Scientists in Europe said Tuesday they've successfully transferred a test tube rhino embryo back into a female whose eggs were fertilized in vitro, as part of an effort to save another nearly extinct sub-species of the giant horned mammal.
The procedure was performed last month on a southern white rhino at Chorzow zoo in Poland, said Thomas Hildebrandt of the Leibniz Institute for Zoo and Wildlife Research in Berlin.
Hildebrandt is part of BioRescue, an international team of scientists and conservationists trying to use IVF to save the rare northern white rhino.

Only two northern white rhinos — both females — are left. The last male northern white rhino, named Sudan, died in March 2018. Scientists had preserved frozen sperm samples from several males that they now hope to use to revive the species.
Scientists chose to test the IVF transfer on southern white rhinos, a closely related sub-species whose numbers have stabilized in the wild.
"This is the first positive proof that the entire procedure we've developed in theory can be successful," Hildebrandt told reporters in Berlin.
But time is running out.
The BioRescue team is waiting for permission from the Kenyan government to harvest eggs from the last two surviving female northern white rhinos, a mother and daughter called Najin and Fatu. They are unable to bear offspring themselves, so once the embryos are fertilized in the lab they would be implanted in a southern white rhino surrogate mother.
Kenya's ambassador in Germany, Joseph Magutt, said his country supports the effort, but didn't say how long it would take to clear the paperwork.
Hildebrandt cautioned that while ultrasound tests show the embryo transferred at Chorzow zoo has grown, it's smaller than expected and it remains to be seen whether it will implant in the mother's uterine lining and result in a pregnancy.
"There are a lot of technical problems that will be solved, but it will take time," said Cesare Galli, whose Italy-based company Avantea specializes in artificial reproduction of horses.
The German government announced Tuesday that it is supporting the project with 4 million euros ($4.6 million) funding.
In the meantime, others in the BioRescue team are working on ways to turn preserved skin cells from deceased rhinos into eggs or sperm, a procedure that's so far only been performed with mice.
Rhinos have long been under pressure from poachers because of their horns, and several sub-species are at risk of extinction. Conservationists say rhinos are important for the survival of many other species because of the role they play in landscaping their native habitat.
Earlier this week, five eastern black rhinos were transported from European zoos to Rwanda's Akagera National Park to help increase the genetic diversity of the rhino population there.
More broadly, a recent United Nations report warned that a million species are at risk of extinction in the coming decades, largely because of human activity.
PARIS (AP) —
Reuters photographer Mohammed Salem captured this year’s prestigious World Press Photo of the Year award Thursday with a depiction of loss and sorrow in Gaza, a heartrending photo of a Palestinian woman cradling the body of her young niece. The photograph, taken in Khan Younis just days after Salem’s own child was born, shows 36-year-old Inas Abu Maamar holding five-year-old Saly, who was killed along with her mother and sister when an Israeli missile struck their home.
Salem, who is Palestinian, described this photo filed Nov. 2 last year, as a “powerful and sad moment that sums up the broader sense of what was happening in the Gaza Strip.”
The image ”truly encapsulates this sense of impact,” said global jury chair Fiona Shields, The Guardian newspaper's head of photography. “It is incredibly moving to view and at the same time an argument for peace, which is extremely powerful when peace can sometimes feel like an unlikely fantasy,” she added.
The World Press Photo jury praised the shot’s sense of care and respect and its offering of a “metaphorical and literal glimpse into unimaginable loss.”
This is not the first time Salem has been recognized for his work on the Israeli-Palestinian conflict; he received a World Press Photo award more than a decade ago for another depiction of the human toll of conflict in the Gaza strip.
In the three other global categories announced Thursday, South Africa’s Lee-Ann Olwage won Photo Story of the Year for her touching series “Valim-babena,” featured in GEO magazine. The project focused on the stigmatization of dementia in Madagascar, a topic she explored through intimate portraits of “Dada Paul” and his family. Lack of public awareness surrounding dementia means that people displaying symptoms of memory loss are often stigmatized.
In the series, “Dada Paul,” who has lived with dementia for 11 years, is tenderly cared for by his daughter Fara. One of the standout images in the series shows him preparing for church with his granddaughter Odliatemix, capturing moments of normalcy and warmth amidst the challenges of dementia.
Photographer Alejandro Cegarra, a Venezuelan native who migrated to Mexico in 2017, won the Long-Term Project award for “The Two Walls,” published by The New York Times and Bloomberg. Cegarra’s project, initiated in 2018, examines a shift in Mexico’s immigration policies, which have moved from being historically open to enforcing strict regulations at its southern border. The jury said the photographer's perspective as a migrant gave it a “sensitive," human-centered perspective, according to a press release.
Julia Kochetova of Ukraine won the Open Format award for “War Is Personal.” The project stood out from coverage of the ongoing conflict by offering a personal look at the harsh realities of war. On a dedicated website, she merged traditional photojournalism with a diary-like documentary style, incorporating photography, poetry, audio clips and music.
The Associated Press won the Open Format award in the regional Africa category with the multimedia story “Adrift,” created by journalists Renata Brito and Felipe Dana. The story investigates the fate of West African migrants who attempted to reach Europe via a treacherous Atlantic route but ended up on a ghost ship discovered off Tobago. The team’s compelling use of photography, cinematography and detailed narrative, enhanced by expert design and multimedia elements, highlights the perils faced by migrants and the human stories behind global migration issues.
The Associated Press' Ebrahim Noroozi won the Asia Stories award for his series “Afghanistan on the Edge,” which documents the country since the Taliban took over in August 2021.
