Tiny magnetic robot armies could treat bleeds in the brain and'open new frontiers in medicine', experts have found. Researchers have created nanoscale robots – each about a twentieth of the size of a red blood cell – that can be remotely guided as a swarm. It is hoped they could enable precise, low-risk treatment of brain aneurisms, which cause around half a million deaths a year globally. The condition – a blood-filled bulge on a brain artery that can rupture and cause fatal bleeds – can also lead to stroke and disability. The team, co-led by the University of Edinburgh's School of Engineering, carried out lab tests using models of aneurisms and rabbits.

Artificial intelligence (AI) is now a reality, and want it or not, it soon will be part of our daily lives. In a recent study, Bank of America Merrill Lynch predicted that the artificial intelligence market will blossom to $153 billion over the next five years: $83 billion for robots and $70 billion for artificial intelligence-based systems. Facebook's CEO Mark Zuckerberg believes that virtual robots powered by artificial intelligence are bound to transform the way companies interact with their customers. In a world where disruption has become the norm, super-intelligent machines have the potential to revolutionize businesses while benefiting users and society in general. But as these smart personal assistants blend into our environment, many questions arise.
