call -151 writes "An editorial appearing in the ACM notices complains about the effects of the Elsevier boycott particularly with respect to academics refusing to do unpaid review for for-profit journals, particularly the extortionate Elsevier journals. Mathematician Tim Gowers's post gave energy to this about a year ago and recently he reflected on progress in several directions, including developing new arXIv overlay journals. Not disclosed in the ACM editorial is that the author serves on three Elsevier editorial boards; I take it that his complaining about the difficulty of finding referees is an indication that the boycott is having some good effect. Open access issues in academic publishing have been discussed on Slashdot before and it's a good sign that the broader issue has been getting good exposure, including a reasonable White House directive in response to a strong petition effort."
ananyo writes "The brains of two rats on different continents have been made to act in tandem. When the first, in Brazil, uses its whiskers to choose between two stimuli, an implant records its brain activity and signals to a similar device in the brain of a rat in the United States. The U.S. rat then usually makes the same choice on the same task. Miguel Nicolelis, a neuroscientist at Duke University in Durham, North Carolina, says that this system allows one rat to use the senses of another, incorporating information from its far-away partner into its own representation of the world. 'It's not telepathy. It's not the Borg,' he says. 'But we created a new central nervous system made of two brains.' Nicolelis says that the work, published today, is the first step towards constructing an organic computer that uses networks of linked animal brains to solve tasks. But other scientists who work on neural implants are skeptical."
Last Thursday, we discussed news that millionaire Dennis Tito was planning a private mission to Mars in 2018, but details were sparse. Now, reader RocketAcademy writes that Tito has provided more information about the tip, and that he intends the mission to be manned: "Dennis Tito, the first citizen space explorer to visit the International Space Station, has created the Inspiration Mars Foundation to raise funds for an even more dramatic mission: a human flyby of the planet Mars. Tito, a former JPL rocket scientist who later founded the investment firm Wilshire Associates, proposes to send two Americans — a man and a woman — on a 501-day roundtrip mission which would launch on January 5, 2018. Technical details of the mission can be found in a feasibility analysis (PDF), which Tito is scheduled to present at the IEEE Aerospace Conference in March. Former NASA flight surgeon Dr. Jonathon Clark, who is developing innovative ways of dealing with radiation exposure during the mission, called the flight 'an Apollo 8 moment for the next generation.'"
astroengine writes "Astronomers have directly measured the spin of a black hole for the first time by detecting the mind-bending relativistic effects that warp space-time at the very edge of its event horizon. By monitoring X-ray emissions from iron ions (iron atoms with some electrons missing) trapped in the black hole's accretion disk, the rapidly-rotating inner edge of the disk of hot material has provided direct information about how fast the black hole is spinning. Astronomers used NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) — that was launched into Earth orbit in June 2012 — and the European observatory XMM-Newton measured X-ray radiation as a tool to directly infer the spin of NGC 1365's black hole. 'What excites me is the fact that we are able to do this for the very massive black holes at the centers of galaxies but we can also make the same measurement for black holes in our galaxy ... black holes that resulted from the explosion of a star ... The fact we can extend this from billions of solar masses to 10 solar masses is pretty cool,' Fiona Harrison, professor of physics and astronomy at the California Institute of Technology, Pasadena, Calif., and principal investigator of the NuSTAR mission, told Discovery News."
Velcroman1 writes "Biochemical engineers can now download a piece of software and with a few simple clicks, assemble the DNA for new life forms through their laptops. 'With the proper computer tools, biologists can write their own genetic code — and then turn that code into life,' said biochemist Omri Amirav-Drory, who founded Genome Compiler Corp., the company that sells the software. He demonstrated at a coffee shop early one morning by manipulating a bacteria's genes on his laptop. The synthetic biology app is still in beta; on Jan. 15, the company added an undo feature and support for new DNA file formats. Building creatures is increasingly like word processing, it would seem. But such is the strange reality in the age of cheap genome sequencing, DNA synthesizing and 'bioinformatics.'"
astroengine writes "Helped by the extensive coverage of eyewitness cameras, CCTV footage and a fortuitous observation made by the Meteosat-9 weather satellite, Jorge Zuluaga and Ignacio Ferrin of the University of Antioquia in Medellin, Colombia, have been able to reconstruct the most likely orbit of the meteoroid that slammed into the atmosphere over the Russian Urals region on Feb. 15. What's more, they know what type of space rock it was — the Chelyabinsk-bound meteoroid originated from an Apollo-class asteroid (PDF). Apollo asteroids are well-known near-Earth asteroids that cross the orbit of Earth. Around 5,200 Apollo asteroids are currently known, the largest being 1866 Sisyphus — a 10 kilometer-wide monster that was discovered in 1972."
New submitter jollyrgr3 writes "If William Shatner gets his wish, one of Pluto's two new moons will be named Vulcan. The two small moons were discovered recently, and the SETI Institute launched an online poll to let people choose names. Captain Kirk himself suggested the names Vulcan and Romulus. Vulcan was accepted as a candidate, and Shatner exhorted his Twitter followers to vote. Vulcan ended up winning by a landslide, taking 174,000 of the 450,000 total responses. The next highest was Cerberus at just shy of 100,000. The names still have to be approved by the International Astronomical Union, as they have the final say. Leonard Nimoy approves."
AstroPhilosopher writes "In a move not far removed from the model T-101, U.S. researchers have succeeded in re-animating a dead sparrow. Duke scientists were studying male behavior aggression among sparrows. They cleverly decided to insert miniaturized robotics into an empty sparrow carcass and operate it like a puppet (abstract). It worked; they noticed wing movements were a primary sign of aggression. Fortunately the living won out this time. The experiment stopped after the real sparrows tore off the robosparrow's head. But there's always a newer model on the assembly-line. Good luck sparrows." Bad Horse has not yet made a decision on the researchers' application.
Hugh Pickens writes "UPI reports that for the first time in the history of Nobel Prize, one of the Nobel Prize medals, along with the diploma presented by the Nobel committee, is on auction — with an opening bid of $250,000. Awarded to Francis Crick, who along with James Watson and Maurice Wilkins won the Nobel Prize for medicine in 1962 'for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material,' the medal will be auctioned off in New York City, by Heritage Auctions. The medal has been kept in a safe deposit box in California since Crick's widow passed away in 2007 and a portion of the proceeds will go to the Francis Crick Institute of disease research scheduled to open in London in 2015. '"By auctioning his Nobel it will finally be made available for public display and be well looked after. Our hope is that, by having it available for display, it can be an inspiration to the next generation of scientists," says Crick's granddaughter, Kindra Crick. "My granddad was honored to have received the Nobel Prize, but he was not the type to display his awards; his office walls contained a large chalkboard, artwork and a portrait of Charles Darwin."'"
Billy the Mountain writes "A small UK company is bringing new technology online that could reduce the prices of tantalum and titanium ten-fold. According to this piece in The Economist: A tantalising prospect, the key is a technique similar to smelting aluminum with a new twist: The metallic oxides are not melted as with aluminum but blended in powder form with a molten salt that serves as a medium and electrolyte. This technology is known as the FFC Cambridge Process. Other metals include Neodymium, Tungsten, and Vanadium."
carmendrahl writes "Photos used to be second-class citizens in the art world, not considered as prestigious as paintings or sculpture. But that changed in the 1990s. As daguerrotypes and the like started selling for millions of dollars, fakes also slipped in. Unfortunately, the art world didn't have good ways of authenticating originals. Cultural heritage researchers had to play catch-up, and quickly. Two fraud cases, one involving avant garde photographer Man Ray, turned photo conservation from a niche field into a mature science."
astroengine writes "According to preliminary orbital prediction models, comet C/2013 A1 will buzz Mars on Oct. 19, 2014. C/2013 A1 was discovered by ace comet-hunter Robert McNaught at the Siding Spring Observatory in New South Wales, Australia, on Jan. 3. When the discovery was made, astronomers at the Catalina Sky Survey in Arizona looked back over their observations to find "prerecovery" images of the comet dating back to Dec. 8, 2012. These observations placed the orbital trajectory of comet C/2013 A1 through Mars orbit on Oct. 19, 2014. Due to uncertainties in the observations — the comet has only been observed for 74 days (so far), so it's difficult for astronomers to forecast the comet's precise location in 20 months time — comet C/2013 A1 may fly past at a very safe distance of 0.008 AU (650,000 miles). But to the other extreme, its orbital pass could put Mars directly in its path."
Lasrick writes "This is just fascinating: Joe Henrich and his colleagues are shaking the foundations of psychology and economics, and explain why social science studies of Westerners — and Americans in particular — don't really tell us about the human condition: 'Given the data, they concluded that social scientists could not possibly have picked a worse population from which to draw broad generalizations. Researchers had been doing the equivalent of studying penguins while believing that they were learning insights applicable to all birds.'"
An anonymous reader writes "A small U.S. university has come up with a novel solution to reduce the possibility of using a dead person's hand to get past a fingerprint scanner through the use of hemoglobin detection. The device quickly checks the fingerprint and hemoglobin 'non-intrusively' to verify the identity and whether the individual is alive. This field of research is called Biocryptology and seeks to ensure that biometric security devices can't be easily bypassed."
ananyo writes "The drowned remnants of an ancient micro-continent may lie scattered beneath the waters between Madagascar and India, a new study suggests. Evidence for the long-lost land comes from Mauritius, a volcanic island about 900 kilometers east of Madagascar (abstract) The oldest volcanic rocks on the island date to about 8.9 million years ago. Yet grain-by-grain analyses of beach sand collected at two sites on the Mauritian coast revealed around 20 zircons — tiny crystals of zirconium silicate that are exceedingly resistant to erosion or chemical change — that were far older. One of these zircons was at least 1.97 billion years old. The researchers that made the discovery think that geologically recent volcanic eruptions brought shards of the buried continent to the Earth's surface, where the zircons eroded from their parent rocks to pepper the island's sands. Analyses of Earth's gravitational field reveal several broad areas where sea-floor crust at the bottom of the Indian ocean is much thicker than normal — at least 25 to 30 kilometers thick, rather than the normal 5 to 10 kilometers. Those crustal anomalies may be the remains of a landmass that researchers have now dubbed Mauritia, which they suggest split from Madagascar when tectonic rifting and sea-floor spreading sent the Indian subcontinent surging northeast millions of years ago."
