First Measurement of Magnetic Field In Earth's Core 34

An anonymous reader writes "A University of California, Berkeley, geophysicist has made the first-ever measurement of the strength of the magnetic field inside Earth's core, 1,800 miles underground. The magnetic field strength is 25 Gauss, or 50 times stronger than the magnetic field at the surface that makes compass needles align north-south. Though this number is in the middle of the range geophysicists predict, it puts constraints on the identity of the heat sources in the core that keep the internal dynamo running to maintain this magnetic field."

Download Firefox, Feed a Red Panda Screenshot-sm 90

KenW writes "Mozilla has launched a new marketing campaign to promote Firefox: adopting red pandas and putting them on live webcams. The company wants to underline the fact that the red panda is the mascot for its open source browser via a new section on its site called Firefox Live. It's clear that Mozilla is trying to think of new ways to promote its browser ahead of the launch of Firefox 4. The company has been struggling recently as Firefox steadily loses share to Google Chrome."

Background Noise Affects Taste of Foods 79

gollum123 writes "The level of background noise affects both the intensity of flavour and the perceived crunchiness of foods, researchers have found. Blindfolded diners assessed the sweetness, saltiness, and crunchiness, as well as overall flavour, of foods as they were played white noise. While louder noise reduced the reported sweetness or saltiness, it increased the measure of crunch. It may go some way to explaining why airline food is notoriously bland — a phenomenon that drives airline catering companies to season their foods heavily. In a comparatively small study, 48 participants were fed sweet foods such as biscuits or salty ones such as crisps, while listening to silence or noise through headphones. Also in the group's findings there is the suggestion that the overall satisfaction with the food aligned with the degree to which diners liked what they were hearing — a finding the researchers are pursuing in further experiments."

Morphing Metals 121

aarondubrow writes "Imagine a metal that 'remembers' its original, cold-forged shape, and can return to that shape when exposed to heat or a magnetic pulse. Like magic out of a Harry Potter novel, such a metal could contract on command, or swing back and forth like a pendulum. Believe it or not, such metals already exist. First discovered in 1931, they belong to a class of materials called 'shape memory alloys (SMA),' whose unique atomic make-up allows them to return to their initial form, or alternate between forms through a phase change."

The Best Video Games On Awful Systems 272

Buffalo55 writes "For the most part, classic games manage to reappear on different systems. Just look at Nintendo. The publisher has done an excellent job bringing NES, SNES, Genesis and even old school Neo Geo titles to the Wii's Virtual Console, while Microsoft's Game Room brings the best of Atari's 2600 into the living room. Of course, not every console was a success. The '90s, in particular, saw quite a few flops from companies like Panasonic, Sega and Atari. Just because a system is a failure, though, doesn't mean all of its games suck. On the contrary, most of these machines have a few gems that fell between the cracks once the console croaked." What overlooked game on a failed platform would you like to see revived?

Radioactive Boar On the Rise In Germany Screenshot-sm 165

Germans who go out in the woods today are sure of a big surprise, radioactive boars. A portion of the wild boar population in Germany was irradiated after the Chernobyl nuclear meltdown, and the boars are thriving. In the last two years government payments to compensate hunters for radioactive boar have quadrupled. From the article: "According to the Environment Ministry in Berlin, almost €425,000 ($555,000) was paid out to hunters in 2009 in compensation for wild boar meat that was too contaminated by radiation to be sold for consumption. That total is more than four times higher than compensation payments made in 2007." I think the Germans are overlooking just how much money there is to be made from regenerating bacon.

Indian Police Using Facebook to Catch Scofflaw Drivers Screenshot-sm 130

New Delhi police have a new weapon in the battle against bad drivers, Facebook. Two months ago the police created a Facebook page that allowed people to inform on others breaking traffic laws, and upload pictures of the violations. The page has more than 17,000 fans, and 3,000 pictures currently. From the article: "The online rap sheet was impressive. There are photos of people on motorcycles without helmets, cars stopped in crosswalks, drivers on cellphones, drivers in the middle of illegal turns and improperly parked vehicles. Using the pictures, the Delhi Traffic Police have issued 665 tickets, using the license plate numbers shown in the photos to track vehicle owners, said the city’s joint commissioner of traffic, Satyendra Garg."

New Mars Rover Rolls For the First Time 100

wooferhound writes "Like proud parents savoring their baby's very first steps, mission team members gathered in a gallery above a clean room at NASA's Jet Propulsion Laboratory to watch the Mars Curiosity rover roll for the first time. Engineers and technicians wore bunny suits while guiding Curiosity through its first steps, or more precisely, its first roll on the clean room floor. The rover moved forward and backward about 1 meter (3.3 feet). Mars Science Laboratory (aka Curiosity) is scheduled to launch in fall 2011 and land on the Red Planet in August 2012. Curiosity is the largest rover ever sent to Mars. It will carry 10 instruments that will help search an intriguing region of the Red Planet for two things: environments where life might have existed, and the capacity of those environments to preserve evidence of past life."

Believing You Are Very Good Or Evil Boosts Your Physical Capabilities Screenshot-sm 192

Research by Kurt Gray, a doctoral student in psychology at Harvard, shows that a person's capacity for willpower and physical endurance increases if they perceive themselves as good or evil. "Evil" acts in particular give a person a large boost in physical strength. From the article: “'People perceive those who do good and evil to have more efficacy, more willpower, and less sensitivity to discomfort,' Gray said. 'By perceiving themselves as good or evil, people embody these perceptions, actually becoming more capable of physical endurance.' Gray’s findings run counter to the notion that only those blessed with heightened willpower or self-control are capable of heroism, suggesting instead that simply attempting heroic deeds can confer personal power."

Submission + - What's causing that hole in the clouds? (sciencemag.org)

cremeglace writes: Researchers have found the mechanism for why airplanes cause rain when they take off or descend through altocumulus clouds. The clouds, which range in altitude from about 1 to 6 kilometers, have been known to develop gaping holes near airports, which usually brought immediate, localized precipitation. ScienceNOW has the full explanation and a picture.

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."

Researchers Pooh-Pooh Algae-Based Biofuel 238

Julie188 writes "Researchers from the University of Virginia have found that current algae biofuel production methods consume more energy, have higher greenhouse gas emissions and use more water than other biofuel sources, such as switchgrass, canola and corn. The researchers suggest these problems can be overcome by situating algae production ponds behind wastewater treatment facilities to capture phosphorous and nitrogen — essential algae nutrients that otherwise need to come from petroleum."

Facebook Master Password Was "Chuck Norris" Screenshot-sm 319

I Don't Believe in Imaginary Property writes "A Facebook employee has given a tell-all interview with some very interesting things about Facebook's internals. Especially interesting are all the things relating to Facebook privacy. Basically, you don't have any. Nearly everything you've ever done on the site is recorded into a database. While they fire employees for snooping, more than a few have done it. There's an internal system to let them log into anyone's profile, though they have to be able to defend their reason for doing so. And they used to have a master password that could log into any Facebook profile: 'Chuck Norris.' Bruce Schneier might be jealous of that one."
