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.

Let’s learn about why summer 2023 was so hot
Human-caused climate change has played a big role in this summer’s historic heat.
- Oceans
Summer 2023 is when the ocean first turned ‘hot tub’ hot
Unfortunately, scientists worry that this atypical sea warming may actually be the beginning of an unwelcome new ‘normal.’

High-tech solar ‘leaves’ create green fuels from the sun
Chemists make a liquid alternative to fossil fuels from carbon dioxide, water and the sun. Their trick? They use a new type of artificial leaf.

Canada’s Crawford Lake seems to mark when the Anthropocene began
Mud at the bottom of this lake holds a record showing how humanity has been changing our planet. But the Anthropocene isn’t an official new epoch yet.
- Tech
New thermal ‘cloak’ keeps spaces from getting too hot or too cold
A prototype fabric could help keep cars, buildings and other spaces cooler during heat waves while also reducing greenhouse-gas emissions.
- Materials Science
This house is partly made of recycled diapers
After being washed, dried, sanitized and shredded, used diapers were mixed with other materials to make a strong concrete.

For greener toilets and air conditioning, consider saltwater
Using saltwater would allow coastal cities to save their freshwater for drinking and to reduce their carbon footprints. Some could save money, too.

Fungi help rescue crops being harmed by microplastics
Microplastics in the soil hinder plant growth. But two finalists at Regeneron ISEF found that fungi and farm waste can reduce the harm.

Making yards more diverse can reap big environmental benefits
Replacing grass with native plants uses less water and fewer chemicals while providing additional benefits to people and wildlife.
- Tech
A new solar-powered gel purifies water in a flash
The unusual, fruit-inspired structure of this material provides quick filtration that could satisfy people's daily water needs.
