Photosynthesis is one of the most important processes on Earth. It is the method by which green plants, algae, and some ...

Microscopic ocean algae produce a huge share of Earth’s oxygen—but they need iron to do it. New field research shows that when iron is scarce, phytoplankton waste energy and photosynthesis falters.

Take a deep breath. Now take nine more. According to new research, the amount of oxygen in one of those 10 breaths was made possible thanks to a newly identified cellular mechanism that promotes ...

For generations, we’ve been taught a simple rule: oxygen comes from sunlight. Plants, algae, and microscopic phytoplankton use light to power photosynthesis, releasing the oxygen that fills our ...

Life on Earth owes its existence to photosynthesis – a process which is 2.3 billion years old. This immensely fascinating (and still not fully understood) reaction enables plants and other organisms ...

Oxygen, the molecule that supports intelligent life as we know it, is largely made by plants. Whether underwater or on land, they do this by photosynthesizing carbon dioxide. However, a recent study ...

Bacterial evolution and oxygen adaptation: A timeline built from genomic, fossil, and chemical data. Colors show oxygen states: anaerobic (blue), aerobic (red), and proportion of aerobic lineages in ...
