In December, Public Laboratory members made themselves a "public lavatory." Six members of the online DIY science community gathered in the well-appointed, but small bathroom of staff member Liz Barry with the lights off -- for citizen science. Two staff members (Leif Percifield and Jeff Warren) stood in the bathtub lofting a laptop so the webcam pointed downward to capture the scene. Another (Chris Eichler) perched precariously on the sink with a camera, snapping photos of the path of light on the wall cast by the newest research tool -- a thermal flashlight.

In September, members of Public Laboratory for Open Technology and Science (PLOTS) met with residents of Garfield County, Colo., to discuss the growing hydrogen sulfide problem in their small, rural community. Public Laboratory is an organization and membership community which develops and applies open-source tools to environmental exploration and investigation. Hydrogen sulfide, a neurotoxic and potentially lethal gas, can be produced by bacteria growing in natural gas wells, or can natively occur within reserves of natural gas. Natural gas development is booming across North America, and with it, cases of hydrogen sulfide poisoning...
