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.

Photosynthesis can take place in nature even at extremely low light levels. This is the result of a study that investigated the development of Arctic microalgae at the end of the polar night. The ...

Photosynthesis in plants and a few bacteria is responsible for feeding nearly all life on Earth. It allows energy from the Sun to be converted into a storable form, usually glucose, which plants use ...

Most plants split water molecules to generate energy, and now we have a clearer picture of exactly how they do it. Researches have found missing steps in photosynthesis by stimulating plant proteins ...

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, ...
