    "Project Gustav is a realistic painting-system prototype that enables artists to become immersed in the digital painting experience. It achieves interactivity and realism by leveraging the computing power of modern GPUs, taking full advantage of multitouch and tablet input technology and our novel natural media-modeling and brush-simulation algorithms. Project Gustav is a great example of how Microsoft's research efforts are leading to exciting new technologies to support creativity. About Typically the experience of painting on a computer is nothing like painting in the real world. Real painting is actually a very complex phenomenon - a 3D brush consisting of thousands of individually deforming bristles, interacting with viscous fluid paint and a rough-surfaced canvas to create rich, complex strokes. Until fairly recently, the amount of computing power available on a typical home computer simply hasn't been sufficient to attempt simulating such a real-world painting experience in any detail. Project Gustav aims to leverage the increasing power of the PC and ever faster graphics processors and combine that with a natural user interface, to bring a rich painting experience to a wide audience including hobbyists and professionals alike. The result is a prototype system that contains some of the world's most advanced algorithms for natural painting.

Belief In Climate Change Hinges On Worldview : NPR - 0 views

  • "People tend to conform their factual beliefs to ones that are consistent with their cultural outlook, their world view," Braman says. The Cultural Cognition Project has conducted several experiments to back that up. Participants in these experiments are asked to describe their cultural beliefs. Some embrace new technology, authority and free enterprise. They are labeled the "individualistic" group. Others are suspicious of authority or of commerce and industry. Braman calls them "communitarians." In one experiment, Braman queried these 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.
  • "Basically the reason that people react in a close-minded way to information is that the implications of it threaten their values," says Dan Kahan, a law professor at Yale University and a member of The Cultural Cognition Project. Kahan says people test new information against their preexisting view of how the world should work. "If the implication, the outcome, can affirm your values, you think about it in a much more open-minded way," he says. And if the information doesn't, you tend to reject it. In another experiment, people read a United Nations study about the dangers of global warming. Then the researchers told the participants that the solution to global warming is to regulate industrial pollution. Many in the individualistic group then rejected the climate science. But when more nuclear power was offered as the solution, says Braman, "they said, you know, it turns out global warming is a serious problem."And for the communitarians, climate danger seemed less serious if the only solution was more nuclear power.

  • Then there's the "messenger" effect. In an experiment dealing with the dangers versus benefits of a vaccine, the scientific information came from several people. They ranged from a rumpled and bearded expert to a crisply business-like one. The participants tended to believe the message that came from the person they considered to be more like them. In relation to the climate change debate, this suggests that some people may not listen to those whom they view as hard-core environmentalists. "If you have people who are skeptical of the data on climate change," Braman says, "you can bet that Al Gore is not going to convince them at this point." So, should climate scientists hire, say, Newt Gingrich as their spokesman? Kahan says no. "The goal can't be to create a kind of psychological house of mirrors so that people end up seeing exactly what you want," he argues. "The goal has to be to create an environment that allows them to be open-minded."And Kahan says you can't do that just by publishing more scientific data.

    "It's a hoax," said coal company CEO Don Blankenship, "because clearly anyone that says that they know what the temperature of the Earth is going to be in 2020 or 2030 needs to be put in an asylum because they don't." On the other side of the debate was environmentalist Robert Kennedy, Jr. "Ninety-eight percent of the research climatologists in the world say that global warming is real, that its impacts are going to be catastrophic," he argued. "There are 2 percent who disagree with that. I have a choice of believing the 98 percent or the 2 percent." To social scientist and lawyer Don Braman, it's not surprising that two people can disagree so strongly over science. Braman is on the faculty at George Washington University and part of The Cultural Cognition Project, a group of scholars who study how cultural values shape public perceptions and policy

Research: How you think about your age may affect how you age - 0 views

  • "How old you are matters, but beyond that it's your interpretation that has far-reaching implications for the process of aging," said Markus H. Schafer, a doctoral student in sociology and gerontology who led the study. "So, if you feel old beyond your own chronological years you are probably going to experience a lot of the downsides that we associate with aging. "But if you are older and maintain a sense of being younger, then that gives you an edge in maintaining a lot of the abilities you prize." Schafer and co-author Tetyana P. Shippee, a Purdue graduate who is a research associate at Purdue's Center on Aging and the Life Course, compared people's chronological age and their subjective age to determine which one has a greater influence on cognitive abilities during older adulthood. Nearly 500 people ages 55-74 were surveyed about aging in 1995 and 2005 as part of the National Survey of Midlife Development in the United States. In 1995, when people were asked what age do you feel most of the time, the majority identified with being 12 years younger than they actually were. "We found that these people who felt young for their age were more likely to have greater confidence about their cognitive abilities a decade later," Schafer said. "Yes, chronological age was important, but the subjective age had a stronger effect. "What we are not sure about is what comes first. Does a person's wellness and happiness affect their cognitive abilities or does a person's cognitive ability contribute to their sense of wellness. We are planning to address this in a future study."

Link Found Between Golden Ratio and Atomic Symmetry - 2 views

  • Researchers in Germany and the UK have discovered symmetry hidden in solid state matter at very small scales. The findings, published in the journal Science, indicate that symmetry involves the golden ratio famous from art and architecture. The research was supported in part by the NMI3 ('Integrated infrastructure initiative for neutron scattering and muon spectroscopy') project, which was funded under the 'Coordination of research activities' Thematic area of the EU's Sixth Framework Programme (FP6) to the tune of EUR 21 million
  • Scientists say that in mathematics and the arts, two quantities are in the golden ratio if the ratio of the sum of the quantities to the larger quantity is the same as the ratio of the larger quantity to the smaller one.
  • 'Such discoveries are leading physicists to speculate that the quantum, atomic scale world may have its own underlying order,' Professor Tennant, who led the HZB team, said, adding that 'similar surprises may await researchers in other materials in the quantum critical state.

Darkness increases dishonest behavior - 0 views

  •  
    "Darkness can conceal identity and encourage moral transgressions; thus Ralph Waldo Emerson wrote in "Worship" in The Conduct of Life (1860), "as gaslight is the best nocturnal police, so the universe protects itself by pitiless publicity." New research in Psychological Science, a journal of the Association for Psychological Science, shows that darkness may also induce a psychological feeling of illusory anonymity, just as children playing "hide and seek" will close their eyes and believe that other cannot see them, the experience of darkness, even one as subtle as wearing a pair of sunglasses, triggers the belief that we are warded from others' attention and inspections."

Clever folds in a globe give new perspectives on Earth - tech - 10 December 2009 - New ... - 0 views

  •  
    "Video: A new way to unfold the Earth's surface produces a new kind of map A new technique for unpeeling the Earth's skin and displaying it on a flat surface provides a fresh perspective on geography, making it possible to create maps that string out the continents for easy comparison, or lump together the world's oceans into one huge mass of water surrounded by coastlines. See a gallery of the new maps "Myriahedral projection" was developed by Jack van Wijk, a computer scientist at the Eindhoven University of Technology in the Netherlands. "The basic idea is surprisingly simple," says van Wijk. His algorithms divide the globe's surface into small polygons that are unfolded into a flat map, just as a cube can be unfolded into six squares. Cartographers have tried this trick before; van Wijk's innovation is to up the number of polygons from just a few to thousands. He has coined the word "myriahedral" to describe it, a combination of "myriad" with "polyhedron", the name for polygonal 3D shapes. Warping reality The mathematical impossibility of flattening the surface of a sphere has long troubled mapmakers. "Consider peeling an orange and trying to flatten it out," says van Wijk. "The surface has to distort or crack." Some solutions distort the size of the continents while roughly preserving their shape - the familiar Mercator projection, for instance, makes Europe and North America disproportionately large compared with Africa. Others, like the Peters projection, keep landmasses at the correct relative sizes, at the expense of warping their shapes. An ideal map would combine the best properties of both, but that is only possible by inserting gaps into the Earth's surface, resulting in a map with confusing interruptions. Van Wijk's method makes it possible to direct those cuts in a way that minimises such confusion. Maps of significance When generating a map he assigns a "weighting" to each edge on the polyhedron to signal its importance, influencing the pl

Russia May Send Spacecraft to Deflect Incoming Asteroid : Discovery News - 0 views

  •  
    "Russia is considering sending a spacecraft to a large asteroid to knock it off its path and prevent a possible collision with Earth, the head of the country's space agency said Wednesday. Anatoly Perminov said the space agency will hold a meeting soon to assess a mission to Apophis, telling Golos Rossii radio that it would invite NASA, the European Space Agency, the Chinese space agency and others to join the project once it is finalized. When the 270-meter (885-foot) asteroid was first discovered in 2004, astronomers estimated the chances of it smashing into Earth in its first flyby in 2029 were as high as 1-in-37, but have since lowered their estimate. Further studies ruled out the possibility of an impact in 2029, when the asteroid is expected to come no closer than 18,300 miles (29,450 kilometers) above Earth's surface, but they indicated a small possibility of a hit on subsequent encounters. In October, NASA lowered the odds that Apophis could hit Earth in 2036 from a 1-in-45,000 as earlier thought to a 1-in-250,000 chance after researchers recalculated the asteroid's path. It said another close encounter in 2068 will involve a 1-in-330,000 chance of impact. Without mentioning NASA findings, Perminov said that he heard from a scientist that Apophis is getting closer and may hit the planet. "I don't remember exactly, but it seems to me it could hit the Earth by 2032," Perminov said. "People's lives are at stake. We should pay several hundred million dollars and build a system that would allow to prevent a collision, rather than sit and wait for it to happen and kill hundreds of thousands of people," Perminov said. Scientists have long theorized about asteroid deflection strategies. Some have proposed sending a probe to circle around a dangerous asteroid to gradually change its trajectory. Others suggested sending a spacecraft to collide with the asteroid and alter its momentum, or using nuclear weapons to hit it."

Technology Review: Mapping the Malicious Web - 1 views

  • Now a researcher at Websense, a security firm based in San Diego, has developed a way to monitor such malicious activity automatically. Speaking at the RSA Security Conference in San Francisco last week, Stephan Chenette, a principal security researcher at Websense, detailed an experimental system that crawls the Web, identifying the source of content embedded in Web pages and determining whether any code on a site is acting maliciously. Chenette's software, called FireShark, creates a map of interconnected websites and highlights potentially malicious content. Every day, the software maps the connections between nearly a million websites and the servers that provide content to those sites. "When you graph multiple sites, you can see their communities of content," Chenette says. While some of the content hubs that connect different communities could be legitimate--such as the servers that provide ads to many different sites--other sources of content could indicate that an attacker is serving up malicious code, he says. According to a study published by Websense, online attackers' use of legitimate sites to spread malicious software has increased 225 percent over the past year.
  •  
    Over the past couple of years, cybercriminals have increasingly focused on finding ways to inject malicious code into legitimate websites. Typically they've done this by embedding code in an editable part of a page and using this code to serve up harmful content from another part of the Web. But this activity can be difficult to spot because websites also increasingly pull in legitimate content, such as ads, videos, or snippets of code, from outside sites.

Flightless mosquitoes developed to help control dengue fever - 0 views

  • Dengue fever causes severe flulike symptoms and is among the world's most pressing public health issues. There are 50 million to 100 million cases per year, and nearly 40 percent of the global population is at risk. The dengue virus is spread through the bite of infected female Aedes aegypti mosquitoes, and there is no vaccine or treatment. UCI researchers and colleagues from Oxitec Ltd. and the University of Oxford created the new breed. Flightless females are expected to die quickly in the wild, curtailing the number of mosquitoes and reducing - or even eliminating - dengue transmission. Males of the strain can fly but do not bite or convey disease. When genetically altered male mosquitoes mate with wild females and pass on their genes, females of the next generation are unable to fly. Scientists estimate that if released, the new breed could sustainably suppress the native mosquito population in six to nine months. The approach offers a safe, efficient alternative to harmful insecticides.

'Clash' of 3-D movies to hit underprepared cinemas - 0 views

  • The pileup was created in part because studios want to capture some of the excitement surrounding "Avatar," the James Cameron epic released in December. At $2.4 billion in global ticket sales, it is the highest-grossing film ever. In addition to the novelty or richer experience that might drive more people to see a 3-D movie, tickets to 3-D movies also cost a few dollars more. Around the time "Avatar" came out, Warner Bros. decided to convert a remake of "Clash of the Titans" from 2-D to 3-D and push its release back a week, to April 2. That will be the third 3-D movie to hit the market in a short span. DreamWorks Animation SKG Inc.'s "How to Train Your Dragon" comes out a week earlier, and The Walt Disney Co.'s "Alice in Wonderland" hits theaters March 5. And "Avatar" might still be playing in some places too. But a limited number of theaters can show these movies in 3-D, because not all theater owners have bought new digital projectors and undertaken other upgrades necessary to show movies in the format. About 3,900 to 4,000 3-D-ready screens are expected to be available in the U.S. and Canada by the end of March. Typically a movie in wide release might be shown on 3,000 to 10,000 screens in North America. In the past, a smaller number of 3-D-capable screens was adequate when one major film at a time was being released in 3-D in addition to 2-D. Each movie had a longer run, and moviegoers who wanted to see it in 3-D could pick a convenient time to go. With three out at once, each will get less exposure because some theaters with only one or two 3-D screens will have to choose which movies to show in 3-D. "One or all three are going to suffer in some way," said Patrick Corcoran, director of media and research for the National Association of Theatre Owners. "It makes it a much harder decision on exhibitors on what to keep or what to drop or what to add and probably should have been avoided."
  •  
    Movies in 3-D are becoming such big moneymakers that Hollywood studios are cramming them into the nation's theaters, even though there aren't enough screens available to give each film its fullest possible run. That will mean an unprecedented number of 3-D movies for film fans to choose from this spring, and smaller profits for Hollywood studios than they might otherwise get with fewer 3-D competitors.

mental_floss Blog » Extreme Weirdness: Antarctica's "Blood Falls" - 0 views

  • There is a glacier in Antarctica that seems to be weeping a river of blood. It’s one of the continent’s strangest features, and it’s located in one of the continent’s strangest places — the McMurdo Dry Valleys, a huge, ice-free zone and one of the world’s harshest deserts. So imagine you’re hiking through this – – which has been kept ice-less since God was a child because of something called the katabatic winds, which sweep over the valleys at up to 200 mph and suck all the moisture out of them. Anyway, you’re hiking along, passing dessicated penguin carcasses and such, and you come to this. A bleeding glacier. Discovered in 1911 by a member of Robert Scott’s ill-fated expedition team, its rusty color was at first theorized to be caused by some sort of algae growth. Later, however, it was proven to be due to iron oxidation. Every so often, the glacier spews forth a clear, iron-rich liquid that quickly oxidizes and turns a deep shade of red. According to Discover Magazine – The source of that water is an intensely salty lake trapped beneath 1,300 feet of ice, and a new study has now found that microbes have carved out a niche for themselves in that inhospitable environment, living on sulfur and iron compounds. The bacteria colony has been isolated there for about 1.5 million years, researchers say, ever since the glacier rolled over the lake and created a cold, dark, oxygen-poor ecosystem. Even weirder: scientists think that the bacteria responsible for Blood Falls might be an Earth-bound approximation of the kind of alien life that might exist elsewhere in the solar system, like beneath the polar ice caps of Mars and Europa.

Feds charge trendy sushi restaurant for serving whale meat - CNN.com - 0 views

  • The misdemeanor charge carries a federal prison sentence of up to a year and a fine of up to $200,000 for the company, said Thom Mrozek, spokesman for the U.S. Attorney's Office. Lawyers for Typhoon could not be reached for comment. But the restaurant told the Los Angeles Times it accepts responsibility and will pay a fine. The investigation began in October when two members of the team that made "The Cove" visited The Hump, officials said. "The Cove," which exposes the annual killing of dolphins at a Japanese fishing village, won the Academy Award for Best Documentary on Sunday. The restaurant, located at the Santa Monica Airport, is known for its exotic fare. Its Web site asks diners to surrender themselves to its chefs for "a culinary adventure ... unlike any that you have previously experienced." Armed with a hidden camera, the two women captured the waitress serving them whale and horse meat and identifying them as such, a federal criminal complaint said. A receipt from the restaurant at the end of the meal identified their selection as "whale" and "horse" with the cost -- $85 -- written next to them. The women snuck pieces of the meat into a napkin and later sent them for examination to a researcher at Oregon State University. He identified the whale sample to be that of sei whale, prosecutors said.

    Federal authorities have charged a trendy Santa Monica sushi restaurant with serving whale meat -- an investigation that was spurred by the team behind the Oscar-winning documentary, "The Cove." Prosecutors charged Typhoon Restaurant Inc., the parent company of The Hump, and one of its chefs -- Kiyoshiro Yamamoto, 45 -- with the illegal sale of a marine mammal product for an unauthorized purpose. While it is considered a delicacy in Japan and some other countries, meat from whale -- an endangered species -- is illegal to consume in the United States.

  • "Haptics is far from a mature technology, and this project was one of the first to build a haptic system for industrial designers," Bordegoni notes. The multimodal and multisensory SATIN system consists of two FCS-HapticMASTER devices, in essence robotic arms more commonly used for remote welding or dental surgery, which position and rotate a robotic spline, an electronic version of the flexible strip of material, typically wood or metal, long used by designers to draw curves. Fitted with actuators and sensors, the spline automatically twists and bends to the shape of a digital representation of the product uploaded by the designer into the system.
