In 2006, Helen Amanda Fricker was sitting at her desk studying new satellite data when she made a starting discovery – a set of active lakes that exist underneath the ice in Antarctica. Join Helen, a 25-year veteran of Antarctic ice sheet research, and learn about the discovery, exploration and drilling of these mysterious phenomena at the southern reaches of our planet.

Conversations host Harry Kreisler welcomes Sherry Turkle, Abby Rockefeller Mauzé Professor of the Social Studies of Science and Technology at MIT for a discussion of her intellectual odyssey. In the conversation topics covered included her formative experiences, her education, and the evolution of her thinking about the impact of the objects of the cyber world--computers, internet, cell phones, and robots--on the essential elements of identity formation--solitude, conversation, and empathy.

California reached its goal of reducing emissions to 1990 levels four years ahead of the 2020 target date. Robert Epstein, co-founder of Environmental Entrepreneurs, takes a look at what is and is not working as we plan for an additional 40% reduction by 2030. He also examines California's role in reducing worldwide emissions in both developing and developed countries. Series: "UC Public Policy Channel" [Show ID: 34463]

CalSol, the UC Berkeley solar vehicle team, has been around since 1990. Over the years the team has created eight generations of solar vehicles, each one getting closer to being ready for you. They have tested out at 80 mph, although generally they go in the 40-mph range after a charge of between four and five hours. The CalSol team designs, builds and tests these cars, including the current standard bearer, Zephyr. Series: "UC Berkeley News" [Show ID: 34483]

A new fly-through of the fly brain allows anyone to whizz past neurons and visit any of the 40 million synapses where neurons touch neuron. Its a super-resolution view of the complex network connections in the insects brain that underlie behaviors ranging from feeding to mating.

Whats unprecedented, however, is that this 3D map over the whole fly brain, which shows details as small as 60 nanometers across, was captured in less than three days.

While the level of detail is not quite as good as that obtained with an electron microscope, efforts to fully map the neurons and synapses of the fly brain with EM have taken 10 years and the efforts of dozens of people. The new map was obtained a thousand times faster by combining two state-of-the-art techniques, expansion microscopy and lattice light-sheet microscopy. Series: "UC Berkeley News" [Show ID: 34478]
