Virtual reality has been used to help treat severe paranoia.

Patients who suffered persecutory delusions were encouraged to step into a computer-generated Underground train carriage and a lift.

The simulations allowed the study's 30 patients to learn social situations they feared were actually safe.

The research at Oxford University, published in the British Journal of Psychiatry, was funded by the Medical Research Council.

Members of one group of patients were told to use their normal defensive behaviour, such as avoiding eye contact.

A man who was paralysed from the chest down after a knife attack in 2010 can now ride an adapted tricycle.

In 2014, surgeons in Poland announced they had reversed Darek Fidyka's paralysis using cells taken from his nose to repair his spinal cord.

Why brains are beautiful

Media captionFergus Walsh discovers why the brain is a marvel of evolution

When I picked up the human brain in my hands, several things ran through my mind. My immediate concern was I might drop it or that it would fall apart in my hands - fortunately neither happened.

Second, I was struck by how light the human brain is. I should say this was half a brain - the right hemisphere - the left had already been sent for dissection. The intact human brain weighs only around 3lbs (1.5kg) - just 2% of body-weight, and yet it consumes 20% of its energy.

What's the best way to avoid air pollution travelling in a city? Walking, cycling or in a vehicle?

It's a question I put a few months ago when testing some mobile pollution monitors along the busy Brompton Road in London's Knightsbridge.

Researchers in the US have used gene editing to treat mice with Duchenne muscular dystrophy.

A team at Duke University used a system known as CRISPR-Cas9 to delete DNA that was preventing cells from producing a protein essential for muscle function.

An international meeting of leading scientists has said it would be "irresponsible" to allow the creation of genetically altered humans.

But they said basic research involving embryo gene editing should continue in order to improve understanding of human biology.
