Turning jeans blue with sunlight might help the environment
When dipped in indican and exposed to sunlight, yarn turns a deep blue. This process is more eco-friendly than the current denim dyeing method.
- Materials Science
Scientists Say: 2-D Material
Two-dimensional materials such as graphene could improve electronics, carbon capture and more.

Let’s learn about graphene
Scientists have been trying to understand and harness this material’s superpowers since its discovery in 2004.

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.

Pollution power? A new device turns carbon dioxide into fuel
Scientists made a device that converts the greenhouse gas into formate. This salt can then run a fuel cell to make electricity.
- Environment
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.
- Materials Science
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.

Creation of quantum dots wins 2023 chemistry Nobel
The award honors three scientists who discovered and built quantum dots, which are now used in everything from TVs to medical tools.
- Chemistry
Scientists Say: Rare earth element
Rare earth elements aren’t all that rare — but skyrocketing demand for these metals makes them precious.

Made from fungi, this vegan leather can self-heal holes or rips
If made under gentle conditions, leather formed from the “roots” of mushrooms can retain the ability to regrow and repair minor damage.
