sciencehabit writes "If you've pondered whether to sink a cool couple of grand into a fancy new three-dimensional TV but didn't want to mess around with those dorky glasses, you may want to sit tight for a few more years. Researchers at Hewlett Packard Laboratories in Palo Alto, California, report that they've come up with a new 3D technology that not only doesn't require viewers to wear special glasses, but it also can be viewed from a wide variety of angles. The advance could propel the development of mobile 3D devices as well as TVs."
skade88 writes "Jeff Bezos has been spending his time fishing up parts of the Apollo 11 rockets. From his blog 'What an incredible adventure. We are right now onboard the Seabed Worker headed back to Cape Canaveral after finishing three weeks at sea, working almost 3 miles below the surface. We found so much. We've seen an underwater wonderland – an incredible sculpture garden of twisted F-1 engines that tells the story of a fiery and violent end, one that serves testament to the Apollo program. We photographed many beautiful objects in situ and have now recovered many prime pieces. Each piece we bring on deck conjures for me the thousands of engineers who worked together back then to do what for all time had been thought surely impossible.'"
An anonymous reader writes "A new study released today (abstract) indicates that the Voyager 1 spacecraft has become the first man-made object to exit our solar system. Instrumentation data sent back to NASA indicate the historic event likely occurred on August 25, 2012, evidenced by drastic changes in radiation levels as the craft ventured past the heliopause. What remains to be seen, however, is whether Voyager 1 has actually made it to true interstellar space, or whether it has entered a separate, undefined region beyond our solar system. Either way, the achievement is truly monumental. 'It's outside the normal heliosphere, I would say that. We're in a new region,' said Bill Webber, professor emeritus of astronomy at New Mexico State University in Las Cruces. 'And everything we're measuring is different and exciting.'" Update: 03/20 20:44 GMT by S : Reader skade88 points out that the JPL Voyager team is not so sure: "It is the consensus of the Voyager science team that Voyager 1 has not yet left the solar system or reached interstellar space. In December 2012, the Voyager science team reported that Voyager 1 is within a new region called 'the magnetic highway' where energetic particles changed dramatically. A change in the direction of the magnetic field is the last critical indicator of reaching interstellar space and that change of direction has not yet been observed." So we'll probably be hearing about this again in a couple years.
ananyo writes "Belgian mathematician Pierre Deligne completed the work for which he became celebrated nearly four decades ago, but that fertile contribution to number theory has now earned him the Abel Prize, one of the most prestigious awards in mathematics. The prize is worth 6 million Norwegian krone (about US$1 million). In short, Deligne proved one of the four Weil conjectures (he proved the hardest; his mentor, Alexander Grothendieck, had proved the second conjecture in 1965) and went on to tools such as l-adic cohomology to extend algebraic geometry and to relate it to other areas of maths. 'To some extent, I feel that this money belongs to mathematics, not to me,' Deligne said, via webcast."
ananyo writes "Researchers have imaged an entire vertebrate brain at the level of single neurons for the first time. A team of scientists based at the Janelia Farm Research Campus in Ashburn, Virginia, were able to record activity across the whole brain of a fish embryo almost every second, detecting 80% of its 100,000 neurons. The work is a first step towards mapping the activity of a whole human brain — which contains about 85,000 times more neurons than the zebrafish brain. The imaging system relies on a genetically engineered zebrafish (Danio rerio). The fish's neurons make a protein that fluoresces in response to fluctuations in the concentration of calcium ions, which occur when nerve cells fire. A microscope sends sheets of light rather than a conventional beam through the fish's brain, and a detector captures the signals like a viewer watching a cinema screen. The system records activity from the full brain every 1.3 seconds."
MTorrice writes "When energy companies extract natural gas trapped deep underground using hydraulic fracturing, they're left with water containing high levels of pollutants, including benzene and barium. Sometimes the gas producers dispose of this fracking wastewater by sending it to treatment plants that deal with sewage and water from other industrial sources. But a new study (abstract) suggests that the plants can't handle this water's high levels of contaminants: Water flowing out of the plants into the environment still has elevated levels of the chemicals from natural gas production."
skade88 writes "Wired has a good article that covers the origins of the white dwarf super nova Johannes Kepler observed in 1604. From the article: 'Up until now, it was unclear what lead to the star's explosion. New Chandra data suggests that, at least in the case of Kepler's remnant, the white dwarf grabbed material from its companion star. The disk-shaped structure seen near the center suggests that the supernova explosion hit a ring of gas and dust that would have formed, like water circling a drain, as the white dwarf sucked material away from its neighbor. In addition, magnesium is not an element formed in great abundances during Type 1a supernovas, suggesting it came from the companion star. Whether or not Kepler's supernova is a typical case remains to be seen. '"
sciencehabit writes "Cliff swallows that build nests that dangle precariously from highway overpasses have a lower chance of becoming roadkill than in years past thanks to a shorter wingspan that lets them dodge oncoming traffic. That's the conclusion of a new study based on 3 decades of data collected on one population of the birds. The results suggest that shorter wingspan has been selected for over this time period because of the evolutionary pressure put on the population by cars."
Zothecula writes "The race to build a manned research station on the moon has been slowly picking up steam in recent years, with several developed nations actively studying a variety of construction methods. In just the past few months, the European Space Agency revealed a design involving 3D-printed structures and the Russian Federal Space Agency announced plans for a moon base by 2037. Now international design agency, Architecture Et Cetera (A-ETC), has thrown its hat into the ring with a proposal for SinterHab, a moon base consisting of bubble-like compartments coated in a protective layer of melted lunar dust."
cylonlover writes "Australian scientists have successfully revived and reactivated the genome of an extinct frog. The 'Lazarus Project' team implanted cell nuclei from tissues collected in the 1970s and kept in a conventional deep freezer for 40 years into donor eggs from a distantly-related frog. Some of the eggs spontaneously began to divide and grow to early embryo stage with tests confirming the dividing cells contained genetic material from the extinct frog. The extinct frog in question is the Rheobatrachus silus, one of only two species of gastric-brooding frogs, or Platypus frogs, native to Queensland, Australia. Both species became extinct in the mid-1980s and were unique amongst frog species for the way in which they incubated their offspring."
RocketAcademy writes "Actress/singer Sarah Brightman's trip to the International Space Station may not happen in 2015 as scheduled. Space Adventures works with the Russian Federal Space Agency (Roscosmos) to fly private citizens like Brightman on Soyuz taxi flights. Those taxi missions normally last eight days, but NASA and Roscosmos are considering a plan to extend the 2015 taxi flight to one month, so it can carry a scientist to perform some additional research aboard ISS. If that happens, Brightman will lose her seat. This situation points to the need for more flexible transportation options and new orbital facilities which are not subject to the same operational restrictions as ISS. SpaceX, Boeing, and Sierra Nevada are working on the transportation problem, while Bigelow Aerospace expects to begin launching its Space Station Alpha in 2015. So, the era of citizen astronauts visiting ISS may be drawing to a close."
An anonymous reader writes "Bigger eyes and a corresponding greater allocation of the brain to process visual information is the most recent theory about the reasons that led to the extinction of Neanderthals, our closest relatives. Neanderthals split from the primate line that gave rise to modern humans about 400,000 years ago. This group then moved to Eurasia and completely disappeared from the world about 30,000 years back. Other studies have shown that Neanderthals might have lived near the Arctic Circle around 31,000 to 34,000 years ago."
kkleiner writes "Now the field of 3D printing has advanced so far that a company called Nanoscribe is offering one of the first commercially available 3D printers for the nanoscale. Nanoscribe's machine can produce tiny 3D printed objects that are only the width of a single human hair. Amazingly this includes 3D printed objects such as spaceships, micro needles, or even the empire state building."
Physicist Chris Lee explains one of the toughest judgment calls scientists have to make: figuring out if their crazy ideas are worth pursuing. He says: "Research takes resources. I don't mean money—all right, I do mean money—but it also requires time and people and lab space and support. There is a human and physical infrastructure that I have to make use of. I may be part of a research organization, but I have no automatic right of access to any of this infrastructure. ... This also has implications for scale. A PhD student has the right to expect a project that generates a decent body of work within those four years. A project that is going to take eight years of construction work before it produces any scientific results cannot and should not be built by a PhD student. On the other hand, a project that dries up in two years is equally bad. ... the core idea also needs to be structured so, should certain experiments not work, they still build something that can lead to experiments which do work. Or, if the cool new instrument we want to build can't measure exactly what I intended, there are other things it can measure. One of those other things must be fairly certain of success. To put it bluntly: all paths must lead to results of some form."
An anonymous reader writes "The Obama Administration has put forth a proposal to collect $2 billion over the next 10 years from revenues generated by oil and gas development to fund scientific research into clean energy technologies. The administration hopes the research would help 'protect American families from spikes in gas prices and allow us to run our cars and trucks on electricity or homegrown fuels.' In a speech at Argonne National Laboratory, Obama said the private sector couldn't afford such research, which puts the onus on government to keep it going. Of course, it'll still be difficult to get everyone on board: 'The notion of funding alternative energy research with fossil fuel revenues has been endorsed in different forms by Republican politicians, including Alaskan senator Lisa Murkowsi. But the president still faces an uphill battle passing any major energy law, given how politicized programs to promote clean energy have become in the wake of high-profile failures of government-backed companies.'"
RocketAcademy writes "The Federal Communications Commission has issued a Public Notice to help commercial space companies obtain use of communications frequencies for launch, operations, and reentry. Commercial space companies can obtain the use of government frequencies on a temporary, non-interference basis through the FCC's Experimental Authorization process. Experimental Authorizations are valid for a six-month period from the date of grant and are renewable, but applicants must obtain a new authorization for each launch and must apply 90 days in advance. Unfortunately, this requirement does not meet the needs of suborbital launch providers who expect to fly several times per day and schedule launches as needed, on very short notice."
Hugh Pickens writes "The Web is a place for unlimited exchange of ideas. But according to an NPR report, researchers have found that rude comments on articles can change the way we interpret the news. 'It's a little bit like the Wild West. The trolls are winning,' says Dominique Brossard, co-author of the study on the so-called 'Nasty Effect.' Researchers worked with a science writer to construct a balanced news story on the pros and cons of nanotechnology, a topic chosen so that readers would have to make sense of a complicated issue with low familiarity. They then asked 1,183 subjects to review the blog post from a Canadian newspaper that discussed the water contamination risks of nanosilver particles and the antibacterial benefits. Half saw the story with polite comments, and the other half saw rude comments, like: 'If you don't see the benefits of using nanotechnology in these products, you're an idiot.' People that were exposed to the polite comments didn't change their views really about the issue covering the story, while the people that did see the rude comments became polarized — they became more against the technology that was covered in the story. Brossard says we need to have an anchor to make sense of complicated issues. 'And it seems that rudeness and incivility is used as a mental shortcut to make sense of those complicated issues.' Brossard says there's no quick fix for this issue (PDF), and while she thinks it's important to foster conversation through comments sections, every media organization has to figure out where to draw the line when comments get out of control. 'It's possible that the social norms in this brave new domain will change once more — with users shunning meanspirited attacks from posters hiding behind pseudonyms and cultivating civil debate instead,' writes Brossard. 'Until then, beware the nasty effect.'"
astroengine writes "Although there appears to be a mysterious dearth of exoplanets smaller than Earth, astronomers using data from NASA's Kepler space telescope have estimated that nearly a quarter of all sun-like stars in our galaxy play host to worlds 1-3 times the size of our planet. These astonishing results were discussed by Geoff Marcy, professor of astronomy at the University of California, Berkeley, during a talk the W. M. Keck Observatory 20th Anniversary Science Meeting on Thursday. '23 percent of sun-like stars have a planet within (1-2.8 Earth radii) just within Mercury's orbit,' said Marcy. 'I'll say that again, because that number really surprised me: 23 percent of sun-like stars have a nearly-Earth-sized planet orbiting in tight orbits within 0.25 AU of the host stars.'"
New submitter Spinnakker writes "Lockheed Martin, traditionally known for its development of military systems and aircraft, has developed a process for perforating graphene (carbon sheets only one atom thick) that could potentially reduce the energy required for desalination by two orders of magnitude. The process tailors the hole size to the molecules being separated. In the case of desalination, one would create holes in the graphene large enough to allow water to pass but small enough to block the salt molecules. The advantage to using graphene comes from how extremely thin the material is compared to traditional filters. The thinner the filter, the less energy is required to facilitate reverse osmosis."
ananyo writes "The research world's most famous human cell has had its genome decoded, and it's a mess. German researchers this week report the genome sequence of the HeLa cell line, which originates from a deadly cervical tumor taken from a patient named Henrietta Lacks (Slashdot has previously noted a film made about the cells and there's a recent mutli-award winning book on Lacks). Established the same year that Lacks died in 1951, HeLa cells were the first human cells to grow well in the laboratory. The cells have contributed to more than 60,000 research papers, the development of a polio vaccine in the 1950s and, most recently, an international effort to characterize the genome, known as ENCODE. The team's work shows that HeLa cells contain one extra version of most chromosomes, with up to five copies of some, and raises further questions over the widespread use of HeLa cells as models for human cell biology."
phenopticon writes "Researchers at Berkeley are attempting to revive the extinct passenger pigeon in order to set up a remote island theme park full of resurrected semi-modern extinct animals. (Well, maybe not that last part.) Quoting: 'About 1,500 passenger pigeons inhabit museum collections. They are all that's left of a species once perceived as a limitless resource. The birds were shipped in boxcars by the tons, sold as meat for 31 cents per dozen, and plucked for mattress feathers. But in a mere 25 years, the population shrank from billions to thousands as commercial hunters decimated nesting flocks. Martha, the last living bird, took her place under museum glass in 1914. ... Ben Novak doesn't believe the story should end there. The 26-year-old genetics student is convinced that new technology can bring the passenger pigeon back to life. "This whole idea that extinction is forever is just nonsense," he says. Novak spent the last five years working to decipher the bird's genes, and now he has put his graduate studies on hold to pursue a goal he'd once described in a junior high school fair presentation: de-extinction. ... Using next-generation sequencing, scientists identified the passenger pigeon's closest living relative: Patagioenas fasciata, the ubiquitous band-tailed pigeon of the American west. This was an important step. The short, mangled DNA fragments from the museums' passenger pigeons don't overlap enough for a computer to reassemble them, but the modern band-tailed pigeon genome could serve as a scaffold. Mapping passenger pigeon fragments onto the band-tailed sequence would suggest their original order."
eldavojohn writes "Just like the many stories surrounding alleged 'Wi-Fi sickness,' research is now showing that windfarm sickness spreads by word of mouth instead of applying universally to windfarms. Areas that had never had any noise or health complaints were suddenly experiencing them after 2009 when anti-wind groups targeted populations surrounding windfarms. From the article, 'Eighteen reviews of the research literature on wind turbines and health published since 2003 had all reached the broad conclusion that there was very little evidence they were directly harmful to health.' While there's unfortunately no way to prove that someone is lying about how they feel, it's likely a mixture of confirmation bias, psychosomatic response, hypochondria, greed and hatred of seeing windmills on the horizon that drives this phenomenon."
sciencehabit writes "Samples drilled from 3.5-million-year-old seafloor rocks have yielded the strongest evidence yet that a variety of microorganisms live deeply buried within the ocean's crust. These microbes make their living by consuming methane and sulfate compounds dissolved in the mineral-rich waters flowing through the immense networks of fractures in the crust. The new find confirms that the ancient lavas formed at midocean ridges and found throughout deep ocean basins are by volume the largest ecosystem on Earth, scientists say."
It's a long, slow road from tentative discovery, to various forms of peer review, to wide acceptance, never mind theory and experimental design, but recent years' work to pin down the Higgs Boson seem to be bearing fruit in the form of cautious announcements. FBeans writes with excerpts from both the New York Times ("Physicists announced Thursday they believe they have discovered the subatomic particle predicted nearly a half-century ago, which will go a long way toward explaining what gives electrons and all matter in the universe size and shape.") and from The Independent ("Cern says that confirming what type of boson the particle is could take years and that the scientists would need to return to the Large Hadron Collider — the world's largest 'atom smasher' — to carry out further tests. This will measure at what rate the particle decays and compare it with the results of predictions, as theorised by Edinburgh professor Peter Higgs 50 years ago.")

coondoggie writes "The bottom line for NASA as well as any number of government agencies in this new era of sequestration is money — and NASA in this case has too many programs chasing too few dollars. That is just one of a number of bleak conclusions NASA's Inspector General Paul Martin laid out to a Congressional hearing adding that 'declining budgets and fiscal uncertainties present the most significant external challenges to NASA's ability to successfully move forward on its many projects and programs. For the first 6 months of this year, NASA has operated under a continuing resolution that funds the Agency at last year's level of $17.8 billion. Moreover, NASA's share of the Government-wide sequestration cuts reduce that spending authority by $894 million.'"
sciencehabit writes "A fluorescent glow high in the atmosphere of Titan, Saturn's largest moon, signifies the presence of a gas that astronomers have yet to identify. The glow appears only on the daytime side of the moon at altitudes between 600 and 1250 kilometers, with the largest intensity occurring at an altitude of about 950 km. Detailed analyses reveal that the glow doesn't stem from a problem with the Saturn-orbiting Cassini craft, and it isn't associated with methane or any of the other hydrocarbons already identified as constituents of Titan's atmosphere."
An anonymous reader writes "The BBC reports on a new study of prehistoric skulls which suggests that Neanderthals became extinct because they had larger eyes than our species. As a consequence of having extra sized eyes, an average 6 millimeters larger in radius, more of their backside brain volume was devoted to seeing, at the expense of frontal lobe high-level processing of information and emotions. This difference affected their ability to innovate and socialize the way we, modern people (Homo Sapiens Sapiens) do. When the last Ice Age set on 28,000 years ago, Neanderthals had no sewn clothes and no large organized groups to rely on each other, hastening their fall. Yet, they were not stupid, brutish creatures as portrayed in Hollywood films, they were very, very smart, but not quite in the same league as the Homo Sapiens of Cromagnon."
xclr8r writes "James Holmes representation did not enter a plea today in with regards to the Aurora, Co.

The judge entered an advisory that if the plea was changed to Not Guilty by insanity that Holmes would be subject to a 'narcoanalytic interview' with the possibility of medically appropriate substances could be used e.g. so called truth serums. Holmes defense looks to have initially objected to this but as the previous article seems to infer that some compromises are being worked out. This certainly raises legal questions on how this is being played out 5th, 14th amendments. The legal expert in the second article states this is legal under Co. law but admits there's not a huge amount of cases regarding this. I was only able to find Harper v State where a defendant willingly underwent truth serum and wanted to submit the interview on his behalf but was rejected due to the judge not recognizing sufficient scientific basis to admit the evidence."
Nerval's Lobster writes "How's this for a daunting task? By 2017, IBM must develop low-power microservers that can handle 10 times the traffic of today's Internet — and resist blowing desert sands, to boot. Sound impossible? Hopefully not. Those are the design parameters of the Square Kilometer Array (SKA) Project, the world's largest radio telescope, located in South Africa and Australia amid some of the world's most rugged terrain. It will be up to the SKA-specific business unit of South Africa's National Research Foundation, IBM, and ASTON (also known as the Netherlands Institute for Radio Astronomy) to jointly design the servers. Scientists from all three organizations will collaborate remotely and at the newly established ASTRON & IBM Center for Exascale Technology in Drenthe, the Netherlands. By peering into the furthest regions of space, the SKA project hopes to glimpse 'back in time,' where the radio waves from some of the earliest moments of the universe — before stars were formed — are still detectable. The hardware is powerful enough to pick up an airport radar on a planet 50 light-years away, according to the SKA team."

From what we know now, the answer is yes.'"
Yesterday we ran the first half of Dr. Robert Bakker's essay in response to your questions. Below you'll find the second part which focuses on the history of science and religion, and the patron saint of paleontology, St. Augustine of Hippo. A big thanks goes out to Dr. Bob for his lengthy reply.

When examined by Cardiff University one of the comet samples was found to contain micro-fossils akin to plankton. NASA's Marshall Space Flight Center tested additional samples with similar results.

Update: 03/12 16:59 GMT by S : On the other hand, Phil Plait says the paper is very flawed; the sample rocks the researchers tested may not even be meteorites.

During this study, Paragon will identify major suppliers, concepts, and technologies that exist today and can be used as the baseline architecture for further development. The ECLSS will provide and maintain a safe, reliable environment for the inhabitants, providing them with clean air and water. The Mars suits will enable the settlers to work outside of the habitat and explore the surface of Mars."

The Bad Astronomer writes "Astronomers have found the third-closest star system to the Earth: called WISE 1049-5319, it's a binary brown dwarf system just 6.5 light years away. Brown dwarfs are faint, low mass objects 13 — 75 times the mass of Jupiter, and are so dim they are very difficult to detect. These newly-found nearby objects were seen in observations from 1978 but went unnoticed at the time, but since that date the large apparent motion of the binary made their proximity obvious. Only two star systems are closer: Alpha Centauri (4.3 light years) and Barnard's star (6 light years)."
A while ago you had the chance to ask paleontologist Dr. Robert Bakker a wide variety of questions. Instead of answering them individually, Dr. Bob decided to write a lengthy piece that covers most of your inquiries, and includes personal stories and some of his philosophy. The first part is a narrative about his childhood conversion to fossil studies and how his paleo-CSI approach developed. We'll post the second half, covering his training in the history of theology and how it intersects with his science, tomorrow.
sciencehabit writes "When an adult loses a tooth, there's no hope of growing a new one—unless you've got a mouse kidney handy. In a new study, researchers injected human gum tissue extracted during oral surgery into the molars of fetal mice. After giving the cells a week to get used to each other, the scientists implanted the chimeric concoction into the protective tissue surrounding the kidneys of living mice. There, 20% of the cells developed into objects recognizable as teeth, complete with the root structures missing from artificial tooth implants. The next step is to transplant these so-called 'bio-teeth' back into human mouths and see if they grow into something that we can chew on—or rather, with."

Nerval's Lobster writes "Former vice president Al Gore sat down with Wall Street Journal columnist Walt Mossberg at this year's SXSW conference to talk about the future — specifically, what Gore sees as the dangers and opportunities awaiting the planet for the next few years. Gore drilled down into what he referred to as the "stalker economy." The rise of apps such as SnapChat, which allows smartphone users to control how long friends can view messages, is emblematic of people reaching the "gag point" with pervasive recording and surveillance by government and business. "Our democracy has been hacked," Gore also told his audience, referring to the U.S. Constitution as "our operating system." While there's never been a "golden age" of American Democracy, he added, the perils emerging today are new. "If a Congressman or Senator has to spend five hours a day begging special interests or rich people for money," he said, they'll be more concerned about how what they're saying will appeal to those interests—rather than their constituents. In yet another tangent, Gore railed against genetic engineering, including Spider Goats, which are goats with spliced spider DNA that allows them to secrete spider silk along with their milk. The goats breed, extending that trait to future generations. Gore sees such things as a case of science run amok, alternately creepy and scary."

Nerval's Lobster writes "Elon Musk, CEO of SpaceX and Tesla Motors, took the keynote stage at this year's SXSW to talk about everything from space exploration to electric cars. Joining him onstage to ask questions was Chris Anderson, the former Wired editor and co-founder of 3DRobotics. Musk used his keynote discussion to show off a video of a rocket test, which he said had taken place earlier that week. In the video, a ten-story rocket takes off from a launching pad and hovers several hundred feet in the air before landing in the same spot, upright. It's an early test of SpaceX's reusable-rocket project. 'Reusability is extremely important,' Musk told the audience. 'If you think it's important that humanity extends beyond Earth and becomes a multitenant species' then reusable rockets will prove essential. Musk also talked about the recent controversy involving his Tesla Motors, which started when a New York Times reporter claimed in a much-circulated column that his electric-powered Model S sedan had ground to a halt during a test drive up the East Coast. 'I have no problem with negative feedback,' he told Anderson, in response to the latter's question. 'There have been hundreds of negative articles, and yet I've only spoken out a few times. I don't have a problem with critical reviews, I have a problem with false reviews.'"
astroengine writes "Decades of searching and a 7.5 billion Euro particle accelerator later, why is everyone so down on one of the biggest discoveries of the century? Well, as the evidence strengthens for a bona fide signal of a 'Standard Model' Higgs boson with a mass of 125 GeV, many scientists are disappointed that the discovery of an 'ordinary' — or 'vanilla' according to Caltech cosmologist Sean Carroll — Higgs removes any doubt for more exotic physics beyond the Standard Model. It's a strange juxtaposition; a profound discovery that's also an anticlimax. But to confirm the identity of the Higgs candidate, LHC physicists still need to measure the particle's spin. 'Until we can confidently tie down the particle's spin,' said CERN Research Director Sergio Bertolucci at this week's Rencontres de Moriond conference in Italy, 'the particle will remain Higgs-like. Only when we know that is has spin-zero will we be able to call it a Higgs.'"
gentryx writes "Newly found evidence supports earlier claims that Gustave Whitehead (a German immigrant, born Gustav Weißkopf, with Whitehead being the literal translation of Weißkopf) performed the first powered, controlled, heavier-than-air flight as early as 1901-08-14 — more than two years before the Wrights took off. A reconstructed image shows him mid-flight. A detailed analysis of said photo can be found here. Apparently the results are convincing enough that even Jane's chimes in. His plane is also better looking than the Wright Flyer I." (And when it comes to displacing the Wright brothers, don't forget Alberto Santos Dumont.)
Hugh Pickens writes writes "Discover Magazine reports that Hugo Chavez will apparently get an embalming job designed to keep him looking alive for decades similar to that of Russia's Vladimir Lenin, whose body still lies in a mausoleum in Moscow's Red Square, nearly 90 years after his death. So how do you preserve a human body for decades without it turning into a pile of melted tissue? First, get to work quickly. Upon death, the human body starts decomposing immediately. The way to stop it is with formaldehyde, a preservative used for the past century, which inhibits the enzyme decomposition as well as killing bacteria. 'You pump the chemical in, and as the formaldehyde hits the cells of the body, it firms up the protein of the cell, or fixates it,' says Vernie Fountain, head of the Fountain National Academy of Professional Embalming Skills in Springfield, Mo. 'That's what makes them stiff.' With a body that will have to be on display for years, it's likely to require a top-shelf, super-strong solution. 'If I were doing Hugo Chavez, I would strengthen the solution and use more preservative product,' says Fountain. Next, get a good moisturizer. Formaldehyde preserves, but it also dries out the body. Vaseline or other moisturizers can preserve the look of skin, according to Melissa Johnson Williams, executive director of the American Society of Embalmers. Finally keep cool. Heat decomposes a body so for long term preservation, the body has to be kept at the temperature of a standard kitchen refrigerator, somewhere in the mid-40s. Lastly, if Venezuelans really want to keep Hugo Chavez around forever, like many other world figures, there's only one solution that works, according to Fountain. 'The best form of preservation is mummification.'"
sciencehabit writes "It's the sort of abstract puzzle that keeps a scientist awake at night: Can you predict how three objects will orbit each other in a repeating pattern? In the 300 years since this 'three-body problem' was first recognized, just three families of solutions have been found. Now, two physicists have discovered 13 new families. It's quite a feat in mathematical physics, and it could conceivably help astrophysicists understand new planetary systems." The paper is available at arxiv.
