New research sheds light on how and when stars in our galaxy made carbon, "ending up within the raw material from which the sun and its planetary system..."

Poorly planned tree-planting efforts may risk actually adding to climate change and cutting biodiversity, research on a campaign in Chile finds.

Plants don't just get carbon from photosynthesis, new research suggests. Up to 40% may also get a portion from fungi in their roots.

Though scientists knew the black smoke from cookstoves contained dangerous carbon, new research indicates that's only half the problem.

“People have been arguing about whether these long-lived pioneers contribute much to carbon storage... We were surprised to find that they do."

Despite difficulties, the chemical industry really can become carbon neutral, researchers say. They identify three ways that it could happen.

Researchers were baffled when they lined up nanotubes side by side like dry spaghetti. New research explains how it happened.

Aerial maps of tropical forests that show the chemistry of the canopy could shed light on how forests will react to climate change.

A new theory involving volcanoes may partly explain the appearance of the first oxygen on Earth 2.5 billion years ago, researchers say.

Scietists have puzzled over the existence of buckyballs in space, but a new idea about how the carbon molecules form could solve the mystery.
