About this episode

In this episode:


00:47 First observation of oxygen 28

Oxygen 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.

10:06 Research Highlights

How venus fly traps can protect themselves from wildfires, and a ball-point pen that can ‘write’ LEDs.

12:39 An AI for Drone Racing

AIs have been beating humans at games for years, but in these cases the AI has always trained in exactly the same conditions in which it competes. In chess for example, the board can be simulated exactly. Now though, researchers have demonstrated an AI that can beat humans in a place where simulation can only take you so far, the real world. The Swift AI system is able to race drones against champion-level humans, and beat them most of the time. The researchers hope this research can help improve the efficiency of drones in general.
