Scientists have discovered evidence that Earth's oceans were once green, hinting that this could be a marker of early life, ...

It marks the time when cyanobacteria, a type of algae, began producing significant amounts of oxygen through photosynthesis. This oxygen production radically transformed Earth's atmosphere, making it ...

Ancient oceans, which were heavy on iron, interacted differently with light wavelengths, retracting green light into the ...

The study sheds light on life during the Great Oxidation Event, a pivotal time roughly 2.4 billion years ago when ...

They found that longer days extend the period of high sunlight in the afternoon, enabling cyanobacteria to produce and export more oxygen. This extended period of oxygen production reduces the ...

Air apparent: The oxygen revolution (2,500-1,900 mya) As more and more cyanobacteria (blue-green ... colored and gray deposits suggest oxygen production fluctuated over time.

Cyanobacteria are found in almost all aquatic and terrestrial environments on Earth and, through photosynthesis, supply a large portion of the planet’s oxygen. According to ... really fine job ...

In a study published today (October 13) in iScience, researchers found a way to harness photosynthesis to supply neurons with oxygen: they injected either cyanobacteria or green algae into Xenopus ...

From towering trees to the smallest bugs, life on Earth today has been affected by many factors, such as changes in the environment and in our genes. But did you know that billions of years ago ...

Did aerobic metabolism exist before photosynthesis? A newly discovered molecule suggests bacteria could use oxygen before cyanobacteria made it abundant. Life’s oxygen story just got more complex.

Cyanobacteria are probably the most numerous creatures to have ever existed on Earth. They’re good for making oxygen but otherwise bad news for most life forms. Through neglect of our water systems ...
