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.
- Ecosystems
Scientists Say: Food web
All the species in an ecosystem and the feeding relationships between them get summed up with this handy picture.

Sea life may suffer as plastic bits alter metals in water
This interplay between plastics and metals could affect how each affects the environment — and suggests opportunities for controlling their risks.
- Chemistry
Scientists Say: Rubisco
Rubisco is a key protein in the process of photosynthesis, which feeds plants — and, in turn, us.

This chemist uses online videos to teach about the perils of microplastics
Imari Walker says her journey as a scientist and science communicator lets her talk about and advocate for her passion.

Bacterial ‘living wires’ could help protect the seas and climate
Long, thin bacteria that conduct electricity may be able to help clean up oil spills and reduce emissions of methane, a powerful greenhouse gas.

What does charred ancient poop reveal about early animal-raising?
Evidence from the dung may push the onset of animal raising back 2,000 years earlier than previously thought.

No sun? No prob! A new process might soon grow plants in the dark
Teamwork makes green-work! Collaborating scientists came up with an electrifying farming trick that could make sunlight optional.

Ponds made to control floods can spew climate-warming gases, study finds
Younger stormwater ponds can release more carbon in gases than they absorb, a study finds. That could aggravate global warming.
- Environment
Widely used pesticides may threaten Earth’s ozone layer
Data show a major class of long-used “eco-friendly” copper chemicals unexpectedly react with soil, making gases harmful to Earth’s protective ozone layer.
- Ecosystems
Scientists Say: Decay
This word can refer to rotting flesh or the transformation of radioactive atoms.
