Chemists discover how blue light speeds blindness
Blue 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.
Ten Brighter Ideas? An Explorable Explanation
As with many areas of public interest, the common wisdom surrounding energy conservation consists of myths and legends, rules of thumb and superstitions. We're given guidelines as soundbites, catchy but insubstantial. We trust them blindly, not knowing whether our actions make any significant impact.
The Great Lightbulb Conspiracy
The Phoebus cartel engineered a shorter-lived lightbulb and gave birth to planned obsolescence
Appropriate Measures — Real Life
Changing the tech we use is not enough to mitigate the environmental and social harm of mass technology
You have been mislead about lightbulbs (Maurycy's blog)
This is wrong, but it's the type of wrong that cites its sources and hides in the part you'd never think to fact check:
The sky is psychedelic: why so many people see strange lights in the sky
Your brain evolved to see deep meaning in the sky. And UFOs.

Predictive processing frameworks for perception can explain recent drone sightings in the United States
We draw on the predictive processing theory of perception to explain why healthy, intelligent, honest, and psychologically normal people might easily misperceive lights in the sky as threatening or extraordinary objects, especially in the context of WEIRD (western, educated, industrial, rich, and democratic) societies. We argue that the uniquely sparse properties of skyborne and celestial stimuli make it difficult for an observer to update prior beliefs, which can be easily fit to observed lights. Moreover, we hypothesize that humans have likely evolved to perceive the sky and its perceived contents as deeply meaningful. Finally, we briefly discuss the possible role of generalized distrust in scientific institutions and ultimately argue for the importance of astronomy education for producing a society with prior beliefs that support veridical perception.
