Studying circadian rhythms in plants and their pathogens might lead to precision medicine for people

Precisely calibrated timekeepers are found in organisms from all domains of life. Biologists are studying how they influence plant/pathogen interactions – what they learn could lead to human medicines.

Why the Deep Space Atomic Clock is key for future space exploration

Measuring time is a crucial part of navigation – particularly in space, where exacting precision is called for. The DSAC is poised to make a change that will aid future deep space missions.
