Hosts:\xa0Ed Brown, Penny Dumsday, Dr. Shayne Joseph, Lucas Randall and Belinda Nicholson.

Topics covered:

Belinda tells us a bit about working at the Gemini South Observatory in Chile, and the possible cancellation of the James Webb Space Telescope. We talk about Pluto's new moon, the mouse that stole a poison-resistance gene from another species, and the mouse that runs a lot more because it's missing a gene. A high school class DNA-tested lots of tea and found some surprising extras.

And while talking about that last story, something happened. Not sure what, but the recording stopped abruptly and we never realised. We talked a lot about a how the mass-extinction event that happened right before the dinosaurs started to rule the world, probably happened a lot quicker than previously thought. Ed gives a summary of the study at the end, and links to the story can be found on our website.

Belinda Nicholson is an astrophysicist and Masters of Science student at Melbourne University.
