Under the sea ice during the Arctic’s pitch-black polar night, cells power photosynthesis on the lowest light levels ever observed in nature. The post How Does Life Happen When There’s Barely Any Light? first appeared on Quanta Magazine

Is the universe flat and infinite, or something more complex? We can’t say for sure, but a new search strategy is mapping out the subtle signals that could reveal if the universe had a shape. The post Cosmologists Try a New Way to Measure the Shape of the Universe first appeared on Quanta Magazine

In the late 19th century, Karl Weierstrass invented a fractal-like function that was decried as nothing less than a “deplorable evil.” In time, it would transform the foundations of mathematics. The post The Jagged, Monstrous Function That Broke Calculus first appeared on Quanta Magazine

Individual cells in the brain light up for specific ideas. These concept neurons, once known as “Jennifer Aniston cells,” help us think, imagine and remember episodes from our lives. The post Concept Cells Help Your Brain Abstract Information and Build Memories first appeared on Quanta Magazine

Heat is supposed to ruin anything it touches. But physicists have shown that an idealized form of magnetism is heatproof. The post Heat Destroys All Order. Except for in This One Special Case. first appeared on Quanta Magazine

A new proof marks the first progress in decades on important cases of the so-called kissing problem. Getting there meant doing away with traditional approaches. The post Mathematicians Discover New Way for Spheres to ‘Kiss’ first appeared on Quanta Magazine

Certain grammatical rules never appear in any known language. By constructing artificial languages that have these rules, linguists can use neural networks to explore how people learn.

Inside the proton, quarks and gluons shift and morph their properties in ways that physicists are still struggling to understand. Rithya Kunnawalkam Elayavalli brings to the problem a perspective unlike many of their peers.

It’s surprisingly difficult to prove one of the most basic properties of a number: whether it can be written as a fraction. A broad new method can help settle this ancient question. The post Rational or Not? This Basic Math Question Took Decades to Answer. first appeared on Quanta Magazine

Hypothetical devices that can quickly and accurately answer questions have become a powerful tool in computational complexity theory. The post Why Computer Scientists Consult Oracles first appeared on Quanta Magazine

Evolution was fueled by endosymbiosis, cellular alliances in which one microbe makes a permanent home inside another. For the first time, biologists made it happen in the lab. The post Scientists Re-Create the Microbial Dance That Sparked Complex Life first appeared on Quanta Magazine

Biologists used artificial intelligence to make discoveries about molecules and the brain, and overturned long-held assumptions about the immune system and RNA. The post The Year in Biology first appeared on Quanta Magazine

Physicists discovered strange supersolids, constructed new kinds of superconductors, and continued to make the case that the cosmos is far weirder than anyone suspected. The post The Year in Physics first appeared on Quanta Magazine

Landmark results in geometry and number theory marked an exciting year for mathematics, at a time when advances in artificial intelligence are starting to transform the subject’s future. The post The Year in Math first appeared on Quanta Magazine

To make progress on one of number theory’s most elementary questions, two mathematicians turned to an unlikely source. The post Mathematicians Uncover a New Way to Count Prime Numbers first appeared on Quanta Magazine

In a first, researchers have shown that adding more “qubits” to a quantum computer can make it more resilient. It’s an essential step on the long road to practical applications. The post Quantum Computers Cross Critical Error Threshold first appeared on Quanta Magazine

Cells in our bodies are constantly dying — and these countless tiny deaths are essential to human health and multicellular life itself. In this episode, co-host Steven Strogatz speaks with cellular biologist Shai Shaham about what makes a cell “alive” and the latest developments in understanding how and why cells die. The post How Is Cell Death Essential to Life? first appeared on Quanta...
