Thrown from supernovae, silicon is the eighth most abundant element in the universe and second only to oxygen in the Earth’s crust, which is primarily comprised of silicate compounds, including silica (SiO2), or quartz, commonly found in sand. Silica is absorbed by plants and transformed into intricate glass shells by radiolarians and other microscopic marine creatures. Humans, for their part, have worked silica into glass, ceramics, and devices such as phonograph pickups and crystal oscillators for clocks.

A dozen whales, different species and ages, have washed up recently on nearly 300 miles of Northern California coastline. While this is not a record, it's still alarming. Why is it happening? Bay Area scientists are considering factors such as environmental changes, food distribution, shipping, ocean currents, and predator behavior. Meet staff from the California Academy of Sciences, Mission Science Workshop, and the Exploratorium, and explore evidence leading to and hypotheses about these tragic events.

The Ebola virus has spread from West Africa to the United States with three confirmed cases and one death. The outbreak is generating fear, airport screenings, and a storm of media coverage. But how worried should we really be? Get the facts about Ebola from UCSF physician and infectious disease researcher Charles Chiu, who studies the Ebola virus and how it spreads.

Join us for a live chat with researchers aboard the Exploration Vessel Nautilus as they study an active volcano beneath the Caribbean Sea. We'll ask them how ocean exploration has changed with the introduction of high-bandwidth satellite communications that allow scientists on shore to join the expedition virtually.

Join us for a live chat with artist Lily Simonson aboard the Exploration Vessel Nautilus, which is studying an active volcano beneath the Caribbean Sea. A painter and educator from Los Angeles, Simonson is fascinated by the otherworldly animals of the deep sea, especially those that live around the superheated waters gushing from cracks on undersea volcanoes. She’ll tell us what it's like for an artist to collaborate with scientists at sea and what strange invertebrates she hopes to document.
