In a stunning breakthrough, scientists have upended decades of accepted thinking about reverse osmosis. Reverse osmosis is a process used to create fresh water from salt water, and it is widely used to desalinate water in arid regions. Until now, scientists believed that reverse osmosis relied on pressure to push the water through a membrane that captured the salt molecules. However, a team of researchers has discovered that the process is instead driven by a water-repelling surface. This research overturns the decades-long accepted theory of reverse osmosis and could have implications for improving the process and making it more efficient.
