Episode 335

Exercise has been shown to shrink tumours by 60 per cent. A new study shows another link between regular exercise and cancer prevention, this time revealing that muscle cells may outcompete cancer cells for energy - basically starving them. We explore the links between metabolism and glucose - with the caveat that so far this has only been demonstrated in mice, in a small study.

The interstellar object 3I/ATLAS may be even weirder than we thought. Ever since we spotted this comet from another star system, scientists have been studying every inch of it. And no - it’s not an alien spacecraft. But it does seem to be home to surprising amounts of chemicals like carbon dioxide and methanol - essential ingredients for life. Could this shed light on the origin of life in the universe?

A 100-year-old debate between two titans of physics has finally been settled. In the 1920s, Albert Einstein and Niels Bohr butted heads about the nature of light. Einstein said light is a particle. Bohr said it’s both a particle and a wave. They came up with an experiment to settle the argument - the trouble is, they had no way to run it. Now, 100 years later, we finally have the technology to perform the test - and the winner is…

Hosted by Rowan Hooper and Penny Sarchet, with guests Alexandra Thompson, Alex Wilkins and Jacob Aron.
