In this episode:00:47 First observation of oxygen 28Oxygen 28 is an isotope of oxygen with 20 neutrons and eight protons. This strange isotope has long been sought after by physicists, as its proposed unusual properties would allow them to put their theories of how atomic nuclei work to the test. Now, after decades of experiments physicists believe they have observed oxygen 28. The observations are at odds with theory predictions, so they imply that there’s a lot more physicists don’t know about the forces that hold atomic nuclei together.Research article: Kondo et al.News and Views: Heaviest oxygen isotope is found to be unbound10:06 Research HighlightsHow venus fly traps can protect themselves from wildfires, and a ball-point pen that can ‘write’ LEDs.Research Highlight: Venus flytraps shut their traps when flames approachResearch Highlight: A rainbow of LEDs adorns objects at the stroke of a pen12:39 An AI for Drone RacingAIs have been beating humans at games for years, but in these cases the AI has always
