Farmers in India cut their carbon footprint with trees and solar power
Planting trees near crops and pumping water with solar power in India is reducing greenhouse gas emissions from agriculture.

Machine learning and gravity signals could rapidly detect big earthquakes
Large earthquakes make speed-of-light adjustments to Earth’s gravitational field. Researchers have now trained computers to detect the signals.

These six foods may become more popular as the planet warms
Millet, kelp, Bambara groundnut and cassava are resilient, sustainable and nutrient dense — good options for future dinner plates.

Oat and soy milks are planet friendly, but not as nutritious as cow milk
Plant-based milks are better for the environment, but nutrition-wise they fall behind cow milk.

Replacing some meat with microbial protein could help fight climate change
Just a 20 percent substitution could cut deforestation rates and land-use CO2 emissions by more than half by 2050, a new study suggests.

How some sunscreens damage coral reefs
In lab experiments, sea anemones and coral turned oxybenzone into a toxin activated by light. But helpful algae may provide a layer of protection.

How much does eating meat affect nations’ greenhouse gas emissions?
How much meat eating affects worldwide greenhouse gas emissions comes clear in new country-by-country analyses.

Ancient zircons may record the dawn of plate tectonics
A change in gemstone composition starting about 3.8 billion years ago may offer the earliest record of one tectonic plate sliding over another.

Muons spill secrets about Earth’s hidden structures
Tracking travel patterns of subatomic particles called muons helps reveal the inner worlds of pyramids, volcanoes and more.

Coastal cities around the globe are sinking
Of 99 coastal cities, nearly one-third are sinking in some places at more than a centimeter per year, making them more vulnerable to rising seas.

How ancient, recurring climate changes may have shaped human evolution
Climate changes drove where Homo species lived over the last 2 million years, with a disputed ancestor giving rise to H. sapiens, a new study claims.

More than 57 billion tons of soil have eroded in the U.S. Midwest
Researchers discovered startling soil erosion rates in the Midwest. Farming has worsened erosion, but no-till practices and cover crops can help.
