Study Reveals How Age Affects Perception of White LED Light

Study Reveals How Age Affects Perception of White LED Light Although LEDs are increasingly used in low-energy lighting and displays, consumers sometimes find their light harsh or unpleasant. Findings from a new study point to the need to take age-related perception differences into account when designing white LED lighting that is more pleasing to the eye. Read more »

ALAN May Be Increasing West Nile Virus Spillover from Wild Birds

ALAN May Be Increasing West Nile Virus Spillover from Wild Birds We're in the midst of summertime mosquito bite season and cities across the country are reporting a heightened number of West Nile Virus (WNV) cases. The house sparrow is one of the most common carriers of WNV in urban areas. Mosquitos feed off the infected birds and spread the virus to humans. New research finds house sparrows exposed to artificial light at night, such as what's used in parking lots, maintain higher burdens of WNV for longer than those who spend their nights in the dark.

3D Bio-Optical Models Reveals How the Human Body Uses the Entire Solar Spectrum

3D Bio-Optical Models Reveals How the Human Body Uses the Entire Solar Spectrum History teaches that global changes to the public's environment mandate a higher level of scrutiny to ensure that we first do no harm. In "Melatonin and the Optics of the Human Body" published in the journal Melatonin Research, Zimmerman and Reiter combine optical ray tracing from lighting and ESR data from the medical industry to model for the first time the 3D free radical distributions generate by lighting sources in the human body.
