An aurora powered telegraph messages

During the 1859 Carrington Event, geomagnetically induced current disrupted telegraph systems. Yet two operators sent messages for about two hours with their batteries disconnected, using current from the aurora as their power source.

Deep underwater, enormous water pressure can stop steam and volcanic gases from expanding as violently as they do on land. Because of this, even a large eruption on the seafloor may cause little obvious disturbance at the ocean surface.

A parasitic fungus makes ants climb and bite leaves before dying

Certain Ophiocordyceps fungi infect ants and alter their behavior. An infected ant may climb vegetation and clamp its jaws onto a leaf or stem, positioning its body where the fungus can grow and release spores. The fungus effectively manipulates the host's final movements to improve its own chances of reproduction.
