## Sun’s Puzzling Plasma Recreated in a Laboratory

The twisting loops of the sun’s magnetic field control the flow of charged particles throughout the solar system. For the first time, researchers have created a scale model of this mysterious environment.

## Quantum Darwinism, an Idea to Explain Objective Reality, Passes First Tests

Three experiments have vetted quantum Darwinism, a theory that explains how quantum possibilities can give rise to objective, classical reality.

## Cellular Life, Death and Everything in Between

The discovery that apparently dead cells can sometimes resurrect themselves has researchers exploring how far they can push the point of no return.

## Curious About Consciousness? Ask the Self-Aware Machines

Consciousness is a famously hard problem, so Hod Lipson is starting from the basics: with self-aware robots that can help us understand how we think.

## 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, which describes what happens during the long-mysterious “collapse” of a quantum system.

## How to Understand the Universe When You’re Stuck Inside of It

Lee Smolin has a radical idea for how to understand an object with no exterior: Imagine it built bit-by-bit from relationships between events.

## The Simple Idea Behind Einstein’s Greatest Discoveries

Lurking behind Einstein’s theory of gravity and our modern understanding of particle physics is the deceptively simple idea of symmetry. But physicists are beginning to question whether focusing on symmetry is still as productive as it once was.

## When Magic Is Seen in Twisted Graphene, That’s a Moiré

What do moiré patterns seen in optics, art, photography and color printing have to do with superconducting layers of graphene?

## A 53-Year-Old Network Coloring Conjecture Is Disproved

In just three pages, a Russian mathematician has presented a better way to color certain types of networks than many experts thought possible.
