Editor's note

Activists are rallying around the world today under the banner #RiseforClimate, calling on officials to curb fossil fuel use and fight climate change. On U.S. college campuses, many students and faculty want their schools to divest from fossil fuel companies – but administrators are wary. As sustainability scholar Jennie Stephens explains, divestment debates raise hard questions for higher education leaders about their institutions’ social roles.

Cystic fibrosis is a progressive, potentially deadly, inherited disease characterized by thick, sticky mucus, especially in the lungs. It is the most common genetic disease in Caucasians, affecting 30,000 in the U.S. But more than 10 million Americans are carriers – with one copy of the cystic fibrosis mutation. Now Phil Farrell and an international team of scientists have discovered the origin of the most common mutation and the mysterious folks who may have spread it around.

On Saturday, Serena Williams will compete in the Women’s final of the U.S. Open. Throughout the tournament, she hasn’t been wearing her controversial “catsuit,” which, according to the president of the French Tennis Federation, won’t be permitted at next year’s French Open. To University of Nevada, Las Vegas fashion historian Deirdre Clemente, the hoopla over Williams’ catsuit brings to mind the old debate over whether women could wear shorts in public.
