Hints of Life Found On Saturn's Moon Titan 227

Calopteryx writes "New Scientist reports that in 2005, researchers predicted two potential signatures of life on Titan. Now, thanks to research done with the help of the Cassini spacecraft, both have been seen, although non-biological chemical reactions could also be behind the observations. NASA's writeup has further details: 'One key finding comes from a paper online now in the journal Icarus [abstract] that shows hydrogen molecules flowing down through Titan's atmosphere and disappearing at the surface. Another paper online now in the Journal of Geophysical Research maps hydrocarbons on the Titan surface and finds a lack of acetylene. This lack of acetylene is important because that chemical would likely be the best energy source for a methane-based life on Titan, said Chris McKay, an astrobiologist at NASA Ames Research Center, Moffett Field, Calif., who proposed a set of conditions necessary for this kind of methane-based life on Titan in 2005. One interpretation of the acetylene data is that the hydrocarbon is being consumed as food. But McKay said the flow of hydrogen is even more critical because all of their proposed mechanisms involved the consumption of hydrogen.'"

Blizzard vs. Glider Battle Resumes Next Week 384

trawg writes "You paid for it, you have the DVD in your drive and the box on the floor next to your desk, but do you own the game? That's the question the 9th Circuit Court of Appeals will rule on next week in the case between Blizzard, publisher of World of Warcraft, and MDY, publisher of the Glider bot. The Glider bot plays World of Warcraft for you, but Blizzard frowns on this, saying it voids the license agreement — you don't own the game, you only have a license to use it, and bots like Glider invalidate the license. The EFF has a good summary of the case as well. The case is due to be resumed on Monday."

Guess My Speed and Give Me a Ticket, In Ohio 636

quall writes "The Ohio Supreme Court has ruled that police may estimate your car's speed and issue a ticket if they believe you were speeding. The hearing threw out a radar gun as evidence because the officer was not qualified to use it, but apparently his guess was good enough. If you make your way into Ohio, I suggest driving 5mph under the speed limit because this leaves little room to dispute your ticket in court. The only chance you have is if the issuing officer decides to skip your hearing." I wonder whether the court would also accept a driver's own GPS log as exculpatory evidence.

Mars Rover Opportunity Sets Longevity Record 61

s31523 writes "The Mars rover Opportunity has beaten the original record of six years and 116 days operating on the surface of Mars, originally set by the Viking 1 Lander. While the Spirit rover has been on the surface longer than the Opportunity by three weeks, it has been out of communication since March 22. If Spirit comes back online, it will attain the new Martian surface longevity record. This feat, right on the heels of another longevity feat (Voyager 2 and twin on the verge of entering interstellar space and still kicking) is healing some of NASA's past black eyes. It is quite remarkable given original spec of 90 days for the mission. With the passing of the solstice, warmer temperatures and more sun will likely mean the rover will continue on."

A Playable PAC-MAN On Google Doodle 286

Kilrah_il and several other readers made sure we noted Google's tribute to PAC-MAN on its 30th anniversary — a playable game implemented in JavaScript. "'To play the game, go to google.com during the next 48 hours (because it's too cool to keep for just one day) and either press the "Insert Coin" button or just wait for a few seconds.' There is also an Easter egg for those who want to recall one of the first multi-player games, but you'll have to RTFA to find it." This doodle may overshadow the Official PAC-MAN 30th Anniversary Destination.

Are Googlers Too Smart For Their Own Good? 307

theodp writes "If you're a mere mortal, don't be surprised if your first reaction to Google Storage for Developers is 'WTF?!' Offering the kind of 'user-friendly' API one might expect from a bunch of computer science Ph.D.s, Google Storage even manages to overcomplicate the simple act of copying files. Which raises the question: Are Googlers with 'world-class programming skills' capable of producing straightforward, simple-to-use programming interfaces for ordinary humans?"

The Mystery of the Missing Methane 98

Hugh Pickens writes "Astrobiology Magazine reports that NASA's Spitzer Space Telescope has discovered something odd about GJ 436b, a planet about the size of Neptune located 33 light-years away, circling the star Gliese 436. The mystery? GJ 436b lacks methane, an ingredient common to many of the planets in our solar system. Methane is present on our life-bearing planet, manufactured primarily by microbes living in cows, and all of the giant planets in our solar system have methane too, despite their lack of cows. Spitzer was able to detect the faint glow of GJ 436b by watching it slip behind its star, an event called a secondary eclipse. As the planet disappears, the total light observed from the star system drops, and the diference is then measured to find the brightness of the planet at various wavelengths. Eventually, a larger space telescope could use the same kind of technique to search smaller, Earth-like worlds for methane and other chemical signs of life, such as water, oxygen and carbon dioxide. Adam Showman, a planetary scientist at the University of Arizona, says the 'provocative result' raises questions about the evolution of this planet, as well as the possibility that its atmosphere might represent an entirely new class of atmospheres that has never been explored."

Comment Gave up on Ubuntu (Score 1) 936

I tried for four days to get Ubuntu working on an old P3 1ghz I had lying around. I have a Radeon 9700 graphics card and couldn't get the drivers to install. I went to ATI's site got the drivers and installed them. I ended up having to reinstall Unbuntu because it booted up saying there was something wrong with the drivers and I could only run in low graphics mode. I then tried Envyng, it told me that one ATI driver was compatible and 3 Nvidia drivers were compatible?? I chose the ATI one and I got the same error when I rebooted. It's to damn slow with out the proper drivers. So I give up, I'm going back to XP.

Powering Restaurants WIth Deep Fried Fuel 148

Mike writes "Here's a brilliant idea for biofuels: rather than filtering used fry oil for use in vehicles, why not simplify matters and use it to heat and power the restaurant itself? The VegaWatt turns used vegetable oil into clean heat and energy for restaurants, eliminating the dirty and costly mess of oil disposal while producing 10-25% of the electricity needed to run a small restaurant. It also produces fuel free of chemicals or fossil fuels, unlike standard biodiesel."

1/3 of Amphibians Dying Out 467

Death Metal sends in a Scientific American article reporting that 2,000 of 6,000 amphibian species are endangered worldwide. A combination of environmental assaults, including global warming, seems to be responsible. "... national parks and other areas protected from pollution and development are providing no refuge. The frogs and salamanders of Yellowstone National Park have been declining since the 1980s, according to a Stanford University study, as global warming dries out seasonal ponds, leaving dried salamander corpses in their wake. Since the 1970s, nearly 75 percent of the frogs and other amphibians of La Selva Biological Station in Braulio Carrillo National Park in the Caribbean lowlands of Costa Rica have died, perhaps due to global warming. But the really bad news is that amphibians may be just the first sign of other species in trouble. Biologists at the University of California, San Diego, have shown that amphibians are the first to respond to environmental changes, thanks to their sensitivity to both air and water. What goes for amphibians may soon be true of other classes of animal, including mammals."
