An Animal That Lives Without Oxygen 166

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

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

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."

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

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

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."

In Michigan we have a lower offense level for driving while visibly impaired, for which you don't have to have .08 to be guilty. It's basically up to the cop to decide if you had too much to drink, which to my scientific side sounds pretty dumb. I want a hard number, I don't like the idea of I had one beer, and I don't know if it's illegal to drive or not, even though it has little to no effect.

Yeah, it does sound like it's difficult to lose weight once you get fat, so you are probably screwed now, I'm sorry. Some people just don't win the genetic lottery. People didn't used to be this fat, but they didn't gain the weight in the first place, it's not like it has suddenly become harder to lose weight. I suspect it's much easier to keep the weight off in the first place, and that's what I plan to do.

I check my weight fairly frequently, not that it has been out of the same 5 pound range for the last 3 years since I lost 5 pounds (not something I was trying to do) while traveling/living in South America for a 6 months. I think that may have come from climbing mountains. Not that you probably have time or the physical conditions to climb mountains, but if you do go up to fairly high altitude, maybe 12 thousand feet or higher, you will lose your appetite while you are there. When I was climbing mountains, I ate maybe 500-1000 calories in a day, and that was somewhat forced. Parents should monitor their children's weight too, it's no good letting a child get fat before they can take responsibility for themselves.

If you are always hungry when you diet anyway, you could try fasting for a week or 2, I've heard (though I've never done it myself for more than a day) that hunger goes away after 3-4 days as long as you aren't eating anything, though it comes back as soon as you do eat something.
