Are fleas as interesting as whales? What is the likelihood of passing down a kidney disease? And how likely are you to be swept away by a tornado? Those are some of the questions NPR science reporter Nell Greenfieldboyce grapples with in her new book “Transient and Strange: Notes On the Science of Life.” The book includes a number of essays considering the intersection of the wonders of the universe with the personal. Greenfieldboyce has been heard pm WAMC since joining NPR in 2005.
