They’re believed to be victims of the genocide25 years ago. Over the span of just three months in 1994, more than a million people were murdered in Rwanda.

Interviews with some of those rescuers shed valuable light on the dynamics of heroism.

Journalist Christopher Carosa pieced together the true story in his book, “Hamburger Dreams” and joined us over the summer.

Scientists at the University of Illinois think plants could grow a lot bigger and faster if only photosynthesis were more efficient. So they’re trying to hack the process and at the start of this year I spoke with two of them. Amanda Cavanagh is a post-doc and Don Ort is a professor of plant biology. Their project is called Realizing Increased Photosynthetic Efficiency -or RIPE.
