We could have more arms like Doctor Octopus
Humans will learn how to use third arms within the next 30 years, according to scientists at Cambridge University.
A team is working on a high-tech extra limb that could give humans extra grabbing power like the 'Spider-Man' villain Doctor Octopus.
It would be strapped onto the body and controlled by small movements in the user's natural arms and legs.
Professor Tamar Makin, at Cambridge, said: "The technologies are already out there. There are issues to deal with - for example, if you want to be comfortable - but control is the real issue."
The extra limbs can help people with daily tasks such as drinking cups of coffee but boffins are warning that the brain will need to adapt to the additions.
