Quasicrystals Spill Secrets of Their Formation
New studies of the ‘platypus of materials’ help explain how their atoms arrange themselves into orderly, but nonrepeating, patterns.
‘It’s a Mess’: A Brain-Bending Trip to Quantum Theory’s 100th Birthday Party
Hundreds of physicists (and a few journalists) journeyed to Helgoland, the birthplace of quantum mechanics, and grappled with what they have and haven’t learned about reality.
Earth’s Core Appears To Be Leaking Up and Out of Earth’s Surface
Strong new evidence suggests that primordial material from the planet’s center is somehow making its way out. Continent-size entities anchored to the core-mantle boundary might be involved.
Why Did The Universe Begin?
In this episode of The Joy of Why, Thomas Hertog discusses his collaboration with Stephen Hawking on a provocative theory arguing that the laws of physics evolved with the universe, and how this could have shaped a cosmos fit for life.

AI Comes Up with Bizarre Physics Experiments. But They Work.
Artificial intelligence software is designing novel experimental protocols that improve upon the work of human physicists, although the humans are still “doing a lot of baby-sitting.”
The Biggest-Ever Digital Camera Is This Cosmologist’s Magnum Opus
Tony Tyson’s cameras revealed the universe’s dark contents. Now, with the Rubin Observatory’s 3.2-billion-pixel camera, he’s ready to study dark matter and dark energy in unprecedented detail.
Physicists Start To Pin Down How Stars Forge Heavy Atoms
The precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses. They definitely exist in East Lansing, Michigan.
Matter vs. Force: Why There Are Exactly Two Types of Particles
Every elementary particle falls into one of two categories. Collectivist bosons account for the forces that move us while individualist fermions keep our atoms from collapsing.
Is Gravity Just Entropy Rising? Long-Shot Idea Gets Another Look.
A new argument explores how the growth of disorder could cause massive objects to move toward one another. Physicists are both interested and skeptical.
