Getting Students To Think At Internet Scale
Hugh Pickens writes "The NY Times reports that researchers and workers in fields as diverse as biotechnology, astronomy, and computer science will soon find themselves overwhelmed with information — so the next generation of computer scientists will have to learn think in terms of Internet scale of petabytes of data. For the most part, university students have used rather modest computing systems to support their studies, but these machines fail to churn through enough data to really challenge and train young minds to ponder the mega-scale problems of tomorrow. 'If they imprint on these small systems, that becomes their frame of reference and what they're always thinking about,' said Jim Spohrer, a director at IBM's Almaden Research Center. This year, the National Science Foundation funded 14 universities that want to teach their students how to grapple with big data questions. Students are beginning to work with data sets like the Large Synoptic Survey Telescope, the largest public data set in the world. The telescope takes detailed images of large chunks of the sky and produces about 30 terabytes of data each night. 'Science these days has basically turned into a data-management problem,' says Jimmy Lin, an associate professor at the University of Maryland." -
EPA To Reuse Toxic Sites For Renewable Energy
Hugh Pickens writes:"The Daily Climate reports that President Obama and Congress are pushing to identify thousands of contaminated landfills and abandoned mines — 'brownfields' that could be repurposed to house wind farms, solar arrays, and geothermal power plants. Using already disturbed lands would help avoid conflicts between renewable energy developers and environmental groups concerned about impacts to wildlife habitat. 'In the next decade there's going to be a lot of renewable energy built, and all that has to go somewhere,' said Jessica Goad, an energy and climate change policy fellow for The Wilderness Society. 'We don't want to see these industrial facilities placed on land that's pristine. We love the idea of brownfields for renewable energy development because it relieves the (development) pressure on undisturbed places. The Environmental Protection Agency and the National Renewable Energy Laboratory have identified nearly 4,100 contaminated sites deemed economically suitable for wind and solar power development, as well as biomass. Included are 5 million acres suitable for photovoltaic or concentrated solar power development, and 500,000 acres for wind power. These sites, if fully developed, have the potential to produce 950,000 megawatts — more than the country's total power needs in 2007, according to EPA data." -
Gigantic Air Gun To Blast Cargo Into Orbit
Hugh Pickens writes: "The New Scientist reports that with a hat tip to Jules Verne's From the Earth to the Moon , physicist John Hunter has outlined the design of a gigantic gun that could slash the cost of putting cargo into orbit. At the Space Investment Summit in Boston last week, Hunter described the design for a 1.1-kilometer-long gun that he says could launch 450-kilogram payloads at 6 kilometers per second. A small rocket engine would then boost the projectile into low-Earth orbit. The gun would cost $500 million to build, says Hunter, but individual launch costs would be lower than current methods. 'We think it's at least a factor of 10 cheaper than anything else,' Hunter says. The gun is based on the SHARP (Super High Altitude Research Project) light gas gun Hunter helped to build in the 1990s while at the Lawrence Livermore National Laboratory (LLNL) in California. With a barrel 47 meters long, it used compressed hydrogen gas to fire projectiles weighing a few kilograms at speeds of up to 3 kilometers per second." -
Rupert Murdoch Says Google Is Stealing His Content
Hugh Pickens writes Weston Kosova writes in Newsweek that Rupert Murdoch gave an impassioned speech to media executives in Beijing decrying that search engines — in particular Google — are stealing from him, because Google links to his stories but doesn't pay News Corp. to do so. 'The aggregators and plagiarists will soon have to pay a price for the co-opting of our content,' Murdoch says. 'But if we do not take advantage of the current movement toward paid content, it will be the content creators — the people in this hall — who will pay the ultimate price and the content kleptomaniacs who triumph.' But if Murdoch really thinks Google is stealing from him, and if he really wants Google to stop driving all those readers to his Web sites at no charge, he can simply stop Google from linking to their news stories by going to his Web site's robot.txt file and adding 'Disallow.'" -
Why AT&T Should Dump the iPhone's Unlimited Data Plan
Pickens writes "Farhad Manjoo has a provocative story at Slate asserting that while the iPhone has prompted millions of people to join AT&T, it has also hurt the company's image because all of those customers use their phones too much, and AT&T's network is getting crushed by the demand. The typical smartphone customer consumes about 40 to 80 megabytes of wireless capacity a month, while the typical iPhone customer uses 400 MB a month. As more people sign up, local cell towers get more congested, and your own phone performs worse. He says the problem is that a customer who uses 1 MB a month pays the same amount as someone who uses 1,000 MB, and the solution is tiered pricing. 'Of course, users would cry bloody murder at first,' writes Manjoo. 'I'd call on AT&T to create automatic tiers — everyone would start out on the $10/100 MB plan each month, and your price would go up automatically as your usage passes each 100 MB tier.' He says the key to implementing the policy is transparency, and that the iPhone should have an indicator like the battery bar that changes color as you pass each monthly tier. 'Some iPhone fans will argue that metered pricing would kill the magic of Apple's phone — that sense of liberation one feels at being able to access the Internet from anywhere, at any time. The trouble is, for many of us, AT&T's overcrowded network has already killed that sense, and now our usual dealings with Apple's phone are tinged with annoyance.'" -
Penny-Sized Nuclear Batteries Developed
pickens writes "Nuclear batteries that produce energy from the decay of radioisotopes are an attractive proposition for many applications because the isotopes that power them can provide a useful amount of current for hundreds of years at power densities a million times as high as standard batteries. Nuclear batteries have been used for military and aerospace applications for years, their large size has limited their general usage. But now a research team at the University of Missouri has developed a nuclear battery the size of a penny that could be used to power micro- and nano-electromechanical systems. The researchers' innovation is not only in the battery's size, but also that the batteries use a liquid semiconductor rather than a solid semiconductor. 'The critical part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure of the solid semiconductor,' says Jae Wan Kwon. 'By using a liquid semiconductor, we believe we can minimize that problem.' The batteries are safe under normal operating conditions. 'People hear the word "nuclear" and think of something very dangerous,' says Kwon. 'However, nuclear power sources have already been safely powering a variety of devices, such as pacemakers, space satellites, and underwater systems.'" -
Photoshop Disaster Draws DMCA Notice For Boing Boing
Pickens writes: "Cory Doctorow writes that Ralph Lauren issued a DMCA takedown notice after Boing Boing republished the Photoshop disaster contained in a Ralph Lauren advertisement in which a model's proportions appear to have been altered to give her an impossibly skinny body with the model's head larger than her pelvis. Doctorow says that one of the things that makes their ISP Priority Colo so awesome is that they don't automatically act on DMCA takedowns and proceeded to dare Lauren to sue. 'This is classic fair use: a reproduction "for purposes such as criticism, comment, news reporting," etc,' writes Doctorow. 'Copyright law doesn't give you the right to threaten your critics for pointing out the problems with your offerings.' Doctorow adds that every time Lauren threatens to sue he will 'reproduce the original criticism, making damned sure that all our readers get a good, long look at it,' 'publish your spurious legal threat along with copious mockery,' and 'offer nourishing soup and sandwiches to your models.'" -
Captain Bligh's Logbooks To Yield Climate Bounty
Pickens writes "The BBC reports that researchers are digitizing the captains' logs from the voyages of Charles Darwin on HMS Beagle, Captain Cook from HMS Discovery, Captain Bligh from The Bounty, and 300 other 18th and 19th century ships' logbooks to provide historical climate records for modern-day climate researchers who will use the meteorological data to build up a picture of weather patterns in the world at the beginning of the industrial era. The researchers are cross-referencing the data with historical records for crop failures, droughts and storms and will compare it with data for the modern era in order to predict similar events in the future. 'The observations from the logbooks on wind force and weather are astonishingly good and often better than modern logbooks,' says Climatologist Dr. Dennis Wheeler from the University of Sunderland. 'Of course the sailors had to be conscientious. The thought that you could hit a reef was a great incentive to get your observations absolutely right!' The logbooks will be online next year at the UK's National Archives." -
50 Years of the Twilight Zone
pickens writes "Fifty years ago on October 2, American television viewers first heard the words: 'You're moving into a land of both shadow and substance, of things and ideas. You've just crossed over into... the Twilight Zone.' Like the time-space warps that anchored so many of the show's plots, Rod Serling's veiled commentary remains as soul-baring today as it did a half-century ago, and the show's popularity endures in multiple facets of American pop culture, appearing nearly uninterrupted through television, syndication and DVD releases and under license to air in 30 countries. 'The whole idea of "The Twilight Zone" jumped off the television screen and became a catchphrase, a buzzword for something much beyond the TV show itself,' says Robert Thompson, director of the Center for the Study of Popular Television at Syracuse University. 'When you say Twilight Zone, it's its own genre.' The original show ran just five seasons, 1959 to 1964, with 156 episodes filmed; Serling wrote 92 of them, and other contributors included Richard Matheson and Ray Bradbury. Anniversary observances were held at Ithaca College in New York, where Serling taught from 1967 until his death in 1975, and which keeps Serling's archives; and also at Antioch College in Ohio, where Serling was a student." -
Oracle Fined For Benchmark Claims
pickens writes "Information Week reports that the Transaction Processing Council, which sets benchmarks for measuring database performance, has fined Oracle $10,000 for Oracle's ads published August 27 and September 3 on the front page of the Wall Street Journal which violate the 'fair use' rules that govern TPC members by 'comparing an existing TPC result to something that does not exist.' The ads said to expect a product announcement on October 14 that would demonstrate that some sort of hybrid Oracle-Sun setup would offer two-digit performance on the TPC-C online transaction processing test compared to IBM's 6 million transaction per minute result on its Power 595 running AIX and DB2. The TPC Council serves as a neutral forum where benchmark results are aired and compared. 'At the time of publication, they didn't have anything' submitted to the council says Michael Majdalany, administrator of the council adding that that Oracle is free to use TPC numbers once it submits an audited result for the Sun-Oracle system. Fines by the TPC are infrequent, with the last action — a $5,000 fine — levied against Microsoft in 2005 for unsupported claims about SQL Server. 'It takes a fairly serious violation to warrant a member being fined,' says Majdalany." -
Massachusetts Police Can't Place GPS On Autos Without Warrant
pickens writes "The EFF reports that the Supreme Court of Massachusetts has held in Commonwealth v. Connolly that police may not place GPS tracking devices on cars without first getting a warrant, reasoning that the installation of the GPS device was a seizure of the suspect's vehicle. Search and seizure is a legal procedure used in many civil law and common law legal systems whereby police or other authorities and their agents, who suspect that a crime has been committed, do a search of a person's property and confiscate any relevant evidence to the crime. According to the decision, 'when an electronic surveillance device is installed in a motor vehicle, be it a beeper, radio transmitter, or GPS device, the government's control and use of the defendant's vehicle to track its movements interferes with the defendant's interest in the vehicle notwithstanding that he maintains possession of it.' Although the case only protects drivers in Massachusetts, another recent state court case, People v. Weaver in the State of New York, also held that because modern GPS devices are far more powerful than beepers, police must get a warrant to use the trackers, even on cars and people traveling the public roads." -
Professor Wins $240K In Fair Use Dispute
pickens writes "In a victory for Fair Use, Stanford Law School's Fair Use Project has announced that the estate of 20th century literary giant James Joyce, author of the landmark novel Ulysses, has agreed to pay $240,000 in attorneys' fees to Stanford University Consulting Professor Carol Shloss and her counsel in connection with Shloss's lawsuit to establish her right to use copyrighted material in her scholarship on the literary work of James Joyce. When Shloss used copyrighted materials in her biography of Joyce's daughter Lucia, titled Lucia Joyce: To Dance in the Wake, she had to excise a substantial amount of source material from the book in response to threats from the Joyce Estate. However following publication of the book, Shloss sued the Estate to establish her right to publish the excised material. The parties reached a settlement regarding the issue in 2007, permitting the publication of the copyrighted material in the US. Following the settlement, Shloss asked the Court to order the Estate to pay attorneys' fees of more than $400,000. She has now agreed to accept an immediate payment of $240,000 in return for the dismissal of the Estate's appeal. 'This case shows there are solutions to the problem Carol Shloss faced other than simple capitulation,' says Fair Use Project Executive Director Anthony Falzone, who led the litigation team." -
Universal "Death Stench" Repels Bugs of All Types
Hugh Pickens writes "Wired reports that scientists have discovered that insects from cockroaches to caterpillars all emit the same stinky blend of fatty acids when they die and that the death mix may represent a universal, ancient warning signal to avoid their dead or injured. 'Recognizing and avoiding the dead could reduce the chances of catching the disease,' says Biologist David Rollo of McMaster University 'or allow you to get away with just enough exposure to activate your immunity.' Researchers isolated unsaturated fatty acids containing oleic and linoleic acids from the corpses of dead cockroaches and found that their concoction repelled not just cockroaches, but ants and caterpillars. 'It was amazing to find that the cockroaches avoided places treated with these extracts like the plague,' says Rollo. Even crustaceans like woodlice and pillbugs, which diverged from insects 400 million years ago, were repelled leading scientists to think the death mix represents a universal warning signal. Scientists hope the right concoction of death smells might protect crops. Thankfully, human noses can't detect the fatty acid extracts. 'I've tried smelling papers treated with them and don't smell anything strong and certainly not repellent,' writes Rollo in an e-mail. 'Not like the rotting of corpses that occurs later and is detectable from great distances.'" -
Gravitational Currents Could Slash Fuel Needed For Space Flight
Hugh Pickens writes "BBC reports that scientists are mapping the gravitational corridors created from the complex interplay of attractive forces between planets and moons that can be used to cut the cost of journeys in space. 'Basically the idea is there are low energy pathways winding between planets and moons that would slash the amount of fuel needed to explore the solar system,' says Professor Shane Ross from Virginia Tech. 'These are free-fall pathways in space around and between gravitational bodies. Instead of falling down, like you do on Earth, you fall along these tubes.' The pathways connect Lagrange points where gravitational forces balance out. Depicted by computer graphics, the pathways look like strands of spaghetti that wrap around planetary bodies and snake between them. 'If you're in a parking orbit round the Earth, and one of them intersects your trajectory, you just need enough fuel to change your velocity and now you're on a new trajectory that is free,' says Ross. 'You could travel between the moons of Jupiter essentially for free. All you need is a little bit of fuel to do course corrections.' The Genesis spacecraft used gravitational pathways that allowed the amount of fuel carried by the probe to be cut 10-fold, but the trade off is time. While it would take a few months to get around the Jovian moon system using gravitational currents (PDF), attempting to get a free ride from Earth to Mars on the currents might take thousands of years." -
Mafia Sinks Ships Containing Toxic Waste
Hugh Pickens writes "For years there have been rumors that the mafia was sinking ships with nuclear and other waste on board as part of a money-making racket. Now, BBC reports on a sunken vessel that has been found 30km off the coast of Italy. Murky pictures taken by a robot camera show the vessel intact, and alongside it are a number of yellow barrels with labels indicating the contents are toxic. The ship's location was revealed by Francesco Fonti, an ex-member of Calabria's feared 'Ndrangheta crime group, who confessed to using explosives to sink this vessel and two others as part of an illegal operation to bypass rules on the disposal of toxic waste. Experts are now examining samples taken from the wreck, and an official says that if the samples prove to be radioactive then a search for up to 30 other sunken vessels believed scuttled by the mafia would begin immediately. 'The Mediterranean is 0.7 percent of the world's seas. If in this tiny portion there are more than 30 (toxic waste) shipwrecks, imagine what there could be elsewhere,' says Silvestro Greco, head of Calabria's environment agency." -
The Case For Mandatory Touch-Typing In High School
Hugh Pickens writes "With the perspective of forty-plus years since my graduation, I would say the single most useful course I took in high school was a business class in touch-typing that gave me a head start for writing and with computers that I have benefited from my entire life. So it was with particular interest that I read Gordon Rayner's essay in the Telegraph proposing that schools add a mandatory course in touch typing to the cornerstones of education: reading, writing and arithmetic. 'Regardless of the career a child takes up when they leave school, a high percentage of them will use a keyboard in their daily work, and all of them are likely to use a keyboard in their leisure time,' writes Rayner. 'Touch-typing would help every child throughout their lives — so why are our schools so blind to this?'" -
Password Hackers Do Big Business With Ex-Lovers
Hugh Pickens writes "The Washington Post reports that disgruntled lovers and spouses considering divorce are flocking to services like YourHackerz.com that boast they have little trouble hacking into Web-based e-mail systems like AOL, Yahoo, Gmail, Facebook and Hotmail. The services advertise openly, and there doesn't appear to be much anyone can do about it because while federal law prohibits hacking into e-mail, without further illegal activity, it's only a misdemeanor, says Orin Kerr, a law professor at George Washington University. 'The feds usually don't have the resources to investigate and prosecute misdemeanors,' says Kerr. 'And part of the reason is that normally it's hard to know when an account has been compromised, because e-mail snooping doesn't leave a trace.' It's not clear where YourHackerz.com is located, but experts suspect that most password hacking businesses are based overseas." -
Has Texting Replaced Talking For Teens?
Hugh Pickens writes "Sue Shellenbarger has an interesting essay in the WSJ where she talks about the 2,000 incoming text messages her son racks up every month — more than 60 two-way communications via text message every day — and her surprise that 2,000 monthly text messages is about average for today's teenagers. 'I have seen my son suffer no apparent ill effects (except a sore thumb now and then), and he reaps a big benefit, of easy, continuing contact with many friends,' writes Shellenbarger. 'Also, the time he spends texting replaces the hours teens used to spend on the phone; both my kids dislike talking on the phone, and say they really don't need to do so to stay in touch with friends and family.' But does texting make today's kids stupid, as Mark Bauerlein writes in his book ' The Dumbest Generation: How the Digital Age Stupefies Young Americans and Jeopardizes Our Future? 'I don't think so. It may make them annoying, when they try to text and talk to you at the same time,' writes Shellenbarger, adding, 'I have found him more engaged and easier to communicate with from afar, because he is constantly available via text message and responds with a faithfulness and speed that any mother would find reassuring.'" -
Symantec Wants To Use Victims To Hunt Computer Criminals
Hugh Pickens writes "Business Week reports that security experts plan to recruit victims and other computer users to help them go on the offensive and hunt down hackers. '"It's time to stop building burglar alarms to keep people out and go after the bad guys," says Rowan Trollope, senior vice-president for consumer products at Symantec, the largest maker of antivirus software. Symantec will ask customers to opt in to a program that will collect data about attempted computer intrusions and then forward the information to authorities. Symantec will also begin posting the FBI's top 10 hackers and their schemes on its Web site, where customers go for software updates and next year the company will begin offering cash bounties for information leading to an arrest. The strategy has its risks as hackers who find novices on their trail may trash their computers or steal their identities as punishment. Citizen hunters could also become cybervigilantes and harm bystanders as they pursue criminals but Symantec is betting customers won't mind being disrupted if they can help snare the bad guys. "I'm convinced we can clean up the Internet in 10 years if we can peel away the dirt and show people the threats they're facing," says Trollope.'" -
All Humans Are Mutants, Say Scientists
Hugh Pickens writes "In 1935, JBS Haldane, one of the founders of modern genetics, studied a group of men with the blood disease hemophilia and speculated that there would be about 150 new mutations in each human being. Now BBC reports that scientists have used next generation sequencing technology to produce a far more direct and reliable estimate of the number of mutations by looking at thousands of genes belonging to two Chinese men who are distantly related, having shared a common ancestor who was born in 1805. To establish the rate of mutation, the team examined an area of the Y chromosome which is unique because, apart from rare mutations, the Y chromosome is passed unchanged from father to son so mutations accumulate slowly over the generations. Despite many generations of separation, researchers found only 12 differences among all the DNA letters examined. The two Y chromosomes were still identical at 10,149,073 of the 10,149,085 letters examined." -
Making Babies In Space May Not Be Easy
Hugh Pickens writes "Studies of reproduction in space have previously been carried out with sea urchins, fish, amphibians and birds, but Brandon Keim writes in Wired that Japanese biologists have discovered that although mammalian fertilization may take place normally in space, as mouse embryos develop in microgravity their cells have trouble dividing and maturing. The researchers artificially fertilized mouse eggs with sperm that had been stored inside a three-dimensional clinostat, a machine that mimics weightlessness by rotating objects in such a way that the effects of gravity are spread in every direction. Some embryos were ultimately implanted in female mice and survived to a healthy birth, but at lower numbers than a regular-gravity control group. Part of the difference could be the result of performing tricky procedures on sensitive cells, but the researchers suspect they also reflect the effect of a low-gravity environment on cellular processes that evolved for Earth-specific physics. '"These results suggest for the first time that fertilization can occur normally under G environment in a mammal, but normal preimplantation embryo development might require 1G," concludes the report. "Sustaining life beyond Earth either on space stations or on other planets will require a clear understanding of how the space environment affects key phases of mammalian reproduction."'" -
Piranha Discovered In UK's Devon River
Hugh Pickens writes "With razor-sharp teeth piranha, native to the Amazon basin, the Orinoco and the rivers of the Guyanas, are generally considered to be the most ferocious freshwater fish in the world with a voracious appetite for meat, able to strip the flesh of large animals within minutes when traveling in a shoal. So when members of the British Environment Agency were conducting a sampling trip in the East Okement tributary of the River Torridge, they were amazed to see a large tail emerge from the undercut bank on the far side of the river. 'What we actually discovered was something we would not expect to find in our wildest dreams — we could hardly believe our eyes,' says Eddie Stevens. 'Our first thought was that a sea trout had become lodged in amongst the rocks and debris collected under the bank, but when it was removed from the river we were speechless to find it was a piranha.' Tests carried out on the dead piranha revealed it had been eating sweet corn, which proved it must have been kept as a pet. The Environment Agency said it believes the piranha was alive when it was put in the river, possibly because at 35 cm it had become too big for its tank. 'Whilst piranhas can't survive the colder climates of the UK, this latest find highlights a real issue — that releasing unwanted exotic pets or plants into rivers can have serious consequences for native wildlife,' says spokesman Paul Gainey. 'Rather than dumping things in the wild, we would urge people to seek advice about what to do with exotic species.'" -
Dad Builds 700 Pound Cannon for Son's Birthday
Hugh Pickens writes "The Charleston Daily Mail reports that machinist Mike Daugherty built his son a working cannon for his birthday — not a model — a real working cannon. 'It looks like something right out of the battle at Gettysburg,' says Daugherty. The 700 pound cast iron and steel howitzer, designed to use comparatively small explosive charges to propel projectiles at relatively high trajectories with a steep angle of descent, has a 4-inch gun barrel that is 36 inches long mounted on a wooden gun carriage with two 36- inch diameter wheels and took Daugherty about two weeks to build at a cost of about $6,000. 'I've always been interested in the Civil War and cannons, so I thought it would be a good gift,' says Daugherty's 11-year old son Logan. Daugherty said he is not worried about the federal government coming to get his son's cannon because he spoke to the federal Bureau of Alcohol, Tobacco, Firearms and Explosives and found it is legal to own such a cannon because it does not use a firing pin and is muzzle loaded so the government does not consider the weapon a threat. Two days after the family celebrated Logan's 11th birthday, father and son offered a field demonstration of the new cannon on top of a grassy hill overlooking Fairmont, West Virginia and on the third try, the blank inside the barrel went boom and a cannon was born. For a followup they popped a golf ball into the gun barrel, lit the fuse, and watched the golf ball split the sky and land about 600 yards away. 'Any rebels charging up this hill would be in trouble with a cannon like this at the top,' Logan says." -
Laughing Gas Is Major Threat To Ozone Layer
Hugh Pickens writes "The Christian Science Monitor reports that according to new research, nitrous oxide, the colorless, sweet-smelling gas with a long history as a medical and dental anesthetic is the next big threat to Earth's protective ozone layer. Its role in destroying ozone has long been recognized, as well as its role as a heat-trapping greenhouse gas but the new study puts nitrous oxide's ability to deplete ozone into numbers comparable to those used for other ozone-depleting gases covered by the 1987 Montreal Protocol. The researchers note that the health of the ozone layer has been improving since the adoption of the protocol and that nitrous oxide looms large today as an artificial destroyer of the ozone layer, in part because the emissions of other harmful chemicals have been so sharply reduced." (Continues.) "Globally, Earth's ozone layer has thinned by 5 to 6 percent since 1980, before CFCs and their ilk came into wide use, according to Akkihebbal Ravishankara, who led the study. He and his colleagues note that 6 percent may appear to be a small number, but it still can lead to significant effects on organisms at Earth's surface. The researchers did not make any policy recommendations in light of their finding. 'It is not for us to gauge how much risk there is,' says Ravishankara. In any event, Ravishankara says, at the moment researchers could not say with confidence 'how much nitrous oxide comes from where.'" -
James Murdoch Criticizes BBC For Providing "Free News"
Hugh Pickens writes "News Corporation's James Murdoch says that a 'dominant' BBC threatens independent journalism in the UK and that free news on the web provided by the BBC made it 'incredibly difficult' for private news organizations to ask people to pay for their news. 'It is essential for the future of independent digital journalism that a fair price can be charged for news to people who value it,' says Murdoch. 'The expansion of state-sponsored journalism is a threat to the plurality and independence of news provision.' In common with the public broadcasting organizations of many other European countries, the BBC is funded by a television license fee charged to all households owning a television capable of receiving broadcasts. Murdoch's News Corporation, one of the world's largest media conglomerates, owns the Times, the Sunday Times and Sun newspapers and pay TV provider BSkyB in the UK and the New York Post, Wall Street Journal, and Fox News TV in the US." Note that James Murdoch is the son of Rupert Murdoch. -
Treasured "Moon Rock" Is Petrified Wood
Hugh Pickens writes "BBC reports that a treasured piece at the Dutch national museum — a supposed moon rock from the first manned lunar landing given to former Prime Minister Willem Drees during a goodwill tour by the three Apollo-11 astronauts shortly after their moon mission in 1969 — has been revealed as nothing more than petrified wood, curators say. A jagged fist-size stone with reddish tints, it was mounted and placed above a plaque that said, 'With the compliments of the Ambassador of the United States of America... to commemorate the visit to The Netherlands of the Apollo-11 astronauts.' The plaque does not specify that the rock came from the moon's surface. Researchers from Amsterdam's Free University said they could see at a glance the rock was probably not from the moon. They followed the initial appraisal up with extensive testing. 'It's a nondescript, pretty-much-worthless stone,' wrote Geologist Frank Beunk in an article published by the museum. Beunk says the rock, which the museum at one point insured for more than half a million dollars, was worth no more than $70. The 'rock' had originally been been vetted through a phone call to NASA. As the US Embassy in the Hague said it was investigating the matter, the Rijksmuseum says it will keep the piece as a curiosity." -
Bug Means High School Students' Schedule Errors May Last Days
Hugh Pickens writes "The Washington Post reports that thousands of high school students in Prince George's County missed a third day of classes Wednesday, and school officials said it could take more than a week to sort out the chaos caused by a computerized class-scheduling system as students were placed in gyms, auditoriums, cafeterias, libraries and classes they didn't want or need at high schools across the county and their parents' fury over the logistical nightmare rose. 'The school year comes up the same time every year,' said Carolyn Oliver, the mother of a 16-year-old senior who spent Wednesday in the senior lounge at Bowie High School. 'When I heard they didn't have schedules, I was like, "What have they been doing all summer?"' When school opened Monday, about 8,000 high school students had no class schedules and were sent to wait in holding spaces while administrators tried to sort things out." (More below.) -
Depression May Provide Cognitive Advantages
Hugh Pickens writes "Paul W. Andrews and J. Anderson Thomson, Jr. argue in Scientific American that although depression is considered a mental disorder, depression may in fact be a mental adaptation which provides real benefits. This is not to say that depression is not a problem. Depressed people often have trouble performing everyday activities, they can't concentrate on their work, they tend to socially isolate themselves, they are lethargic, and they often lose the ability to take pleasure from such activities such as eating and sex. So what could be so useful about depression? 'Depressed people often think intensely about their problems,' write the authors. 'These thoughts are called ruminations; they are persistent and depressed people have difficulty thinking about anything else. Numerous studies have also shown that this thinking style is often highly analytical. They dwell on a complex problem, breaking it down into smaller components, which are considered one at a time.' Various studies have found that people in depressed mood states are better at solving social dilemmas and there is evidence that people who get more depressed while they are working on complex problems in an intelligence test tend to score higher on the test (PDF). 'When one considers all the evidence, depression seems less like a disorder where the brain is operating in a haphazard way, or malfunctioning. Instead, depression seems more like the vertebrate eye — an intricate, highly organized piece of machinery that performs a specific function.'" -
Bioreactors Engineer Tissue To Mend Heart Damage
Hugh Pickens writes "Heart attacks usually cause irreversible damage to heart muscle and, because cells lost from the heart do not grow back naturally, leave the organ in a weakened and vulnerable state that may cause another serious condition — called heart failure — if the victim survives. Now a team of scientists led by Tal Dvir from Ben-Gurion University of the Negev in Beer-Sheva has developed a tissue-engineering technique, using the body as a 'bioreactor,' to create a 'patch' made from heart muscle that can be used to fix scarring left over from a heart attack. First, a biodegradable 'scaffold' is seeded with immature cells taken from the hearts of newborn rats. For 48 hours, the scaffold is exposed to a cocktail of growth-promoting chemicals in the laboratory and is then transplanted into a rat's abdomen where it develops a network of blood vessels and muscle fibers. After seven days the patch is removed and grafted onto the animal's heart. A month later the patch has completely integrated itself into the heart, synchronizing its 'beat' with that of the surrounding tissue. 'Using the body as a bioreactor to engineer cardiac tissue with stable and functional blood vessel networks represents a significant improvement in cardiac patch performance over ex vivo (outside the body) methods currently used for patch production,' write the authors. The technique is also being developed for livers and bladders." -
Offshore Drilling Rigs Vulnerable To Hackers
Hugh Pickens writes "Foreign Policy magazine reports that a research team from the SINTEF Group, an independent Norwegian think tank, has warned oil companies worldwide that offshore oil rigs are highly vulnerable to hacking as they shift to unmanned robot platforms where vital operations — everything from data transmission to drilling to sophisticated navigation systems that maintain the platform's position over the wellhead — are controlled via wireless links to onshore facilities. 'The worst-case scenario, of course, is that a hacker will break in and take over control of the whole platform,' says Martin Gilje Jaatun, adding that it hasn't happened yet, but computer viruses have caused personnel injuries and production losses on North Sea platforms. The list of potential cyberattackers includes ecowarriors aiming to jack up an oil firms' production costs, extortionists drawn to oil firms' deep pockets, and foreign governments engaging in a strategic contest for ever-more-scarce global oil reserves, says Jeff Vail, a former counterterrorism and intelligence analyst with the US Interior Department. 'It's underappreciated how vulnerable some of these systems are,' says Vail. 'It is possible, if you really understood them, to cause catastrophic damage by causing safety systems to fail.'" -
Why the Google Android Phone Isn't Taking Off
Hugh Pickens writes "Farhad Manjoo writes in Slate that while the iPhone commands nearly 14 percent of smartphone sales and BlackBerry about 21 percent, Android has only 3 percent. And even though Android is far friendlier to developers, it has failed to attract anywhere near the number of apps now clogging the iPhone. Manjoo writes that Google went wrong by giving handset manufacturers and carriers too much control over the design and marketing of Android phones so there is no idealized 'Google phone' — instead, Android devices get names like the T-Mobile G1 or the myTouch 3G, and each is marketed separately and comes with its own distinct capabilities and shortcomings. 'Outside handset manufacturers lack ambition — -none of them even seems to be trying to match the capabilities of the iPhone, let alone to knock us down with features that far surpass those of Apple's device,' writes Manjoo. 'A smart handset manufacturer could build a top-of-the-line Android device that outshines Apple's phone in at least a few areas — better battery life, a much better Web browser, a brighter or bigger screen, faster or more functional controls... something that might help Android inspire gadget lust. But so far, that's not happening.' John Gruber echoes this advice and adds this advice to Android manufacturers: 'If Apple is BMW, you can be Porsche.'" -
BrainPort Lets the Blind "See" With Their Tongues
Hugh Pickens writes "Scientific American reports that a new device called 'BrainPort' aims to restore the experience of vision for the blind and visually impaired by relying on the nerves on the tongue's surface to send light signals to the brain. BrainPort collects visual data through a small digital video camera and converts the signal into electrical pulses sent to the tongue via a 'lollipop' that sits directly on the tongue, where densely packed nerves receive the incoming electrical signals. White pixels yield a strong electrical pulse and the electrodes spatially correlate with the pixels, so that if the camera detects light fixtures in the middle of a dark hallway, electrical stimulations will occur along the center of the tongue. Within 15 minutes of using the device, blind people can begin interpreting spatial information. 'At first, I was amazed at what the device could do,' says research director William Seiple. 'One guy started to cry when he saw his first letter.'" There is some indication that the signals from the tongue are processed by the visual cortex. The company developing the BrainPort will submit it to the FDA for approval later this month, and it could be on sale (for around $10,000) by the end of the year. -
US Life Expectancy May Have Peaked
Hugh Pickens writes "Live Science reports that although life expectancy in the United States has risen to an all-time high of 77.9 years in 2007 up from 77.7 in 2006, gains in life expectancy may be pretty much over, as some groups — particularly people in rural locations are already stagnating or slipping in contrast to all other industrialized nations. Hardest hit are regions in the Deep South, along the Mississippi River, in Appalachia and also the southern part of the Midwest reaching into Texas. The culprits — largely preventable with better diet and access to medical services — are diabetes, cancers and heart disease caused by smoking, high blood pressure and obesity. What the new analysis reveals is the reality of two Americas, one on par with most of Europe and parts of Asia, and another no different than a third-world nation with the United States placing 41st on the 2008 CIA World Factbook list, behind Bosnia but still edging out Albania. 'Beginning in the early 1980s and continuing through 1999 those who were already disadvantaged did not benefit from the gains in life expectancy experienced by the advantaged, and some became even worse off,' says a report published in PLoS Medicine by a team led by Harvard's Majid Ezzati, adding that 'study results are troubling because an oft-stated aim of the US health system is the improvement of the health of "all people, and especially those at greater risk of health disparities.'" -
US Navy Tries To Turn Seawater Into Jet Fuel
Hugh Pickens writes "New Scientist reports that, faced with global warming and potential oil shortages, the US Navy is experimenting with making jet fuel from seawater by processing seawater into unsaturated short-chain hydrocarbons that with further refining could be made into kerosene-based jet fuel. The process involves extracting carbon dioxide dissolved in the water and combining it with hydrogen — obtained by splitting water molecules using electricity — to make a hydrocarbon fuel, a variant of a chemical reaction called the Fischer-Tropsch process, which is used commercially to produce a gasoline-like hydrocarbon fuel from syngas, a mixture of carbon monoxide and hydrogen often derived from coal. The Navy team have been experimenting to find out how to steer the CO2-producing process away from producing unwanted methane by finding a different catalyst than the usual one based on cobalt. 'The idea of using CO2 as a carbon source is appealing,' says Philip Jessop, a chemist at Queen's University adding that to make a jet fuel that is properly 'green,' the energy-intensive electrolysis that produces the hydrogen will need to use a carbon-neutral energy source; and the complex multi-step process will always consume significantly more energy than the fuel it produces could yield. 'It's a lot more complicated than it at first looks.'" -
Why the BSA Is Less Reviled Than the RIAA
Hugh Pickens writes "The Business Software Alliance (BSA) is a trade group established in 1988 representing a number of the world's largest software makers whose principal activity is trying to stop copyright infringement of software produced by its members, performing roughly the same function for the software industry that the RIAA performs for the music industry. Yet, as Bill Patry, author of a 7-volume treatise on US copyright law and currently Senior Copyright Counsel at Google, notes on his blog the BSA is a 'far less unpopular organization' than the RIAA because there are three key differences between the BSA's campaigns and the RIAA's. First, BSA's members have always offered their products for sale to the public, through any channel that wants to sell them. Second, BSA's members are consumer-oriented; they try to develop products that respond to consumers' needs, and not, the reverse: focusing on what they want to sell to consumers. Third, because consumers can easily purchase BSA's members products, those who copy without paying are simply scofflaws. 'I think the fact that the public does not object to BSA's campaign proves my point [that]... people do not want things for free; they are willing to pay for them,' writes Patry. 'It should not be surprising that when consumers are not treated with respect, they react negatively. That's something the software industry learned long ago, and that's why people don't object to the BSA's enforcement campaign.'" -
Scientists Learn To Fabricate DNA Evidence
Hugh Pickens writes "The NY Times reports that it is possible to fabricate blood and saliva samples containing DNA from a person other than the donor, and even to construct a sample of DNA to match someone's profile without obtaining any tissue from that person — if you have access to their DNA profile in a database. This undermines the credibility of what has been considered the gold standard of proof in criminal cases. 'You can just engineer a crime scene,' said Dan Frumkin, lead author of the paper. 'Any biology undergraduate could perform this.' The scientists fabricated DNA samples in two ways. One requires a real, if tiny, DNA sample, perhaps from a strand of hair or a drinking cup. They amplified the tiny sample into a large quantity of DNA using a standard technique called whole genome amplification. The other technique relies on DNA profiles, stored in law enforcement databases as a series of numbers and letters corresponding to variations at 13 spots in a person's genome. The scientists cloned tiny DNA snippets representing the common variants at each spot, creating a library of such snippets. To prepare a phony DNA sample matching any profile, they just mixed the proper snippets together. Tania Simoncelli, science adviser to the American Civil Liberties Union, says the findings were worrisome. 'DNA is a lot easier to plant at a crime scene than fingerprints,' says Simoncelli. 'We're creating a criminal justice system that is increasingly relying on this technology.'" -
Production of Boeing 787 Dreamliner Delayed Again
Hugh Pickens writes "Boeing has discovered microscopic wrinkles in the skin of the 787's fuselage and has ordered Italian supplier Alenia Aeronautica to halt production of fuselage sections at a factory in Italy. 'In two areas on the fuselage, the structure doesn't have the long-term strength that we want,' says Boeing spokeswoman Lori Gunter. To repair the wrinkles, additional layers of carbon composite material are being added to a 787 at the South Carolina factory and twenty-two other planes must also be patched. Production of the 787 has been fraught with problems with ill-fitting parts, casting doubt on Boeing's strategy of relying on overseas suppliers to build big sections of the aircraft before assembling them at its facilities near Seattle. The 787, built for fuel efficiency from lightweight carbon composite parts, is a priority for Boeing as it struggles with dwindling orders amid the global recession. Customers had been expecting the first of the new jets in the first quarter of 2010 — nearly two years earlier than they will be delivered. The delays have cost Boeing credibility and billions of dollars in anticipated expenses and penalties. Orders for 72 planes have been canceled already this year, although Boeing still has confirmed orders for over 800 aircraft." -
BetOnSports Founder Pleads Guilty To Racketeering
Hugh Pickens writes "The founder of Internet- and telephone-based gambling operation BetOnSports has entered guilty pleas to three US charges, including a racketeering charge, and will forfeit $43.7 million to the US government as part of a plea agreement. Beginning in the mid- to late-1990s, Gary Kaplan set up businesses in Antigua and later Costa Rica to provide sports betting services to US residents through web sites and toll-free telephone numbers. Those numbers terminated in Houston or Miami, and were then forwarded to Costa Rica by satellite transmitter or fiber-optic cable. Some of Kaplan's web servers were located in Miami and were remotely controlled from Costa Rica. People became customers by depositing money in a BetOnSports account. By 2004, the BetOnSports organization's principal base of operations in Costa Rica employed about 1,700 people, had nearly one million registered customers and accepted more than 10 million sports bets. Now bankrupt, BetOnSports took in $1.25 billion in 2004, with 98 percent of that revenue coming from bets made through its web site by clients in the United States. 'Gary Kaplan made millions of dollars by making it too easy for people to gamble away their hard-earned money without having to leave their homes,' said FBI agent John Gillies. 'Today's guilty plea should have a lasting effect because Kaplan was not only the founder of BetOnSports, he was also one of the pioneers of illegal online gambling.'" -
Measuring Real Time Public Opinion With Twitter
Hugh Pickens writes "The NY Times reports that statisticians from the University of Vermont are hoping to harness the stream of messages flowing through Twitter to read public opinion and sentiment in real time. '"Twitter is a reflection of what people are interested in right now," says Peter Dodds, adding that the goal is to establish an index, akin to the Dow Jones industrial average, that can "give an overall sense of how a collective body of people are feeling at any given point in time.' Dodds says he and his colleagues are analyzing about 1,000 tweets each minute, or about a million a day, looking for trends in descriptive words and phrases that indicate moods and emotions. In addition, the two can monitor the public reaction to news or policy announcement and track it over time. The tool is still in its early stages, but eventually Dodds hopes that it could work similarly to Google Flu Trends, a Web tool that doubles as an early-warning system for flu outbreaks by detecting spikes in certain search terms. Since relationships and conversations are so intrinsic to how people communicate on Twitter, the researchers hope that observing how one user's mood is affected by another might shed some light on crowd behavior and emotional contagion. 'All of this data serves as a remote sensor of well-being,' Dodds says." -
Army Asks Its Personnel to Wikify Field Manuals
Hugh Pickens writes "The NY Times reports that the Army began encouraging its personnel — from the privates to the generals — to go online and collaboratively rewrite seven of the field manuals that give instructions on all aspects of Army life, using the same software behind Wikipedia. The goal, say the officers behind the effort, is to tap more experience and advice from battle-tested soldiers rather than relying on the specialists within the Army's array of colleges and research centers, who have traditionally written the manuals. 'For a couple hundred years, the Army has been writing doctrine in a particular way, and for a couple months, we have been doing it online in this wiki,' said Col. Charles J. Burnett, the director of the Army's Battle Command Knowledge System. 'The only ones who could write doctrine were the select few. Now, imagine the challenge in accepting that anybody can go on the wiki and make a change — that is a big challenge, culturally.' Under the three-month pilot program, the current version of each guide can be edited by anyone around the world who has been issued an ID card that allows access to the Army Internet system. Reaction so far from the rank and file has been tepid, but the brass is optimistic; even in an open-source world, soldiers still know how to take an order." -
EFF Says Burning Man Usurps Digital Rights
Hugh Pickens writes "In a few weeks, tens of thousands of creative people will make their yearly pilgrimage to Nevada's Black Rock desert for Burning Man, an annual art event and temporary community celebrating radical self expression, self-reliance, creativity and freedom, but EFF reports that the event's Terms and Conditions include 'a remarkable bit of legal sleight-of-hand.' As soon as 'any third party displays or disseminates' your photos or videos in a manner that the Burning Man Organization (BMO) doesn't like, those photos or videos become the property of the BMO. BMO's Terms and Conditions also limits your own rights to use your own photos and videos on any public websites obliging you to take down any photos to which BMO objects, for any reason; and forbidding you from allowing anyone else to reuse your photos. This 'we automatically own all your stuff' magic appears to be creative lawyering intended to allow the BMO to use the streamlined 'notice and takedown' process enshrined in the Digital Millennium Copyright Act (DMCA) to quickly remove photos from the Internet giving BMO the power of fast and easy online censorship. 'Burning Man strives to celebrate our individuality, creativity and free spirit,' writes Corynne McSherry. 'Unfortunately, the fine print on the tickets doesn't live up to that aspiration.'" -
Parents Baffled By Science Questions
Pickens writes "The BBC reports that four out of five parents living in the UK have been stumped by a science question posed by their children with the top three most-asked questions: 'Where do babies come from?', 'What makes a rainbow?' and 'Why is the sky blue?'. The survey was carried out to mark the launch of a new website by the Department for Business, Innovation and Skills called Science: So what? So everything." -
Database Error Costs Social Security Victims $500M
Hugh Pickens writes "The Washington Posts reports that the Social Security Administration has agreed to pay more than $500 million in back benefits to more than 80,000 recipients whose benefits were unfairly denied after they were flagged by a federal computer program designed to catch serious criminals. At issue is a 1996 law, which contained language later nicknamed the 'fleeing felon' provision, that said fugitives were ineligible to receive federal benefits. As part of its enforcement, the administration began searching computer databases to weed out people who were collecting benefits and had outstanding warrants. The searches captured dozens of criminals, including some wanted for homicide, but they also ensnared countless elderly and disabled people accused of relatively minor offenses such as shoplifting or writing bad checks and in some cases, the victims simply shared a name and a birth date with an offender." (Read more, below.) "The lead plaintiff in the class-action suit, Rosa Martinez, 52, of Redwood City, Calif., was cut off from her $870 monthly disability benefit check in January 2008 because the system had flagged an outstanding drug warrant in 1980 for a different Rosa Martinez from Miami. Officials said it is difficult to estimate how many social security recipients might be affected by the agreement but said the number is fewer than 1 percent nationally. 'What's remarkable about this case is thesheer number of individuals who were unfairly denied benefits and the size of the financial settlement they will receive,' said David H. Fry of Munger, Tolles & Olson, one of the pro bono attorneys who represented victims." -
A Standardized OS For Robots
Hugh Pickens writes "The New Scientist reports that at present, all robot software is designed uniquely, even for parts common to all robots but that could be about to change as roboticists have begun to think about what robots have in common and what aspects of their construction can be standardized, resulting in a basic operating system everyone can use. 'It's easier to build everything from the ground up right now because each team's requirements are so different,' says Anne-Marie Bourcier of Aldebaran Robotics but Bourcier sees this changing if robotics advances in a manner similar to personal computing where a common operating system allowed programmers without detailed knowledge of the underlying hardware and file systems to build new applications and build on the work of others. 'Robotics is at the stage where personal computing was about 30 years ago,' says Chad Jenkins of Brown University. 'But at some point we have to come together to use the same resources.' This desire has its roots in frustration, says Brian Gerkey of the robotics research firm Willow Garage. If someone is studying object recognition, they want to design better object-recognition algorithms, not write code to control the robot's wheels. "You know that those things have been done before, probably better," says Gerkey, who hopes to one day see a robot "app store" where a person could download a program for their robot and have it work as easily as an iPhone app." -
Are Information Technology's Glory Days Over?
Hugh Pickens writes "The NY Times reports that computer science students with the entrepreneurial spirit may want to look for a different major, because if Thomas M. Siebel, founder of Siebel Systems, is right, IT is a mature industry that will grow no faster than the larger economy, its glory days having ended in 2000. Addressing Stanford students in February as a guest of the engineering school, Siebel called attention to 20 sweet years from 1980 to 2000, when worldwide IT spending grew at a compounded annual growth rate of 17 percent. 'All you had to do was show up and not goof it up,' Siebel says. 'All ships were rising.' Since 2000, however, that rate has averaged only 3 percent. His explanation for the sharp decline is that 'the promise of the post-industrial society has been realized.' In Siebel's view, far larger opportunities are to be found in businesses that address needs in food, water, health care and energy. Though Silicon Valley was 'where the action was' when he finished graduate school, he says, 'if I were graduating today, I would get on a boat and I would get off in Shanghai.'" -
AOL Picking Up Journalists Shed By Conventional Media
Hugh Pickens writes "David Weir writes on Bnet that the thousands of journalists being let go from newspapers, magazines, and television networks have increasingly been showing up on AOL's payroll — over 1,500 in the last eighteen months — a number AOL expects to double or even triple over the coming year. 'Over time, talent is a fixed cost,' says Marty Moe, Senior Vice-President of AOL Media. 'You can syndicate it, distribute it as you scale. Furthermore, we are already the largest branded content company in the US, with an audience of 75 million domestic uniques. At our size, we can leverage the cost of our publishing and content management systems along with the talent and make the whole thing do-able on an advertising model.' Weir writes that AOL's turnaround started three years ago via the acquisition of Weblogs, Inc., and its set of branded verticals, including Engadget in technology, Autoblog covering the auto industry, and Joystiq covering gaming." -
Neuron Path Discovery May Change Our Conception of Itching
Hugh Pickens writes "Historically, many scientists have regarded itching as just a less intense version of pain, though decades spent searching for itch-specific nerve cells have been unfruitful. Now, Nature reports that neuroscientist Zhou-Feng Chen and his colleagues at Washington University in St. Louis, Missouri have found the first behavioral evidence that there are separate circuits of nerve cells to convey itchiness and pain, and their studies suggest that itch and pain signals are transmitted along different pathways in the spinal cord. 'Most people accept that there are specific, highly specialized neurons for sensations like taste,' says Chen. 'But for pain and itch this is much more controversial.'" (Continues below.) "Two years ago, Chen's group discovered that a cell-surface protein called the gastrin-releasing peptide receptor (GRPR) is important for sensing itchiness but not pain in mice. When Chen and his colleagues destroyed GRPR-bearing neurons by means of a cell toxin, the mice reacted to painful stimuli just like normal mice, licking themselves and flinching or jumping in response to heat, highly irritant chemicals and mechanical pressure. But when the researchers injected the animals with chemicals that normally cause scratching, such as histamine, they barely responded, and the greater the number of GRPR-expressing neurons destroyed, the more subdued was the scratching response." -
3D Images Reconstructed of 300M-Year-Old Spiders
Hugh Pickens writes "Scientists at Imperial College London have created detailed 3D computer models of two fossilized specimens of ancient creatures called Cryptomartus hindi and Eophrynus prestvicii, closely related to modern-day spiders. The researchers created their images by using a CT scanning device, which enabled them to take 3,000 X-rays of each fossil then compile them into precise 3D models, using custom-designed software. Both spiders roamed the Earth during the Carboniferous period, 359-299 million years ago, when life was emerging from the oceans to live on land. C. hindi's front pair of legs were angled toward the front, suggesting they were used to grapple with prey, an 'ambush predator' like the modern-day crab spider, lying in wait for prey to come close. 'Our models almost bring these ancient creatures back to life and it's really exciting to be able to look at them in such detail,' says researcher Russel Garwood, adding that the technique could be used to return to fossils that have previously been analyzed by conventional means. 'Our study helps build a picture of what was happening during this period early in the history of life on land.'" -
Adjustable-Focus Glasses Can Replace Bifocals
Hugh Pickens writes "The NY Times reports that inventor Stephen Kurtin has developed glasses with a mechanically adjustable focus that he believes can free nearly two billion people around the world from bifocals, trifocals and progressive lenses. Kurtin has spent almost 20 years on his quest to create a better pair of spectacles for people who suffer from presbyopia — the condition that affects almost everyone over the age of 40 as they progressively lose the ability to focus on close objects. The glasses have a tiny adjustable slider on the bridge of the frame that makes it possible to focus alternately on the page of a book, a computer screen, or a mountain range in the distance. 'For more than 140 years, adjustable focus has been recognized as the Holy Grail for presbyopes,' says Kurtin. 'It's a blazingly difficult problem.' Each 'lens' is actually a set of two lenses, one flexible and one firm. The flexible lens (near the eye) has a transparent, distensible membrane attached to a clear rigid surface. The pocket between them holds a small quantity of crystal-clear fluid. As you move the slider on the bridge, it pushes the fluid and alters the shape of the flexible lens." -
Experts Puzzled By Bright Spot On Venus
Hugh Pickens writes "BBC reports that astronomers are puzzled by a strange bright spot which has appeared in the clouds of Venus, first identified by US amateur astronomer Frank Melillo on 19 July and later confirmed by the European Space Agency's Venus Express spacecraft. 'I have seen bright spots before but this one is an exceptionally bright and quite intense area,' says Melillo. The bright spot has started to expand since its first appearance, being spread by winds in Venus' thick atmosphere. Scientists are unsure as to what is causing the spot. 'An eruption would have to be quite energetic to get a cloud this high,' said Dr. Sanjay Limaye of the University of Wisconsin. Furthermore, at a latitude of 50 degrees south, the spot lies outside the region of known volcanoes on Venus. Another potential source for the bright spot are charged particles from the Sun interacting with Venus' atmosphere. It's also possible that atmospheric turbulence may have caused bright material to become concentrated in one area. 'Right now, I think it's anybody's guess,' adds Limaye."
