NSF grant Root slime helps plants eat rocks, sequester carbon

WSU researchers have received half a million dollars to study a microscopic slime that they believe plays an outsized role in life on the planet. The root biofilm is central to the earth’s balance of carbon, how soil is formed, the foundation of plant life and possibly the future of agriculture. Read more.
