The mystery of why life uses molecules with specific orientations has deepened with a discovery that RNA—a key molecule thought to have potentially held the instructions for life before DNA ...
There are key moments in Earth's history that remain shrouded in mystery. The emergence of the first molecules capable of working together to give rise to life is one of them. For several decades, ...
A breakthrough experiment, published in the Proceedings of the National Academy of Sciences, offers compelling support for the RNA world hypothesis, one of the leading theories on how life began on ...
How life began on Earth has captivated scientists for centuries. A prevailing theory in the scientific community, known as the “RNA World” hypothesis, suggests life might have originally come from ...
A new method can test the activity of thousands of RNA enzymes, called ribozymes, in a single experiment. The "RNA world" hypothesis proposes that the earliest life on Earth may have been based on RNA ...
The transition from simple chemistry to the complex biology of molecules that gave rise to life is a puzzle that scientists have been trying to solve for ages. A new study suggests that conditions on ...
