Summary
This podcast has been corrected: in a previous version at 5:55 we stated that that the team's 200mm devices currently contain only a couple of magnetic tunnelling junctions, in fact they studied 500-1000 devices in this work.
Update 15 May 2026: The paper on zebra finch songs featured in this podcast was retracted on 15 April 2026.
00:48 How mysterious skyrmions could power next-generation computers
Skyrmions are tiny whirlpools of magnetic spin that some researchers believe have useful properties that could unlock new kinds of computing. However getting skyrmions to perform useful computational tasks has been tricky. Now researchers have developed a method to create and manipulate skyrmions in a way that is compatible with existing computing technology, allowing them to read and write data at a fraction of the energy cost of conventional systems. The team think this shows that skyrmions could be a viable part of the next generation of computers.
