Great White Shark RFID/Satellite Tracking Shows Long Journeys, Many Beach Visits 86

Lucas123 writes "Marine biologists from OCEARCH, a non-profit shark research project, have been tagging scores of great whites and other shark species with an array of wireless technologies, gathering granular data on the sharks over the past year or more. For example, Mary Lee, a great white shark that's the same weight and nearly the same length as a Buick, was tagged off of Cape Cod and has made beach visits up and down the U.S. East Coast and Bermuda. She came so close to beaches that the research team alerted local authorities. The team attaches an array of acoustic and satellite tags as well as accelerometers to the sharks, which collect more than 100 data points every second — 8.5 million data points per day. The data has provided a detailed, three-dimensional view of the shark's behavior, which the team has been sharing in real time on its website. OCEARCH plans to expand that data sharing over the next few weeks to social networks and classrooms."

Un-Un-Pentium On Your Periodic Table of the Elements? 172

PolygamousRanchKid writes, quoting Forbes "Researchers at Sweden's Lund University have announced that they've been able to confirm the existence of element 115 on the periodic table. This research team isn't the first to create element 115, which is currently known as ununpentium. The first claim that ununpentium had been synthesized in a lab was by a joint group of Russian and American researchers, who believed that they created it in their lab in 2004."

Brazilian Journals' Self-Citation Cartel Smashed 68

ananyo writes "Thomson Reuters has uncovered a Brazilian self-citation cartel in which editors of journals cited each other to boost their impact factors. The cartel grew out of frustration with the system for evaluating graduate programs, which places too much emphasis on publishing in 'top tier' journals, one of the editors claims. As emerging Brazilian journals are in the lowest ranks, few graduates want to publish in them. This vicious cycle, in his view, prevents local journals improving. Both the Brazilian education ministry and Thomson Reuters have censured the journals. The ministry says articles from the journals published in 2012-12 will not count in any future assessment, and Thomson Reuters has suspended their impact factors."

US Electrical Grid On the Edge of Failure 293

ananyo writes "Facebook can lose a few users and remain a perfectly stable network, but where the national grid is concerned, simple geography dictates that it is always just a few transmission lines from collapse, according to a mathematical study of spatial networks. The upshot of the study is that spatial networks are necessarily dependent on any number of critical nodes whose failure can lead to abrupt — and unpredictable — collapse. The warning comes ten years after a blackout that crippled parts of the midwest and northeastern United States and parts of Canada. In that case, a series of errors resulted in the loss of three transmission lines in Ohio over the course of about an hour. Once the third line went down, the outage cascaded towards the coast, cutting power to some 50 million people. The authors say that this outage is an example of the inherent instability the study describes. But others question whether the team's conclusions can really be extrapolated to the real world. 'The problem is that this doesn't reflect the physics of how the power grid operates,' says Jeff Dagle, an electrical engineer at the Pacific Northwest National Laboratory in Richland, Washington, who served on the government task force that investigated the 2003 outage."

XPrize Pulls Plug On $10 Million Genomics Competition 36

sciencehabit writes "The XPrize Foundation has scrapped its high-profile $10 million genomics challenge set for next month after attracting only two competitors to the sequencing contest. The Archon Genomics XPRIZE began with much fanfare 7 years ago with the aim of boosting medical genomics by offering a $10 million award to the first team to sequence 100 human genomes in 10 days for no more than $10,000 each. After complaints about the tight deadline and unclear judging criteria, the foundation revised the rules in October 2011: The objective was to sequence the genomes of 100 centenarians with high accuracy and 98% completeness within 30 days for $1000 or less. Interest was tepid, however, and only two of the eight contenders in the original contest registered by the 31 May deadline — the company Ion Torrent, and George Church's lab at Harvard University."

Measles Outbreak Tied To Texas Megachurch 622

New submitter the eric conspiracy sends this quote from NBC: "An outbreak of measles tied to a Texas megachurch where ministers have questioned vaccination has sickened at least 21 people, including a 4-month-old infant — and it's expected to spread further, state and federal health officials said. 'There's likely a lot more susceptible people,' said Dr. Jane Seward, the deputy director for the viral diseases division at the Centers for Disease Control and Prevention. ... All of the cases are linked to the Eagle Mountain International Church in Newark, Texas, where a visitor who'd traveled to Indonesia became infected with measles – and then returned to the U.S., spreading it to the largely unvaccinated church community, said Russell Jones, the Texas state epidemiologist. ... Terri Pearsons, a senior pastor of Eagle Mountain International said she has had concerns about possible ties between early childhood vaccines and autism. In the wake of the measles outbreak, however, Pearsons has urged followers to get vaccinated and the church has held several vaccination clinics. ... 'In this community, these cases so far are all in people who refused vaccination for themselves and their children,' [Steward] added. The disease that once killed 500 people a year in the U.S. and hospitalized 48,000 had been considered virtually eradicated after a vaccine introduced in 1963. Cases now show up typically when an unvaccinated person contracts the disease abroad and spreads it upon return to the U.S."

The Game Made From NASA Satellite Data 32

An anonymous reader writes "Kickstarter's helped start all sorts of indie games, but few as unusual as Lacuna Passage, an adventure game set on Mars with a vast open world that's been painstakingly recreated from NASA satellite data. You're able to explore twenty five square miles of the Red Planet in all its barren glory as you attempt to solve the mystery of the first, vanished, manned mission to mars. A new piece today on the making of the game — which is being made by an elementary school teacher and a team of a dozen volunteers — looks at how it came about, and why their quest for authenticity led to even urine analysis being included in the gameplay."

Video Why We Need to Keep Our Night Skies Dark (Video) 130

Kelly Beatty has a unique perspective on the world of astronomy: Beatty's been on the staff of Sky & Telescope magazine for nearly 40 years as a writer and editor, including a stint heading "Night Sky" magazine. He's also written what's been called "the definitive guide for the armchair astronomer," and teaches astronomy to people of all ages. (He even has an asteroid named after him.) Besides being fascinated with the objects we can see in Earth's skies, Beatty takes the skies themselves seriously: his Twitter handle is NightSkyGuy for a reason. We talked a few weeks ago, in dark-skied rural Maine, about his involvement with the International Dark-Sky Association, and why you should care about ubiquitous light pollution, even if you don't have a deep interest in star-gazing. (And it's not just to be courteous to your neighbors.)

PTSD-Monitoring App Captured the Psychological Effects of the Boston Bombing 68

the_newsbeagle writes "This DARPA-funded smartphone app is designed to monitor veterans for signs of depression and PTSD. It screens for signals of psychological distress in a number of ways; for example, the app looks for signs of social isolation (reduced number of phone calls and texts), physical isolation (the phone isn't leaving the house), and sleep disruption (the phone is used in the middle of the night). Interestingly, the company that invented the app was testing it in Boston at the time of the Boston marathon bombing, and reports that the app picked up signals of distress in the days after the attack."

UW Researchers Demonstrate First Direct Communication Between Human Brains 154

An anonymous reader writes "Opening a fascinating set of ethical and legal issues, researchers at UW Seattle have demonstrated the first device to allow direct communication between two humans' brains. Effectively, they allowed a subject to play a video game with another subject's fingers. For now, the communication is uni-directional, though they intend to extend it to bi-directional. EEG sensors are attached to a subject's motor cortex to detect 'motor imagery' — imagined hand movement, in this case. That activity is translated and sent over a computer network where it triggers a Transcranial Magnetic Stimulator (TMS) located over Subject 2's motor cortex. Effectively, Subject 1 imagines moving their hand, and Subject 2's hand moved."

Just Thinking About Science Triggers Moral Behavior 347

ananyo writes "The association between science and morality is so ingrained that merely thinking about it can trigger more moral behavior, according to a study by researchers at the University of California Santa Barbara. The researchers hypothesized that there is a deep-seated perception of science as a moral pursuit — its emphasis on truth-seeking, impartiality and rationality privileges collective well-being above all else. The researchers conducted four separate studies to test this. In the first, participants read a vignette of a date-rape and were asked to rate the 'wrongness' of the offense before answering a questionnaire measuring their belief in science. Those reporting greater belief in science condemned the act more harshly. In the other three, participants primed with science-related words were more altruistic."

Bionic Skin: the Killer App For Flexible Electronics 46

the_newsbeagle writes "Most of the researchers who work on flexible electronics imagine putting their materials to use in flexible displays, like a rollable, foldable iPad that you could cram in your pocket. And I'm not saying that wouldn't be cool. But researcher Takao Someya of the University of Tokyo has a different idea: He wants his ultra-thin, ultra-flexible electronics to be used as bionic skin. Someya and other researchers have created circuits that stick to your skin, and that can stretch and bend as you move your body. These materials are still in the labs, but the scientists imagine many uses for them. For example, if a synthetic skin is studded with pressure and heat sensors, it could be used as a lifelike covering for prosthetic limbs. There are also potential biomedical applications: The e-skin could discreetly monitor an outpatient's vital signs, and send the data to a nearby computer. The article includes a short video showing Someya's material in action."

Galileo: Right On the Solar System, Wrong On Ice 206

carmendrahl writes "Famed astronomer Galileo Galilei is best known for taking on the Catholic Church by championing the idea that the Earth moves around the sun. But he also engaged in a debate with a philosopher about why ice floats on water. While his primary arguments were correct, he went too far, belittling legitimate, contradictory evidence given by his opponent, Ludovico delle Colombe. Galileo's erroneous arguments during the water debate are a useful reminder that the path to scientific enlightenment is not often direct and that even our intellectual heroes can sometimes be wrong."

Synchronized Virtual Reality Heartbeat Triggers Out-of-Body Experiences 183

Zothecula writes "New research demonstrates that triggering an out-of-body experience (OBE) could be as simple as getting a person to watch a video of themselves with their heartbeat projected onto it. According to the study, it's easy to trick the mind into thinking it belongs to an external body and manipulate a person's self-consciousness by externalizing the body's internal rhythms. The findings could lead to new treatments for people with perceptual disorders such as anorexia and could also help dieters too."

The Next US Moonshot Will Launch From Virginia 92

As reported by the Washington Post, a U.S. spacecraft headed for the moon (to circle it, though, not to land) is to be launched for the first time from the facility at Virginia's Wallops Island. If you'll be in the D.C. area on the night of September 6 and the weather cooperates enough for a launch, it should be worth staying up for. "The robotic mission is to collect detailed information about the moon's thin atmosphere. Sometimes thought to be nonexistent, the lunar atmosphere has been described as extremely tenuous and fragile, but present. According to the space agency, the launch will record many firsts. One will be the first launch beyond Earth orbit from the Virginia facility. It also will be the first flight for the Minotaur V rocket, NASA said. NASA said the five-stage Air Force rocket is an excess ballistic missile that was transformed into a space-launch vehicle. It will boost the space probe into position for it to reach lunar orbit." Though the satellite is NASA's, the launch will be controlled by Orbital Sciences.

Using Pulsars As GPS For Starships 103

cold fjord writes with an excerpt from Science Codex: "CSIRO scientists have written software that could guide spacecraft to Alpha Centauri ... Dr George Hobbs (CSIRO) and his colleagues study pulsars — small spinning stars that deliver regular 'blips' or 'pulses' of radio waves and, sometimes, X-rays. Usually the astronomers are interested in measuring, very precisely, when the pulsar pulses arrive in the solar system. Slight deviations from the expected arrival times can give clues about the behaviour of a pulsar itself ... 'But we can also work backwards,' said Dr Hobbs. 'We can use information from pulsars to very precisely determine the position of our telescopes.' 'If the telescopes were on board a spacecraft, then we could get the position of the spacecraft.' Observations of at least four pulsars, every seven days, would be required. ... A paper (paywalled) describing in detail how the system would work has been accepted for publication by the journal Advances in Space Research." (Here is a related story from the same source.)

International Effort Could Put First Canadian On the Moon 152

A long-term plan created by 14 cooperating space agencies around the world could mean that a Canadian astronaut may get to visit the moon sometime close to 2030. The International Space Exploration Coordination Group, of which Canada is a part, released last week an updated roadmap laying out intended projects, including a lunar visit. "[CSA space exploration director Jean-Claude Piedboeuf] suggested astronauts could again be moon-bound in about 15 years. It would be the first human visit to the shining orb since 1972, when NASA astronauts Eugene Cernan and Harrison Schmidt spent 75 hours there. This time, there could well be Canadian visitors. Their specialty: robotics. 'We're proposing a vision where Canada could have an astronaut, effectively a Canadian who will be in lunar space, either in orbit or on the moon and could operate a Canadian rover in the same way that Canadians operate a Canadarm on the space station,' Piedboeuf said."

This Satellite Could Be Beaming Solar Power Down From Space By 2025 245

Daniel_Stuckey writes "A NASA veteran, aerospace entrepreneur, and space-based solar power (SBSP) expert, [John] Mankins designed the world's first practical orbital solar plant. It's called the Solar Power Satellite via Arbitrarily Large PHased Array, or SPS-ALPHA for short. If all goes to plan, it could be launched as early as 2025, which is sooner than it sounds when it comes to space-based solar power timelines. Scientists have been aware of the edge the "space-down" approach holds over terrestrial panels for decades. An orbiting plant would be unaffected by weather, atmospheric filtering of light, and the sun's inconvenient habit of setting every evening. SBSP also has the potential to dramatically increase the availability of renewable energy."
