Please note: The Academy is temporarily closed, effective Sunday, November 29, 2020.
Members, it was wonderful to reunite with you in October and November, but San Francisco's downgrade into the "purple" tier requires us to close our doors to protect public health. We continue to be grateful for your unflagging support during this difficult year, and look forward to welcoming you back once again when it's safe to do so.
For more information, please visit our closure page.

Academy scientists added 213 new species to the tree of life this year. Meet some of the standouts, from dazzling nudibranchs to a "slingshot predator" preserved in amber.
