Life’s First Blueprint Wasn’t DNA; it was RNA.

Read Jacob Fine’s latest publication here: https://www.sciencedirect.com/science/article/pii/S0022283625001901

Today we spoke with Jacob Fine, graduate student researcher in Computational Biology from the University of Toronto. We explore the physics of replication, the role of entropy and information theory, and how modern biology is reconnecting with theory to understand the most fundamental question in science. Our conversation takes place in a Russian sauna, where the hot and humid environment mimics some of the conditions needed for life to begin.

One of Keith Johnson’s final interviews: a brilliant mind on dark matter, water, and fusion.

Read about Keith’s legacy here: https://news.mit.edu/2025/keith-johnson-materials-scientist-independent-filmmaker-dies-0723

This episode is one of the final recorded conversations with MIT physicist Keith Johnson, who passed away just weeks after our interview. In this conversation, he unpacks his early research on the quantum structure of matter, his cold fusion theories, and how it all led to a screenplay about a young female physicist. Johnson also suggests a radical idea: water clusters in space might explain some aspects of dark matter. A one-of-a-kind interview that blends science, art, and speculation.

We’re honored to share this glimpse into Keith’s remarkable intellect, creativity, and curiosity. May his legacy continue to inspire.

Did the Big Bang really happen? Telescopes, dark matter & cosmic origins explored.

Join cosmologist Brian Keating as we explore the mysteries of the universe, from building telescopes at the South Pole to measuring the polarization of the cosmic microwave background and chasing signs of gravitational waves. We discuss Galileo’s influence, cosmic inflation, and how the Nobel Prize could be changed to better reflect the way we do science.
