HISTORY: As part of the SF Museum and Historical Society's 2009 "Neighborhoods of San Francisco" program, author and historian Woody LaBounty will reintroduce the community to Beachside Bohemia: Carville-by-the-Sea and the Birth of the Outer Sunset District, which he researched extensively for his new book, Carville-by-the-Sea: San Francisco’s Streetcar Suburb. Carville-by-the-Sea, which was in its heyday in the 1890s, is one of the quirkiest and least-remembered communities in San Francisco’s history. There will also be a companion walk to this event with Woody LaBounty on Saturday from 2 to 4. Meet at the corner of La Playa and Lincoln Way.

SCIENCE: This month's Ask a Scientist explores Biological Invasion!, the impact of humans' ability to swiftly travel throughout the world, as we carry plants, bugs, and diseases that have been trapped on separate continents for millions of years. Topics such as human pandemics and invasive plants will be discussed, and solutions and recent efforts to fix the problems will also be addressed.
