An anonymous reader writes "A huge, lingering ridge of high pressure over the eastern half of the United States brought summer-like temperatures to North America in March 2012. The warm weather shattered records across the central and eastern United States and much of Canada. From the article: 'Records are not only being broken across the country, they're being broken in unusual ways. Chicago, for example, saw temperatures above 26.6Celsius (80Fahrenheit) every day between March 14-18, breaking records on all five days. For context, the National Weather Service noted that Chicago typically averages only one day in the eighties each in April. And only once in 140 years of weather observations has April produced as many 80Fahrenheit days as this March.'"

Hugh Pickens writes "Christopher Shea writes in the WSJ that physicists studying Google's massive collection of scanned books claim to have identified universal laws governing the birth, life course and death of words, marking an advance in a new field dubbed 'Culturomics': the application of data-crunching to subjects typically considered part of the humanities. Published in Science, their paper gives the best-yet estimate of the true number of words in English — a million, far more than any dictionary has recorded (the 2002 Webster's Third New International Dictionary has 348,000), with more than half of the language considered 'dark matter' that has evaded standard dictionaries (PDF). The paper tracked word usage through time (each year, for instance, 1% of the world's English-speaking population switches from 'sneaked' to 'snuck') and found that English continues to grow at a rate of 8,500 new words a year. However the growth rate is slowing, partly because the language is already so rich, the 'marginal utility' of new words is declining. Another discovery is that the death rates for words is rising, largely as a matter of homogenization as regional words disappear and spell-checking programs and vigilant copy editors choke off the chaotic variety of words much more quickly, in effect speeding up the natural selection of words. The authors also identified a universal 'tipping point' in the life cycle of new words: Roughly 30 to 50 years after their birth, words either enter the long-term lexicon or tumble off a cliff into disuse and go '23 skidoo' as children either accept or reject their parents' coinages."

MrSeb writes "In a world where warfare is fast becoming fielded by remote controlled and autonomous robots, innovation is the key to victory. The most technologically advanced superpower can see more, plan better, and attack from further away than its inferior adversaries. What better way to revolutionize the drone and robotics industry than use the brilliant minds of our children? That's what DARPA and the Defense Department's research and development arm thinks, anyway. The Manufacturing Experimentation and Outreach Initiative, part of the Adaptive Vehicle Make project, is slated to reach a thousand schools in and out of the country, roping in the brightest minds to develop robotics and advance technology in new and interesting ways. Funded by the Department of Defense, the program comes with a steep cost: The DoD wants unlimited rights to everything the students build. It sounds almost like something Orson Scott Card would dream up."

ananyo writes "The origin of multicellular life, one of the most important developments in Earth's history, could have occurred with surprising speed, U.S. researchers have shown. In the lab, a single-celled yeast (Saccharomyces cerevisiae) took less than 60 days to evolve into many-celled clusters that behaved as individuals. The clusters even developed a primitive division of labor, with some cells dying so that others could grow and reproduce. Multicellular life has evolved independently at least 25 times, but these transitions are so ancient that they have been hard to study. The researchers wanted to see if they could evolve multicellularity in a single-celled organism, using gravity as the selective pressure. In a tube of liquid, clusters of yeast cells settle at the bottom more quickly than single cells. By culturing only the cells that sank, they selected for those that stick together. After many rounds of selection over 60 days, the yeast had evolved into 'snowflakes' comprising dozens of cells."

sciencehabit writes "Is climate change education the new evolution, threatened in U.S. school districts and state education standards by well-organized interest groups? A growing number of education advocates believe so, and yesterday, the National Center for Science Education in Oakland, California, which fights the teaching of creationism, announced that it's going to take on climate change denial as well."

An anonymous reader writes "The Texas Board of Education has unanimously come down on the side of evolution. In an 8-0 vote, the board today approved scientifically accurate high school biology textbook supplements from established mainstream publishers — and did not approve the creationist-backed supplements from International Databases, LLC."

"Some voters in Las Vegas have noticed that Democrat Harry Reid's name is checked by default on their electronic voting machines. By way of explanation, the Clark County Registrar says that when voters choose English instead of Spanish, Reid's Republican opponent, Sharron Angle, has her name checked by default."

sciencehabit writes "Responding to a court order issued a week ago, the National Institutes of Health (NIH) on Friday ordered intramural researchers studying human embryonic stem cells (hESCs) to shut down their experiments. NIH's action — probably unprecedented in its history — is a response to a preliminary injunction on 23 August from US District Judge Royce Lamberth. The judge ruled that the Obama policy allowing NIH funding to be used to study hESC lines violates a law prohibiting the use of federal funds to destroy embryos."

An anonymous reader writes with this interesting bit of speculation: "NASA can put humanoids on the Moon in just 1000 days. They would be controlled by scientists on Earth using motion capture suits, giving them the feeling of being on the lunar surface. If they can achieve this for real, the results for science research of our satellite could be amazing."

theodp writes "After the morning commute from his Las Vegas apartment, Air Force captain Sam Nelson sits in a padded chair inside a low, tan building in Nevada, controlling a heavily armed drone aircraft soaring over Afghanistan, prepared to kill another human being 7,500 miles away if necessary. Welcome to the surreal world of drone pilots, who have a front-row seat on war from half a world away. 'On the drive out here, you get yourself ready to enter the compartment of your life that is flying combat,' explained retired Col. Chris Chambliss. 'And on the drive home, you get ready for that part of your life that's going to be the soccer game.' No wonder why the Air Force is interested in the Xbox LIVE crowd and the Army's opened a new arcade recruitment center!"

geegel writes "Space is a hostile environment for living things, but small organisms on the Expose-E experiment unit outside Europe's Columbus ISS laboratory module have resisted the solar UV radiation, cosmic rays, vacuum and varying temperatures for 18 months. A certain lichen seems to be particularly happy in open space."

anzha writes "Do you remember being a kid and told we'd never know what colors the dinosaurs were? For at least some, that's no longer true. Scientists working in the UK and China have closely examined the fossils of multiple theropods and actually found the colors and patterns that were present in the fossilized proto-feathers. So far, the answer is orange, black and white in banded and other patterns. The work also thoroughly thrashes the idea that fossils might not be feathers, but collagen fibers instead. If this holds up, Birds Are Dinosaurs. Period. And colorful!"
