A new study shows that iron-bearing rocks that formed at the ocean floor 3.2 billion years ago carry unmistakable evidence of oxygen. The only logical source for that oxygen is the earliest known ...

Photosynthesis is the starting point for almost every food chain, sustaining most life on Earth. You would be forgiven, then, for thinking nature has perfected the art of turning sunlight into sugar.

An ancient lineage of cyanobacteria is helping biologists uncover an early evolutionary stage of the mind-boggling process ...

How can chemical reactions be triggered by light, following the example of photosynthesis in nature? This process is still poorly understood. However, researchers have now uncovered a major piece of ...

Since the early 2000s, the growing level of carbon dioxide in the atmosphere has led to an increased rate of photosynthesis around the world, climate scientists have found. Plants produce energy ...

Photosynthesis is the process that enables plants to take sunlight and carbon dioxide and convert it into chemical energy to grow. Crop plants, however, are only about 1% efficient at doing this, ...
