Scientists have created tiny carbon nanotubes that can filter water very efficiently, and could one day help turn seawater into drinkable water.

The nanotubes work similarly to certain biological proteins used to filter water in living cells, but they’re six times more efficient, according to a study published today in Science. Though the nanotubes weren’t used to desalinate actual seawater, the researchers showed that they can successfully filter water that’s just as salty. To be able to desalinate seawater, the nanotubes will have to be able to withstand much higher pressures.

The idea for the nanotubes came from natural proteins called aquaporins, says study co-author Aleksandr Noy, an associate adjunct professor at the University…
