bio-, from Greek bios, life.
Everyone knows bio- in the context of biology and biochemistry, but it is also the root of biopsy, bionic, biography, and biopic.
ephemera, plural of ephemeron.
1. something transitory, lasting a brief time. The original Greek ephemeros implies a duration of a mere day.
2. a member of an order of winged insects (Ephemeroptera), including mayflies, with adult lifespans of hours to days.
3. written or printed matter with a short intended lifetime, often preserved by accident; including ads, lithographs, photographs, postage stamps, programs, labels. . . “ephemera” is a little hard to pin down. The word can also describe a record of brief occurrences, like a diary or almanac.
