Australian Team Working On Engines Without Piston Rings 368

Posted by Unknown Lamer from the more-power dept.
JabrTheHut writes "An Australian team is seeking funding for bringing an interesting idea to market: cylinder engines without piston rings. The idea is to use small grooves that create a pressure wave that acts as a seal for the piston, eliminating the piston ring and the associated friction. Engines would then run cooler, could be more energy efficient, and might even burn fuel more efficiently, at least according to the article. Mind you, they haven't even built a working prototype yet. If it works I'd love to fit this into an older car."

Researchers: Global Risk of Supervolcano Eruption Greater Than Previously Though 325

Posted by samzenpus from the big-boom dept.
rbrandis writes "The eruption of a 'supervolcano' hundreds of times more powerful than conventional volcanoes – with the potential to wipe out civilization as we know it – is more likely than previously thought, a study has found. An analysis of the molten rock within the dormant supervolcano beneath Yellowstone National Park in the United States has revealed that an eruption is possible without any external trigger, scientists said."

Congressman Accepts BitCoin For His US Senate Run 165

Posted by timothy from the so-giving-of-him dept.
SonicSpike writes "U.S. Representative Steve Stockman, a vocal opponent of Federal Reserve policy, told reporters that he wants to promote Bitcoin, whose most fervent evangelists tout as an alternative to fiat currency. To do so, he is now accepting Bitcoin for his Senate campaign against incumbent John Cornyn of Texas. The announcement was made last night at the launch event for the NYC Bitcoin Center, located just up the street from the New York Stock Exchange. Center founder Nick Spanos a real estate developer and Bitcoin enthusiast says the Center itself is still in something of a planning stage, existing more as a statement about Bitcoin itself, though he plans on hosting a hackathon later this month."

Coca-Cola Reserves a Massive Range of MAC Addresses 371

Posted by timothy from the maytag-and-starbucks-champing-at-bit dept.
An anonymous reader writes "GNU MacChanger's developer has found by chance that The Coca-Cola company got a range of MAC addresses allocated at the OUI, the IEEE Registration Authority in charge of managing the MAC addresses spectrum. What would Coca-Cola want around 16 million MAC addresses reserved? What are they planning to use them for? Could this part of a strategy around the Internet-of-things concept?"

US Customs Destroys Virtuoso's Flutes Because They Were "Agricultural Items" 894

Posted by samzenpus from the this-one-time-at-customs-camp dept.
McGruber writes "Flute virtuoso Boujemaa Razgui performed on a variety of flutes, each made by himself over years for specific types of ancient and modern performance. Razgui has performed with many U.S. ensembles and is a regular guest with the diverse and enterprising Boston Camerata. Last week, Razgui flew from Morocco to Boston, with stops in Madrid and New York. In New York, he says, a US Customs official opened his luggage and found the 13 flutelike instruments — 11 nays and two kawalas. Razgui says he had made all of the instruments using hard-to-find reeds. 'They said this is an agriculture item,' said Razgui, who was not present when his bag was opened. 'I fly with them in and out all the time and this is the first time there has been a problem. This is my life.' When his baggage arrived in Boston, the instruments were gone. He was instead given a number to call. 'They told me they were destroyed,' he says. 'Nobody talked to me. They said I have to write a letter to the Department of Agriculture in Washington, D.C. This is horrible. I don't know what to do. I've never written letters to people.'"

New Study Shows One-Third of Americans Don't Believe In Evolution 1010

Posted by Unknown Lamer from the vorlons-did-it dept.
Hugh Pickens DOT Com writes "Reuters reports that thirty-three percent of Americans reject the idea of evolution and believe that 'humans and other living things have existed in their present form since the beginning of time' rather than evolving gradually through a process of natural selection, as described by Charles Darwin more than 150 years ago. Although this percentage remained steady since 2009, the last time Pew asked the question, there was a growing partisan gap on whether humans evolved. The poll showed 43 percent of Republicans and 67 percent of Democrats say humans have evolved over time, compared with 54 percent and 64 percent respectively four years ago. 'The gap is coming from the Republicans, where fewer are now saying that humans have evolved over time,' says Cary Funk. Among religious groups, white evangelical Protestants topped the list of those rejecting evolution, with 64 percent of those polled saying they believe humans have existed in their present form since the beginning of time."
