The wellness world already has a language for invisible necessities. Vitamin D comes from sunlight. Vitamin N, in its usual meanin...
Somewhere within the Milky Way, another massive star is moving toward its final moments. Astronomers estimate that our galaxy experiences roughly two or three supernova explosions every century, making such an event statistically likely every 30 to 50 years. Yet the night sky has remained unusually quiet.
For decades, neutrinos have challenged scientists with their extraordinary ability to pass through matter almost undisturbed. They are constantly streaming across Earth in unimaginable numbers, yet detecting even a tiny fraction of them requires enormous, highly sensitive instruments.
The opening moments of cosmic history remain among the deepest unsolved problems in modern science. Although the Big Bang successfully describes how the universe evolved from an extremely hot, dense state, it leaves unanswered what, if anything, existed before that event.
For decades, cosmologists have described the universe using a model in which its invisible ingredients coexist without directly influencing one another. A new study now suggests that this picture may be missing an important piece. Researchers at the University of Sheffield report evidence that dark matter and neutrinos could interact, a possibility that challenges one of the long-standing assumptions of modern cosmology and offers a fresh perspective on how the universe developed.
Deep beneath a Japanese mountain, a detector has spent thousands of days listening for one of the universe's faintest signals. Its latest indication adds another piece to the story of how neutrinos reveal stellar history, while raising broader questions about continuous particle flux, material response, and the boundary between detection physics and energy conversion research.
For more than a century, electricity has meant connection. A household had power if it was linked to a chain: extraction, conversion, transmission, distribution, pricing, maintenance, regulation. Each link had a cost. Each link had a geography. Each link had a political condition and a point of failure.
