Leap Motion. Most Wanted Stuff. Ever since the iPhone debuted in 2007, people have been looking for a good way to integrate it into their cars.

Most Wanted Stuff

Some used dash mounts, some rely on Bluetooth, but nearly every option relied on you using the iPhone itself. But no more. Arriving on select models this year, Apple CarPlay integrates your iPhone 5, 5C, or 5S with your car's existing controls and infotainment screen, letting you use Siri, the car's touchscreen, or even various knobs and controls to do things like get directions, make and answer calls, send and receive texts, and play music, all while enjoying an Apple-designed, iOS-like interface that's worlds better than the built-in mess you're used to.

3-D Printer with Nano-Precision. Printing three-dimensional objects with incredibly fine details is now possible using "two-photon lithography.

3-D Printer with Nano-Precision

" With this technology, tiny structures on a nanometer scale can be fabricated. Researchers at the Vienna University of Technology (TU Vienna) have now made a major breakthrough in speeding up this printing technique: The high-precision-3D-printer at TU Vienna is orders of magnitude faster than similar devices. This opens up completely new areas of application, such as in medicine. Setting a New World Record The 3D printer uses a liquid resin, which is hardened at precisely the correct spots by a focused laser beam. This amazing progress was made possible by combining several new ideas. Photoactive Molecules Harden the Resin 3D-printing is not all about mechanics -- chemists had a crucial role to play in this project too. Researchers all over the world are working on 3D printers today -- at universities as well as in industry. Video: Sculpting in Blender 2.59 (Part 1)
