MBL Director Nipam Patel joined the Science Friday crew to talk about one of this favorite scientific topics—butterflies. 

Scientists are learning that butterfly wings are more than just a pretty adornment. Once thought to be made up of non-living cells, new research suggests that portions of a butterfly wing are actually alive—and serve a very useful purpose.

In a study published in the journal Nature Communications, Naomi Pierce, curator of Lepidoptera at the Harvard Museum of Comparative Zoology, found that nano-structures within the wing help regulate the wing’s temperature, an important function that keeps the thin membrane from overheating in the sun. They also discovered a “wing heart” that beats a few dozen times per minute to facilitate the directional flow of insect blood or hemolymph. Read more of the article here.
