New ultrathin materials can pull climate-warming CO2 from the air
To slow global warming, we’ll need help from CO2-trapping materials. Enter MXenes. They’re strong and reactive — and they love to eat up CO2.

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.
