135. Steven Chu is the Secretary of Energy
Via Cosmic Variance:
This is fantastic news. Steven Chu, director of the Lawrence Berkeley National Lab and 1997 Nobel Laureate in Physics for his work in laser cooling of atoms, has been nominated to be the next Secretary of Energy in the Obama administration. (Thanks to Elliot in comments.) This post is enormously important for science in general and physics in particular, as the DOE is responsible for much of the funding in physics and a lot of other R&D work. It?s also, needless to say, a crucial position for determining the country?s energy policy at a time when strong and imaginative leadership in this area is crucial.
It is so great to feel that I was wrong about Obama and he is going to actually listen scientists. Moreover, he is going to listen them every single day during his morning briefing

134. Cosmic strings – simple and nice introduction into the topic
After my recent post on textures I have been asked what could a newcomer to the field read about topological defects in cosmology apart from the canonical book by Vilenkin and Shellard that I’ve recommended?

131. Non-gaussianities from postinflationary universe
Mark Trodden and Alessandra Silvestri have recently released a paper about signatures of non-gaussianity from the post-inflationary early Universe.
The title of the paper is speaking for itself: one can immediately recall that CMB fluctuations can be generated from cosmic strings and other topological defects, i.e., they may be partially sourced by various phase transitions in the very early Universe. This is indeed what Mark and Alessandra consider – in particular, they focus on effects of textures.
