The internet amazes me. It's enormous, fast and global. But the hardware we use to send data is reaching its capacity limit.

Researchers have devised a new kind of glass cable which carries data encoded in light. In current internet cables, light beams travel in straight lines. The new cables allow light beams to be twisted so they can carry extra information.

It's good news for data-hungry users. But there are still a lot of people out there with poor internet access shouldn't we focus on getting them connected first?

This research was published in the 27 June 2013 edition of the journal Science.

The new cables could transfer up to ten light beam shapes at once.
