| This is actually a nutria—not to be confused with a neutrino, which would have far less mass |
Scientists at the Fermi National Accelerator Laboratory in Batavia, Illinois, announced yesterday the first results of the MINOS experiment, which corroborate an experimental result from 1998 that suggested that a class of subatomic particles called neutrinos have mass. This deviates from the Standard Model of particle physics—which predicts the number and behavior of subatomic particles and depends on a massless neutrino—and indicates that the model needs to be revised, or replaced with a more accurate one. Now, if we could only find the Higgs boson. —Martha Harbison
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
