Disabled violinist uses thoughts to make music for the first time in 27 years

This is incredible.

Rosemary Johnson was a promising violinist and member of the Welsh National Opera Orchestra when she was involved in a devastating car crash 27 years ago. The accident left her in a coma for seven months, and the resulting brain damage has robbed her of most of her ability to talk and move.

But thanks to new software that reads people’s brain waves, Johnson has been able to compose music for the first time since 1988, and has had the chance to have it played to her in real time by a professional string quartet.

“It was really very moving,” Eduardo Miranda from the Interdisciplinary Centre for Computer Music Research at Plymouth University in the UK, told The Telegraph.

These are the Most Incredible Photos Shot by NASA’s Cassini Probe

The Cassini space probe has captured its fair share of eye-popping photos since launching in 1997 and arriving in Saturn’s orbit in 2004. Here’s a collection of some of Cassini’s most remarkable photographs. Many of them were compiled by Reddit user I_Say_I_Say, and others were featured here before or obtained from NASA’s website: You can find a massive collection of Cassini’s photos in the mission gallery on NASA’s website.Thanks Petapixel

Physicists have broken the record for the most accurate clock ever built

This could redefine what a second is.

Physicists in Germany have built the most accurate timepiece on Earth, achieving unprecedented levels of accuracy with a new atomic clock that keeps time according to the movements of ytterbium ions.

Called an optical single-ion clock, the device works by measuring the vibrational frequency of ytterbium ions as they oscillate back and forth hundreds of trillions times per second between two different energy levels. These ions are trapped within an ‘optical lattice’ of laser beams that allows scientists to count the number of ytterbium 'ticks’ per second to measure time so accurately, the clock won’t lose or gain a second in several billion years.

Until very recently, our most accurate time-keepers were caesium atomic clocks - devices that contain a 'pendulum’ of atoms that are excited into resonance by microwave radiation. It’s on these clocks that the official definition of the second - the Standard International (SI) unit of time - is based.
