Brainvax and the Fungus That Makes Cicadas Signal Like Females

Why it surfaced

Brainvax gives readers one story and two possible origins, then asks what earns their trust rather than what they already remember. Its second dose examines a fungus that destroys cicadas’ genitalia while infected males remain active and begin answering male songs with a female-specific signal.

A daily real-or-synthetic game built around strange, documented stories about biology and behavior.
