Symmetry Magazine: Ways to weigh a neutrino

This was an assigned story I wrote for Symmetry, an online magazine about particle physics, on international collaborations and experiments to obtain a direct measurement of the mass of a neutrino, the lightest known particle in the universe. It includes interviews with four experts in neutrino science. I had no previous experience with neutrino science before writing this article. I interviewed one additional expert to educate myself about the topic.
