Checherta

OPEN CONCEPT A hut in the jungle village of Checherta has no walls and is open to the outdoors, letting environmental bacteria live inside. More urban dwellings tend to have bacteria that come from humans.

The larvae of Diamphidia nigroornata beetles produce a toxin that Ju|'hoan hunters collect for poison arrows.

HEY LOOK  The spherical bacteria Synechocystis (shown here in false color) can use their single-celled bodies almost like eyeballs. A light shining up from the bottom of this image passes through the cells and focuses on the far side (white arrows highlight examples of focused light). A laser light source in the center (red dot) helped test which way the cells move in reaction to bright spots of light.
