This week, mayflies flooded the midwest in apocalyptic numbers. This video, which shows a clutch of bebe mayflies hatching from their eggs minutes after they were laid, helps explain why.
Biology student and photographer Daniel Stoupin takes animals — some of them so tiny they can't be detected with the naked eye — and fires up his microscopes so that they get the extreme close-up they deserve.
Clearly, this is a map of the Midwest. But what exactly is it showing us? Localized population densities? A hellmouth opening just south of La Crosse? Warning: The real answer might bug you out.
