Learn how plants communicate through chemical signals, and why losing biodiversity can disrupt these hidden communication ...

Plants do not stay silent. New research shows how plant diversity changes smell based communication across ecosystems.

Every other Friday, NHPR's Outside/In team answers a listener question about the natural world. This week’s question comes from Jenna in Cupertino, Calif. How do plants communicate with each other?

In the 1960s and '70s, a series of questionable experiments claimed to prove that plants could behave like humans, that they had feelings, responded to music and could even take a polygraph test.

Researchers at Purdue University and UC Davis have found that petunias cannot properly form reproductive structures without chemical signals delivered between different parts of the plant. The work ...

In Lena Mueller’s lab at the Salk Institute for Biological Studies, dead plants are OK. “Don’t worry, it’s on purpose,” said Kelly Semtner, Mueller’s high school intern, gesturing at a row of wilted ...
