By resurrecting a 3.2-billion-year-old enzyme and studying it inside living microbes, researchers at the University of ...

New method reveals chemical signs of early microbial life in ancient Earth rocks, showing photosynthesis evolved much earlier ...

Scientists say they have found geochemical traces of Earth’s ancient self hidden far below our feet, suggesting that parts of the planet that existed before the Moon-forming collision 4.5 billion ...

Millions of years before blue oceans and wandering continents, the Earth in its early days was a molten, tumultuous planet — a roiling mixture of rock and metal condensing within the nascent solar ...

New Curtin University research has revealed how massive ancient glaciers acted like giant bulldozers, reshaping Earth's surface and paving the way for complex life to flourish. The key to unlocking ...

Some 2.3 billion years ago, the Earth would have been unrecognizable to us. At that time, ancient microorganisms were the dominant life form; there were no animals, no plant life, and certainly no ...

New research suggests that the explosive death throes of massive stars, known as supernovas, may have had dramatic effects on our planet's climate over its distant history. Investigating historic ...

Scientists believe they’ve found evidence that life on Earth is over a billion years older than anyone believed was realistic. New research used machine learning to scan ancient meteorites and fossils ...

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

New research shows ancient tropical oceans once held more oxygen than cooler regions, reshaping where early life could ...

What types of animals first existed on Earth long ago? This is what a recent study published in the Proceedings of the National Academy of Sciences hopes to address as a team of scientists ...
