This week, in honor of Valentine's Day, we're presenting two stories about heartbreak in science. Part 1: Rattled by a recent heartbreak, neuroscientist Prabarna Ganguly makes a mistake in the lab. Part 2: Marine ecologist Kirsten Grorud-Colvert bonds with her diving buddy when they have an unexpected encounter with a hammerhead shark.  Prabarna Ganguly is one of the many Bostonian graduate students, studying neuroscience at Northeastern University. Her research focuses on how and why maternal care is necessary for the healthy development of infants. As an aspiring science writer, she is constantly looking for good science stories to share, and makes sure that her elevator pitches are always grandma-friendly. Comfortably Indian, she likes cricket, Pink Floyd, and enjoys simple frivolities. Also, having just dyed her hair red, she is quite excited about its possibilities.   Note: Kirsten's story was produced as part of our partnership with Springer Nature's Springer Storytellers program.

Kirsten Grorud-Colvert is a marine ecologist at Oregon State University, where she has studied ocean organisms in the Oregon nearshore, the Florida Keys, and California’s Catalina Island, along with other marine systems from the Mediterranean to the Caribbean. She uses data from different species and habitats to ask, What happens when you protect an area in the ocean? And what can we learn from those areas to design even better protection? She also directs the Science of Marine Reserves Project and loves learning from her creative colleagues in science, communication, and graphic design. Kirsten has always been obsessed with water—that’s what growing up in the 120 degrees Arizona desert will do to you!  Learn more about your ad choices. Visit megaphone.fm/adchoices
