A new study used mathematical formulas and demonstrated that it’s highly unlikely life began on Earth. Instead, the ...

For decades, chemistry students have learned a simple truth: polar and nonpolar substances don’t mix. Water and oil stay ...

New research has found that amino acids, the building blocks of life, may have traveled to Earth on interstellar dust grains, ...

Think of it this way: only around 10,000 decently sized meteorites slam into Earth per year. Meanwhile, the planet is ...

The question of when life began on Earth is as old as human culture. “It’s one of these fundamental human questions: When did life appear on Earth?” said Professor Martin Whitehouse of the Swedish ...

From a distance, Biosphere 2 emerges from the cacti and creosote of the Sonoran desert like a gleaming oasis, a colony of glass and bright white structures. Despite being just outside Tucson, Arizona, ...

Chemists at University College London have shown how two of biology's most fundamental ingredients, RNA (ribonucleic acid) and amino acids, could have spontaneously joined together at the origin of ...

All life on Earth can be traced back to a Last Universal Common Ancestor, or LUCA. A study suggests that this organism likely lived on Earth only 400 million years after its formation. Further ...
