David Broomhead University of Manchester Reaction and Diffusion on Fractal Sets on: Systems biologists are interested in modelling chemical reactions in the intracellular environment, and to date much of what is done is based on the use of mass action kinetics to construct models of elementary reactions. Mass action kinetic models are based on a number assumptions which are not obviously valid in the intracellular environment. The cytoplasm is far from an ideal, isotropic wellmixed solution and often the concentrations of important chemical species are very small. Molecular crowding can have significant thermodynamic effects, but also must play an important dynamical role.
Interview on: The Vega Science Trust Fred Sanger is often considered the father of modern biology, and is one of the few people to have been awarded two Nobel prizes. Working in Cambridge he developed a new chromatographic method fo determining amino-acid end-groups. His new chromatographic results on the free amino groups of insulin were published in 1945 and the complete sequence of insulin in 1955.

Ronald Fox Georgia Institute of Technology Rectified Brownian Motion in Subcelluar Biology on: Fermilab Colloquium Lectures The mechanism of rectified Brownian motion will be described and applied to several sub-cellular processes. This mechanism is distinct from that of Brownian ratchets.
Computer History Museum Presents Steve Case in Conversation with Walt Mossberg on: It's been nearly 20 years since America Online was founded. The world was a very different place back then. Affordable PCs were just making their way into people's homes; cellular telephones weighed around two pounds each; CD technology was still in its infancy, and most people didn't even have cable television. Little did anyone know the Internet was about to transform nearly every aspect of their lives. It was Steve Case's belief that the online experience had unlimited potential to change the way society communicates, does business and learns about the world around us. During the past two decades, America Online, with Case at the helm, has been a key driver in pushing the Internet further into our everyday existence. Join us on January 12 as Case in conversation with Walt Mossberg, personal technology columnist for The Wall Street Journal, shares his shares his personal stories and discusses his perspectives on the Internet's amazing evolution.

Bending it like Beckham on: sciencelive Matt Cunningham chats to James Soper about how David Beckham is really a good scientisit as well as a good footballer. James shows Matt how the principles of different scientisits can be applied to his free kick against Greece in the World Cup Qualifiers.
