After their life as research subjects, what happens to lab monkeys? Some are euthanized to complete the research, others switch to new research projects, and some retire from lab life. Should they retire in place—in the same lab under the care of the same custodians—or should they be sent to retirement home–like sanctuaries? Online News Editor David Grimm joins host Sarah Crespi to discuss recently penned legislation that pushes for monkey retirements and a new collaboration between universities and sanctuaries to create a retirement pipeline for these primates.
Sarah also talks with Dante Lauretta, principal investigator for NASA’s Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) and a professor at the University of Arizona in Tucson, about the latest news from the asteroid Bennu. Within 1 week of beginning its orbit of the asteroid, OSIRIS-REx was able to send back surprising images of the asteroid ejecting material. It’s extremely rocky surface also took researchers by surprise and forced a recalculation of the sample return portion of the craft’s mission.

Researchers are using artificial intelligence techniques to invent medicines and materials—but in the process are they upending the scientific method itself? The AI approach is a form of trial-and-error at scale, or “radical empiricism”. But does AI-driven science uncover new answers that humans cannot understand?

Who among us hasn’t wished we could read someone else’s mind, know exactly what they’re thinking? Well that’s impossible, of course, since our thoughts are, more than anything else, our own. Private, personal, unreachable. Or at least that’s what we’ve always, well, thought. 
Byer also helped develop the quietest, most stable laser in the world, called the diode-pumped YAG laser. YAG lasers are today found in everything from communications satellites to green handheld laser pointers, which Byer co-developed with two of his graduate students and cites as one of his favorite inventions (he had joined Stanford in 1969). YAG lasers also form the main beams of the gravitational wave-detecting instrument, LIGO, which in 2015 achieved the most precise measurement ever made by humans when its antenna detected the tenuous spacetime fluctuations generated by two colliding black holes 1.3 billion light-years away.
One summer morning in 1964, Byer drove the hour from Berkeley down to Mountain View for a job interview at a California company called Spectra Physics. He walked in to find an empty lobby but could hear clapping and cheering in the back of the building. After politely waiting for several minutes, he followed the commotion to a darkened room filled with men whose jubilant faces were illuminated by a rod of red-orange light that seemed to float above an instrument-strewn table
