How to weigh a star—with a little help from Einstein, toxic ‘selfish genes,’ and the world’s oldest Homo sapiens fossils

Science Magazine Podcast
Released on Jun 8, 2017

This week we have stories on what body cams reveal about interactions between black drivers and U.S. police officers, the world’s oldest Homo sapiens fossils, and how modern astronomers measured the mass of a star—thanks to an old tip from Einstein—with Online News Intern Ryan Cross.

 Sarah Crespi talks to Eyal Ben-David about a pair of selfish genes—one toxin and one antidote—that have been masquerading as essential developmental genes in a nematode worm. She asks how many more so-called “essential genes” are really just self-perpetuating freeloaders?

 Science Careers Editor Rachel Bernstein is also here to talk about stress and work-life balance for researchers and science students.
