Koalas’ population comeback may be doing more than boosting numbers—it could also be rebuilding their lost genetic diversity.

When DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key repair process called homologous recombination, the cell uses loops in its ...
