The rarest and rarest feline on the planet has found the nail in the coffin that was missing: the war in Iran

He asian cheetah (Acinonyx jubatus venaticus) is one of the rarest and most endangered subspecies of big cats on the planet. There are only 27 individuals left at large, all of them are identified one by one and all of them live in Iran, as explains Bagher Nezaminational director of Asiatic Cheetah Conservation Project. There is no other known population anywhere else on the planet. In serious danger of extinction, what was already a critical situation has become an emergency since the attacks by the United States and Israel in Iran began in February 2026: the war has paralyzed the only monitoring system that kept this subspecies under control. What is happening with the Asian cheetah. As account the environmental science and conservation news platform Mongabay, just nine days after forest guards filmed a female with five cubs in the province of North Khorasan, the armed conflict began. Since then, access to the reserves where these animals live has been drastically restricted. The risk is not so much that a bomb falls on a reserve, but rather the lack of vigilance. The field vehicles used by field scientists and park rangers to guard the small population of Asiatic cheetahs can be mistaken for military targets in their scattered habitat (especially in the desert), so many of Iran’s environmental NGOs have stopped their activity. The country also suffers an internet blackout. This means that monitoring, field studies and field use are no longer operational. The species. The Asian cheetah diverged from African populations between 32,000 and 67,000 years ago. It is not an African cheetah implanted in Asia, but rather it has its own evolutionary lineage: it is smaller and has lighter fur than the African one and is adapted to arid areas and mountainous terrain. In fact, its monitoring is more complex not only because there are few of them, but because it lives in inhospitable areas. In any case, both are true Ferraris: they can exceed speeds of 100 km/h in short races. The IUCN has it classified on the Critically Endangered conservation scale since 1996, the highest alert before extinction in the wild. From an ecological perspective, it serves as a specialized predator on medium-sized ungulates—mainly gazelles—in the desert ecosystems of central Iran. Their disappearance could not be compensated by introducing African cheetahs: the genetic, physiological and behavioral divergence between both groups is too great and hybridization proposals do not have scientific support as a viable short-term solution. Why is it important. Because it is not a rare subspecies of a known felid, but rather it has a genetically differentiated lineage and is native to Asia. It has more than 30,000 years of history independent of African populations and its disappearance is not compensated by introducing African cheetahs. Furthermore, it fulfills its function there: it is a specialized predator on medium-sized ungulates in the arid ecosystems of central Iran, thus maintaining the balance of gazelle populations. In short: it has its place in the food chain of the desert ecosystem in the interior of the country. The situation of the Asian cheetah is also a direct indicator of the state of biodiversity conservation at war, as pointed out this article in People and Nature: its consequences are suffered decades after the conflict and sometimes, they are simply irreversible. Iran is home to exceptional biological diversity: Persian leopard, brown bear (Ursus arctos), Eurasian lynx (Lynx lynx), gray wolf (Canis lupus), among others. The collapse of the cheetah conservation system irremediably affects the rest. Context. Since 1959, the Asiatic cheetah has had legal protection in Iran. In the following decades its population was stabilized, but the Revolution of 1979 and the Iran-Iraq war of the 1980s they were wasted years: Lax law enforcement wreaked havoc in the form of zero patrolling, destruction and fragmentation of their habitat, uncontrolled hunting, and decline in prey. In January 2022, Hassan Akbari, deputy minister of natural environment and biodiversity at Iran’s Department of Environment, declared that the Asiatic cheetah population had plummeted to just 12, down from an estimated 100 in 2010. In August 2025, the Tehran Times reported that only 20 copies remained. Monitoring them is very complicated per sebut there are also circumstances that work against it. For example, the controversial use of camera traps: in 2018 several people from Persian Wildlife Heritage Foundation accused of using camera traps for espionage. One person died in prison and the rest were pardoned in 2024. This case paralyzed international collaboration for years. In addition, Western sanctions have also systematically prevented the arrival of financing, essential for adequate monitoring. Asiatic cheetah dies. The main cause of death for Asian cheetahs is not poaching or predators, but the road. More than 52% of documented deaths They are due to accidents on roads that cross or border key habitats and cheetahs cross them without fear and repeatedly following their prey, such as Abbasabad-Mashhad and Mehriz-Anar. There are a couple of especially notorious cases of females run over, pregnant or with their young, in recent years: Meyami and Helia. Since the beginning of the conflict, these roads now also transport military material and people for evacuation, which increases traffic. With 27 individuals registered, there is no longer room for errors or unsupervised times: genetic analysis published in Conservation Genetics details that genetic diversity is critically low and inbreeding poses an additional risk to the viability of the subspecies. What can be done. Wild Tomorrow analyzes this problem in detail, advising to ignore social media campaigns that call for “emergency evacuations” without rigor: moving big wild cats across militarized borders is medically risky and informal channels can prove to be a route for illegal trafficking. Furthermore, we have already seen that proposing clandestine communications can expose those who protect the cheetah to accusations of espionage. What does have a real effect is supporting the Iranian Cheetah Society, the organization with the greatest field knowledge of this population. Likewise, at the international level there are organizations with real capacity … Read more

The rarest chicken in Spain is blue and lives in Extremadura. What we don’t know is for how long

Human beings are ungrateful animals. For decades, while we miserably worked the land, those blue chickens (rustic, tough and independent) were very good for us. The battered farmhouses of Extremadura, toasted by the sun, extractivism and simple life, were full of them. But then modernity, cities and supermarkets came… and they became a hindrance. Today, despite the fact that in recent years the institutions have stepped up, there will be about 2,000 chicken specimens Extremaduran blue. The Extremadura Blue Hen Breeders Association has 23 farms, but most people raise them for personal consumption or as a simple hobby. It is the rarest chicken in Spain and that, believe me, is saying a lot. A country without half measures. In Spain there are 21 poultry breeds in danger of extinction. This means that 95.4% of all registered native poultry breeds are threatened. In fact, 84% of all native breeds (whether they are birds or not) are in danger. And it is curious because, in short, we live in an unparalleled agricultural power. Spain is the second largest chicken producer of the European continent (only behind the United Kingdom), the third in beef and the first in pork (although swine fever can change this). Although, to tell the truth, it is not that curious. In fact, that is the problem. The emergence of industrial poultry farming since the 50s it was cornering local breeds for the benefit of commercial hybrids specialized in pure and simple production. Therefore, deep down, we are not talking about a problem of great economic magnitude. We are talking about two central issues in the present and the future of the ‘Spain emptied‘: the territorial management model and the question of what we do with genetic heritage. Since its recovery began in 1991 (when only specimens were found in five towns in the region), the situation has improved greatly. But not enough: all those questions are still on the table. And they are not easy questions to answer. Because, and in this case the blue Extremaduran hen, is a good example of the problems that arise as soon as we start working on the matter. because the underlying question is whether a livestock breed can be preserved if no one can make a living from it. And not only because the regulations They are designed for industrial poultry farming (and represents a very considerable obstacle), but for the paradox that hides in a simple Extremadura hen: the realization that not even at the time with greater institutional support (MAPA logo, breeding programs, germplasm banks, etc…) this breed can take its commercial leap. Is it a warning to sailors? Is it the future we have to live?

The rarest element on Earth aims to cure cancer. And Europe is already accelerating its production

In the fight against cancer there are many ‘weapons’ that we have at our disposalsuch as chemotherapy or radiotherapy. The problem is that these are assimilated like bombing a city to destroy a single house: it is achieved, but with a lot of collateral damage. But this can be solved if We attack only what interests usin this case a tumor cell, and science points to one of the rarest elements on the planet as a candidate to achieve this. Where are we now. The goal of science is to find the most specific therapies possible so that they attack a tumor cell and not a healthy cell with the aim of reducing the adverse effects of the treatment and also being more effective. For this there are different options such as immunotherapy or the use of very specific antibodies, but there is still a long way to go. A particle. He astatinewhose name comes from the Greek astats (“unstable”), lives up to its name. It is the rarest natural element on Earth and disappears almost as soon as it is formed and that is very interesting to us. Especially a ‘version’ of this element which is At-211 which has a half-life of only 7.2 hours. But this instability is part of its magic. At-211 is what Texas A&M scientists call a “Goldilocks” isotope: perfect for the job. Its advantages. Currently, heto traditional radiation used in cancer treatments have a great impact on the body when traveling over long distances. But At-211 emits alpha particles, which is a heavy, slow-moving helium nucleus, which when emitted releases an enormous amount of energy, but can only travel a tiny distance, just the thickness of a few cells. This is crucial. Targeted Alpha Therapy involves “gluing” an atom of At-211 to a molecule (such as an antibody) designed to specifically seek out and bind to cancer cells. At-211 travels through the body, ignoring healthy cells, and when it finds its target, it anchors to the tumor and releases its alpha particle. The result is a localized and devastating explosion of energy, which irreversibly destroys the DNA of the cancer cell. But since the particle cannot travel any further, the healthy cell next to it will not be affected, making this an almost perfect killer. Your problem. At first glance everything seems great, but… Why don’t we use it? The answer lies in its availability, since it is impossible to mine astatine, since with a life of 7.2 hours the clock is running against it. The only way to obtain it is to create it artificially in a cyclotron, a particle accelerator. The process basically involves firing a beam of alpha particles at a Bismuth-209 target. Now the advance that has been achieved is to create a fully automated system to produce and ship the AT-211 as quickly as possible so that it can be used. In Europe. With this advance, which has been made in Texas, processing time is reduced and the safety of technicians who do not have to handle this substance increases. And while Texas A&M resolves supply in the US, Europe is making a move. The project Accelerate.EUfunded by the European Union, was launched at the end of 2024 with a clear objective: to create a robust and sustainable manufacturing and treatment infrastructure for At-211 throughout Europe. The project focuses on especially difficult-to-treat cancers, such as pancreas, breast and brain tumors (glioblastomas), demonstrating that this therapy is a global strategic priority. The future therefore lies in the possibility of using one isotope to illuminate the tumor and then using another to kill it, inaugurating authentic personalized nuclear medicine.
