Could IVF save the world’s last northern white rhinos from extinction?

The world’s last male northern white rhino is suffering from what may be a fatal infection—but that doesn’t necessarily mean the end of his kind, Associated Press reports. Scientists plan to use in-vitro fertilization (IVF) to breed new calves, taking eggs from the two remaining females and fertilizing them with sperm that has been stored from dead males. Neither of the females can carry a calf, so the fertilized embryos would have to be implanted in a southern white rhino surrogate mother. But scientists are in a race against time: They haven’t yet perfected the IVF technique for rhinos, and more research is needed.
