Episode 330 - A cells journey, from birth to death

This week we dive into the complicated history of cells and try to figure out if you are still the same ship. How does a cell know what it wants to grow up to be? What helps it make the decision to be an optic nerve, a neuron or part of your jawbone? How old are all the cells in your body? Are they all the same age, and what does age even mean anyway? This week we dive into the complicated history of cells and try to figure out if you are still the same ship.

Episode 329 - Mysteries from the formation of our solar systems

There are many things we don't understand from the formation of our solar system. Why did Jupiter end up with weird asymmetrical groupings of asteroids around it? Is there a region of dust free space around the sun? If there is why can't we find it? What caused the beautiful rings of dust millions of kms wide around Venus and Mercury? Where did that dust come from? All these questions and more as we unpack the hidden parts of our solar system.
