Roland Piquepaille points out a news release from the University of Michigan where researchers are looking to birds and bats for insights into aerospace engineering. Wei Shyy and his colleagues are learning from solutions developed by nature and applying them to the technology of flight. A presentation on this topic was also given at the 2005 TED conference. From the news release: "The roll rate of the aerobatic A-4 Skyhawk plane is about 720 degrees per second. The roll rate of a barn swallow exceeds 5,000 degrees per second. Select military aircraft can withstand gravitational forces of 8-10 G. Many birds routinely experience positive G-forces greater than 10 G and up to 14 G. Flapping flight is inherently unsteady, but that's why it works so well. Birds, bats and insects fly in a messy environment full of gusts traveling at speeds similar to their own. Yet they can react almost instantaneously and adapt with their flexible wings."

GoSun wrote in with an article about new solar panels that opens, "Sunlight has never really caught fire as a power source, mostly because generating electricity with solar cells is more expensive and less efficient than some conventional sources. But a new solar panel unveiled this month by the Georgia Tech Research Institute hopes to brighten the future of the energy source." The new panels are able to produce sixty times the current of traditional models.

Madas writes "Scientists working in Cambridge have managed to make quantum encryption completely secure (registration required) by putting decoy pulses in the key transmission stream. According to the story this paves the way for safe, encrypted high-speed data links. Could this allow completely private transmission of data away from snooping eyes and ears? Or will it mean film studios can stop movies from being copied when traveling on the internet?"

Milwaukee's_Best writes "Skype has just asked the FCC to force wireless phone companies to open their networks to all comers. Skype essentially wants to turn the wireless phone companies into just another network of the kind currently operated on the ground. This would require carriers to allow any phone to be used on their networks, and for any application. Users would simply purchase a voice or data plan (though these could easily converge into a data plan if VoIP calling is used) and then use the device of their choice to access the network of their choice. Think of it as network neutrality for cell networks. Given the competition that exists within the industry, is this needed?"

musicon writes "A group of scientists at Purdue University have created a portable refinery that efficiently converts food, paper, and plastic trash into electricity. The machine, designed for the U.S. military, would allow soldiers in the field to convert waste into power. It could also have widespread civilian applications in the future. Researchers tested the first tactical biorefinery prototype in November and found that it produced approximately 90 percent more energy than it consumed."

Giorgio Maone writes "The New York Times article 'Tips for Protecting the Home Computer' follows a story we recently discussed about the proliferation of botnets, and contains some statements which may sound quite unusual from mainstream press, especially if targeted to home users: 'Using a non-Windows-based PC may be one defense against these programs, known as malware ... Alternative browsers, like Firefox and Opera, may insulate users ... NoScript, a plug-in utility, can limit the ability of remote programs to run potentially damaging programs on your PC'."

shadowspar writes, "Recent restructuring and production cuts have left Lego unable to fill orders for the upcoming holiday season. Affected products include Duplo bricks, Lego City sets, and (horror of horrors!) Star Wars and Lego Technik sets." According to the article Lego stands to lose $127 million in holiday sales.

PadRacerExtreme writes "Vista includes the much maligned 'Genuine Advantage' layer inside, which ensures that your copy of the OS is legit. If you're running a non-validated copy you get no upgrades, no security protection, nothing. That's all well and good, but what happens if a cracker tweaks that Genuine Advantage layer for its own good? Dvorak sees a huge problem, just waiting to happen. What's the vulnerability?" From the article: "I suspect the policeman [WGA] will actually be hacked before the OS. It might actually be easier for the pirates to create a fake cop that constantly authenticates fake versions of Vista than it will be to create a Vista imitation that can pretend to be a legitimate version. There is some irony to that idea. But that's none of my concern. I'm more worried about some joker creating a virus or exploit that turns the good cop into a bad cop, and I can only imagine the destruction and hassle that will ensue."

Roland Piquepaille writes "Microreactors have already been used for on-site reforming of fuels, such as methanol or propane, to produce hydrogen to be used in fuel cells. Now, researchers at the University of Illinois at Urbana-Champaign (UIUC) have designed very efficient ceramic microreactors to do this task. The scientists say that their microreactors are much better than other fuel reformer systems. They are now trying to reform gasoline and diesel, which are more widely distributed than propane. Does this mean that one day we'll be able to go to a gas station to refill the fuel cells powering our laptops? Probably not before a while, but read more for additional details, references and a picture of a prototype."

dfenstrate writes "The latest New Scientist has an article about an engine that exploits relativity and microwaves to generate thrust. There is a working prototype." From the article: "Roger Shawyer has developed an engine with no moving parts that he believes can replace rockets and make trains, planes and automobiles obsolete ... The device that has sparked their interest is an engine that generates thrust purely from electromagnetic radiation — microwaves to be precise — by exploiting the strange properties of relativity. It has no moving parts, and releases no exhaust or noxious emissions. Potentially, it could pack the punch of a rocket in a box the size of a suitcase. It could one day replace the engines on almost any spacecraft. More advanced versions might allow cars to lift from the ground and hover."

avatar4d writes to mention an article on CIO about a new 'space race' on the internet between China and the U.S.. China is currently hard at work at what is being called the 'Chinese Next Generation Internet' (CNGI). With plans to unveil the project at the 2008 Beijing Olympics, the network is part of a plan to leap ahead of the United States in innovation and technology. From the article: "The strategy, outlined in China's latest five-year plan, calls for the country to transition its economy from one based almost entirely on manufacturing to one that produces its own scientific and technological breakthroughs — using a new and improved version of today's dominant innovation platform, the Internet. 'CNGI is the culmination of this revolutionary plan' to turn China into the world's innovation capital, says Wu Hequan, vice president of the Chinese Academy of Engineering and the chairman of the CNGI Expert Committee, the group overseeing the project. 'We will use it as a way to break through and be competitive in the global economic market.'"

Roland Piquepaille writes "French researchers have found that Egyptians, Greek and Romans were using nanotechnology to dye their hair several thousands years ago. Nanowerk Spotlight reports they were using lead compounds which generated lead sulfide (PbS) nanocrystals with a diameter of only 5 nanometers. At a moment where many people wonder if the use of nanoparticles is safe, it's good to know that nanotechnology has been widely used for a very long time."
