The appearance of free oxygen in the Earth’s atmosphere led to the Great Oxidation Event. This was triggered by cyanobacteria producing the oxygen which developed into multicellular forms as ...

Early organic carbon got deep burial in mantle Petrology experiments support tectonic role in Earth's 'great oxidation event' Date: April 25, 2017 ...

Geologists have discovered remnants of Earth’s mantle that have persisted for over 2.5 billion years. The ancient rocks were less oxidized than modern ones, indicating that they were exposed to ...

Today's climate change doesn't hold a candle to the chemical warfare waged on Earth more than 2 billion years ago. Before plants discovered the power of photosynthesis, single-celled life survived ...

Also known as rare earth elements, ... But that may change—thanks to a Georgia Tech-led discovery of a new oxidation state for a lanthanide element known as praseodymium.

Science News: In about a billion years, Earth will lose its oxygen, making it uninhabitable for life forms that depend on oxygen. The planet will become methane-ric ...

Before the Great Oxidation Event (GOE) around 2.4 billion years ago—when cyanobacteria helped drastically change the amount of oxygen in our oceans and atmosphere—Earth had very little oxygen.

Researchers studied ancient iron-oxidizing bacteria to understand their role in Earth's early iron formations. The study found that nitrate-reducing bacteria produced toxic nitrogen monoxide, ...

This illustrates the complex network of biogeochemical interactions that controlled life in the Earth's early oceans,” Bryce says. Reference: Nikeleit V, Mellage A, Bianchini G, et al. Inhibition of ...

Get Instant Summarized Text (Gist) A new 5+ oxidation state has been achieved for the rare earth element praseodymium, previously thought too unstable to observe.
