Northern White Rhino Eggs Successfully Fertilized

26.08.2019

After successfully harvesting 10 eggs from the world’s last two northern white rhinos, Najin and Fatu, on August 22nd in Kenya, the international consortium of scientists and conservationists announces that 7 out of the 10 eggs (4 from Fatu and 3 from Najin) were successfully matured and artificially inseminated. This was achieved through ICSI (Intra Cytoplasm Sperm Injection) with frozen sperm from two different northern white rhino bulls, Suni and Saut, on Sunday, August 25th. This is the next critical step in hopefully creating viable embryos that can be frozen and then later on transferred to southern white rhino surrogate mothers.

“We were surprised by the high rate of maturation achieved as we do not get such high rate (comparable to what we get with horse oocytes) with southern white rhino females in European zoos.

The semen of Saut was very difficult to work with and to find three live sperms needed for the eggs of Najin we had to thaw two batches of semen.

Now the injected oocytes are incubated and we need to wait to see if any viable embryo develop to the stage where it can be cryopreserved for later transfer,” said Cesare Galli of Avantea in Cremona (Italy) who led the fertilization procedure.

The international research consortium to save the northern white rhino from extinction is led by Thomas Hildebrandt from the Leibniz Institute for Zoo and Wildlife Research (IZW).

Avantea is responsible for maturing the egg cells and creating viable embryos, further key project partners are Dvůr Králové Zoo, Ol Pejeta Conservancy and the Kenya Wildlife Service.

The results of possible embryo development are to be announced around September 10th.
The research program (BioRescue) is funded by the German Federal Ministry of Education and Research (BMBF).

Im Focus: Harnessing the rain for hydrovoltaics

Drops of water falling on or sliding over surfaces may leave behind traces of electrical charge, causing the drops to charge themselves. Scientists at the Max Planck Institute for Polymer Research (MPI-P) in Mainz have now begun a detailed investigation into this phenomenon that accompanies us in every-day life. They developed a method to quantify the charge generation and additionally created a theoretical model to aid understanding. According to the scientists, the observed effect could be a source of generated power and an important building block for understanding frictional electricity.

Water drops sliding over non-conducting surfaces can be found everywhere in our lives: From the dripping of a coffee machine, to a rinse in the shower, to an...

Im Focus: Blocking the Iron Transport Could Stop Tuberculosis

The bacteria that cause tuberculosis need iron to survive. Researchers at the University of Zurich have now solved the first detailed structure of the transport protein responsible for the iron supply. When the iron transport into the bacteria is inhibited, the pathogen can no longer grow. This opens novel ways to develop targeted tuberculosis drugs.

One of the most devastating pathogens that lives inside human cells is Mycobacterium tuberculosis, the bacillus that causes tuberculosis. According to the...

Im Focus: Physicist from Hannover Develops New Photon Source for Tap-proof Communication

An international team with the participation of Prof. Dr. Michael Kues from the Cluster of Excellence PhoenixD at Leibniz University Hannover has developed a new method for generating quantum-entangled photons in a spectral range of light that was previously inaccessible. The discovery can make the encryption of satellite-based communications much more secure in the future.

A 15-member research team from the UK, Germany and Japan has developed a new method for generating and detecting quantum-entangled photons at a wavelength of...

Im Focus: Junior scientists at the University of Rostock invent a funnel for light

Together with their colleagues from the University of Würzburg, physicists from the group of Professor Alexander Szameit at the University of Rostock have devised a “funnel” for photons. Their discovery was recently published in the renowned journal Science and holds great promise for novel ultra-sensitive detectors as well as innovative applications in telecommunications and information processing.

The quantum-optical properties of light and its interaction with matter has fascinated the Rostock professor Alexander Szameit since College.
