Engineers cook up a new way to tackle CO2: Make baking soda
Engineers have found a material that can collect carbon dioxide from the air. When later mixed with water, it forms baking soda that can be shed in the sea.

A new hydrogel could help pull drinking water from the air
The salty gel absorbs more water from the air than similar gels, even in desert climates. This could provide clean water for drinking or farming.

Ultrasound waves can help remove polluting microplastics in water
The innovative process concentrates microplastics within a flowing liquid. A two-step process then removes the potentially toxic bits.
