TL;DR: These data represent the first measurement of the EMC effect for (3)He at large x and a significant improvement for (4)He and suggest that the nuclear dependence of the quark distributions may depend on the local nuclear environment.

TL;DR: The Qweak experiment has measured the parity-violating asymmetry in polarized e-p elastic scattering at Q2 = 0.025(GeV/c)2, employing 145 microamps of 89% longitudinally polarized electrons on a 34.4cm long liquid hydrogen target at Jefferson Lab.
