NOVA scienceNOW: Capturing Carbon

This video from NOVA scienceNOW explains how geophysicist Klaus Lackner and two engineers, Allen and Burton Wright, teamed up to develop a technology to capture an important greenhouse gas, carbon dioxide (CO2), in the air. Modeling their design after a tree—and one of Lackner's daughter's science experiments—the team tested different materials, configurations, and coatings that together would act as leaves do to remove CO2 from the air. However, instead of mimicking photosynthesis, their process uses a manufactured fabric that attracts CO2 and pulls it out of the air for subsequent storage.

Sea Otter Heroes: The Predators That Saved an Ecosystem

In Elkhorn Slough, an inlet on the California coast, seagrass grows healthy and strong in the shallow water, providing homes for fish, preventing erosion, and trapping carbon from the environment.

This healthy seagrass baffled marine biologist Brent Hughes. Water in the slough is chock-full of nutrients from fertilizer runoff on nearby farms. Normally, nutrient-polluted water supports huge population of algae that block sunlight from reaching the seagrass, and the seagrass dies. Why has the slough's seagrass thriving?
