The world's thinnest transparent screen isn't really a screen at all, but something more like a soap bubble. An international team of researchers claims its display - which uses ultrasonic sound waves to change the properties of a soap-like film to display both flat and 3D images - is the world's thinnest transparent screen, and that using several of them together can even produce a holographic projection.

Last October, Acer and Asus debuted the first ultrabooks, a class of laptops characterised by their super-thin chassis. The trim designs, however, left engineers little room to include graphics cards or large, fast processors.

It's official: the US Supreme Court has upheld the Affordable Care Act, which, however you feel about it, means 32 million Americans will likely gain health care coverage. A part of the legislation dictates that all those people, by law, need somewhere to enroll, compare coverage, and purchase insurance. The design consultancy Ideo has spent more than a year putting together an open-source template to keep the potential paperwork from crushing everyone before they even have health insurance to cover the damage.

Computers get hot. Heat is bad for computers. To whisk it away, we use a combination of heatsinks and fans to snatch heat away from the internals and blast it out of the computer's case.

The Pro is for, well, pros.
