Blue Light From Street Lamps Linked to Colorectal Cancer

Exposure to blue light from outdoors has been linked to an increased risk of developing colorectal cancer in a study. Scientists found a positive association between the amount of light in the blue spectrum shining near people’s homes at night and rates of colorectal cancer. They found no link between overall visual light and the […]

Study draws Southern California coastal light pollution into focus

When tides are at their highest a few days after a full or new moon, thousands of small silver fish called grunion flop onto Southern California beaches. Females wriggle their tails into the sand, males spray the females with sperm, and the fertilized eggs are deposited below the beach surface. The entire affair lasts no […]

Chemists discover how blue light speeds blindness

lue light from digital devices and the sun transforms vital molecules in the eye’s retina into cell killers, according to optical chemistry research at The University of Toledo. The process outlined in the study, which was recently published in the journal Scientific Reports, leads to age-related macular degeneration, a leading cause of blindness in the United States. […]

Blinding Nemo: Artificial lights prevent clownfish eggs from hatching

As the world gets brighter, it could get a lot harder to find baby clownfish like Nemo. In a new study, published in Biology Letters, researchers exposed clownfish to artificial light to simulate light pollution. The experiment included 10 clownfish pairs, half of which were placed in aquariums that had low levels of light shone on them […]

Lights at Night Turn Nocturnal Pollinators Off

Pollination is essential for the reproduction of many plant species. Some flowering plants rely on the wind or water to spread their pollen, but most depend on animals for pollination. Insects like bees, moths, and beetles are the largest group of animals to help with this process. Unfortunately, the worldwide spread of light pollution may […]

Bird Migration Dramatically Altered by High-intensity Urban Light Installation

Tribute in Light in New York City projects two beams of light into the sky as an annual memorial to the victims of 9/11. The tribute also occurs during peak bird migration in North America. Recognizing a unique opportunity, a team of scientists and volunteers gathered each year at the memorial on September 11 since 2005 […]

A New Frontier in Disease Prevention: Lightbulbs

Artificial light: It stresses our eyeballs, fiddles with our biological clocks, and may even contribute to obesity. These are just a few of the health concerns associated with indoor lighting in the developed world. But in warm, developing countries, light bulbs can be literal beacons for human disease when buildings aren’t uniformly equipped with screens […]

Pollinators Really Hate Light Pollution

It’s hard enough to grab an insect during the day, so try doing it in the dark, while wearing night-vision goggles. These eyepieces offer little in the way of depth perception, and “catching insects without that is not easy,” says Eva Knop from the University of Bern. Nevertheless, she and her colleagues persisted, and became better with […]

More Lights, More Diseases?

Light pollution is known to cause all kinds of problems. Studies show how it can throw sleep cycles out of whack and disrupt the natural ecosystem. Now biology researchers at the University of South Florida suggest yet another unintended consequence of artificial lights: They may help the spread of vector-borne diseases like the West Nile virus. read more:
