The origin of the first living molecules on our planet has long been debated. However, recent experiments are revealing new ...

In an investigation to find out what sparked life on Earth, researchers have discovered that RNA formed through surprisingly ...

Grab-and-go missions to asteroids have provided some of the most scientifically valuable samples since the Apollo ...

About 700 million years ago, enormous glaciers flowed across the Earth's surface in powerful frozen rivers like "giant ice bulldozers" that pulverized our planet's crust and may have contributed to ...

A giant impact on the early Earth could have brought the building blocks of RNA to our planet, which new research suggests ...

How did life begin on Earth? While scientists have theories, they don't yet fully understand the precise chemical steps that ...

New research shows how RNA, a key molecule for life, may have formed on early Earth using simple chemistry and materials delivered by asteroid impacts, linking space science with the origins of life ...

Between a rock and a green place: Michelle Gehringer studies fossilized life on early Earth to learn more about the evolution of (oxygenic) photosynthesis - the process that makes the oxygen we breath ...

Introduction : The coherence of history / Stephen Jay Gould -- The planetary setting of prebiotic evolution / Sherwood Chang -- Early environments : constraints and opportunities for early evolution / ...

A new study explores how complex chemical mixtures change under shifting environmental conditions, shedding light on the prebiotic processes that may have led to life. By exposing organic molecules to ...

Evidence is mounting that the same basic chemistry that made Earth habitable is unfolding, or once unfolded, on Mars. From ...
