Unlocking The Secrets of Our Cells - The Nobel Prize Previous Broadcasts

KQED World: Sat, Jun 8, 2013 -- 1:00 PM

Inside all of us exists a series of micro-worlds at the cellular, molecular and atomic level, constantly working to maintain our existence, but of which we are blissfully unaware. The 2012 Nobel Laureates in Physiology or Medicine, Physics and Chemistry, have all unveiled new knowledge about this micro-world; this program explores their work, going on a journey through the micro-layers, showing how the discoveries they have made influence all our lives. Inside all of our cells is the next - molecular- level of the micro-world. The 2012 laureates in Chemistry identified and mapped the molecules that enable cells, and therefore our bodies, to react to the outside world. Robert Lefkowitz takes us through the long journey he went through to identify and map the protein responsible for transmitting outside influences into the cell so it can react - for example, in the adrenaline response in the body. He describes his and Brian Kobilka's work - and how it felt when they realized they'd made their groundbreaking discovery. The micro-world is going on all around us and, were it not for the work of this year's laureates, many of its secrets would still remain hidden.

    • Wed 11/30: planned momentary outages of DT54 over the air signal

      (this is a continuation of the work originally announced for 11/28, which was not completed on Tuesday.) At some point during the morning of Wednesday Nov. 30th, the KQEH transmitter will switch from its main antenna to the auxillary one, to allow for the safety of workers doing maintenance for another TV station on the […]

    • Tues 11/29: DT54 Over the Air Signal restored

      Repairs have been completed on today’s transmitter issue, and the signals for DT54.1 through 54.5 have been restored.

    • Tues 11/29: DT54 Over the Air signal currently down

      (DT54.1 through 54.5) During the course of the work described below, which necessitated moving our outgoing signal from the main antenna to the auxillary antenna, the transmitter suddenly shut down. As of 3:30pm Tues, we do not have an estimated time for repair and return of the Over the Air signals for DT54.1 through 54.5
