The proposed new body clock measures DNA methylation -- the process by which genes are altered as the body’s cells differentiate and their genetic programs change to meet new demands.

Now optical clocks function in about the same manner as microwave atomic clocks, but they measure atoms or ions that are oscillating at frequencies 100,000 times higher than cesium, ...

Clock angle dependence of the field-aligned current as reproduced by SMRAI2 (IMAGE) Research Organization of Information and Systems ...

These new clocks can measure one of Albert Einstein’s predictions—time dilation due to gravity—on the smallest scale yet. Cutting-edge atomic clocks such as these use neither cesium nor quartz.

Angles measure the size of a turn in degrees. You can show degrees using the symbol ° after the number of degrees. Imagine two lines acting like the hands of a clock.

Scientists developed a portable optical atomic clock that helped them more accurately measure both time and space on top of a ... Clock Invention Measures How Much Faster You Age On A Mountaintop.
