Combined structures of fatty acids and oligomers that may form cell-like compartments

Cooperation between simple molecules may explain how the first cells formed

  • No comments
Researchers at the Hebrew University of Jerusalem have linked fatty acids to hydroxy acids, resulting in membrane-like structures that assemble easily and survive longer in water. The findings suggest a possible mechanism for the transition from dormant chemistry to pre-living systems.

Life from motion: New discovery reveals how order is born from rotation

  • No comments
Tel Aviv University researchers have discovered that particles spinning in opposite directions in a liquid self-organize into polymer-like “active” chains that move, rotate, and exchange “partners” — a phenomenon that may shed light on self-organization processes in nature and lead to
