Like it or not, human-enhanced global warming is an established scientific fact. Indeed, as much as we hate the idea that we are affecting the future living conditions of hundreds of millions of human beings (not to mention animal species) with our carbon dioxide emissions, most of us - reasonable people with no agenda or direct interests in polluting industries - agree on the fact, and most of us also agree that we are doing far too little to alleviate the dramatic ongoing phenomenon. The science is out, and while it is a healthy thing to question the data and the results in all cases, it is a far healthier thing to accept evidence when it is overwhelming.
Ever since telescopes were first invented, by some dutch lens grinder in the late XVIth century, and then demonstrated to be invaluable tools for investigating the cosmos around us by Galileo Galilei in the early 1600s, there has been a considerable, steady effort to construct bigger and better ones. Particularly bigger ones.
I'll admit, I wanted to rather title this post "Billionaire Awards Prizes To Failed Theories", just for the sake of being flippant. But in any joke there is a little bit of truth, as I wish to discuss below.
The (not-so-anymore) news is that the "Special Breakthrough prize" in fundamental physics, instituted a decade ago by Russian philantropist Yuri Milner, and then co-funded by other filthy wealthy folks, recently went to three brillant theoretical physicists: Sergio Ferrara, Dan Freedman,  and Peter van Nieuwenzhuizen, who in the seventies developed an elegant quantum field theory, SuperGravity. 
Our current understanding of the Universe includes the rather unsettling notion that most of its matter is not luminous - it does not clump into stars, that is. Nobody has a clue of what this Dark Matter (DM) really is, and hypotheses on what it could be made of are sold at a dime a dozen. 
On the other hand, we clearly see the gravitational effects of DM on galaxies and clusters of galaxies, so the consensus of the scientific community is that one of those cheap theories must be true. What make this very close to a dream situation for an experimental scientist is the fact that we do have instruments capable of detecting, or ruling out, dark matter behaving according to most of the majority of those possibilities. 
While you and I may have been lagging behind a bit as of late, excused by a particularly hot July, the CMS collaboration has kept grinding its data, producing exquisite new results from the large amounts of proton-proton collisions that the experiment has been collecting during Run 2, i.e. until last year. 
Of course, the process of going from subatomic collisions to submitted papers is a long and complex one. The first part of the journey involves triggering, storage, and reconstruction of the acquired datasets, and reduction of the data into an analysis-friendly format. While this might sound like a partly automatic and painless procedure, it involves the expense of liters of sweat by conscentious collaborators who oversee the data acquisition and their processing.
