Implant Translates Written Words To Braille, Right On the Retina 75

An anonymous reader writes "For the first time, blind people could read street signs with a device that translates letters into Braille and beams the results directly onto a person's eye." According to the article, "In a trial conducted on a single patient who already used the [predecessor] device, the person was able to correctly read Braille letters up to 89 percent of the time, and most of the inaccuracy appeared when the participant misread a single letter. The user was able to read one word a second."

Water Bottle Fills Itself From the Air 173

mbstone writes "The Namib Desert Beetle generates water from water vapor via its shell, which has alternating hydrophilic and hydrophobic bumps which channel water droplets into its mouth. Scientists at MIT developed a self-filling water bottle using this technology, and have announced a contest for the best design of a countertop water-from-air generator."

Could Testing Block Psychopaths From Senior Management? 422

Freshly Exhumed writes "Dr. Clive Boddy believes that increasingly fluid corporate career paths have helped psychopaths conceal their disruptive workplace behavior and ascend to previously unattainable levels of authority. Boddy points out psychopaths are primarily attracted to money, status and power, currently found in unparalleled abundance in the global banking sector. As if to prove the point, many of the world's money traders self identify as the "masters of the universe." Solution? Screening with psychological tests. Who would pay for it? The insurance industry." The tech world has plenty of company heads who've been called psychopaths, too — but would you want to actually change that?

The Science of Thanks Giving 55

Hugh Pickens writes "This is Americans' big week to give thanks. Now Russell McLendon writes that giving thanks can do wonders for the human brain according to researchers at UC Berkeley's Greater Good Science Center where scientists have developed an easy way for people to do just that and, at the same time, contribute to a national research project and maybe also improve their lives. The project is part of a $5.6 million, three-year national effort called 'Expanding the Science and Practice of Gratitude,' funded by the John Templeton Foundation. The center has gone live with, an interactive, shareable gratitude journal and has invited people in the campus community to take part in the Cal Gratitude Challenge by keeping a two-week online 'gratitude journal' and, if they choose, sharing their posts with others. Early research into the power of gratitude journals ended up proving that students who wrote down everything they were grateful for strengthened their overall resilience and became less vulnerable to everyday stresses and complaints like rashes and headaches, says Emiliana Simon-Thomas. ' wanted to make this spiral notebook very accessible, and to make the research a little more specific than it has been historically,' says Simon-Thomas. Online, anyone can take part — and potentially reap the benefits. The Cal Gratitude Challenge opened November 1 and will remain open throughout November but the project has a three-year grant and participants will be able to maintain their journals for the duration and first results from the data are expected in January. 'We affirm that there are good things in the world, gifts and benefits we've received,' writes Robert Emmons as part of the project. 'This doesn't mean that life is perfect; it doesn't ignore complaints, burdens, and hassles. But when we look at life as a whole, gratitude encourages us to identify some amount of goodness in our life.'"

Ask Slashdot: Geekiest Way To Cook a Turkey? 447

First time accepted submitter almostadnsguy writes "There seem to be a lot of ways to cook a turkey the geekiest ones are probably out of the realm of possibility for normal geeks. However, Within the limits of normal society (or outside if you wish) what is the geekiest way to do it? Do you use a special brine, cook it in an inventive way, or raise genetically modified turkeys with extra legs?"

Statistics Key To Success In Run-and-Gun Basketball 97

theodp writes "Two decades before Moneyball hit the Big Screen, Coach David Arseneault of tiny Grinnell College came up with a unique style of run-and-gun basketball that he called The System, the principles of which were subjected to statistical analysis in Keys to Success in a Run-and-Gun Basketball System, a paper for the 2011 Joint Statistical Meetings. Well, as they say, sometimes The System works. On Tuesday, biochem major Jack Taylor, just three games into his career as a Grinnell College basketball player, made national news when he poured in 138 points — yes, 138 points — in a 179-104 victory over Faith Baptist Bible College. Even LeBron and Kobe were impressed. The old NCAA Division III record of 89 was set last year by Taylor's Grinnell teammate, Griffin Lentsch. Taylor's feat also bested what was deemed to be the unbeatable overall NCAA scoring record of 113 points, set by NCAA Division II performer Clarence 'Bevo' Francis of Rio Grande in 1954."

Student Refusing RFID Badge Now Fights Expulsion Order 743

BeatTheChip writes "Lawyers representing Andrea Hernandez, a science and engineering student at John Jay High School, are fighting an expulsion notice issued a week ago for refusing to wear a Smart ID badge. To represent her, lawyers filed a preliminary court injunction, seeking legal restraints on the school. She maintains stance of refusal to wear any badge containing an RFID tag for reasons of basic privacy and conflicts with her belief system. The controversial decision for her school to adopt the NFC badges is part of the Student Locator Project, tracking attendance. Local schools started issuing the lanyard badges this fall despite parental outcry at NISD school board meetings."

Climate Contrarians Seek Leadership of House Science Committee 518

An article at Ars examines three members of the U.S. House of Representatives who are seeking chairmanship of its Committee on Space, Science, and Technology. Dana Rohrabacher (R-CA) said in an interview, "My analysis is that in the global warming debate, we won. There were a lot of scientists who were just going along with the flow on the idea that mankind was causing a change in the world's climate. I think that after 10 years of debate, we can show that that there are hundreds if not thousands of scientists who have come over to being skeptics, and I don't know anyone [who was a skeptic] who became a believer in global warming." James Sensenbrenner (R-WI) has a similar record of opposing climate change, as does Lamar Smith (R-TX). Relatedly, Phil Plait, a.k.a. The Bad Astronomer, has posted an article highlighting how U.S. Senator Marco Rubio (R-FL), a member of the Senate's Commerce, Science and Transportation Committee, has declined to answer a question about how old the Earth is, calling it "one of the great mysteries."

Quantum Cryptography Conquers Noise Problem 79

ananyo writes "Quantum-encryption systems that encode signals into a series of single photons have so far been unable to piggyback on existing telecommunications lines because they don't stand out from the millions of others in an optical fiber. But now, physicists using a technique for detecting dim light signals have transmitted a quantum key along 90 kilometers of noisy optical fiber. The feat could see quantum cryptography finally enter the mainstream. The researchers developed a detector that picks out photons only if they strike it at a precise instant, calculated on the basis of when the encoded photons were sent. The team's 'self-differentiating' detector activates for 100 picoseconds, every nanosecond. The weak charge triggered by a photon strike in this short interval would not normally stand out, but the detector measures the difference between the signal recorded during one operational cycle and the signal from the preceding cycle — when no matching photon was likely to be detected. This cancels out the background hum. Using this device, the team has transmitted a quantum key along a 90-kilometer fiber, which also carried noisy data at 1 billion bits per second in both directions — a rate typical of a telecommunications fiber."

Video Genspace: New York City's Community Biolab (Video) 29

Imagine that you are at 33 Flatbush Ave. in the Brooklyn borough of what David Letterman calls "the world's greatest city." You go to the 7th floor. Congratulations. You have found New York City's community biolab, Genspace. It's a well-equipped facility without a single mad scientist in sight. Indeed, everyone here seems as happy as the people you see in a makerspace -- which should not be surprising, since Genspace is essentially a makerspace for biologists. It is confined to non-hazardous experiments, but there is plenty going on, including ongoing projects and courses with titles like DIY Neuroscience: Controlling Behavior from the Inside. You can keep up with Genspace by following their blog. And of course, if you're in the neighborhood you should stop in. It's a welcoming environment, dedicated to the idea that science is for everyone, not just a chosen few.

What "Earth-Shaking" Discovery Has Curiosity Made on Mars? 544

Randym writes "NASA scientists have some exciting new results from one of the rover's instruments. On the one hand, they'd like to tell everybody what they found, but on the other, they have to wait because they want to make sure their results are not just some fluke or error in their instrument. The exciting results are coming from an instrument in the rover called SAM. 'We're getting data from SAM as we sit here and speak, and the data looks really interesting,' says John Grotzinger. He's the principal investigator for the rover mission. SAM (Sample Analysis at Mars) is a suite of instruments onboard NASA's Mars Science Laboratory rover, Curiosity. Grotzinger says they recently put a soil sample in SAM, and the analysis shows something Earth-shaking. 'This data is gonna be one for the history books. It's looking really good,' he says."

Harvard Develops Drug-Filled, Injectable Sponge That Expands Inside the Body 24

An anonymous reader writes "Harvard bioengineers have perfected injecting us with a drug-filled sponge instead of just a liquid. It may seem strange to want to inject a piece of sponge into your body, but it does actually help solve a number of invasive problems. For example, sometimes it is necessary to have drugs released slowly into our bodies, and/or some kind of bio-scaffold is required to be positioned so that it can help support a damaged organ or to engineer new tissue. This new, injectable sponge is incredibly useful because not only can it be filled with drugs that then are slowly released, it also has a memory and can be collapsed down to a tiny fraction of its original size."

Particle Physicists Confirm Arrow of Time Using B Meson Measurements 259

ananyo writes with bad news for John Titor. From the article: "Four years after its closure, researchers working with data from the Stanford Linear Accelerator Center's particle physics experiment BaBar have used the data to make the first direct measurement confirming that time does not run the same forwards as backwards — at least for the B mesons that the experiment produced during its heyday. The application of quantum mechanics to fundamental particles rests on a symmetry known as CPT, for charge-parity-time, which states that fundamental processes remain unchanged when particles are replaced by their antimatter counterparts (C), left and right are reversed (P), and time runs in the reverse direction (T). Violations of C and P alone were first seen in radioactive decays in the 1950s, and BaBar was used to confirm violations of CP in B meson decays in 2001. To keep CPT intact, that implies that time reversal is also violated, but finding ways to compare processes running forward and backward in time has proven tricky. Theoretical physicists at the Universityof Valencia in Spain worked with researchers on BaBar to exploit the fact that the experiment had generated entangled quantum states of the meson Bzero and its antimatter counterpart Bzero-bar, which then evolved through several different decay chains. By comparing the rates of decay in chains in which one type of decay happened before another, with others in which the order was reversed, the researchers were able to compare processes that were effectively time reversed version of each other. They report in Physical Review Letters today that they see a violation of time reversal at an extremely high level of statistical significance."

Roaming Robot May Explore Mysterious Moon Caverns 29

ananyo writes "William 'Red' Whittaker often spends his Sundays lowering a robot into a recently blown up coal mine pit near his cattle ranch in Pennsylvania. By 2015, he hopes that his robot, or something like it, will be rappelling down a much deeper hole, on the Moon. The hole was discovered three years ago when Japanese researchers published images from the satellite SELENE1, but spacecraft orbiting the Moon have been unable to see into its shadowy recesses. A robot might be able to 'go where the Sun doesn't shine', and send back the first-ever look beneath the Moon's skin, Whittaker told attendees at a meeting of the NASA Innovative Advanced Concepts (NIAC) program in Hampton, Virginia, last week. And Whittaker is worth taking seriously-his robots have descended into an Alaskan volcano and helped to clean up the Three Mile Island nuclear power plant."

Global Warming On Pace For 4 Degrees: World Bank Worried 439

iONiUM writes "From the article: 'Over the years at the U.N. climate talks, the goal has been to keep future global warming below 2C. But as those talks have faltered, emissions have kept rising, and that 2C goal is now looking increasingly out of reach. Lately, the conversation has shifted toward how to deal with 3C of warming. Or 4C. Or potentially more." Overall it seems that poorer, less developed nations will be largely impacted negatively, while some countries (like Canada and Russia) will actually experience benefits. Where does that leave the rest of the 1st world countries?"

Astronomers Get Picture of Nearby Exoplanet 24

The Bad Astronomer writes "While nearly a thousand planets are known to orbit other stars, getting direct pictures of them is extremely difficult due to the glare from their host stars. Fewer than a dozen images of exoplanets exist. However, we can now add one more to the list: Kappa Andromedae b, or Kap And b for short. It's about 170 light years away, and orbits Kappa And, a massive star bright enough to see with the naked eye. One hitch: its mass puts it right at the upper limit for a planet, and it may edge into brown dwarf territory. Further observations are needed to pin its mass down."

Nanoparticles Stop Multiple Sclerosis In Mice 50

HangingChad writes "Scientists have used nanoparticles covered in proteins to trick the immune system to stop attacking myelin and halt the progression of multiple sclerosis in mice. The nanoparticles, about 200 times thinner than a human hair, are made from the same material as dissolving stitches. Scientists compare the process an immune system 'reboot'. The process keeps the immune system from treating myelin as an alien invader and to stop attacking it."

EU Working On Most Powerful Laser Ever Built 83

kkleiner writes "On the coattails of CERN's success with the Large Hadron Collider, Europeans and the world at large have another grand science project to be excited about: the Extreme Light Infrastructure project to build the most powerful laser ever constructed. These lasers will be intense enough to perform electron dynamics experiments at very short time scales or venture into relativistic optics, opening up an entirely new field of physics for study. Additionally, the lasers could be combined to generate a super laser that would shoot into space, similar to the combined laser effect of the Death Star in the Star Wars trilogy, though the goal is to study particles in space, not annihilate planets."
