cylonlover writes "Robot hedgehogs on the moons of Mars may sound like the title of a B-grade sci-fi movie, but that is what Stanford University is working on. Marco Pavone, an assistant professor in the Department of Aeronautics and Astronautics, and his team are developing spherical robots called 'hedgehogs' that are about half a meter (1.6 ft) wide and covered in spikes to better cope with rolling and hopping across the surface of the Martian moon Phobos with its very low gravity."

Dexter Herbivore sends this quote from the Washington Post: "Scientists analyzing Australian rocks have discovered traces of bacteria that lived a record-breaking 3.49 billion years ago, a mere billion years after Earth formed. If the find withstands the scrutiny that inevitably faces claims of fossils this old, it could move scientists one step closer to understanding the first chapters of life on Earth. The discovery could also spur the search for ancient life on other planets. These traces of bacteria 'are the oldest fossils ever described. Those are our oldest ancestors,' said Nora Noffke, a biogeochemist at Old Dominion University in Norfolk who was part of the group that made the find and presented it last month at a meeting of the Geological Society of America."

An article at Space.com forecasts an important year for private space companies in 2013. SpaceX is working on a new version of its Dragon capsule that is quite different from the current model. SpaceX CEO Elon Musk said that the first iteration looked similar to other space capsules because the SpaceX team was learning as they went. Now, they're drawing on the expertise they've gained to tailor the new capsule to their needs. "Musk described Dragon version 2 as having 'legs that pop out' and added that it uses parachutes and its eight SuperDraco thrusters for a 'propulsive landing.'" The capsule will hold up to seven people, and they hope to win a crew transportation contract for getting NASA astronauts up to the ISS. The bidding for that contract starts in the second half of 2013. Commercial space planes are also set to reach new heights in 2013. XCOR Aerospace will be building its Lynx I rocket plane, and a spokesman said, "we’ll be doing test fights throughout the year from early 2013 and then go into commercial flights." Virgin Galactic's SpaceShipTwo will also undergo its first rocket-powered flight this year.

An anonymous reader sends word that the Russian Space industry will be getting a big boost over the next eight years. Prime Minister Medvedev has approved $68.71 billion in space-related funding from 2013 to 2020. That's a huge increase from the $3.3 billion spent annually in 2010 and 2011. The increased funding is one of several efforts to restoring Russia's slowly fading spaceflight capabilities. "The failure of a workhorse Proton rocket after launch in August caused the multimillion-dollar loss of an Indonesian and a Russian satellite. A similar problem caused the loss of a $265 million communications satellite last year. Medvedev criticized the state of the industry in August, saying problems were costing Russia prestige and money." Medvedev said, "The program will enable our country to effectively participate in forward-looking projects, such as the International Space Station, the study of the Moon, Mars and other celestial bodies in the solar system."

EagleHasLanded writes "The U.S. Metric Association has been advocating for metrication since 1916 – without much success. In the mid-1970s, the U.S. government passed the Metric Conversion Act, but now it seems the time for complete conversion has come and gone. Or could U.S. educators and health & safety advocates put this issue back on Congress' radar screen?"

MarkWhittington writes "With the National Research Council report that concluded that President Obama's plan for a mission to an asteroid has no support, either inside NASA or anywhere else, the space agency faces a decision point in 2013. The NRC suggested that the administration, Congress, NASA, and other stakeholders in space exploration come to a consensus behind a new goal. But the space agency's problems run deep, caused by a lack of direction, a lack of leadership, and a lack of funding."

An anonymous reader writes "Pandas have long been the face of conservation efforts by environmental activists, but a recent finding may boost even further the need for pandas to evade extinction. Researchers have discovered a powerful antibody in panda blood that could serve as the next frontier in the fight against increasingly prevalent superbugs. The compound is called cathelicin-AM. Discovered when researchers analyzed the creatures' DNA, it has been found to kill fungus and bacteria. It is believed that the antibiotic is released to protect the animal from infections in the wild and, in studies, it has been found to kill both standard and drug-resistant strains of microbes and fungi. The compound also worked extremely quickly, killing off strains of bacteria in just an hour, while conventional antibiotics needed six."

A reader writes "Nobel winner Dr. Rita Levi-Montalcini, who discovered chemical tools that the body uses to direct cell growth and build nerves, has died. She was 103. From the article: 'Dr. Rita Levi-Montalcini, a Nobel Prize-winning neurologist who discovered critical chemical tools that the body uses to direct cell growth and build nerve networks, opening the way for the study of how those processes can go wrong in diseases like dementia and cancer, died on Sunday at her home in Rome. She was 103. Her death was announced by Mayor Gianni Alemanno of Rome. "I don't use these words easily, but her work revolutionized the study of neural development, from how we think about it to how we intervene," said Dr. Gerald D. Fishbach, a neuroscientist and professor emeritus at Columbia. Scientists had virtually no idea how embryo cells built a latticework of intricate connections to other cells when Dr. Levi-Montalcini began studying chicken embryos in the bedroom of her house in Turin, Italy, during World War II. After years of obsessive study, much of it at Washington University in St. Louis with Dr. Viktor Hamburger, she found a protein that, when released by cells, attracted nerve growth from nearby developing cells.'"

SchrodingerZ writes "In an upcoming BBC Documentary, Dean Armstrong, the brother of astronaut Neil Armstrong, reveals when the world famous 'one small step for man, one giant leap for mankind' line originated. For years, people have argued over when Armstrong came up with the line, whether it was on the spot or planned years ahead. Also debated is whether Armstrong meant to include 'a' before man, making the indefinite article 'man,' which alludes to mankind, into a singular, 'a man,' himself. According to Dean Armstrong, the quote was shared to him over a board game, months before the mission began. He says, 'We started playing Risk and then he [Neil] slipped me a piece of paper and said "read that." I did. On that piece of paper there was "That's one small step for man, one giant leap for mankind." He says "what do you think about that?" I said "fabulous." He said "I thought you might like that, but I wanted you to read it." He then added: "It was 'that is one small step for A man.'"' Armstrong had always insisted that he had said 'a,' that it was lost in communication static. This new story however conflicts with what Neil told James Hansen for his biography, stating he came up with the quote on the lunar surface. More on the historic moon landing and the life of Neil Armstrong in the new documentary Neil Armstrong- First Man on the Moon, on BBC."

kkleiner writes "A small handful of doctors in China are using a highly controversial procedure to rid people of drug addiction by destroying a part of patients' brains. The procedure involves drilling small holes into the skulls of patients and inserting long electrodes that destroy a part of the brain called the nucleus accumbens. This area, often referred to as the "pleasure center" of the brain, is the major nucleus of the brain's reward circuit. Is it worth being cured of addiction if, losing the addiction, we also lose part of who we are?" The practice has been officially banned, but apparently continues nonetheless.

Earth-like exoplanets have gotten a lot of attention in the last few years; it's exciting to think that there's life — or even just life-sustaining conditions — on planets other than Earth, whether near by (on Mars) or much farther away (orbiting Vega). Projects like NASA's Kepler, and the ground-based HARPS, attempt to spot planets outside our solar system of all kinds. These exoplanet discoveries have been ramping up lately, and so has sorting of the discovered planets by size and other characteristics; the odds are looking good, say astronomers quoted by Space.com, that an Earth-like planet will be found this year. Abel Mendez runs the Planetary Habitability Laboratory at the University of Puerto Rico at Arecibo, and UC Berkeley astromer Geoff Marcy looks for planets as part of the Kepler team; they explain in the article why they think 2013 is an auspicious one for planet hunters.

Hugh Pickens writes "Adam Nagourney reports that after a yearlong investigation a team of climate scientists announced that it is throwing out a reading of 136.4 degrees claimed by the city of Al Aziziyah, Libya on Sept. 13, 1922 making the 134-degree reading registered on July 10, 1913, at Greenland Ranch in Death Valley the official world record as the hottest place on earth. 'It's about time for science, but I think we all knew it was coming,' says Randy Banis. 'You don't underestimate Death Valley. Most of us enthusiasts are proud that the extremes that we have known about at Death Valley are indeed the most harsh on earth.' The final report by 13 climatologists appointed by the World Meteorological Organization, the climate agency of the United Nations, found five reasons to disqualify the Libya claim, including questionable instruments, an inexperienced observer who made the reading, and the fact that the reading was anomalous for that region and in the context of other temperatures reported in Libya that day. 'The more we looked at it, the more obvious it appeared to be an error,' says Christopher C. Burt, a meteorologist with Weather Underground who started the debate in a blog post in 2010."

cylonlover writes "NASA's Evolutionary Xenon Thruster (NEXT) ion engine has set a new world record by clocking 43,000 hours of continuous operation at NASA's Glenn Research Center's Electric Propulsion Laboratory. The seven-kilowatt thruster is intended to propel future NASA deep space probes on missions where chemical rockets aren't a practical option. The NEXT is one of NASA's latest generation of engines. With a power output of seven kilowatts, it's over twice as powerful as the ones used aboard the unmanned Dawn space probe, yet it is simpler in design, lighter and more efficient, and is also designed for very high endurance. Its current record of 43,000 hours is the equivalent of nearly five years of continuous operation while consuming only 770 kg (1697.5 lbs) of xenon propellant. The NEXT engine (PDF) would provide 30 million newton-seconds of total impulse to a spacecraft. What this means in simple terms is that the NEXT engine can make a spacecraft go (eventually) very far and very fast."

The next generation of Russian spacecraft will be ready for test flights by 2017, according to Energia President Vitaly Lopota. 'We have completed the technical design project taking into account the fact that the new spaceship is to fly to the Moon, among other places,' he said. Federal Space Agency Roscosmos head Vladimir Popovkin says the new ship would be built by 2018 and would be able to conduct missions to the International Space Station and the Moon.

A British plan to blast a path through more than two miles of ice to reach an Antarctic lake has been suspended because of technical problems. From the article: "In a move that clears the way for U.S. and Russian teams to take the lead, Professor Martin Siegert said technical problems and a lack of fuel had forced the closure on Christmas Day of the 7-million-pound ($11 million) project, which was looking for life forms and climate change clues in the lake-bed sediment. 'This is of course, hugely frustrating for us, but we have learned a lot this year,' said Siegert of the University of Bristol, principal investigator for the mission, which was headed by the British Antarctic Survey (BAS). 'By the end, the equipment was working well, and much of it has now been fully field-tested,' he said on the BAS website."

jomama717 writes "Another chapter in the fascinating life of Srinivasa Ramanujan appears to be complete: 'While on his death bed, the brilliant Indian mathematician Srinivasa Ramanujan cryptically wrote down functions he said came to him in dreams, with a hunch about how they behaved. Now 100 years later, researchers say they've proved he was right. "We've solved the problems from his last mysterious letters. For people who work in this area of math, the problem has been open for 90 years," Emory University mathematician Ken Ono said. Ramanujan, a self-taught mathematician born in a rural village in South India, spent so much time thinking about math that he flunked out of college in India twice, Ono said.'"

cylonlover writes "The SpaceX Grasshopper vertical takeoff vertical landing (VTVL) testbed has successfully flown to a height of 40 meters (131 ft), hovered for a bit and subsequently landed in a picture perfect test on December 17, 2012. The Grasshopper had previously taken two hops to less than 6 m (20 ft) in height, but the latest test was the first that saw it reach an altitude taller than the rocket itself, which is a modified Falcon 9 orbital launch vehicle. The flight lasted 29 seconds from launch to landing, and carried a 1.8 m (6 ft) cowboy dummy to give an indication of scale."
