sick offspring ask to be executed to save the colony

In nature, the survival instinct It is usually the absolute norm: any living being fights to stay alive until the last second. However, in the world of social insects the rules change radically, as happens with ants, which When they get sick they actively ask to be euthanized so as not to condemn the rest of his colony. As if it were some kind of euthanasia. The smell of death. Until now, it was known that sick animals in groups often hid their symptoms to avoid being excluded or attacked by someone more powerful in the herd. But in ant colonies, where everyone is closely related, the logic is completely reversed. According to a published study in Nature and after analyzing invasive garden ants, it has been seen that ant pupae infected by pathogenic fungus Metarhizium brunneum They do not passively wait to die. On the contrary, when the infection is fatal and they know there is no other remedy, they modify their body chemistry to alert the workers. Something complex. Although they do not speak (or at least we do not understand them) ants have a communication system between them. In this case they do it through chemical signals based on cutillary hydrocarbonswhich we could say is a smell that the ant gives off. In this way, by activating a series of reactions when they see that their death is near, a greater amount of this hydrocarbon ends up being generated, which results in a warning to the rest of the ants warning “I am a biological threat.” A ‘kill me’ warning. Upon detecting this signal, the worker ants do not attempt to cure the pupa. The answer is destructive unpacking and disinfection: they remove the pupa from its cocoon prematurely, bite it, and inject it with acid (poison) to kill it and sterilize the fungus before it can sporular and infect the entire colony. In this way, we are seeing that ants are true heroes because they sacrifice their lives thinking about the entire colony. There is one exception. Death with this system is something that has been seen exclusively in worker pupae. By this we mean that those pupae that are predestined to become future queens do not emit these death signals, even when they are infected. So… Is this an act of real selfishness? The answer seems no. The immunological analysis revealed that queen pupae They have a basal immune system that is 35% more powerful than that of workers. While the workers succumb to the replication of the fungus, the queens are able to contain the infection on their own and that is why they are not a threat to the entire group of ants and therefore do not need to ask for sacrifice. New evidence. This discovery reinforces a fascinating theory in biology: social immunity. In the same way that the cells in your body have mechanisms to self-destruct with apoptosis if they become cancerous or infected by a virus to save the entire organism, individual ants act as cells of a larger body. The study concludes that this sacrifice is not an act of submission, but rather a finely tuned evolutionary adaptation. The chemical signal does not simply indicate “I am sick” (which could lead to an attempt at a cure), but rather it indicates “I have failed to overcome the infection and am a danger.” Images | Prince Patel In Xataka | New species of insects are not discovered in exotic places: we have just found two new ants in Andalusia

In 1521 Spain established a timid colony on the island of Borneo. Today they demand 15,500 million euros for it

In a corner of Southeast Asia, the island of Borneo has been the scene of a historical entanglement that seems like something out of a novel. What began more than a century ago as a trade agreement between a local sultan and European businessmen today translates into multimillion-dollar lawsuits and international arbitrations involving Spain, Malaysia and the descendants of the Joló sultanate. The surprising thing is that the origin of all this mess goes back to a detail that many would overlook, but given that when it happened the island was under Spanish jurisdiction, a century and a half later, the judicial imbroglio has spilled over into a Spain that has been involved in a lawsuit for 15.5 billion euros without a hitch. Signing of the agreement and colonial movements In 1878, the island of Borneo was under Spanish administration in certain areas, although real authority corresponded to the Sultan of Joló, the highest authority in a small Muslim kingdom located to the north of that island. In that year, Sultan Jamalul Alam signed an agreement with two British businessmen, Baron of Overbeck and Alfred Dent for the exploitation of natural resources of the area. However, for the descendants of the sultan, that contract had a lease character, while for the British it implied a definitive transfer. First point of disagreement. Spain, as the administrative power of the time, left evidence of its limits and neither punctured nor cut nor cut in that agreement. Reproduction of the 1878 agreement In 1885 the Madrid Protocol between the United Kingdom, Germany and Spain, with which Spain formally renounced any right over Borneo and recognized British control of the area, left in hands of the British North Borneo Company to its colonial exploitation and became part of the British colonial territories. Already in 1963, the island of Borneo was integrated in the newly formed Malaysia, and the Joló sultanate was integrated as the state of Sabah. Under the agreement signed in 1878, the Malaysian government was the “heir” of that transfer/lease of the territory, so kept a symbolic payment annual payment of about 5,300 ringgit (about 1,110 euros per year at the exchange rate) to the sultan’s heirs. However, in the 1980s and 1990s, oil and gas deposits were discovered in that territory, so Malaysia, through the company Petronas. With a treasure of such magnitude under the soil of their territory and with a difference of opinion regarding the meaning of the initial agreement, the heirs of Sultan of Joló began to pressure Malaysia to return their lands. Something that Malaysia rejected outright. Invasion of Sabah and start of battle Everything changed in 2013, when a group of 235 linked to the heirs of the Sultan of Joló invaded Sabah, starting what became known as the Lahad Datu conflictclaiming the sovereignty of the region. Malaysia responded with military force and stopped the rebels declaring that the state of Sabah was part of the sovereignty of Malaysia. In retaliation, he decided to suspend historic payments to the sultan’s descendants. This suspension marked the beginning of a long international legal dispute since now the heirs did not have the right of ownership of the lands nor did Malaysia recognize the agreement signed in 1878. Since in 1878 the kingdom of Sabah was under the administrative control of Spain, the sultan’s heirs considered that the historical jurisdiction belonged to Spain and requested arbitration in Spain, trusting that the country’s courts could act as a neutral venue to resolve the conflict between Malaysia and the heirs of the Sultan of Joló. Territory in dispute From trade disagreement to billion-dollar international conflict In 2019 and already in Spain, the Superior Court of Justice of Madrid (TSJM) assigned arbitration in principle to lawyer Gonzalo Stampa. However, in 2020 and after studying the case in more detail, the same court ordered arbitrator Stampa to stop the arbitration by determining that the State of Malaysia could not be judged by another State. Despite the disqualification and orders from the Spanish justice system, Stampa ignored it and continued with the mediation process. Since it had been banned in Spain, Stampa moved the arbitration to Paris and, in 2022, he dictated a favorable award to the heirs of the sultan. In the award issued by Stampa, which we remember at that time was “free” and no longer recognized by Spain, it could be read: “(…) the Arbitrator decides that the Claimants have the right to recover from the Respondent the restitution value of the rights over the leased territory in northern Borneo. (…) and orders the Respondent to pay the Claimants the sum of 14.92 billion US dollars.” Painting of the Sultan from the late 19th century That is to say, not only had he ignored the instructions of the Spanish justice system, but he also condemned Malaysia to pay compensation of 15,000 million dollars to the heirs. Obviously, nor Malaysia neither Spain nor even Paris Court of Appeal and then the Cour de Cassation French recognized the nullity of the arbitration. In fact, the Supreme Court recently condemned to referee Stampa for contempt and usurpation of functions. Although no authority recognized this arbitration, the heirs attempted to enforce the award by confiscating Malaysian assets, in the form of Petronas assets, in Holland and Luxembourgbut European courts temporarily stayed the action. At the same time, the heirs of the Sultan of Joló filed a new complaint against Spain claiming 15.5 billion euros, alleging that the country had hindered the execution of the award. This demand has just been dismissed by the ICSID (International Center for Settlement of Investment Disputes) tribunal dependent on the World Bank, which considered that there was no “protected investment” and ordered the heirs to assume the costs of the procedure. The result is that Spain leaves the dispute without paying a single euro, while the legal battle for territory and compensation against Malaysia remains open and on multiple fronts in Europe and Asia.
