These people put a buzz in biology. On NightLife Thursday nights, the museum goes adults-only, with thumping music, crazy lights, multiple bars and table tennis. (Who knew that Berlin-style table tennis was such a big thing in the city?) You'll likely find a DJ or live band in the building's central dining area, near an exhibition of California ground squirrels. Sometimes there are spiked snow cones. Tickets are usually $12 for nonmembers. The party goes 6 to 10 p.m. Then you'll need to find another. 55 Music Concourse Drive, Golden Gate Park; (415) 379-8000, http://www.calacademy.org.
