Balsa wood transistors could usher in ‘greener’ electronics
Researchers in Sweden coaxed wood to conduct electricity, then used it to make a climate-friendlier building block of electronics.

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.
- Tech
Particles 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.
- Tech
Bits 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.
- Tech
Bionic 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.
- Climate
Hydrogen energy could help our climate — depending on its source
Hydrogen energy doesn’t emit greenhouse gases when it’s used. But how it’s produced will affect how useful it can be in slowing climate change.

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.
