Researchers have made a breakthrough in filtering interference from radar sensors used in autonomous driving: the results far surpass the current state of the art.

A research team from the Swiss Federal Institute of Technology Lausanne (EPFL) has presented a prototype of a low-cost filter that efficiently decontaminates water using only sunlight. The device is intended to provide clean drinking water for people in regions with little electricity.

To slow down climate change, a new type of plant in Iceland filters CO2 from the air. This is then mixed with water and injected into basalt. There it petrifies.
