KPexEA (1030982) writes "Today, Geoffroy Kirstetter and buddies at the Universite de Nice Sophia-Antipolis in France ask what happens when a jet of liquid hits a soapy film.
These guys used a bowl of washing up liquid to generate a soap film some 10cm across in a wire frame. They then pumped a stream of soapy water through a sub-millimetre nozzle to create a jet with a size and velocity they could vary. Finally, they fired the jet at the film at various different angles to see what happens.
It turns out that the film is surprisingly robust. "Regardless of its velocity, radius and incident angle, the jet never breaks the soap lm," say Kirstetter and co.
But something else happens instead: the film bends the jet by an amount that depends on its angle of incidence. In effect, the film acts like a lens and Kirstetter and co are able to derive a kind of Snell-like law to describe this kind of refraction." Link to Original Source top
KPexEA (1030982) writes "Video-game players have solved a molecular puzzle that stumped scientists for years, and those scientists say the accomplishment could point the way to crowdsourced cures for AIDS and other diseases. The feat, which was accomplished using a collaborative online game called Foldit, is also one giant leap for citizen science — a burgeoning field that enlists Internet users to look for alien planets, decipher ancient texts and do other scientific tasks that sheer computer power can't accomplish as easily.
The monkey-virus puzzle was one of several unsolved molecular mysteries that a colleague of Khatib's at the university, Frank DiMaio, recently tried to solve using a method that took advantage of a protein-folding computer program called Rosetta. "This was one of the cases where his method wasn't able to solve it," Khatib said.
Fortunately, the challenge fit the current capabilities of the Foldit game, so Khatib and his colleagues put the puzzle out there for Foldit's teams to work on. "This was really kind of a last-ditch effort," he recalled. "Can the Foldit players really solve it?"

Game developer David Braben creates a USB stick PC
KPexEA (1030982) writes "Braben has developed a tiny USB stick PC that has a HDMI port in one end and a USB port on the other. You plug it into a HDMI socket and then connect a keyboard via the USB port giving you a fully functioning machine running a version of Linux. The cost? $25.
The hardware being offered is no slouch either. It uses a 700MHz ARM11 processor coupled with 128MB of RAM and runs OpenGL ES 2.0 allowing for decent graphics performance with 1080p output confirmed. Storage is catered for by an SD card slot. It also looks as though modules can be attached such as the 12MP camera seen in the image above.
We can expect it to run a range of Linux distributions, but it looks like Ubuntu may be the distro it ships with. That means it will handle web browsing, run office applications, and give the user a fully functional computer to play with as soon as it’s plugged in. All that and it can be carried in your pocket or on a key chain." Link to Original Source top
New engine sends shock waves through auto industry
KPexEA (1030982) writes "Researchers at Michigan State University have built a prototype gasoline engine that requires no transmission, crankshaft, pistons, valves, fuel compression, cooling systems or fluids. Their so-called Wave Disk Generator could greatly improve the efficiency of gas-electric hybrid automobiles and potentially decrease auto emissions up to 90 percent when compared with conventional combustion engines.
The Wave Disk Generator uses 60 percent of its fuel for propulsion; standard car engines use just 15 percent. As a result, the generator is 3.5 times more fuel efficient than typical combustion engines.
Researchers estimate the new model could shave almost 1,000 pounds off a car's weight currently taken up by conventional engine systems." Link to Original Source top

The mirror makes the hologram appear to be "floating" in air, while the Airborne Ultrasound Tactile Display shoots focused ultrasonic waves to create the feeling of a holographic ball or holographic rain falling on one's hand.
The Wii Remotes? They're used to track movement — just one of many non-gaming use scientist people are finding for Nintendo's hardware.

The actions of IGDA board member Tim Langdell since his election in March 2009 have raised questions regarding his suitability as our elected representative. As you no doubt know, the IGDA's mission is: To advance the careers and enhance the lives of game developers by connecting members with their peers, promoting professional development, and advocating on issues that affect the developer community.
Tim Langdell's company, Edge Games, has trademarked the word "edge" and they leverage this trademark against any media that contains this word--threatening legal action should their target not enter into a licensing arrangement with the studio. Such targets have included David Mamet's film The Edge, Marvel's comic book Edge, EA's Mirror's Edge, and Namco's Soul Edge, which was released as Soul Blade and later, Soulcalibur in the west as a direct result of Edge Games' actions. Most recently their actions have resulted in the removal of the indie game hit, Edge, from the iPhone app store.
Meanwhile, Edge Games has not been associated with the direct production of an original video game in the last fifteen years.
After his election to the IGDA board, in a lawsuit against Cybernet regarding Edge of Extinction, Tim Langdell presented himself to the court like this: "Dr. Tim Langdell is considered to be a pioneer in the field of computer gaming and is widely publicized on the Internet and has been engaged as a legal expert in the field of computer gamin." He adds "He presently serves on the Board of Directors of the International Game Developers Association, which is the largest game association worldwide". Many of us believe that this is a gross misrepresentation and feel that Tim Langdell is able to use his position on the board of the IGDA to work directly against the mission of the organization. As IGDA members with voting rights, it is our responsibility to elect a board that we can trust to represent us. But no election system is perfect and sometimes corrections need to be made.
We are asking that you take some time to consider this issue, do a little research online, make up your mind how you feel about it, and take action.
Under the IGDA bylaws, we are able to call for a special meeting of the membership to vote on the removal of Tim Langdell from the board of directors. In order to do this, we need 10% of the membership to request the board call the special meeting. We are hosting a petition to this effect here: http://www.surveymonkey.com/s.aspx?sm=68SOsjTK_2f9qJvOQ_2b2Zw7_2fA_3d_3d
Thank you for your consideration, Concerned Members of the IGDA
Renault-Nissan and Project Better Place recently announced a plan to make Israel oil-free by 2010. They are going to do this by building an electric car infrastructure — vehicles with swap-out-able batteries, and a system of 500,000 re-charging facilities across the country.
First, this group has a better chance than most to actually succeed. It's got the backing of a major auto manufacturer ready to build dedicated vehicles, local oil refining interests are financially invested, the project developers are smart as hell and have more money than God, and it's all facilitated by a government that sees the issue as a real national security issue. Plus, Israel is perfect for electric cars. I mean really-how far can you go, even if you wanted to?...." Link to Original Source top

The opening session of the conference, rather heartbreakingly, began with a slide saying "Just wait till next year!" The uncomfortable thought, which had begun to take shape the previous day during the tour of solar installations in Los Angeles, arrived in its final form: "After all this time, how is this something to celebrate?!"
This is what I came to find out about. Do people in the U.S. get it yet? As California is such a leader in environmental policy, if they understood the benefits of a [Renewable Energy Feed-in-Tarriff] system...they could accelerate solar power use massively." Link to Original Source
