Five people have been able to perceive a colour never before seen by human eyes, after researchers used lasers and tracking technology to selectively activate certain cells in their retinas. The blue-greenish hue has an intensity, or ‘saturation’, outside the natural range of colours seen by humans. The work is “amazing technically” and an “extraordinary achievement”, says Kimberly Jameson, a colour-vision scientist at the University of California, Irvine.

Physics are sketching the designs of a particle accelerator that would be radically smaller and cheaper than existing facilities. The technique behind these designs, known as wakefield acceleration, has been studied since the 1970s but is now making rapid advances. CERN’s pioneering mini-accelerator passes first testPhysicists use accelerators to study particles in intense detail, and, they hope, to discover new ones.

Researchers have broken a distance record in quantum communication by sending a secret encryption key nearly 13,000 km from China to South Africa, using a cheap, lightweight ‘microsatellite’. The satellite was able to send pulses of laser light, put into special quantum states, from a rooftop in Beijing to another at Stellenbosch University near Cape Town. The pulses formed a quantum key that was used to encrypt two images — one of China’s Great Wall and one showing part of Stellenbosch’s campus.

Physicists have, for the first time, seen a matter particle from the proton family behave fundamentally differently to its antimatter twin. The finding — which fits with behaviours predicted by the standard model of particle physics — could help researchers in their struggle to explain why matter is so abundant compared with antimatter, something that current theories cannot do.

A team led by China's Jian-Wei Pan has created a fridge-sized, 23kg satellite that can perform quantum key distribution in space & used it to transmit a secure image 13,000km. A quantum secure network that spans the globe is not far away. My @Nature story: https://t.co/YED2nvylo3
Here's a fascinating claim to have made electricity using a static ceramic tube. Not a perpetual motion machine, it takes energy from Earth's rotation, say researchers, creating a current as the tube moves through Earth's magnetic field. Many are sceptical https://t.co/7tIjdXjkYH
RT @LongFormMath: I think this has a legitimate case to be the most startling identity in mathematics. It’s a simple, natural sum involving…
