coondoggie writes "The U.S. Department of Homeland Security this week issued a call for unmanned systems makers to participate in a program that will ultimately determine their safety and performance for use in first responder, law enforcement and border security situations. In a twist that will certainly raise some eyebrows, the results of the program — called the Robotic Aircraft for Public Safety (RAPS) — will remain unavailable to the public, which, considering how involved the actual public may be with these drones is unfortunate."

An anonymous reader writes in with a story about some new electronics that are designed to melt in your body not in your hand. "Scientists have created ultra-thin electronic devices that can 'melt away' in the body once their job is done. A new study published in the journal Science, details how scientists have created a tiny, fully functional electronic device capable of vanishing within their environment, like in the body or in water, once they are no longer needed or useful. There are already implants that dispense drugs or provide electrical stimulation but they do not dissolve. The latest creation is an early step in a technology that may benefit not only medicine, like enabling the development of medical implants that don't need to be surgically removed or the risk of long-term side effects, but also electronic waste disposal."
sighted writes "NASA reports that its Curiosity rover mission has found evidence that a stream once ran vigorously — and for a sustained amount of time — across the area on Mars where the rover is driving. There is, of course, earlier evidence for the presence of water on Mars, but NASA says this evidence, images of rocks containing ancient streambed gravels, is the first of its kind."
Hugh Pickens writes "Doug Gross writes that thanks to technology, there's been a recent sea change in how people today kill time. 'Those dog-eared magazines in your doctor's office are going unread. Your fellow customers in line at the deli counter are being ignored. And simply gazing around at one's surroundings? Forget about it.' With their games, music, videos, social media and texting, smartphones 'superstimulate,' a desire humans have to play when things get dull, says anthropologist Christopher Lynn and he believes that modern society may be making that desire even stronger. 'When you're habituated to constant stimulation, when you lack it, you sort of don't know what to do with yourself,' says Lynn. 'When we aren't used to having down time, it results in anxiety. 'Oh my god, I should be doing something.' And we reach for the smartphone. It's our omnipresent relief from that.' Researchers say this all makes sense. Fiddling with our phones, they say, addresses a basic human need to cure boredom by any means necessary. But they also fear that by filling almost every second of down time by peering at our phones we are missing out on the creative and potentially rewarding ways we've dealt with boredom in days past. 'Informational overload from all quarters means that there can often be very little time for personal thought, reflection, or even just 'zoning out,'" researchers write. 'With a mobile (phone) that is constantly switched on and a plethora of entertainments available to distract the naked eye, it is understandable that some people find it difficult to actually get bored in that particular fidgety, introspective kind of way.'"
coondoggie writes "The US Air Force this week said it will base the first Space Fence radar post on Kwajalein Island in the Republic of the Marshall Islands with the site planned to be operational by 2017. The Space Fence is part of the Department of Defense's effort to better track and detect space objects which can consist of thousands of pieces of space debris as well as commercial and military satellite parts."
puddingebola writes in with news of a new app that might be of interest to those studying Einstein's brain, or just looking for something neat for Halloween. "Albert Einstein's brain, that revolutionized physics, can now be downloaded as an iPad app for USD 9.99. The exclusive application, which has been just launched, promises to make detailed images of Einstein's brain more accessible to scientists than ever before. The funding to scan and digitize nearly 350 fragile and priceless slides made from slices of Einstein's brain after his death in 1955 were given to a medical museum under development in Chicago, website 'Independent.ie' reported. The application will allow researchers and novices to peer into the eccentric Nobel winner's brain as if they were looking through a microscope. 'I can't wait to find out what they'll discover,' Steve Landers, a consultant for the National Museum of Health and Medicine Chicago, who designed the app, was quoted as saying by 'Press Association.'"
DeviceGuru writes "Suitable Technologies today unveiled a telepresence robot based on technology from Willow Garage, a robotics research lab. Beam (as in 'Beam me up, Scotty' — no, really!) implements a video chat function on a computer you can remotely drive around via Internet-based control. Beam, which stands 62 inches tall and weighs 95 pounds, adheres to four operational imperatives, which are intended to mimic human interaction and behavior: reciprocity of vision (if I see you, you must see me); ensuring private communication (no recordings of what goes on); transparency of technology (keeping the interaction natural); and respect social norms (don't push or shove Beam!). But the big question is: Does Beam also adhere to Isaac Asimov's Three Laws of Robotics? Let's hope so!"
Third Position writes "The most unambiguous data to date on the elusive 113th atomic element has been obtained by researchers at the RIKEN Nishina Center for Accelerator-based Science (RNC). A chain of six consecutive alpha decays, produced in experiments at the RIKEN Radioisotope Beam Factory (RIBF), conclusively identifies the element through connections to well-known daughter nuclides. The search for superheavy elements is a difficult and painstaking process. Such elements do not occur in nature and must be produced through experiments involving nuclear reactors or particle accelerators, via processes of nuclear fusion or neutron absorption. Since the first such element was discovered in 1940, the United States, Russia and Germany have competed to synthesize more of them. Elements 93 to 103 were discovered by the Americans, elements 104 to 106 by the Russians and the Americans, elements 107 to 112 by the Germans, and the two most recently named elements, 114 and 116, by cooperative work of the Russians and Americans. With their latest findings, associate chief scientist Kosuke Morita and his team at the RNC are set follow in these footsteps and make Japan the first country in Asia to name an atomic element."
Capt.Albatross writes "A couple of months ago, the New York Times published political scientist Andrew Hacker's opinion that teaching algebra is harmful. Today, it has followed up with an article that is clearly intended to indicate the usefulness of basic mathematics by suggesting useful exercises in a variety of 'real-world' topics. While the starter questions in each topic involve formula evaluation rather than symbolic manipulation, the follow-up questions invite readers to delve more deeply. The value of mathematics education has been a (recurring issue on Slashdot)."
New mareacaspica writes with this snippet from Nature: "Researchers have constructed 3D models of two different insects, in their nymph stage by scanning their fossils with a novel technique called X-ray microtomography. They obtained sections, two centimeters long, and from the sections constructed the models. Such fossils of juvenile insects are very rare during that ancient period, and the research could provide a better understanding not only of insects, but also other animals, as the technique develops." Original Paper.
astroengine writes "A new analysis of recent observations finds evidence for a protoplanetary disk around a red dwarf star plunging in the direction of the supermassive black hole at the center of our galaxy. Ruth Murray-Clay and Avi Loeb of the Harvard-Smithsonian Center for Astrophysics did the theoretical work. Stefan Gillessen of the Max-Planck-Institute for Extraterrestrial Physics made the observations using the European Southern Observatory's Very Large Telescope. The red dwarf star will make its closest approach in the summer of 2013, hurtling only 270 billion miles from black hole. (Or roughly 54 solar system diameters, as measured from the furthest edge of the Kuiper belt.) It won't get sucked into the black hole, but it will be flung back along its elliptical orbit out to a distance of a little more than 1/10 light-years."
jamstar7 writes "From the article: 'NASA is reportedly mulling the construction of a floating Moon base that would serve as a launching site for manned missions to Mars and other destinations more distant than any humans have traveled to so far. The Orlando Sentinel reported over the weekend that the proposed outpost, called a "gateway spacecraft," would support "a small astronaut crew and function as a staging area for future missions to the moon and Mars."' This is actually a good idea, using the Moon as a staging base for exploring the cosmos. Once we build manufacturing capability there, why not build spacecraft there? We can build bigger, more spacious craft so as to not lock up future astronauts in a closet for months or years at a time." Moon base isn't quite accurate: it would be a space station at the Earth-Moon L2 Lagrange point about 60000 km from the surface of the dark side of the moon.
bdking writes "A typeface family commonly found on the devices installed in many modern cars is more likely to cause drivers to spend more time looking away from the road than an alternative typeface tested in two studies, according to new research from MIT's AgeLab." It seems that the closed letter forms of Grotesque type faces require slightly more time to read than open letter forms of Humanist type faces, just enough that it could be problematic at highway speeds.
bbianca127 writes "A study has found that fast-food logos are branded into the minds of children at an early age, perhaps fueling the U.S.'s obesity epidemic. The study showed children 60 logos from popular food brands and 60 logos from popular non-food brands. Researchers found that, when shown images of fast-food brands, the parts of kids' brains linked with pleasure and appetite lit up. This is concerning because marketers tap into those portions of the brain long before children develop self-control, and most foods marketed to kids are high in calories, sugar, sodium, and fat."
Cutting_Crew writes "Austrian skydiver Felix Baumgartner will attempt a supersonic free fall on October 8th as the worlds highest skydive. According to the Christian Science Monitor 'The current record for world's highest skydive stands at 102,800 feet (31,333 m). It was set in 1960 by U.S. Air Force Captain Joe Kittinger, who serves as an adviser for Baumgartner's mission. If Baumgartner succeeds on Oct. 8, he will break not only that mark but also the sound barrier, becoming the first skydiver ever to fall at supersonic speeds, Red Bull Stratos officials said. During the July 25 jump, Baumgartner's top freefall speed was 537 mph (864 kph) — about as fast as a commercial airliner.' Let's hope that the weather on the 8th is as good as they hope for. It would be awesome to have a real time camera feed from his helmet."
The Bad Astronomer writes "Astronomers have unveiled what may be the deepest image of the Universe ever created: the Hubble Extreme Deep Field, a 2 million second exposure that reveals galaxies over 13 billion light years away. The faintest galaxies in the images are at magnitude 31, or one-ten-billionth as bright as the faintest object your naked eye can detect. Some are seen as they were when they were only 500 million years old."
ananyo writes with great news for particle physicists and those interested in the field everywhere: "The entire field of particle physics is set to switch to open-access publishing, a milestone in the push to make research results freely available to readers. Particle physics is already a paragon of openness, with most papers posted on the preprint server arXiv. But peer-reviewed versions are still published in subscription journals, and publishers and research consortia at facilities such as the Large Hadron Collider have previously had to strike piecemeal deals to free up a few hundred articles. After six years of negotiation, the Sponsoring Consortium for Open Access Publishing in Particle Physics is now close to ensuring that nearly all particle-physics articles — about 7,000 publications last year — are made immediately free on journal websites. Upfront payments from libraries will fund the access and the contracts will be renegotiated in 2016. The idea of all this maneuvering is to minimize the hassle for the scientists themselves and ensure that every paper is open access. The alternative is the 'author pays' model, where the researchers pay to publish. But that would require all authors to comply — a difficult rule to enforce. The new deal, however, also preserves publishers' profits — for now."
fangmcgee writes "Lab-grown leather apparel could hit the runways in as little as five years—all without harming a hair on a single animal's head, according to Andras Forgacs, co-founder and CEO of Modern Meadow, a Missouri-based startup that's approaching meat-and-leather production from a tissue-bioengineering, rather than farming, point of view. Backed by Breakout Labs, the grant-awarding foundation headed by PayPal co-founder Peter Thiel, Modern Meadow seeks to combine regenerative medicine with three-dimensional printing to synthesize leather and ultimately meat."
DevotedSkeptic writes "Curiosity will be getting a software upgrade called Autonomous Exploration for Gathering Increased Science (AEGIS) which will allow it to take on the go photos to save precious time while exploring our red neighbor. Another interesting feature AGEIS may be able to provide is the ability for Curiosity to call home when it sees something interesting. It won't be a quick upgrade: AEGIS, which has been used on the Mars Exploration Rover Opportunity since 2009, will be installed on Curiosity in the next nine to 12 months, Estlin said in an interview with InformationWeek. The AEGIS software, developed by JPL, was named NASA's 'software of the year' in 2011. Opportunity uses the software to take a wide-angle image with a low-resolution camera, then picks out rocks in the image to see if there's something of interest. If so, it takes a high-resolution image using an on-board science camera that's capable of zooming in on the subject. The software has potential beyond picture taking. Its see-and-react code could be adapted to other instruments." There's a paper on the software as used in the Opportunity rover.
Hugh Pickens writes writes "BBC reports that on a robot snake that, guided by a skilled surgeon and designed to get to places doctors are unable to reach without opening a patient up, could help spot and remove tumors more effectively. Robot snakes could be as minimally invasive using body orifices or local incisions as points of entry. 'Surgery is a cornerstone treatment for cancer so new technologies making it even more precise and effective are crucial,' says Safia Danovi from Cancer Research UK. 'Thanks to research, innovations such as keyhole surgery and robotics are transforming the treatment landscape for cancer patients and this trend needs to continue.' Robot snakes could complement a robotic surgical system that has been used for the past decade — the Da Vinci surgical system — that is controlled by a surgeon sitting in a nearby chair and looking at a screen displaying the area of the body where the surgery is taking place. The surgeon manipulates the robot by pressing pedals and moving levers. Natural orifice surgery (warning: pictures of the inside of a person) has the potential to revolutionize surgery in the same way that laparoscopic surgery replaced open surgery. The objective is to enter the abdomen through an internal organ rather than through the skin — e.g. access via the mouth, esophagus and stomach, and then through the stomach wall. 'We are at the earliest stage of establishing the problems and proposing solutions,' says Rob Buckingham of OC Robotics, developer of the robot snake (video). 'Our prototype signals a direction of travel and is a milestone towards exploring a new surgical paradigm.'"
