mother nature
Apoica is a genus of eusocial paper wasps found throughout the Central and South American tropics. These wasps are truly nocturnal,
carrying out their foraging activities after the setting of the sun.
They prefer to construct their nests, which have an open comb like many
paper wasps, under large leaves, or in shrubs. During the day, wasps
covering the comb fan their wings to cool the nest, keeping it at a
suitable temperature for larval development. When attacking prey, Apoica release a drop of venom from their stings, which in turn attracts any nearby wasps to attack.

The Writer
Cambridge’s Professor Simon Schaffer presents The Writer, a
240-year-old, 6000 piece machine that was created by Swiss-born
watchmaker Pierre Jaquet-Droz, his son Henri-Louis, and Jean-Frédéric Leschot around 1770-1772.
The automaton can be programmed up to 40 letters or signs, and lives at the Musée d’Art et d’Histoire in Switzerland with two other of Jaquet-Droz’s automata: the drawer and the musician.
