Why Should I Want This MID
Really, why would I want this MID (Mobile Internet Device) over the current iPhone I use? Lord! I know you’re up to your neck with Apple banging, so for a change let’s compare it to an LG Arena, Samsung I7500 or even BlackBerry Storm 2. Where does this MID score over the rest of these Internet
This Living Human Bone Was Grown In Lab
Scientists have grown real, living human bones in the lab for the first time, completely from scratch, and ready to be inserted inside human flesh. Or given to my dog, as a delicious treat. Dr. Gordana Vunjak-Novakovic—Columbia University professor of biomedical engineering—achieved the fe
Google Wants to Kill JPEGs With New WebP Format
These pictures look the same—but they're not. Because the sign on the right, hypothetically, takes up nearly 40% less space. That's the version in WebP, Google's plan to speed up the internet by slimming down its images. What is WebP? It's a new graphics format that Google hopes will make file
Solar Sail Proves Photon Acceleration Works, as it Twists and Turns Under the Sun
Less than two months after being unfurled in space, Japan's IKAROS solar sail accomplished its ambitious aim—becoming the first spacecraft to travel in space, powered by the sun. Now, it's demonstrated its fine steering ability. Measuring 20m diagonally, the solar sail is made from aluminized![Scientists Discover How to Extend Lifespans without Starving Yourself [Science]](http://gizmodo.com/assets/resources/2008/04/highlander.jpg)
Scientists Discover How to Extend Lifespans without Starving Yourself [Science]
Restricting yourself to a super-low calorie diet has been discovered as a way to extend your lifespan by a noticeable number of years, but it comes with a pretty lousy side effect: you don't get to eat anything. Not worth it! I'd rather die at 70 knowing the sweet taste of ham and cheese Hot Pockets
Why Alcohol Is Good For You
It's one of those medical anomalies that nobody can really explain: Longitudinal studies have consistently shown that people who don't consume any alcohol at all tend to die before people who do. At first glance, this makes little sense. Why would ingesting a psychoactive toxin that increases our
New iPod Shuffle Moves Buttons to Headphones, Adds Text to Speech
Apple has quietly released a new iPod Shuffle design that mimics the original's pack of gum aesthetics. It costs $80, holds 4GB of songs, uses inline controls and boasts text-to-speech. • 4GB or 1,000 Songs • Silver or black color options, stainless steel clip • Controls have been movedTable-Top Black Hole Can Absorb Light

Scientists have created a table-top-sized black hole that absorbs light. And yet we’re still here, and the world hasn’t collapsed. Clearly, my high-school science classes did not adequately explain black holes to me.
The black hole is made from “60 concentrically arranged layers of circuit board,” where each layer (actually created of so-called metamaterials) is coated with copper and “etched with intricate structures whose characteristics change progressively from one strip to the next, so that the permittivity varies smoothly.” Since I can’t even begin to wrap my head around this stuff, I’m going to let the experts explain it:
“When the incident electromagnetic wave hits the device, the wave will be trapped and guided in the shell region towards the core of the black hole, and will then be absorbed by the core,” says Cui [one of the inventors]. “The wave will not come out from the black hole.” In their device, the core converts the absorbed light into heat.
As if it weren’t badass enough that somebody made a black hole small enough to fit on a table-top, the invention has legitimate real-world applications—most notably in solar energy panels. Think about it: You wouldn’t need giant plates to capture the sun if you had a device that attracted light to it. This kind of thing is cool enough to make me want to go back and read more than twelve pages of A Brief History of Time. [New Scientist via Wired]
