Scientists used artificial intelligence to discover new details about how particles interact. They studied dusty plasma, a mixture of gas and tiny charged particles. The AI model was able to describe forces with over 99% accuracy.

Dusty plasma is often called the fourth state of matter. It's made up of ionized gas filled with interacting charged particles, including tiny grains of dust. This system can be found in many environments, from space to Earth's atmosphere. Scientists at Emory University used a machine learning approach to study dusty plasma and its properties.

Their AI model was able to describe non-reciprocal forces with more than 99% accuracy. These forces are difficult to measure and model. The team believes this method could be applied broadly to systems made up of many interacting components, such as industrial materials or groups of living cells.

The study's findings were published in the journal PNAS. The research was primarily supported by the National Science Foundation, with additional funding from the Simons Foundation.
