The building blocks of life on Earth may have been fueled by tiny sparks hopping between water droplets.

This water, now over 4.5 billion years old, has been perpetually renewed through Earth's water cycle. My research team has recently proposed a new theory to explain how water first arrived on Earth.

Study discovered that tiny electrical sparks, called microlightning, form when water droplets collide. These can create ...

The mantle transition zone (MTZ), which occurs 410–670 kilometers below Earth's surface, may store several oceans' worth of water. This water, which is carried to such depths by subducting tectonic ...

Life may not have begun with a dramatic lightning strike into the ocean but from many smaller "microlightning" exchanges ...

"On early Earth, there were water sprays all over the place -- into crevices or against rocks, and they can accumulate and create this chemical reaction," Zare said. "I think this overcomes many ...

A new study adds another angle to the much-disputed Miller-Urey hypothesis, which argues that life on the planet emerged from ...
