Submission + - Europa Discovery Increases Odds of Life On Jovian Moon. (dailygalaxy.com)

tetrahedrassface writes: "Observations of spectral emissions from the surface of Europa using state of the art ground based telescopes here on Earth have lent data that indicate the surface of the Jovian moon is not merely ice that is not dynamically linked with the vast ocean below. The observations carried out by Caltech's Mike Brown, and JPL's Kevin Hand show that water is making it from the ocean below all the way up to the surface of the moon. In their study they noticed a dip in the emission bands around lower latitudes of the moon, and quickly honed in on what they were seeing. The mineral of interest is epsomite, a magnesium sulfate compound that can only come from the ocean below. From the article: 'Magnesium should not be on the surface of Europa unless it's coming from the ocean," Brown says. "So that means ocean water gets onto the surface, and stuff on the surface presumably gets into the ocean water.

Not only does this mean the ocean and surface are dynamically interacting but it also means that there may be more energy in the ocean than previously thought. Another finding is that the ocean below the icy surface of Europa is basically very similar to an ocean on Earth, giving the neglected and premier solar body for life past Earth another compelling reason for being explored."

Submission + - GPL Kerfuffle Kills Xbian for RaspberryPi (raspbmc.com) 1

tetrahedrassface writes: Rasbmc developer Sam Nazarko is reporting that Xbian had violated the GPL and stolen his installer code without providing attribution and not releasing their source. His breakdown of events is interesting, and currently the Xbian project has been taken offline with several tweets saying Xbian development is terminated.

Submission + - Chattanooga's EPB Doubles Down On Fiber Speeds. (timesfreepress.com)

tetrahedrassface writes: The first city in the U.S. to offer a screaming fast fiber network has now announced customers will get a free 60% boost in speed. If you had the 30 MB/sec service you now will get 50. Mid-range customers get a doubling for free, while the high end consumers of fiber get an average 250% boost. The fiber network recently passed 40,000 members and judging from a test of my business, we are currently over 300 MB/sec. It's awesome!

Submission + - Tennessee Crater Inches Toward Recognition. (98.68.146.117) 1

tetrahedrassface writes: "Slashdot carried the story of an-as-yet unverified impact crater in Tennessee a couple of years ago. After a few weeks of fairly hardcore sample taking, digging, obtaining some good images and manipulating them, I'm proud to report the first batch of evidence in favor of it being an impact site. The primary smoking gun is the presentation of an astrobleme , obtained from High Resolution Ornithographic Images taken in 2008. Also of note, are the melted/deformed rocks, magnetic crater dust, and the fitment of the crater rim to a circle. A rented plane and a bunch of photographs today and it's pretty obvious that it's a crater folks! Cheers!"

Submission + - NASA Successfully Test Fires J-2X Engine. (universetoday.com)

tetrahedrassface writes: "NASA successfully test fired the J-2X engine today for 500 seconds at Stennis Space Center. The J2-X is derived from the J2 engine from the Apollo Era, and will power the upper stage of the SLS. From the article: 'We have 500 seconds of good data, and the first look is that everything went great. The J-2X engine team and the SLS program as a whole are extremely happy that we accomplished a good, safe and successful test today,” said Mike Kynard, Space Launch System Engines Element Manager at NASA’s Marshall Space Flight Center in Huntsville, Ala. “This engine test firing gives us critical data to move forward in the engine’s development.'"

Submission + - Guitar Makers and Owners Under The Gun. (wsj.com)

tetrahedrassface writes: According to the Wall Street Journal, Federal agents again raided guitar maker Gibson this past week seizing several pallets of wood and computer documents. At heart of the issue is the wood that is being used in guitars and whether or not it comes from sustainable sources. The company insists it is being harassed and made to 'cry uncle' to the governments enforcement laws. While, as the article notes, wonderful woods like Madagascar Ebony, Brazilian Rosewood and other fret and tone woods are protected in order to prevent the equivalent of 'blood diamond like trade' in sought after tone woods, the ramafications now extend to guitar sowners. Owners and players are next in sights of this enforcement. If you play a vintage guitar, or a hand built guitar made of old stock woods that were legally obtained years ago, but only recently crafted into an ax, you best not fly with it. John Thomas, a law professor at Quinnipiac University and a blues and ragtime guitarist, says "there's a lot of anxiety, and it's well justified." Once upon a time, he would have taken one of his vintage guitars on his travels. Now, "I don't go out of the country with a wooden guitar." That's right. Recent revisions to various laws and the Lacey Act mean if you carry your guitar across the border and don't have your paperwork and certification in hand, they will seize the guitar and fine you 250.00. So if your planning that dream vacation to France and want to play your acoustic in the air of France (or anywhere else) be forewarned. They are gunning for you.

Submission + - Man Intends To Live On Beer Alone For Lent

tetrahedrassface writes: An Iowanian is living on nothing but beer for the 46 days of Lent. J.Wilson, a blogger, and editor of the weekly Adams County Free Press modeled this Lent exercise on 17'th century German Monks who practiced liquid fasts. Using a custom made grog that has high caloric values is key as Wilson says because ordinary light beer just doesn't have enough nutritional value. He has already lost 11 pounds while following his weekday four a day and weekend 5 a day beer scheme.

Submission + - Our Lazy Solar Dynamo: Hello Dalton Minimum? (wildwildweather.com)

tetrahedrassface writes: Solar maximum is supposed to be occurring, and everything from satellite communications, to your toaster, or radio could be affected. The only problem is that this just isn't happening, and NASA continues to revise down the original prediction. In fact the new prediction for Solar Cycle 24 is a lot smaller and now is pegged at almost 40% of what was predicted. Recently, two scientists at the National Solar Observatory have followed the lead of a prominent Russian scientist, who forecast a dearth of sunspots, and subsequent cooling of Earth for the next several cycles almost five years ago. With Britain currently experiencing the coldest winter in over 300 years, and no new sunspots for the last week, are we heading for a Dalton Minimum, or worse still, yet another Maunder?

Submission + - DDOS Attack on Wikileaks Increasing. (wikileaks.info)

tetrahedrassface writes: According to the twitter feed for wikileaks, the attack on the controversial site is increasing and is now at 10 Gigabits per second. In light of the recent release of highly sensitive documents and calls by many lawmakers around the world to swiftly find, extradite, and try suspected rapist Julius Assange for breaches of national security, one nation, Ecuador, has offered asylum.

Submission + - The Story Of My As Yet Unverified Impact Crater. 3

tetrahedrassface writes: When I was very young my dad took me on a trip to his parents farm. He wanted to show me 'The Crater'. We walked a long way through second generation hardwoods and finally stood on the rim of a hole that has no equal in this area. As I grew up I became more interested in 'The Crater", and would always tell friends about it. It is roughly 1,200 feet across, and 120 feet deep, and has a strange vibe about it. When you walk up to it, you feel like something really big happened here. Either the mother of all caves is down there, or a large object smashed into this place a long, long time ago. I bought aerial photo's when I was twelve and later send images from GIS to a geologist at a local university and he pretty much laughed me out of his office, saying that it was a sinkhole. He did wish me luck however. It may be sinkhole. Who knows?

Last week I borrowed a metal detector and went poking around, and have found the strangest shrapnel pieces I have ever seen. They are composed of a metal that reacts strongly to acids. The largest piece so far reacted with tap water and dishwashing detergent. My second trip today yielded lots of strange new pieces of metal, and hopefully one day the truth either way will be known. Backyard science is so much fun and who knows, ff it is indeed a cave maybe Cerberus resides there.

Submission + - ATM's That Dispense Gold Bars Coming To America. (cnbc.com) 1

tetrahedrassface writes: As the U.S. economic woes continue unabated, a German company is bringing gold bearing ATM'S to bear on Mainstreet America. The machines accept credit cards, and will dispense 1 gram, 5 gram, 10 gram and 1 ounce units, as well as various gold coins. The company hopes to install 35 bullion machines in the United States this year, hopefully have several hundred up and running by next year. The machines will be decorated like giant gold ingots and be over two meters tall. Physical gold has both pros and cons, but mainly from a safety standpoint would it be safe to have a couple of ounces in your pocket while walking around the mall? The giant gold dispensing ATM's will monitor the market conditions for gold every 10 minutes in order to reflect spot price changes as they occur.

Submission + - It's Official: Our Children Are Potty Mouths. (montrealgazette.com) 4

tetrahedrassface writes: When the Sociolinguistics Symposium met earlier this month swearing scholar Timothy Jay revealed that an increase in child swearing is directly related to an increase in adult swearing. It seems that vulgarity is increasing as pop culture continues to popularize vulgarities. The blame lies with media, public figures, politicians, but mostly ourselves. From the article: 'Children as young as two are now dropping f-bombs, with researchers reporting that more kids are using profanity — and at earlier ages — than has been recorded in at least three decades.'

Submission + - Falcon 9: High Stakes (floridatoday.com)

happylunarnewyear writes: "The first new rocket to be launched from the Cape since 2002 is assembled and upright on Launch Complex 40. Falcon 9 will undergo fueling testing and live firing tests before the launch occurs as soon as next month. The stakes couldn't be higher either. The much politicized proposal for a change in direction for NASA which includes scrapping the Constellation program in toto in favor of privatization and a new heavy lift vehicle, veritably rides on this rocket. If the launch goes well the plan for increased reliance on privatized cargo missions. and eventually privatized manned missions will soar with it. However if something goes wrong, those plans will come crashing to Earth along with Falcon 9. Given the stakes this launch is one of the most important in recent history. From the article, 'President Obama's proposal to shift transport of U.S. astronauts to the space station from government launchers to privatized ones could suffer politically if there's a high-profile problem with the first mission of the Falcon 9, by far the most talked about newcomer vying for the opportunity.'"
Robotics

Submission + - London Robotic Fire Brigade: Tremendous Results.

dustpan writes: The BBC has a story up about a quartet of robotic fire fighters that the London Fire Brigade is testing and with which have been achieving 'tremendous results'. The robots were developed by QinetiQ, which is a defence contractor. The London Fire Brigade has been testing the units since last year and the machines are primarily used in fires involving acetylene canisters. The group commander for hazardous materials and environmental protection with the LFB says that the robots have cut the time to resolve these potential hazards from 24 hours to 3. From the article: 'Three years ago we were shutting down parts of London for over 24 hours every other week. Now it doesn't even make the news.'

Submission + - Star Wars Tech: True Green Laser Developed.

dusty writes: "Remember those green lasers from Star Wars? Turns out that faking green lasers has been easy for years , but making true green laser diodes has been the stuff of science fiction. Until recently that is. Now researchers from Japan have created the world's first true green laser diode. Until now only red and blue laser diodes were available and now with the addition of green new TV's and projectors that are more efficient can be produced. And if you were wondering how green lasers pointers are already produced, it is a hack that involved doubling the frequency of an infrared laser. The new true green laser diodes have much higher efficiency than the current 6% leading many to expect big time laser display breakthroughs in the near future. Ars Technica has a well written article on this breakthrough, and although the current lasers are no where near the power of the Death Star or Luke's lightsaber, seems anything can happen given enough research and time."
