We don’t know if dark matter exists. So why do astronomers keep looking?

A comparison of star-forming galaxies suggests, surprisingly, that dark matter and visible matter do interact – taking us closer to understanding what keeps the galaxies together.

A decade of science and trillions of collisions show the W boson is more massive than expected – a physicist on the team explains what it means for the Standard Model

A decadelong experiment produced the most accurate measurement yet of the mass of W bosons. These particles are responsible for the weak force, and the result is more evidence for undiscovered physics.
