$42,000 Prosthetic Hand Outperformed By $50 3D Printed Hand

An anonymous reader writes "A man named Jose Delgado was so used to using a $42,000 myoelectric prosthetic hand for the last year that he didn't realize that there were other options out there. Although Delgado, born without a left hand, was able to obtain the hand via his insurance, he found that a 3D printed 'Cyborg Beast,' open source hand ,which costs just $50 to print, actually was more comfortable and performed better than the device which costs 840 times as much money."

Biofuels From Corn Can Create More Greenhouse Gases Than Gasoline

New submitter Chipmunk100 (3619141) writes "Using corn crop residue to make ethanol and other biofuels reduces soil carbon and can generate more greenhouse gases than gasoline, according to a study published today in the journal Nature Climate Change. The findings by a University of Nebraska-Lincoln team of researchers cast doubt on whether corn residue can be used to meet federal mandates to ramp up ethanol production and reduce greenhouse gas emissions."

L.A. Science Teacher Suspended Over Student Science Fair Projects

An anonymous reader writes "A high school science teacher at Grand Arts High School in Los Angeles was suspended from the classroom in February, after two of his science fair students turned in projects deemed dangerous by the administrators. "One project was a marshmallow shooter — which uses air pressure to launch projectiles. The other was an AA battery-powered coil gun — which uses electromagnetism to launch small objects. Similar projects have been honored in past LA County Science Fairs and even demonstrated at the White House."

Why Portland Should Have Kept Its Water, Urine and All

Ars Technica has nothing good to say about the scientific understanding (or at least public understanding) that led Portland to drain 38 million gallons of water after a teenage prankster urinated into the city's water supply. Maybe SCADA systems shouldn't be quite as high on the list of dangers, when major utilities can be quite this brittle even without a high-skill attack.

SpaceX Successfully Delivers Supplies To ISS

Reuters reports on the successful SpaceX-carried resupply mission to the ISS: "A cargo ship owned by Space Exploration Technologies arrived at the International Space Station on Sunday, with a delivery of supplies and science experiments for the crew and a pair of legs for the experimental humanoid robot aboard that one day may be used in a spacewalk. Station commander Koichi Wakata used the outpost's 58-foot (18-meter) robotic crane to snare the Dragon capsule from orbit at 7:14 a.m. (1114 GMT), ending its 36-hour journey. ... "The Easter Dragon is knocking at the door," astronaut Randy Bresnik radioed to the crew from Mission Control in Houston. Space Exploration, known as SpaceX, had planned to launch its Dragon cargo ship in March, but was delayed by technical problems, including a two-week hold to replace a damaged U.S. Air Force radar tracking system."

Ask Slashdot: Professional Journaling/Notes Software?

netdicted writes "At the very outset of my career the importance of keeping a daily journal of activities and notes was clearly evident. Over the years I've always had a college ruled composition notebook nearby to jot down important ideas, instructions, tasks, etc. Putting away the rock and chisel was not optional when the volumes grew beyond my mental capacity to successfully index the contents. Over the years I've tried countless apps to keep a digital journal and failed miserably.

In my mind the ideal app or solution is a single file or cloud app where I can organize personal notes on projects, configurations, insights, ideas, etc., as well as noting major activities or occurrences of the day. My original journals saved me on a number of occasions. Unfortunately my tenacity for keeping one has suffered from a fruitless search for a suitable solution. Currently I'm experimenting with Evernote and Tiddlywiki. They approach the problem from two different angles. What do you use?"

Google Aids Scientology-Linked Group CCHR With Pay-Per-Click Ads

An anonymous reader writes "The Citizens Commission on Human Rights (CCHR), a Scientology front group, has received a 'grant from Google in the amount of $10,000 per month worth of Pay Per Click Advertising to be used in our Orange County anti-psych campaigns.' CCHR believes that ALL psychiatrists are evil. They believe that psychiatrists were behind the holocaust, and these shadow men were never brought to justice. CCHR also believes that psychiatrists were behind the 911 attacks. Scientologists believe that psychiatrists have always been evil, and their treachery goes back 75 million years when the psychiatrists assisted XENU in killing countless alien life forms. Thanks Google! We may be able to stop these evil Psychs once and for all!"

Cody Wilson Interview at Reason: Happiness Is a 3D Printed Gun

An anonymous reader writes "Cody Wilson details his conflict with the State Department over 3-D printable guns in this new interview with ReasonTV. In this video, he discusses how 3-D printing will render gun control laws obsolete and unenforceable; why Dark Wallet, his new crypto-currency, is much more subversive than Bitcoin; his legal defense, headed by Alan Gura (attorney in District of Columbia v. Heller and McDonald v. Chicago); and his forthcoming book about anarchy and the future."

Google and Facebook: Unelected Superpowers?

theodp (442580) writes "'The government is not the only American power whose motivations need to be rigourously examined,' writes The Telegraph's Katherine Rushton. 'Some 2,400 miles away from Washington, in Silicon Valley, Google is aggressively gaining power with little to keep it in check. It has cosied up to governments around the world so effectively that its chairman, Eric Schmidt, is a White House advisor. In Britain, its executives meet with ministers more than almost any other corporation. Google can't be blamed for this: one of its jobs is to lobby for laws that benefit its shareholders, but it is up to governments to push back. As things stand, Google — and to a lesser extent, Facebook — are in danger of becoming the architects of the law.' Schmidt, by the way, is apparently interested in influencing at least two current hot-button White House issues. Joined by execs from Apple, Oracle, and Facebook, the Google Chairman asserted in a March letter to Secretary of State John Kerry that the proposed Keystone XL pipeline is not in the economic interests of the U.S.; the Obama administration on Friday extended the review period on the pipeline, perhaps until after the Nov. 4 congressional elections. And as a 'Major Contributor' to Mark Zuckerberg's FWD.us PAC, Schmidt is also helping to shape public opinion on the White House's call for immigration reform; FWD.us just launched new attack ads (videos) and a petition aimed at immigration reform opponent Rep. Steve King. In Dave Eggers' The Circle, politicians who impede the company execs' agenda are immediately brought down. But that's fiction, right?"

Why Tesla Really Needs a Gigafactory

timothy posted 9 hours ago | from the if-only-there-were-fast-swap-stations-everywhere dept.

153

Hodejo1 (1252120) writes "Tesla has already put over 25,000 cars on the road with more to come and, presumably, most will still be running well past the 8-year battery warranty. What would happen if it is time to replace the battery pack on an old Model S or X and the cost is $25K? Simple, it would destroy the resale value of said cars, which would negatively affect the lease value of new Tesla automobiles. That's a big part of the real reason why Tesla is building its own battery factory. They not only need to ensure enough supply for new cars, but they have to dramatically bring down the price of the replacement batteries low enough so owners of otherwise perfectly running old Teslas don't just junk them. The Tesla Roadster was not a mass produced vehicle, so the cost of replacing its battery is $40K. The economies of scale of a gigafactory alone will drop battery costs dramatically. Heavy research could drop it further over the next decade or so."

LADEE Probe Ends Its Mission On the Far Side Of the Moon

The mission of NASA's LADEE probe was brought to an intentional violent end yesterday, when it smashed into the far side of the moon. As the Ars Technica report explains, "NASA's policy is to treat the locations of the Moon landings as historical sites, and it takes pains to preserve them from possible damage. LADEE didn't have the fuel to control its orbit indefinitely. As a result, the controllers had been preparing to terminate the probe for several weeks. ... The exact moment of impact isn't clear, since the precise terrain it hit couldn't be determined in advance. (If it hit a ridge, it would have happened earlier than if LADEE plowed across a plain. What is clear is that the impact destroyed the probe." Before the end of LADEE's mission, besides close up observations, the craft was used to test a new laser-based communication system.

Obama Delays Decision On Keystone Pipeline Yet Again

timothy posted 11 hours ago | from the you-can't-divorce-politics-from-government dept.

Hugh Pickens DOT Com (2995471) writes "The Christian Science Monitor reports that once again, the Obama administration has pushed back a final decision on the controversial Keystone XL pipeline possibly delaying the final determination until after the November midterm elections. In announcing the delay, the State Department cited a Nebraska Supreme Court case that could affect the route of the pipeline that may not be decided until next year, as well as additional time needed to review 2.5 million public comments on the project. Both supporters and opponents of the pipeline criticized the delay as a political ploy. Democratic incumbents from oil-rich states have urged President Obama to approve the pipeline but approving the pipeline before the election could staunch the flow of money from liberal donors and fund-raisers who oppose the project. The Senate Republican leader, Mitch McConnell said in a statement that "at a time of high unemployment in the Obama economy, it's a shame that the administration has delayed the construction of the Keystone XL pipeline for years." Activists say its construction could devastate the environment, but several State Department reviews have concluded that the pipeline would be safe and was unlikely to significantly increase the rate of carbon pollution in the atmosphere. Even if the pipeline was canceled, it said, the oil sands crude was likely to be extracted and brought to market by other means, such as rail, and then processed and burned."

New submitter CrAlt (3208) writes with this news snipped from BSD news stalwart undeadly.org: "After the news of heartbleed broke early last week, the OpenBSD team dove in and started axing it up into shape. Leading this effort are Ted Unangst (tedu@) and Miod Vallat (miod@), who are head-to-head on a pure commit count basis with both having around 50 commits in this part of the tree in the week since Ted's first commit in this area. They are followed closely by Joel Sing (jsing@) who is systematically going through every nook and cranny and applying some basic KNF. Next in line are Theo de Raadt (deraadt@) and Bob Beck (beck@) who've been both doing a lot of cleanup, ripping out weird layers of abstraction for standard system or library calls. ... All combined, there've been over 250 commits cleaning up OpenSSL. In one week.'" You can check out the stats, in progress.

RIP, NASA Moon Landing Engineer John C. Houbolt

timothy posted yesterday | from the why-when-he-was-a-boy dept.

The Houston Chronicle reports the death of John C. Houbolt, whose ideas helped guide the U.S. moon-landing programs. Houbolt died on Tuesday at the age of 95, in a nursing home in Maine. Says the Chronicle's obituary: "His efforts in the early 1960s are largely credited with convincing NASA to focus on the launch of a module carrying a crew from lunar orbit, rather than a rocket from earth or a space craft while orbiting the planet. Houbolt argued that a lunar orbit rendezvous, or lor, would not only be less mechanically and financially onerous than building a huge rocket to take man to the moon or launching a craft while orbiting the earth, but lor was the only option to meet President John F. Kennedy's challenge before the end of the decade."

Closing Surgical Incisions With a Paintbrush and Nanoparticles

timothy posted yesterday | from the when-superglue-just-feels-cheap dept.

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.

Preventative Treatment For Heartbleed On Healthcare.gov

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."

New 'Google' For the Dark Web Makes Buying Dope and Guns Easy

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."

3 Former Astronauts: Earth-Asteroid Collisions Are a Real But Preventable Danger

timothy posted yesterday | from the asteroid-survival-movies-are-great dept.

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.

Ask Slashdot: Hungry Students, How Common?

timothy posted yesterday | from the rice-beans-eggs-and-kale dept.

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?"

Google's New Camera App Simulates Shallow Depth of Field

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."
