Jellyfish blooms can cause havoc, scaring away tourists, clogging up fishing nets, and even getting stuck in power station cooling pipes. But scientists are finding ways to use the creatures to help us solve some big problems. They think jellyfish mucus could filter microplastics from our water systems, and their collagen could help us develop new medicines. And some want to see jellyfish on our plates.

A growing number of police departments in the US are introducing a new concept in their training - teaching officers on the beat how to step in when they see a colleague doing something they don't think is right. After the killing of George Floyd and the Black Lives Matter protests, a programme pioneered by police in New Orleans is being developed for other forces.

It’s not just search engines that are powered by artificial intelligence. From the courts to the jobs market, AI is influencing decisions that have a big impact on people’s lives. But researchers now believe that not all people are treated equally by some algorithms. They’ve found potential bias - influenced by race, class and gender - can have an impact on the decisions that computers make. Some programmers, computer scientists and entrepreneurs hope to fight this bias, using the technology that created it in the first place. Produced and presented by Craig LangranImage: Getty Images
