Photosynthesis transforms solar energy into oxygen and sugar and first arose in bacteria, but the molecular mechanisms involved in the origin and evolution of the existing bacterial phototrophs have ...

Researchers at the University of Liège (ULiège) have identified microstructures in fossil cells that are 1.75 billion years old. These structures, called thylakoid membranes, are the oldest ever ...

Scientists have unraveled the evolutionary journey of a unique type of photosynthesis that allows some bacteria to harness far-red light, a region beyond the visible spectrum. This discovery could ...

Plants use sunlight to convert water and carbon dioxide into energy-rich sugars and oxygen in various ways (photosynthesis). Drought is a major challenge in this process. A research team led by ...

Scientists have shown the importance of hot temperatures in maximizing hydrogen peroxide generation from rocks during the movement of geological faults, and say it may have influenced the early ...

More than 3 billion years ago, on an Earth entirely covered with water, photosynthesis first evolved in ancient bacteria. In the following millions of years, those bacteria evolved into plants, ...

Scientists at Newcastle University have uncovered a source of oxygen that may have influenced the evolution of life before the advent of photosynthesis. While in high concentrations hydrogen peroxide ...
