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.

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.
