See a Billion-Year Dance of Earth’s Tectonic Plates in 40 Seconds, offers Singularity Hub –The beauty of science is how far it extends our view into space and time. We now know the sun and stars whip around the center of our galaxy just as the Earth orbits the sun.

How Vulnerable Is Planet Earth asks Oxford philosopher Nick Bostrom and Matthew van der Merwe for Aeon –“Sooner or later a technology capable of wiping out human civilization might be invented. How far would we go to stop it? …We call this ‘the vulnerable world hypothesis’.

Why COVID-19 Models Don’t Predict the Future, reports Jordana Cepelewicz for Quanta–To understand what epidemiological models can tell us, it helps to first understand what they can’t. In the fight against COVID-19, disease modelers have struggled against misunderstanding and misuse of their work. They have also come to realize how unready the state of modeling was for this pandemic. “For a few months last year, Nigel Goldenfeld and Sergei Maslov, a pair of physicists at the University of Illinois, Urbana-Champaign, were unlikely celebrities in their state’s COVID-19 pandemic response — that is, until everything went wrong.”

Why Did It Take Dinosaurs 15 Million Years To Reach The Northern Hemisphere? asks Scientific Blogging.–In the age of the dinosaurs, you could have walked from one pole to another. At that time, the continents were all joined together, forming the supercontinent Pangea. Yet they didn’t.
