HungWeiLo writes "A California man who believes the literal interpretation of the Bible is real is offering $10,000 to anyone who can successfully debunk claims made in the book of Genesis in front of a judge. Joseph Mastropaolo, the man behind this challenge, is to put $10,000 of his own money into an escrow account. His debate opponent would be asked to do the same. They would then jointly agree on a judge based on a list of possible candidates. Mastropaolo said that any evidence presented in the trial must be 'scientific, objective, valid, reliable and calibrated.' For his part, Mastropaolo has a Ph.D. in kinesiology and writes for the Creation Hall of Fame website, which is helping to organize the minitrial. It's also not the first such trial he's tried to arrange. A previous effort, known as the 'Life Science Prize,' proposed a similar scenario. Mastropaolo includes a list of possible circuit court judges to oversee the trial and a list of those he challenged to take part on the evolutionary side of the debate."
sciencehabit writes "The electric fields that build up on honey bees as they fly, flutter their wings, or rub body parts together may allow the insects to talk to each other, a new study suggests. Tests show that the electric fields, which can be quite strong, deflect the bees' antennae, which, in turn, provide signals to the brain through specialized organs at their bases. Antenna deflections induced by an electrically charged honey bee wing are about 10 times the size of those that would be caused by airflow from the wing fluttering at the same distance—a sign that electrical fields could be an important signal."
coondoggie writes "How is spacecraft development — from the space parts supply chain to actual space operations — protected from those who would try to penetrate or disrupt the networks involved in that process? The U.S. Air Force Research Laboratory (AFRL) has put out a call for research to understand that security scenario. They say, 'we are much less concerned about information on the broader themes of cyber-security but rather those that pertain to the mission of the spacecraft, the spacecraft as a platform, the systems that constitute the spacecraft, the computers and their software, the busses and networks within, and the elements that interface to the spacecraft.'"
sciencehabit writes "Researchers who mapped methane concentrations on the streets of the nation's capital found natural gas leaks everywhere, at concentrations of up to 50 times the normal background levels. The leaking gas wastes resources, enhances ozone production, and exacerbates global warming—not to mention powering the city's infamous exploding manholes. Most of the natural gas we burn for heat and on stovetops in the United States is methane, a simple carbon atom surrounded by four hydrogens. Carbon dioxide gets more press, but methane is the more powerful agent of global warming, 21 times more effective than carbon dioxide at trapping heat in the atmosphere. And methane levels are rising fast. Methane levels in the atmosphere were just 650 parts per billion a century ago, versus 1800 ppb today."
ananyo writes "In a twist that evokes the dystopian science fiction of writer Philip K. Dick, neuroscientists have found a way to predict whether convicted felons are likely to commit crimes again from looking at their brain scans. Convicts showing low activity in a brain region associated with decision-making and action are more likely to be arrested again, and sooner. The researchers studied a group of 96 male prisoners just before their release. They used functional magnetic resonance imaging (fMRI) to scan the prisoners' brains during computer tasks in which subjects had to make quick decisions and inhibit impulsive reactions. The scans focused on activity in a section of the anterior cingulate cortex (ACC), a small region in the front of the brain involved in motor control and executive functioning. The researchers then followed the ex-convicts for four years to see how they fared. Among the subjects of the study, men who had lower ACC activity during the quick-decision tasks were more likely to be arrested again after getting out of prison, even after the researchers accounted for other risk factors such as age, drug and alcohol abuse and psychopathic traits."
We've mentioned over the last few years several times the funding problems that mean the U.S. government's weather satellite stable is thinner than we might prefer. A story at the Weather Underground outlines the plan of a company called PlanetIQ to fill the needs met with the current constellation of weather sats with private ones instead. From the article, describing testimony last week before the House Appropriations Subcommittee on Commerce: "PlanetIQ's solution includes launching a constellation of 12 small satellites in low-Earth orbit to collect weather data, which PlanetIQ says the federal government could access at less cost and risk than current government-funded efforts. ... [PlanetIQ Anne Hale] Miglarese added that within 28 to 34 months from the beginning of their manufacture, all 12 satellites could be in orbit. As for the cost, she says, "We estimate that for all U.S. civilian and defense needs globally for both terrestrial and space weather applications, the cost to government agencies in the U.S. will be less than $70 million per year. As the satellites collect data, PlanetIQ would sell the data to government weather services around the world as well as the U.S. Air Force. The most recently launched polar-orbiting satellite, sent into space by the U.S. in 2011, cost $1.5 billion."
A year ago James Cameron made history by traveling solo almost seven miles deep in an area of the Pacific Ocean known the Mariana Trench’s Challenger Deep. He made the trip in a submersible he helped design, the Deepsea Challenger submersible system and science platform. To celebrate the anniversary, Cameron is forming a partnership with Woods Hole Oceanographic Institution (WHOI), and donating the Deep Sea Challenger. From the press release: "Cameron will transfer the Deepsea Challenger to Woods Hole, where WHOI scientists and engineers will work with Cameron and his team to incorporate the sub’s numerous engineering advancements into future research platforms and deep-sea expeditions. This partnership harnesses the power of public and private investment in supporting deep-ocean science. “The seven years we spent designing and building the Deepsea Challenger were dedicated to expanding the options available to deep-ocean researchers. Our sub is a scientific proof-of-concept, and our partnership with the Woods Hole Oceanographic Institution is a way to provide the technology we developed to the oceanographic community,” says Cameron. James even sent us a few early drawings of the Deepsea Challenger that he made during a conversation with oceanographer Don Walsh in November 2003. The sketches are proof that many great ideas start out on napkins or lined paper.
Hugh Pickens writes writes "Richard Gray reports that scientists have found a way to help anyone plagued by those annoying tunes that lodge themselves inside our heads and repeat on an endless loop — when snippets of a catchy song inexplicably play like a broken record in your brain. The solution can be to solve some tricky anagrams to force the intrusive music out of your working memory allowing the music to be replaced with other more amenable thoughts. 'The key is to find something that will give the right level of challenge,' says Dr Ira Hyman, a music psychologist at Western Washington University who conducted the research. 'If you are cognitively engaged, it limits the ability of intrusive songs to enter your head.' Hyman says that the problem, called involuntary memory retrieval, is that something we can do automatically like driving or walking means you are not using all of your cognitive resource, so there is plenty of space left for that internal jukebox to start playing. Dr Vicky Williamson, a music psychologist at Goldsmiths, University of London, says that the most likely songs to get stuck are those that are easy to hum along to or sing and found that that Lady Gaga was the most common artist to get stuck in people's heads, with four of her catchy pop songs being the most likely to become earworms – Alejandro, Bad Romance, Just Dance and Paparazzi. Other surveys have reported Abba songs such as Waterloo, Changes by David Bowie or the Beatles' Hey Jude."
Zothecula writes "We haven't heard anything from NASA's Landsat Data Continuity Mission (LDCM) spacecraft since its launch in February, but the satellite is now ready to start sending its first images back home. The first batch of photos are part of a three-month testing period, and show the meeting of the Great Plains with the Front Ranges of the Rocky Mountains in Wyoming and Colorado. Viewed from space, it's already a pretty spectacular scene, but the images from the LDCM managed to enhance it even further."

Created by a research team from China's Zhejiang University in the Department of Polymer Science and Engineering lab headed by Professor Gao Chao, the ultra-light aerogel has a density of just 0.16 mg/cm3, which is lower than that of helium and just twice that of hydrogen."
cold fjord writes "It looks like deep sea exploration may pay off big time as Japanese scientists have located rich deposits of rare earth elements on the sea floor in Japanese Exclusive Economic Zone waters, following up on their find two years ago of huge deposits of rare earths in mid-Pacific waters. The cumulative effect of these finds could significantly weaken Chinese control of 90% of the world supply of rare earth metals, which the Chinese have been using to flex their muscles. The concentration of rare earth metals in the Japanese find is astonishing: up to 6,500 ppm, versus 500-1,000 ppm for Chinese mines. The newly identified deposits are just 2-4 meters below sea floor which could make for relatively easy mining compared to the 10+ meters they were expecting... if they can get there. The fact that the deposits are 5,700 meters deep means there is just one or two little problems to resolve : 'A seabed oil field has been developed overseas at a depth of 3,000 meters. . . But the development of seabed resources at depths of more than 5,000 meters has no precedent, either at home or abroad. There remains a mountain of technological challenges, including how to withstand water pressure and ocean currents and how to process the mining products in the ocean, sources said.'"

Linux runs everywhere at SpaceX, he said, on everything from desktops to spacecraft."
California doesn't get all the action; The Washington Post is one of many news outlets reporting that the east coast of North America got a good view of a meteor, with more than 300 sightings from Canada to Florida. Did you see it? If so, did you have your dashcam on? Update: 03/23 13:43 GMT by T : The meteor was captured at least by some security cameras, as reported by The Guardian.
coondoggie writes "Researchers at DARPA want to take the science of machine learning — teaching computers to automatically understand data, manage results and surmise insights — up a couple notches. Machine learning, DARPA says, is already at the heart of many cutting edge technologies today, like email spam filters, smartphone personal assistants and self-driving cars. 'Unfortunately, even as the demand for these capabilities is accelerating, every new application requires a Herculean effort. Even a team of specially-trained machine learning experts makes only painfully slow progress due to the lack of tools to build these systems,' DARPA says."
Techmeology writes "In a survey of UK GPs, 97% said they'd recommended placebo treatments to their patients, with some doctors telling patients that the treatment had helped others without telling them that it was a placebo. While some doctors admitted to using a sugar pill or saline injection, some of the placebos offered had side effects such as antibiotic treatments used as placebos for viral infections."
skade88 writes "Reuters is reporting that scientists now say the universe is 100 million years older than previously thought after they took a closer look at leftover radiation from the Big Bang. This puts the age of the Universe at 13.8 billion years. The new findings are the direct results from analyzing data provided by the European Space Agency's Planck spacecraft. The spacecraft is providing the most detailed look to date at the remnant microwave radiation that permeates the universe. 'It's as if we've gone from a standard television to a high-definition television. New and important details have become crystal clear,' Paul Hertz, NASA's director of astrophysics, told reporters on a conference call."
Trepidity writes "The extensive NASA Technical Report Archive was just taken offline, following pressure from members of U.S. Congress, worried that Chinese researchers could be reading the reports. U.S. Representative Frank Wolf (R-VA) demanded that 'NASA should immediately take down all publicly available technical data sources until all documents that have not been subjected to export control review have received such a review,' and NASA appears to have complied. Although all reports are in the public domain, there doesn't appear to be a third-party mirror available (some university libraries do have subsets on microfiche)."

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."

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.'"
