It looks like the gillyweed from the Harry Potter films could one day be a reality.
Scientists have discovered a way for humans to potentially breathe underwater by merging our DNA with that of algae.
In research on salamanders they found that oxygen-producing algae have bonded with their eggs so closely that the two are now inseparable.
By studying the mechanism further, they hope that the same process could be applied to humans one day too.

This would allow us to swim without coming up for air like Harry does in Harry Potter and the Goblet of Fire.
In the film the slimy plant gives Harry gills on the side of his neck and lets him breathe underwater like a fish.

The discovery is the first documented case of a plant living in partnership, or symbiosis, with a vertebrate.
Scientists have said that potentially it could mean that bioengineers could one day use algae as a source of oxygen for other organisms that it pairs with - including humans.
Such a jump would require substantial testing but given we are vertebrates like salamanders, it is possible.
Lead researcher Dr Ryan Kerney said: ‘The algae inside the egg capsules provide oxygen to the embryo and the algae gets waste from the embryo which is rich in the nitrogen the plant needs.
‘We also found algae DNA in the reproductive organs of the adult salamanders, so it seems possible that it is being inherited.
‘We call that vertical transmission, but there is probably a mixture of this and the algae being absorbed from the environment.’
The study was published in Proceedings of the National Academy of Sciences.
