New today in @Nature: "Our findings challenge the prevailing perspective that changes in light radiance are largely gradual and unidirectional. Instead, the nightlights of Earth are surprisingly dynamic."

And some reporting on the study and its implications by @skyandtelescope: https://skyandtelescope.org/astronomy-news/light-pollution-is-increasingly-volatile-around-the-world/

New research suggests that artificial light at night exposure in inpatient clinical settings could be a modifiable risk factor for improving #schizophrenia symptoms and preventing relapses. “ALAN exposure may increase the risk of schizophrenia relapse, potentially mediated by gut microbiota and linoleic acid metabolism.”

In the timelapse, it is hard to identify the meteors because too many planes and satellites cross the image.

This #timelapse is based on unretouched images and covers a time period of 2 hours.

Um belo texto de Paul Bogard, autor do livro “The End of Night: Searching for Natural Darkness in an Age of Artificial Light” (2013), lembrando a influência dos LED no agravamento drástico da #PoluiçãoLuminosa (10% por ano, como apontam os mais recentes estudos, aqui trazidos recentemente).

O greenwashing da iluminação, segundo Anna Levin.

"Our results ... highlight the complexity of using spectral manipulation as a mitigation measure, and the need for further consideration of ALAN in environmental management and planning, to limit the exposure and impact of cascading effects of artificial light at night on food webs and communities."

"This study suggests that ALAN does not necessarily prevent high-metabolic nocturnal insectivores from achieving their energetic needs, which might help explain their persistence in urban environments."
