COLUMBIA- A researcher at the University of Missouri discovered how a person's mental workload can be measured by pupil dilation. Mental workload can be defined as the amount of work one's brain ...

Scientists from the University of California San Diego School of Medicine are suggesting Alzheimer’s disease may be detected years before symptoms appear by examining pupil dilation. The new study ...

Neuroscientists have shown that a person's hearing can be assessed by measuring dilation of the pupils in eyes, a method that is as sensitive as traditional methods of testing hearing. University of ...

The botched launch of two global-positioning satellites four years ago has proven to be a real gift to physicists. Scientists have used the Galileo 5 and Galileo 6 spacecraft to measure "gravitational ...

In a dual set of papers published in Science last week, an international group of researchers presented an experiment which used relativistic time dilation to measure the curvature of spacetime. The ...
