Some 2,400 metres below the Jinping Mountains in southwest China, the world’s deepest and largest underground laboratory has just opened. The enormous space is home to scientists who are hunting down dark matter — the hypothetical substance that is thought to make up more than 80% of the mass in the Universe. The China Jinping… Continue reading China’s New Dark Matter Lab Is Biggest and Deepest Yet

Never-Repeating Tiles Can Safeguard Quantum Information
This extreme fragility might make quantum computing sound hopeless. But in 1995, the applied mathematician Peter Shor discovered a clever way to store quantum information. His encoding had two key properties. First, it could tolerate errors that only affected individual qubits. Second, it came with a procedure for correcting errors as they occurred, preventing them… Continue reading Never-Repeating Tiles Can Safeguard Quantum Information
Inside the Crime Rings Trafficking Sand
Transnational security investigator Abdelkader Abderrahmane set out from the Moroccan city of Kenitra with two research assistants to inspect sand-mining sites on the Atlantic Ocean coast. They drove across the dry, flat terrain for six kilometers, the last stretch on a rutted dirt road that had them crawling in low gear, windows closed against the… Continue reading Inside the Crime Rings Trafficking Sand

Babies Exposed to COVID in the Womb Are More Likely to Suffer Breathing Problems
More than four years after the virus that causes COVID first appeared, scientists continue to discover new ways that the illness threatens pregnant people and babies—as well as additional evidence that vaccination offers significant protection. A new study finds that babies born to women who got COVID while they were pregnant were three times more… Continue reading Babies Exposed to COVID in the Womb Are More Likely to Suffer Breathing Problems
A Quantum Trick Implied Eternal Stability. Now It’s Falling Apart.
For a true phase transition in one dimension, mathematicians had proved that two of these exponents must be greater than 2. But the MBL simulations had found them to be 1 — a major disagreement. In a still-unpublished preprint posted in 2015, Oganesyan and Chandran, together with Christopher Laumann of Boston University, showed that the… Continue reading A Quantum Trick Implied Eternal Stability. Now It’s Falling Apart.
‘Entropy Bagels’ and Other Complex Structures Emerge From Simple Rules
Repetition doesn’t always have to be humdrum. In mathematics, it is a powerful force, capable of generating bewildering complexity. Even after decades of study, mathematicians find themselves unable to answer questions about the repeated execution of very simple rules — the most basic “dynamical systems.” But in trying to do so, they have uncovered deep… Continue reading ‘Entropy Bagels’ and Other Complex Structures Emerge From Simple Rules

This Tiny Marsupial Gives Up Sleep for Sex, Then Drops Dead
January 25, 2024 3 min read The mouselike male antechinus goes all out for its first and final mating season By Jack Tamisiea Dusky antechinus marsupial on moss at Mount Wellington in Hobart, Tasmania, Australia. During the breeding season, time is not on a male antechinus’s side. These carnivorous marsupials, which resemble a mousy shrew,… Continue reading This Tiny Marsupial Gives Up Sleep for Sex, Then Drops Dead
Maze Proof Establishes a ‘Backbone’ for Statistical Mechanics
Imagine that a grid of hexagons, honeycomb-like, stretches before you. Some hexagons are empty; others are filled by a 6-foot tall column of solid concrete. The result is a maze of sorts. For over half a century, mathematicians have posed questions about such randomly generated mazes. How big is the largest web of cleared paths?… Continue reading Maze Proof Establishes a ‘Backbone’ for Statistical Mechanics
