#105: Electrodes treat paralysis; first detected isolated black hole; the ancient human inhabitants of a French cave; breakthroughs in transplant organs from pigs; why you should pick up your dog’s poo

Three men paralysed from the waist down have regained their ability to walk. They’re the subjects of a breakthrough operation which involves implanting electrodes in the spine. The team explains how the method works.

Astronomers have detected an isolated black hole for the first time ever. Despite being 5000 light years away and incredibly difficult to spot, the team explains how the Hubble Space Telescope was able to do it.

A cave in France is providing us with an intriguing snapshot of human activity in France 54,000 years ago. The team says Neanderthals and modern humans appear to have crossed over, moving in and out of a site called Grotte Mandrin as if it were a prime piece of real estate.

With so many major developments in using pig organs for transplants, the team finds out how gene editing has catapulted xenotransplantation forward and look ahead to how else this technology could be used.

And they also look at a study that suggests dog poo may be having a harmful impact on wildlife and biodiversity.
