Device inspired by mangroves could help clear up flood water

Researchers say their synthetic system reproduces tree's ability to desalinate water

A novel approach to removing salt from water, inspired by mangrove trees, has been revealed by researchers who say the system could offer an unusual approach to clearing up flood water.

Mangroves, like other trees, employ a system of water transport: it is thought evaporation of moisture from their leaves produces a negative pressure in their water-conducting tissues that helps to draw water into their roots and up their trunks.
