What's Hidden Under Greenland's Ice? 246

Posted by Zonk from the in-his-house-at-r'lyeh-dead-cthulhu-waits-dreaming dept.
Roland Piquepaille writes "Ice has covered Greenland for millions of years. So what's hidden under this ice cap? Mountains and valleys? Rivers and lakes? Of course, we might know it sooner than we would have liked if the ice covering Greenland continues to melt. But researchers from Ohio State University have decided that they wanted to know it next year and have developed a radar to reveal views of land beneath polar ice. Their first tests of this new radar, which helps them to catch 3-D images of the ground under the ice, took place in May 2006. The next images will be shot in April 2007. Here are some images of the new GISMO device and what it can do."

BLAST Telescope About To Launch From Antarctica 51

Posted by kdawson from the up-up-and-around dept.
mtruch writes "BLAST, the Balloon-borne Large Aperture Sub-millimeter Telescope, is about to be launched from McMurdo Station, Antarctica. BLAST is a 2700 kg telescope with a 2 meter primary mirror that hangs from a 1.1 million cubic meter balloon floating at an altitude of 38 km that will study the star formation history of the universe. It will float west at nearly constant latitude for about 14 days until it is (hopefully) located over McMurdo again and will be terminated and recovered. Real time position and flight track is available from the CSBF. Watch the launch live via a crappy webcam link. Three of the graduate students working on the project have photo blogs of much of the prep period, and specifically Don's blog should have launch photos soon (bandwidth to/from McMurdo is at a premium). BLAST made it on Slashdot in the past, when it launched from Sweden in June 2005, and indirectly with an interview with Prof. Barth Netterfield and George Staikos. Yes, the flight computers still run Slack, and yes, we still use kst for data viewing and analysis. There is a Discovery Science show about BLAST and high-altitude balloons, and a future documentary film being made as well."

DARPA Funds Remote Control Sharks 137

Posted by CmdrTaco from the sunday-morning-new-baby dept.
An anonymous reader writes "From Undersea Spies: Turning Sharks into Robotic Sentries "It seems like science fiction, but the U.S. military would like to use sharks as underwater spies. The folks at the Defense Advanced Research Projects Agency (DARPA), who dream up the future of weapons and military systems, envision squads of sharks prowling the oceans with sensors that could transmit evidence of explosives or other threats.""

Who Cares If Privacy Is Slipping Away? 393

Posted by kdawson from the going-going dept.
IAmTheDave writes, "This morning MSNBC's home page is topped by the opening story in a series, Privacy Under Attack, But Does Anybody Care? Privacy rights have been debated to death here on Slashdot, but this article attempts to understand people's ambivalence towards the decline of privacy. The article discusses how over 60 percent of Americans — while somewhat unable to quantify what exactly privacy is and what's being lost — feel a pessimism about privacy rights and their erosion. However, a meager 6-7% polled have actually taken any steps to help preserve their privacy. The article's call to action: '...everyone has secrets they don't want everyone else to know, and it's never too late to begin a discussion about how Americans' right to privacy can be protected.'"

New Robot Glides Through Intestines 96

Posted by Zonk from the i-am-proud-to-live-in-a-time-where-this-is-possible dept.
TechFreep writes to mention a NewScientist article about a new mucus-riding robot, intended for use in medical examinations of the intestinal tract. The snail-like bot, it is hoped, will be easier on the internal organs of patients than similar robots which use small leg-like structures. From the article: "Dodou is testing a polymer material that clings to proteins found in the mucus that lines the gut. She measured the polymer's sticky properties in the lab using sections of pig gut, and also examined the way the polymer's stickiness can be 'switched off' by spraying it with water. This could allow a robot to move in a manner similar to a snail, which alternately makes itself sticky and slippery by exerting pressure with its body."

Vista Startup Sound to be Mandatory? 865

Posted by CowboyNeal from the any-sound-you-want-as-long-as-it's-this-one dept.
Toreo asesino writes "There has been lots of debate in the past few days over Microsoft's plan to make the startup sound in Windows Vista something that can't be specifically silenced by changing the sound settings in the control panel. Users would be able to avoid hearing it by manually turning down the speaker volume, but then they would have to turn that volume back up to hear anything else."
