A study has found that everybody has a unique body odor, like their fingerprints, that could be used as an unique identifier. The study showed that a persons unique odor stayed the same even if they varied their diet with strong smelling foods such as garlic and spices. "These findings indicate that biologically-based odorprints, like fingerprints, could be a reliable way to identify individuals," said Monell chemist Jae Kwak. I would have thought that hundreds of years of dogs tracking people would have proved this, but it's nice to know that science has figured it out officially now.

NathanBFH writes "Many of the questions that make it to the Ask Slashdot pages come from young and aspiring programmers wanting to know the role math and education play in the profession, or what makes certain programmers so much more productive than others, or what the future of the craft will look like. One young programmer by the name of Jarosaw "sztywny" Rzeszótko decided to ask these types of questions (and more) to the programmers he admired the most who also, it turns out, happen to be some of the most influential computer scientists and programmers of the last several decades. The result? Most of them happily responded. The results include the following: Linus Torvalds (Linux), Bjarne Stroustrup (C++), James Gosling (Java), Tim Bray (XML, Atom), Guido Van Rossum (Python), Dave Thomas (Pragmatic Programmer), David Heinemeier Hansson (Rails Framework), and Googlers Steve Yegge and Peter Norvig."

Google Checkout Launched

Roy van Rijn informs us that Google's new online payment system is now online. "Under the name Checkout, the venture offers an incorporated manner to search, advertise and pay. If you buy something on Checkout, 2% and $0.20 go to Google. Paypal, the biggest competitor uses 1,9% and $0,30. Analysts compare Google/Paypal to for example Visa/Mastercard living peacefully together, while others predict the end of Paypal." W3K adds "You can use your Google account to store an unlimited number of credit cards and addresses. The service allows you to track all your orders and shipping in one place," and adds a link to a quick video tour.

grammar fascist writes "CNN reports that Northrop Grumman is under contract to build a new supersonic, shape-shifting bomber by 2020. The main innovation is in its single, rotating wing. From the article: '[It] will cruise with its 200-foot-long wing perpendicular to its engines like a normal airplane. But just before the craft breaks the sound barrier, its single wing will swivel around 60 degrees (hence the name) so that one end points forward and the other back. This oblique configuration redistributes the shock waves that pile up in front of a plane at Mach speeds and cause drag. When the Switchblade returns to subsonic speeds, the wing will rotate back to perpendicular.'"

dhollist writes "A story just released by the Inquirer shows that 80% of incoming search requests from Microsoft's domain arrived via Google's search engine. In contrast, 64% of Yahoo! staff and 100% of Google staff use their own company's search engine. How's that for a product endorsement? I'd guess that Microsoft may soon add google.com to the list of blocked URL's on their intranet."

Nirnimesh writes "Google reveals their ranking system for videos on the official blog. The system lists videos according to their country-wide popularity. From the article: 'We use algorithms to identify videos that are suddenly becoming popular, and then rank them based on how popular they are -- and how suddenly they became popular. We've been using this list internally, and now it's ready to share with you, so check it out. Right now this feature highlights videos from close to 40 countries, including Argentina, Australia, Belgium, Brazil, Canada, Estonia, Finland, Greece, Hong Kong, India, Israel, Japan, South Korea, Mexico, and New Zealand, to name a few.'"

Snap E Tom writes "According to a Washington Post poll, a majority (63%) of Americans 'said they found the NSA program to be an acceptable way to investigate terrorism.' A slightly higher majority would not be bothered if the NSA collected personal calls that they made. Even though the program has received bi-partisan criticism from Congress, it appears that the public values security over privacy."

Roland Piquepaille writes "According to EE Times, an Israeli company has developed a personal video display device that looks like a simple pair of glasses. You can use these glasses with various sources, such as a portable media player or your cell phone. This technology promises to eliminate the dizziness phenomenon usually associated with this kind of display. And with these glasses weighing only about 40 grams, you'll feel that you're viewing a 40-inch screen from a distance of 7 feet." Video screens embedded into eyewear isn't that new, but the footprint of these is smaller than what I've seen before, making them cooler to wear on the subway.

Roland Piquepaille writes "Scientists from the Pacific Northwest National Laboratory (PNNL) have developed a technique to force a variety of enzymes to self-assemble layer-by-layer on carbon nanotubes (CNTs) with the help of noodle-like polymer molecules. In 'A biosensor layered like lasagna,' the researchers say that this technique can be applied to a wide range of applications. In particular, it will be possible to build other biosensors "that react specifically with other biological chemicals, environmental agents or even microbes." Read more for additional details and the most spectacular scientific image of the month."

SoySauc writes "From a story on the New Scientist site: 'A soccer-ball-sized satellite will soon be floating aboard the International Space Station. Once joined by two others, it will help researchers test formation flying and autonomous rendezvous and docking maneuvers for future orbiting satellites.' NASA's DART mission was designed to do the same thing, but in 2005 shut itself down and bumped into the satellite it was only meant to approach."
