Keeping data forever

We look at three radical new ways to save data: writing inside glass, saving information to tiny magnets, and using the code of life – DNA – to save files.

Could your family photos end up being stored on a piece of glass? Might you find yourself saving a file to DNA storage? Or downloading a video from a data centre in space?

Current methods of storing information are susceptible to decay and have limited capacity but novel approaches could provide plentiful storage so that our selfies outlast our species.
