Engineers from the University of Cincinnati devise a foam that captures energy and removes excess carbon dioxide from the air — thanks to semi-tropical frogs.By: Wendy Beckman.

For decades, farmers have been trying to find ways to get more energy out of the sun.

In natural photosynthesis, plants take in solar energy and carbon dioxide and then convert it to oxygen and sugars. The oxygen is released to the air and the sugars are dispersed throughout the plant — like that sweet corn we look for in the summer. Unfortunately, the allocation of light energy into products we use is not as efficient as we would like. Now engineering researchers at the University of Cincinnati are doing something about that.
