Our own Dr. Mario Motta will be giving a talk on "Human & Environmental Health Effects of LED Lighting on Our Night Skies" at the Rockport Public Library on Wednesday 9/25 at 5:00 pm. Mario's an engaging and dynamic speaker, and an internationally-acknowledged expert on the topic. If you can attend, this would be time well-spent. Seating is limited to 50, and registration is free.
