Hosted by Lester Nare and Krishna Choudhary, this story explores how scientists in Korea are harnessing the overlooked property of electrons — their spin — to build ultra–low-power devices. By flipping the script and treating energy loss as a feature rather than a flaw, researchers are pushing the frontier of spintronics and opening new doors for AI, data, and computing efficiency.

Summary

• Politicians spin news, scientists spin electrons
• Korea’s breakthrough: turning spin loss into usable energy
• Spintronics explained: using both electron charge and spin
• Moore’s Law slowdown and the Von Neumann bottleneck
• Early success: giant magnetoresistance and Nobel-winning hard disks
• New approach: using dissipation as a functional component
• Why this could reshape computing and AI’s energy demands
• Commercial viability: compatible with existing chip infrastructure
•
