BaBar's window on the weak force

The sun is shining; the Earth is warm instead of icy. Life is good, thanks to the weak force. One of the four known forces that shape the universe, the weak force sustains our lives, driving the nuclear reactions that power the sun and heat the Earth’s core. It’s also tremendously useful.

Evolution of a collider

As physicists and engineers devise ways to make the International Linear Collider perform better at a lower cost, the design evolves, sometimes with tweaks but at other times with major reconfigurations.

ANITA takes flight

A one-time visitor to SLAC, the Antarctic Impulsive Transient Antenna (ANITA), recently took to the frigid skies over Antarctica on a mission looking for evidence of cosmic-ray neutrinos.
