Pico projectors are an easy way to increase the screen real estate of your mobile phone, but what if you'd rather not carry one around in your pocket or bulk up your phone's slim profile with a slip on solution? Well, a team of intrepid researchers may have come up with an elegant solution to your problem that can work with any smartphone and external display: virtual projection. The system works by using a central server that constantly takes screenshots of the external display and compares them with the images from the phone's camera to track its location. It then replicates what's on the handset's screen, while allowing you to add multiple image windows and position and rotate them as you see fit. Additionally, multiple users can collaborate and virtually project pictures or videos onscreen at the same time. Intrigued? See it in action for yourself in the video after the break.

If your car was powered by thorium, you would never need to refuel it. The vehicle would burn out long before the chemical did. The thorium would last so long, in fact, it would probably outlive you. That's why a company called Laser Power Systems has created a concept for a
World's first 3-D acoustic cloaking device hides objects from sound: http://phy.so/313776247
(Phys.org) —Using little more than a few perforated sheets of plastic and a staggering amount of number crunching, Duke engineers have demonstrated the world's first three-dimensional acoustic cloak. The new device reroutes sound waves to create the impression that both the cloak and anything beneath it are not there.

Have you ever thought about becoming an asteroid hunter? http://bbc.in/1dMYIjH
#Nasa, the US space agency, is seeking coders who could help prevent a global catastrophe by identifying asteroids that may crash into Earth. Its Asteroid Data Hunter contest will offer $35,000 (£21,000) to programmers who can identify asteroids captured by ground-based telescopes.
The winning solution must increase the detection rate and minimise the number of false positives.
