The practice of keeping time hinges on stable oscillations. In a grandfather clock, the length of a second is marked by a single swing of the pendulum. In a digital watch, the vibrations of a quartz crystal mark much smaller ...

This week, we reported on LIGO upgrades, parasitic fungi and a new analysis of Curiosity rover data. Also, did you know that viruses also attack bacteria? But at that scale, it's a lot less like catching a cold and a lot ...
In 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO), made history when it made the first direct detection of gravitational waves—ripples in space and time—produced by a pair of colliding black holes.
