Scientists have found tiny spikes on cicada wings that rupture and kill bacterial cells — a disease-fighting strategy that might also work in manmade materials.

Zoanthids, like all of the animals we typically call “coral” in the marine aquarium hobby, are cnidarians (pronounced “nigh-dare-ee-yans”). More specifically, zoanthids are part of the class Anthozoa, which includes the soft and leather corals, sea anemones, mushroom corals and stony corals (and exclude other cnidarians such as fire corals, lace corals, jellyfishes, and sea wasps). Anthozoa, as a word, originates from Greek (“anthos” and “zoion”) and translates roughly as “flower animal,” which is an apt name for most zoanthids.
Like sea anemones, mushroom corals and stony corals, zoanthids are called hexacorals because they have polyps with tentacles in multiples of six (octocorals, on the other hand, have eight tentacles). Zoanthids, unlike the “true” or stony corals (what hobbyists generally term SPS and LPS) lack skeletons, but they are also not soft corals (which are all octocorals). The polyps of zoanthids are either solitary or embedded in so-called mats. Solitary polyps are often connected to other polyps by runners (called stolons, pronounced “stoe-lahn”), while mat polyps embed themselves in a tissue matrix or mat (called a coenenchyme and pronounced “see-nehn-kyme”).

“In the game of life and evolution there are three players at the table: human beings, nature, and machines. I am firmly on the side of nature. But nature, I suspect, is on the side of machines.”
