"The power of mathematics is that we can devise models that reproduce experimentally observed data and make concrete predictions about what will happen next," Karamched said.

"But nobody has experimentally shown this in non-human animals," he says.

Although quantum spin liquids exist in theory and have been modelled by scientists, it has not previously been possible to produce them experimentally or to find them in nature.

“Now, the authors say that spacetime coordinates are matrices, but what does that mean for the experimentally tested Standard Model whose quantum fields live in classical spacetime?”

Scullin noted that experimentally increasing sleep improved these positive attributes, which are at the core of well-being and among the underpinnings of prosocial behaviors.
