A new, better way to desalinate water

Researchers have created new, more efficient desalination membranes. The new membranes can remove salt from the water. A team led by the King Abdullah University of Science and Technology (KAUST) has shown how polymer-based ultrathin membranes can remove salt from brine and seawater, providing a potential alternative to current desalination systems. “Desalination membranes should simultaneously …

Scientists just found a sixth mass extinction hidden in Earth’s ancient past

The height of the Ediacaran period, about 550 million years ago, was a flowering period for life in the Earth’s oceans. Petalonamids in the form of feathers absorb nutrients from the water, like a slug Kimberla They were grazing on microbial mats, and the ancestors of the jellyfish were just starting to make waves. But …
