### How (Relatively) Simple Symmetries Underlie Our Expanding Universe

Although Einstein’s theory of space-time seems more complicated than Newtonian physics, it greatly simplified the mathematical description of the universe.

### How Swarming Insects Act Like Fluids

By studying a swarm of flying midges as though it were a fluid, physicists have learned how collective behaviors might stabilize a group against environmental disruptions.

### How Randomness Can Make Math Easier

Randomness would seem to make a mathematical statement harder to prove. In fact, it often does the opposite.

### The Quantum Theory That Peels Away the Mystery of Measurement

A recent test has confirmed the predictions of quantum trajectory theory.

### Philosophers Debate New ‘Sonic Black Hole’ Discovery

Opinions differ about what recent measurements of a sound-trapping fluid reveal about light-trapping black holes.

### A New Law to Describe Quantum Computing’s Rise?

Neven’s law states that quantum computers are improving at a “doubly exponential” rate. If it holds, quantum supremacy is around the corner.

### A Close Look at Newborn Planets Reveals Hints of Infant Moons

Astronomers have discovered a complex planetary system still swirling into existence.

### Do Brains Operate at a Tipping Point? New Clues and Complications

New experimental results simultaneously advance and challenge the theory that the brain’s network of neurons balances on the knife-edge between two phases.

### Immune Cells Measure Time to Identify Foreign Proteins

Immunologists confirm an old hunch: T-cells identify what belongs in the body by timing how long they can bind to it.
