Artificial light at night is a threat to astronomical research, personal safety, and the health of both humans and wildlife. The problem is worsening with the proliferation of LED billboards and blue-rich white light LEDs as an option for street lighting. Within five years, LED technology will take over as the dominant type of outdoor lighting technology. With this in mind, scientists and lighting engineers say now is the time to implement strategies for reducing light pollution. By working together, they are identifying the best type of LED to use while suggesting actions that minimize intrusive lighting.

Harvard University researchers have designed more than 1,000 new blue-light emitting molecules for organic light-emitting diodes (OLEDs) that could dramatically improve displays for televisions, phones, tablets and more.

A new study has found brief periods of exposure to blue light could increase subsequent activation in brain regions important to successful working memory performance and improve response times, according to an article by Medscape Multispecialty.

Each April 2, 2014, Autism Speaks celebrates Light It Up Blue along with the international autism community, in commemoration of the United Nations-sanctioned World Autism Awareness Day.
