In living organisms today, complex molecules like RNA and DNA are constructed with the help of enzymes. So how did these molecules form before life (and enzymes) existed? Why did some molecules end up ...

Catalytic molecules can form metabolically active clusters by creating and following concentration gradients -- this is the result of a new study. Their model predicts the self-organization of ...

For decades, scientists have searched for clues to how life first emerged on Earth. Many theories focus on simple molecules reacting in water or on fragile protocells drifting in ancient seas. A new ...

Tremendous progress in the field of prebiotic chemistry has shown how simple compounds available on ancient Earth could have given rise to the molecular building blocks of life 1. The current ...
