Video: What Hitler tried to teach Germans and ALL Whites
White peoples minds have been so rotted and misled on extremely important questions that I think most whites, and even many National Socialists (NAZIS) dont comprehend some of the lessons Hitler was trying to teach the Germans.

The last two northern white rhinoceroses on Earth will never bear young, but they may have genetic offspring nonetheless.
Scientists harvested eggs from the only two living northern white rhinos. Here, Najin recovers after her eggs are collected, while Fatu (Najin’s daughter) undergoes the same procedure in another enclosure.
Just two northern white rhinoceroses exist in the world. Now, though, this critically endangered subspecies has a new, slim chance at survival: two lab-created embryos that could grow to maturity, according to an announcement made Wednesday (Sept.11).
The international team of researchers has been working to save the northern white rhino (Ceratotherium simum cottoni) for years using in-vitro fertilization. Now that researchers have successfully fertilized two of these eggs, the next step would be to implant the lab-created embryos in the uteruses of members of a closely related subspecies, the southern white rhino.
“The entire team has been developing and planning these procedures for years,” Thomas Hildebrandt, a biologist from the Leibniz Institute for Zoo and Wildlife Research in Germany, said in a statement. “Today, we achieved an important milestone on a rocky road which allows us to plan the future steps in the rescue program of the northern white rhino.”

Last of their kind
The northern white rhinoceros likely went extinct in the wild in 2007 or 2008. Though a small number of the animals survived in zoos, most of the living individuals were aging or had health problems that precluded them carrying young. In 2018, the last male northern white rhino, Sudan, died, leaving only two members of the species, both female, alive.
The new embryos count those two living rhinos as their mothers. The maternal rhinos, Najin and Fatu, were both born at Dv?r Králové Zoo in the Czech Republic and now live at Ol Pejeta Conservancy in Kenya. Neither will be able to carry their embryos to term. Najin is too old, and Fatu has uterine problems that make pregnancy impossible.

But in late August, scientists successfully harvested eggs from both female rhinos. The researchers then used a procedure called intra cytoplasm sperm injection to fertilize the eggs with frozen sperm from two northern white rhino males named Suni and Saut. Suni died in 2014, and Saut died in 2006.

Of the 10 eggs harvested, seven were suitable for fertilization, according to one of the researchers involved, Cesare Galli, of Avantea Laboratories in Cremona, Italy. Ultimately, only two matured into viable embryos. Both of those were created with Fatu’s eggs and Suni’s sperm. The embryos have now been frozen to preserve them for future transfer.

Saving a subspecies
To bring the embryos to term, scientists still have to perfect the art of embryo transfer in rhinos. Researchers will also have to find a healthy southern white rhinoceros (Ceratotherium simum) or two to carry the pregnancy.
“Five years ago, it seemed like the production of a northern white rhino embryo was [an] almost unachievable goal — and today we have them. This fantastic achievement of the whole team allows us to be optimistic regarding our next steps,” Jan Stejskal, the director of communications and international projects at the zoo where Najin and Fatu were born, said in the statement.
To truly bring back the northern white, though, will take more than a few successful rounds of in vitro fertilization. Scientists have only two living reservoirs for eggs and have stored sperm from only four northern white rhinoceros bulls. That leaves little genetic diversity for resurrecting the species. But tissue banks do have nongamete tissues (meaning any tissue except the sperm and egg) stored from other northern whites, which would expand the gene pool to 12 rhinos. Researchers are now working on stem cell technology to transform these regular tissue samples into sperm and eggs.
