Black Hole Emits a 1,000-Light-Year-Wide Gas Bubble 145

PhrostyMcByte writes "12 million light-years away, in the outer spiral of galaxy NGC 7793, a bubble of hot gas approximately 1,000 light-years in diameter can be found shooting out of a black hole — one of the most powerful jets of energy ever seen. (Abstract available at Nature.) The bubble has been growing for approximately 200,000 years, and is expanding at around 1,000,000 kilometers per hour."

Concrete That Purifies the Air 88

fergus07 writes "Although much of the focus of pollution from automobiles centers on carbon emissions, there are other airborne nasties spewing from the tailpipes of fossil fuel-powered vehicles. These include nitrogen oxides (NOx). In the form of nitrogen dioxide it reacts with chemicals produced by sunlight to form nitric acid – a major constituent of acid rain – and also reacts with sunlight, leading to the formation of ozone and smog. Everyone is exposed to small amounts of nitrogen oxides in ambient air, but exposure to higher amounts, in areas of heavy traffic for example, can damage respiratory airways. Testing has shown that surfacing roads with air purifying concrete could make a big contribution to local air purity by reducing the concentration of nitrogen oxides by 25 to 45 percent."

Things You Drink Can Be Used To Track You 202

sciencehabit writes with an intriguing story about the potential of figuring out where people have been by examining their hair: "That's because water molecules differ slightly in their isotope ratios depending on the minerals at their source. Researchers found that water samples from 33 cities across the United State could be reliably traced back to their origin based on their isotope ratios. And because the human body breaks down water's constituent atoms of hydrogen and oxygen to construct the proteins that make hair cells, those cells can preserve the record of a person's travels. Such information could help prosecutors place a suspect at the scene of a crime, or prove the innocence of the accused." Or frame someone by slipping them water from every country on the terrorist watchlist.

The "King of All Computer Mice" Finally Ships Screenshot-sm 207

An anonymous reader writes "The much-anticipated, much-mocked 18-button joystick mouse from WarMouse is now shipping. The press release features an impressive set of user quotes from game designer Chris Taylor, new SFWA president John Scalzi, and a doctor who runs a medical software company. Crazy or not, it's obviously more than just a gaming mouse."

New Estimates Say Earth's Oceans Smaller Than Once Believed 263

Velcroman1 writes with this snippet from Fox News: "Using lead weights and depth sounders, scientists have made surprisingly accurate estimates of the ocean's depths in the past. Now, with satellites and radar, researchers have pinned down a more accurate answer to that age-old query: How deep is the ocean? And how big? As long ago as 1888, John Murray dangled lead weights from a rope off a ship to calculate the ocean's volume — the product of area and mean ocean depth. Using satellite data, researchers from the Woods Hole Oceanographic Institute set out to more accurately answer that question — and found out that it's 320 million cubic miles. And despite miles-deep abysses like the Mariana Trench, the ocean's mean depth is just 2.29 miles, thanks to the varied and bumpy ocean floor."

Google Stops Ads For "Cougar" Sites 319

teh31337one writes "Google is refusing to advertise CougarLife, a dating site for mature women looking for younger men. However, they continue to accept sites for mature men seeking young women. According to the New York Times, CougarLife.com had been paying Google $100,000 a month since October. The Mountain View company has now cancelled the contract, saying that the dating site is 'nonfamily safe.'"

Submission + - Microsoft sees 60% jump in profit with Windows 7 (bbc.co.uk)

An anonymous reader writes: Microsoft has reported a 60% jump in profit, thanks largely to "exceptional demand" for Windows 7.

Net profit came in at $6.66bn (£4.13bn) for the three months to 31 December 2009, up from the $4.18bn it made in the same period a year earlier.

"We are thrilled by the consumer reception to Windows 7," said Kevin Turner, chief operating officer.

Submission + - Laser Fusion Passes Major Hurdle (bbc.co.uk)

chill writes: The National Ignition Facility at Lawrence Livermore National Laboratory has performed their first controlled fusion experiments using all 192 lasers. While still not ramped up to full power, the first experiments proved very fruitful. The lasers create a lot of plasma in the target container and it was worried that the plasma would interfere with the ability of the target to absorb enough energy to ignite. These experiments show that not only does enough energy make it through, the plasma can be manipulated to increase the uniformity of compression. Ramping up of power is due to start in May.

Dinosaur Feather Color Discovered 219

anzha writes "Do you remember being a kid and told we'd never know what colors the dinosaurs were? For at least some, that's no longer true. Scientists working in the UK and China have closely examined the fossils of multiple theropods and actually found the colors and patterns that were present in the fossilized proto-feathers. So far, the answer is orange, black and white in banded and other patterns. The work also thoroughly thrashes the idea that fossils might not be feathers, but collagen fibers instead. If this holds up, Birds Are Dinosaurs. Period. And colorful!"

Police Called Over 11-Year-Old's Science Project Screenshot-sm 687

garg0yle writes "Police in San Diego were called to investigate an 11-year-old's science project, consisting of 'a motion detector made out of an empty Gatorade bottle and some electronics,' after the vice-principal came to the conclusion that it was a bomb. Charges aren't being laid against the youth, but it's being recommended that he and his family 'get counseling.' Apparently, the student violated school policies — I'm assuming these are policies against having any kind of independent thought?"

Own Your Own Fighter Jet Screenshot-sm 222

gimmebeer writes "The Russian Sukhoi SU-27 has a top speed of Mach 1.8 (more than 1,300 mph) and has a thrust to weight ratio greater than 1 to 1. That means it can accelerate while climbing straight up. It was designed to fight against the best the US had to offer, and now it can be yours for the price of a mediocre used business jet."

Duke Nukem Forever Not Dead? (Yes, This Again) 195

kaychoro writes "There may be hope for Duke Nukem Forever (again). 'Jon St. John, better known as the voice of Duke Nukem, said some interesting words during a panel discussion at the Music and Games Festival (MAGFest) that took place January 1 – 4 in Alexandria, Virginia, according to Pixel Enemy. Answering a question from the crowd regarding DNF, St. John said: "... let me go ahead and tell you right now that I'm not allowed to talk about Duke Nukem Forever. No, no, don't be disappointed, read between the lines — why am I not allowed to talk about it?"'"
