Churchill Accused of Sealing UFO Files, Fearing Public Panic 615

Newly released secret files show that Winston Churchill ordered a cover-up of an alleged encounter between a UFO and a RAF bomber because he feared public panic. From the article: "Mr Churchill is reported to have made a declaration to the effect of the following: 'This event should be immediately classified since it would create mass panic among the general population and destroy one's belief in the Church.'"

LCD 'Engine' For Spacecraft Attitude Control 95

Bruce Perens writes "Japan's IKAROS satellite, which earlier performed the first successful demonstration of a solar sail, has broken more new ground. Liquid-crystal displays — yes, like in your video monitor — were fabricated into strips on the edges of the solar sail. By energizing some of the LCDs and changing the reflective characteristics of parts of the sail from specular to diffuse, JAXA scientists successfully generated attitude control torque in the sail, changing the spacecraft's orientation."

Cool, Science-y Masters Programs For Software Devs? 150

An anonymous reader writes "I'm an early-30s software engineer with 10 years of development experience, and a BA in computer science from a top university. I've been working for several years at a national lab in bioinformatics, but I'm starting to wonder what other interesting directions there are to go for people in my boat: computer science majors with software development experience. The goal would be to find a position that could leverage my development skills, but also include a strong research component, without the need for a Ph.D. (I would be happy to get a masters for the right job.) I'm actually getting some of those things in my current job, but I'm ready to move on to new or different areas of research. Possible fields that seem interesting so far: neuroscience, economics/sociology, and AI. I'm happy to work in a team in support of Ph.D.s, but would like an active part in the research end of things as well as the tool-making end."

Why Being Wrong Makes Humans So Smart 311

Hugh Pickens sends in an excerpt in last week's Boston Globe from Kathryn Schulz's book Being Wrong: Adventures in the Margin of Error. "The more scientists understand about cognitive functioning, the more it becomes clear that our capacity to make mistakes is utterly inextricable from what makes the human brain so swift, adaptable, and intelligent. Rather than treating errors like the bedbugs of the intellect — an appalling and embarrassing nuisance we try to pretend out of existence — we need to recognize that human fallibility is part and parcel of human brilliance. Neuroscientists increasingly think that inductive reasoning undergirds virtually all of human cognition. Humans use inductive reasoning to learn language, organize the world into meaningful categories, and grasp the relationship between cause and effect. Thanks to inductive reasoning, we are able to form nearly instantaneous beliefs and take action accordingly. However, Schulz writes, 'The distinctive thing about inductive reasoning is that it generates conclusions that aren't necessarily true. They are, instead, probabilistically true — which means they are possibly false.' Schulz recommends that we respond to the mistakes (or putative mistakes) of those around us with empathy and generosity and demand that our business and political leaders acknowledge and redress their errors rather than ignoring or denying them. 'Once we recognize that we do not err out of laziness, stupidity, or evil intent, we can liberate ourselves from the impossible burden of trying to be permanently right. We can take seriously the proposition that we could be in error, without deeming ourselves idiotic or unworthy.'"

FAA Setting Up Commercial Spaceflight Center 113

coondoggie writes "The FAA this week took a step closer to setting up a central hub for the development of key commercial space transportation technologies such as space launch and traffic management applications and setting orbital safety standards. The hub, known as the Center of Excellence for Commercial Space Transportation, would have a $1 million yearly budget and tie together universities, industry players, and the government for cost-sharing research and development. The FAA expects the center to be up and running this year."

US Mobile Data Traffic Usage Exceeds Voice 71

MojoKid writes "A report just released states that total mobile data traffic topped mobile voice traffic in the United States last year, for the first time. In fact, globally, data traffic topped voice traffic on a monthly basis last year, and the total traffic across the world exceeded an exabyte for the first time in 2009. Apparently, North America and Western Europe's mobile data markets are growing so rapidly they each should exceed an exabyte sometime in 2010. Interestingly, the nations with the largest data service revenues were: the US, Japan, China, the UK, Italy, Germany, France, Australia, Spain and Korea, respectively."

Balloon and Duct Tape Deliver Great Space Photos 238

krou writes "With a budget of £500, Robert Harrison used cheap parts, a weather balloon, some duct tape, a digital camera, and a GPS device to capture some great photos of the earth from space that resulted in NASA calling him to find out how he had done it. 'A guy phoned up who worked for NASA who was interested in how we took the pictures,' said Mr Harrison. 'He wanted to know how the hell we did it. He thought we used a rocket. They said it would have cost them millions of dollars.' The details of his balloon are as follows: he used 'an ordinary Canon camera mounted on a weather balloon,' 'free software' that 'reprogrammed the camera to wake up every five minutes and take eight photographs and a video before switching off for a rest.' He also ensured the camera was 'wrapped in loft insulation' to make sure it could operate at the cold temperatures. The GPS device allowed him to pinpoint the balloon's location, and retrieve the camera when it fell down to earth attached to a small parachute."
