Researchers discover that the Oriental Hornet can convert sunlight into energy. Scientists look to imitate the insect's body structure and apply it to solar technology. Wynn Tucker reports.
GELLERMAN: Coming up Â– oceanography and poetry. I think I shall never seeÂ….a poem lovely as the sea. But first, this note on emerging science from Wynn Tucker.

[SCIENCE NOTE THEME]
TUCKER: A new kind of Â‘green hornetÂ’ has caught the attention of scientists at Tel Aviv University. The Oriental Hornet can be found from the Middle East to India, and it has the ability to convert sunlight into energy. Unlike other flying insects, this hornet is most active during the middle of the day, when the sun shines the brightest. Scientists discovered that its body acts as a solar panel.
The exoskeleton of the oriental hornet is brown with a ring of yellow around its abdomen. The brown section of the exoskeleton is covered with tiny grooves that trap light. The yellow ring gets its color from a pigment called Xanthopterin, which converts the sunlight into energy.
The hornet uses this energy to build its nest. Researchers hope to apply the structure of the hornetÂ’s exoskeleton to solar panels. If this does lead to a more cost-effective solar panel, the oriental hornet could take the sting away from the high prices of solar technology.
ThatÂ’s this weekÂ’s Note on Emerging Science, IÂ’m Wynn Tucker.
