00:07:54 Astrophysicists from the University of Florida and Columbia University have figured out that a violent collision of two neutron stars released many of the heavier atoms that went on to form our solar system.

00:13:04 The idea that glass is a liquid that flows is largely a myth.... sort of. It's an amorphous solid, so it does flow but very very slowly. Now an analysis of amber has shed some light on the disordered molecules that make glass a "liquid in suspended animation".
00:26:36 When our fishy ancestors slithered onto land nearly 400 million years ago, they had hands and feet. But fingers and toes took a little longer to develop. The discovery of a complete skeleton of a fish from around that time gives some clues about the evolution of fingers.

Dr. Helen Maynard-Casely is a planetary scientist working at ANSTO, Australia’s Nuclear Science and Technology Organisation. She is the co-author of the children's book I Love Pluto.

00:00:35 Professor Maria Croyle from the University of Texas in Austin has been working on alternative delivery mechanisms for vaccines without giant needles. And one promising method she's developed is a lot more palatable!
00:08:15 The formation of our moon is something of a mystery to astronomers. But now new research into the moon's composition further strengthens the most widely accepted theory.
This episode contains traces of the SARS-COV-2 virus translated into "surprisingly beautiful" music.
