Light pollution, or artificial light at night (ALAN), is a widespread phenomenon in areas with dense human populations. Normally, animals use natural external cues, like sunlight and temperature, to ...

Artificial light spilling into coastal waters from cities, ports, roads and hotels is disrupting sleep in coral reef fish and ...

You may have seen reports late last month about a new study showing how too much light at night is affecting birds — the latest sign of a problem that has implications for us, too. The study’s ...

Excess light at night can contribute to air pollution, according to a study by scientists at the National Oceanic and Atmospheric Administration (NOAA) and the Cooperative Institute for Research in ...

Birds like this western meadowlark are singing earlier in the morning and later at night thanks to light pollution. Light pollution is causing non-nocturnal species of birds to sing for 50 additional ...

In the early 20th century, canaries were used as early warning systems in coal mines to alert miners to rising levels of carbon monoxide. A small unremarkable fish may fill a similar role in coastal ...

The flight paths of individual moths were tracked using radar. On the left a large yellow underwing (Noctua pronuba) with a transponder. The increasing use of artificial light at night is one of the ...

Exposure to outdoor light at night could put people at a higher risk of developing Alzheimer’s disease (AD), according to a new study published in Frontiers in Neuroscience. "We show that, in the U.S.

Excessive artificial light at night (ALAN) doesn’t just pollute the sky. It may also pollute the brain. That’s according to a surprising new study focused on light pollution and Alzheimer’s disease ...

Artificial light pollution is a lesser-known factor contributing to the decline of pollinator species. Light pollution negatively impacts nocturnal pollinators like moths and bats, disrupting their ...

Global light pollution has increased by at least 49% over 25 years, new research shows. This figure only includes light visible via satellites, and scientists estimate the true increase may be ...
