Photochemistry podcasts

This Briefing Chat examines a tattoo ink that becomes visible under ultraviolet light and then fades, before discussing whether epigenetic changes and jumping genes help explain why larger dogs age more quickly.

Melissa and Jam examine the chemistry and cell biology proposed to explain red-light therapy. They discuss photobiomodulation, mitochondria, collagen and the limitations of available studies, alongside the distinction between regulatory clearance and evidence for a particular consumer device.

Hosted by Melissa, Jam

Mariana Kneppers, Patrick Walter and Neil Withers compare competing cathode materials for electric-vehicle batteries and the tradeoffs among cost, safety and performance. They also discuss a photocatalyst that uses spent car-battery acid to help convert plastic waste into useful chemicals.
