The AAAS Pacific Division will convene in San Diego from 12-16 June for an annual meeting that will range broadly across the sciences and arts—including, this year, a focus on mummies.

The division’s 92nd annual meeting will feature symposia that explore tsunamis and storm surges; the changing dynamics of Antarctic ice; a syndrome associated with autism and mental retardation; and the intersection of science with music, literature, and poetry.
