Clocks are at the heart of GPS. Advances in space-qualified atomic clocks that kept time to within 10 nanoseconds over a day were a key development that made GPS possible. It turns out that GPS must ...

The omicron variant of COVID-19 has once again evolved, spawning new versions of itself with slight mutations that could make the virus more transmissible or more dangerous.

The new Omicron-based booster, which targets both the original and Omicron BA.4/5 variants, “is a good move for sure,” says Kwong, to improve people’s protection from getting infected.
