When plant roots learned to follow gravity

Highly developed seed plants evolved deep root systems that are able to sense Earth's gravity. The how and when of this evolutionary step has, until now, remained unknown. Plant biologists at the Institute of Science and ...

The dirt on soil loss from the Midwest floods

As devastating images of the 2019 Midwest floods fade from view, an insidious and longer-term problem is emerging across its vast plains: The loss of topsoil that much of the nation's food supply relies on.

Plant hormone makes space farming a possibility

When roots crack and worms crunch

Roots can be "listened to" while growing – and worms when burrowing. Researchers from ETH Zurich and the French National Institute for Agricultural Research present a new method for soil analysis.

Research finds roots use chemical 'photos' to coordinate growth
