A new study offers deeper insight into an age-old physics question: Why does petting your cat lead to a buildup of static electricity?

(Even better, the result is relevant to all friction-related static charge.)

Foam peanuts clinging to a cat's fur due to static electricity. The electric field of the charged fur causes polarization of the molecules of the foam due to electrostatic induction, resulting in a slight attraction of the light plastic pieces to the fur.

A 饝惔饝惗饝悷饝惗 (hiti) is an ancient Newah urban water feature: a stepped, sunken courtyard with waterspouts and a central pool. These are fed through a remarkable network of pipes, reservoirs, and irrigation systems drawing water from mountain springs dozens of kilometres away. Every day, hundreds of people from the neighbourhood come to draw water, bathe, and exchange news. They are a unique and precious feature of Newa urban architecture through which neighbourhoods are created.
