Teaching robots to smile, and the effects of a rare mandolin on a scientist’s career

Science Magazine Podcast

Robots that can smile in synchrony with people, and what ends up in the letters section

First on this week’s show, a robot that can predict your smile. Hod Lipson, a roboticist and professor at Columbia University, joins host Sarah Crespi to discuss how mirrors can help robots learn to make facial expressions and eventually improve robot nonverbal communication.

Next, we have Margaret Handley, a professor in the department of epidemiology and biostatistics and medicine at the University of California San Francisco. She shares a letter she wrote to Science about how her past, her family, and a rare instrument relate to her current career focus on public health and homelessness. Letters Editor Jennifer Sills also weighs in with the kinds of letters people write into the magazine.
