Get ready for custom eyeball transplants for people who absolutely must have eyes in the backs of their heads — or pretty much anywhere on their bodies. Researchers at Tufts University just published a paper where they report transplanting working eyes onto the tail of a blind tadpole. Here’s how they did it. More »

Over at the Boing Boing G+ Community , JollyOrc posted this useful tool: a ring that conceals a saw and a handcuff shim A useful tool for covert and undercover operators, those that travel abroad in unstable countries, or anyone at risk of being held unlawfully. The Titanium Escape Ring adds another tool to the operator’s E&E options for escaping captivity. It’s a simple but elegant-looking ring made of titanium, cut from solid barstock and polished to a mirror finish. But unlike all other rings, this one contains a saw and handcuff shim pick combination tool which is completely hidden from view when worn. Located on a finger, its always in the exact area needed to quickly access and deploy, even when handcuffed. The shim can be used to open single-locked handcuffs, while the saw can cut zip-ties, disposable handcuffs, duct tape, rope, and other non-metallic materials. Titanium Escape Ring $80

An anonymous reader writes “An article at Wired shows just how close we are to a 3-D printed car. Jim Kor’s ‘Urbee 2’ design is a lightweight teardrop shape with three wheels. The engine, chassis, and wheels aren’t printed, of course, but much of the car is formed layer-by-layer out of ABS plastic. It takes about 2,500 hours of printer time to create the whole thing. Assembly is easier, though, since many different parts can be consolidated into just a few. ‘To negotiate the inevitable obstacles presented by a potentially incredulous NHSTA and DOT, the answer is easy. “In many states and many countries, Urbee will be technically registered as a motorcycle,” Kor says. It makes sense. With three wheels and a curb weight of less than 1,200 pounds, it’s more motorcycle than passenger car. No matter what, the bumpers will be just as strong as their sheet-metal equivalents. “We’re planning on making a matrix that will be stronger than FDM,” says Kor. He admits that yes, “There is a danger in breaking one piece and have to recreate the whole thing.” The safety decisions that’ll determine the car’s construction lie ahead. Kor and his team have been tweaking the safety by using crash simulation software, but the full spectrum of testing will have to wait for an influx of investment cash.'” Read more of this story at Slashdot.

After rising steadily over the last several months, Bitcoin has reached an all-time high according to data on Bitcoin Charts . As of this writing, Mt. Gox , the most popular Bitcoin trading site (which announced on Wednesday that its operations would move to Silicon Valley), recorded a high price of $33.22 per Bitcoin. There’s no single explanation as to why Bitcoin has continued to rise, accelerating particularly over the last month. That said, it’s been clear that interest in the digital currency has been rapidly rising, as any regular reader of Ars knows. It’s likely that online gambling has played a part. As we’ve reported earlier this year, one Bitcoin-based site took in $500,000 in profit in just six months in 2012—and Bitcoin gambling is set to get even bigger . For now, gambling with the cryptocurrency, like using Bitcoins in general, remains in a legal grey area (which may be part of the appeal as well). Read 3 remaining paragraphs | Comments

Remember the good ol’ days of Pandora ? Well, it turns out that you were living in it until today. Just this afternoon, the music streaming service revealed that it’s become necessary to return to the 40 hour caps from times long ago — only this time around, it applies only to mobile users. If you may recall, Pandora dropped these caps in September 2011, but steeper royalty costs have forced the company’s hand in the matter. What does this mean for you? Well, unless you fit within the four percent of Pandora listeners that jam out on a mobile device for more than 40 hours per month, you’re unlikely to ever notice the change. Meanwhile, heavy users will need to pay $0.99 to continue listening for the remainder of the month. Naturally, you can also lay down $3.99 per month (or $36 per year) for Pandora One, which will kick both those limits and pesky ads to the curb.
