Summary

Story summary

Andrea Stöllner of the Institute of Science and Technology Austria led researchers who developed a laser trap for a single aerosol particle.
The method lets researchers observe how particles accumulate and release charge, informing lightning initiation.
Stöllner's experiments indicate ice crystals in clouds may play a crucial role.
Current theories say weak cloud electric fields are insufficient for lightning.
The study, published in Physical Review Letters, examines particle charging dynamics.
