Chester Zoo, @thetorontozoo.bsky.social and DublinZoo just announced a major partnership to advance conservation cryopreservation, which may be key to preserving the precious genetic diversity of threatened species.

Zoo representatives met at #iucncongress2025 to mark the agreement.

And also here are some worryingly vague answers right from the most moral military on earth's website re how "Swords of Iron War" aka IDF's cum retrieval units work
Who may submit a request for posthumous sperm retrieval The deceased's widow or regular partner does not usually have to submit a request to court, unless one or more of the deceased's relatives object to the procedure. A family court approval petition would be required in this instance. A family court must receive a request for approval from the deceased's parents or any other surviving family member. Hospitals have been directed to grant requests for posthumous sperm retrieval from the parents of the deceased throughout the Swords of Iron War, and for as long as there is a war, without referring them to a family court, provided that they understand that doing so may make it impossible to retrieve sperm given the amount of time that has passed since the deceased's passing, with the exception of situations in which the deceased's spouse or any other family member objects to the posthumous sperm retrieval or if the parents disagree. What is the procedure of posthumous sperm retrieval and preservation A medical specialist (either a urologist or a fertility specialist) removes parts of the testicular tissue and transfers them to a nearby laboratory in the In-Vitro Fertilization (IVF) Unit or in the Sperm Bank. In the laboratory, under a special microscope, the tissue is searched for living sperm cells. The sperm cells found or the testicular tissue are transferred for preservation in liquid nitrogen. What are the success rates of the posthumous retrieval of sperm for purposes of future progeny The success rates mostly depend on the time that passed from the moment of death and the retrieval of testicular tissue, the conditions in which the deceased was found before the retrieval of the tissue, the quality of the sperm before his death, and the circumstances of his death. In about 75% of all posthumous sperm retrievals performed up to 24 hours from the moment of death, it is possible to find living sperm cells suitable for cryopreservation. Future use of posthumously retrieved sperm will necessitate in-vitro fertilization (IVF). In these cases, the rates of fertilization, pregnancies and births achieved are significantly lower compared to cases of use of the sperm produced during the man's lifetime. When is it possible to use posthumously-retrieved sperm In accordance with the guidance by the Attorney General of Israel, the use of posthumously-retrieved sperm requires the approval of a family court. The family court shall review the deceased's wishes for progeny in light of the principle of respecting the deceased's will and a person's right over his body. In case of a request submitted by the woman who was the deceased's regular partner at the time of his death, it is reasonable to assume that the production of progeny from his partner, even if posthumously, is consistent with the deceased's will. The assumption shall remain effective as long as there are no indications that the deceased would have objected to this. In case of a request submitted by the deceased's parents, as at today, it is only possible to use the sperm if it can be proven that this was the deceased's will, and subject to the court's approval. Only a woman who is not related to the deceased may use the sperm, conceive, give birth and be the child's mother for all intents and purposes. If the deceased has objected to the posthumous use of his sperm, the use of his sperm will not be approved. Over the last few months, the Knesset's Health Committee discussed the "Motion for the Use of a Deceased Person's Sperm for Purposes of Progeny", having been approved on preliminary reading. The approval of the law may change the guidelines listed above.

This is not a particularly interesting article for most people.

But, as someone who has worked in cryopreservation with liquid nitrogen for 20 years, stories like this horrify me.

The lack of OHS safety precautions when working with such a dangerous material is criminally negligent.

Woman dies and another in hospital after cryotherapy session at Paris gym
Sources close to police inquiry say an employee collapsed after nitrogen leak and second woman is in intensive care Police in Paris have launched an investigation after a woman suffocated while undergoing a cryotherapy session at a city gym and a second was taken to intensive care. The dead woman, a 29-year-old employee of the gym, collapsed after a nitrogen leak from a cold chamber that had been repaired earlier in the day, sources close to the inquiry said. The colourless and odourless gas is used to create an atmosphere of extreme subzero temperatures. Continue reading...

Embryos can be frozen past 4 weeks. Embryo freezing, also known as embryo cryopreservation, is a common practice in assisted reproductive technology (ART). Embryos can be frozen at different stages of development.

Know why you can freeze embryos, but not babies?

Bcuz embryos AREN'T HUMAN BEINGS.
