The sixteenth edition of the internationally known Neutrino Telescopes conference will take place on March 2nd-6th 2015 in the usual venue of Palazzo Franchetti in Venice. This is a conference which gathers from around the world researchers who study neutrino physics and related topics. 
James D. Bjorken, also known as "BJ" by colleagues and physicists around the world, has been awarded the prestigious 2015 Wolf prize in Physics together with cosmologist Robert Kirshner. Bjorken deserves a lot of credit for his contribution to subnuclear physics: the official motivation is 

"For predicting scaling in deep inelastic scattering, leading to identification of nucleon's pointlike constituents "

Today I collected in my mailbox the hefty "Review of Particle Physics", the publication of the Particle Data Group which contains a summary of everything we know about subatomic particles. For the first time, the publisher is a Chinese journal: Chinese Physics C. This might be considered a detail, but it is a sign of times: China has been increasing its involvement in fundamental physics research in the last decade, and it may well become the leading country in this business in the future.
ATLAS sent today to the Cornell arxiv and to the journal JHEP their latest measurement of the top-antitop production asymmetry, and having five free minutes this afternoon I gave a look at the paper, as the measurement is of some interest. The analysis is done generally quite well, but I found out there is one things I do not particularly like in it... It does not affect the result in this case, but the used procedure is error-prone. 

But let's go in order. First I owe you a quick-and-dirty explanation of what is the top asymmetry and why you might care about it.
