Drops of seawater contain traces of an ancient world

Researchers linked chemical changes in seawater to volcanic activity and climate change, with a 7-fold decrease in lithium concentration over the past 150 million years. This shift is attributed to reduced seafloor hydrothermal activity, influenced by tectonic plate movements.

How did Earth get its water?

Researchers propose that early interactions between the magma ocean and a molecular hydrogen proto-atmosphere could have given rise to Earth's signature features, including its abundant water. The study suggests that even dry rocky material collisions would generate large quantities of water through these atmospheric-magma interactions.

Scientists discover a novel origin of abiotic oxidants on early earth: minerals

Researchers have overturned the traditional view that oxygen derives from water splitting, instead finding that reactive oxygen species (ROS) produced at mineral-water interfaces are a key source of oxygen. This discovery has significant implications for understanding the evolution of Earth's atmosphere and the habitability of early life.

Why extinctions ran amok in ancient oceans, and why they slowed down

A new Stanford University study suggests that rising oxygen levels may have slowed down ancient ocean extinctions. The research found that oxygen levels beyond 40% of present atmospheric levels expanded viable ocean habitat and reduced extinction rates. This discovery has implications for understanding the fate of ocean creatures in to...
