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 ...

It’s not an exaggeration to suggest that the most significant event on Earth was the evolution of photosynthesis. The ability to harvest energy from light freed life from the need to scavenge energy ...

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 ...

Plants use sunlight to convert water and carbon dioxide into energy-rich sugars and oxygen in various ways (photosynthesis).

Plants and trees may seem pretty passive, but behind the scenes, their cells are working hard to put on a magic show. In this episode of Crash Course Botany, we’ll explore how the processes of ...
