Urine Passes NASA Taste Test
Ponca City, We love you writes "Astronauts flying aboard space shuttle Endeavour are delivering a device to the International Space Station that may leave you wondering if NASA is taking recycling too far. Among the ship's cargo is a water regeneration system that distills, filters, ionizes, and oxidizes wastewater — including urine — into fresh water for drinking or, as one astronaut puts it, 'will make yesterday's coffee into today's coffee.' The US space agency spent $250M for the water recycling equipment but with the space shuttles due to retire in two years, NASA needed to make sure the station crew would have a good supply of fresh water. The Environmental Control and Life Support Systems uses a purification process called vapor compression distillation: urine is boiled until the water in it turns to steam. In space, there's an additional challenge: steam doesn't rise, so the entire distillation system is spun to create artificial gravity to separate the steam from the brine. The water has been thoroughly tested on Earth, including blind taste tests that pitted recycled urine with similarly treated tap water. 'Some people may think it's downright disgusting, but if it's done correctly, you process water that's purer than what you drink here on Earth,' said Endeavour astronaut Heidemarie Stefanyshyn-Piper." -
The Greatest Scientific Hoaxes?
Ponca City, We love you writes "The New Scientist has an amusing story about the seven greatest scientific hoaxes of all time. Of course, there have been serious cases of scientific fraud, such as the stem cell researchers recently found guilty of falsifying data, and the South Korean cloning fraud, but the hoaxes selected point more to human gullibility than malevolence and include the Piltdown Man (constructed from a medieval human cranium); a ten-foot "petrified man" dug up on a small farm in Cardiff; fossils 'found' in Wurzburg, Germany depicting comets, moons and suns, Alan Sokal's paper loaded with nonsensical jargon that was accepted by the journal Social Text; the claim of the Upas tree on the island of Java so poisonous that it killed everything within a 15-mile radius; and Johann Heinrich Cohausen's claim of an elixir produced by collecting the breath of young women in bottles that produced immortality. Our favorite: BBC's broadcast in 1957 about the spaghetti tree in Switzerland that showed a family harvesting pasta that hung from the branches of the tree. After watching the program, hundreds of people phoned in asking how they could grow their own tree but, alas, the program turned out to be an April Fools' Day joke." What massive scientific hoaxes/jokes have other people witnessed? -
Google Founders Buy Fighter Jet
Ponca City, We love you writes "The NY Times reports that H211 LLC, a company controlled by Google's top executives, including billionaire founders Larry Page and Sergey Brin, appears to have added to its fleet a Dornier Alpha Jet, a light jet attack and advanced trainer aircraft manufactured by Dornier of Germany and Dassault-Breguet of France. The 1982 Alpha-Jet seats two and was originally used by European air forces, but is now being sold relatively cheaply to civilians. The jet has landing rights at Moffett Field, the NASA-operated airfield that is a stone's throw from the Google campus. It is not clear who exactly flies the fighter jet, although Google chief executive Eric Schmidt is an avid pilot. If the top Googlers indeed own the fighter jet, they would be following in the footsteps of Oracle chief executive Larry Ellison, who has owned several aircraft, including fighter jets." -
Banjo Used In Brain Surgery
Ponca City, We love you writes "Legendary bluegrass musician Eddie Adcock has undergone brain surgery to treat a hand tremor, playing his banjo throughout to test the success of the procedure. Adcock suffers from essential tremor, a condition where there is a continuing deterioration in areas of the brain that control movement, causing a tremor that usually appears when the person tries to act or move. Deep brain stimulation can be used to treat the movement difficulties of both Parkinson's and essential tremor by sinking an electrode into the thalamus, a deep brain area that is part of the motor loop — a circuit that helps coordinate movement. Surgeons placed electrodes in Adcock's brain and fitted a pacemaker in his chest, which delivers a small current that shuts down the region of his brain causing the tremors. The most sensible thing to do was to tweak the system while Adcock was playing the banjo to optimize the effect for the thing that's most important to him." -
Simple Device Claimed To Boost Fuel Efficiency By Up To 20%
Ponca City, We love you writes "Temple University physics professor Rongjia Tao has developed a simple device that could dramatically improve fuel efficiency in automobiles by as much as 20 percent. The device, attached to the fuel line of a car's engine near the fuel injector, creates an electric field that thins fuel, reducing its viscosity so that smaller droplets are injected into the engine. Because combustion starts at the droplet surface, smaller droplets lead to cleaner and more efficient combustion. Six months of road testing in a diesel-powered Mercedes-Benz automobile showed an increase from 32 miles per gallon to 38 mpg, a 20 percent boost, and a 12-15 percent gain in city driving. 'We expect the device will have wide applications on all types of internal combustion engines, present ones and future ones,' Tao wrote in the study published in Energy & Fuels. 'This discovery promises to significantly improve fuel efficiency in all types of internal combustion engine powered vehicles and at the same time will have far-reaching effects in reducing pollution of our environment,' says Larry F. Lemanski, Senior Vice President for Research and Strategic Initiatives at Temple." -
New Rifle Tech Offers Variable Muzzle Speed
Ponca City, We love you writes "A gun that fires variable-speed bullets that can be set to kill, wound, or just inflict a bruise is being built by a Lund and Company Invention, a toy design studio that makes toy rockets powered by burning hydrogen obtained by electrolyzing water. The company is being funded by the US Army to adapt the technology to fire bullets instead. The new weapon, called the Variable Velocity Weapon System or VWS, lets the soldier use the same rifle for crowd control and combat, by altering the muzzle velocity. It could be loaded with 'rubber bullets' designed only to deliver blunt impacts on a person, full-speed lethal rounds, or projectiles somewhere between the two. Bruce Lund, the company's CEO, says the gun works by mixing a liquid or gaseous fuel with air in a combustion chamber behind the bullet. This determines the explosive capability of the propellant and consequently the velocity of the bullet. 'Projectile velocity varies from non-lethal at 10 meters, to lethal at 100 meters or more, as desired,' says Lund. The existing VWS design is a .50 caliber (12.7 mm) rifle weapon, but Lund says the technology can be scaled to any size, 'handgun to Howitzer.'" -
There's a Sucker Converted Every Minute
Ponca City, We love you writes "Once the US converts from analog to digital broadcasting next February, those who receive their signals over the air will need a converter box for older, non-digital models. Government-approved converter boxes sell for $60 or less and a government-issued $40 rebate coupon is available for the asking but that hasn't stopped companies like the Ohio-based Universal TechTronics from offering supposedly free converter boxes. The gimmick: the box is free, as long as you pay $88 for a five-year warranty, plus $9.30 shipping. Universal TechTronics seems to specialize in 'high-tech' products of questionable value, marketing the Cool Surge portable air cooler, 'a work of engineering genius from the China coast so advanced that no windows, vents, or freon are needed' that uses the same energy as a 60-watt light bulb. It works by blowing a stream of air over two ice packs that you have previously frozen in your freezer. What's the best tech scam you've heard of lately?" -
Road Rage Linked To Automobile Bumper Stickers
Ponca City, We Love You sends news of a study by Colorado State University psychologist William Szlemko that recorded whether people had added seat covers, bumper stickers, special paint jobs, stereos, or plastic dashboard toys to their cars. Szlemko found a link between road rage and the number of personalized items on or in people's vehicles. "The number of territory markers predicted road rage better than vehicle value, condition, or any of the things that we normally associate with aggressive driving,' says Szlemko. What's more, only the number of bumper stickers, and not their content, predicted road rage... Szlemko suggests that this territoriality may encourage road rage because drivers are simultaneously in a private space (their car) and a public one (the road). 'We think they are forgetting that the public road is not theirs, and are exhibiting territorial behavior that normally would only be acceptable in personal space,' the researcher says. -
Leaning Tower of Pisa Secure For 300 More Years
Ponca City, We Love You writes "The tower of Pisa began to lean five years after its construction began, in 1178, and by 1990 it had tilted more than four meters off its true vertical. Conservationists estimated that the entire 14,500-ton structure would collapse 'some time between 2030 and 2040.' Now the Leaning Tower of Pisa has been stabilized and declared safe for at least another three centuries. The stabilization, which cost $30M, was accomplished by anchoring it to cables and lead counterweights, while 70 tons of soil were removed from the side away from the lean, and cement was injected into the ground to relieve the pressure. The tilt has now returned to where it was in the early 19th century. Nicholas Shrady, author of Tilt: A Skewed History of the Tower of Pisa, says that the tower was destined to lean from the outset because it was built on 'what is essentially a former bog.' Shrady adds that the tower previously came close to collapsing in 1838, 1934, and 1995. (The commission convened in 1990 to study the tower's stability was the 17th such.) Although Galileo Galilei is said to have dropped cannon balls from the tower in a gravity experiment, Shrady says the myth is the result of 'the overripe imagination of Galileo's secretary and first biographer, Vincenzo Viviani.'" -
The Military Plans To Regrow Body Parts
Ponca City, We Love You writes "The Department of Defense has announced the creation of the Armed Forces Institute of Regenerative Medicine to 'harness stem cell research and technology... to reconstruct new skin, muscles and tendons, and even ears, noses and fingers.' The government is budgeting $250 million in public and private money for the project's first five years, and the NIH and three universities will be on the team. The military has been working on regrowing lost body parts using extracellular matrices and scientists in labs have grown blood vessels, livers, bladders, breast implants, and meat and are already growing a new ear for a badly burned Marine using stem cells from his own body. Army Surgeon General Eric Schoomaker explained that our bodies systematically generate liver cells and bone marrow and that this ability can be redirected through 'the right kind of stimulation.' The general cited animals like salamanders that can regrow lost tails or limbs. 'Why can't a mammal do the same thing?' he asked." -
Mysterious Sound Waves Can Destroy Rockets
Ponca City, We love you writes "Scientists believe that powerful and unstable sound waves, created by energy supplied by the combustion process, were the cause of rocket failures in several US and Russian rockets. They have also observed these mysterious oscillations in other propulsion and power-generating systems such as missiles and gas turbines. Now, researchers at the Georgia Institute of Technology have developed a liquid rocket engine simulator and imaging techniques to help demystify the cause of these explosive sound waves and bring scientists a little closer to being able to understand and prevent them. The team was able to clearly demonstrate that the phenomenon manifests itself in the form of spinning acoustic waves that gain destructive power as they rotate around the rocket's combustion chamber at a rate of 5,000 revolutions per second. Researchers developed a low-pressure combustor to simulate larger rocket engines then used a very-high-speed camera with fiber optic probes to observe the formation and behavior of excited spinning sound waves within the engine. 'This is a very troublesome phenomenon in rockets,' said Professor Ben Zinn. 'These spinning acoustic oscillations destroy engines without anyone fully understanding how these waves are formed. Visualizing this phenomenon brings us a step closer to understanding it.'" -
Blizzard Sues Creator of WoW Bot
Ponca City, We Love You writes "Blizzard, the makers of World of Warcraft, are suing Michael Donnelly, the creator of the MMO Glider program, which performs key tasks in the game automatically. Blizzard says the software bot infringes the company's copyright and potentially damages the game. 'Blizzard's designs expectations are frustrated, and resources are allocated unevenly, when bots are introduced into the WoW universe, because bots spend far more time in-game than an ordinary player would and consume resources the entire time,' Blizzard wrote in its legal submission to the court. More than 100,000 copies of the tool have been sold while more than 10 million people around the world play Warcraft. Donnelly says his tool does not infringe Blizzard's copyright because no 'copy' of the Warcraft game client software is ever made. The two parties are now awaiting a summary judgment in the case." -
A Virus that Attacks Brain Cancer
Ponca City, We Love You writes "In the past few years, scientists have looked to viruses as potential allies in fighting cancer. Now researchers at Yale University have found a virus in the same family as rabies that effectively kills an aggressive form of human brain cancer in mice. Using time-lapse laser imaging, the team watched vesicular stomatitis virus (VSV) rapidly home in on brain tumors, selectively killing cancerous cells in its path, while leaving healthy tissue intact. 'A metastasizing tumor is fairly mobile, and a surgeon's knife can't get out all of the cells,' says Anthony Van den Pol, lead researcher and professor of neurosurgery and neurobiology at Yale. 'A virus might be able to do that, because as a virus kills a tumor cell, it could also replicate, and you could end up with a therapy that's self-amplifying.' It's not yet clear why VSV is such an effective tumor killer, although Van den Pol has several theories. One possible explanation may involve a tumor's weak vascular system. Vessels that supply blood to tumors tend to be leaky, allowing a virus traveling through the bloodstream to cross an otherwise impermeable barrier into the brain, directly into a tumor." -
Researchers Develop Self-Cleaning Clothes
Ponca City, We Love You writes "Researchers at Monash University, in Australia, have found a process to coat natural fibers such as wool, silk, and hemp that will automatically remove food, grime, and even red-wine stains by coating their fibers with titanium dioxide nanocrystals, which break down food and dirt in sunlight. Titanium dioxide is a strong photocatalyst and in the presence of ultraviolet light and water vapor, it forms hydroxyl radicals, which oxidize, or decompose, organic matter. "These nanocrystals cannot decompose wool and are harmless to skin," says organic chemist and nanomaterials researcher Walid Daoud. Titanium dioxide can also destroy pathogens such as bacteria in the presence of sunlight by breaking down the cell walls of the microorganisms making self-cleaning fabrics especially useful in hospitals and other medical settings." -
Do Gamers Enjoy Dying in First-Person-Shooters?
Ponca City, We Love You writes "Brandon Erickson has an interesting post about an experiment on players' emotional reactions to killing and being killed in a first-person shooters (FPS) with a group of students who played James Bond 007: Nightfire while their facial expressions and physiological activity were tracked and recorded moment-to-moment via electrodes and various other monitoring equipment. The study found that "death of the player's own character...appear[s] to increase some aspects of positive emotion." The authors believe this may result from the temporary "relief from engagement" brought about by character death. "Part of this has to do with the intriguing aesthetic question of precisely how the first-person-shooter represents the player after the moment of death," says Clive Thompson. "This sudden switch in camera angle — from first person to third person — is, in essence, a classic out-of-body experience, of exactly the sort people describe in near-death experiences. And much like real-life near-death experiences, it tends to suffuse me with a curiously zen-like feeling." An abstract of the original article, "The psychophysiology of James Bond: Phasic emotional responses to violent video game events" is available on the web." Obnoxiously this alleged scholarly research is not available for free, so we'll just have to speculate wildly what it says based on the abstract. -
Military Grounds Stealth Bomber Fleet
Ponca City, We Love You writes "America's entire B-2 stealth bomber fleet, which has played a crucial part in all major US conflicts since 1989, has been grounded after one of the jets crashed near a military base in Guam. The crash — the first involving the B-2 — was the most expensive single aircraft accident in history. (The planes cost $1.2B each.) Officials assume the crash was caused by either mechanical failure or human error, but have grounded all B-2s to ensure there is not some fundamental fault developing in the 21-strong fleet. The crash occurred Saturday morning local time as the B-2 was taking off from Andersen Air Force base on Guam, a US territory south of Japan. An Air Force spokesman said, 'The cause of crash is unknown, pending an investigation. The pilots had ejected safely — no serious injuries. One is mobile, one is still in the hospital under observation.'" -
Scientists Find Believing Can Be Seeing
Ponca City, We Love You writes "Scientists at University College London have found the link between what we expect to see, and what our brain tells us we actually saw revealing that the context surrounding what we see is all important — sometimes overriding the evidence gathered by our eyes and even causing us to imagine things which aren't really there. A vague background context is more influential and helps us to fill in more blanks than a bright, well-defined context. This may explain why we are prone to 'see' imaginary shapes in the shadows when the light is poor. "Illusionists have been alive to this phenomenon for years," said Professor Zhaoping. "When you see them throw a ball into the air, followed by a second ball, and then a third ball which 'magically' disappears, you wonder how they did it. In truth, there's often no third ball — it's just our brain being deceived by the context, telling us that we really did see three balls launched into the air, one after the other." The original research paper is available on PLOS, the open-access, peer-reviewed journal." -
Obsolete Technical Skills
Ponca City, We Love You writes "Robert Scoble had an interesting post on his blog a few days ago on obsolete technical skills — 'things we used to know that no longer are very useful to us.' Scoble's initial list included dialing a rotary phone, using carbon paper to make copies, and changing the gas mixture on your car's carburetor. The list has now been expanded into a wiki with a much larger list of these obsolete skills that includes resolving IRQ conflicts on a mother board, assembly language programming, and stacking a quarter on an arcade game to indicate you have next. We're invited to contribute more." -
iPhones Produced in China Smuggled Right Back in
Ponca City, We Love You writes "Factories in China produce iPhones that are exported to the United States and Europe and then smuggled right back in helping explain why Apple says it sold about 3.7 million iPhones last year while only 2.3 million are actually registered in the United States and Europe. For Apple, the booming overseas market for iPhones is a sign of its marketing prowess but also a blow to Apple's business model, costing the company as much as $1 billion over the next three years, according to some analysts. Since negotiations between Apple and China Mobile, the world's biggest mobile-phone service operator with more than 350 million subscribers, broke down last month, the official release of the iPhone in China has been stalled producing a thriving gray market. Copycat models are another possible threat to Apple in China. Not long after the iPhone was released, research and development teams in China were taking it apart, trying to copy or steal the design and software for use in iPhone knockoffs, or iClones and some people who have used the clones say they are sophisticated and have many functions that mimic the iPhone. "A lot of people here want to get an iPhone," says Shanghai lawyer Conlyn Chan." -
Space Shuttle Secrets Stolen For China
Ponca City, We Love You writes "The Department of Justice has announced the indictment of former Boeing engineer Dongfan Chung on charges of economic espionage in the theft of company trade secrets relating to the Space Shuttle, the C-17 military transport aircraft, and the Delta IV rocket. Chung is a native of China and a naturalized US citizen. According to the indictment, Chinese aviation industry representatives began sending Chung 'tasking' letters as early as 1979. Over the years, the letters directed Chung to collect specific technological information, including data related to the Space Shuttle and various military and civilian aircraft. Chung allegedly responded in one letter indicating a desire to contribute to the 'motherland,' the DOJ said. It was not immediately clear how much, if any, damage the alleged espionage did to US national security but DOJ officials said the cases reflect the determination of the Chinese government to penetrate US intelligence and obtain vital national defense secrets. 'Today's prosecution demonstrates that foreign spying remains a serious threat in the post-Cold War world,' said Kenneth L. Wainstein, Assistant Attorney General for National Security" -
Name the New Gamma-Ray Space Telescope
Ponca City, We Love You writes "NASA announced last week that members of the general public will have a chance to suggest a new name for the cutting edge Gamma-ray Large Area Space Telescope, otherwise known as GLAST, before it launches in mid-2008. NASA wants a name that will capture the excitement of GLAST's mission and call attention to gamma-ray and high-energy astronomy. 'We are looking for something memorable to commemorate this spectacular new astronomy mission,' said Alan Stern, associate administrator for Science at NASA Headquarters in Washington. 'We hope someone will come up with a name that is catchy, easy to say and will help make the satellite and its mission a topic of dinner table and classroom discussion.' The period for submitting names closes on March 31, 2008. Participants must include a statement of 25 words or less about why their suggestion would be a strong name for the mission." -
Toddlers May Learn Language By Data Mining
Ponca City, We Love You writes "Toddlers' brains can effortlessly do what the most powerful computers with the most sophisticated software cannot: learn language simply by hearing it used. A ground-breaking new theory postulates that young children are able to learn large groups of words rapidly by data-mining. Researchers Linda Smith and Chen Yu attempted to teach 28 children, 12 to 14 months old, six words by showing them two objects at a time on a computer monitor while two pre-recorded words were read to them. No information was given regarding which word went with which image. After viewing various combinations of words and images, however, the children were surprisingly successful at figuring out which word went with which picture. Yu and Smith say it's possible that the more words tots hear, and the more information available for any individual word, the better their brains can begin simultaneously ruling out and putting together word-object pairings, thus learning what's what. Yu says if they can identify key factors involved in this form of learning and how it can be manipulated, they might be able to make learning languages easier for children and adults. Understanding children's learning mechanisms could also further machine learning." -
Space Spotters Track Secret Satellites
Ponca City, We Love You writes "When government officials announced last month that a top-secret spy satellite would come falling out of the sky they said little about the satellite itself. They didn't need to. Spotters equipped with little more than a pair of binoculars, a stop watch and star charts, had already uncovered some of the deepest of the government's expensive secrets and shared them on the Internet. Thousands of people form the spotter community. Many look for historical relics of the early space age, working from publicly available orbital information. Still others are drawn to the secretive world of spy satellites, with about a dozen hobbyists doing most of the observing. When a new spy satellite is launched the hobbyists will collaborate on sightings around the world to determine its orbit, and even guess at its function. They often share their information on their web site, satobs.org." -
The Physics of Football
Ponca City, We Love You writes "There will be a program on applied physics and real time strategy that you might want to watch on television today. Conservation of momentum during elastic and inelastic collisions is one aspect on which to focus as players tackle their opponents. It is of critical importance that the Patriots bring down New York's huge and powerful running back, 6-foot-4, 265-pound Brandon Jacobs. An average-size NFL defensive back's mass combined with his speed — on average, 4.56 seconds for the 40-yard dash — can produce up to 1600 pounds of tackling force. A tackle with half a ton of force may sound like a crippling blow, but the body can handle twice that amount because the player's equipment spreads out the incoming energy, lessening its severity." Nanotech specialists from Cornell have developed their own take on the "physics" of the Super Bowl by creating the world's smallest trophy, which will be awarded today to a contestant who best explains an aspect of football physics. Just some food for thought while you watch the game on your brand new HD television, though you'd better not be watching it in a church. -
Yahoo Bid shows Microsoft on the Ropes
Ponca City, We Love You writes "One day after the announcement of Microsoft's plan to buy Yahoo, there is an interesting piece from the NY Times analyzing the reasons behind Microsoft's bid and proposing that the bid is a tacit, and difficult, admission that Microsoft did not get its online business right and that online losses continue to mount while Google makes billions in profit. Microsoft "finds itself in a battle where improving its search algorithms and online ad software is not going to be enough," writes the Times. With the Yahoo bid Microsoft is trying to buy a big enough share of the market to be a credible alternative to Google with online advertisers. "This shows just how worried Microsoft is by Google," says David B. Yoffie. "Microsoft has faced competitive threats before, but none with the size, strength, profitability and momentum of Google."" -
AT&T's Plan to Play Internet Cop
Ponca City, We Love You writes "Tim Wu has an interesting (and funny) article on Slate that says that AT&T's recent proposal to examine all the traffic it carries for potential violations of US intellectual property laws is not just bad but corporate seppuku bad. At present AT&T is shielded by a federal law they wrote themselves that provides they have no liability for 'Transitory Digital Network Communications' — content AT&T carries over the Internet. To maintain that immunity, AT&T must transmit data 'without selection of the material by the service provider' and 'without modification of its content' but if AT&T gets into the business of choosing what content travels over its network, it runs the serious risk of losing its all-important immunity. 'As the world's largest gatekeeper,' Wu writes, 'AT&T would immediately become the world's largest target for copyright infringement lawsuits.' ATT's new strategy 'exposes it to so much potential liability that adopting it would arguably violate AT&T's fiduciary duty to its shareholders,' concludes Wu." -
Filming an Invasion Without Extras
Ponca City, We Love You writes "Kevin Kelly has an interesting blog post on how a World War II D-Day invasion was staged in a few days with four guys and a video camera using batches of smaller crowds replicated computationally to produce very convincing non-repeating huge crowds. Filmmakers first used computer generated crowds about ten years ago and the technique became well known in the Lord of the Rings trilogy but now crowds can be generated from no crowds at all — just a couple of people. 'What's new is that the new camera/apps are steadily becoming like a word processor — both pros and amateurs use the same one,' says Kelly. 'The same gear needed to make a good film is today generally available to amateurs — which was not so even a decade ago. Film making gear is approaching a convergence between professional and amateur, so that what counts in artistry and inventiveness.'" -
"Cone of Silence" Possible Say Scientists
Ponca City, We Love You writes "The 'Cone of Silence,' once a staple of 1960's television shows, is now possible say scientists at Duke University who first demonstrated a working 'cloak of invisibility' that works at microwave frequencies in 2006. Such a cloak designed for audio frequencies might hide submarines in the ocean from detection by sonar or improve the acoustics of a concert hall by effectively flattening a structural beam. Although the theory used to design such acoustic devices so far isn't as general as the one used to devise the microwave cloak, the finding nonetheless paves the way for other acoustic devices. 'We've now shown that both 2-D and 3-D acoustic cloaks theoretically do exist,' says Researcher Steven Cummer. 'It opens up the door to make the physical shape of an object different from its acoustic shape.'" -
Did Insects Kill the Dinosaurs?
Ponca City, We Love You writes "Asteroid impacts, massive volcanic flows, and now biting, disease-carrying insects have been put forward as an important contributor to the demise of the dinosaurs. In the Late Cretaceous the world was covered with warm-temperate to tropical areas that swarmed with blood-sucking insects. A theory explored by researchers at Oregon State suggests these bugs carried leishmania, malaria, intestinal parasites, arboviruses and other pathogens. Repeated epidemics may have slowly-but-surely worn down dinosaur populations while ticks, mites, lice and biting flies tormented and weakened them. 'After many millions of years of evolution, mammals, birds and reptiles have evolved some resistance to these diseases,' says Researcher George Poinar. 'But back in the Cretaceous, these diseases were new and invasive, and vertebrates had little or no natural or acquired immunity to them.' The confluence of new insect-spread diseases, loss of traditional food sources, and competition for plants by insect pests could all have provided a lingering, debilitating condition that dinosaurs were ultimately unable to overcome." -
The City of the Future
Ponca City, We Love You writes "One century ago, many Americans still had not seen a movie or ridden in an automobile. The New York World greeted its readers on January 1, 1908 with a stirring rumination about the past and future of America: 'We may have gyroscopic trains as broad as houses swinging at 200 miles an hour up steep grades and around dizzying curves,' the newspaper said. 'We may have aeroplanes winging the once inconquerable air. The tides that ebb and flow to waste may take the place of our spent coal and flash their strength by wire to every point of need.' Today the NY Times asked ten knowledgeable New Yorkers to imagine New York City a century from today. Their visions include archaeological excavations at the Fresh Kills landfill, the waterfront at Third Avenue and Seventh Avenue, a dome over Central Park, and a virtual reality grid superimposed over the city." -
The Death of High Fidelity
Ponca City, We Love You writes "Rolling Stone has an interesting story on how record producers alter the way they mix albums to compensate for the limitations of MP3 sound. Much of the information left out during MP3 compression is at the very high and low ends, which is why some MP3s sound flat. Without enough low end, 'you don't get the punch anymore. It decreases the punch of the kick drum and how the speaker gets pushed when the guitarist plays a power chord.' The inner ear automatically compresses blasts of high volume to protect itself, so we associate compression with loudness. After a few minutes, constant loudness grows fatiguing to the brain. Though few listeners realize this consciously, many feel an urge to skip to another song." -
Domains May Disappear After Search
Ponca City, We Love You writes "Daily Domainer has a story alleging that there may be a leak that allows domain tasters to intercept, analyze and register your domain ideas in minutes. 'Every time you do a whois search with any service, you run a risk of losing your domain,' says one industry insider. ICANN's Security and Stability Advisory Committee (SSAC ) has not been able to find hard evidence of Domain Name Front Running but they have issued an advisory (pdf) for people to come forward with hard evidence it is happening. Here is how domain name research theft crimes can occur and some tips to avoiding being a victim." -
People Were More Likely To Google Themselves This Year
Ponca City, We Love You writes "More than twice as many Americans googled themselves in 2006 than five years previous — and many are googling their friends and romantic interests as well, according to a report released ecently by the Pew Internet and American Life Project. The survey shows that the percentage of US adult Internet users who have looked for information about themselves through Google or another search engine has more than doubled in the past five years (pdf) from 22 percent in August, 2001 to 47 percent in December, 2006. Only 3 percent of internet self-googlers say they Google themselves regularly, 22 percent say 'every once in a while,' and three-quarters say they have googled themselves once or twice. The original report, 'Digital Footprints,' contains many more interesting observations (pdf)." -
Eat, Drink, and be Monitored
Ponca City, We Love You writes "A new restaurant has opened at Wageningen University in the Netherlands, fitted with a control center and two dozen hidden cameras devoted to exploring the question of what makes people eat and drink the way they do. Over the next 10 years, a team of more than 20 scientists will use the research facility to watch how people walk through the restaurant, what food catches their eye, whether they always sit at the same table and how much food they throw away. Researchers will examine environmental influences on eating behavior by making small changes in the color of the lights, in accompanying sounds, in the scents or the furniture. "We want to find out what influences people: colors, taste, personnel," said one researcher. "This restaurant is a playground of possibilities. We can ask the staff to be less friendly and visible or the reverse." University staff who want to eat at the new restaurant will have to sign a consent form agreeing to be watched." -
Auto Mileage Standards Raised to 35 mpg
Ponca City, We Love You writes "The Senate just passed a bill that will increase auto mileage standards for the first time in three decades. The auto industry's fleet of new cars, sport utility vehicles, pickup trucks and vans will have to average 35 mpg by 2020, a significant increase over the 2008 requirement of 27.5 mpg average. For consumers, the legislation will mean that over the next dozen years auto companies will likely build more diesel-powered SUVs and gas-electric hybrid cars as well as vehicles that can run on 85 percent ethanol. Automakers had vehemently opposed legislation in June that contained the same mileage requirements and Fortune magazine reported that American automakers were starting the miles-per-gallon race far behind Japan and that the new standards could doom US automakers. At the time, Chrysler officially put the cost of meeting the proposed rules at $6,700 per vehicle. The White House announced the President will sign the bill if it comes to his desk." -
Does Active SETI Put Earth in Danger?
Ponca City, We Love You writes "There is an interesting story in Seed Magazine on active SETI — sending out signals to try to contact other civilizations in nearby star systems. Alexander Zaitsev, Chief Scientist at the Russian Academy of Sciences' Institute of Radio Engineering and Electronics, has access to one of the most powerful radio transmitters on Earth and has already sent several messages to nearby, sun-like stars. But some scientists think that Zaitsev is not only acting out of turn by independently speaking for everyone on the entire planet but believe there are possible dangers we may unleash by announcing ourselves to the unknown darkness. This ground has been explored before in countless works of science fiction most notably "The Killing Star," a 1995 novel that paints a frightening picture of interstellar civilizations exterminating their neighbors with relativistic bombardments, not from malice, but simply because it is the most logical action." -
Can Time Slow Down?
Ponca City, We Love You writes "Does time slow down when you are in a traffic accident or other life threatening crisis like Neo dodging bullets in slow-motion in The Matrix? To find out, researchers developed a perceptual chronometer where numbers flickered on the screen of a watch-like unit. The scientists adjusted the speed at which the numbers flickered until it was too fast for the subjects to see. Then subjects were put in a Suspended Catch Air Device, a controlled free-fall system in which 'divers' are dropped backwards off a platform 150 feet up and land safely in a net. Subjects were asked to read the numbers on the perceptual chronometer as they fell [video]. The bottom line: While subjects could read numbers presented at normal speeds during the free-fall, they could not read them at faster-than-normal speeds. 'We discovered that people are not like Neo in The Matrix,' Eagleman said. 'The answer to the paradox is that time estimation and memory are intertwined: the volunteers merely thought the fall took a longer time in retrospect'." -
SenseCam Aids Patients with Memory Problems
Ponca City, We Love You writes "A small digital camera developed by Microsoft Research could boost memory in people with dementia and possibly mild forms of Alzheimer's disease. SenseCam is worn around the neck and automatically takes a wide-angle, low-resolution photograph every 30 seconds. It contains an accelerometer to stabilize the image and reduce blurriness, and it can be configured to take pictures in response to changes in movement, temperature, or lighting. An entire day's events can be captured and downloaded onto a PC where software converts the pictures into a short movie displaying the images at up to 10 frames per second, to allow patients to view a day's events in a few minutes to jolt their memory. "Not only does SenseCam allow people to recall memories while they are looking at the images, which in itself is wonderful, but after an initial period of consolidation, it appears to lead to long-term retention of memories over many months, without the need to view the images repeatedly," says neuropsychologist Emma Berry." -
Video Surveillance Identifies Threat Patterns
Ponca City, We Love You writes "When the 2008 Olympic Games kick off in Beijing next year, organizers will be using a sophisticated computer system to scan video images of city streets looking for everything from troublemakers to terrorists. The IBM system, called the Smart Surveillance System, uses analytic tools to index digital video recordings and then issue real-time alerts when certain patterns are detected. It can be used to warn security guards when someone has entered a secure area or keep track of cars coming in and out of a parking lot. The system can also search through old event data to find patterns that can be used to enable new security strategies and identify potential vulnerabilities. IBM is also developing a similar surveillance system for lower Manhattan, but has not yet begun deploying that project. "Physical security and IT security are starting to come together," says Julie Donahue, vice president of security and privacy services with IBM. "A lot of the guys I'm meeting on the IT side are just starting to get involved on the physical side."" -
Airlines to Offer In-Flight Internet Service
Ponca City, We Love You writes "JetBlue Airways will soon begin testing a free e-mail and instant messaging service on one aircraft, while American Airlines, Virgin America and Alaska Airlines plan to offer a broader Web experience in the coming months, probably priced at about $10 a flight. A recent survey found that 26 percent of leisure travelers would pay $10 for Internet access on a two-to-four-hour flight and 45 percent would pay that amount for a flight longer than four hours. The airlines plans to turn their planes into the equivalent of a wireless hot spot once the aircraft reaches its cruising altitude but service will not be available on takeoff and landing. While the technology could allow travelers to make phone calls over the Internet, most carriers say they have no plans to allow voice communications." -
Brain Changes When Viewing Violent Media
Ponca City, We Love You writes "Scientists at Columbia University have used Magnetic Resonance Imaging (fMRI) to show that a brain network responsible for suppressing inappropriate or unwarranted aggressive behaviors became less active after study subjects watched several short clips from popular movies depicting acts of violence. These changes could render people less able to control their own aggressive behavior. Although research has shown some correlation between exposure to media violence and real-life violent behavior, there has been little direct neuroscientific support for this theory until now. 'Depictions of violent acts have become very common in the popular media,' said researcher Christopher Kelly. 'Our findings demonstrate for the first time that watching media depictions of violence does influence processing in parts of the brain that control behaviors like aggression.' The full research paper is published on the The Public Library of Science, a peer-reviewed, open-access, online publication, that publishes all its articles under a Creative Commons Attribution License." -
Academic Games Are No Fun
Ponca City, We Love You writes "Academics have been flocking to use virtual worlds and multiplayer games as ways to research everything from economics to epidemiology and turn these environments into educational tools. A game called Arden, the World of Shakespeare, funded with a $250,000 MacArthur Foundation grant and developed at Indiana University was supposed to test economic theories by manipulating the rules of the game. There's only one problem. "It's no fun, " says Edward Castronova, Arden's creator and an associate professor of telecommunications at the university. "You need puzzles and monsters," he says, "or people won't want to play ... Since what I really need is a world with lots of players in it for me to run experiments on, I decided I needed a completely different approach." Part of the problem is it costs a lot to build a new multiplayer game. While his grant was large for the field of humanities, it was a drop in the bucket compared with the roughly $75 million that goes into developing something on the scale of World of Warcraft. Castronova is releasing Arden to the public as is and says his experience should serve as a warning for other academics. "What we've really learned is, you've got to start with a game first," Castronova says. "You just have to." The new version is titled Arden II: London Burning." -
NJ Blogger Fights for Anonymous Free Speech
Ponca City, We Love You writes "A New Jersey blogger is fighting for his right to blog anonymously and the Electronic Frontier Foundation (EFF) has asked a Superior Court judge in New Jersey to preserve the blogger's free speech rights as he faces legal threats from local government officials. On June 13, 2007, the New Jersey Township of Manalapan filed a malpractice suit against its former attorney Stuart Moskovitz, alleging misconduct regarding the Township's purchase of polluted land in 2005. The decision to file suit was met by a lively debate in the regional press and among local bloggers. One blogger who was particularly critical of the Township was datruthsquad. Attorneys for the Township issued a subpoena to Google demanding that the identity of this anonymous critic be turned over, along with datruthsquad's contact information, blog drafts, e-mails, and 'any and all information related to the blog.' Despite repeated requests from EFF to explain how this could be anything other than an attempt to out a vocal critic, attorneys for the Township have refused to withdraw the subpoena and informed EFF that it can go to court to object to the subpoena. In a motion to quash the subpoena, EFF has asked the court to block the township [PDF] in its attempt to uncover the identity of 'daTruthSquad' and allow the blogger to continue to write about this or any other issue without being forced to identity him or herself." -
Crime Wave Thwarted in Second Life
Ponca City, We Love You writes "The Mercury News reports that a vulnerability in the way Second Life protects a user's money has been identified. Risks for users are reportedly limited because the researchers say the flaw can be quickly patched. The flaw exploits a known problem with Apple's QuickTime - when a virtual character passes by an infected object planted by hackers, the Second Life software activates QuickTime so it can play the video or picture. Hackers can direct the Second Life software to a malicious Web site that then allows them to 'take over the user's avatar and force it to hand over its Linden cash. Second Life is recommending that users disable streaming video playback in the Second Life viewer except when you are attending a known and trusted venue.' The hack raises tough questions for operators of virtual worlds. Should they be as secure as banks and guarantee the safety of money and property that characters in the world possess?" -
AT&T Playing Hardball With Apple?
Ponca City, We Love You writes "There's some interesting speculation from Cringley on why AT&T chief executive Randall Stephenson let drop that a new version of Apple's iPhone will be introduced in 2008. The announcement is sure to cut into Apple's Christmas sales and could also cost ATT a million new customers and at least $1 billion in market cap, says Cringley. 'It is no coincidence that Stephenson made his remarks in Silicon Valley, rather than in San Antonio or New York,' says Cringley. 'He came to the turf of his 'partner' and delivered a message that will hurt Apple as much as AT&T, a message that says AT&T doesn't really need Apple despite the iPhone's success.' What may be troubling the relationship between AT&T and Apple is the upcoming auction for 700-MHz wireless spectrum and AT&T's discovery that Apple may be joining Google in bidding." -
Media Research Exec Says Music Industry Is On Its Last Legs
Ponca City, We Love You writes "For years, the major record labels have fought a pitched battle against the MP3 format. Although major labels like EMI and the Universal Music Group have embraced MP3s in recent months, a story from the Mercury News says early returns from those moves indicate they've had little impact on the industry's fortunes — for better or for worse. 'These are ailing businesses on their last legs,' said Eric Garland, chief executive of BigChampagne, a market research company focused on digital media. The question of copy protection on song downloads 'matters a whole lot less to them than it once did.' The industry has a bigger problem. Consumers used to buy CDs for $10 or $15 a pop. Increasingly, they're buying songs at about $1 apiece instead. So, even if transactions continue to increase, the industry is seeing far less money each time consumers buy and it's having a difficult time making up the difference." -
The Cultures of Texting In Europe and America
Ponca City, We Love You writes "The cultures of text messaging are very different in Europe and North America, according to an internet sociologist named Danah Boyd. Americans and Canadians have historically paid to receive text messages, but 'all-you-can-eat' data plans are beginning to change that. All-you-can-eat plans are still relatively rare in Europe. When a European youth runs out of texts and can't afford to top up, they simply don't text. But they can still receive texts without cost so they aren't actually kept out of the loop. What you see in Europe is a muffled fluidity of communication, comfortable but not excessive. " -
Mapping the Brain's Neural Network
Ponca City, We Love You writes "New technologies could soon allow scientists to generate a complete wiring diagram of a piece of brain. With an estimated 100 billion neurons and 100 trillion synapses in the human brain, creating an all-encompassing map of even a small chunk is a daunting task. Only one organism's complete wiring diagram now exists: that of the microscopic worm C. elegans, which contains a mere 302 neurons. The C. elegans mapping effort took more than a decade to complete. Research teams at MIT and at Heidelberg in Germany are experimenting with different approaches to speed up the process of mapping neural connections. The Germans start with a small block of brain tissue and bounce electrons off the top of the block to generate a cross-sectional picture of the nerve fibers. They then take a very thin slice, 30 nanometers, off the top of the block. 'Repeat this [process] thousands of times, and you can make your way through maybe the whole fly brain,' says the lead researcher. They are training an artificial neural network to emulate the human process of tracing neural connections to speed the process about 100- to 1000-fold. They estimate that they need a further factor of a million to analyze useful chunks of the human brain in reasonable times." -
Turning E-Mail into a Social Network
Ponca City, We Love You writes "Saul Hansell at the NY Times has an interesting article on his technology blog about his conversations with executives at Yahoo and Google about how they plan to turn their e-mail systems and personalized home page services into social networks. Web-based e-mail systems already contain much of what Facebook calls the social graph — the connections between people. That's why social networks offer to import the e-mail address books of new users to jump-start their list of friends. Yahoo and Google realize they can use this information to build their own services that connect people to their contacts. Yahoo is working on what they call "Inbox 2.0" which will display messages more prominently from people who are more important to you, determining the strength of your relationship by how often you exchange e-mail and instant messages with him or her. "The inbox you have today is based on what people send you, not what you want to see," says Brad Garlinghouse, who runs communication and community products for Yahoo. "We can say, here are the messages from the people you care about most." There will also be some sort of profile system attached to Inbox 2.0 with a profile users show to others and a personal page where they can see information from their friends. "The exciting part is that a lot of this information already exists on our network, but it's dormant," Mr. Garlinghouse added." -
Close but no Cigar for Netflix Recommender System
Ponca City, We Love You writes "In October 2006, Netflix, the online movie rental service, announced that it would award $1 million to the first team to improve the accuracy of Netflix's movie recommendations by 10% based on personal preferences. Each contestant was given a set of data from which three million predictions were made about how certain users rated certain movies and Netflix compared that list with the actual ratings and generated a score for each team. More than 27,000 contestants from 161 countries submitted their entries and some got close, but not close enough. Today Netflix announced that it is awarding an annual progress prize of $50,000 to a group of researchers at AT&T Labs, who improved the current recommendation system by 8.43 percent but the $1 million grand prize is still up for grabs and a $50,000 progress prize will be awarded every year until the 10 percent goal is met. As part of the rules of the competition, the team was required to disclose their solution publicly. (pdf)"
