Of all the particles in the world of particle physics, neutrinos are by far the shyest. They don't like to socialize with other particles, and generally keep to themselves. A hundred trillion neutrinos pass through you every second, but it would take a week for just one to interact with a single particle in your body. That's too bad, because neutrinos are important for our understanding of the universe — they make up a lot of the energy from supernovas, for one thing, and knowing more about them might teach us important things about the mysterious substance scientists call dark matter. But physicists are on the case, and in August 2017, a team announced that they had detected a rare neutrino interaction. Even better, instead of using a building-sized detector buried deep underground, the researchers did it with a device the size of a fire extinguisher.
