Scientists in Australia are deep-freezing the shoot tips of a critically endangered tree to preserve its DNA in case the species goes extinct.
Only 380 specimens of the angle-stemmed myrtle (Gossia gonoclada) remain in the wild, with about 300 of them concentrated in the City of Logan area in southeast Queensland. If scientists manage to cryopreserve a diverse collection of genes from the species, there is a good chance they could resurrect it if it ever dies out, researchers said.
