Two surprising critters living in the tiny world of moist soil

The unseen world of soil microbiota is full of surprises: Take, for instance, tiny animals called water bears that thrive in almost any location on Earth (and even outer space) through suspended animation.

That is, if all banks are run equally, they…

Wet or dry: Butterflies reverse sex roles in extreme seasons

In the case of the African butterfly Bicyclus anynana, females develop ornate wings and court males if they spend the larval stage in a dry, cool environment.
