Experiment: Can plants stop soil erosion?
Soil erosion washes pollutants into streams and rivers — but plants may help limit that.

This urban gardener is mimicking nature to create healthier plants
Urban garden specialist Kwesi Joseph is experimenting with rock dust and plants. He also helps New York City community and school gardens with gardening problems.

Let’s learn about useful bacteria
Bacteria do many useful jobs almost everywhere on Earth, from the soil to the seafloor to our stomachs.

Here’s why thousands of octopuses gather at the ‘Octopus Garden’
Underwater cameras and other instruments investigated why so many pearl octopuses gather here to mate and nest.

Scientists Say: Marcescence
Autumn turns to winter, yet some trees' dead leaves keep hanging on.

Restoring 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.

Pumping cold water into rivers could help fish chill out
Hundreds of salmon, trout and other fish sought shelter from summer heat in the human-made cool zones. These areas may help fish adapt to river warming.
- 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.

Scientists Say: Mycelium
These fibrous networks are the reason plants think fungi are such "fun guys.”
- Environment
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.
- Environment
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.
