TL;DR: In this article, the authors report on the first of several experimental upgrades to improve the statistical sensitivity of their atomic electric dipole moments (EDM) measurements by orders of magnitude and evaluate systematic effects that contribute to current and future levels of experimental sensitivity.

TL;DR: The 2011 Workshop on Fundamental Physics at the Intensity Frontier as discussed by the authors identified and described opportunities at the intensity frontier in the areas of heavy quarks, charged leptons, neutrinos, proton decay, new light weakly-coupled particles, and nucleons, nuclei, and atoms.

TL;DR: The root-mean-square (rms) nuclear charge radius of the most neutron-rich of all particle-stable nuclei was determined for the first time to be 1.93(3) fm as discussed by the authors.

TL;DR: Based on precision laser spectroscopy on individual 6He atoms confined and cooled in a magneto-optical trap, the nuclear charge radius of 6He is determined for the first time in a method independent of nuclear models to be 2.054+/-0.014 fm.

TL;DR: In this article, the authors used a laser-based atom-counting method to measure the age of groundwater from the Nubian Aquifer. But their results indicate that the 81Kr method for dating old groundwater is robust and such measurements can now be applied to a wide range of hydrologic problems.
