Bench Talk | Lasers from Peacocks! - Sex Reversal in Birds - Innovative Glass Recycling | Sept 22, 2025

Recently, physicists learned how to generate lasers from Peacock feathers. After discussing that, we explore a recent report that 5% of birds in Australia might exhibit 'sex reversal'. In 'sex reversal' the body's sex organs don't match the sex as determined by DNA testing. Finally, Dr. Leslie Moise reads a poem she wrote about an innovative recycling program in New Orleans that converts discarded glass bottles into beach sand. ‘Bench Talk: The Week in Science’ is a weekly program that airs on WFMP Louisville FORward Radio 106.5 FM (forwardradio.org) every Monday at 7:30 pm, Tuesday at 11:30 am, and Wednesday at 7:30 am.
