Mathematicians Prove Symmetry of Phase Transitions

By ALLISON WHITTEN

A group of mathematicians has shown that at critical moments, a symmetry called rotational invariance is a universal property across many physical systems.

‘Social’ Mitochondria, Whispering Between Cells, Influence Health

By KATARINA ZIMMER

Mitochondria appear to communicate and cooperate with one another, both within and between cells. Biologists are only just beginning to understand how and why.

A New Kind of Information-Coding Seen in the Human Brain

By ELENA RENKEN

Brain activity is usually measured by the rate at which neurons fire, but new research suggests that exactly when each neuron fires also holds key information.

A New Twist Reveals Superconductivity’s Secrets

Podcast hosted by SUSAN VALOT;
Article by CHARLIE WOOD

An unexpected superconductor was beginning to look like a fluke, but a new theory and a second discovery have revealed that emergent quasiparticles may be behind the effect.

Optimal Encryption
Black holes scramble information so well that no machine learning algorithm — not even a quantum one — can unscramble it, as physicists Zoë Holmes and Andrew Sornborger write in Scientific American. While we may never decode a black hole’s signals, the information should in theory persist. That’s the conclusion of a recent series of breakthrough papers, as George Musser reported for Quanta last year.


Flash Dance
From a 3D movie of flashing fireflies, researchers confirmed key details of an explanation for why dense swarms of the lightning bugs tend to blink in unison, Sabrina Imbler reports for The New York Times. Fireflies are just one instance of synchrony in nature. Mathematicians recently grappled with new “chimera” systems that only partially sync up, Natalie Wolchover reported for Quanta in 2019.
