Quantifying the Impact of Light on K-12 Students' Performance and Well-being
The LRC received a grant from the U.S. Green Building Council to quantify the impact of daylight and electric lighting on student alertness, performance, and well-being in K-12 schools. The final outcome will be a set of guidelines to enable the development of school building designs to maximize health and performance.

First Device to Measure Light as it Impacts the Circadian System
Evidence indicates that exposure to irregular patterns of light and dark can cause circadian disruption, negatively affecting human health. LRC researchers have developed a first-of-its-kind framework for studying the effects of circadian disruption on breast cancer, obesity, sleep disorders, and other health problems.

A New Pathway to Alertness
It is well-accepted that the circadian system is maximally sensitive to short-wavelength (blue) light. However, working with the Office of Naval Research, LRC scientists found that red light also increased alertness at night although it did not suppress the hormone melatonin, a marker of the circadian clock..
