SWISS DATA BANK: It's huge, underground and in Switzerland. The Large Hadron Collider? Well, yes, but also another facility: the world's toughest server farm. A former Cold War nuclear bunker is now the home of a fortified data repository. It has its own power supply and cooling system, in fact all the systems it needs to be self-sufficient in a catastrophe. Backup your holiday photos: no; backup the human genome sequence: yes.

EYE SPEED: Traditional eye-tracking devices often can't keep up, but a robotic camera from Germany mimics and can even exceed the speed of human eyes. The system uses ultrasonic piezo actuators and prismatic joints to precisely follow an eye it's tracking. The device could also be used for robot eyes. Augmented vision for tennis players and cricketers? More at Spectrum and video on YouTube.
