This week, another ode to the Gympie-Gympie Bush as we hear from a listener about new discoveries from science labs down under. We discuss Apple's announcements and the features we'd borrow for Android and why Google is tightening its internal message boards. We explain how Senators are grilling Google in the latest anti-trust hearings, and what to expect from its next hardware event. Plus, how Google is committing to a carbon-free future, and "spilled tea" involving YouTube CEO Susan Wojcicki.
