How Artificial Light Rewires the Nighttime Brain
We usually talk about light pollution as an astronomy problem. We lament losing sight of the Milky Way, or we worry about confused wildlife. But artificial light at night does not just stay outside on our streets. It reaches through our windows, creeps past our curtains, and interacts directly with the neurological machinery inside our […]
Give the Night a Summer Vacation
Summer is usually the season for kicking back, turning off alarm clocks, and enjoying a slow evening on the porch. But while humans get to unplug, the night sky never actually gets a break. Every single evening, city streets, glowing storefronts, and oversized backyard floodlights switch on at full blast. Instead of cool, dark skies, […]
The Streetlight Trap: How Artificial Light Is Tricking Autumn Trees
Every autumn, deciduous trees pull off one of nature’s most impressive tricks. They do not actually wait for the cold to start preparing for winter. Instead, they count the hours of daylight. As the days shorten, sensitive proteins inside their leaves act like a biological clock, telling the tree it is time to wrap up […]
Why Artificial Light is a “Glitch” in Insect Evolution
For centuries, the sight of a moth circling a flame or a beetle battering itself against a porch light has been dismissed as a strange, obsessive attraction. We coined the phrase “like a moth to a flame” to describe irresistible, self-destructive desire. However, modern biology has revealed that this behavior is far from a choice. […]
Designed or Just Installed: Is Your City’s Lighting Actually Designed?
Walk through any modern city at night, and you are surrounded by a sea of artificial glow. At first glance, this lighting seems purely functional, a sign of progress and safety. But if you take a closer look, a critical question emerges: Was this space actually designed, or was the lighting simply installed? The distinction […]
Reclaiming the Stars: Why the Future of Lighting is a Shared Mission
For most of human history, the night sky was our first storybook, our primary calendar, and our most constant map. Today, however, a “starry night” is a luxury. As urban centers expand, the glow of artificial light has veiled the heavens, creating a barrier between humanity and the cosmos. But light pollution is more than […]
Project presented at Regional Erasmus+ Cluster Meeting and Contact-Making Seminar in Colombia

Illuminating a Sustainable Future: Five Pillars for Tackling Light Pollution
The perpetual glow of modern civilization has created an invisible, yet profoundly harmful, environmental challenge: light pollution. It’s not simply a matter of wasted energy or blocked stargazing; it’s a form of environmental contamination that disrupts sleep, interferes with nocturnal wildlife behavior, and obscures one of humanity’s oldest natural resources, the night sky. To reverse this […]
Does darkness matter more than we think?
In one of our previous articles „From Darkness to Light: Sustainable Solutions for Light Pollution Mitigation“ we have discussed basics of light pollution and it`s effects on human health, environmental and economical impact. Why Darkness Matters Darkness is more than just the absence of light but it is a natural condition that has shaped life […]
