The Bad Astronomer writes "On Oct. 10, 2013, the Cassini spacecraft took a series of wide-angle pictures of Saturn from well above the plane of the rings. Croatian software developer and amateur astronomical image processor Gordan Ugarkovic assembled them into a stunning mosaic (mirrored on Flickr), showing the planet from a high angle not usually seen. There's a lot to see in this image, including the rings (and the gaps therein), moons, and the planet itself, including the remnants of a monstrous northern hemisphere storm that kicked off in 2010. It's truly wondrous."

littlesparkvt writes "Earth's most eminent emissary to Mars has just proven that those rare Martian visitors that sometimes drop in on Earth — a.k.a. Martian meteorites — really are from the Red Planet. A key new measurement of Mars' atmosphere by NASA's Curiosity rover provides the most definitive evidence yet of the origins of Mars meteorites while at the same time providing a way to rule out Martian origins of other meteorites."

Daniel_Stuckey writes "If you give a mouse a cookie, you can spend all day following it around the house while it wants to do a bunch of tedious activities. Or, you can trap it in a box, keep feeding it cookies, and then make the outrageous claim that Oreos are as addictive as cocaine. Students at Connecticut College opted for the second option, and the consequences that ensued were much more annoying than making some arts and crafts with a darn mouse. Fox News reported that a 'College study finds Oreo cookies are as addictive as drugs,' Forbes explained 'Why Your Brain Treats Oreos Like a Drug,' and a ton of other sites ran with the story as well. Here's how the experiment, which has not been peer reviewed and has not been presented yet, went down. Mice were placed in a maze, with one end holding an Oreo and the other end holding a rice cake. The mice, without fail, decided to eat the Oreo over the rice cake, proving once and for all that mice like cookies better than tasteless discs with a styrofoamy texture."

the_newsbeagle writes "About four million people around the world have pacemakers implanted in their bodies, and those devices all got there the same way: surgeons sliced open their patients' shoulders and inserted the pulse-generating devices in the flesh near the heart, then attached tiny wires to the heart muscle. ... A device that just received approval in the EU seems to solve those problems. This tiny pacemaker is the first that doesn't require wires to bring the electrical signal to the heart muscle, because it's implanted inside the heart itself, and is hooked onto the inner wall of one of the heart's chambers. This is possible because the cylindrical device can be inserted and attached using a steerable catheter that's snaked up through the femoral artery."

MancunianMaskMan writes "The BBC writes about the meteorite that fell from the sky 8 months ago: 'The object plunged into Lake Chebarkul in central Russia on 15 February, leaving a 6m-wide hole in the ice. Scientists say that it is the largest fragment of the meteorite yet found.'" This is one of the ten largest meteorite fragments ever recovered. Unfortunately, it broke into three pieces after being lifted from the lake, and managed to destroy the scale used to weigh it when it hit 570kg.

ananyo writes "Jurassic Park's iconic image of a fossilized blood-filled mosquito was thought to be fiction — until now. For the first time, researchers have identified a fossil of a female mosquito with traces of blood in its engorged abdomen. The fossilized mosquito contains molecules that provide strong evidence of blood-feeding among ancient insects back to 46 million years ago (paper abstract). The insect was found not in amber, as depicted in Jurassic Park, but in shale sediments from Montana. After 46 million years, however, any DNA would be long degraded."

astroengine writes "For the first time, astronomers have discovered a sun-like star playing host to a 'habitable zone' exoplanet located inside the Milky Way's galactic bulge — some 25,000 light-years distant — using a quirk of Einstein's general relativity. But don't go having dreams of exotic getaways to the glistening lights of the center of our galaxy; this exoplanet is a huge gas giant world, about five times the mass of Jupiter. However, there is something (potentially) very exciting about this new discovery. Like Jupiter, this newly discovered giant exoplanet may possess small satellites; exomoons that could have life-giving potential. 'Indeed, although the data do not explicitly show any signature of a companion to the Jupiter planet, this possibility is not ruled out,' the researchers write [arXiv]. 'The planet is apparently at the edge between the snow line and the habitable zone, but considering a potential greenhouse warming effect, the surface temperature of a possible companion (exomoon) can be suitable for habitability.'"

dryriver sends this BBC report: "The European Space Agency has unveiled plans to 'take 3D printing into the metal age' by building parts for jets, spacecraft and fusion projects. The Amaze project brings together 28 institutions to develop new metal components which are lighter, stronger and cheaper than conventional parts. Additive manufacturing (or '3D printing') has already revolutionized the design of plastic products. Printing metal parts for rockets and planes would cut waste and save money. The layered method of assembly also allows intricate designs — geometries which are impossible to achieve with conventional metal casting. Parts for cars and satellites can be optimized to be lighter and — simultaneously — incredibly robust. Tungsten alloy components that can withstand temperatures of 3,000C were unveiled at Amaze's launch on Tuesday at London Science Museum. At such extreme temperatures they can survive inside nuclear fusion reactors and on the nozzles of rockets. 'We want to build the best quality metal products ever made. Objects you can't possibly manufacture any other way,' said David Jarvis, ESA's head of new materials and energy research."

Zothecula writes "On October 8, three teams in various parts of the world participated in an unprecedented simultaneous test of three experimental spacesuits. Coordinated from a mission control center in Innsbruck, Austria run by the Austrian Space Forum (OeWF), World Space Walk 2013 aims at setting standards for developing suits for the future exploration of the planet Mars."

realized writes "The Obamacare website Healthcare.gov has a hidden terms of service that is not shown to people when they sign up. The hidden terms, only viewable if you 'view source' on the site, says that the user has 'no reasonable expectation of privacy regarding any communication or data transiting or stored on this information system.' Sadly, the taxpayer-funded website still does not work for most people, so it's hard to confirm – though when it's fixed in two months, we should finally be able to see it." Note: As the article points out, that phrasing is "not visible to users and obviously not intended as part of the terms and conditions." So users shouldn't worry that they've actually, accidentally agreed to any terms more onerous than the ones they can read on the signup page, but it's an interesting inclusion. What's the last EULA you read thoroughly?

Okian Warrior writes "As a followup to Linus's opinion about people skeptical of the Linux random number generator, a new paper analyzes the robustness of /dev/urandom and /dev/random . From the paper: 'From a practical side, we also give a precise assessment of the security of the two Linux PRNGs, /dev/random and /dev/urandom. In particular, we show several attacks proving that these PRNGs are not robust according to our definition, and do not accumulate entropy properly. These attacks are due to the vulnerabilities of the entropy estimator and the internal mixing function of the Linux PRNGs. These attacks against the Linux PRNG show that it does not satisfy the "robustness" notion of security, but it remains unclear if these attacks lead to actual exploitable vulnerabilities in practice.'" Of course, you might not even be able to trust hardware RNGs. Rather than simply proving that the Linux PRNGs are not robust thanks to their run-time entropy estimator, the authors provide a new property for proving the robustness of the entropy accumulation stage of a PRNG, and offer an alternative PRNG model and proof that is both robust and more efficient than the current Linux PRNGs.

MarkWhittington writes "Alan Steinberg, a post doctorate fellow in political science at Sam Houston State University, conducted a study surrounding the vexing problem of how to motivate more people to support increased levels of funding for NASA. In an October 14, 2013 piece in The Space Review, Steinberg announced the results of a study conducted with a group of college students. Steinberg's approach was based on the findings of a study by Roger Launius conducted in the late 1990s that suggested that the American public believe that NASA spending takes up about 20 percent of the federal budget. It has in fact never exceeded four percent, which it enjoyed at the height of the Apollo program, and is currently about .5 percent. Steinberg was testing a notion advanced by Neil deGrasse Tyson that if people knew the true size of NASA's budget they would be more likely to support increasing it."

Lasrick writes "Roberto Bissio has an excellent piece in a roundtable on biomass energy, pointing out that small scale biomass energy projects designed for people in poor countries aren't really a solution to climate change. After pointing out that patent protections could impede wide-spread adoption, Bissio adds that the people in these countries aren't really contributing to climate change in the first place: 'Why? Because poor people, whose carbon emissions these technologies would reduce, produce very little carbon in the first place. As I mentioned in Round One, the planet's poorest 1 billion people are responsible for only 3 percent of global carbon emissions. The 1.26 billion people whose countries belong to the Organization for Economic Co-operation and Development account for 42 percent of emissions. The rich, if they reduced their emissions by just 8 percent, could achieve more climate mitigation than the poor could achieve by reducing their emissions to zero. The rich could manage this 8 percent reduction by altering their lifestyles in barely noticeable ways. For the poor, a reduction of 100 percent would imply permanent misery.'"

dryriver writes in with a story lamenting the lack of accurate science in movies. "The relationship between science and science fiction has always been tempestuous. Gravity focuses on two astronauts stranded in space after the destruction of their space shuttle. Since Gravity's US release (it comes to the UK in November) many critics have praised the film for its scientific accuracy. But noted astrophysicist Dr Neil deGrasse Tyson, director of the Hayden Planetarium at the American Museum of Natural History in New York, had several issues with the accuracy of Gravity's portrayal of space. Through a series of posts on Twitter, Tyson — who later emphasized that he 'enjoyed the film very much' — highlighted various errors. He noted the Hubble space telescope (orbiting at 350 miles above sea level), the International Space Station (at 250 miles), and a Chinese space station could never be in line of sight of one another. On top of that, most satellites orbit west to east, yet in the film the satellite debris was seen drifting east to west. Tyson also noted how Sandra Bullock's hair did not float freely as it would in zero-gravity. This is arguably not so much an error in physics, but a reflection of the limitations of cinematic technology to accurately portray actors in zero-gravity. That is, of course, without sending them into space for the duration of the film. The Michael Bay film Armageddon is known for its woeful number of inaccuracies, from the space shuttles separating their rocket boosters and fuel tanks in close proximity to each other (risking a collision) and to objects falling on to the asteroid under a gravitational pull seemingly as strong as the Earth's. More than one interested observer tried to work out how big the bomb would have to be to blow up an asteroid in the way demanded in the movie. Answer: Very big indeed. Nasa is reported to have even used Armageddon as part of a test within their training program, asking candidates to identify all the scientific impossibilities within the film."

Nerval's Lobster writes "In theory, the federal government's Health Insurance Marketplace was supposed to make things easy for anyone in the market for health insurance. But fourteen days after the Website made its debut, the online initiative—an integral part of the Obama administration's Affordable Care Act—has metastasized into a disaster. Despite costing $400 million (so far) and employing an army of experienced IT contractors (such as Booz Allen Hamilton and CGI Group), the Website is prone to glitches and frequent crashes, frustrating many of those seeking to sign up for a health-insurance policy. Unless you're the head of a major federal agency or a huge company launching an online initiative targeted at millions of users, it's unlikely you'll be the one responsible for a project (and problems) on the scale of the Health Insurance Marketplace. Nonetheless, the debacle offers some handy lessons in project management for Websites and portals of any size: know your IT specifications (federal contractors reportedly didn't receive theirs until a few months ago), choose management capable of recognizing the problems that arise (management of Healthcare.gov was entrusted to the Medicare and Medicaid agency, which didn't have the technical chops), roll out small if possible, and test, test, test. The Health Insurance Marketplace fiasco speaks to an unfortunate truth about Web development: even when an entity (whether public or private, corporation or federal government) has keen minds and millions of dollars at its disposal, forgetting or mishandling the basics of successful Web construction can lead to embarrassing problems."

mdsolar writes in with a story about evidence of a comet explosion over Egypt 28 million years ago. "Saharan glass and a brooch belonging to King Tut provide the first evidence of a comet directly impacting Earth, a new study claims. The finding may help unlock some of the mysteries surrounding the birth of our solar system. About 28 million years ago a comet exploded over Egypt, creating a 3600F (2000C) blast wave that spread out over the desert below. The fiery shockwave melted the sand, forming copious amounts of yellow silica glass scattered over 2,300 square miles (6,000 square kilometers) of the Sahara. Polished into the shape of a scarab beetle, a large piece of this glass found its way into a brooch owned by the famed Egyptian boy king Tutankhamen. 'Because there is no sign of an impact crater, it has been a mystery as to what kind of celestial event actually could have caused this debris field, but a small, black stone found lying in the middle of the glass area caught our attention,' said study co-author David Block, an astronomer at Wits University in Johannesburg, South Africa."

rnws writes "The BBC reports that an English High Court judge has ruled that sisters aged 15 and 11 must have the MMR vaccine even though they and their mother do not want it. The High Court decision, made last month, came after the girls' father brought a case seeking vaccination. When outlining her decision in the latest case, Mrs Justice Theis emphasized it was a specific case 'only concerned with the welfare needs of these children', but lawyers say as one of a series it confirms there is no longer any debate about the benefits of the vaccine."

An anonymous reader writes "It looks like nobody is quite sure how long it will take to fix the health insurance marketplace website. '"One person familiar with the system's development said that the project was now roughly 70 percent of the way toward operating properly, but that predictions varied on when the remaining 30 percent would be done," the Times reported yesterday. "'I've heard as little as two weeks or as much as a couple of months,' that person said. Others warned that the fixes themselves were creating new problems, and said that the full extent of the problems might not be known because so many consumers had been stymied at the first step in the application process."'"

An anonymous reader writes "A citizens' group in Tokyo claims to have found elevated levels of radioactivity at 39 sporting venues earmarked for the 2020 Olympic Games. Expert and organizers are cautious about the findings but see no problem, as the levels do not pose an immediate threat to human health. From the article: '"It is difficult to have this debate unless we know for sure whether this radiation is from Fukushima or whether it is naturally occurring background radiation," said Pieter Franken, founder of the Japan office of the environmental monitoring organization Safecast."

mattydread23 writes "Often, the signs of eventual heart failure are there, but they consist of a lot of weak signals over a long period of time, and doctors are not trained to look for these patterns. IBM and a couple heathcare providers, Sutter Health and Geisinger Health System, just got a $2 million grant from NIH to figure out how better data analysis can help prevent heart attack. But the trick is that doctors will have to use electronic records — it also means a lot more tests. Andy Patrizio writes, 'What this means is doctors are going to have to expand the tests they do and the amount of data they keep. Otherwise, the data isn't so Big.'"
