How to Save Rhinos? Make them Radioactive

Leave a reply

In a pioneering effort to combat wildlife trafficking of the threatened rhinoceros, a South African University began implementing a project supported by the International Atomic Energy Agency (IAEA). The project combines the safe insertion of radioactive isotopes into rhino horns… to deter and detect illegal poaching.

With over 10,000 rhinos lost to poaching in the past decade, South Africa – home to the world’s largest population of rhinos – remains a target for criminals driven by the illegal trade of rhino horn. In the first quarter of 2025 alone, the South African Ministry of Forestry, Fisheries and the Environment reported 103 rhinos poached. In response, this project run by the University of the Witwatersrand is using radiation to support conservation and enforcement efforts.

The Rhisotope Project was created in 2021 with the idea to tag rhino horns with radioactive material. This makes the horns detectable by radiation portal monitors (RPMs) already deployed at borders, ports and airports worldwide. These RPMs, commonly used to detect nuclear and other radioactive material, can now be harnessed against wildlife crime.

Colossal Efforts to Bring Back Species on the Brink of Extinction

Leave a reply

Colossal Biosciences, the world’s first de-extinction company, announced on October 1, 2024 the formation of The Colossal Foundation…The Foundation is launching with three core programmatic focuses.

Saving today’s at-risk species: Colossal Foundation plans to build a model for integrating cutting-edge biotechnology with conservation efforts to bring back species that have been driven to the brink of extinction. The long term goal is to create a toolkit approach to simplify genetic rescue for conservationists. Initial projects include efforts focused on the Vaquita, Northern White and Sumatran Rhinos, Red Wolf, Northern Quoll, Ivory Billed Woodpecker, and Pink Pigeon.

R&D for Conservation: Colossal will partner to fund and deploy technologies that leverage artificial intelligence…Current projects include the Colossal drone-based anomaly detection system used by Save the Elephants, a vaquita acoustic monitoring program, and an AI-enabled orphaned elephant monitoring system leveraged by Elephant Havens in Botswana.

Ensuring Tomorrow’s Biodiversity: Developing a distributed genetic repository of species (a biobank) which can act as an insurance policy against unforeseen threats to biodiversity and provide a safety net for species facing extinction. The focus will be on those species closest to extinction to ensure their genetic diversity is not lost and the potential to bring them back, should the worst happen, remains. 

Vaquitas, a porpoise endemic to the Sea of Cortez/Gulf of California in Baja California, Mexico and the smallest of all living cetaceans, is on the brink of extinction. As of May 2023, only between 10 and 13 vaquitas remain. The loss of the vaquita could be a harbinger of further declines in the Gulf’s marine ecosystems, and the extinction of the vaquita would represent a cultural and symbolic loss. Colossal, in partnership with the Vaquita Monitoring Group and in support of the Mexican government’s La Comisión Nacional de Áreas Naturales Protegidas (CONANP) believes that there are low-impact technical solutions that can be used to safely biobank the existing animals while also helping to grow the vaquita population. …

Fewer than 80 Sumatran rhinos survive in tiny fragmented populations across the Indonesian islands of Sumatra and Borneo…Colossal Foundation will  supporting the Indonesian government’s work to breed Sumatran rhinos under their national conservation breeding program…in collaboration with Global Experts on the advance Assisted Reproductive Technology (a-ART) and Biobank program for the species…

The Colossal BioVault is an initiative, in partnership with Re:wild and others, to collect the primary materials needed to prevent extinction. By collecting tissue samples of the world’s most imperiled species in the Colossal BioVault, the Foundation intends to preserve and store biodiversity.

How to Save the Rhino: Fake Rhino Horns Flood the Market

Leave a reply

Rhinoceros horns are big business. Traditional Chinese medicine uses them to treat rheumatism and gout… And Yemeni craftsmen carve them into dagger handles. A kilogram can thus command as much as $60,000, so there is tremendous incentive for poachers to hunt the animals. Since almost all rhinoceros populations are endangered, several critically, this is a serious problem. Some conservationists therefore suggest that a way to reduce pressure on the animals might be to flood the market with fakes. This, they hope, would reduce the value of real horns and consequently the incentive to hunt rhinos.

That would require the fakes to be good. But Fritz Vollrath, a zoologist at Oxford University, reckons his skills as a forger are up to the challenge. As he writes in Scientific Reports, he and his colleagues from Fudan University, in Shanghai, have come up with a cheap and easy-to-make knock-off that is strikingly similar to the real thing.  The main ingredient of Dr Vollrath’s forged horns is horsehair. Despite their differing appearances, horses and rhinos are reasonably closely related. Horses do not have horns, of course. But, technically, neither do rhinos. Unlike the structures that adorn cattle and bison, which have cores made of bone, the “horns” of rhinoceros are composed of hairs bound tightly together by a mixture of dead cells.  Examination under a microscope showed that hairs collected from horses’ tails had similar dimensions and symmetry to those found in the horns of rhinos. 

The next task they tackled was making a suitable glue. This is made from a fibrous protein-rich glue of the sort produced naturally by spiders and silkworms. They bundled the treated horse hairs as tightly as they could in a matrix of this glue, and then left the bundles in an oven to dry.  The result was a material that, with some polishing, looked like rhino horn….DNA analysis would certainly reveal fakes, but such analysis is complicated and therefore hard to do in the sorts of back rooms in which rhino-horn sales tend to take place. The forgeries passed other tests with flying colors, though…
