“Every day I see these beautiful animals on the way to extinction,” says zookeeper James Mwenda. It was in the flying Kenyan jungle. Against hunting K-9 dogs barking in the background. “I saw their numbers go from 7 to 2…working with them and seeing what happened was an emotional meltdown.” He smiled, clearly coming to terms with the pain of witnessing it. “But I gave up my life.”

The Bioengineering Gambit To Save The Northern White Rhino

The disappearance ended quickly. If left alone in the wild, the two remaining rhinos are the quiet old Najin and her 20-year-old daughter, Fatu Wilde. They will be among the last animals to graze the grasslands of Africa. After civil war, habitat loss and poaching, scientists declared the species extinct in the wild in 2008.

Scientists now have one last chance to bring the northern white rhino back from space due to the decay of stem cells, but only if they can overcome the obstacles of the epidemic.

Hope for the northern rhino,” said Dr. Thomas Hildebrand, a Berlin-based wildlife expert. But inspired by an interactive conference on interstellar life, Hildebrand used the grant to create an international association that seeks to save species. “We knew we weren’t going to finish. Suddenly a new sky opened before us.

He has led BioRescue, a collaboration between the Leibniz Institute for Zoo and Wildlife Research, Dvůr Králové Zoo in the Czech Republic, Avantea Laboratory in Italy and Ol Pejeta in Kenya, and the Kenya Wildlife Service. Hildebrand believes that increased international cooperation is the future of conservation, sharing resources without expectation of return. “It’s moral,” he said.

Covid-19 disrupted BioRescue’s 2019 momentum, interrupting travel and diverting scientific funds. They wondered if they could harvest more eggs from the aging Fatou and Nagin and send them to a lab in Italy during the global outbreak.

How we answer this question will determine not only the future of rhinos, but also our ability to pioneer conservation efforts for other species.

The stakes couldn’t be higher. The northern white male rhino is no longer alive after the beloved Sudan was killed by a humanitarian in 2018 at the age of 45. Ol Pejeta employs intensive security measures against the relentless threat of poaching: armed guards, electric fences, special K-9 units, surveillance cameras and aircraft surveillance.

In 2014, scientists discovered that 20-year-old Fatou was unable to conceive naturally, and recently Najin’s mother had a large tumor in her abdomen next to her left ovary, which could lead to a miscarriage. It affects the egg collection process . Najin’s back legs are weak and the vets believe that a 16-month pregnancy-resources for the mother and baby weighing 100 kg will cause a lot of stress.

Northern White Rhinos: The Audacious Plan That Could Save A Species

In December, BioRescue collected 14 eggs from Fatu using an ultrasound probe. Even if sperm can freeze, an unborn egg cannot. So Fatu’s egg will travel better than all of us in 2021. They spent the night on a charter flight from Nairobi to Frankfurt and then flew to the Avantea laboratory in Cremona, Italy.

Once upon a time in Italy, Fatu’s eggs matured and fused with the sperm of Suni, a cow born in 1980. (Although he died of natural causes in 2014, Suni’s sperm was collected at an early age. It is believed that his sperm was healthier than that collected from older Sudanese men.Let the number of frozen embryos increase to five.

Although Suni is dead and Fatu is unable to conceive, science has dubbed the pair the future of the northern white rhino.

World First Research Gets Closer To Creating Northern White Rhino Egg Cells To Save Species

In November 2015, I joined an NGO dedicated to eradicating extreme poverty among women in Nanyuki, Kenya. Before heading further north for our fieldwork, we entered the Ol Pejita reserve after a short but heavy rain. There I saw the last remains of several species: a handful of zebras, giraffes, bears, and — above an electric fence and armed guards — three northern white rhinos. Sudan is still alive.

I passed Ol Pejeta’s rhinoceros cemetery, where there was a sign that said, “In memory of the rhino hunt in the nature reserve since 2004.” I stood near the tomb of Sam Sa, a female rhino shot with her horns. Rhino poaching is a serious, calculated and daily threat to both rhinos and rangers.

There are no more northern male rhinos alive after the humanitarian slaughter in Sudan in 2018

That November, I photographed Sudan and Nagin on their 700-acre grounds. Now the photo reminds me of the last passenger pigeon named Martha or the last parrots Carolina, Inca and Lady Jane. As the population declines, speciation occurs. Growing personal relationships make investing more urgent and losses more difficult to bear.

Poaching Surges In The Birthplace Of White Rhino Conservation

Mwenda believes he will step down as Ol Peyeta’s guardian after Sudan’s death. “No one wants to be associated with failure,” he said. “No one wants to see a dead face.”

Mwenda remembers a day three years ago before Sudan was put to sleep. I stood with him in the field and fed him bananas. I look at her lovely face with pleasure. I think he had a good time. But then I looked at her and saw her covered in tears. I know scientists say rhinos don’t cry. But I think maybe he felt empty. – I put my hand on him. After a day I decided it wasn’t about selfies with rhinos and pictures of species. The last animal. It’s about preparation

Mwenda thinks a lot about baby Fatura. Soon his mother Najin’s age and cancer took her down. “Fatu is the end,” says Mwenda. “This is his truth. He must take responsibility as the last man. It will be a symbol of political and human greed. This is what his loneliness is. That’s his job.”

BioRescue must balance short-term goals such as egg retrieval and embryo freezing with ambitious, long-term plans.

Do The World’s Three Remaining Northern White Rhinos Have A Future?

First, the scientists inserted Suni and Fatu’s embryos into a southern white rhinoceros, a rhinoceros-like species that split from the northern rhino about a million years ago. Owuan, a spayed southern white cow, arrives at the shelter in early December to signal when the female is in heat, increasing the chances of embryo reproduction.

Fortunately, frozen embryos are not the only way. Nobel Prize-winning scientist Shinya Yamanka’s work on mice shows that by transforming skin cells into stem cells, gametes, or as the casual reader might think: experimental rhinos can be formed. According to Hildebrand, there are enough skin cell patterns to create the genetic diversity needed for a healthy future population. In 20-30 years, the population will increase in alternative refuges and sanctuaries. One day—perhaps when Fatu and the original scientists are gone—the northern white rhino will return to Uganda, the most accessible country in the rhino’s range.

The embryos are currently stored in a liquid nitrogen container kept at 19196°C with a back-up generator for added safety. In theory, the embryo could still function for thousands of years, waiting for science to catch up.

I’m referring to Norway’s Svalbard Global Seed Vault, also known as the Doomsday Vault. I imagine the sperm and eggs resembling a bank for the endangered species, a Noah’s ark that freezes, where the embryos of Fatou and Suni join the bear, the bear and the right whale. The so-called biological bank.

Eggs Successfully Collected From The Last Two Northern White Rhinos

But liquid nitrogen cannot replace what Hildebrand calls “social cognition.” It is very important for northern rhino babies to spend time with Fatu and Najin to learn the correct head position for grazing. “Southern white rhinos can milk northern white rhinos,” says Hildebrand. “But it’s not species-specific knowledge.”

How do we determine which species should be economical and to what extent? How do we notice when we are imposing Western conservation standards and the consequences on other nations – for example, punishing you? Hungry areas looking for bush or asking them to change long-held cultural beliefs and practices? Is nature conservation a global problem? These questions will be asked more and more as the planet goes through its sixth great extinction.

I ask BioRescue if there is a moral way for conservation communities to prioritize spending on extinction prevention. For example, do we like animals that have
