How quantum codes carrying classical messages gradually approach the ideal output distribution – like an artist nearing perfection, brushstroke by brushstroke.
Researchers at AI21 Labs have devised a method to reduce online reinforcement learning costs by sending some data to «take a nap» until better times.

Quantum Bursts of the Early Universe: How Logarithms Narrate Inflation
Physics & Space • General Relativity
During inflation, quantum fluctuations are stretched to cosmic scales, leaving mathematical «traces» – logarithms that help us understand the birth of the Universe's structure.

Quantum Investigation: How to Figure Out Which Box Your State Is Hiding In (and Why It's Harder Than It Seems)
Physics & Space • Quantum Physics
We figure out how many copies of a quantum state are needed to guess which set it came from, and why privacy makes this task exponentially harder.

When the Sky Looks «Lopsided»: What Radio Galaxies Reveal About Gravity
Physics & Space • Astrophysics
Radio galaxies show a strange spatial asymmetry three times stronger than Standard Model predictions – suggesting gravity might not work quite the way we thought.

The Orbital Dance of Neutrons: Unveiling the Music of Unbound States in Oxygen-20
Physics & Space • Nuclear Physics
A neutron transfer experiment in Oxygen-20 reveals the complex structure of quantum states at the boundary between boundedness and freedom.

When Darkness Births Light: How Invisible Particles Created Giants of the Cosmic Abyss
Physics & Space • Astrophysics
Discover how ghostly axions – particles of dark matter – could have birthed supermassive black holes at the very dawn of time, when the Universe was still an infant.
An exploration of how changing weights reveals a remarkable boundary where mathematical structures transition from chaos to order, much like water transforming into ice.

How to Teach a Computer to “Feel” Evolution: A Journey Through the Forest of Phylogenetic Trees
Biology & Neuroscience
Imagine that the evolutionary histories of genes are maps in nature's library. Discover how a new method helps to read these maps more accurately than ever before.
