published in Scientific Reports, the study paves the way for using CRIPSR therapeutically to treat eye diseases.

The Widely Reported ISIS Encrypted Messaging App Is Not Real

1/28/2016 6:05pm
blottsie writes: Despite widespread reports to the contrary, an app created for Islamic State militants to send private encrypted messages does not exist, a week-long Daily Dot investigation found. All of the media articles on the Alrawi app showed screenshots of a different app entirely, one that is a glorified RSS reader with a totally different name. The Defense One journalist who first reported on GSG's claims about the app told the Daily Dot that he hadn't seen any version of Alrawi at all, and the subsequent reports on the app largely relied on Defense One's reporting. The Daily Dot was the first media outlet to receive, on Jan. 18, what GSG claimed was the Alrawi encryption app. The app, called "Alrawi.apk," contained no ability to send or encrypt messages. It was created using MIT's App Inventor, a plug-and-play tool meant primarily for children.

Satellite Failure Behind GPS Timing Anomaly

1/28/2016 4:39pm
Bismillah writes: The recent 13-microsecond timing anomaly was caused by a satellite failure triggering a "software issue", the USAF 50th Space Wing has confirmed. Such an error is large enough to cause navigation errors of up to 4 km. Luckily, no issues with GPS guided munition were reported. Reader donaggie03 adds a link to the official explanation from Rick Hamilton, Executive Secretariat of the Civil Global Positioning System Service Interface Committee. From Hamilton's email: Further investigation revealed an issue in the Global Positioning System ground software which only affected the time on legacy L-band signals. This change occurred when the oldest vehicle, SVN 23, was removed from the constellation. While the core navigation systems were working normally, the coordinated universal time timing signal was off by 13 microseconds which exceeded the design specifications. The issue was resolved at 6:10 a.m. MST, however global users may have experienced GPS timing issues for several hours.

Intel Gets Called Out Again For Their M.I.A. 3.0 X.Org Driver

1/28/2016 3:57pm
An anonymous reader writes: The xf86-video-intel 3.0 DDX driver has been in development the past two and a half years without seeing an official release. The last development release even of xf86-video-intel 3.0 Git was 13 months ago with the xf86-video-intel 2.99.917 release. At that time it was said by Intel's lead DDX developer, "3 months have passed, we should make one more snapshot before an imminent release." Since then, there's been no communications about a stable release of this DDX driver that makes SNA the default acceleration architecture over UXA. Over on the intel-gfx mailing list users are bringing up again the state of xf86-video-intel 3.0 and why it isn't released yet, questioning if Intel is "able to maintain its own device driver in a usable way?"

The Future of Astronomy: NASA's James Webb Space Telescope

1/28/2016 3:16pm
An anonymous reader writes: In 1990, the Hubble Space Telescope was launched and deployed, becoming the first space-based observatory. In the years since, many others have followed, covering the entire electromagnetic spectrum, but with nothing superseding Hubble over the wavelengths it covers. That will all change with the James Webb Space Telescope, currently on schedule and almost ready for its October 2018 launch date. The science instruments are all complete, the final mirrors are being inserted into the optical assembly, the sunshield (a new, innovative component) is almost complete, and then it just needs assembly and launch. When it's all said and done, JWST will be orders of magnitude greater than all the other observatories that came before, and will finally allow us to truly see the first stars, galaxies and quasars in the Universe, not limited by the obscuring neutral gas that currently blocks our view with other observatories.

Ask Slashdot: Learning Robotics Without Hardware?

1/28/2016 2:10pm
An anonymous reader writes: I live in a Third World country with a more or less open Internet access. I'm thinking of learning robotics. I can access Github and other free software repositories, and I can read or watch online tutorials in English. My only problem is that we don't really have the money to buy robotics hardware. We can afford an Arduino or Raspberry Pi board but not the mechanical attachments. So is there any chance for me to learn robotics even if I don't have the hardware? Is it possible to program a robot using pure software simulation?

Tesla Truck 'Quite Likely,' Says Elon Musk

1/28/2016 1:49pm
An anonymous reader writes with this excerpt from Boy Genius Report: If you think Tesla's plan for world domination begins with the Model S and ends with the Model 3, you're sorely mistaken. While the Model 3 is of course the mass consumer vehicle Elon Musk is betting the company on, the Tesla CEO is certainly open to developing other types of vehicles in the future. During a recent interview in Hong Kong at the StartmeupHK Festival, Musk briefly touched on the potential for Tesla to build an electric truck. "I think it is quite likely we will do a truck in the future," Musk said. "I think it's sort of a logical thing for us to do in the future." While this might appear to be outside of Tesla's wheelhouse at first glance – the Model S is a luxury sedan, after all – the amount of money to be made in trucks is immense. To wit, the three best-selling vehicles in the U.S. in both 2014 and 2015 were all pickup trucks.

12 Years Later, Warrantless Wiretaps Whistleblower Facing Misconduct Charges

1/28/2016 1:09pm
cold fjord writes: Former Justice Department attorney Thomas Tamm sparked an intense public debate about warrantless surveillance nearly a decade before Edward Snowden. Tamm tipped reporters in 2004 about the use of nonstandard warrantless procedures under the Bush administration for intercepting international phone calls and emails of Americans. New York Times reporters James Risen and Eric Lichtblau used Tamm's revelations to help them win a Pulitzer Prize. Barack Obama criticized the program and the Obama administration Justice Department announced in 2011 that it would not bring criminal charges against him. Unfortunately Tamm is now facing disciplinary hearings before the D.C. Office of Disciplinary Counsel which prosecutes the D.C. Bar's disciplinary cases. Tamm is facing ethics charges that could result is his disbarment, revoking his law license. Tamm is alleged to have "failed to refer information in his possession that persons within the Department of Justice were violating their legal obligations to higher authority within the Department" and "revealed to a newspaper reporter confidences or secrets of his client, the Department of Justice." Tamm currently resides in Maryland where he is a public defender. The effect of the D.C. case on him there is unclear. Tamm's attorney, Georgetown University law professor Michael Frisch, says the delays seen in this case are not unusual in D.C., it can take years for matters to play out. Another of Frisch's clients, who exposed the interrogation of "American Taliban" John Walker Lindh, believes the prosecution is political persecution.

30 Years Since The Challenger Disaster: Where Were You?

Martin S. writes: Thirty years ago today, NASA suffered a spaceflight tragedy that stunned the world and changed the agency forever. When I mentioned this at work most of my colleagues are too young to remember this first hand. When I heard the news, I was in a middle-school science class; our teacher walked us solemnly over to the school library, where we watched the television news. It hit especially hard because one of our other teachers had pursued the slot that was eventually filled by Christa McAuliffe.

OSINT Analysis of Militia Communications, Equipment and Frequencies

1/28/2016 11:07am
An anonymous reader writes: On January 2, 2016, the headquarters of the Malheur National Wildlife Refuge in Oregon, United States, were occupied by armed members of rump militias in one of the longest-running law enforcement standoff in American history. The Radiomasterreport blog, using publicly available information, wrote an OSINT Analysis of Militia Communications, Radio Equipment and Frequencies. The research results has astonishing conclusions: far-right patriot militas openly carrying +3000$ AR15 rifles and US military body armour also use cheap 30$ unsecure chinese Baofeng walkie talkie radios with no encryption whatsoever. Any simple ham radio operator , police scanner owner, or even some folks with a Software Defined Radio can receive those militia communications.

Tim Cook: What's Good For the US Dollar Is Bad For Apple

1/28/2016 10:25am
theodp writes: For years," Charles Erwin Wilson famously said back in the day, "I thought what was good for our country was good for General Motors, and vice versa." That was then. This is now. The Washington Post reports that a strong U.S. dollar is the biggest threat to Apple's business around the world. "The dollar has shot up about 22 percent against a trade-weighted basket of other currencies since the middle of 2014," explains Matt O'Brien. "And in Apple's case, that's meant what would have been $100 of foreign sales in September 2014 was just $85 by the end of 2015. That's not good when you get two-thirds of your revenue overseas." Apple blamed the strength of the dollar compared to other currencies for costing it $5 billion in revenue, "For perspective, that difference is the size of an average Fortune 500 company," quipped CEO Tim Cook.

Why the Calorie Is Broken

1/28/2016 9:42am
New submitter ami.one writes: Cynthia Graber and Nicola Twilley explain how we are still using a century old method for measuring the calories in our food and the calories spent in different human activities. Essentially, there is a very big difference between burning stuff in a bomb calorie-meter and the extremely complex ways our body extracts energy from food. In fact, the exact process of digestion is yet to be understood sufficiently at a micro level, and years from being replicated to any close degree. Plus, the way our bodies spend calories for a given activity is hugely different from the way a car consumer gasoline and dependent on a number of parameters — some of which are not even known currently. Therefore, balancing calories in to Calories out is not so stupidly simple as it seems to the underweight layperson . Update: 01/28 22:09 GMT by T : Sorry for the duplicate post; it was a long night.

A Crowdfunding Site To Help Pay Patients' Medical Bills

1/28/2016 9:01am
Lucas123 writes: A start-up financial services company called Someone With Group has just completed a pilot of a crowdfunding service that allows hospitals to set up campaigns to help patients pay their medical expenses. The website, which is HIPAA compliant in terms of privacy and security, allows patients facing medical debts to inform family, friends and even strangers of their need for funds versus flowers or cards. The crowdfunding service also addresses a systemic debt issue in the healthcare industry. Each year, the U.S. healthcare industry writes off $40 billion in bad debt from unpaid medical bills. "Then you consider that $6 billion is spent on cards and flowers for patients every year. Why can't we redirect that money and put it into a debit instrument restricted to medical spending only?" said Jagemann-Bane, CEO of Someone With Group. One hospital group, Pinnacle Health Systems in Harrisburg, Penn., routinely writes off $40 million to $50 million a year in unpaid medical bills from patients. The hospital set up a crowdfunding site via Someone With Group and so far has seen a couple dozen patients use it. ... After a one-year pilot of the crowdfunding service, patients who've used it on average have raised $2,315.
