Matthias Seeger Max Planck Institute Experimental Design for Efficient Indentification of Gene Regulatory Networks using Sparse Bayesian Models on: Identifying large gene regulatory networks is an important task, while the acquisition of data through perturbation experiments (e.g., gene switches, RNAi) is expensive. It is thus desirable to use an identification method that effectively incorporates available prior knowledge --- such as sparse connectivity --- and that allows to design experiments such that maximal information is gained from each one. Our main contributions are twofold: a method for consistent inference of network structure is provided, incorporating prior knowledge about sparse connectivity.
Was the Universe Made for Us? on: sciencelive Matt Cunningham chats to Dr Carolin Crawford and Prof Bernard Carr on whether the Universe was made for us? The characteristics of the Universe are just right to allow human life to have evolved, what does this imply and what can it tell us about the Universe around us.
Harry Kroto Florida State University Astrophysics Lecture 4: Origin of the Elements on: Vega Science Trust Origin of the elements and the formation of molecules in the interstellar medium: Big Bang synthesis, stellar synthesis of He and C and other elements, interstellar scattering, interstellar species such as carbon monoxide and more complex molecules.
V. S. Ramachandran University of California, San Diego The Uniqueness of the Human Brain on: Google Video Lecture 6 of 12. Ramachandran discusses phantom limbs and synesthesia (esp. color-blind synesthete) as a function of neuron innervation. Specifically, he focuses on cross-linking between nearby cortical regions, which he believes to be genetically caused
Martin Nowak Harvard University Evolutionary Dynamics on: Harvard University Professor Martin Nowak discusses recent advances in our understanding of evolutionary dynamics and its application to genes, quasispecies, games, cooperative behavior, and human language.
Ian Swanson California Institute of Technology Ian Swanson: Tangled Physics: Superstring Theory and the AdS/CFT Conjecture on: Caltech Ian Swanson, a graduate student in physics at Caltech, discusses the quantum field theory is known as the Standard Model of particle physics, providing the most accurate physical predictions in the history of science. Physicists must now unite the Standard Model with the tenets of general relativity, and string theory is arguably the most promising candidate of the last 50 years.
Rep. Henry Waxman Rep. California Diabetes drug at center of House hearing on: Yahoonews Rep. Henry Waxman held a congressional hearing about Avandia Wednesday, after an analysis that appeared last month in the New England Journal of Medicine concluded the drug could raise patient's risk of heart attack by more than 40 percent.

E. O. Wilson Harvard University E. O. Wilson - The Coming Synergism Between Science and the Humanities on: Google Video Scientist and author Edward O.Wilson, draws on studies from a broad spectrum of disciplines to show how various fields of inquiry, and especially the humanities and sciences, intersect with each other. According to Wilson, 'the greatest enterprise of the mind has always been and always will be the attempted linkage of the sciences and the humanities.' Series: Frontiers of Knowledge
Beer Today, Champagne Tomorrow? on: sciencelive Charlotte interviews three of the actors from 'beer today, champagne tomorrow', a play about climate change in east anglia through looking at the beer and wine industry. The scientists turned thespians decided to explore climate change through a play to find new ways to communicate science. They also wanted to show that what scientists do in their labs has have a real effects in the world.
