One student is dead and eight others are injured after a school shooting at a STEM school in Colorado, just miles from Columbine High School. Also, "Auschwitz. Not Long Ago. Not Far Away." opens Wednesday at the Museum of Jewish Heritage in New York. The exhibit, produced in partnership with Auschwitz-Birkenau State Museum in Poland, brings more than 700 artifacts to North America for the first time to tell the story of the Holocaust. And we talk to a marine biologist about basking sharks off the coast of California.
