Combined measurements of the W boson mass from the CDF and D0 collaborations at Fermilab yield a smaller ellipse (green) in top-W mass space than the one from previous data (orange). The white stripe is the band allowed for the Higgs boson mass by data from direct searches. Both Letters selected for an Editors' Suggestion and a Synopsis in Physics. [V. M. Abazov et al.
