Sudan, world’s last male northern white rhino, dies at Kenyan conservancy

Sudan leaves behind only two other northern white rhinos, but artificial reproductive technologies could provide a future for the subspecies.

The world’s last male northern white rhino has died.

The 45-year-old rhino named Sudan was euthanized after veterinarians observed him suffering “a great deal” following treatment for an age-related disorder, according to a statement from Kenya’s Ol Pejeta Conservancy.

“We at Ol Pejeta are all saddened by Sudan’s death,” said Richard Vigne, Ol Pejeta’s CEO. “He was a great ambassador for his species and will be remembered for the work he did to raise awareness globally of the plight facing not only rhinos, but also the many thousands of other species facing extinction as a result of unsustainable human activity.”

Sudan became somewhat famous in 2017 after Tinder dubbed him “the most eligible bachelor in the world” as part of an effort to raise funds and awareness for the endangered subspecies. He was adored by those who cared for him, stealing “the hearts of many with his dignity and strength,” according to the conservancy’s statement.

“He was a gentle giant, his personality was just amazing and given his size, a lot of people were afraid of him,” Elodie Sampere, a representative for Ol Pejeta, told CNN. “But there was nothing mean about him.”

The planet now has only two northern white rhinos: Sudan’s daughter Najin, and her daughter Fatu.

Poaching and northern white rhinos

In the 1970s and 1980s, poachers reduced the wild northern white rhino population from hundreds to just 15. The subspecies made a modest comeback in the 1990s and early 2000s, but poachers again drove them to near extinction.

The high demand for rhino horns in Asian countries like Vietnam, Taiwan, and Japan, where they’re used as part of traditional Chinese medicine, has been catastrophic for rhino populations. The horn of the northern white rhino used to sell for more than $22,000 per pound, making it more valuable than gold or cocaine.

In 2009, the last four fertile northern white rhinos—two males and two females—were moved from Dvůr Králové Zoo in the Czech Republic to Kenya’s 90,000-acre Ol Pejeta Conservancy. The hope was for the rhinos to breed and save the species, but all attempts—including those to breed hybrid offspring with a southern white rhino, a similar and more populous subspecies—failed.

But northern white rhinos might still have a future. On Monday, researchers collected Sudan’s genetic material with hopes that technology could one day revive or resurrect the subspecies.  

“There is a possibility that it could be saved through artificial reproductive techniques—in particular, in vitro fertilization,” Vigne told The Independent.

He added that the fate of the northern white rhino could portend worse things to come if humanity doesn’t change course.

“The northern white rhino stands as a symbol to that, and a sign that if the way we consume doesn’t change, then sooner or later we are going to destroy the planet and the ecological processes on which we as humans depend. For me, that is the key message.”

Space toilets: How astronauts boldly go where few have gone before

A NASA astronomer explains how astronauts dispose of their, uh, dark matter.

  • When nature calls in micro-gravity, astronauts must answer. Space agencies have developed suction-based toilets – with a camera built in to ensure all the waste is contained before "flushing".
  • Yes, there have been floaters in space. The early days of space exploration were a learning curve!
  • Amazingly, you don't need gravity to digest food. Peristalsis, the process by which your throat and intestines squeeze themselves, actually moves food and water through your digestive system without gravity at all.

Can the keto diet help treat depression? Here’s what the science says so far

A growing body of research shows promising signs that the keto diet might be able to improve mental health.

Mind & Brain
  • The keto diet is known to be an effective tool for weight loss, however its effects on mental health remain largely unclear.
  • Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
  • Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.
