The introduction and concentration of electron donors and acceptors in the subsurface biosphere is controlled by the mixing of subsurface fluids, but the mechanisms and rates at which microbial communities respond to changes induced by fluid mixing and transport are relatively unknown.

They live several kilometers under the surface of the earth, need no light or oxygen and can only be seen in a microscope.

An international team of scientists recently returned from a 47-day research expedition to the middle of the Atlantic Ocean have collected an unprecedented sequence of rock samples from the shallow mantle of the ocean crust that bear signs of life, unique carbon cycling, and ocean crust movement.

Around 720-640 million years ago, much of the Earth's surface was covered in ice during a glaciation that lasted millions of years.

Planet Earth is situated in what astronomers call the Goldilocks Zone -- a sweet spot in a solar system where a planet's surface temperature is neither too hot nor too cold.

Recent research which has counted with the participation of the University of Granada Andalusian Institute of Earth Sciences has yielded new data on chemical gardens, mysterious formations produced when certain solid salts (copper sulfate, cobalt chloride) are added to an aqueous solution of sodium silicate.

According to new research humble, microscopic organisms can create dripstones in caves. This illustrates how biological life can influence the formation of Earth's geology - and the same may be happening right now on other planets in space.

Scientists have discovered that the earliest living organisms on Earth were capable of making a mineral that may be found on Mars.

The chemical reactions behind the formation of common metabolites in modern organisms could have formed spontaneously in the earth's early oceans, questioning the events thought to have led to the origin of life.

Researchers from the University of Cambridge have published details about how the first organisms on Earth could have become metabolically active.
