Precise W Boson Mass Measurement Helps Lead the Way To the Higgs Boson 82

Posted by Soulskill from the over-the-river-and-through-the-woods dept.
New submitter SchrodingerZ writes "'The world's most precise measurement of the mass of the W Boson, one of nature's elementary particles, has been achieved by scientists from the CDF and DZero collaborations at the Department of Energy's Fermi National Accelerator Laboratory.' This new number (80387 +- 17 MeV/c^2) puts more constraint on the mass of the theorized Higgs Boson, which is theorized to give mass to all other things, supporting the standard model. 'Scientists employ two techniques to find the hiding place of the Higgs particle: the direct production of Higgs particles and precision measurements of other particles and forces that could be influenced by the existence of a Higgs particle.'"

Growth of Pseudoscience Harming Australian Universities 566

Posted by Soulskill from the my-horoscope-said-the-same-thing dept.
wired_parrot writes "The international credibility of Australia's universities is being undermined by the increase in the 'pseudoscientific' health courses they offer, two academics write in a recent article decrying that a third of Australian universities now offer courses in such subjects as homeopathy and traditional Chinese medicine, which undermines science-based medicine. 'As the number of alternative practitioners graduating from tertiary education institutions increases, further health-care resources are wasted, while the potential for harm increases.'"

Free Program Predicts How Troublesome a Genetic Mutation Is 34

Posted by samzenpus from the giant-misprinted-book-that's-hidden-inside-you dept.
smoothjazz writes "Researchers describe a new, freely available Web-based program called Spliceman for predicting whether genetic mutations are likely to disrupt the splicing of messenger RNA, potentially leading to disease. From the article: 'Spliceman makes its predictions about mutations by calculating that distance. It has successfully predicted the known effect of many mutations. The software has genomic information about 11 species: humans, chimpanzees, rhesus monkeys, mice, rats, dogs, cats, chickens, guinea pigs, frogs, and zebra fish.'"

New Interface Could Wire Prosthetics Directly Into Amputees' Nervous Systems 160

Posted by samzenpus from the we-can-make-him-better dept.
cylonlover writes "Scientists at Sandia National Laboratories have announced a breakthrough in prosthetics that may one day allow artificial limbs to be controlled by their wearers as naturally as organic ones, as well as providing sensations of touch and feeling. The scientists have developed a new interface consisting of a porous, flexible, conductive, biocompatible material through which nerve fibers can grow and act as a sort of junction through which nerve impulses can pass to the prosthesis and data from the prosthesis back to the nerve. If this new interface is successful, it has the potential to one day allow nerves to be connected directly to artificial limbs."

Scientists Say People Aren't Smart Enough For Democracy To Flourish 1276

Posted by samzenpus from the you-voted-for-who? dept.
cold fjord writes "The inability of the incompetent to recognize their own limitations is a story that has been covered before on Slashdot. But, what happens when you apply that finding to politics? From the article: 'The democratic process relies on the assumption that citizens can recognize the best political candidate, or best policy idea. But a growing body of research has revealed an unfortunate aspect of the human psyche that would seem to disprove this notion, and imply instead that democratic elections produce mediocre leadership and policies. The research shows that incompetent people are inherently unable to judge the competence of other people, or the quality of those people's ideas. If people lack expertise on tax reform, it is very difficult for them to identify the candidates who are actual experts. They simply lack the mental tools needed to make meaningful judgments...democracies rarely or never elect the best leaders. Their advantage over dictatorships or other forms of government is merely that they "effectively prevent lower-than-average candidates from becoming leaders."'"

Asteroid Will Make Close Pass To Earth 119

Posted by samzenpus from the skin-of-your-teeth dept.
The Bad Astronomer writes "News is starting to spread about a small 45-meter-wide asteroid called 2012 DA14 that will make a close pass to Earth on February 15, 2013. However, some of these articles are claiming it has 'a good chance' of impacting the Earth. This is simply incorrect; the odds of an impact next year are essentially zero. Farther in the future the odds are unclear; another near pass may occur in 2020, but right now the uncertainties in the asteroid's orbit are too large to know much about that. More observations of DA14 are being made, and we should have better information about future encounters soon."

Museum of Engineered Organisms Opens In Pittsburgh 54

Posted by samzenpus from the it's-alive-alive dept.
qeorqe writes "The Center for PostNatural History is a museum and research library about organisms that have been created either by genetic engineering or selective breeding. Included in the collection are Sea Monkeys and GloFish. From the article: 'One of the cool things about natural history museums is that they show you how nature has changed over time, adapting to volatile conditions and extreme challenges. And nothing is more volatile, extreme, or challenging than the human race, so it makes sense that there would be a museum to chronicle just how much we’ve messed with plants, animals, the climate, and in general the world around us. The Center for PostNatural History, opening this week in Pittsburgh, is that museum.'"

Math Textbooks a Textbook Example of Bad Textbooks 446

Posted by samzenpus from the bottom-of-the-barrel dept.
theodp writes "Over at Salon, Annie Keeghan does an Upton Sinclair number on the math textbook industry. In recent years, Keeghan explains, math has become the subject du jour due to government initiatives and efforts to raise the rankings of lagging U.S. students. But with state and local budgets constrained, math textbook publishers competing for fewer available dollars are rushing their products to market before their competitors, resulting in product that in many instances is inherently, tragically flawed. Keeghan writes: 'There may be a reason you can't figure out some of those math problems in your son or daughter's math text and it might have nothing at all to do with you. That math homework you're trying to help your child muddle through might include problems with no possible solution. It could be that key information or steps are missing, that the problem involves a concept your child hasn't yet been introduced to, or that the math problem is structurally unsound for a host of other reasons.' The comments on Keeghan's article are also an eye-opener — here's a sample: 'Sales and marketing budgets are astronomical because the expenses pay off more than investments in product. Sadly, most teachers are not curriculum experts and are swayed by the surface pitches. Teachers make the decisions, but are not the users (students) nor are they spending their own money. As a result, products that make their lives easier and that come with free meals and gifts are the most successful.' So, can open source or competitions build better math textbooks?"

Mysterious Dark Matter Blob Confounds Experts 151

Posted by Soulskill from the dark-matter-needs-vacations-too dept.
mayberry42 writes "Astronomers using the Hubble Space Telescope are mystified by a merging galaxy cluster known as Abell 520 in which concentrations of visible matter and dark matter have apparently come unglued. A report on the Hubble observations, published in the Astrophysical Journal, raises more questions than answers about a cosmic pile-up that's occurring 2.4 billion light-years away. 'According to our current theory,' says Arif Babul, the study team's senior theorist, 'galaxies and dark matter are expected to stay together, even through a collision. But that's not what's happening in Abell 520. Here, the dark matter appears to have pooled to form the dark core, but most of the associated galaxies seem to have moved on.'"

Chrome Users Are Best With Numbers, IE Users Worst 203

Posted by Soulskill from the reopening-a-can-of-worms dept.
New submitter dr_blurb writes "After reading about last year's hoax report 'Intelligence Quotient (IQ) and Browser Usage' I realized I was in fact already running a real live experiment measuring number skills: a site were you can solve Calcudoku number puzzles. I analyzed two years' worth of data, consisting of over 1 million solved puzzles. This included puzzles solved 'against the clock,' of three different sizes. For each size, Chrome users were the fastest solvers, Firefox users came second, and IE users were the slowest. The number of abandoned puzzles (started but never finished) was also significantly higher for IE users. Analysis shows that the differences are statistically significant: in other words, they did not happen by chance. I put up more details and some graphs, and also wrote a paper about it (PDF)."

Could Curiosity Rover Moonlight As Part of a Sample Return Mission? 65

Posted by timothy from the be-grateful-for-infinite-resources dept.
pigrabbitbear writes "After recent budget cuts to NASA's Mars program, the agency's dream of a sample return mission within the next decade is dead in the water. But the $2.5 billion rover Curiosity is on its way to the red planet right now, and speculation is popping up online that it could fairly easily be retrofitted with the hardware needed to collect and store samples. Theoretically NASA would just need one more mission to collect and return those samples, turning Curiosity into the first phase of the sample return dream."

Oxygen Found Around Saturn's Moon Dione 58

Posted by Soulskill from the don't-plan-vacation-just-yet dept.
New submitter S810 writes "According to an article in Discovery News, oxygen was found by the Cassini spacecraft around Dione, one of Saturn's large moons. 'It is thought the oxygen is being produced via interactions between Saturn's powerful radiation belts and Dione's water ice. The radiation breaks the water molecules down, liberating oxygen into the moon's exosphere.' Hopefully this will open the door for more funding of research int the moons of Saturn and Jupiter."

Is Poor Numeracy Ruining Lives? 489

Posted by Soulskill from the mainly-restaurant-servers-lives dept.
Hugh Pickens writes "The BBC reports on how millions of people struggle to understand a payslip or a train timetable, or pay a household bill. Government figures show that almost half the working population of England have only primary school math skills, and research suggests that weak math skills are linked with an array of poor life outcomes such as prison, unemployment, exclusion from school, poverty and long-term illness. 'We are paying for this in our science, technology and engineering industries but also in people's own ability to earn funds and manage their lives,' says Chris Humphries. He is the chairman of National Numeracy, an organization seeking to emulate the success of the National Literacy Trust, which has helped improve reading and writing standards since it was set up nearly 20 years ago. The Department for Education wants the vast majority of young people to study math up to 18 within a decade to meet the growing demand for employees with high level and intermediate math skills. 'It is simply inexcusable for anyone to say "I can't do maths,"' adds Humphries. "

Warp Drives May Come With a Killer Downside 458

Posted by Soulskill from the or-a-killer-upside-if-you're-a-klingon dept.
An anonymous reader writes "Alcubierre warp-drives (theoretically) allow rocket ships to travel faster than the speed of light, while staying within the rules of Einstein's general theory of relativity. New research (PDF) has shown that as such warp-drives zip through the universe, they gather up particles and radiation, releasing them in a burst as the warp-drive slows down. This is bad news for family and friends waiting for the ship to arrive, as this intense burst will fry them."

Science and Engineering Workforce Has Stalled In the US 433

Posted by Soulskill from the reality-tv-workforce-booming dept.
dcblogs writes "The science and engineering workforce in the U.S. has flatlined, according to the Population Reference Bureau. As a percentage of the total labor force, S&E workers accounted for 4.9% of the workforce in 2010, a slight decline from the three previous years when these workers accounted for 5% of the workforce. That percentage has been essentially flat for the past decade. In 2000, it stood at 5.3%. The reasons for this trend aren't clear, but one factor may be retirements. S&E workers who are 55 and older accounted for 13% of this workforce in 2005; they accounted for 18% in 2010. 'This might imply that there aren't enough young people entering the S&E labor force,' said one research analyst."

One In Eight Chance of a Financially Catastrophic Solar Storm By 2020 337

Posted by Soulskill from the movie-rights-already-sold-to-syfy dept.
An anonymous reader writes "A privately employed solar scientist named Pete Riley estimates there's a 12 percent chance of a massive solar storm comparable to the Carrington Event in 1859 which resulted in breathtaking aurorae across the United States and other temperate regions of the globe. The electromagnetic surge from the 1859 event caused failures of telegraph systems across Europe and North America. A similar storm today could knock out power grids, GPS and communication satellites, data centers, transportation systems, and building and plumbing infrastructures and wreak $1 trillion or more of economic damage in the first year alone, according to a 2008 report from the National Academy of Sciences."

'Twisted' Waves Could Boost Capacity of Wireless Spectrum 147

Posted by Soulskill from the make-them-squirm dept.
New submitter Ogi_UnixNut writes "In Venice, Italy, physicists have shown that it is possible to use two beams of incoherent radio waves, transmitted on the same frequency but encoded in two different orbital angular momentum states, to simultaneously transmit two independent radio channels. In principle this allows the implementation of an infinite number of channels in a given, fixed bandwidth, even without using polarization, multiport or dense coding techniques. It's potentially a boon for congested spectrum problems, although at the moment I suspect it would only work for directional links."

Well, not according to researchers at Finland's Tampere University of Technology. They've developed a product known as RegJoint, which is reportedly the world's first biodegradable joint implant. Unlike permanent implants, it allows the patient's bone ends to remain intact, and it creates a new joint out of their own tissue."

coondoggie writes "The commercialization of all manner of space technologies has always been a forte of NASA, but the space agency faces a number of economic and internal challenges if that success is to continue. A report by released this week (PDF) by NASA Inspector General Paul Martin that assesses NASA's technology commercialization efforts is highly critical of the space agency's ability to identify and get important technologies out of the lab and out the door to commercial applications."
