An Animal That Lives Without Oxygen 166

Posted by timothy from the besides-me dept.
Julie188 writes "Scientists have found the first multicellular animals that apparently live entirely without oxygen. The creatures reside deep in one of the harshest environments on earth: the Mediterranean Ocean's L'Atalante basin, which contains salt brine so dense that it doesn't mix with the oxygen-containing waters above."

Son Sues Mother Over Facebook Posts 428

Posted by samzenpus from the check-your-family-status dept.
Most kids hate having their parents join in on a discussion on Facebook, but one 16-year-old in Arkansas hates it so much he has filed suit against his mother, charging her with harassment. From the article: "An Arkadelphia mother is charged with harassment for making entries on her son's Facebook page. Denise New's 16-year-old son filed charges against her last month and requested a no-contact order after he claims she posted slanderous entries about him on the social networking site. New says she was just trying to monitor what he was posting." Seems like he could just unfriend her.

Ok, I looked up their website rather than the article, and they have had the thing up to 43 mph, which is faster than I can go unless I draft a car, and they say it could go faster if it were geared differently (at a lower MPG of course).

I did actually calculate out the CO2 output equivalency of riding a bike is actually about 90 MPG for the average American on the average diet. I doubt that much of what they do to get this kind of mileage can ever have practical use though. I'd be more interested in a practical vehicle that got 100 mpg.

Plus I think I'm a little annoyed that this article made Slashdot because vehicles and numbers like this have been around for years, and I find nothing particularly impressive about this particular one.

Outlook 2010 Bug Creates Monster Email Files 126

Posted by timothy from the rodents-of-unusual-size dept.
Julie188 writes with this snippet from Network World "Office 2010 is still in beta and a patch is already out. Microsoft is trying to fix a bug in the email program Outlook 2010 Beta that creates unusually large e-mail files that take up too much space. The Outlook product team has offered a bug fix for both 32-bit and 64-bit systems that fixes the problem going forward, although previous emails will remain super-sized. This could be a problem for email programs that limit message sizes, such as Gmail or BlackBerry."

Measuring the Speed of Light With Valentine's Day Chocolate 126

Posted by samzenpus from the speed-of-the-sound-of-loneliness dept.
Cytotoxic writes "What to do with all of those leftover Valentine's Day chocolates? — a common problem for the Slashdot crowd. The folks over at Wired magazine have an answer for you in a nice article showing how to measure the speed of light with a microwave and some chocolate. A simple yet surprisingly accurate method that can be used to introduce the scientific method to children and others in need of a scientific education."

Using EMP To Punch Holes In Steel 165

Posted by timothy from the you'll-need-some-big-batteries dept.
angrytuna writes "The Economist is running a story about a group of researchers at the Fraunhofer Institute for Machine Tools and Forming Technology in Chemnitz, Germany, who've found a way to use an EMP device to shape and punch holes through steel. The process enjoys advantages over both lasers, which take more time to bore the hole (0.2 vs. 1.4 seconds), and by metal presses, which can leave burrs that must be removed by hand."

NASA To Cryogenically Freeze Satellite Mirrors 47

Posted by Soulskill from the ain't-it-cool dept.
coondoggie writes "NASA said it will soon move some of the larger (46 lb) mirror segments of its future James Webb Space Telescope into a cryogenic test facility that will freeze the mirrors to -414 degrees Fahrenheit (~25 K). Specifically, NASA will freeze six of the 18 Webb telescope mirror segments at the X-ray and Cryogenic Facility, or XRCF, at NASA's Marshall Space Flight Center in Huntsville, Alabama, in a test to ensure the critical mirrors can withstand the extreme space environments. All 18 segments will eventually be tested at the site. The test chamber takes approximately five days to cool a mirror segment to cryogenic temperatures."

Aussie Scientists Find Coconut-Carrying Octopus 205

Posted by timothy from the concealed-carry-in-australian-waters dept.
An anonymous reader writes with this excerpt from an AP report: "Australian scientists have discovered an octopus in Indonesia that collects coconut shells for shelter — unusually sophisticated behavior that the researchers believe is the first evidence of tool use in an invertebrate animal. The scientists filmed the veined octopus, Amphioctopus marginatus, selecting halved coconut shells from the sea floor, emptying them out, carrying them under their bodies up to 65 feet (20 meters), and assembling two shells together to make a spherical hiding spot. ... 'I was gobsmacked,' said Finn, a research biologist at the museum who specializes in cephalopods. 'I mean, I've seen a lot of octopuses hiding in shells, but I've never seen one that grabs it up and jogs across the sea floor. I was trying hard not to laugh.'"

Zombie Pigs First, Hibernating Soldiers Next 193

Posted by samzenpus from the fattening-up-on-brains dept.
ColdWetDog writes "Wired is running a story on DARPA's effort to stave off battlefield casualties by turning injured soldiers into zombies by injecting them with a cocktail of one chemical or another (details to be announced). From the article, 'Dr. Fossum predicts that each soldier will carry a syringe into combat zones or remote areas, and medic teams will be equipped with several. A single injection will minimize metabolic needs, de-animating injured troops by shutting down brain and heart function. Once treatment can be carried out, they'll be "re-animated" and — hopefully — as good as new.' If it doesn't pan out we can at least get zombie bacon and spam."

Engineered Bacteria Glows To Reveal Land Mines 248

Posted by kdawson from the lamp-unto-your-feet dept.
MikeChino writes "Sifting through minefields to remove hidden threats is a dangerous, tedious, and expensive process. Scientists at the University of Edinburgh recently announced that they have engineered a strain of bacteria that glows green in the presence of explosives, making mine detection a snap. The new strain of bacteria can be sprayed onto local affected areas or air-dropped over entire fields of mines. Within a few hours the bacteria strain begins to glow wherever traces of explosive chemicals are present."

Future of NASA's Manned Spaceflight Looks Bleak 452

Posted by kdawson from the send-out-the-machines dept.
coondoggie writes "Things don't look good for NASA when the report outlining its future begins: 'The US human spaceflight program appears to be on an unsustainable trajectory. [NASA] is perpetuating the perilous practice of pursuing goals that do not match allocated resources. Space operations are among the most complex and unforgiving pursuits ever undertaken by humans. It really is rocket science. Space operations become all the more difficult when means do not match aspirations.' Today the Augustine Commission handed to the White House the Review of US Human Space Flight Plans Committee summary report, after months of expert review and testimony. Many observers expected a bleak report, but ultimately the future of US manned space flight will hinge on how the report's conclusions are interpreted. Keep in mind too that NASA has spent almost $8 billion of a planned $40 billion to develop systems for a return to the Moon."
