Living Planet Report (starts at 5:50): The environmental organization World Wildlife Fund just released its science-based biennial Living Planet Report. It doesn’t paint a rosy picture overall; WWF shows that, for instance, wildlife populations across the globe are roughly half the size they were 40 years ago. And although rich countries show a 10 percent increase in biodiversity, lower-income countries are suffering a drop of nearly 60 percent. The report also ranks the ecological footprints of 152 nations, and warns that the world is living beyond its means. But there are bright spots in the report, too. Even in the absence of national legislation and international treaties, some cities in the U.S., including Boulder, and around the world are making progress toward sustainability and greenhouse gas reductions. Co-host Susan Moran interviews Keya Chatterjee, director of WWF’s renewable energy and footprint outreach program.
Finding Exoplanet Water (starts at 18:15): For the first time, scientists have detected water vapor on a cold exoplanet the size of Neptune. Previously, it had only been possible to measure the atmospheres of larger, Jupiter-sized exoplanets, but these findings from the Hubble and Spitzer Telescopes bring scientists a significant step closer to studying the atmosphere of Earth-sized planets orbiting other stars. Understanding the atmosphere of exoplanets may tell us more about their evolution and formation – Eliza Kempton, assistant professor of physics at Grinnell College in Iowa, explains in this report from Roland Pease of the BBC’s Science In Action.

Baseball Vision (starts at 5:42): The major league baseball season is now in full “swing.” Fans may take it for granted that these professional athletes are in top physical condition. What’s less known is how important it is for baseball players to have perfect eyesight. Batters in particular have some of the best vision in the world. To find out how scientists know this, and study it, and even make it better, How on Earth’s Shelley Schlender last month headed down to spring training in Arizona. There, she caught up with two of the nation’s top experts on the science of vision, and sports.
