New study challenges old views about evolution of early life
A research team led by biogeochemists at the University of California, Riverside has tested a popular hypothesis in paleo-ocean chemistry, and proved it false.

If a liquid metal alloy is cooled slowly it will eventually form a solid phase. Before it solidifies, however, the liquid undergoes a liquid-liquid transition to a phase in which it has the same concentration but a more ...
