Scientists say their Stomata In-Sight tool can observe plants "breathe," which could be used to bioengineer crops that require less water, making them potentially more resilient to climate change.

When wildfire smoke is in the air, doctors urge people to stay indoors to avoid breathing in harmful particles and gases. But what happens to trees and other plants that can’t escape from the smoke?

For the first time, scientists have captured real-time videos of plants 'breathing' by observing their leaf pores, called stomata, opening and closing. This groundbreaking footage reveals how these ...
