Growing Coral

According to a 2017 study by the UN, coral reefs may cease to exist by the end of the century. In an effort to save these vital ecosystems, biologists at the Georgia Aquarium in Atlanta are growing coral in labs. Our partner Science Friday has the story.

Photosynthesis and Clean Energy

Scientists have used artificial photosynthesis to generate clean energy. This process typically requires electricity or natural gas but now researchers have developed a new device that’s more than twice as efficient and runs only on water and sunlight. Zetian Mi, professor of Electrical Engineering and Computer Science at the University of Michigan in Ann Arbor joins Hari […]

Climate change and our waterways

Most people assume the water they are drinking is safe and protected by government regulations. However, one community in Central New York is learning that even the most pristine of lakes can fall prey to the effects of climate change. This segment is part of Peril and Promise, our ongoing series of reports on the […]

Farmers are using an ancient technique to purify water

Like the ancient Amazonians of centuries past, farming companies today are using a carbon-rich material to enhance soils or purify polluted waste water. It’s called “biochar.” We take you to Florida, where farmers and geochemists are creating biochar through an age-old practice.

SciTech Now Episode 240

In this episode of SciTech Now, how farming companies are using a carbon rich material to enhance soils and purify waste water; can the Japanese art of paper folding, known as “origami,” save lives?; using apps to improve the lives of low-income Americans; and a look at innovative robotic technology being developed in Tokyo.

Desalination making water safer and cleaner

One of our most precious resources—fresh and clean drinking water—is in short supply. The largest desalination plant in North America, located near Tampa, Florida, uses reverse osmosis to create safe, clean, and much needed water for a thirsty public.
