Scientists observed cuttlefish engaging in tentacle waving, a behavior that may serve as a form of communication. This discovery suggests that cuttlefish use visual and vibrational signals to interact, expanding our understanding of cephalopod intelligence. How Cuttlefish Use Tentacle Waves Researchers studied common cuttlefish (Sepia officinalis) and dwarf cuttlefish (Sepia bandensis), identifying four distinct arm ...
The universe is supposed to run on rules, yet the deeper astronomers look, the stranger those rules seem to become. With every new space telescope or detector we launch, the cosmos offers up another puzzle that bends our expectations, and sometimes our patience. For all our breakthroughs in physics, from black holes to exoplanets, ...
For hundreds of years, the women of South Korea’s Jeju Island have dived into freezing seas, diving as deep as 10 meters (33 feet) without oxygen, in search of abalone, sea urchins, and octopuses. They are called Haenyeo, or “women of the sea,” and they keep up this physically demanding labor well into their 80s, ...
Canada was previously a world champion of climate action, but ahead of the heat of the 2025 federal election, Canada’s political leadership is quietly stepping away from the environment and into the arms of fossil fuel development. Only four years ago, climate change ranked as the most important issue on voters’ minds, prompting lawmakers to ...
Across the Americas, long before steel, written blueprints, or modern surveying tools, Indigenous engineers were quietly reshaping landscapes on a continental scale. Their cities lined up with the stars, their earthen pyramids rivaled Old World monuments, and their roads cut straighter than many modern highways. Yet for generations, textbooks either skipped these achievements or ...
Forests have a way of turning familiar ground into alien territory the moment you step off the trail, but in some corners the fear runs deeper than folklore. Beneath the roots and needles lie unstable slopes, gas-charged springs, disappearing lakes, and histories carved by fire, ice, and tectonic violence. These places unsettle us not ...
They look like scratches on stone, but Viking runes are far more than angular letters carved by long-dead hands. Hidden in those lines is a record of magnetic storms, social upheaval, coded insults, and even early attempts at “going viral.” As physicists increasingly read nature the way archaeologists read artifacts, these runes have turned ...
Stand in front of a mirror, stare at your own eyes for long enough, and your face may seem to warp, blur, or even become strangely unfamiliar. That eerie feeling is not a glitch in the glass; it is your brain quietly editing reality on the fly. From optical illusions that break the internet ...
The universe has an origin story that most of us learn in a single phrase: the Big Bang. But in the last two decades, that once-daring idea has started to look almost conservative compared with what cosmologists are now proposing. From bouncing universes to cosmic inflation fields and simulated realities, new theories are chipping ...
Most days, the weather feels comfortingly familiar: clouds roll in, rain falls, the forecast more or less behaves. But every so often, the sky does something so strange it feels like a glitch in reality, as if the laws of physics briefly forgot how they’re supposed to work. Around the world, scientists have been ...
