Why a campaign has started to bring back some plants that have been forgotten

The world depends on just a few crops for most of its food. Because that dependence could be risky, a new international effort supports research and development of overlooked plants as food sources.

'Water batteries' could store solar and wind power for when it's needed

San Diego has an ambitious plan to store renewable energy, using extra solar power to pump water up a mountain. This old-style "water battery" technology could be set for a revival.

How climate change is forcing cities to rebuild stormwater systems

Deep below our city streets lie intricate networks of underground piping built to carry away excess rainfall run off. These stormwater systems mostly go unnoticed until heavy rains overwhelm them, causing streets to flood. Now, with rising rainfall averages in much of the nation, cities need to plan for more water. Guest host Dan Charles talks to climate correspondent Lauren Sommer about the challenges of such planning and why many cities aren't set up to handle the coming rains.

Placebos Vs Parkinson's: The Power Of Joy

Parkinson's disease is a brain disorder that leads to difficulty with walking, balance and coordination. There is currently no cure, but scientists in Pittsburgh, PA have an ambitious plan to develop a treatment based on the placebo effect. NPR science correspondent, Jon Hamilton, tells the story of how this plan came to be. It involves a batch of illegal drugs, the rabies virus, and figuring out what makes a monkey really happy.

The Debate About Pablo Escobar's Hippos

Pablo Escobar had a private zoo at his estate in Colombia, with zebras, giraffes, flamingoes - and four hippopotamuses. After Escobar was killed in 1993, most of the animals were relocated except for the so-called "cocaine hippos." Authorities thought they would die but they did not and now, about a hundred roam near the estate. Conservationists are trying to control their population because they worry about the people and the environment. But some locals like the hippos and a few researchers say the animals should be left alone and are filling an ecological void. The controversy reflects growing debate in ecology about what an invasive species actually is.
