Patching holes in broken hearts

Solving the mysteries of Earth’s Cryogenian ice age
Typically, one wouldn’t think to ask a geologist about the most pressing issues in evolutionary biology.

Rapid urbanization is driving biodiversity decline
Humanity is currently experiencing an unprecedented era of urban growth.
