From Ebola to hantavirus, ecological disruptions are creating the conditions for more frequent and dangerous spillover events. Researchers say interdisciplinary collaboration and investment in early surveillance is essential to prevent and respond to these threats.

Brief pulses of electrical current can dramatically extend the lives of sea squirts, whose rapid stem cell regeneration and simple immune systems make them a useful analog for understanding aging in humans. The findings point toward new strategies for protecting species from environmental shifts, and mitigating age-related decline.
