Green hydrogen is going to demand a lot of water for electrolysis – nine liters of pure water for every kilogram of hydrogen. Researchers say they've found a simple way to use seawater in standard electrolyzers, and that's big news for clean energy.

We generally picture lasers as being encased within hard housings, much like most other electronics. Thanks to new research, however, we could soon see sensors or other devices that incorporate stretchable laser-emitting rubber.
