If you're prone to lying about your age, steer clear of structural magnetic resonance imaging. When used to scan your brain, no matter how good (or bad) you may look, a new imaging technique that uses MRI won't lie. In fact, it probably knows your age to the exact year.

"We have uncovered a 'developmental clock' of sorts within the brain -- a biological signature of maturation that captures age differences quite well, regardless of other kinds of differences that exist across individuals," Timothy Brown of the University of California, San Diego School of Medicine says in a news release.… Read more

Is there a paint color called "crack in the bridge?"

There could be one day, if Scottish researchers continue to make progress on a low-cost smart paint that could detect microscopic faults in structures such as bridges, wind turbines, and mines.

The paint, under development at the University of Strathclyde in Glasgow, is made of highly aligned carbon nanotubes, which can carry an electrical current, and a recycled waste product known as fly ash that's usually produced during coal combustion.

When mixed, the paint takes on a cement-like property that makes it hardy and particularly useful in areas where the weather can make regular safety monitoring difficult.

"There are no limitations as to where it could be used, and the low-cost nature gives it a significant advantage over the current options available in the industry," Mohamed Saafi, chair of the university's department of civil engineering, said in a statement. "The process of producing and applying the paint also gives it an advantage, as no expertise is required and monitoring itself is straightforward." … Read more

Swiss scientists say they have a new candidate for making flexible electronic devices, after they successfully manufactured the first molybdenite microchip.

The integrated circuit was made at the Laboratory of Nanoscale Electronics and Structures (Lanes), of the Ecole Polytechnique Federale de Lausanne. Yesterday, the researchers said it showed how molybdenite microchips could be made smaller than silicon chips, use less electricity than silicon, and be more flexible than silicon, the mainstay of today's computers.

The flexibility of molybdenite could also make it suitable for creating rollable computers or devices that can be attached to a person's skin, the … Read more

Angry Birds Seasons lets you play the popular birds vs. pigs game, but with themes that match every season. You can play among jack-o'-lanterns and white-sheet ghosts in the fall; snowmen and Santa-capped pigs during the winter; or brightly colored eggs and bunny hats when it gets close to Easter. You can play whichever season you want right away--you won't need to unlock every level in order to unlock new themed worlds. With that said, the gameplay is no different than you've come to expect with Angry Birds, but maybe that's a good thing--most people love … Read more

Metropolis II is a four-year project by performance artist and sculptor Chris Burden that uses more than 1,100 Matchbox-style toy cars curved around 19 roadways to show the last days of what he calls the "free car"--in other words, the independent ability to simply jump in an automobile and travel.

In advance of a Metropolis II exhibit at the Los Angeles County Museum of Art this fall, directors Henry Joost and Ariel Shulman of "Catfish" fame just released this short documentary that shows the 20-foot by 30-foot art installation in action.

More pictures of Metropolis II after the jump.… Read more

Angry Birds Rio is the surprisingly good game tie-in to the animated movie "Rio." While many co-branded marketing vehicles show signs of slipshod shoehorning, Angry Birds Rio expands on the core Angry Birds mechanic while adding some twists and improvements we hope will, ahem, migrate their way into the main game.

Fans of the titanically popular Angry Birds series will find the same basic interface and gameplay--but instead of crushing pigs, your avian assault team is freeing other birds imprisoned by smugglers, taking out menacing monkeys, and presumably doing other things as more chapters are added. (The game … Read more

SimplePhysics is the sequel to popular physics game BridgeBasher, challenging you to make structures that will withstand the laws of gravity and nature--while remaining under budget.

You start with a helpful tutorial level that shows you the ropes by having you build a tree house. Your requirements are that you build the structure to withstand the weight of four 50-pound children (don't worry, they use boxes to symbolize the children). Before testing the integrity of your structure, draw supports between onscreen anchors to make sure your tree house will hold. When you're satisfied with your work you can … Read more

It's not often that the applications that we review really impress us, and that's especially true of browser extensions. Our reactions typically range from, "That's kind of cool," to, "This is totally worthless." OutWit Hub is one of the few Firefox add-ons that really wowed us. This innovative extension lets you effortlessly collect images, links, e-mail addresses, and much more from any Web site you choose. We can't say we've ever seen anything like it.

Getting started with OutWit Hub takes some time. We had no idea how to even access … Read more

Ragdoll Blaster 2 Lite is a free 18-level preview of Ragdoll Blaster 2, the much more polished follow-up to physics-based puzzler Ragdoll Blaster.

The interface of Ragdoll Blaster 2 is a lot like its predecessor, but with a brand-new skin. You're still using your touch screen to aim and fire rag dolls from a cannon, but the earlier game's graph-paper-sketch aesthetic has been swapped out for a more realistic, steampunky backdrop, with a cute musical score, cartoony sound effects, and higher production values throughout.

The object of the game is the same: each level has a red-and-white, bullseye … Read more
