The mom in the end died from an an infection, however an post-mortem revealed that the 6.5cm male fetus was growing effectively and had a 95% likelihood of being born alive, demonstrating {that a} viable being pregnant by rhino IVF is feasible.

There are 30 treasured northern white rhino embryos. The subsequent step could be to repeat the success with a few of these embryos.

With human exercise inflicting what the World Large Fund for Nature (WWF) calls “catastrophic” lack of species, it typically looks like we do not hear a lot excellent news about nature.

However a ten-year research confirmed that conservation measures are efficient in lowering world biodiversity loss.

Scientists from dozens of analysis establishments examined 665 trials of conservation measures throughout international locations and oceans and located that that they had a optimistic impact in two out of three instances.
