The paper reports the cloning of two endangered Przewalski's horse stallions from cryopreserved fibroblast cells, marking the first successful production of multiple healthy clones for an endangered species.

Researchers cloned an endangered black-footed ferret using cross-species somatic cell nuclear transfer, producing three healthy kits to aid genetic rescue.

Point-and-click correction of misassemblies on Hi-C heatmaps, paired with the automated 3D-DNA pipeline, gave chromosome-length wombat, opossum and raccoon scaffolds from just short-insert DNA-Seq and in situ Hi-C reads.

The paper analyzes genomic data from passenger pigeons and their relatives to show that natural selection reduced neutral genetic diversity despite large population size, challenging previous extinction theories.
