Just... WOW. I did not expect this to happen in my lifetime (and no, I do not expect to die tomorrow either). The Atacama Large Millimeter Array in Chile has pictured a forming planetary system in a young star surrounded by a complex nebula of hot gas.I still remember the Scientific American article I read some 25 years ago about planet formation simulations, which showed how computer models of planetesimals rotating in a cloud of gas around a star. The planetesimals would pick up matter around as they swept the orbital plane, and in the matter of millions of years acquire a planetary mass and "clean up" the area around. Now we are seeing this before us, in the picture below offered by ALMA.
Results of a new search for single top production and large missing energy have been published by the ATLAS collaboration in a recent preprint. I think it is worthwhile to have a look at the idea behind this new search, as the signature of invisible particles produced in LHC collisions and escaping the detectors is important in many of the current and future investigations of beyond-the-standard-model physics.
Just a short entry to mention that the blog of my colleague Michael Schmitt, a professor at Northwestern University and a member of the CMS collaboration, is as active as ever, with several very interesting and well-written pieces recently published:
The Large Hadron Collider at the CERN laboratories in Geneva is currently in shutdown, finalizing the upgrades that will allow it to restart next year at the  centre-of-mass energy of 13 TeV - over 60% more than the last 8 TeV run. ATLAS and CMS have collected no more proton-proton collisions since almost two years ago; yet the collaborations are as busy as ever producing physics results from the analysis of the 2012 data.

Rather than focusing on any single result, below I give some highlights of the most recent publications by CMS. Another post will discuss ATLAS results in a few days.
"Two recent results from other experiments add to the excitement of Run II. The results from Brookhaven's g-minus-two experiments with muons have a straightforward interpretation as signs of supersymmetry. The increasingly interesting results from BABAR at the Stanford Linear Accelerator Center add to the importance of B physics in Run II, and also suggest new physics. I will be shocked and disappointed if we don't have at least one major discovery."
I am spending a few days in Aix Les Bains, a pleasant lakeside resort in the French southwest, to follow the works of the second ECFA workshop, titled "High-Luminosity LHC". ECFA stands for "European Committee for Future Accelerators" but this particular workshop is indeed centred on the future of the LHC, despite the fact that there are at present at least half a dozen international efforts toward the design of more powerful hadron colliders, more precise linear electron-positron colliders, or still other solutions.
