While iSCAT enables researchers to "track" individual particles and observe rapid changes inside cells, it lacks the wider view offered by QPM.

Although these particles are far too small to see, the electric current they produce flows through wires in a way that resembles water moving through a pipe.

This ability allows them to generate the particles responsible for the "knee" and those that extend beyond it.

As a result, the smallest "particle" in those models usually represents a group of roughly 100 stars, which averages away the behavior of individual stars and limits the accuracy of small-scale processes.

Cloud seeding involves spraying particles such as silver iodide and salt into clouds from aircraft to trigger rain.
