By analyzing seismic waves from earthquakes from the 1960s, researchers from Peking University deduced that the Earth's inner ...

What water, chemistry and temperature cycles fostered the chemical reactions that allowed life to emerge on our planet? Because life arose in the largely unknown surface conditions of Earth’s early ...

By exposing organic molecules to repeated wet-dry cycles, researchers observed ... the molecular complexity needed for life to emerge. To simulate early Earth, the team subjected chemical mixtures ...

Research shows how Earth's climate suddenly warmed 10°C, transforming ecosystems and causing the worst mass extinction in history.

unnoticed ways the Moon shapes the course of life on Earth. 'The Moon has been up there as long as evolution has been taking place, and lunar rhythms are embedded in the life cycles of many organisms, ...

All organisms on Earth ride upon a "ferrous wheel" made of different forms of iron that are essential for life. Aa Aa Aa Biogeochemical cycles describe pathways by which chemical elements move ...

A team of researchers say their latest attempts to understand how molecules chemically reacted to form the basic building blocks of life on Earth are promising. There has long been debate about the ...
