An Israeli company called Nano Retina is trialling a device that can help restore sight in blind people. An artificial retinal implant, the Nano Retina chip is placed above the retina and contains a camera-like component that receives the picture through the eye’s natural optics — in other words, it sees what the eye sees. The image is transmitted along the optic nerve to the brain’s neurons, which are capable of receiving and decoding it.

In the hit Netflix show Stranger Things, a mirror world is found under the fictional town of Hawkins. US scientists are now engaging in what they describe as a ‘pretty wacky’ experiment to see if this science fiction concept is plausible. The scientists, from Oak Ridge National Laboratory, have set up equipment to test if it would be possible to find a parallel universe that could be identical in many ways to our own, with mirror particles, mirror planets and possibly even mirror life.

France reached temperatures of 39 degrees Celsius, Spain hit a high of 42 degrees, and the UK saw its hottest day of the year, reaching a balmy 33 degrees Celsius.

Dogs have been referred to as “man’s best friend” for hundreds of years, and thought of that way for thousands. They are friendly, love people, and are able to melt the hearts of most humans with just a look.

Adhesives, well…, adhesives hold the world together. From the Pritt glue children use at school, to the sellotape that comes out of the cupboard for Christmas and birthday presents, to industrial adhesives that are used in the manufacture of everything from machinery to disposable goods, there seems to be an adhesive for everything.

More than 50 years ago, scientists saw that there was something very bright at the centre of our galaxy. That bright object was long thought to be the Milky Way’s central supermassive black hole, named Sagittarius A, which has a gravitational pull strong enough to make stars orbit around it very quickly. Stars close to Sagittarius A orbit as fast as 20 years. In contrast, our solar system takes about 230 million years to circle the centre of the galaxy.

Being a member of South Africa’s government can never be described as boring. Fighting a plummeting GDP figure, junk status, public infighting about the mandate of the Reserve Bank (which led to the sharpest decline in the Rand in a decade), and continued suspicions about corruption, the government is now facing a class-action lawsuit brought by environmental rights groups.
