EnvironmentNew 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.

EcosystemsRestoring giant underwater forests, one blade at a time
Giant kelp are at risk due to climate change and human activities. In New Zealand, a community effort is rebuilding these underwater algal forests.

PhysicsHeat makes water evaporate. Now it appears light can, too
In the lab, shining light on water made it evaporate faster. This never-before-seen effect, if real, might be happening naturally all around us.

PhysicsA new tool shows tiny changes in the ’24-hour’ length of a day
An underground instrument known as ‘G’ uses laser beams to measure Earth’s rotation — a gauge of day length — with extreme precision.

TechParticles from tree waste could prevent fogged lenses, windshields
A new coating made from a renewable resource — water-loving nanoparticles made from wood — could keep glass surfaces fog-free.

TechBionic plants and electric algae may usher in a greener future
Some can aid the climate by removing pollutants. Others would just avoid dirtying the environment in the first place.

TechBits of trees can make and store energy for us to use
This cellulose and lignin, two major building blocks of trees, could lead to greener electronics.

TechEngineers 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.

Materials ScienceA 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.
