In July 1977, a massive blackout occurred in New York City which had a very unexpected result – residents saw a rare glimpse of the Milky Way usually obscured by artificial light.

The event underscored how urban lighting erases natural darkness, a growing problem that now prevents one-third of the world’s population, including 80% of North Americans, from seeing the Milky Way.

Beyond diminishing the night sky, excessive artificial lighting disrupts ecosystems. It disorients migratory birds, insects, and trees while threatening nocturnal wildlife, including sea turtles that rely on celestial light for navigation. Human health is also at risk, with research linking light pollution to conditions like sleep disorders, depression, and obesity.

However, unlike other environmental crises, light pollution is relatively easy to fix. Turning off unnecessary lights, using shielded fixtures, and adopting lower-intensity, warm-colored lighting can make a significant impact. Some communities like Crestone, Colorado, have embraced darkness, earning recognition as a Dark Sky community. Organizations like DarkSky International advocate better lighting policies, with initiatives spreading across Europe and beyond.

Despite progress, challenges remain. Urban expansion continues to spread artificial glow, and some experts fear that future generations may never experience truly dark skies. Yet, growing awareness and policy changes offer hope that the stars may one day be visible again to more people worldwide.

The project cost nearly $500 million in federal funding. It spanned over 10 years and across three continents. More than 250 researchers contributed to the results.

The results of what? The dazzling details of a brain atlas—a 3-D map of the brain and its 170 billion brain cells that fall into 3,000 categories. Considered the most complex organ, this was no easy feat since each area of the brain is equal to another very complex organ. No wonder the results required 21 published papers across multiple journals.

What do the findings tell us? That while the human brain cells are similar to other primate brains, it’s how those cell types are combined that differentiates the cognitive abilities. According to John Ngai, director of the brain initiative, the reason neurological and neuropsychiatric disorders are challenging is because they don’t know what portion of the brain isn’t optimally functioning. With more research, he believes they can determine how the brain becomes susceptible to complex disorders such as autism and schizophrenia since “the cool thing here is this (brain atlas) gives us a way in.”

Articles about this research couldn’t begin to cover the project’s depth, magnitude or future potential but perhaps this neuroscientist’s comment puts it into perspective: “This is like building a map of the universe.”
