'Hopeful' Scientists Create Nearly Extinct Northern White Rhino Embryo

By Jessie Wingard

Scientists are hoping to impregnate the closely-related southern white rhino — the most abundant rhino sub-species in the world — using harvested eggs from the last two northern white rhino cows and frozen sperm collected from four rhino bulls before their deaths, an international science consortium said on Wednesday.


Turning Point in Assisted Reproduction

Two northern white rhino in-vitro embryos were successfully created at Avantea Laboratories in Cremona, Italy.

"These are early embryos that have a very high potential to develop into a baby. [They] have now been put in liquid nitrogen. We have achieved a new life, a new hope for this species," Thomas Hildebrandt, project head at the Leibnitz Institute for Zoo and Wildlife Research, a consortium partner in the project, told DW.

Researchers from Kenya, Italy, the Czech Republic, and Germany are still fine-tuning the implantation procedure before the embryos are transferred into a surrogate mother, but are hopeful a northern white rhino calf can be born via surrogacy within the next three years.

Mother's Bond

The remaining two cows, mother Najin and daughter Fatu, live in a Kenyan sanctuary. The last bull, Fatu's father, Sudan, died in March, 2018.

Genetic reasons mean neither cow can breed.

While Najin and Fatu might not be able to carry the baby, the offspring would still be reliant on them "to pass on their knowledge of how a northern white rhino behaves with their offspring," Hildebrandt added.

A new study is shedding light on just how much ice could be lost around Antarctica if the international community fails to urgently rein in planet-heating emissions, bolstering arguments for bolder climate policies.

The study, published Thursday in the journal Geophysical Research Letters, found that over a third of the area of all Antarctic ice shelves — including 67% of area on the Antarctic Peninsula — could be at risk of collapsing if global temperatures soar to 4°C above pre-industrial levels.

This week, Secretary Haaland chose a visit to Bears Ears National Monument as her first trip as Interior Secretary. She is spending three days in Bluff, Utah, a small town just outside the monument, listening to representatives of the five tribes who first proposed its designation to President Obama in 2015. This is the same town where former Secretary Sally Jewell spent several hours at a public hearing in July 2016 before recommending the monument's designation to President Obama.

The coronavirus has isolated many of us in our homes this year. We've been forced to slow down a little, maybe looking out our windows, becoming more in tune with the rhythms of our yards. Perhaps we've begun to notice more, like the birds hopping around in the bushes out back, wondering (maybe for the first time) what they are.
