I received from Ravi Kuchimanchi, the author of a paper to be published in Phys. Rev. D, the following summary, and am happy to share it here. The paper is available in the arxiv.
Are laws of nature left-right symmetric? 


Besides being a giant triumph of theoretical physics and the definitive seal on the correctness of the Standard Model -at least at the energies at which we are capable of investigating particle physics nowadays-, the 2012 discovery of the Higgs boson by the CMS and ATLAS collaborations opens the way to new searches of new physics.

The Higgs boson is one more particle we know how to identify now, so we can now focus on new exotic phenomena that might produce Higgs bosons in the final state, and entertain ourselves in their search.
"The era of the atom" is a new book by Piero Martin and Alessandra Viola - for now the book is only printed in Italian (by Il Mulino), but I hope it will soon be translated in English.
I used to post on this blog very abstruse graphs from time to time, asking readers to guess what they represented. I don't know why I stopped it - it is fun. So here is a very colourful graph for you today. You are asked to guess what it represents. 



I am reluctant to provide any hints, as I do not want to cripple your fantasy. But if you really want to try and guess something close to the truth, this graph represents a slice of a multi-dimensional space, and the information in the lines and in the coloured map is not directly related. Have a shot in the comments thread! (One further hint: you stand no chance of figuring this out).
It is galaxy season in the northern hemisphere, with Ursa Mayor at the zenith during the night and the Virgo cluster as high as it gets. And if you have ever put your eye on the eyepiece of a large telescope aimed at a far galaxy, you will agree it is quite an experience: you get to see light that traveled for tens or even hundreds of millions of years before reaching your pupil, crossing sizable portions of the universe to make a quite improbable rendez-vous with your photoreceptors. 
Particle physics is so cool - you get to build huge detectors with a specific goal clearly stated in your letter of intents and technical proposals, but are then allowed to use them to study many other things.
