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.

In addition to car exhaust and road grime, travelers along Highway 150 in North Carolina can now enjoy the smell of a barbecue thanks to a new billboard. The work of ScentAir, which provides custom scents for businesses, the advertisement for a local grocer emits the smell of charcoal and black pepper over the highway. "Marketing director Murray Dameron said the beef scent was emitted by a high-powered fan at the bottom of the billboard that blows air over cartridges loaded with BBQ fragrance oil. 'It smells like grilled meat with a nice pepper rub on it,' he explained."

Ant notes a piece up on WBUR Boston addressing theories to explain the universal human experience that time seems to pass faster as you get older. Here's the 9-minute audio (MP3). Several explanations are tried out: that brains lay down more information for novel experiences; that the "clock" for nerve impulses in aging brains runs slower; and that each interval of time represents a diminishing fraction of life as we age.

Hugh Pickens writes "In the aftermath of Microsoft's recent decision to contribute 20,000 lines of device driver code to the Linux community, Christopher Smart of Linux Magazine talked to Linus Torvalds and asked if the code was something he would be happy to include, even though it's from Microsoft. 'Oh, I'm a big believer in "technology over politics." I don't care who it comes from, as long as there are solid reasons for the code, and as long as we don't have to worry about licensing etc. issues,' says Torvalds. 'I may make jokes about Microsoft at times, but at the same time, I think the Microsoft hatred is a disease. I believe in open development, and that very much involves not just making the source open, but also not shutting other people and companies out.' Smart asked Torvalds if Microsoft was contributing the code to benefit the Linux community or Microsoft. 'I agree that it's driven by selfish reasons, but that's how all open source code gets written! We all "scratch our own itches." It's why I started Linux, it's why I started git, and it's why I am still involved. It's the reason for everybody to end up in open source, to some degree,' says Torvalds. 'So complaining about the fact that Microsoft picked a selfish area to work on is just silly. Of course they picked an area that helps them. That's the point of open source — the ability to make the code better for your particular needs, whoever the "your" in question happens to be.'"

zootropole alerts us to a press release issued today by Lawrence Livermore National Laboratory, announcing the production of 'billions of particles of anti-matter.' "Take a gold sample the size of the head of a push pin, shoot a laser through it, and suddenly more than 100 billion particles of anti-matter appear. The anti-matter, also known as positrons, shoots out of the target in a cone-shaped plasma 'jet.' This new ability to create a large number of positrons in a small laboratory opens the door to several fresh avenues of anti-matter research, including an understanding of the physics underlying various astrophysical phenomena such as black holes and gamma ray bursts." The press release doesn't characterize the laser used in this experiment, but it may have been this one.

Dan writes to mention a post at the Aeropause site. Author Richard was recently given the rare opportunity to interview a cheater, shining a light into the dark recesses of a conflicted mind. The article explores why the cheater cheats, and the great excuses they use to be able to look themselves in the mirror. From the article: "Aeropause: What made you decide to mod your Xbox to gain an unfair advantage in games like Halo 2? Schmuck5000: Modding is not an unfair advantage. There is just as much chance that there will be a modder on the other team. I am there to even things out. Halo 2 is beginning to get old, us modders are just making it more funner."

An anonymous reader writes "Player gets banned for playing World of Warcraft under WINE and using a Logitech Gaming keyboard. "I am an experienced network engineer for an ISP and I am often running World of Warcraft on Linux through the use of WINE..."" Although the e-mails exchanged are unclear my guess is that the programmable keyboard was more the problem then WINE. Not that you'd ever know that given that Blizzard communicates with their users seemingly almost exclusively with form letters.
