A new study explores how complex chemical mixtures change under shifting environmental conditions, shedding light on the prebiotic processes that may have led to life. By exposing organic molecules to ...

Simple systems can reproduce faster than complex ones. So, how can the complexity of life have arisen from simple chemical beginnings? Starting with a simple system of self-replicating fibers, ...

To create A1 lipid nanoparticles for delivering mRNA to target cells, scientists at the University of Pennsylvania used A3 coupling. A3 refers to the amine–aldehyde–alkyne coupling reaction, which the ...

An outtake from a mural on the origin of life celebrates famous experimental milestones in the science that tries to explain how chemicals evolved into the first building blocks of life on an Earth ...

The stars in our galaxy exhibit a curious chemical division, but is this the norm in the Universe? A recent study shows that this peculiarity is not a general rule, opening the door to a ...
