Apple Says 250,000 iPhones Sold to Unlockers
Hugh Pickens writes "Timothy D. Cook, Chief Operating Officer at Apple, disclosed during Apple's conference call to discuss their fourth quarter earnings that they estimate 250,000 of the 1.4 Million iPhones that have been sold were bought by people intending to unlock the phone. 'The elasticity in demand with the price drop] enabled us to far surpass our expectation of hitting around a million units cumulatively by the end of the quarter. Some number of these were sold to people that have an intention to unlock and [while] we don't know precisely how many people are doing that, our current guess is there is probably 250,000 of the 1.4 million that we sold where people had bought them with the intention of doing that. Many of those happened after the price cut.' Apple knows how many iPhones have been sold and how many have been activated with ATT. The difference is the number that are unlocked." -
Space Elevator Teams Compete for NASA Prizes
Hugh Pickens writes "The University of Saskatchewan's has the first place climb in the Second Annual Space Elevator Games being held this weekend at the Davis County Event Center in Salt Lake City. Teams are competing for $1,000,000 in NASA prize money. Although the idea of a space elevator has been around for decades, the space technologies needed to support it have yet to be created. The non-profit Spaceward Foundation has hosted an annual competition since 2005 to build a super-strong tether, or get a robot to climb a suspended ribbon. In the robot climber competition, teams have to get their device to hurtle up a 100-metre-long ribbon, suspended from a crane, at an average speed of two metres per second. The climber must be powered from the ground: strategies include reflecting sunlight from huge mirrors on the ground to solar panels on the climber; shining lasers from the ground up to similar panels on the robot; or firing microwaves up at the climber. Qualifying rounds have been taking place all week, and although high winds and rain have caused delays, four out of eight teams have made it into the finals. There are no outdoor climbs today because of bad weather but some of the tether competitions will happen indoors later this afternoon." -
Crashed Spacecraft Yields Data on Solar Wind
Hugh Pickens writes "After the Genesis mission spent 27 months in space gathering tiny samples from different types of solar wind, Hollywood stunt pilots swooped in with a helicopter to catch the falling capsule when it returned to earth. Unfortunately the spacecraft's parachute did not open, and the spacecraft ploughed a hole into the desert. Now scientists are starting to recover data from the salvageable pieces of Genesis. Nature Magazine reports that an analysis of isotopes of neon and argon shows that the elements of main interest to the researchers have the same isotopic signature in the solar wind as in the Sun itself. Because dirt contains relatively little neon and argon, the current Science study wasn't affected too much by contamination and the the team remains hopeful that they will be able to get results on oxygen and nitrogen isotopes from the mission." -
New GPS Navigator Relies On 'Wisdom of the Crowds'
Hugh Pickens writes "The New York Times is running an article on Dash Express, a new navigation system for automobiles that not only receives GPS location data, but broadcasts information about its travels. Information is passed back to Dash over a cellular data network, where it is shared with other users to let them know if there are slowdowns or traffic jams on the road ahead. The real benefit of the system isn't apparent until enough units are collecting data in a given area - so Dash distributed over 2,000 prototype units to test drivers in 25 large cities." -
Neuro-Reckoning May Reduce MMOG Time Lag
Hugh Pickens writes "Time lag can cause some very strange behavior in massively multiplayer online games when players' actions onscreen become slow and jerky. New techniques are on the way to reduce the problem of lag time in MMOGs when a player's computer can't keep up with changes in a shared online world. Games like Quake use a technique called dead reckoning and while traditional dead-reckoning systems that assume that a game character will maintain the velocity and direction that it has at the moment an update is sent to all other participating computers; dead reckoning works best for movement and shooting and less well for erratic actions such as interacting with objects or with other players. Read the abstract of new technique called 'neuro-reckoning' that may improve the predictive process by installing a neural network in each player's computer to predict fast, jerky actions." -
Evidence Found for Earliest Modern Humans
Hugh Pickens writes "Researchers at Arizona State University report that they have pushed back the date for the earliest modern humans to 164,000 years ago, far earlier than previously documented. Paleoanthropologists now say that genetic and fossil evidence suggests that modern human species — Homo sapiens — evolved in Africa between 100,000 and 200,000 years ago and in seeking the "perfect site" to explore for remains of the earliest populations, researchers analyzed ocean currents, climate data, geological formations and other data to pin down a location. "The world was in a glacial stage 125,000 to 195,000 years ago, and much of Africa was dry to mostly desert; in many areas food would have been difficult to acquire. The paleoenvironmental data indicate there are only five or six places in all of Africa where humans could have survived these harsh conditions," said Curtis Marean, a professor in ASU's School of Human Evolution and Social Change. Photos from the cave at Pinnacle Point in South Africa show where the team found ochre, bladelets and evidence of shellfish — findings that reveal the earliest dated evidence of modern humans." -
Infrequent Anonymous Cowards Reliable on Wikipedia
Hugh Pickens writes "Researchers at Dartmouth University have recently discovered that infrequent anonymous contributors, so called "Good Samaritans," are as reliable as registered users who update constantly and have a reputation to maintain. A graph from page 31 of the group's original paper (pdf file) shows that the quality of contributions of anonymous users goes down as the number of edits increases while quality goes up with the number of edits for registered users." -
Attacking Criminal Networks On the Internet
Hugh Pickens writes "Computer Scientists at Carnegie Mellon University are developing techniques to analyze and disrupt black markets on the internet, where criminals sell viruses, stolen data, and attack services estimated to total more than $37 million for the seven-month period they studied. To stem the flow of stolen credit cards and identity data, researchers have proposed two technical approaches to reducing the number of successful market transactions. One approach to disrupting the network is a slander attack where an attacker eliminates the verified status of a buyer or seller through false defamation. Another approach undercuts the cyber-crooks' network by creating a deceptive sales environment. 'Just like you need to verify that individuals are honest on E-bay, online criminals need to verify that they are dealing with "honest" criminals,' says Jason Franklin, one of the researchers." -
The Dark Side of Iapetus
Hugh Pickens writes "The difference in coloring between Iapetus' leading and trailing hemispheres is striking. NASA's Jet Propulsion Labs has just released a report on a bizarre 'runaway' process that may explain the strange and dramatically two-toned appearance recently revealed in images collected during a close flyby by the Cassini spacecraft. Scientists believe that initially dark material on one side of Iapetus may have come from other moons orbiting Saturn in the opposite direction. Since Iapetus is locked in synchronous rotation about Saturn, as dusty material from the outer moons spiraled in and hit Iapetus head-on, the forward-facing side began to darken. As it absorbed more sunlight, its surface water evaporated, and vapor was transported from the dark side to the white side of Iapetus. Thermal segregation then proceeded in a runaway process as the dark side lost its surface ice and got darker still. Now the leading hemisphere is as dark as a tarred street and the trailing hemisphere resembles freshly fallen snow." -
Google Hopes to Disaggregate Carriers with gPhone
Hugh Pickens writes "The New York Times has a look at Google's plan to loosen the carriers' control over their mobile phone networks in an effort to bring the dynamics of the PC-oriented Internet to the mobile Internet hoping that it can beat competitors in an open environment. The Google Phone or gPhone which is expected to be unveiled later this year will not compete with the iPhone but will help Google distribute their online services. Google intends to provide software that will be built into phones sold by many manufacturers and, unlike Microsoft's Windows Mobile, Google is not expected to charge phone makers a licensing fee for their software. Google will make its money brokering ads on the mobile phones and even envisions a free phone service one day supported entirely through ad revenue." -
Titan's Tropical Weather
Hugh Pickens writes "Climate researchers Ray Pierrehumbert and Jonathan Mitchell at the University of Chicago say that Titan, the only moon in the solar system large enough to support an atmosphere, has many of the same weather features as Earth, but with completely different substances that work at temperatures that plunge down to minus 170 degrees Celsius. Pierrehumbert and Mitchell call Titan's climate 'tropical,' a climate that is warm to hot and wet year-round, because on Titan methane assumes the role of water and exists in enough abundance to condense into rain and form puddles on the surface. Titan's tropical nature means that scientists can observe the behavior of its clouds using theories they've developed to understand Earth's tropics. For example, Titan's atmosphere produces an updraft where surface winds converge to lift evaporated methane up to cooler temperatures and lower pressures, where much of it condenses and forms clouds, 'a well-known feature on Earth called an ITCZ, the inter-tropical convergence zone,' Mitchell says." -
Mutant Algae to Fuel Cars of Tomorrow?
Hugh Pickens writes "Algae has long been known as a promising source of biodiesel. It's worth noting, though, that algae also produces a small amount of hydrogen during photosynthesis. The MIT Technology Review reports that researchers have created a mutant algae that makes better use of sunlight to increase the amount of hydrogen that the algae produce. Anastasios Melis and his team at the University of California have manipulated the genes that control the amount of chlorophyll in the algae's chloroplasts. Although the process is still at least five years from being used for hydrogen generation, Melis estimates that if 50% of the algae's photosynthesis could be directed toward hydrogen production, an acre could produce 40 kilograms of hydrogen per day. At the price of $2.80 a kilogram, hydrogen could compete with gasoline, since a kilogram of hydrogen is equivalent in energy to a gallon of gasoline." -
First New Nuclear Plant in US in 30 years
Hugh Pickens writes "With backing from the White House and congressional leaders, and subsidies like the $500 million in risk insurance from the Department of Energy, the nuclear industry is experiencing a revival in the US. Scientific American reports that this week NRG Energy filed an application for the first new nuclear power plant in the US in thirty years to build two advanced boiling water reactors (ABWR) at its South Texas nuclear power plant site doubling the 2700 megawatts presently generated at the facility. The ABWR, based on technology already operating in Japan, works by using the heat generated by the controlled splitting of uranium atoms in fuel rods to directly boil water into steam to drive turbines producing electricity. Improvements over previous designs include removing water circulation pipes that could rupture and accidentally drain water from the reactor, exposing the fuel rods to a potential meltdown, and fewer pumps to move the water through the system. NRG projects it will spend $6 billion constructing the two new reactors and hopes to have the first unit online by 2014." -
Future Looks Bright for Large Scale Solar Farms
Hugh Pickens writes "The economist reports that Concentrating Solar Power (CSP) systems that capture and focus the sun's rays to heat a working fluid and drive a turbine, are making a comeback. Although the world's largest solar farm was built over twenty years ago, until recently no new plants have been built. Now with the combination of federal energy credits, the enactment of renewable energy standards in many states, and public antipathy to coal fired power plant, the first such plant to be built in decades started providing 64 megawatts of electricity to Las Vegas this summer. Electricity from the Nevada plant costs an estimated 17 cents per kilowatt hour (kWh), but projections suggest that CSP power could fall to below ten cents per kWh as the technology improves. Coal power costs just 2-3 cents per kWh but that will likely rise if regulation eventually factors in the environmental costs of the carbon coal produces." -
Cleaning up the Most Toxic Pollution in the World
Hugh Pickens writes "Blacksmith Institute has published their list of the most polluted sites in the world compiled by comparing the toxicity of the contamination, the likelihood of it getting into humans and the number of people affected. For example, ninety-nine percent of the children living in and around the poly-metallic smelter at La Oroya in Peru, owned by the Missouri-based Doe Run Corporation, have blood lead levels that exceed acceptable limits. Scientific American says that despite the massive pollution, it would be relatively cheap and easy to clean up the most dangerous hazards. For $15,000, the radioactive contaminated soil from the Mayak plutonium facility on the shore of the Techa River in the Russian town of Muslyomova could be dug up, saving an estimated 350 lives. 'For about $200, the cost of a refrigerator, we are able to save someone's life,' says Richard Fuller, founder of Blacksmith." -
New Technologies Attack the One-World Problem
Hugh Pickens writes "An MIT Technology Review article has new details on the challenges of a 'one world design' in Massively Multiplayer Online Games. Most games shard their servers, putting up artificial barriers between friends and family members. Technologies are now being developed to keep lots of players within a single world, some of them based off of the unique PvP-heavy title EVE Online. The best part - the technologies don't just apply to gaming. 'NASDAQ, for example, can be thought of as a very large MMO, supporting very large numbers of 'players' performing billions of transactions daily in a graphically intense environment, all within a single shard. Technologies that solve this problem effectively, says George Dolbier, technical lead for games and interactive entertainment at IBM, will have applications in any industry that requires spotting and reacting to trends, or "anything where behavior is dynamic and you need to move resources around rapidly."'" -
New Wonder Weed to Fuel Cars?
Hugh Pickens writes "Jatropha, an ugly, fast-growing and poisonous weed that has been used as a remedy for constipation, may someday power your car. The plant, resilient to pests and resistant to drought, produces seeds with up to 40 per cent oil content that when crushed can be burned in a diesel car while the residue can be processed into biomass for power plants. Although jatropha has been used for decades by farmers in Africa as a living fence because its smell and taste repel grazing animals, the New York Times reports that jatropha may replace biofuels like ethanol that require large amounts of water, fertilizer, and energy, making their environmental benefits limited. Jatropha requires no pesticides, little water other than rain and no fertilizer beyond the nutrient-rich seed cake left after oil is pressed from its nuts. Poor farmers living close to the equator are planting jatropha on millions of acres spurred on by big oil companies like British Petroleum that are investing in jatropha cultivation." -
Making War On Light Pollution
Hugh Pickens writes "Almost thirty years ago I worked in the Middle East helping install a nationwide communications system and had the opportunity to be part of a team doing microwave link tests across Saudi Arabia's Empty Quarter. Something I've never forgotten were the astonishing nights I spent in the desert hundreds of miles from the nearest city where the absence of light made looking at the sky on a moonless night feel like you were floating in the middle of the galaxy. In Galileo's time, nighttime skies all over the world would have merited the darkest Bortle ranking, Class 1. Today, the sky above New York City is Class 9 and American suburban skies are typically Class 5, 6, or 7. The very darkest places in the continental United States today are almost never darker than Class 2, and are increasingly threatened. Read a story from the New Yorker on what we have lost to light pollution and how some cities are adopting outdoor lighting standards to save the darkness." -
New Explanation For the Industrial Revolution
Pcol writes "The New York Times is running a story on Dr. Gregory Clark's book 'A Farewell to Alms,' which offers a new explanation for the Industrial Revolution and the affluence it created. Dr. Clark, an economic historian at the University of California Davis, postulates that the surge in economic growth that occurred first in England around 1800 came about because of the strange new behaviors of nonviolence, literacy, long working hours, and a willingness to save. Clark's research shows that between 1200 and 1800, the rich had more surviving children than the poor and that he postulates that this caused constant downward social mobility as the poor failed to reproduce themselves and the progeny of the rich took over their occupations. 'The modern population of the English is largely descended from the economic upper classes of the Middle Ages,' Clark concludes. Work hours increased, literacy and numeracy rose, and the level of interpersonal violence dropped. Around 1790, a steady upward trend in production efficiency caused a significant acceleration in the rate of productivity growth that at last made possible England's escape from the Malthusian trap." -
Houston, We Have a Drinking Problem
Pcol writes "Aviation Week reports that astronauts were allowed to fly on at least two occasions after flight surgeons and other astronauts warned they were so intoxicated that they posed a flight-safety risk. A review panel, convened in the wake of the Lisa Nowak arrest to review astronaut medical and psychological screening, also reported "heavy use of alcohol" by astronauts before launch, within the standard 12-hour "bottle to throttle" rule applied to NASA flight crew members. Dr. Jonathan Clark, a former NASA flight surgeon, says it's a tradition for crew members to gather for a barbecue on the eve of a shuttle launch, and these gatherings sometimes include alcohol and a toast but that the greater problem is that preparation before a flight can leave astronauts sleep-deprived and overworked. Meanwhile at Frenchie's Italian Restaurant, a popular astronaut hangout in Houston, owner Frankie Camera disputed the reports: "The Mercury astronauts may have been a little more wild (than later ones) but I did banquets for them and never really saw any of them drink so much they were out of control or drunk."" -
Humans Can Still Out-Bluff Machines
Pcol writes "The New York Times reports that in a poker game this week between man and machine, a program called Polaris fought a close match, but lost to two well-known professional poker players. Designing a poker playing algorithm is a different and more difficult challenge for software designers than chess and checkers because of uncertainties introduced by the hidden cards held by each player and difficult-to-quantify risk-taking behaviors such as bluffing. The game-tree approach doesn't work in poker because in many situations there is no one best move and a top-notch player adapts his play over time, exploiting his opponent's behavior. Polaris build a series of "bots" that have differing personalities or styles of play, ranging from aggressive to passive. Researchers monitored the performance of three bots and then moved them in and out of the lineup like football players." -
High-Tech Squirrels Trained to Conduct Espionage
Pcol writes "In the July 20 issue of the Washington Post, columnist Al Kamen reports that the BBC has translated a story headlined 'spying squirrels,' published in the Iranian newspaper Resalat on the use of trained animals to conduct espionage against their country: 'A few weeks ago, 14 squirrels equipped with espionage systems of foreign intelligence services were captured by [Iranian] intelligence forces along the country's borders. These trained squirrels, each of which weighed just over 700 grams, were released on the borders of the country for intelligence and espionage purposes.' According the story the squirrels had 'GPS devices, bugging instruments and advanced cameras' in their bodies. 'Given the fast speed and the special physical features of these animals, they provide special capabilities for spying operations. Once the animals return to their place of origin, the intelligence gathered by them is then offloaded. . . .' Iranian police officials captured the squirrels before they could carry out their assignments."
