The northern white rhino is all but extinct. The two last male died several years ago. Two females are still with us, but too feeble to bear babies. In an Italian lab their eggs are now artificially fertilised by sperm from the three late males, and kept at minus 196 celsius, in hopes that surrogate rhinos from another sub species can carry the northern white back from the brink.
