'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.
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.

Scientists have recorded Antarctica's first documented heat wave, warning that animal and plant life on the isolated continent could be drastically affected by climate change.
A case that has bounced around the lower courts for 13 years was finally settled yesterday when the U.S. Supreme Court upheld a lower court decision, finding oil giant Citgo liable for a clean up of a 2004 oil spill in the Delaware River, according to Reuters.

The amount of energy generated by tides and waves in the last decade has increased tenfold. Now governments around the world are planning to scale up these ventures to tap into the oceans' vast store of blue energy.
When the novel coronavirus started to sweep across the country, the National Park Service started to waive entrance fees. The idea was that as we started to practice social distancing, Americans should have unfettered access to the outdoors. Then the parking lots and the visitor centers started to fill up, worrying park employees.
