Kind: research · Impact: low

## In brief

- The anomalous Kovacs effect, a memory phenomenon, has been experimentally observed in a granular system for the first time.
- The report is published in APS Physics as Physics 19, s141, by Ryan Wilkinson, dated November 10, 2026.

## Why it matters

It shows that granular materials can retain a memory of their earlier state, a behaviour previously studied mainly in glassy systems, which may inform how physicists model disordered and granular matter.
