Freezing with Sound: How Thermoacoustic Cooling Works

Breakthrough Broadcast ·

2025/12/06

Thermoacoustic cooling sounds like science fiction at first glance. Cooling something with sound feels almost unreal, yet the physics behind it is solid and surprisingly elegant. In this episode of Breakthrough Broadcast, Drew takes listeners inside a technology that replaces chemical refrigerants with nothing more than sound waves, carefully shaped tubes, and a clever understanding of how heat moves through air. The story begins with the strange early experiments that hinted at this effect long

The Problem with Hypersonic Speed: Solving Plasma at...

Breakthrough Broadcast ·

2025/11/08

In this episode of Breakthrough Broadcast, Drew takes a close look at what happens when planes fly faster than sound and why plasma becomes one of the biggest challenges at those speeds. At Mach 5 and beyond, the air around an aircraft heats up so much that it turns into a glowing field of charged particles. That plasma blocks radio signals, scrambles sensors, and makes communication almost impossible. Drew explores how engineers and physicists are trying to solve this problem through new materials,

Thoughts to Things: Building a Bridge to the Brain

Breakthrough Broadcast ·

2025/11/01

This episode explores the rapidly advancing world of brain–computer interfaces (BCIs), or “brain chips.” These devices connect the human brain directly to computers, allowing thoughts to control external systems like robotic arms or cursors. Drew explains that every thought and movement comes from tiny electrical signals between neurons, which brain chips detect and decode using electrode arrays and machine learning. Some even send signals back to the brain, restoring sensations such as touch.The

Spintronics: Computing With the Hidden Side of Electrons

Breakthrough Broadcast ·

2025/10/04

Spintronics is a field that sounds futuristic, but it is already shaping the way scientists and engineers think about electronics. Instead of relying only on the movement of electrons for power, spintronics makes use of another property: the spin of the electron. This small quantum trait can be harnessed to store and process information in ways that are faster, smaller, and far more energy-efficient than today’s silicon-based systems. In this episode, we dive into how spintronics works at a
