Physicists Create a Holographic Wormhole Using a Quantum Computer
The unprecedented experiment explores the possibility that space-time somehow emerges from quantum information, even as the work’s interpretation remains disputed.
The Brain Uses Calculus to Control Fast Movements
Researchers discover that to sharpen its control over precise maneuvers, the brain uses comparisons between control signals — not the signals themselves.
AI Reveals New Possibilities in Matrix Multiplication
Inspired by the results of a game-playing neural network, mathematicians have been making unexpected advances on an age-old math problem.
The Gut Microbiome Helps Social Skills Develop in the Brain
New research in fish suggests that gut microbes can have a crucial early influence on the brain’s social development.
New Chip Expands the Possibilities for AI
An energy-efficient chip called NeuRRAM fixes an old design flaw to run large-scale AI algorithms on smaller devices, reaching the same accuracy as wasteful digital computers.
How Supergenes Fuel Evolution Despite Harmful Mutations
Supergenes that lock inherited traits together are widespread in nature. Recent work shows that their blend of genetic benefits and risks for species can be complex.
Ocean Bacteria Reveal an Unexpected Multicellular Form
Marine bacteria normally seen as single cells join together as a “microscopic snow globe” to consume bulky floating carbohydrates.
Brightest-Ever Space Explosion Reveals Possible Hints of Dark Matter
A recent gamma-ray burst known as the BOAT — “brightest of all time” — appears to have produced a high-energy particle that shouldn’t exist. For some, dark matter provides the explanation.
Experiments Spell Doom for Decades-Old Explanation of Quantum Weirdness
Physical-collapse theories have long offered a natural solution to the central mystery of the quantum world. But a series of increasingly precise experiments are making them untenable.
Mathematicians Discover the Fibonacci Numbers Hiding in Strange Spaces
Recent explorations of unique geometric worlds reveal perplexing patterns, including the Fibonacci sequence and the golden ratio.
