Contributions to this community are meant to invite discussion, so posts that don't allow comments at all aren't appropriate here. They're perfectly fine on the pages of the contributors. In particular, posts on topics that carry the sensationalistic headlines of the popular press are discouraged, since the aim of this forum is to educate non-specialists and not to provide an echo chamber for noise rather than signal. So there's nothing to the subject of the radius of the proton. The discrepancy between calculation and experiment is, essentially, due to effects of strong interactions, that haven't been calculated, yet, to the requisite precision. It's a question of computational resources, not of principle. 

Higgs Hunting: learning how events are analyzed in particle physics experiments, when trying to find the Higgs boson. What's particularly nice is that it's interactive.

Well, even big science can fall prey to small impediments.

The LHC had to go off-line overnight because a weasel chewed through a power cable. The little guy paid the ultimate price for his pranksterism, though.

``Understanding the physics of these violent events allows scientists to better understand how the seeds of chemical complexity and life itself have been scattered in space and time in our Milky Way galaxy.
"All heavy elements in the universe come from supernova explosions. For example, all the silver, nickel, and copper in the earth and even in our bodies came from the explosive death throes of stars," said Steve Howell, project scientist for NASA's Kepler and K2 missions at NASA’s Ames Research Center in California's Silicon Valley. "Life exists because of supernovae." ''

The suspected discovery of an atomic nucleus with four neutrons but no protons has physicists scratching their heads. If confirmed by further experiments, this “tetraneutron” would be the first example of an uncharged nucleus, something that many theorists say should not exist. “It would be something of a sensation,” says Peter Schuck, a nuclear theorist at the National Center for Scientific Research in France who was not involved in the work. Details on the tetraneutron appear in the Feb. 5 Physical Review Letters.
