Hugh Pickens writes "Space.com has a piece about changing theories of planet migration. The classic picture suggests that planets like Earth should have plummeted into the sun while they were still planetesimals, asteroid-sized building blocks that eventually collide to form full-fledged planets. 'Well, this contradicts basic observational evidence, like We. Are. Here,' says astronomer Moredecai-Mark Mac Low. Researchers investigating this discrepancy came up with a new model that explains how planets can migrate as they're forming and still avoid a fiery premature death. One problem with the classic view of planet formation and migration is that it assumes that the temperature of the protoplanetary disk around a star is constant across its whole span. It turns out that portions of the disk are opaque and so cannot cool quickly by radiating heat out to space. So in the new model, temperature differences in the space around the sun, 4.6 billion years ago, caused Earth to migrate outward as much as gravity was trying to pull it inward, and so the fledgling world found equilibrium in its current, habitable, orbit. 'We are trying to understand how planets interact with the gas disks from which they form as the disk evolves over its lifetime,' adds Mac Low. 'We show that the planetoids from which the Earth formed can survive their immersion in the gas disk without falling into the Sun.'"

Hugh Pickens writes "The NY Times has an interesting report on the iGeneration, born in the '90s and this decade, comparing them to the Net Generation, born in the 1980s. The Net Generation spend two hours a day talking on the phone and still use e-mail frequently while the iGeneration — conceivably their younger siblings — spends considerably more time texting than talking on the phone, pays less attention to television than the older group, and tends to communicate more over instant-messenger networks. 'People two, three or four years apart are having completely different experiences with technology,' says Lee Rainie, director of the Pew Research Center's Internet and American Life Project. 'College students scratch their heads at what their high school siblings are doing, and they scratch their heads at their younger siblings. It has sped up generational differences.' Dr. Larry Rosen, a professor of psychology at California State University, says that the iGeneration, unlike their older peers, expect an instant response from everyone they communicate with, and don't have the patience for anything less. 'They'll want their teachers and professors to respond to them immediately, and they will expect instantaneous access to everyone, because after all, that is the experience they have growing up,' says Rosen." Read below for another intra-generational wrinkle.
Another intra-generational gap is the iGeneration comfort in multi-tasking. Studies show that 16- to 18-year-olds perform seven tasks, on average, in their free time — like texting on the phone, sending instant messages, and checking Facebook while sitting in front of the television; while people in their early 20s can handle only six, and those in their 30s about five and a half. "That versatility is great when they're killing time, but will a younger generation be as focused at school and work as their forebears?" writes Brad Smith. "I worry that young people won't be able to summon the capacity to focus and concentrate when they need to," says Vicky Rideout, a vice president at the Kaiser Family Foundation.

Hugh Pickens writes "The Washington Post reports that Erroll Southers, President Obama's nominee to head the Transportation Security Administration, gave Congress misleading information about incidents in which he inappropriately accessed a federal database, possibly in violation of privacy laws. Southers accepted full responsibility for a 'grave error in judgment' when he accessed confidential criminal records twenty years ago about his then-estranged wife's new boyfriend. Southers's admission that he was involved in a questionable use of law enforcement background data has been a source of concern among civil libertarians, who believe the TSA performs a delicate balancing act in tapping into passenger information to find terrorists while also protecting citizens' privacy." "In his letter to key senators on November 20, Southers said he simply forgot the circumstances of the searches, which occurred in 1987 and 1988 after he grew worried about his wife and their son, who had begun living with the boyfriend. 'During a period of great personal turmoil, I made a serious error in judgment by using my official position with the FBI to resolve a personal problem,' Southers wrote. Civil liberties specialists say that the misuse of databases has been common among law enforcement authorities for many years, despite an array of local, state and federal prohibitions intended to protect personal information. Studies have found that police at every level examine records of celebrities, women they have met and political rivals. 'I am distressed by the inconsistencies between my recollection and the contemporaneous documents, but I assure you that the mistake was inadvertent, and that I have at all times taken full responsibility for what I know to have been a grave error in judgment,' Southers added."

Hugh Pickens writes "It seems like it was only yesterday when the entire world was abuzz about the looming catastrophe of Y2K that had us both panicked and prepared. Ten Years ago there were doomsday predictions that planes would fall from the sky and electric grids would go black, forced into obsolescence by the inability of computers to recognize the precise moment that 1999 rolled over to 2000 and for many it was a time to feel anxious about getting money out of bank accounts and fuel out of gas pumps. "Nobody really understood what impact it was going to have, when that clock rolled over and those digits went to zero. There was a lot of speculation they would reset back to 1900," says IT professional. Jake DeWoskin. The Y2K bug may have been IT's moment in the sun, but it also cast a long shadow in its wake as the years and months leading up to it were a hard slog for virtually everyone in IT, from project managers to programmers." "'People were scared for their jobs and their reputations," says CIO Dick Hudson, Staffers feared that if they were fired for failing to remedy Y2K problems, the stigma would prevent them from ever getting a job in IT again. "Then there was the fear that someone like Computerworld would report it, and it would be on the front page," Hudson adds. Although IT executives across the globe were confident that they had the problem licked, a nagging fear followed them right up until New Year's Eve. While most people were out celebrating the turn of the century, IT executives and their staffs were either monitoring events in the office or standing by at home. Afterwards came the recriminations and backlash as an estimated $100 billion was spent nationwide for problems that turned out to be minimal. Others says the nonevent was evidence the Y2K effort was done right. "It was a no-win situation," says Paul Ingevaldson. "People said, 'You IT guys made this big deal about Y2K, and it was no big deal. You oversold this. You cried wolf.' ""

Hugh Pickens writes "The NY Times reports that TSA special agents have served subpoenas to travel bloggers Steve Frischling and Chris Elliott demanding that they reveal who leaked a TSA directive outlining new screening measures that went into effect the same day as the Detroit airliner incident. Frischling said he met with two TSA special agents for about three hours and was forced to hand over his laptop computer after the agents threatened to interfere with his contract to write a blog for KLM Royal Dutch Airlines if he didn't cooperate and provide the name of the person who leaked the memo outlining new security measures that would be apparent to the traveling public. 'It literally showed up in my box,' Frischling told The Associated Press. 'I do not know who it came from.' Frischling says he provided the agents a signed statement to that effect. The leaked directive included measures such as screening at boarding gates, patting down the upper legs and torso, physically inspecting all travelers' belongings, looking carefully at syringes with powders and liquids, requiring that passengers remain in their seats one hour before landing, and disabling all onboard communications systems, including what is provided by the airline. In a December 29 posting on his blog, Elliott said he had told the TSA agents at his house that he would call his lawyer and get back to them."

Hugh Pickens writes "Neuroscientists Gary Lynch and Richard Granger have an interesting article in Discover Magazine about the Boskops, an extinct hominid that had big eyes, child-like faces, and forebrains roughly 50% larger than modern man indicating they may have had an average intelligence of around 150, making them geniuses among Homo sapiens. The combination of a large cranium and immature face would look decidedly unusual to modern eyes, but not entirely unfamiliar. Such faces peer out from the covers of countless science fiction books and are often attached to 'alien abductors' in movies. Naturalist Loren Eiseley wrote: 'Back there in the past, ten thousand years ago. The man of the future, with the big brain, the small teeth. He lived in Africa. His brain was bigger than your brain.' The history of evolutionary studies has been dogged by the almost irresistible idea that evolution leads to greater complexity, to animals that are more advanced than their predecessor, yet the existence of the Boskops argues otherwise — that humans with big brains, and perhaps great intelligence, occupied a substantial piece of southern Africa in the not very distant past, and that they eventually gave way to smaller-brained, possibly less advanced Homo sapiens — that is, ourselves. 'With 30 percent larger brains than ours now, we can readily calculate that a population with a mean brain size of 1,750 cc would be expected to have an average IQ of 149,' write Lynch and Granger. But why did they go extinct? 'Maybe all that thoughtfulness was of no particular survival value in 10,000 BC. Lacking the external hard drive of a literate society, the Boskops were unable to exploit the vast potential locked up in their expanded cortex,' write Lynch and Granger. 'They were born just a few millennia too soon.'"

Hugh Pickens writes "EFF reports that Cory Doctorow spoke to a crowd of about a hundred librarians, educators, publishers, authors, and students at the National Reading Summit on How to Destroy the Book and said that 'anyone who claims that readers can’t and won’t and shouldn’t own their books are bent on the destruction of the book, the destruction of publishing, and the destruction of authorship itself.' Doctorow says that for centuries, copyright has acknowledged that sacred connection between readers and their books and that when you own a book 'it’s yours to give away, yours to keep, yours to license or to borrow, to inherit or to be included in your safe for your children' and that 'the most important part of the experience of a book is knowing that it can be owned.'"

Hugh Pickens writes "Peter Kirwan has an interesting article in Wired UK on the emergence of software that automates the collection, evaluation, and even reporting of news events. Thomson Reuters, the world's largest news agency, has started moving down this path, courtesy of an intriguing product with the nondescript name NewsScope, a machine-readable news service designed for financial institutions that make their money from automated, event-driven trading. The latest iteration of NewsScope 'scans and automatically extracts critical pieces of information' from US corporate press releases, eliminating the 'manual processes' that have traditionally kept so many financial journalists in gainful employment. At Northwestern University, a group of computer science and journalism students have developed a program called Stats Monkey that uses statistical data to generate news reports on baseball games. Stats Monkey identifies the players who change the course of games, alongside specific turning points in the action. The rest of the process involves on-the-fly assembly of templated 'narrative arcs' to describe the action in a format recognizable as a news story. 'No doubt Kurt Cagle, editor of XMLToday.org, was engaging in a bit of provocation when he recently suggested that an intelligent agent might win a Pulitzer Prize by 2030,' writes Kirwin. 'Of course, it won't be the software that takes home the prize: it'll be the programmers who wrote the code in the first place, something that Joseph Pultizer could never have anticipated.'"

Hugh Pickens writes "The NY Times reports that German encryption expert Karsten Nohl says that he has deciphered and published the 21-year-old GSM algorithm, the secret code used to encrypt most of the world's digital mobile phone calls, in what he called an attempt to expose weaknesses in the security system used by about 3.5 billion of the 4.3 billion wireless connections across the globe. Others have cracked the A5/1 encryption technology used in GSM before, but their results have remained secret. 'This shows that existing GSM security is inadequate,' Nohl told about 600 people attending the Chaos Communication Congress. 'We are trying to push operators to adopt better security measures for mobile phone calls.' The GSM Association, the industry group based in London that devised the algorithm and represents wireless operators, called Mr. Nohl's efforts illegal and said they overstated the security threat to wireless calls. 'This is theoretically possible but practically unlikely,' says Claire Cranton, a GSM spokeswoman, noting that no one else had broken the code since its adoption. 'What he is doing would be illegal in Britain and the United States. To do this while supposedly being concerned about privacy is beyond me.' Simon Bransfield-Garth, the chief executive of Cellcrypt, says Nohl's efforts could put sophisticated mobile interception technology — limited to governments and intelligence agencies — within the reach of any reasonable well-funded criminal organization. 'This will reduce the time to break a GSM call from weeks to hours,' Bransfield-Garth says. 'We expect as this further develops it will be reduced to minutes.'"

Hugh Pickens writes "Steve Lohr writes in the NY Times that the country needs more 'cool' nerds — professionals with hybrid careers that combine computing with other fields like medicine, art, or journalism. Not enough young people are embracing computing, often because they are leery of being branded nerds. Educators and technologists say that two things need to change: the image of computing work, and computer science education in high schools. Today, introductory courses in computer science are too often focused merely on teaching students to use software like word processing and spreadsheet programs, says Janice C. Cuny, a program director at the National Science Foundation adding that the Advanced Placement curriculum concentrates too narrowly on programming. 'We're not showing and teaching kids the magic of computing,' Cuny says. The NSF is working to change this by developing a new introductory high school course in computer science and seeking to overhaul Advanced Placement courses as well. The NSF hopes to train 10,000 high school teachers in the modernized courses by 2015. Knowledge of computer science and computer programming is becoming a necessary skill for many professions, not only science and technology but also increasingly for marketing, advertising, journalism and the creative arts. 'We need to gain an understanding in the population that education in computer science is both extraordinarily important and extraordinarily interesting,' says Alfred Spector, vice president for research and special initiatives at Google. 'The fear is that if you pursue computer science, you will be stuck in a basement, writing code. That is absolutely not the reality.'"

Hugh Pickens writes "The Himalayas, home to some 10,000 glaciers, are the main source of replenishment to lakes, streams, and some of the continent's mightiest rivers, on which millions of people depend for their water supplies. Since the 1960s, the acreage covered by Himalayan glaciers has declined by more than 20 percent with a rate of warming twice the global average over the past 30 years. Now Live Science reports that tiny particles of pollution known as 'black carbon' — and not heat-trapping greenhouse gases — may be causing much of the rapid melting of glaciers in the Himalayas. 'Tibet's glaciers are retreating at an alarming rate,' says James Hansen, director of NASA's Goddard Institute for Space Studies in New York City. 'Black soot is probably responsible for as much as half of the glacial melt, and greenhouse gases are responsible for the rest.' The circulation of the atmosphere in the region causes much of the soot-laden air to 'pile up' against the Himalayas. The soot mixes with other dust from nearby deserts, creating a massive brown cloud visible from space that absorbs incoming solar radiation. As this layer heats up in the Himalayan foothills, it rises and enhances the seasonal northward flow of humid monsoon winds, forcing moisture and hot air up the slopes of the mountain range."

Hugh Pickens writes "She was at sea for 221 days, alone, often in dangerous places, and usually out of touch. Most of the time she was out of contact underwater, moving slowly up and down to depths of 600 feet, safe from ships, nets, and storms. Her predecessor had disappeared on a similar trip, probably killed by a shark. 'She was a hero,' says Rutgers University oceanographer Scott Glenn after retrieving Scarlet Knight, the 7-foot-9-inch submersible robot from the stormy Atlantic off western Spain. An engineer working for the company that made the submersible said, 'We think this will just be a precursor, like Lindbergh's trip across the Atlantic. In a decade we think it will be commonplace to have roving fleets of these gliders making transoceanic trips.' The people responsible for building, funding, and flying Scarlet hope the end of the robot's successful voyage will mark a new beginning in ocean and climate research. From its position at each surfacing — when the glider surfaced and called home via an Iridium telephone parked in its tail — researchers could calculate the net effect of currents deep and shallow. After surface currents were measured, the scientists could then make inferences about what was happening deeper in the water column. Scarlet called home to upload data to researchers three times a day. 'When we have hundreds of them, or thousands of them, it will revolutionize how we can observe the oceans,' says Jerry L. Miller, a senior policy analyst at the White House Office of Science and Technology Policy, who accompanied the research team to Spain."

Hugh Pickens writes "The NY Times reports that auto enthusiasts across the country are dismayed by the news that General Motors is planning to shut down Saab, the Swedish carmaker it bought two decades ago, after a deal to sell it fell apart. Even with its modest and steadily declining sales, Saab, an acronym for Svenska Aeroplan Aktiebolaget, or Swedish Airplane Company, long stood out as a powerful brand in spite of itself. 'It wasn't designed to be a fashion statement,' says Ron Pinelli, president of Autodata, which tracks industry statistics. 'It was designed to provide transportation under miserable weather conditions.' Many Saab owners consider the brand's glory days to be the 1980s, when Americans began buying cars again after a recession and energy crisis. 'The cars were communicative,' says Pinelli. 'They didn't try to numb the experience like cars do today.' The cars had odd touches and appealed to those who appreciate the unconventional. Swedish engineers assumed drivers would be wearing gloves, so they designed big buttons for the dashboard. Though the cars were compact, with long hoods and short rear ends, there was plenty of headroom inside. Now Saab, a brand that once had one of the clearest identities in the industry, seems headed for extinction just as automakers are searching for more distinctive designs to help set them apart. 'It's a shame that Saab is a victim,' adds Pinelli."

Hugh Pickens writes "Nature reports that data collected on the timing of attacks and number of casualties from more than 54,000 events across nine insurgent wars, including those fought in Iraq between 2003 and 2008 and in Sierra Leone between 1994 and 2003, suggest that insurgencies have a common underlying pattern that may allow the timing of attacks and the number of casualties to be predicted. By plotting the distribution of the frequency and size of events, the team found that insurgent wars follow an approximate power law, in which the frequency of attacks decreases with increasing attack size to the power of 2.5. This means that for any insurgent war, an attack with 10 casualties is 316 times more likely to occur than one with 100 casualties (316 is 10 to the power of 2.5). 'We found that the way in which humans do insurgent wars — that is, the number of casualties and the timing of events — is universal,' says team leader Neil Johnson, a physicist at the University of Miami in Florida. 'This changes the way we think insurgency works.' To explain what was driving this common pattern, the researchers created a mathematical model which assumes that insurgent groups form and fragment when they sense danger, and strike in well-timed bursts to maximize their media exposure. Johnson is now working to predict how the insurgency in Afghanistan might respond to the influx of foreign troops recently announced by US President Barack Obama. 'We do observe a complicated pattern that has to do with the way humans do violence in some collective way,' adds Johnson."

Hugh Pickens writes "BBC reports that Markus Haering's company had been working with the authorities in Basel, Switzerland to try to convert the heat in deep-seated rocks into electricity, but the project was suspended in 2006 when drilling triggered earthquakes, one of them with a magnitude of 3.4, leading Haering's company to pay out $9M in damages. Haering's team planned to drill a series of holes penetrating up to 3 miles (4.8 km) underground with water being pumped onto rocks with a temperature of more than 195C. Basel's location on top of a fault line – the upper Rhine trench – had been deliberately chosen because the heat was closer to the Earth's surface. A risk assessment has since shown that the prospect of further quakes is too high to continue drilling in the city. Haering faces up to five years in prison if the judge finds he intentionally damaged property. Haering has admitted the 3.4 magnitude earthquake was stronger than he had expected and that his team 'had very little knowledge of seismicity' before starting to drill, but called the quakes 'a learning process for everyone involved.' Despite Haering's trial, the Swiss appetite for geothermal projects has not diminished. Engineers are beginning preliminary drilling in Zurich to see whether that area was suitable for a similar scheme, and St. Gallen, in eastern Switzerland, plans to start work on its own geothermal project next year. Drilling efforts are being closely watched in the US, where the energy department is sponsoring more than 120 geothermal energy projects in several states."

Hugh Pickens writes "Consumer Reports says that most of the time, extended service contracts aren't worth the additional dollars. But the Washington Post reports that purchases of extended warranties are up 10 percent over last year, according to the Service Contract Industry Council, a trade group. Consumers 'tend to be more risk-averse and are less willing to absorb the cost of an unexpected product repair or replacement,' says Timothy Meenan, the council's executive director. Mark Kotkin, director of survey research for CR, acknowledges that there are instances when the extended warranty can be worth it. 'We recommend getting one for the Apple computer,' Kotkin says. 'The tech support that comes with the extended warranty is great. Without it, the tech support is skimpy.' Another product where extended warranties may be of use are giant television sets, where few manufacturers will come to your home to make warranty repairs. Extended service contracts for big screen TVs often offer in-home repair, says Meenan, who once shipped a Sony TV to the service center for repair under the manufacturer's warranty. 'They fixed it and brought it back 45 days later.'"

Hugh Pickens writes "Currently, the National Institutes of Health require that research funded by its grants be made available to the public online at no charge within 12 months of publication. Now the Office of Science and Technology Policy in the Executive Office of the President is launching a 'Public Access Policy Forum' to determine whether this policy should be extended to other science agencies and, if so, how it should be implemented. 'The NIH model has a variety of features that can be evaluated, and there are other ways to offer the public enhanced access to peer-reviewed scholarly publications,' OSTP says in the request for information. 'The best models may [be] influenced by agency mission, the culture and rate of scientific development of the discipline, funding to develop archival capabilities, and research funding mechanisms.' The OSTP will conduct an interactive, online discussion that will focus on three major questions: Should this policy be extended to other science agencies and, if so, how it should be implemented? In what format should the data be submitted in order to make it easy to search and retrieve information? What are the best mechanisms to ensure compliance? 'It's very encouraging to see the Obama Administration focus on ensuring public access to the results of taxpayer-funded research [reg. required] as a key way to maximize our collective investment in science,' says Heather Joseph, executive director of the Scholarly Publishing and Academic Resources Coalition."

Hugh Pickens writes "The NY Times reports that Florida's Judicial Ethics Advisory Committee has found in a recent opinion that judges and lawyers can no longer be Facebook friends. The committee says that when judges 'friend' lawyers who may appear before them, it creates the appearance of a conflict of interest, since it 'reasonably conveys to others the impression that these lawyer "friends" are in a special position to influence the judge.' Stephen Gillers, a legal ethics expert at New York University, says the Florida rule goes too far. 'In my view, they are being hypersensitive because in the case of a truly close friendship between a judge and a lawyer involved in a case, the other side can simply seek to disqualify the judge. Judges do not "drop out of society when they become judges," Gillers says. "The people who were their friends before they went on the bench remained their friends, and many of them were lawyers." Still, legal sycophants can take heart: lawyers can declare themselves Facebook "fans" of judges, the committee says, "as long as the judge or committee controlling the site cannot accept or reject the lawyer's listing of himself or herself on the site."'"

Hugh Pickens writes "The Telegraph reports that scientists have created the first artificial meat by extracting cells from the muscle of a live pig and putting them in a broth of other animal products where the cells then multiplied to create muscle tissue. Described as soggy pork, researchers believe that it can be turned into something like steak if they can find a way to 'exercise' the muscle and while no one has yet tasted the artificial meat, researchers believe the breakthrough could lead to sausages and other processed products being made from laboratory meat in as little as five years' time. '"What we have at the moment is rather like wasted muscle tissue. We need to find ways of improving it by training it and stretching it, but we will get there," says Mark Post, professor of physiology at Eindhoven University. "You could take the meat from one animal and create the volume of meat previously provided by a million animals." Animal rights group Peta has welcomed the laboratory-grown meat, announcing that "as far as we're concerned, if meat is no longer a piece of a dead animal there's no ethical objection while the Vegetarian Society remained skeptical. "The big question is how could you guarantee you were eating artificial flesh rather than flesh from an animal that had been slaughtered. It would be very difficult to label and identify in a way that people would trust.""

Hugh Pickens writes "Numerous high-tech devices have been proposed to help ships cope with piracy on the high seas. Now a company has developed a ship-borne launching device that fires a net or coiled rope into the path of pirate vessels using compressed air with a range of up to a range of 400m. The payload net or rope, which has a parachute attached to the end, will unravel and lay out across the surface of the water so that as the pirate boat travels through the water its propeller shaft will pick up the line and become entangled. 'With the trials and testing we've done, it has taken us some 45 minutes to cut and disentangle the line from the propeller itself,' says Jonathan Delf. 'Within that time of course, the target ship is on its way and hopefully help has arrived in the form of naval forces or helicopter support.' The system can be fired up to five times off just a cylinder of air like a simple scuba tank." The video mentions that the device can also fire a payload of golf balls. The systems have recently been sold to "several large shipping companies that travel near the oil-rich Nigerian Delta, which, like the Somalian coast, is rife with piracy."

Hugh Pickens writes "Edmund Conway has an interesting article in the Telegraph where he analyzes where the money goes when you buy a complex electronic device marked 'Made in China,' and why a developed economy doesn't need a trade surplus in order to survive. For his example, Conway chooses a 30GB video iPod 'manufactured' in China in 2006. Each iPod, sold in the US for $299, provides China with an export value of about $150, but as it turns out, Chinese producers really only 'earned' around $4 on each unit. 'China, you see, is really just the place where most of the other components that go inside the iPod are shipped and assembled.' Conway says that when you work out the overall US balance of payments, it shows that most of the cash for high tech inventions has flowed back to the United States as a direct result of the intellectual property companies own in their products. 'While the iPod is manufactured offshore and has a global roster of suppliers, the greatest benefits from this innovation go to Apple, an American company, with predominantly American employees and stockholders who reap the benefits,' writes Conway. 'As long as the US market remains dynamic, with innovative firms and risk-taking entrepreneurs, global innovation should continue to create value for American investors and well-paid jobs for knowledge workers. But if those companies get complacent or lose focus, there are plenty of foreign competitors ready to take their places.'"

Hugh Pickens writes "Nicholas Carr has an interesting analysis of Rupert Murdoch's threat to de-list News Corp's stories from Google and Microsoft's eager offer to make Bing Murdoch's exclusive search engine for its content. Carr writes that newspapers are caught in a classic Prisoner's Dilemma with Google because Google's search engine 'prevents them from making decent money online — by massively fragmenting traffic, by undermining brand power, and by turning news stories into fungible commodities.' If any single newspaper opts out of Google, their competitors will pick up the traffic they lose. There is only one way that newspapers can break out of the prison — if a critical mass of newspapers opt out of Google's search engine simultaneously, they would suddenly gain substantial market power. Murdoch may have been signaling to other newspapers that 'we'll opt out if you'll opt out,' positioning himself as the would-be ringleader of a massive jailbreak, without actually risking a jailbreak himself. There are signs that Murdoch's signal is working, with reports that the publishers of the Denver Post and the Dallas Morning News are now also considering blocking Google. In the meantime, Steve Ballmer is more than happy to play along with Murdoch because although a deal with News Corps would reduce the basic profitability of Microsoft's search business, it would inflict far more damage on Google than on Microsoft."

Hugh Pickens writes "BBC reports that astronomers have invented a game to help uncover the basis of galactic collisions, showing players images of colliding galaxies and asking them to match those to simulations. These galactic mergers could be the key to why the Universe contains a mixture of different galaxies — some with trailing spiral arms, others more like compact balls of stars. Astronomers say that humans are 'much better than computers' at spotting the patterns and similarities. 'The strength of the game is that it takes results from many people,' says Dr Chris Lintott from Oxford University, one of the members of the Galaxy Zoo team. The developers describe the game as a 'cosmic fruit machine' (i.e., slot machine). The game shows players one real galaxy image and, on command, eight randomly selected simulations pop into the 'slot'" surrounding that image. The aim is for players to choose the simulations that look most similar to the real galaxy and take those through to the next round to examine them further. The simulated images show the different aspects of galaxy formation, so as people play, they will generate data that will help astronomers understand these collisions. 'These collisions take millions of years to unfold,' says Anthony Holincheck, a graduate student at George Mason University and another member of the team. 'All we get from the Universe is a single snapshot of each one. [With] simulations, we will be able to watch each cosmic car crash unfold in the computer.'"

Hugh Pickens writes "The NY Times reports that Amazon and Wal-Mart are waging a price war for the future of online retailing that is spreading through product areas like books, movies, toys, and electronics. The tussle began last month over which company had the lowest prices on the most anticipated new books and DVDs this fall, but has now spread to select video game consoles, mobile phones, even to the humble Easy-Bake Oven. 'It's not about the prices of books and movies anymore. There is a bigger battle being fought,' said Fiona Dias, executive vice president at GSI Commerce, which manages the Web sites of large retailers. 'The price-sniping by Wal-Mart is part of a greater strategic plan. They are just not going to cede their business to Amazon.' Wal-Mart, with $405 billion in sales last year, dominates by offering affordable prices to Middle America in its 4,000 stores, while Amazon, with $20 billion in sales, caters mostly to affluent urbanites who would rather not push around a cart. But Amazon is expanding its slice of the retail pie at an alarming rate — its sales shot up 28 percent in the third quarter of this year; and sales in Amazon's electronics and general merchandise business are up 44 percent. 'We have to put our foot down and refuse to let them grow more powerful,' says Dias. 'I applaud Wal-Mart. It's about time multichannel retailers stood up and refused to let their business go away.'"

Pickens writes "The NY Times reports that a program to detect plutonium or uranium in shipping containers has stalled because the United States has run out of helium 3, a crucial raw material needed to build the 1,300 to 1,400 machines to be deployed in ports around the world to thwart terrorists who might try to deliver a nuclear bomb to a big city by stashing it in one of the millions of containers that enter the United States every year. Helium 3 is an unusual form of the element that is formed when tritium, an ingredient of hydrogen bombs, decays — but the government mostly stopped making tritium in 1989 after accumulating a substantial stockpile of Helium 3 as a byproduct of maintaining nuclear weapons. 'I have not heard any explanation of why this was not entirely foreseeable,' says Representative Brad Miller, chairman of a House subcommittee that is investigating the problem. Helium 3 is not hazardous or even chemically reactive, and it is not the only material that can be used for neutron detection. The Homeland Security Department has older equipment that can look for radioactivity, but it does not differentiate well between bomb fuel and innocuous materials that naturally emit radiation like cat litter, ceramic tiles and bananas — and sounds false alarms more often. In a letter to President Obama, Miller called the shortage 'a national crisis' and said the price had jumped to $2,000 a liter from $100 in the last few years. With continuing concern that Al Qaida or other terrorists will try to smuggle a nuclear weapon into the United States, Congress has mandated that, by 2012, all containers bound for the US be inspected overseas."

Hugh Pickens writes "The Financial Times reports that Microsoft is in discussions to pay Rupert Murdoch's News Corp, owner of newspapers ranging from the Wall Street Journal of the US to The Sun of the UK, to 'de-index' its news websites from Google, setting the scene for a search engine battle that could offer a ray of light to the newspaper industry. Microsoft is desperate to catch Google in search, and, after five years and hundreds of millions of dollars of losses, Bing, launched in June, marks its most ambitious attempt yet. Microsoft's interest is being interpreted as a direct assault on Google because it puts pressure on the search engine to start paying for content. 'This is all about Microsoft hurting Google's margins,' said the web publisher who is familiar with the plan. 'It's easy to believe that [Microsoft] may spew senseless riches into publishers' pockets, radically distorting the news market, just to spite Google,' writes Rob Beschizza at BoingBoing. 'Murdoch could be wringing cash out of a market he knows is doomed to implosion or assimilation. And he doesn't even have to be an evil genius, either; he just has to be smarter than Steve Ballmer.'"

Hugh Pickens writes "Increasingly, the military is deploying unmanned aerial vehicles, or UAVs, as eyes in the sky to scan the ground for targets and threats, especially for missions that are too dangerous for manned aircraft. Now Live Science reports that a new robotic spy plane called 'Ion Tiger' will harness alternative energy to make it more covert and longer lasting than battery-powered or engine-powered UAVs. A 550-watt, 0.75 horsepower hydrogen fuel cell will power the Ion Tiger with four times the efficiency of a comparable internal combustion engine and seven times the energy of the equivalent weight of batteries. When Ion Tiger took flight in October, it exceeded any demonstration of electrically powered flight so far, flying 23 hours and 17 minutes. 'And it carried a 5 lbs. payload to boot — enough to carry, say, a day-and-night camera,' says researcher Karen Swider-Lyons, head of the alternative energy section at the Naval Research Laboratory in Washington. 'No one has come close to flying 24 hours with a significant payload before.' Another big advantage is the Ion Tiger's reduced noise, heat and emissions. 'Think about lawnmowers or chainsaws — they're really loud,' says Swider-Lyons. 'It's hard to spy on people when they know you're there, so you had to fly them at high altitudes to keep them from being heard.'"

Hugh Pickens writes "The World Health Organization says that there were 'early signs of a peak' in swine flu activity in parts of the Northern Hemisphere, including the US. The American College Health Association, which surveys more than 250 colleges with more than three million students, said new flu cases had dropped 27 percent in the week ending on November 13th from the week before, the first drop since school resumed in the fall. Nonetheless, Dr. Anne Schuchat, the director of vaccination and respiratory disease at the CDC, chose her words carefully. 'We are in better shape today than we were a couple of weeks ago,' she says. 'I wish I knew if we had hit the peak. Even if a peak has occurred, half the people who are going to get sick haven't gotten sick yet.' Privately, federal health officials say they fear that if they concede the flu has peaked, Americans will become complacent and lose interest in getting vaccinated, increasing the chances of another wave. However, Dr. Lone Simonsen, a former CDC epidemiologist, says she expects a third wave in December or January, possibly beginning in the South again. Based on death rates in New York City and in Scandinavia, Simonsen argues that both 1918 and 1957 had mild spring waves followed by two stronger waves, one in fall and one in midwinter, adding that in the pandemic of 1889, the bulk of the deaths occurred in the third wave. 'If people think it's going away, they can think again.'"

Hugh Pickens writes "The Christian Science Monitor reports that a federal judge has ruled that the Army Corps of Engineers — and thus the US government — is liable for a big chunk of the damage caused when hurricane Katrina pushed ashore on August 29, 2005 by failing to stop the natural widening of the Mississippi River Gulf Outlet canal (aka Mr. Go) causing it to eventually bump up against the shore of Lake Borgne, on the city's east side. 'It is the court's opinion that the negligence of the corps, in this instance by failing to maintain the MR-GO properly, was not policy, but insouciance, myopia, and shortsightedness,' wrote US District Court Judge Stanwood Duval. Judge Duval said he believed it was the failure to shore up the outlet that 'doomed the channel to grow to two to three times its design width' allowing waves on Lake Borgne to enter the Mr. Go and travel into the east side of the city, battering the levees to a degree to which they were not designed. 'One of the greatest catastrophes in the history of the US' was both predictable and preventable, testified veteran Louisiana geologist Sherwood Gagliano, a former Corps consultant."

Hugh Pickens writes "The advantages of RISC are well known — simplifying the CPU core by reducing the complexity of the instruction set allows faster speeds, more registers, and pipelining to provide the appearance of single-cycle execution. Al Williams writes in Dr Dobbs about taking RISC to its logical conclusion by designing a functional computer called One-Der with only a single simple instruction — a 32-bit Transfer Triggered Architecture (TTA) CPU that operates at roughly 10 MIPS. 'When I tell this story in person, people are usually squirming with the inevitable question: What's the one instruction?' writes Williams. 'It turns out there's several ways to construct a single instruction CPU, but the method I had stumbled on does everything via a move instruction (hence the name, "Transfer Triggered Architecture").' The CPU is implemented on a Field Programmable Gate Array (FPGA) device and the prototype works on a 'Spartan 3 Starter Board' with an XS3C1000 device available from Digilent that has the equivalent of about 1,000,000 logic gates, costing between $100 and $200. 'Applications that can benefit from custom instruction in hardware — things like digital signal processing, for example — are ideal for One-Der since you can implement parts of your algorithm in hardware and then easily integrate those parts with the CPU.'"

Hugh Pickens writes "The Telegraph reports that 4,000 microscopic worms were onboard Space Shuttle Atlantis when it launched today. Their mission: to help experts in human physiology understand more about what triggers the body to build and lose muscle. The worms are bound for the Japanese Experiment Module 'Kibo' on the International Space Station, where they will experience the same weightless conditions which can cause dramatic muscle loss, one of the major health concerns for astronauts. 'If we can identify what causes the body to react in certain ways in space we establish new pathways for research back on earth,' says Dr. Nathaniel Szewczyk."

Pickens writes "The Telegraph reports that the Vatican's Pontifical Academy of Sciences is holding its first ever conference on alien life, the discovery of which would have profound implications for the Catholic Church. For centuries, theologians have argued over what the existence of life elsewhere in the universe would mean for the Church. Among other things, extremely alien-looking aliens would be hard to fit with the idea that God 'made man in his own image' and Jesus Christ's role as savior would be confused; would other worlds have their own Christ-figures, or would Earth's Christ be universal? Just as the Church eventually made accommodations after Copernicus and Galileo showed that the Earth was not the center of the universe, and when it belatedly accepted the truth of Darwin's theory of evolution, Catholic leaders say that alien life can be aligned with the Bible's teachings. 'Just as a multiplicity of creatures exists on Earth, so there could be other beings, also intelligent, created by God,' says Father Jose Funes, a Jesuit astronomer at the Vatican Observatory and one of the organizers of the conference. Others do not agree. 'If you look back at the history of Christian debate on this, it divides into two camps. There are those that believe that it is human destiny to bring salvation to the aliens, and those who believe in multiple incarnations,' says Paul Davies, a theoretical physicist. 'The multiple incarnations is a heresy in Catholicism.'"

Hugh Pickens writes "Stephen Williams reports in the NY Times that the app recreating some of the Commodore's seminal retro games, including Le Mans, Dragons Den and Jupiter Lander, has been re-issued after being pulled in September. The app features SID sound emulation, auto-save to continue where you left off, and a realistic joystick with a beautifully crafted C64 keyboard. Apple originally rejected the program for violating the SDK agreement, which dictates that 'no interpreted code may be downloaded and used in an Application except for code that is interpreted and run by Apple's Published APIs and built-in interpreter(s).' After disabling the controversial feature, Apple published the app in September, but days later it was pulled and the developer was asked to remove, rather than just disable, the BASIC interpreter from the program, which would have allowed unscrupulous users to run unlicensed, emulated code on the iPhone or iPod Touch. 'The road was bumpy, but we remained persistent and made the changes Apple was looking for. Ultimately, BASIC has been removed for this release; however, we hope that working with Apple further will allow us to re-enable it,' the company wrote on its blog."

Pickens writes "Tom Bradley reports in PC World that the new Motorola Droid smartphone will cost users $199.99 with a 2-year contract, with an additional $30 per month for the mandatory 'unlimited' data plan that has a monthly cap of 5Gb. Verizon will charge $50 for each additional gigabyte over the 5Gb limit on the unlimited data plan. Verizon has confirmed that tethering will cost another $30 per month for an additional unlimited data plan that is also limited to 5Gb. If you want tethering you will pay $60 above and beyond the monthly contract for service for an 'unlimited' 10Gb of data per month, and if you plan on connecting with an Microsoft Exchange email account you have to pay another $15 a month. 'Verizon seems to be doing everything it can to make the Droid as unappealing as possible by nickel and diming customers so that actually using it is not cost-effective,' writes Bradley. 'After all of the hype around Verizon's marketing efforts, and generally favorable reviews of the Motorola Droid, users that rush out to get the new device may be in for a shock.' Droid users will have to wait until sometime in 2010 for tethering. 'That service is on our schedule for next year,' says Verizon spokeswoman Brenda Raney. The delay is because 'the service has to be tested on the phone so until we know it works, we don't offer the service. It is not uncommon for us to introduce the phone and continue to test the service and offer it later.'"

Hugh Pickens writes "CBS reports on 60 minutes that a massive two-day power outage in Brazil's Espirito Santo State affecting more than three million people in 2007, and another, smaller event in three cities north of Rio de Janeiro in January 2005, were perpetrated by hackers manipulating control systems. Former Chief of US National Intelligence Retired Adm. Mike McConnell says that the 'United States is not prepared for such an attack' and believes it could happen in America. 'If I were an attacker and wanted to do strategic damage to the United States, I would either take the cold of winter or the heat of summer,' says McConnell, 'I would probably sack electric power on the US East Coast, maybe the West Coast and attempt to cause a cascading effect.' Congressman Jim Langevin says that US power companies need to be forced to deal with the issue after they told Congress they would take steps to defend their operations but did not follow up. 'They admit that they misled Congress. The private sector has different priorities than we do in providing security. Their bottom line is about profits,' says Langevin. 'We need to change their motivation so that when see vulnerability like this, we can require them to fix it.' McConnell adds that a similar attack to the one in Brazil is poised to take place on US soil and that it may take some horrific event to get the country focused on shoring up cyber security. 'If the power grid was taken off line in the middle of winter and it caused people to suffer and die, that would galvanize the nation. I hope we don't get there.'"

Hugh Pickens writes "The Telegraph reports that the Japanese trawler Diasan Shinsho-maru has capsized off the coast of China, as its three-man crew dragged their net through a swarm of giant jellyfish (which can grow up to six feet in diameter and travel in packs) and tried to haul up a net that was too heavy. The crew was thrown into the sea when the vessel capsized, but the three men were rescued by another trawler. Relatively little is known about Nomura's jellyfish, such as why some years see thousands of the creatures floating across the Sea of Japan on the Tsushima Current, but last year there were virtually no sightings. In 2007, there were 15,500 reports of damage to fishing equipment caused by the creatures. Experts believe that one contributing factor to the jellyfish becoming more frequent visitors to Japanese waters may be a decline in the number of predators, which include sea turtles and certain species of fish. 'Jellies have likely swum and swarmed in our seas for over 600 million years,' says scientist Monty Graham of the Dauphin Island Sea Lab in Alabama. 'When conditions are right, jelly swarms can form quickly. They appear to do this for sexual reproduction.'"

Hugh Pickens writes "The Telegraph reports that Professor Carol Tilley, a professor of library and information science at the University of Illinois, says that comics are just as sophisticated as other forms of reading, children benefit from reading them at least as much as they do from reading other kinds of books, and that there is evidence that comics increase children's vocabulary and instill a love of reading. 'A lot of the criticism of comics and comic books come from people who think that kids are just looking at the pictures and not putting them together with the words,' says Tilley. 'But you could easily make some of the same criticisms of picture books – that kids are just looking at pictures, and not at the words.' Tilley says that some of the condescension toward comics as a medium may come from the connotations that the name itself evokes but that the distinct comic book aesthetic — frames, thought and speech bubbles, motion lines, to name a few — has been co-opted by children's books, creating a hybrid format."

Hugh Pickens writes "Science Daily reports findings from a new study which suggest that infants begin picking up elements of what will be their first language in the womb, long before their first babble or coo, and are able to memorize sounds from the external world by the last trimester of pregnancy, with a particular sensitivity to melody contour in both music and language. Newborns prefer their mother's voice over other voices and perceive the emotional content of messages conveyed via intonation contours in maternal speech (a.k.a. 'motherese'). 'The dramatic finding of this study is that not only are human neonates capable of producing different cry melodies, but they prefer to produce those melody patterns that are typical for the ambient language they have heard during their fetal life, within the last trimester of gestation,' said Kathleen Wermke of the University of Würzburg in Germany. Wermke's team recorded and analyzed the cries of 60 healthy newborns, 30 born into French-speaking families and 30 born into German-speaking families, when they were three to five days old. The recordings of 2,500 cries as mothers changed babies' diapers, readied babies for feeding or otherwise interacted with the youngsters show an extremely early impact of native language, with analysis revealing clear differences in the shape of the newborns' cry melodies, based on their mother tongue."

Hugh Pickens writes "Evidence that the smell of fear is real was uncovered by US scientists last year who studied the underarm secretions of 20 terrified novice skydivers and found that people appear to respond unconsciously to the sweat smell of a frightened person. Now the Telegraph reports that researchers hope a 'fear detector' will make it possible to identify individuals at check points who are up to no good. 'The challenge lies in the characterization and identification of the specific chemical that gives away the signature of human fear, especially the fear in relation to criminal acts,' says Professor Tong Tun at City University London, who leads the team developing security sensor systems that can detect the human fear pheromone. The project will look at potential obstacles to the device, such as the effects of perfume and the variances in pheromone production and if the initial 18-month feasibility study is successful, the first detectors could be developed in the next two to three years. 'I do not see any particular reason why similar sensor techniques cannot be expanded to identify human smells by race, age or gender to build a profile of a criminal during or after an incident,' Tong added."

Hugh Pickens writes "Researchers at the University of Rochester believe that a 35-mile rift in the desert of Ethiopia will likely become a new ocean in a million years or so, connecting the Red Sea with the Gulf of Aden. Using newly gathered seismic data, researchers have reconstructed how the rift tore open along its entire 35-mile length in just days. Dabbahu, a volcano at the northern end of the rift, erupted first, then magma pushed up through the middle of the rift area and began 'unzipping' the rift in both directions. 'We know that seafloor ridges are created by a similar intrusion of magma into a rift, but we never knew that a huge length of the ridge could break open at once like this,' says Cindy Ebinger, professor of earth and environmental sciences at the University of Rochester. The results show that highly active volcanic boundaries along the edges of tectonic ocean plates may suddenly break apart in large sections, instead of in bits, as the leading theory had previously held. The sudden large-scale events pose a much more serious hazard to populations living near the rift than would several smaller events."

Hugh Pickens writes "With news organizations struggling and newsroom jobs disappearing, each week brings new calls from writers and editors who believe their employers should save themselves by charging for Internet access. However, in an interesting turnabout, the NY Times reports that Saul Friedman, a journalist for more than 50 years and a columnist for Newsday since 1996, announced last week he was quitting after Newsday decided that non-subscribers to Newsday's print edition will have to pay $5 a week to see much of the site, making it one of the few newspapers in the country to take such a plunge. 'My column has been popular around the country, but now it was really going to be impossible for people outside Long Island to read it,' he says. Friedman, who is 80, said he would continue to write about older people for the site 'Time Goes By.' 'One of the reasons why the NY Times eventually did away with its old "paywall" was that its big name columnists started complaining that fewer and fewer people were reading them,' writes Mike Masnick at Techdirt. 'Newspapers who decide to put up a paywall may find that their best reporters decide to go elsewhere, knowing that locking up their own content isn't a good thing in terms of career advancement.'"

Hugh Pickens writes "Yale University researchers believe that if evolutionary pressures of sexual selection and reproductive fitness continue for another 10 generations, the trends detected in their study may mean that the average woman in 2409 AD will be 2 cm shorter, 1 kg heavier, will bear her first child five months earlier, and enter menopause 10 months later. 'There is this idea that because medicine has been so good at reducing mortality rates, that means that natural selection is no longer operating in humans,' says Stephen Stearns of Yale University. 'That's just plain false.' Stearns and his team studied the medical histories of 14,000 residents of the Massachusetts town of Framingham, using medical data from a study going back to 1948 spanning three generations, and found that shorter, heavier women had more children than lighter, taller ones. Women with lower blood pressure and cholesterol were also more likely to have large families as were women who gave birth early or had a late menopause. More importantly, these traits are then passed on to their daughters, who also, on average, had more children. The study has not determined why these factors are linked to reproductive success, but it is likely that they indicate genetic, rather than environmental, effects. 'The evolution that's going on in the Framingham women is like average rates of evolution measured in other plants and animals,' says Stearns. 'These results place humans in the medium-to-slow end of the range of rates observed for other living things.'"

Pickens writes "Science Daily News reports that human missions to Mars and all other long-term space flights might be compromised by disease, first because space travel appears to weaken astronauts' immune systems; and second, because it increases the virulence and growth of microbes. 'When people think of space travel, often the vast distances are what come to mind first,' says Jean-Pol Frippiat from Nancy-University in France, 'but even after we figure out a way to cover these distances in a reasonable amount of time, we still need to figure out how astronauts are going to overcome disease and sickness.' Frippiat says studies show that immune systems of both people and animals in space flight conditions are significantly weaker than their grounded counterparts and that common pathogens such as Salmonella, E. coli and Staphylococcus reproduce more rapidly in space flight conditions, leading to increased risk of contamination, colonization and serious infection."

Hugh Pickens sends in a Wall Street Journal report that Chinese banks will provide $1.5B to a consortium of Chinese and American companies to build a 600-megawatt wind farm in West Texas, using turbines made in China. The wind farm will be built on 36,000 acres, and will use 240 2.5-megawatt turbines, providing enough power to meet the electrical needs of around 150,000 American homes. The project will be the first instance of a Chinese manufacturer exporting wind turbines to the United States. China aims to be the front-runner in wind- and solar-power generation "The Obama administration is hoping a shift to renewable energy will inject new life into the US manufacturing base and provide high-paying jobs, making up for losses in other sectors. But while the US has poured money into renewable energy through tax credits and other subsidies, China has positioned itself to reap many of the benefits by ramping up its export machine."

Hugh Pickens writes "The Washington Post reports that US newspaper circulation has hit its lowest level in seven decades, as papers across the country lost 10.6 percent of their paying readers from April through September, compared with a year earlier. Online, newspapers are still a success — but only in readership, not in profit. Ads on newspaper Internet sites sell for pennies on the dollar compared with ads in their ink-on-paper cousins. 'Newspapers have ceased to be a mass medium by any stretch of the imagination,' says Alan D. Mutter, a former journalist and cable television executive who now consults and writes a blog called Reflections of a Newsosaur. According to Mutter only 13 percent of Americans, or about 39 million, now buy a daily newspaper, down from 31 percent in 1940. 'Publishers who think their businesses are going to live or die according to the number of bellybuttons they can deliver probably will see their businesses die,' writes Mutter. 'The smart ones will get busy on Plan B, assuming there is a Plan B and it's not already too late.' Almost without exception, the papers that lost the least readers or even gained readership are the nation's smallest daily newspapers which tend to focus almost all of their limited resources on highly local news that is not covered by larger outside organizations and have a lock on local ad markets."

Hugh Pickens writes "The NY Times reports that two Northwest Airlines pilots who flew about 110 miles past their destination to the skies over Wisconsin as more than a dozen air-traffic controllers in three locations tried to get the plane's attention had taken out their personal laptops in the cockpit, a violation of airline policy, so the first officer could tutor the captain in a new scheduling system put in place by Delta Air Lines, which acquired Northwest last fall. 'Both said they lost track of time,' said an interim report from the National Transportation Safety Board countering theories in aviation circles that the two pilots might have fallen asleep or were arguing in the cockpit. 'Using laptops or engaging in activity unrelated to the pilots' command of the aircraft during flight,' said a statement from Delta Airlines, 'is strictly against the airline's flight deck policies and violations of that policy will result in termination.' Industry executives and analysts said the pilots' behavior was a striking lapse for such veteran airmen who have a total of 31,000 flying hours of experience between them. In the case of Flight 188, 'Neither pilot was aware of the airplane's position until a flight attendant called about five minutes before they were scheduled to land and asked what was their estimated time of arrival,' the interim report said."

Hugh Pickens writes "Medical News Daily reports that researchers have found signs of enhanced neural stimulation in parts of the brain that control decision-making and reasoning when they scanned the brains of middle-aged and older first-time Internet users after only seven days of performing Internet searches. 'We found that for older people with minimal experience, performing Internet searches for even a relatively short period of time can change brain activity patterns and enhance function,' says Dr Gary Small, a professor of psychiatry at the Semel Institute for Neuroscience and Human Behavior at UCLA. At the start of the study, the participants performed Internet searches while the researchers took fMRI scans of their brains to track changes in blood flow in the brain and record subtle changes in neural activity. After practicing searching the Internet for 7 days over 2 weeks at home, the brains of the Internet novices showed activity in the same regions as before, but this time there was new activity in the middle frontal gyrus and inferior frontal gyrus, the parts of the brain that are important for working memory and decision-making. 'You can exercise your mind by using the Internet, but it depends on how it's used,' adds Small. 'If you get hooked on gambling or eBay shopping, that may not be positive.'"

Hugh Pickens writes "The NY Times reports that as the number of swine flu cases grows to levels unprecedented for this time of year, health officials predict a shortfall in the supply of swine flu vaccine. Forty-three children have died from swine flu since August 30 — about the same number that usually die in an entire flu season.' These are very sobering statistics,' says Dr. Anne Schuchat, the director of the National Center for Immunization and Respiratory Diseases, 'and unfortunately they are likely to increase.' Projections of the supply of swine flu vaccine have widely varied. During the summer, health officials said 120 million doses would be ready in October but later dropped the estimate to 40 million doses. Now officials expect only 28 million to 30 million doses, adding that the exact number is impossible to predict and could change daily as vaccine manufacturers report that production was behind schedule. 'Vaccine production for influenza is pretty complex,' says Schuchat explaining the delay, 'and the complex process this year is taking a bit longer than we had hoped.' Schuchat warned parents with sick children to be alert for signs that medical attention is required including not eating well, difficulties breathing, and turning blue or gray. A particularly important sign is when children start to get better, then have a relapse, usually a sign that pneumonia is developing, and immediate treatment should be sought."

Hugh Pickens writes "The president of the Maldives and 11 ministers, decked out in scuba gear, held a cabinet meeting 4m underwater to highlight the threat of global warming to the low-lying Indian Ocean nation. While officials said the event itself was light-hearted, the idea is to focus on the plight of the Maldives, where rising sea levels threaten to make the nation uninhabitable by the end of the century. President Mohamed Nasheed and his cabinet spent half an hour on the sea bed, communicating with white boards and hand signals and signed a document calling for global cuts in carbon emissions. The Maldives has already begun to divert a portion of the country's billion-dollar annual tourist revenue to buy a new homeland as an insurance policy against climate change that threatens to turn the 300,000 islanders into environmental refugees. Emerging out of the water, a dripping President Nasheed removed his mask to answer questions from reporters and photographers crowded around on the shore. 'We are trying to send a message to the world about what is happening and what would happen to the Maldives if climate change isn't checked,' he said, bobbing around in the water with his team of ministers. 'If the Maldives is not saved, today we do not feel there is much chance for the rest of the world.'"

Hugh Pickens writes "The Los Angeles Times reports that California regulators are poised to pass the nation's first ban on energy-hungry big-screen televisions just as they did with refrigerators, air conditioners and dozens of other products since the 1970s. 'We would not propose TV efficiency standards if we thought there was any evidence in the record that they will hurt the economy,' said Commissioner Julia Levin, who has been in charge of the two-year rule-making procedure. 'This will actually save consumers money and help the California economy grow and create new clean, sustainable jobs.' California's estimated 35 million TVs and related electronic devices account for about 10% of all household electricity consumption, but manufacturers quickly are coming up with new technologies that are making even 50-inch-screen models much more economical to operate. Sets with screens of up to 58 inches would have until the start of 2011 to comply with a minimum efficiency standard, with more stringent rules being introduced two years later. If all TVs met state standards, California could avoid the $600-million cost of building a natural-gas-fired power plant, says Ken Rider, a commission staff engineer. Switching to more-efficient TVs could have an estimated net benefit to the state of $8.1 billion, the commission staff reported."
