Since the 2016 reports of a mysterious assault on U.S. embassy staff in Cuba, researchers have struggled to find evidence of injury or weapon. Now, new research has discovered inner-ear damage in some of the personnel complaining of symptoms. Former International News Editor Rich Stone talks to host Sarah Crespi about the case, including new reports of a similar incident in China, and what kind of weapon—if any—might have been involved.

Sarah also talks with Staff Writer Gretchen Vogel about the bones of an extinct gibbon found in a 2200- to 2300-year-old tomb in China. Although gibbons were often featured in historical poetry and paintings, these bones confirm their presence and the fact that they were distinct from today’s species.
