Australian researchers have invented a new clock that will bring atomic accuracy to your desk.

Skype, online games, air traffic control, smart energy grids – all rely on accurate timing across the internet. But our present computers aren’t accurate enough. They can synchronise with an atomic clock over the internet. But even tiny delays across the network introduce errors – your video conversation gets out of sync, you lose your online game, or the electricity grid wastes power. [click to continue…]

Imagine printing your own room lighting, lasers, or solar cells from inks you buy at the local newsagent. Jacek Jasieniak and his colleagues at CSIRO, the University of Melbourne and the University of Padua in Italy, have moved a step closer to such a future, by developing liquid inks based on quantum dots that can be used to print devices.
