What evidence suggests that the Earth's inner core is less solid than previously assumed, and what are the immediate implications of this discovery?

A new study from the University of Southern California (USC) reveals potential structural changes near Earth's inner core, suggesting it may be less solid than previously believed. Researchers analyzed seismic waveforms from 121 repeated earthquakes, finding unusual properties that indicate temporal changes in the inner core's shape. This challenges the long-held assumption of a completely solid inner core.
