US Embassy Categorizes Beijing Air Quality As 'Crazy Bad'
digitaldc writes "Pollution in Beijing was so bad Friday the US embassy, which has been independently monitoring air quality, ran out of conventional adjectives to describe it, at one point saying it was 'crazy bad.' The embassy later deleted the phrase, saying it was an 'incorrect' description and it would revise the language to use when the air quality index goes above 500, its highest point and a level considered hazardous for all people by US standards. The hazardous haze has forced schools to stop outdoor exercises, and health experts asked residents, especially those with respiratory problems, the elderly and children, to stay indoors." -
Factory To Make Biodiesel From Chicken Fat
telekon writes "Tyson foods has finally found a use for chicken fat and leftover food grease that isn't McNuggets — they've partnered with Syntroleum to produce biodiesel from the stuff. Their first plant in Louisiana will be able to churn out 75 million gallons a year. The question is, will the exhaust smell like fried chicken?" -
Why You See 'Free Public WiFi' In So Many Places
An anonymous reader writes "Almost anywhere you go these days (particularly at airports), if you check for available WiFi settings, you have a pretty good chance of seeing an ad hoc network for 'Free Public WiFi.' Of course, since it's ad hoc (computer to computer) it's not actually access to the internet. So why is this in so many places? Turns out it's due to a bug in Windows XP. Apparently, the way XP works is that if it can't find a 'favorite' WiFi hotspot, it automatically sets up the computer to broadcast itself as an ad hoc network point, using the name of the last connection the computer attempted. So... people see 'Free Public WiFi' and they try to log on. Then their own computer starts broadcasting the same thing, because it can't find a network it knows. And, like a virus, the 'Free Public WiFi' that doesn't work lives on and on and on." -
Some Countries Want To Ban 'Information Weapons'
DrgnDancer sends in an NPR piece on recent efforts to control so-called "information weapons" on the Internet. What's interesting is that the term "information weapon," as defined by many of the countries trying to limit them, doesn't mean what you would think. It's closer to the old Soviet term "ideological aggression." "At a UN disarmament conference in 2008, Sergei Korotkov of the Russian Defense Ministry argued that anytime a government promotes ideas on the Internet with the goal of subverting another country's government — even in the name of democratic reform — it should qualify as 'aggression.' And that, in turn, would make it illegal under the UN Charter. 'Practically any information operation conducted by a state or a number of states against another state would be qualified as an interference into internal affairs,' Korotkov said through an interpreter. 'So any good cause, like [the] promotion of democracy, cannot be used as a justification for such actions.' The Russians, and a lot of other countries such as Iran and China, apparently consider the free exchange of information to be an information technology threat. One that must be managed by treaty." -
How Your Brain Figures Out What It Doesn't Know
hex0D passes along an article at NPR about a study that examined the biology behind the self-assessment of knowledge. Quoting: "We isolated a region of the prefrontal cortex, which is right at the front of the brain and is thought to be involved in high-level thought, conscious planning, monitoring of our ongoing brain activity,' Fleming says. In people who were good at assessing their own level of certainty, that region had more gray matter and more connections to other parts of the brain, according to the study Fleming and his colleagues published in the journal Science." -
The Advent of Religious Search Engines
Beetle B. writes "Do Google search results contradict your religious views? Tired of getting pornographic results and worried you'll burn in Hell for it? Are you Christian? Try SeekFind — 'a Colorado Springs-based Christian search engine that only returns results from websites that are consistent with the Bible.' Muslim? Look no further: I'm Halal. Jewish? Jewogle is for you. NPR ran a story on the general trend of search engines cropping up to cater to certain religious communities. I wonder how many other 'filtered' search engines exist out there to cater to various groups (religious or otherwise) — not counting specialized searches (torrents, etc)." -
BP's Gulf Spill Report Shows String of Failures
eldavojohn writes "News is out of BP's report on the gulf spill that shifts some of the blame on to other companies like Transocean that worked with BP in erecting the Deepwater Horizon rig. If you were affected by the spill, you might find the video, executive summary and 193-page report an interesting read. The summary outlines six or seven major failures in safety and engineering that all built up to the deaths of eleven workers and widespread contamination of the gulf. From incorrectly using seawater instead of drilling fluid to misinterpreting pressure test results, this report is just BP's side of the story as the blowout preventer has been pulled up and is still on its way to NASA where it will be analyzed by government investigators who will be able to compile their own report." -
"Granny Pods" Keep Elderly Close, At Safe Distance
Are you concerned enough about an elderly loved one to let them live in your backyard but not your house? Then a "Granny Pod" might be right for you. From the article: "The granny pod's real name is the MEDCottage, and it's basically a mini mobile home that rents for about $2,000 a month. You park one in the backyard, hook it up to your water and electricity, and it becomes a free-standing spare room for Grandma and Grandpa." -
"Choose Your Own Adventure" On Your iPhone
If you spent a good portion of your childhood reading the classic "Choose Your Own Adventure" books, you'll be glad to know that you can soon waste countless hours at work turning to random pages on your iPhone. Edward Packard, one of the original authors of the series, has helped create an app called U-Ventures which uses special effects to create a story in the traditional Choose Your Own Adventure format. From the article: "The first U-Venture is a sort of a sequel to a classic title, The Cave of Time. In 'Return to the Cave of Time,' the U-Venture, 'you go back in the cave — you don't have a choice on that,' Packard tells NPR's Neal Conan. But from that point on, the reader chooses her own course." -
Having Too Much Information Can Narrow Your Focus
CeruleanDragon writes "This excerpt sums up Dave Pell's article at NPR pretty well: 'Google's Eric Schmidt recently stated that every two days we create as much information as we did from the beginning of civilization through 2003. Perhaps the sheer bulk of data makes it easier to suppress that information which we find overly unpleasant. Who has got time for a victim in Afghanistan or end-of-life issues with all these tweets coming in?' It's a valid point. If it's not tweets or Facebook posts, it's lengthy forum arguments or reading news articles from the time you walk in the door at work until you're ready for bed at night, and realizing you didn't actually accomplish anything else. Sometimes too much information can get in the way of living and can bury otherwise important things." -
The Great Typo Hunt
jamie writes "Incensed by a 'no tresspassing' sign, Jeff Deck launched a cross-country trip to right grammatical wrongs. He enlisted a friend, Benjamin D. Herson, and together they erased errant quotation marks, rectified misspellings and cut unnecessary possessive apostrophes. The Great Typo Hunt is the story of their crusade." We have already covered the duo's fight with The National Park Service. -
Genetically Modified Canola Spreads To Wild Plants
eldavojohn writes "A research team conducting a survey has found that about 86% of wild canola plants in North Dakota have genetically modified genes in them, and 'two samples contained multiple genes from different species of genetically modified plants.' Canola usually has little competition when cultivated but does not fare well in the wild. The Roundup Ready and Liberty Link strains of genetically modified canola appear to be crossing over to wild plants and helping it survive. The University of Arkansas team claims that the ease in which genetically modified canola has 'escaped' into the wild should be noted by seed makers like Monsanto because this is proof that it will happen." Reader n4djs notes that Monsanto has been known to sue farmers for patent infringement when their crops unintentionally contain genetically modified plants. -
The Museum Of Bad Art
There are plenty of places you can go to look at fine works of art, but where can you find the stuff that doesn't even belong on a refrigerator door? The Museum of Bad Art just outside of Boston is dedicated to art gone wrong in one way or another. Head of the museum Michael Frank says, "What we look for are pieces of work that are produced in an attempt to make some sort of artistic statement — but clearly something has gone wrong. There has to be something about it that makes you stop, and very often wonder why the artist continued down the path to produce what he or she did." -
Driverless Cars Begin 8,000-Mile Trek
apoc.famine writes "Driverless technology from the University of Parma's VisLab was deployed in a real-world test on Tuesday. Two driverless chase vehicles will attempt to follow two lead vehicles across multiple continents, from Italy to China, over the course of three months. The journey will cover over 8,000 miles, (~13,000 km) as the chase vehicles use lasers and cameras to navigate hazards along the way. The team expects to collect about 100 TB of data, which requires a hefty electronics and battery load — the scale is such that the cars can only run for about three hours before needing 8 hours to recharge the batteries. This journey is being billed as just a test, and far from a real-world application. The vehicles don't go more than about 35mph, and need a person behind the wheel to take over at a moment's notice. 'What we are trying to do is stress our systems and see if they can work in a real environment, with real weather, real traffic, and crazy people who cross the road in front of you and a vehicle that cuts you off,' said project leader Alberto Broggi. The goal is not to produce just road vehicles, but to improve the technology so it can be used in military and agricultural roles as well. The team hopes to have helped mature the technology within the next 10-20 years to the point that it can be used on the road." -
Cyberwarrior Shortage Threatens US Security
An anonymous reader writes "US security officials say the country's cyberdefenses are not up to the challenge. In part, it's due to a severe shortage of computer security specialists and engineers with the skills and knowledge necessary to do battle against would-be adversaries. The protection of US computer systems essentially requires an army of cyberwarriors, but the recruitment of that force is suffering. 'We don't have sufficiently bright people moving into this field to support those national security objectives as we move forward in time,' says James Gosler, a veteran cybersecurity specialist who has worked at the CIA, the National Security Agency, and the Energy Department." -
Given Truth, the Misinformed Believe Lies More
SharpFang writes "In a series of studies in 2005 and 2006, researchers at the University of Michigan found that misinformed people, particularly political partisans, rarely changed their minds when exposed to corrected facts in news stories. In fact, they often became even more strongly set in their beliefs. Facts, they found, were not curing misinformation. Like an underpowered antibiotic, facts could actually make misinformation even stronger." -
A Look Back At Bombing the Van Allen Belts
An anonymous reader points out a recent story at NPR describing one of the greatest lightshows in history — a US hydrogen bomb test 250 miles above the Pacific Ocean in 1962. The mission came about after James Van Allen confirmed the existence of radiation belts around the earth that now bear his name. As it turns out, the same day Van Allen announced his findings at a press conference, he "agreed with the military to get involved with a project to set off atomic bombs in the magnetosphere to see if they could disrupt it." According to NPR, "The plan was to send rockets hundreds of miles up, higher than the Earth's atmosphere, and then detonate nuclear weapons to see: a) If a bomb's radiation would make it harder to see what was up there (like incoming Russian missiles!); b) If an explosion would do any damage to objects nearby; c) If the Van Allen belts would move a blast down the bands to an earthly target (Moscow! for example); and — most peculiar — d) if a man-made explosion might 'alter' the natural shape of the belts." The article is accompanied by a podcast and a video with recently declassified views of the test. They also explain how the different colors of light in the sky were produced. -
SCOTUS Rules Petiton Signatures Are Public Record
Reader SheeEttin reminds us that back in October, the Supreme Court accepted a case testing whether or not petition signers' names could be kept anonymous. (The premise was that the act of signing a petition is covered by free speech, and thus signers are entitled to anonymity, especially to protect them from harassment.) Now the Court has issued its ruling: signatures are part of the public record. "By a strong majority Thursday, the Supreme Court issued a setback for opponents of gay marriage who wanted to keep their identities secret. The justices favored transparency over privacy in a case testing whether signing a petition is a public act. The case began with a bill that the Washington state legislature passed in 2009, expanding the state's domestic partnership law. The new referendum was known as 'everything but marriage' for the enhanced rights it gave same-sex couples. People who opposed the bill gathered 120,000 signatures for a ballot measure asking voters to repeal it. That measure eventually reached Washington voters, who upheld 'everything but marriage.' Those who signed the repeal petition feared that they would be harassed if their names became public, so they went to court challenging Washington's Public Records Act. They argued that signing a petition is speech that is protected from disclosure. But in Thursday's 8-1 ruling, the Supreme Court disagreed. 'Such disclosure does not, as a general matter, violate the first amendment,' Chief Justice John Roberts wrote for the court." -
McDonald's, Cadmium, and Thermo Electron Niton Guns
An anonymous reader writes, snipping from a story at NPR: "'How did the Consumer Products Safety Commission find out that cadmium, a toxic metal, was present on millions of Shrek drinking glasses now being recalled by McDonald's? Well, an anonymous person with access to some pretty slick testing equipment tipped off Rep. Jackie Speier (D-CA) about the problem. Her office confirmed that somebody using a Thermo Electron Niton XRF testing gun found a lot of cadmium, sometimes used in yellow pigments, on the surface of the glasses. The source overnighted glasses to Speier's office last week, which then turned over the test results and specimens to the CPSC. ... By law, no more than 75 parts per million of cadmium is supposed to be present in paint on kids toys. Speier's office said the amount found on the glasses was quite a bit higher than that.' Seems like the answer to a previous question about at-home science — this blogger seems to have been one of the anonymous sources." -
New Ebola Drug 100% Effective In Monkeys
TrisexualPuppy writes "A team of scientists at Boston University has created a cure for the Ebola virus, first discovered in 1976. After setting the correct dosages, all monkeys tested with the vaccine survived with only mild effects. No tests have been performed on humans yet, as outbreaks happen infrequently and are difficult to track. Quoting NPR: '[The drug] contains snippets of RNA derived from three of the virus's seven genes. That "payload" is packaged in protective packets of nucleic acid and fat molecules. These little stealth missiles attach to the Ebola virus's replication machinery, "silencing" the genes from which they were derived. That prevents the virus from making more viruses.'" -
Citizen Scientists Help Explore the Moon
Pickens writes "NPR reports that NASA's Lunar Reconnaissance Orbiter is doing such a good job photographing every bit of the moon's surface that scientists can't keep up, so Oxford astrophysicist Chris Lintott is asking amateur astronomers to help review, measure, and classify tens of thousands of moon photos streaming to Earth using the website Moon Zoo, where anyone can log on, get trained, and become a space explorer. 'We ask people to count the craters that they can see ... and that tells us all sorts of things about the history and the age of that bit of surface,' says Lintott. Volunteers are also asked to identify boulders, measure the craters, and generally classify what is found in the images. If one person does the classification — even if they're an expert — then anything odd or interesting can be blamed on them. But with multiple independent classifications, the team can statistically calculate the confidence in the classification. That's a large part of the power of Moon Zoo. Lintott adds the British and American scientists heading up the LRO project have been randomly checking the amateur research being sent in and find it as good as you would get from an expert. 'There are a whole host of scientists ... who are waiting for these results, who've already committed to using them in their own research.'" -
Oil Arrives In Louisiana; Defense Booms Inadequate
eldavojohn writes "People in mainland Louisiana are seeing the beginnings of the oil's full effects on wildlife in the area. Sticky, rust-colored oil covers the reeds like a latex paint, indicating that the efforts to lay miles of floating booms to keep it away from the fragile marshes are useless. They are experiencing what the Plaquemines (mouth of Mississippi River) saw last week, and it now appears that their defenses were inadequate. Only time will tell how much worse it can get as BP still scrambles for a solution. NPR also ran a story critical of Obama's 'scientific approach' that he promised to use in office and how well it's being applied and holding up during this crisis." -

Scientists Question Safety of New Airport Scanners
An anonymous reader sends this quote from a story at NPR about the accelerated deployment of new scanning machines at airports: "Fifty-two of these state-of-the-art machines are already scanning passengers at 23 US airports. By the end of 2011, there will be 1,000 machines and two out of every three passengers will be asked to step into one of the new machines for a six-second head-to-toe scan before boarding. About half of these machines will be so-called X-ray back-scatter scanners. They use low-energy X-rays to peer beneath passengers' clothing. That has some scientists worried. ... The San Francisco group thinks both the machine's manufacturer, Rapiscan, and government officials have miscalculated the dose that the X-ray scanners deliver to the skin — where nearly all the radiation is concentrated. The stated dose — about .02 microsieverts, a medical unit of radiation — is averaged over the whole body, members of the UCSF group said in interviews. But they maintain that if the dose is calculated as what gets deposited in the skin, the number would be higher, though how much higher is unclear." -
Parody and Satire Videos, Which Is Fair Use?
Hugh Pickens writes "Ben Sheffner writes that both sides in Don Henley's lawsuit against California US Senate candidate Chuck DeVore (R) over campaign 'parody' videos that used Henley's tunes set to lyrics mocking Sen. Barbara Boxer (D) have now filed cross-motions for summary judgment, teeing up a case that will likely clarify the rules for political uses of third-party material. The motions focus largely on one issue: whether the videos, which use the compositions 'The Boys of Summer' and 'All She Wants to do is Dance,' are 'parodies,' and thus likely fair uses, or, rather, unprivileged 'satires.' The Supreme Court in Campbell v. Acuff-Rose Music, 510 U.S. 569 (1994), said that a parody comments on the work itself; a satire uses the work to comment on something else, so for Henley, this is a simple case: DeVore's videos do not comment on Henley's songs but use Henley's songs to mock Boxer. DeVore argues that his videos do indeed target Henley, who has long been identified with liberal and Democratic causes, and asserts that the campaign chose to use Henley's songs for precisely that reason. 'DeVore's videos target Henley only in the loosest sense,' writes Sheffner, 'and his brief's arguments ... sound dangerously close to the post hoc rationalizations dismissed as "pure shtick" and "completely unconvincing" by the Ninth Circuit in Dr. Seuss Enters. v. Penguin Books USA, Inc., 109 F.3d 1394 (1997).' The case also bears directly on the recent removal of the 'Downfall' clips from YouTube where many journalists have almost automatically labeled the removed videos 'parodies' while the vast majority aren't, says Sheffner." -
Cleaner Air Could Speed Global Warming
Hugh Pickens writes "Scientists estimate that the US Clean Air Act has cut a major air pollutant, sulfate aerosols, by 30% to 50% since the 1980s, helping greatly reduce cases of asthma and other respiratory problems. But NPR reports that this good news may have a surprising downside: cleaner air might actually intensify global warming. One benefit of sulfates is that they've been helpfully blocking sunlight from striking the Earth for many decades, by brightening clouds and expanding their coverage. Researchers believe greenhouse gases such as CO2 have committed the Earth to an eventual warming of roughly 4 degrees Fahrenheit, a quarter of which the planet has already experienced. But thanks to cooling by aerosols starting in the 1940s, the planet has felt only a portion of that warming. And unlike CO2, which persists in the atmosphere for centuries, aerosols last in the air for a week at most, so cutting them would probably rapidly accelerate global warming. The author of 'Hack the Planet' says: 'As we take away that unexpectedly helpful cooling mask, we're going to be facing more global warming than we expected.'" -
EyeDriver Lets Drivers Steer Car With Their Eyes
Hugh Pickens writes "NPR reports that German researchers have tested a new technology called eyeDriver that tracks a driver's eye movement and, in turn, steers the car in whatever direction they're looking at speeds up to 31 mph. 'The next step will be to get it to drive 60 miles per hour,' says Raul Rojas, an artificial intelligence researcher at Berlin's Free University. A Dodge Caravan fitted with eyeDriver has been tested on the tarmac at an abandoned airport at Tempelhof Airport. However, it remains unclear when — or if — the technology will be commercialized, as questions about safety and practicability abound: What about looking at a cute girl next to the road for a few seconds? Not to mention taking phone calls or typing a text while driving. But the researchers have an answer to distracted drivers: 'The Spirit of Berlin' is also an autonomous car equipped with GPS navigation, scores of cameras, lasers, and scanners that enable it to drive by itself. And should the technology-packed vehicle have a major bug, there's still an old fashioned way of stopping it. Two big external emergency buttons at the rear of the car allow people outside to shut down all systems." -
Ham Radio Still Growing In the iStuff Age
vhfer writes "From NPR comes this story about old-school communications in the age of Twitter: 'Only a few years ago, blogs listed ham radio alongside 35 mm film and VHS tape as technologies slated to disappear. They were wrong. Nearly 700,000 Americans have ham radio licenses — up 60 percent from 1981, a generation ago. And the number is growing.' The article goes on to say that while there's plenty of 60-plus year old hams, there's also a growing contingent of teens. I just met a 14-year-old, licensed in 2009. Getting rid of the Morse Code requirement sure helped in that regard. So does the fact that the test questions (and the answers) are freely available, legally, on the Internet. Study, take the test, hang the license certificate on the wall. Your geek cred gets an immediate boost. And who knows? Maybe the next time there's a Haiti-earthquake-sized disaster, you'll be one of the thousands of ham volunteers who provided the only communications in/out of Haiti for weeks following the quake, not to mention all of the tactical comms the country had for nearly a month." -
Astronaut Careers May Stall Without the Shuttle
Hugh Pickens writes "NPR reports that former shuttle commander Chris Ferguson now moonlights as a drummer for MAX Q, a classic rock band comprised solely of astronauts. 'Perhaps we'll have some more time to practice here once the shuttle program comes to a slow end,' says Ferguson, raising the question — what does the future hold for NASA's elite astronaut corps after the agency mothballs its aging space shuttles in the coming months? NASA currently has about 80 active astronauts, as well as nine new astronaut candidates hired last year. But there will be fewer missions after the shuttle program ends, and those will be long-duration stays at the space station. When the Apollo program ended, astronauts had to wait years before the space shuttles were ready to fly, but the situation was different back then. Space historian Roger Launius says, 'Even before the end of the Apollo program, NASA had an approved, follow-on program — the space shuttle — and a firm schedule for getting it completed.' These days, no one knows what NASA will be doing next. Meanwhile, private companies are moving forward with their efforts, raising the possibility of astronauts for hire. NASA administrator and former astronaut Charlie Bolden talked about that prospect earlier this year, saying it would be a different approach for NASA to rent not just the space vehicle, but also a private crew of astronauts to go with it. 'When we talk about going to distant places like Mars, the moon, [or] an asteroid, we will not be able to take someone off the street, train them for a few weeks and expect them to go off and do the types of missions we will demand of them,' said Bolden." -
White House Issues New Gas Mileage Standards
Hugh Pickens writes "NPR reports that the Obama administration has signed off on the nation's first rules on greenhouse gas emissions and set new fuel standards to meet a fleet-wide average of 35.5 mpg that will raise current standards by nearly 10 mpg by the 2016 model year. Although the new requirements would add an estimated $434 per vehicle in the 2012 model year and $926 per vehicle by 2016, drivers could save as much as $3,000 over the life of a vehicle through better gas mileage, according to a government statement. 'We will be helping American motorists save money at the pump, while putting less pollution in the air,' says Transportation Secretary Ray LaHood. Dave McCurdy, leader of the Alliance of Automobile Manufacturers, a trade group representing 11 automakers, says the industry supports a single national standard for future vehicles. 'Today, the federal government has laid out a course of action through 2016, and now we need to work on 2017 and beyond.' As the auto industry seeks to emerge from ashes, many manufacturers already are trying for the right mix of approaches, experts say. Some will try to sell more hybrids. Others are introducing not-so-gas-guzzling SUVs. They may also push slightly downsized and small cars, such as the Ford Fiesta." -
House of Commons Finds No Evidence of Tampering In Climate E-mails
dwguenther writes "The first of several British investigations into the e-mails leaked from one of the world's leading climate research centers has largely vindicated the scientists involved. The House of Commons' Science and Technology Committee said Wednesday that they'd seen no evidence to support charges that the University of East Anglia's Climatic Research Unit ... had tampered with data or perverted the peer review process to exaggerate the threat of global warming." According to the article, the head of committee which produced the report "said the lawmakers had been in a rush to publish something before Britain's next national election, which is widely expected in just over a month's time"; two further inquiries are to examine the issue more closely. The "e-mails appeared to show scientists berating skeptics in sometimes intensely personal attacks, discussing ways to shield their data from public records laws, and discussing ways to keep skeptics' research out of peer-reviewed journals," but the committee concluded that East Anglia researcher Phil Jones was not part of a conspiracy to hide evidence that weakens the case for global warming. -
The Death of the US-Mexico Virtual Fence
eldavojohn writes "A couple of years ago it was announced that the Boeing-built virtual fence at the US-Mexico border didn't work. Started in 2006, SBInet has been labeled a miserable failure and finally halted. A soon-to-be-released GAO report is expected to be overwhelmingly critical of SBInet, causing DHS Chief Janet Napolitano to announce yesterday that funding for the project has been frozen. It's sad that $1.4 billion had to be spent on the project before the discovery that this poorly conceived idea would not work." -
An Exercise To Model a "Solar Radiation Katrina"
Hugh Pickens writes in with an update on the warnings we discussed a year back about the dangers of a "solar Katrina." Now NPR is reporting on a tabletop exercise mounted in Boulder, Colorado by government workers attempting to model the effects of a worst-case solar electromagnetic storm. "...an exercise held in Boulder, Colorado, has investigated what might happen if the Earth were struck by a solar storm as intense as the huge storms that occurred in 1921 and 1859 — a sort of solar Katrina — and researchers found that the impact is likely to be far worse than in previous solar storms because of our growing dependence on satellites and other electronic devices that are vulnerable to electromagnetic radiation. 'In many ways, the impact of a major solar storm resembles that of a hurricane or an earthquake,' says FEMA Administrator Craig Fugate, except that a solar Katrina would cause damage in a much larger area — power could be knocked out almost simultaneously in countries from Sweden to Canada and the US. In the exercise, the first sign of trouble came when radiation began disrupting radio signals and GPS devices, says Tom Bogdan, who directs the Space Weather Prediction Center. Ten or 20 minutes later electrically charged particles 'basically took out' most of the commercial satellites that transmit telephone conversations, TV shows, and huge amounts of data we depend on in our daily lives. But the worst damage came nearly a day later, when the solar storm began to induce electrical currents in high voltage power lines strong enough to destroy transformers around the globe, leaving millions of people in northern latitudes without power." -
Beliefs Conform To Cultural Identities
DallasMay writes "This article describes an experiment that demonstrates that people don't put as much weight on facts as they do their own belief about how the world is supposed to work. From the article: 'In one experiment, Braman queried subjects about something unfamiliar to them: nanotechnology — new research into tiny, molecule-sized objects that could lead to novel products. "These two groups start to polarize as soon as you start to describe some of the potential benefits and harms," Braman says. The individualists tended to like nanotechnology. The communitarians generally viewed it as dangerous. Both groups made their decisions based on the same information. "It doesn't matter whether you show them negative or positive information, they reject the information that is contrary to what they would like to believe, and they glom onto the positive information," Braman says.'" -
A Warming Planet Can Mean More Snow
Ponca City, We love you writes "NPR reports that with snow blanketing much of the country, the topic of global warming has become the butt of jokes; but for scientists who study the climate, there's no contradiction between a warming world and lots of snow. 'The fact that the oceans are warmer now than they were, say, 30 years ago means there's about on average 4 percent more water vapor lurking around over the oceans than there was... in the 1970s,' says Kevin Trenberth, a prominent climate scientist. 'So one of the consequences of a warming ocean near a coastline like the East Coast and Washington, DC, for instance, is that you can get dumped on with more snow partly as a consequence of global warming.' Increased snowfall also fits a pattern suggested by many climate models, in which rising temperatures increase the amount of atmospheric moisture, bringing more rain in warmer conditions and more snow in freezing temperatures." -
The Ultimate Interstellar Valentine Mix Tape
Hugh Pickens writes "NPR reports that toward the end of the summer of 1977, NASA launched two Voyager spacecraft that each included a golden record containing, among other things, the sound of a kiss, a mother's first words to her newborn child, music from all over the world, and greetings in 59 different languages. The records on board were meant to survive for a billion years, in the hope that some day, against enormous odds, they might cross paths with an alien civilization. The record was a special project of Carl Sagan with the help of Ann Druyan, creative director of the project. For Druyan, though, the summer of 1977 and the Voyager project carry a deeply personal meaning because it was during the Voyager project that she and Sagan fell in love. Then Druyan had an idea for the record: They could measure the electrical impulses of a human brain and nervous system, turn it into sound, and put it on the record so that maybe, 1,000 million years from now, some alien civilization might be able to turn that data back into thoughts." (More, below.) "Just a few days after she and Sagan declared their love for each other, Druyan went to Bellevue Hospital in New York City and meditated while the sounds of her brain and body were recorded. According to Druyan, part of what she was thinking during that meditation was about 'the wonder of love, of being in love.' And the gold records? They're still out there with their offer, to whomever might stumble across them, of a human body newly in love. 'Whenever I'm down, ' says Druyan, 'I'm thinking: And still they move, 35,000 miles an hour, leaving our solar system for the great open sea of interstellar space.'" -
Gov't Proposes "National Climate Service" For the US
Standing Bear writes "NPR reports that 140 years after the creation of the National Weather Service, the US government is proposing the creation of a similar service that will provide long-term projections of how climate will change. 'We are actually getting millions of requests a year already about: How should coastal cities plan for sea-level rise? How should various other agencies in the federal government or in state governments make plans for everything from roads to managing water supplies?' says NOAA Administrator Dr. Jane Lubchenco. 'And a lot of that is going to be changing as the climate changes.' Under the plan, the new NOAA Climate Service would incorporate some of the agency's existing laboratories and research programs, including the National Climatic Data Center, the Geophysical Fluid Dynamics Laboratory and the National Weather Service's Historical Climate Network. Meanwhile, as plans for the new climate service shape up, NOAA launched a new Web site, climate.gov, designed to provide access to a wide range of climate information." -
Israeli Scientists Freeze Water By Warming It
ccktech writes "As reported by NPR and Chemistry world, the journal Science has a paper by David Ehre, Etay Lavert, Meir Lahav, and Igor Lubomirsky [note: abstract online; payment required to read the full paper] of Israel's Weizmann Institute, who have figured out a way to freeze pure water by warming it up. The trick is that pure water has different freezing points depending on the electrical charge of the surface it resides on. They found out that a negatively charged surface causes water to freeze at a lower temperature than a positively charged surface. By putting water on the pyroelectric material Lithium Tantalate, which has a negative charge when cooler but a positive change when warmer; water would remain a liquid down to -17 degrees C., and then freeze when the substrate and water were warmed up and the charge changed to positive, where water freezes at -7 degrees C." -
Why Time Flies By As You Get Older
Ant notes a piece up on WBUR Boston addressing theories to explain the universal human experience that time seems to pass faster as you get older. Here's the 9-minute audio (MP3). Several explanations are tried out: that brains lay down more information for novel experiences; that the "clock" for nerve impulses in aging brains runs slower; and that each interval of time represents a diminishing fraction of life as we age. -
DIY Texting System For Really Underground Radio
Gulthek writes "Sixteen-year-old Alexander Kendrick has created a device that allows texting and other data transfer from almost 1000 feet underground. The tech could allow rapid emergency communication with the surface and opens the potential for scientific measurements without the need to continually visit (and disturb) the cave environment." There's some kvetching in the NPR story's comments that it's not the first use of cave radios, but that seems to miss the point. -
Designing the Computer UIs In Movies
xandroid points out an NPR interview with Mark Coleran, who "...designs the fancy-but-fake graphics that flash across computers in the movies. He has worked on a laundry list of blockbusters: The Bourne Identity, The Bourne Ultimatum, Children of Men, Mission Impossible III, and many more. He says a lot of the inspiration for computer screens comes from video games." The main point of these fake movie UIs is different than that of real UIs: to tell a story very quickly, not to reveal and enable function. -
Ants That Can Count
thisIsOdd writes "NPR had a recent report about scientists at the University of Ulm who suggest that ants in desert environments count to help them get to and from their homes. Because the desert's windiness and sandiness is not conducive the 'smell-trail' method, where ants squeeze certain glands that leave a chemical trail, scientists were puzzled by the fact that these desert ants were able to leave and successfully return to their nest. The theory is called the 'pedometer theory,' and the experiment used to test it involves manipulating the leg length of some of these ants. Ants with longer legs would pass the nest on the way home, and ones with shorter legs came up... well... short." -
NASA Attempts To Assuage 2012 Fears
eldavojohn writes "The apocalyptic film 2012 has dominated the box office, taking in $65 million on opening weekend. But with all those uninformed eyeballs watching the film, NASA has found itself answering so many common questions that their Ask an Astrobiologist blog offers calming, professional reassurance that there is no planet Nibiru, nor will it collide with Earth (although I do recall a massive solar storm forecast). NASA's main site even offers a FAQ answering similar questions. NPR has more on NASA scientist David Morrison and his efforts to calm the ensuing public hysteria, but survivalists are already planning for the big one. Pretty funny, right? Not according to Morrison: 'I've had three from young people saying they were contemplating committing suicide. I've had two from women contemplating killing their children and themselves. I had one last week from a person who said, "I'm so scared, my only friend is my little dog. When should I put it to sleep so it won't suffer?" And I don't know how to answer those questions.'" -
Obama Talks Internet Freedom, China Censors
eldavojohn writes "In a town-hall-style Q&A with (hand-picked) Chinese students in Shanghai, President Obama made several statements knocking China's firewall and censorship. Quoting: 'I am a big believer in technology and I'm a big believer in openness when it comes to the flow of information. I think that the more freely information flows, the stronger the society becomes, because then citizens of countries around the world can hold their own governments accountable. They can begin to think for themselves. That generates new ideas. It encourages creativity. And so I've always been a strong supporter of open Internet use. I'm a big supporter of non-censorship. This is part of the tradition of the United States that I discussed before, and I recognize that different countries have different traditions. I can tell you that in the United States, the fact that we have free Internet — or unrestricted Internet access — is a source of strength, and I think should be encouraged.' The Washington Post notes that the event was broadcast only on the local level, and in fact Chinese authorities removed from view what little coverage it had gotten, after about an hour. But at least American news media are gobbling it up." -
Cooking May Have Made Us Human
SpaceGhost writes "Anthropologist Richard Wrangham, author of Catching Fire: How Cooking Made Us Human believes that the discovery of cooked food led to evolutionary changes resulting in a smaller and different digestive system based on a higher-quality diet, mainly relying on cooked meat. In an interview on NPR's Science Friday (text and audio), Professor Wrangham explores concepts such as the digestive costs of food, the benefits (or lack thereof) of raw diets, and a distinct preference in Great Apes for cooked food over raw." -
Progress In Brain-Based Lie Detection
A Cognitive Neuroscientist writes "A new study, led by Harvard Psychologist Joshua Greene and forthcoming in the Proceedings of the National Academy of Sciences, may represent progress on the front of using brain imaging techniques, such as functional magnetic resonance imaging, to detect lies. According to Harvard's press release, Greene's is 'the first study to examine brain activity of people telling actual lies,' as opposed to prior studies in which subjects were merely instructed to lie. The results suggest that one key step in distinguishing honest from dishonest individuals may involve focusing on a small set of brain regions that are responsible for executive control and attention. However, given that the actual paper is yet to be published, it's unclear whether the study is prone to some of the methodological and interpretive complications that have recently plagued similar brain imaging studies." -
This Is Your Brain On Magnets — Or Maybe Not
conspirator23 writes "Jon Hamilton of National Public Radio brings us a story about 'voodoo correlations' in fMRI studies that seek to learn more about emotional states, personality, and social cognition in the human brain. Many of us outside the scientific community have been treated to fascinating images of brain activity and corresponding explanations about how the images reveal which portions of the brain are engaged in certain kinds of thinking. But these images are not actual snapshots; they are visualizations of data generated by repeated scans during experiments. Flaws in the statistical methods used by researchers can result in false images with a variety of inaccuracies. Yet the images produced are so vivid and engaging that even other neuroscientists can be misled by them." -
47th Mersenne Prime Confirmed
radiot88 writes to let us know that he heard a confirmation of the discovery of the 47th known Mersenne Prime on NPR's Science Friday (audio here). The new prime, 2^42,643,801 - 1, is actually smaller than the one discovered previously. It was "found by Odd Magnar Strindmo from Melhus, Norway. This prime is the second largest known prime number, a 'mere' 141,125 digits smaller than the Mersenne prime found last August. Odd is an IT professional whose computers have been working with GIMPS since 1996 testing over 1,400 candidates. This calculation took 29 days on a 3.0 GHz Intel Core2 processor. The prime was independently verified June 12th by Tony Reix of Bull SAS in Grenoble, France..." -
Parrots Can Dance
juuri sends in an NPR article about the consensus created among scientists that some birds actually dance to music. "The results of this study are reported in the journal Current Biology, along with another scientific paper inspired by YouTube videos of dancing animals. Adena Schachner is a graduate student in the psychology department of Harvard University. She says she was familiar with the idea that some people had made videos of birds supposedly dancing. ... She and her colleagues eventually analyzed more than 5,000 videos. 'Imagine watching YouTube eight hours a day for a month,' she says. 'That's pretty much what we did. It was amusing for perhaps the first couple of hours.'" juuri adds, "While this makes them somewhat unique in the animal world, as only three animals are now known to dance by verifiable proofs, what struck me more was that this was the first time YouTube had helped forge a new scientific understanding. Given the explosive growth of uploading videos and people watching them, what other new understandings and popular misconceptions will be proven or disproved due to this emerging media?" -
LoTR Fan Film — The Hunt For Gollum
stevedcc writes "This weekend sees the release of The Hunt for Gollum, a Lord of the Rings fan-film. It'll be available on the web for free. The BBC are running an article about the making of the film, with a budget of £3,000 (spent mostly on costumes and make-up). There were 160 contributors involved, many over the internet." I hope it lives up to the trailer (linked from the BBC story); the finished film is approximately 40 minutes. memoryhole supplies links to YouTube for both the full trailer and a second trailer. Reader jowifi adds a link to NPR's story on the film, writing, "NPR discussed the legality of this type of creation with EFF lawyer Fred Von Lohman, who said it's not clear if such a production violates the copyright for Tolkien's work."
