Did plate tectonics set the stage for life on Earth?

A new study suggests that rapid cooling within the Earth's mantle through plate tectonics played a major role in the development of the first life forms, which in turn led to the oxygenation of the Earth's atmosphere. The ...

Metal-poor stars are more life-friendly, suggests study

Stars that contain comparatively large amounts of heavy elements provide less favorable conditions for the emergence of complex life than metal-poor stars, as scientists from the Max Planck Institutes for Solar System Research ...

A genetic change for achieving a long and healthy life

Living a long, healthy life is everyone's wish, but it is not an easy one to achieve. Many aging studies are developing strategies to increase health spans, the period of life spent with good health, without chronic diseases ...

The search for molecular oxygen among cosmic oxygen atoms

Oxygen is the third most abundant element in the universe (after hydrogen and helium) and of course it is important: all known life forms require liquid water and its oxygen content. For over thirty years, astronomers have ...

A microbe's membrane helps it survive extreme environments

Within harsh environments like hot springs, volcanic craters and deep-sea hydrothermal vents – uninhabitable by most life forms – microscopic organisms are thriving. How? It's all in how they wrap themselves.

'Snowball earth' might be slushy

Imagine a world without liquid water—just solid ice in all directions. It would certainly not be a place that most life forms would like to live.
