Scientists have decoded the atomic structure of Photosystem I from a 3-billion-year-old cyanobacteria lineage, offering a unique look at early oxygen-producing photosynthesis. The ancient nanodevice, ...

Researchers uncovered that trace compounds like nickel and urea may have delayed Earth’s oxygenation for millions of years. Experiments mimicking early Earth revealed how their concentrations ...

Explore the history of life on Earth, from 3.5-billion-year-old fossils to the vast diversity of species on our planet today.

To better understand the circadian clock in modern-day cyanobacteria, a Japanese research team has studied ancient timekeeping systems. They examined the oscillation of the clock proteins KaiA, KaiB, ...

There are photosynthetic bacteria known as cyanobacteria, and these microbes helped generate the oxygen that paved the way ...

The appearance of oxygen in Earth's atmosphere was a turning point in the history of our planet, forever transforming the environment and setting the stage for complex life. This event, known as the ...

An international team of scientists have unlocked a key piece of Earth’s evolutionary puzzle by decoding the structure of a light-harvesting "nanodevice" in one of the planet’s most ancient lineages ...
