One of the biggest navigation challenges is knowing where you are in the open ocean without tools or devices. This remarkable skill is exemplified by the ancient techniques once used by expert navigators of the Marshall Islands, a chain of
low-lying coral islands and atolls situated between Hawaii and the Philippines.

Together with a cognitive neuroscientist, philosopher, Marshallese anthropologist and two Indigenous sailors, I was part of a sailing expedition that aimed to explore how Marshallese sailors use their environment to find their way at sea. Aboard Stravaig, a 42ft (12m) trimaran (a boat with three hulls), the winds and waves carried us 60 miles from Majuro atoll to Aur atoll.

In the six years I lived in the Marshall Islands, I had never travelled past Eneko, a small islet within the lagoon of Majuro. I was always drawn to the reef where the lagoon meets the ocean, watching the white surf appear as the waves broke against the barrier that protected the atoll.

It was the knowledge of those waves that the ri meto (the person of the sea, a title given to a navigator by the chief), would dedicate their lives to mastering. By sensing subtle changes in ocean swells, the ri meto could detect the direction and distance to islands that lay thousands of miles beyond the horizon.

With this ancient knowledge, the ri meto mastered one of the most extraordinary skills known to humans: navigating the Pacific. But the devastating history of the Marshall Islands has extinguished the practice and currently, there is no officially appointed ri meto.

Alson Kelen is the apprentice of the last-known ri meto. His parents were displaced from the northern Bikini atoll during the US lead nuclear programme that detonated 67 atomic and thermonuclear bombs in the Marshall Islands during the 1940s and 50s.

Beyond the catastrophic destruction and suffering, it disrupted the inter-generational transfer of traditional knowledge, including navigation. As part of revival efforts by professor of anthropology Joseph Genz, Kelen captained the jitdaam kapeel, a traditional Marshallese canoe, from Majuro to Aur in 2015, relying solely on the traditional navigational skills he had learned as an apprentice.

Inspired by this, I was curious about the role that neuroscience played in understanding wayfinding at sea. Research in spatial navigation has revealed how the brain’s neural and cognitive processes help us find our way. Most of this research focuses on land-based navigation, either in lab settings or controlled environments using video games or virtual reality headsets. But the cognitive demands at sea are considerably greater with constantly changing factors, such as swells, winds, clouds and stars.

Neuroscience of navigation

As the director of Waan Aelon in Majel, a local canoe building and sailing school, Kelen chose two highly skilled traditional sailors to join us on our research expedition.

As we approached the channel, the steady waves of the lagoon gave way to the heavier ocean swells hitting the hull. The crew tightened the ropes and the sails were hoisted. All of a sudden, I felt the dominant eastern swell lift the boat. We had left the calm of the lagoon and were bound for Aur Atoll.

For the next two days, Stravaig was our lab on the ocean. For more than 40 hours we were collecting cognitive and physiological data from nine crew members, along with constant environmental data from our ever-changing surroundings.

We asked everyone to keep track of their estimated location throughout the voyage. Only two crew members (the captain and first mate) had access to GPS at intervals; others relied solely on the environment and memory. At hourly intervals, each crew member would mark their estimated position on a map, along with their predictions of how much time and distance remained till the first signs of land and eventually landfall itself. They also noted any environmental stimuli, such as the waves, winds or the position of the sun they were using.

The crew also rated four key emotions throughout the journey: happiness, tiredness, worry and seasickness. Each crew member wore an Empatica smartwatch, which recorded changes in their heart rate.

An accelerometer was mounted onto the top deck to record the movement of the boat as the wave patterns changed. A separate mounted 360° GoPro camera captured changes in the sails, clouds, sun, moon and movement of crew on deck.

Just before the last piece of land dipped under the horizon, each crew member pointed to five atolls: Jabwot, Ebeye, Erikub, Aur Tabal, Arno and Majuro. A covered compass was used to record the bearings. This was repeated across the journey to test orientation skills without reference to land.

By the end of this voyage, we had a rich collection of data that mixes subjective experiences with objective measurements of the environment. Every estimation plotted on a map, every emotion, every changing heart rate was recorded in conjunction with changes in wave patterns, the wind, the sky and the GPS beneath it all. This new data forms the foundation for a model that could begin to explain the cognitive process of wayfinding at sea, whilst also offering a glimpse into this ancient human ability, one that the ri meto mastered long ago.

Cuba’s leaders see their options dim amid blackouts and a shrinking economy

The lights went out in Cuba again.

For the fifth time in a year, all of Cuba plunged into darkness on Sept. 10, 2025. Even critical emergency services like hospitals suffered during the nearly 24-hour power outage.

That’s because Cuba’s power grid is old and hard to maintain, and the country cannot afford to import all the oil it needs to keep the lights on.

As a scholar of Cuban society and politics, I believe that the ongoing blackouts point to larger economic problems facing the country. While much of that is due to the continuing effects of the U.S. embargo, which since 1960 has obstructed American trade and tourism with the Caribbean island, Cuba’s leaders also deserve a share of the blame for their economic mismanagement.

Indeed, while other nominally communist countries, such as Vietnam and China, have facilitated the development of a private sphere in their economies in the past several decades, officials in Havana have in practice restricted such growth so as not to threaten state enterprises.

The result has been a less vibrant, less productive network of private enterprises unable to provide the economic growth that Cuba so desperately needs. All the while, Cuba’s communist government faces an existential threat as it struggles to maintain power in the face of popular discontent.

The external factors of the crisis

Since 2020, Cuba’s gross domestic product has shrunk by almost 11%, with economists forecasting a further decline of 1%-2% in 2025.

There are a number of reasons for this decline.

Tourism, Cuba’s lifeblood, has not rebounded since the COVID-19 pandemic. Meanwhile, Venezuela, which subsidized Cuba for a decade in the 2000s, particularly with oil exports, no longer has the capacity to do so. Further, persistent energy shortages in Cuba have led to steep declines in agricultural and industrial production.

From a broader perspective, the U.S. embargo also continues to harm the Cuban economy. For more than 60 years, Cubans have been unable to sell their products to the United States – and Americans have been unable to travel to or do business with Cuba outside of very limited categories.

Estimates vary as to what extent the embargo damages the Cuban economy, but it seems certain that the “blockade,” as Cubans call it, deprives the nation of at least hundreds of millions, if not billions, of U.S. dollars in trade every year, most particularly in agriculture and tourism.

Steps toward domestic reform

While external factors have taken a toll, the persistent economic difficulties facing Cubans are also self-inflicted by the government.

Cuba’s leaders have pursued a slow, narrow and sometimes arbitrary path toward economic privatization – especially when contrasted with other officially communist countries in Asia.

Following Fidel Castro’s departure from public life in 2008, Cuba’s subsequent leader, and Fidel’s brother, Raul Castro, announced a series of gradual steps intended to encourage private enterprise that had long been curtailed by the government.

Under Raul, the state allowed Cubans to own, buy and sell their homes; they could also create their own businesses, and even employ others to whom they were not related – practices prohibited under Fidel Castro.

The government also allowed more foreigners to invest in Cuba, principally in tourist infrastructure, provided they confined themselves to minority stakes.

Cubans were also permitted for the first time in decades to own their own land, grow food and sell it at markets, setting their own prices within limits. Collective farms, the bane of Soviet agriculture that had once inspired Fidel’s revolutionary visions, were no longer the norm.

By 2017, about 13% of the workforce held licenses to start businesses, while the private sector employed about one-third of all workers.

In the years immediately following these reforms, Cuba posted some gains in industrial and food production and GDP. Indeed, during the mid-2000s, Cuba posted impressive growth rates, sometimes in excess of 10%.

Domestic progress stalled

Unfortunately for Cubans, the upward trend did not continue.

And that is in no small measure due to Cuba’s prosperity in the 2000s being built on Venezuelan subsidies, not by Cuban entrepreneurs.

Venezuela’s late president, and longtime Castro admirer, Hugo Chavez, began to subsidize Fidel Castro’s government shortly after taking power in 1999.

A petrostate, Venezuela provided much-needed oil to Cuba on favorable terms, while also paying the Cuban nation for doctors to work in Venezuela’s hospitals and clinics, providing Cuba with the hard currency it needed to pay for imports.

Researchers estimate that the Venezuelan government subsidized the Cuban economy by as much as US$9 billion per year until 2016.

Venezuelan oil allowed Cuba to paper over a starker reality: Despite reforms, Cuba’s entrepreneurs remained hamstrung by a cumbersome and often corrupt state policy.

Thanks to ever-changing regulations, the majority of private businesses have remained small and dedicated to personal services, such as restaurants, hairdressing, seamstressing and repairs.

On a larger scale, Cuba’s state bureaucrats see competition with government-owned businesses, especially in tourism, as a threat to their power and privileges. Taxes also remain inequitably high for private firms.

Meanwhile, the larger private businesses that are now occasionally permitted are almost always, according to a number of my Cuban-based sources, connected to friends or family members of the political elite, not average Cubans.

There have been successes, to be sure. The private sector now accounts for more retail sales by volume than state enterprises.

But the percentage of the workforce employed by the private sector remains about what it was in 2019, while private enterprise accounts for only about 15% of Cuba’s GDP.

The unsustainable present

Confronting multiple crises, Cuba’s leaders continue to blame the U.S. embargo and policy from Washington that has become only more bellicose under President Donald Trump. No doubt drawing optimism from having weathered severe crises before, the Cuban government seems committed to a state of defiance.

But the evidence this time around suggests Havana’s leaders should be less sanguine.

Despite increasing costs, Cubans enjoy widespread access to [the internet] and they know just how bad and how inequitable things are.

For all the government’s rhetoric and commitment to a decades-old revolution, Cubans see a much-vaunted medical system that is failing, unable to provide drugs, procedures — or even electricity. They know that crime is on the rise, while inflation reduces the value of the Cuban peso relative to the dollar every week

Cubans see and hear of their well-connected countrymen, with links to state enterprises, flaunting their wealth. Cubans may also know that their military holds as much as US$18 billion abroad — about 16% of Cuba’s GDP in 2024.

What they certainly know and experience is the reality of being forced to live without power, with no possibility of improvement in sight.

Limited choices going forward

Historically, Cuba has been pulled from crises by foreign patrons willing to subsidize its revolution.

But Russia’s strategic position, China’s global priorities and Venezuela’s hardships all make that unlikely right now. And with the U.S. now pursuing a policy of maximum pressure against noncompliant governments in Latin America, Havana can rest assured that it will see little breathing room from its powerful neighbor and long-time antagonist.

That leaves the Cuban government with only a few options.

It could choose to continue trying to restrict its citizens’ access to the internet. Unfortunately for the state, the internet is the lifeblood of the private sector.

Cuba’s leaders could also choose to rely on the loyalty of its security forces and their ability to intimidate and abuse their fellow Cubans. That has worked in the past, but given Havana’s scarce resources and its limited capacity to reward its henchmen, it is not clear that the government can afford to adopt this approach indefinitely.

Of course, Cuba’s leaders could take steps toward further reform the private sector and eliminate the waste and corruption that have increasingly defined the Cuban state.

Such a course would require the government to permit all Cubans, not just a well-connected few, to compete with state enterprises. It would also mean allowing for a greater degree of foreign investment, which has remained stunted due to government policy.

If the past offers any guide, however, Havana will instead continue to rely on its formidable security apparatus to repress is citizens, while privatizing in ways that do not threaten the power and privileges of the elite.

Comment un médicament essentiel de la médecine moderne a été découvert sur l’île de Pâques

Source: The Conversation – France in French (3) – By Ted Powers, Professor of Molecular and Cellular Biology, University of California, Davis

Le peuple Rapa Nui est pratiquement absent de l’histoire de la découverte de la rapamycine telle qu’elle est généralement racontée. Posnov/Moment/Getty

La découverte en 1964, sur l’île de Pâques, de la rapamycine, un nouvel antibiotique, a marqué le début d’une success story pharmaceutique à plusieurs milliards de dollars. Pourtant, l’histoire a complètement occulté les individus et les dynamiques politiques qui ont rendu possible l’identification de ce « médicament miracle ».


Baptisé du nom autochtone de l’île, Rapa Nui, la rapamycine a initialement été employée comme immunosuppresseur, afin de prévenir le rejet des greffes d’organes et d’améliorer le taux de succès de l’implantation de stents, de petits treillis métalliques destinés à étayer les artères dans le cadre de la lutte contre la maladie coronarienne (laquelle se traduit par rétrécissement progressif des artères qui nourrissent le cœur, ndlr).

Son usage s’est depuis étendu au traitement de divers types de cancers, et les chercheurs explorent aujourd’hui son potentiel dans le contexte de la prise en charge du diabète,

des maladies neurodégénératives, voire de la lutte contre les méfaits du vieillissement. Ainsi, des études mettant en évidence la capacité de la rapamycine à prolonger la durée de vie ou à combattre les maladies liées à l’âge semblent paraître presque quotidiennement depuis quelque temps… Une requête sur PubMed, le moteur de recherche recense plus de 59 000 articles mentionnant la rapamycine. Il s’agit de l’un des médicaments qui fait le plus parler de lui dans le domaine médical.

Cependant, bien que la rapamycine soit omniprésente en science et en médecine, la façon dont elle a été découverte demeure largement méconnue du public. En tant que scientifique ayant consacré sa carrière à l’étude de ses effets sur les cellules, j’ai ressenti le besoin de mieux comprendre son histoire.

À ce titre, les travaux de l’historienne Jacalyn Duffin portant sur la Medical Expedition to Easter Island (METEI), une expédition scientifique mise sur pied dans les années 1960, ont complètement changé la manière dont nombre de mes collègues et moi-même envisageons désormais notre domaine de recherche.

La découverte du complexe héritage de la rapamycine soulève en effet d’importantes questions sur les biais systémiques qui existent dans le secteur de la recherche biomédicale, ainsi que sur la dette des entreprises pharmaceutiques envers les territoires autochtones d’où elles extraient leurs molécules phares.

Pourquoi un tel intérêt pour la rapamycine ?

L’action de la rapamycine s’explique par sa capacité à inhiber une protéine appelée target of rapamycin kinase, ou TOR. Cette dernière est l’un des principaux régulateurs de la croissance et du métabolisme cellulaires. De concert avec d’autres protéines partenaires, TOR contrôle la manière dont les cellules répondent aux nutriments, au stress et aux signaux environnementaux, influençant ainsi des processus majeurs tels que la synthèse protéique et la fonction immunitaire.

Compte tenu de son rôle central dans ces activités cellulaires fondamentales, il n’est guère surprenant qu’un dysfonctionnement de TOR puisse se traduire par la survenue de cancers, de troubles métaboliques ou de maladies liées à l’âge.

Un grand nombre des spécialistes du domaine savent que cette molécule a été isolée au milieu des années 1970 par des scientifiques travaillant au sein du laboratoire pharmaceutique Ayerst Research Laboratories, à partir d’un échantillon de sol contenant la bactérie Streptomyces hydroscopicus. Ce que l’on sait moins, c’est que cet échantillon a été prélevé dans le cadre d’une mission canadienne appelée Medical Expedition to Easter Island, ou METEI, menée à Rapa Nui – l’Île de Pâques – en 1964.

Histoire de la METEI

L’idée de la Medical Expedition to Easter Island (METEI) a germé au sein d’une équipe de scientifiques canadiens composée du chirurgien Stanley Skoryna et du bactériologiste Georges Nogrady. Leur objectif était de comprendre comment une population isolée s’adaptait au stress environnemental. Ils estimaient que la prévision de la construction d’un aéroport international sur l’île de Pâques offrait une occasion unique d’éclairer cette question. Selon eux, en accroissant les contacts de la population de l’île avec l’extérieur, l’aéroport risquait d’entraîner des changements dans sa santé et son bien-être.

Financée par l’Organisation mondiale de la santé, et soutenue logistiquement par la Marine royale canadienne, la METEI arriva à Rapa Nui en décembre 1964. Durant trois mois, l’équipe fit passer à la quasi-totalité des 1 000 habitants de l’île toute une batterie d’examens médicaux, collectant des échantillons biologiques et procédant à un inventaire systématique de la flore et de la faune insulaires.

Dans le cadre de ces travaux, Georges Nogrady recueillit plus de 200 échantillons de sol, dont l’un s’est avéré contenir la souche de bactéries Streptomyces productrice de rapamycine.

Il est important de comprendre que l’objectif premier de l’expédition était d’étudier le peuple de Rapa Nui, dans un contexte qui était vu comme celui d’un laboratoire à ciel ouvert. Pour encourager les habitants à participer, les chercheurs n’ont pas hésité à recourir à la corruption, leur offrant des cadeaux, de la nourriture et diverses fournitures. Ils ont également eu recours à la coercition : à cet effet, ils se sont assuré les services d’un prêtre franciscain en poste de longue date sur l’île pour les aider au recrutement. Si leurs intentions étaient peut-être honorables, il s’agit néanmoins là d’un exemple de colonialisme scientifique dans lequel une équipe d’enquêteurs blancs choisit d’étudier un groupe majoritairement non blanc sans son concours, ce qui crée un déséquilibre de pouvoir. Un biais inhérent à l’expédition existait donc dès la conception de la METEI.

Par ailleurs, plusieurs des hypothèses de départ avaient été formulées sur des bases erronées. D’une part, les chercheurs supposaient que les habitants de Rapa Nui avaient été relativement isolés du reste du monde, alors qu’il existait en réalité une longue histoire d’interactions avec des pays extérieurs, comme en témoignaient divers récits dont les plus anciens remontaient au début du XVIIIe siècle, et dont les publications s’étalaient jusqu’à la fin du XIXe siècle.

D’autre part, les organisateurs de la METEI partaient du postulat que le bagage génétique de la population de Rapa Nui était homogène, sans tenir compte de la complexe histoire de l’île en matière de migrations, d’esclavage et de maladies (certains habitants étaient en effet les descendants de survivants de la traite des esclaves africains qui furent renvoyés sur l’île et y apportèrent certaines maladies, dont la variole). La population moderne de Rapa Nui est en réalité métissée, issue à la fois d’ancêtres polynésiens, sud-américains, voire africains.

Cette erreur d’appréciation a sapé l’un des objectifs clés du METEI : évaluer l’influence de la génétique sur le risque de maladie. Si l’équipe a publié un certain nombre d’études décrivant la faune associée à Rapa Nui, son incapacité à établir une base de référence est probablement l’une des raisons pour lesquelles aucune étude de suivi n’a été menée après l’achèvement de l’aéroport de l’île de Pâques en 1967.

Rendre crédit à qui de droit

Les omissions qui existent dans les récits sur les origines de la rapamycine sont le reflet d’angles morts éthiques fréquemment présents dans la manière dont on se souvient des découvertes scientifiques.

Georges Nogrady rapporta de Rapa Nui des échantillons de sol, dont l’un parvint à Ayerst Research Laboratories. Là, Surendra Sehgal et son équipe isolèrent ce qui fut nommé rapamycine, qu’ils finirent par commercialiser à la fin des années 1990 en tant qu’immunosuppresseur, sous le nom Rapamune. Si l’on connaît bien l’obstination de Sehgal, qui fut déterminante pour mener à bien le projet en dépit des bouleversements qui agitaient à cette époque la société pharmaceutique pour laquelle il travaillait – il alla même jusqu’à dissimuler une culture de bactéries chez lui – ni Nogrady ni la METEI ne furent jamais crédités dans les principaux articles scientifiques qu’il publia.

Bien que la rapamycine ait généré des milliards de dollars de revenus, le peuple de Rapa Nui n’en a tiré aucun bénéfice financier à ce jour. Cela soulève des questions sur les droits des peuples autochtones ainsi que sur la biopiraterie (qui peut être définie comme « l’appropriation illégitime par un sujet, notamment par voie de propriété intellectuelle, parfois de façon illicite, de ressources naturelles, et/ou éventuellement de ressources culturelles en lien avec elles, au détriment d’un autre sujet », ndlr), autrement dit dans ce contexte la commercialisation de connaissances autochtones sans contrepartie.

Des accords tels que la Convention des Nations unies de 1992 sur la diversité biologique et la Déclaration de 2007 sur les droits des peuples autochtones visent à protéger les revendications autochtones sur les ressources biologiques, en incitant tous les pays à obtenir le consentement et la participation des populations concernées, et à prévoir des réparations pour les préjudices potentiels avant d’entreprendre des projets.

Ces principes n’étaient cependant pas en vigueur à l’époque du METEI.

Certaines personnes soutiennent que, puisque la bactérie productrice de rapamycine a été trouvée ailleurs que dans le sol de l’île de Pâques, ce dernier n’était ni unique ni essentiel à la découverte du médicament. D’autres avancent aussi qu’étant donné que les insulaires n’utilisaient pas la rapamycine et n’en connaissaient pas l’existence sur leur île, cette molécule ne constituait pas une ressource susceptible d’être « volée ».

Cependant, la découverte de la rapamycine à Rapa Nui a jeté les bases de l’ensemble des recherches et de la commercialisation ultérieures autour de cette molécule. Cela n’a été possible que parce que la population a été l’objet de l’étude montée par l’équipe canadienne. La reconnaissance formelle du rôle essentiel joué par les habitants de Rapa Nui dans la découverte de la rapamycine, ainsi que la sensibilisation du public à ce sujet, sont essentielles pour les indemniser à hauteur de leur contribution.

Ces dernières années, l’industrie pharmaceutique a commencé à reconnaître l’importance d’indemniser équitablement les contributions autochtones. Certaines sociétés se sont engagées à réinvestir dans les communautés d’où proviennent les précieux produits naturels qu’elles exploitent.

Toutefois, s’agissant des Rapa Nui, les entreprises qui ont directement tiré profit de la rapamycine n’ont pas encore fait un tel geste.

Si la découverte de la rapamycine a sans conteste transformé la médecine, il est plus complexe d’évaluer les conséquences pour le peuple de Rapa Nui de l’expédition METEI. En définitive, son histoire est à la fois celle d’un triomphe scientifique et d’ambiguïtés sociales.

Je suis convaincu que les questions qu’elle soulève (consentement biomédical, colonialisme scientifique et occultation de certaines contributions) doivent nous faire prendre conscience qu’il est nécessaire d’examiner de façon plus critique qu’ils ne l’ont été jusqu’à présent les héritages des découvertes scientifiques majeures.

Il est important de comprendre que l’objectif premier de l’expédition était d’étudier le peuple de Rapa Nui, dans un contexte qui était vu comme celui d’un laboratoire à ciel ouvert. Pour encourager les habitants à participer, les chercheurs n’ont pas hésité à recourir à la corruption, leur offrant des cadeaux, de la nourriture et diverses fournitures. Ils ont également eu recours à la coercition : à cet effet, ils se sont assuré les services d’un prêtre franciscain en poste de longue date sur l’île pour les aider au recrutement. Si leurs intentions étaient peut-être honorables, il s’agit néanmoins là d’un exemple de colonialisme scientifique dans lequel une équipe d’enquêteurs blancs choisit d’étudier un groupe majoritairement non blanc sans son concours, ce qui crée un déséquilibre de pouvoir. Un biais inhérent à l’expédition existait donc dès la conception de la METEI.

Par ailleurs, plusieurs des hypothèses de départ avaient été formulées sur des bases erronées. D’une part, les chercheurs supposaient que les habitants de Rapa Nui avaient été relativement isolés du reste du monde, alors qu’il existait en réalité une longue histoire d’interactions avec des pays extérieurs, comme en témoignaient divers récits dont les plus anciens remontaient au début du XVIIIe siècle, et dont les publications s’étalaient jusqu’à la fin du XIXe siècle.

D’autre part, les organisateurs de la METEI partaient du postulat que le bagage génétique de la population de Rapa Nui était homogène, sans tenir compte de la complexe histoire de l’île en matière de migrations, d’esclavage et de maladies (certains habitants étaient en effet les descendants de survivants de la traite des esclaves africains qui furent renvoyés sur l’île et y apportèrent certaines maladies, dont la variole). La population moderne de Rapa Nui est en réalité métissée, issue à la fois d’ancêtres polynésiens, sud-américains, voire africains.

Cette erreur d’appréciation a sapé l’un des objectifs clés du METEI : évaluer l’influence de la génétique sur le risque de maladie. Si l’équipe a publié un certain nombre d’études décrivant la faune associée à Rapa Nui, son incapacité à établir une base de référence est probablement l’une des raisons pour lesquelles aucune étude de suivi n’a été menée après l’achèvement de l’aéroport de l’île de Pâques en 1967.

Rendre crédit à qui de droit

Les omissions qui existent dans les récits sur les origines de la rapamycine sont le reflet d’angles morts éthiques fréquemment présents dans la manière dont on se souvient des découvertes scientifiques.

Georges Nogrady rapporta de Rapa Nui des échantillons de sol, dont l’un parvint à Ayerst Research Laboratories. Là, Surendra Sehgal et son équipe isolèrent ce qui fut nommé rapamycine, qu’ils finirent par commercialiser à la fin des années 1990 en tant qu’immunosuppresseur, sous le nom Rapamune. Si l’on connaît bien l’obstination de Sehgal, qui fut déterminante pour mener à bien le projet en dépit des bouleversements qui agitaient à cette époque la société pharmaceutique pour laquelle il travaillait – il alla même jusqu’à dissimuler une culture de bactéries chez lui – ni Nogrady ni la METEI ne furent jamais crédités dans les principaux articles scientifiques qu’il publia.

Bien que la rapamycine ait généré des milliards de dollars de revenus, le peuple de Rapa Nui n’en a tiré aucun bénéfice financier à ce jour. Cela soulève des questions sur les droits des peuples autochtones ainsi que sur la biopiraterie (qui peut être définie comme « l’appropriation illégitime par un sujet, notamment par voie de propriété intellectuelle, parfois de façon illicite, de ressources naturelles, et/ou éventuellement de ressources culturelles en lien avec elles, au détriment d’un autre sujet », ndlr), autrement dit dans ce contexte la commercialisation de connaissances autochtones sans contrepartie.

Des accords tels que la Convention des Nations unies de 1992 sur la diversité biologique et la Déclaration de 2007 sur les droits des peuples autochtones visent à protéger les revendications autochtones sur les ressources biologiques, en incitant tous les pays à obtenir le consentement et la participation des populations concernées, et à prévoir des réparations pour les préjudices potentiels avant d’entreprendre des projets.

Ces principes n’étaient cependant pas en vigueur à l’époque du METEI.

Certaines personnes soutiennent que, puisque la bactérie productrice de rapamycine a été trouvée ailleurs que dans le sol de l’île de Pâques, ce dernier n’était ni unique ni essentiel à la découverte du médicament. D’autres avancent aussi qu’étant donné que les insulaires n’utilisaient pas la rapamycine et n’en connaissaient pas l’existence sur leur île, cette molécule ne constituait pas une ressource susceptible d’être « volée ».

Cependant, la découverte de la rapamycine à Rapa Nui a jeté les bases de l’ensemble des recherches et de la commercialisation ultérieures autour de cette molécule. Cela n’a été possible que parce que la population a été l’objet de l’étude montée par l’équipe canadienne. La reconnaissance formelle du rôle essentiel joué par les habitants de Rapa Nui dans la découverte de la rapamycine, ainsi que la sensibilisation du public à ce sujet, sont essentielles pour les indemniser à hauteur de leur contribution.

Ces dernières années, l’industrie pharmaceutique a commencé à reconnaître l’importance d’indemniser équitablement les contributions autochtones. Certaines sociétés se sont engagées à réinvestir dans les communautés d’où proviennent les précieux produits naturels qu’elles exploitent.

Toutefois, s’agissant des Rapa Nui, les entreprises qui ont directement tiré profit de la rapamycine n’ont pas encore fait un tel geste.

Si la découverte de la rapamycine a sans conteste transformé la médecine, il est plus complexe d’évaluer les conséquences pour le peuple de Rapa Nui de l’expédition METEI. En définitive, son histoire est à la fois celle d’un triomphe scientifique et d’ambiguïtés sociales.

Je suis convaincu que les questions qu’elle soulève (consentement biomédical, colonialisme scientifique et occultation de certaines contributions) doivent nous faire prendre conscience qu’il est nécessaire d’examiner de façon plus critique qu’ils ne l’ont été jusqu’à présent les héritages des découvertes scientifiques majeures.

Why coral reefs damaged by blast fishing struggle to recover — even after decades

Source: The Conversation – Indonesia – By Satrio Hani Samudra, Data Manager, UCL

When we think about rapid decline in coral reefs, climate change often first that comes to mind — bringing heatwaves, bleaching events, and intensified cyclones.

But in parts of Indonesia, an old, lasting wound still lingers beneath the waves — inflicted not just by warming seas, but also by explosives.

Blast fishing — where fishers hurl homemade bombs made from fertiliser and kerosene into the sea — is still being used.

This illegal fishing method kills fish instantly for easy collection. As an shattering coral reefs into rubble and wiping out entire reef communities within seconds.

Unlike a fallen tree that can grow back, our research shows that a reef shattered into fragments usually cannot — and may remain damaged for decades.

Rubble that refuses to rest

At first glance, rubble might seem like a natural stage of reef recovery. Storms and cyclones can also break corals into fragments that sometimes stabilise and form a foundation for new coral growth. But rubble from blast fishing is different.

The explosions break corals into much smaller pieces — usually less than 10 cm long. These fragments are light, unstable, and easily swept around by everyday waves and currents. It’s like trying to build a house on marbles instead of bricks: every time you add a piece, the foundation shifts beneath it.

In our surveys across Bunaken National Park in North Sulawesi, we found fewer than 10% of coral fragments stable. Even organisms that typically help “glue” rubble together, such as coralline algae and sponges, were rare. Without stability, young corals struggle to survive — often buried, overturned, or scraped away.

Mixed outcomes from early restoration efforts

One of our study sites underwent “restoration” back in 2003, using ceramic dome-like structures known as EcoReefs. These modules were designed to mimic coral branches, slow currents, and give rubble a chance to stabilise.

Two decades later, the results were underwhelming. Many modules had been overturned or buried, and although some supported coral growth, overall coral cover remained extremely low. In fact, the restored site fared no better than nearby unrestored areas.

Elsewhere in Indonesia, newer methods such as Mars’s “reef stars” have shown faster recovery. These structures are more effective at stabilising rubble, but they still depend heavily on regular maintenance and monitoring.

When restoration falls short of expectations

Blast fishing is not just a relic of the past. Despite being banned for decades, it still takes place illegally in parts of Indonesia.

Moreover, the legacy of past blasting is immense — vast stretches of reef reduced to rubble, showing no sign of natural recovery.

Our research underscores three key lessons:

  • Not all rubble is the same. Storm-generated rubble is usually larger and more stable, allowing recovery to occur, whereas blast-generated rubble remains persistently unstable.

  • Size matters: longer coral fragments are more likely to stay in place, bind together, and support young corals — whereas blasts mostly produce small pieces that shift too easily.

  • Restoration requires care: structures alone won’t save a reef — interventions must be adapted to local conditions and sustained with ongoing maintenance.

Supporting reef recovery

We found that rubble from blast fishing remains unstable even after decades, with small fragments constantly shifting and preventing young corals from settling and growing. In contrast, larger pieces were more likely to stay in place, bind together, and support new coral recruits.

Our findings suggest that blast-fished reefs are unlikely to recover naturally without human intervention. Restoration must prioritise stabilising the rubble bed and employing structures suited to the site’s specific rubble characteristics. Success depends not only on installing these structures but also on maintaining them over time.

Reef managers should also identify and assess the origin of rubble, characterise the fields and fragments, and select suitable intervention methods before taking action, as we did in our study.

Coral reefs require long-term care to survive, thrive, and keep providing food, coastal protection, and tourism opportunities for millions of people. Successful restoration depends not only on the interventions themselves but also on sustained monitoring and responsible stewardship of the broader environment.

Restoration and responsible stewardship can safeguard the ecological and social benefits of coral reefs. Ultimately, giving degraded reefs a second chance is vital both for the communities that depend on them and for the biodiversity that makes them extraordinary.

Around the world, migrants are being deported at alarming rates – how did this become normalised?

Source: The Conversation – Global Perspectives – By Andonea Jon Dickson, Postdoctoral Research Fellow, University of Edinburgh

Under President Donald Trump, the United States is expanding its efforts to detain and deport non-citizens at an alarming rate. In recent months, the Trump administration made deals with a number of third states to receive deported non-citizens.

In Australia, the Labor government has similarly established new powers to deport non-citizens to third states. The government signed a secretive deal with Nauru in September, guaranteeing the small Micronesian island A$2.5 billion over the next three decades to accommodate the first cohort of deportees.

In both countries, migrants can now be banished to states to which they have no prior connection.

Last year in the United Kingdom, Prime Minister Keir Starmer’s Labour party promised that the previous Conservative government’s plan to deport people to Rwanda was “dead and buried”. Yet, Labour removed close to 35,000 people in 2024, an increase of 25% over the previous year.

Starmer has also proposed establishing “return hubs” in third countries for people with rejected asylum claims.

Meanwhile, the far-right Reform Party has put forward a “mass deportation” plan involving the use of military bases to detain and deport hundreds of thousands of people, if it wins power in the next general election.

Similar policies may soon come to Europe, too. In May, the European Commission published a proposal that would allow EU member states to deport people seeking asylum to third countries where they have no previous connection.

The deportation of populations deemed problematic is not a new practice. For centuries, states have used forms of deportation to forcibly remove people, as Australia’s own history as a British penal colony illustrates.

Today, deportations are a staple of migration governance around the world. However, the recent expansion of detention and deportations reflects an accelerated criminalisation and punishment of non-citizens, tied to a rising authoritarianism across purportedly liberal Western countries.

Criminalising movement

The expansion and outsourcing of deportation is underpinned by long histories of criminalising migration.

Over the past three decades, legal obstacles and securitised borders have increasingly forced those fleeing war, persecution and insecurity to rely on unauthorised routes to seek refuge.

Governments have simultaneously reframed the act of seeking asylum from a human right to a criminal act, brandishing those on the move as “illegal” as a way of justifying onshore and offshore immigration detention.

Racialised people living in the community have also been subject to increased policing, regardless of their migration status.

In the US, UK and Australia, this criminalising language, once the preserve of the right-wing press, is now echoed by politicians across the political spectrum and enshrined in legislation. This has accelerated what migration expert Alison Mountz has termed “the death of asylum”, and normalising deportations.

In Australia, for example, the government lowered the threshold for visa cancellations in 2014, resulting in people with minor offences being detained and scheduled for deportation. Those who could not be returned to their home countries continued to languish in detention until a 2023 high court ruling mandated their release.

Despite having served their sentences, in addition to protracted periods in immigration detention, a media frenzy framed these people as a major threat to the community. The Labor government then legislated to deport them, in addition to thousands of others on precarious visas, to a third country.

Deportations have also been a central facet of US immigration enforcement for many years.

Former President Barack Obama was branded “Deporter in Chief” for achieving a record three million deportations while in office.

While Obama focused on “felons not families”, Trump has equated migration itself with crime and insecurity. His administration has cast a much wider net, rounding up those with and without criminal convictions, including citizens.

Detentions and deportations have also been used to suppress political dissent on issues, such as the genocide in Gaza.

To expedite his pledge to deport one million people in his first year, the Trump administration hastily set up detention centres in former prisons and military bases, including at Guantánamo Bay.

Reports suggest the government has also approached 58 third countries to accept deported non-nationals. Countries that have agreed, or already received people, are shown in the map below.

In many cases, people are then re-detained on arrival in hotels, prisons and camps, with some subject to further deportation.

Rising authoritarianism

These recent developments reveal an explicit authoritarianism in which deportations are achieved through the elimination of procedural fairness. Reducing notice periods, the ability to appeal decisions, and access to legal counsel allows for rushed and opaque procedures.

In June, eight people were deported from the US to South Sudan without the chance to contest their removal. After a failed court intervention, the three liberal US Supreme Court justices stated:

The government has made clear in word and deed that it feels itself unconstrained by law, free to deport anyone, anywhere without notice or an opportunity to be heard.

In the UK, the Labour party expanded the “Deport Now Appeal Later” scheme in August, extending the countries to which people can be deported without appeal rights from eight to 23.

And this month in Australia, the Migration Act was amended to expunge the rules of natural justice for people scheduled for deportation.

Across all three countries, the rapid expansion of detention and deportation practices terrorise those targeted, leaving whole communities living in fear. Australian human rights lawyer Alison Battisson described deportation as “a creeping death to the individuals and their families”.

These policies have also legitimised and emboldened far-right, neo-Nazi groups, who have taken to the streets in both the UK and Australia in recent weeks calling for an end to migration. In both countries, the effects of decades of neoliberal policies, such as a lack of affordable housing, jobs, and health care, are redefined as a problem of migration.

How communities are responding

Communities are now organising and making the case for a different sort of politics.

In Los Angeles, for example, grassroots organisations mobilised earlier this year to counter escalating raids by Immigration and Customs Enforcement (ICE) agents. Networks also began providing information and support to those targeted by ICE arrests. In July, Detention Watch Network relaunched the Communities Not Cages coalition of grassroots campaigns against detention.

In the UK, far-right rallies at asylum hotels have been met by counter demonstrations, with people insisting on a politics of welcome and unity.

But the challenge remains how to turn local and national opposition into a coalition capable of confronting this rise in authoritarian politics of exclusion and expulsion.

Taylor Swift has branded herself a showgirl. These hardworking women have a long and bejewelled history

The iconic feathered showgirl was born amid the chaos of the first world war, when the wealthy, global French superstar Gaby Deslys entertained Parisians and Allied soldiers in a 1917 show called Laissez-les tombe! (Let Them Fall), a dazzling spectacle of ostrich feathers, rhinestones and beauty.

Although showgirls first appeared in late-19th century music halls, the red, white and blue feathered costumes in Deslys’ revue offered Paris something new and triumphal. The massed plumes, wild dancing and bodily displays celebrated French aesthetics and extravagance and communicated that France and her allies would not bow to Germany.

Prior to 1914 Deslys’s expensive jewellery, haute couture and expansive feathered hats – along with her affairs with powerful men such as department store magnate Harry Selfridge and King Manuel II of Portugal – created countless headlines.

But she was also outspoken about a woman’s right to support herself financially and worked tirelessly during the war raising funds for the Allies. Deslys was so passionate about aiding the devastated Parisian nightlife that she paid for all the costumes in Laissez-les tombe! herself.

Deslys’s cultural impact has inextricably linked feathers, high fashion, celebrity and showgirls ever since.

From France to Broadway

Feathered showgirl revues were so popular that they quickly went global. In 1920s New York, impresarios such as Florenz Ziegfeld staged luxurious Broadway productions that glorified the American showgirl.

But he made exceptions to American women. One of Ziegfeld’s most famous showgirls, Dolores, was born into poverty in London’s East End as Kathleen Mary Rose. She rose to become a supermodel who walked for the couturier Lady Duff-Gordon, known professionally as Lucile.

Ziegfeld considered Dolores one of the world’s most beautiful women. Tall, slender and graceful, she drove audiences wild when she glided across Ziegfeld’s stage and posed in opulent costumes.

On becoming a showgirl, Dolores used her modelling ability to make her fortune, earning today’s equivalent of US$10,000 a week by 1923.

Other performers harnessed the feathered showgirl aesthetic, including the celebrated twins Jenny and Rosie Dolly, who came from humble origins and used their beauty, talent and hard work to dominate American and European stages in the 1910s and 1920s.

Ziegfeld paid the Dollys the equivalent of US$64,000 weekly in 1915. Like Deslys, they became notorious for their consumption of fashion and affairs with famous men.

However, stage revues became unpopular around 1930 due to their vast expense and the rise of cinema – so the showgirl travelled to Hollywood.

There, she was celebrated in biopics such as The Great Ziegfeld (1936) with its glittering, feathered costumes by the designer Adrian.

In the second world war, showgirls boosted troop morale, like Deslys did in 1917.

Hollywood made feel-good films including the biopic The Dolly Sisters (1945), which reimagined the brunette twins as all-American blondes by casting 1940s pinup stars Betty Grable and June Haver.

From Hollywood to Vegas

From there, the American showgirl arrived in Las Vegas, performing in every hotel and casino on the strip during the 1950s and 1960s.

Like the showgirls of yore, these performers’ allure was their grace, beauty, and extravagant, expensive costumes, produced by the world’s leading designers.

Showgirls remained a fixture of Las Vegas entertainment throughout the 1970s and 1980s. Choreographers including Donn Arden and Madame Bluebell (who also worked in the Parisian revues) created hallmark, visual spectacles featuring costumes by Bob Mackie.

Jubilee!, which opened at the old MGM Grand casino in 1981, was one such revue. In addition to the vast volume of plumes, it was claimed the show had caused a global shortage of Swarovski crystals because the costumes had used them all.

In 1986 the old MGM Grand became Bally’s Casino, but Jubilee! stayed. The costumes, some of which cost more than US$7,000 each (roughly US$25,000 today), were used six nights a year for 35 years and maintained by 18 wardrobe staffers.

Jubilee! closed in 2016, but its costumes live on as valuable cultural artefacts that celebrities borrow to reinterpret the American showgirl for 21st-century audiences.

This includes demonstrating that showgirls are independent, hardworking and talented women.

From Vegas to Taylor Swift

Burlesque performer Dita Von Teese draws on the American showgirls’ legacy by wearing costumes from Jubilee! in her Las Vegas cabaret, and called the 1945 Dolly Sisters film one of her inspirations.

Pamela Anderson wore Jubilee! costumes in The Last Showgirl (2024), a film that highlights the sacrifices female performers often have to make to pursue their dreams.

Taylor Swift is the latest superstar to harness showgirl iconography.
Photographs from her new album show Swift wearing the Jubilee! “Diamond” and “Disco” costumes by Mackie.

Another photograph shows Swift in a cloud of ostrich plumes and rhinestones wearing a dark, bobbed wig: a direct reference to 1920s American showgirls and performers such as the Dolly Sisters.

Swift’s stage costumes are by the world’s leading fashion designers, while her songs often reference historical celebrities to critique how the entertainment and media industry treat female performers.

Choosing Mackie’s Jubilee! costumes allows Swift to become the American showgirl (Taylor’s Version), by tapping into a century of glamour and signalling that she too has worked hard and made sacrifices to reach the top.

The Michigan church shooting sits within a long history of hatred against Mormons in America

Source: The Conversation – Global Perspectives – By David Smith, Associate Professor in American Politics and Foreign Policy, US Studies Centre, University of Sydney

On Sunday, a gunman launched a horrifying attack on people at a Church of Jesus Christ of Latter-day Saints in Grand Blanc, Michigan.

Thomas Jacob Sanford allegedly rammed his pickup truck, adorned with American flags, into the doors of the chapel as a service was taking place. Authorities stated he shot at worshippers with an assault weapon, then set fire to the building. Four people died, and police killed Sanford at the scene shortly afterwards.

Media reports and government spokespeople suggest Sanford was motivated by a pronounced hatred of followers of the Church of Jesus Christ of Latter-day Saints (LDS), widely known as Mormons.

According to a childhood friend, Peter Tersigni, Sanford became fixated with the church when he started dating one of its members while living in Utah:

He started dating this girl and then investigated and learned about Mormons because she was a Mormon. And I know that also, he got into meth really hardcore. It messed his life up and it messed his head up. And it just happened to be at the time he was around Mormons.

The language Sanford is reported to have used to describe Mormons – calling them “the antichrist” and saying “they are going to take over the world” – taps into a conspiracist suspicion of Mormons that has existed in America since the LDS church was founded in 1830, and which is still widespread in some subcultures today.

Anti-Mormonism in American history

Joseph Smith, the founder of Mormonism, had enemies from the beginning. New Christian sects were proliferating in America, but Smith went further than most. He declared himself a “prophet” and claimed to have a new religious scripture that was equal to the Bible.

Many denounced Smith as a fraud, and his neighbours feared the political power he wielded over his growing community of followers. After the Mormons were forced out of Missouri by a state Extermination Order and a subsequent massacre, Smith was assassinated by an anti-Mormon militia in Illinois in 1844.

The Mormons fled to Utah in 1847 under the leadership of Brigham Young. There they endured decades of federal government pressure to abandon the practice of polygamy and submit to the authority of the United States, which sometimes brought in armed forces.

This may seem like remote history, but to this day many evangelical Christians fear the fast-growing but “false religion” of Mormonism will lure people away from true Christianity. There is a cottage industry of YouTubers, some of them ex-Mormons, dedicated to disproving the teachings of Joseph Smith.

Nor has the violent past been forgotten. Earlier this year Netflix released a series depicting the Mountain Meadows Massacre, perpetrated by a Mormon militia in 1857.

Jon Krakauer’s 2003 bestselling book, Under the Banner of Heaven, also made into a streaming series, explored 1980s murders in a Mormon splinter sect. The book emphasised the prevalence of violence in early LDS history.

Anti-Mormonism today

Anti-Mormon violence is relatively rare in America today, but aversion to Mormons is not.

A 2022 YouGov poll of Americans found 39% of respondents held unfavourable views of Mormons, compared to just 17% with favourable views. This net negative approval was comparable to American attitudes towards Muslims, and more negative than American attitudes towards atheists.

I argued in a 2014 study that Mormons face hostility from both sides of America’s culture wars. Many conservative Christians believe Mormons are not real Christians. At the same time, many liberal and secular-minded people associate Mormons with the Christian-right.

In 2012, the high-profile Mormon Mitt Romney became the Republican candidate for the presidential election. The number of liberal and non-religious people who said they would not vote for a Mormon for president increased significantly between 2007 and 2012, despite the fact Democratic Senate Majority Leader Harry Reid was also a Mormon.

The LDS church was also prominent in campaigns against same-sex marriage in western states in the late 2000s. This led to protests and some acts of vandalism at LDS houses of worship, prompting expressions of solidarity by other conservative religious groups.

The bipartisan nature of anti-Mormonism arguably makes it one of the more socially acceptable biases in the US. But there is a world of difference between not wanting a Mormon president, or enjoying such mockery as the Book of Mormon musical, and physically attacking Mormons.

From prejudice to violence

Between 2015 and 2024, the FBI counted 160 hate crimes reported against LDS victims. These included 63 acts of vandalism and property destruction and 29 assaults. The states with the most incidents were Utah (25), California (23), Washington (14), Tennessee (12), Georgia (10) and Nevada (10).

A 2019 report in the LDS-owned Deseret News expressed concern over rising anti-Mormon hate crimes. But it pointed out this was part of a larger trend of rising hate crime in the US, and that anti-LDS incidents were dwarfed by hate crimes targeting Jews and Muslims during the same period.

Immediately after the Grand Blanc killings, President Donald Trump called the incident “yet another targeted attack on Christians in the United States of America”.

This fits his culture-war framing of Christians being under constant attack. But it glosses over the specific animus Mormons face in American society, often from other Christians and conservatives (the alleged Grand Blanc shooter wore a Trump 2020 shirt in a social media post).

Since 2000, there have been nearly 500 homicides in American places of worship, three quarters of them by firearm. This is a bigger problem than the violence facing any one religious group.

‘Only if we help shall all be saved’: Jane Goodall showed we can all be part of the solution

Source: The Conversation – Global Perspectives – By Euan Ritchie, Professor in Wildlife Ecology and Conservation, School of Life & Environmental Sciences, Deakin University

Penelope Breese/Getty

With the passing of Dr Jane Goodall, the world has lost a conservation giant. But her extraordinary achievements leave a profound legacy.

Goodall was a world-leading expert in animal behaviour and a globally recognised environmental and conservation advocate. She achieved all this at a time when women were commonly sidelined or ignored in science.

Her work with chimpanzees showed it was wrong to assume only humans used tools. She showed us the animals expressed emotions such as love and grief and have individual personalities.

Goodall showed us scientists can express their emotions and values and that we can be respected researchers as well as passionate advocates and science communicators. After learning about how chimpanzees were being used in medical research, she spoke out: “I went to the conference as a scientist, and I left as an activist.”

As childhood rights activist Marian Wright Edelman has eloquently put it, “You can’t be what you can’t see”.

Goodall showed what it was possible to be.

Forging her own path

Goodall took a nontraditional path into science. The brave step of going into the field at the age of 26 to make observations was supported by her mother.

Despite making world-first discoveries such as tool use by non-humans, people didn’t take her seriously because she hadn’t yet gone to university. Nowadays, people who contribute wildlife observations are celebrated under the banner of citizen science.

Goodall was a beacon at a time when science was largely dominated by men – especially remote fieldwork. But she changed that narrative. She convinced famous paleoanthropologist Louis Leakey to give her a chance. He first employed her as a secretary. But it wasn’t long until he asked her to go to Tanzania’s remote Gombe Stream National Park. In 1960, she arrived.

This was not easy. It took real courage to work in a remote area with limited support alongside chimpanzees, a species thought to be peaceful but now known to be far stronger than humans and capable of killing animals and humans.

Goodall is believed to be the only person accepted into chimpanzee society. Through calm but determined persistence she won their trust. These qualities served Goodall well – not just with chimps, but throughout her entire career advocating for conservation and societal change.

At Gombe, she showed for the first time that animals could fashion and use tools, had individual personalities, expressed emotions and had a higher intelligence and understanding than they were credited with.

Jane Goodall worked with chimpanzees for decades. This 2015 video shows her releasing Wounda, an injured chimpanzee helped back to health in the Republic of Congo.

Goodall was always an animal person and her love of chimps was in part inspired by her toy Jubilee, gifted by her father. She had close bonds with her pets and extended these bonds to wildlife. Goodall gave her study subjects names such as “David Greybeard”, the first chimp to accept her at Gombe.

Some argue we shouldn’t place a human persona on animals by naming them. But Goodall showed it was not only acceptable to see animals as individuals with different behaviours, but it greatly aids connection with and care for wildlife.

Goodall became an international voice for wildlife. She used her profile to encourage a focus on animal welfare in conservation, caring for both individuals and species.

A pioneer for women in science

With Goodall’s passing, the world has lost one of the three great “nonagenarian environmental luminaries”, to use co-author Vanessa Pirotta’s phrase. The other two are the naturalist documentary maker, Sir David Attenborough, 99, and famed marine biologist Dr Sylvia Earle, who is 90.

Goodall showed us women can be pioneering scientists and renowned communicators as well as mothers.

She shared her work in ways accessible to all generations, from National Geographic documentaries to hip podcasts.

Her visibility encouraged girls and women around the world to be bold and follow our own paths.

Goodall’s story directly inspired several authors of this article.

Co-author Marissa Parrott was privileged to have spoken to Goodall several times during her visits to Melbourne Zoo and on her world tours. Goodall’s story was a direct inspiration for Parrott’s own remote and international fieldwork, supported by her mother just as Goodall’s mother had supported her. They both survived malaria, which also kills chimpanzees and gorillas. Goodall long championed a One Health approach, recognising the health of communities, wildlife and the environment are all interconnected.

Co-author Zara Bending worked and toured alongside Goodall. The experience demonstrated how conservationists could be powerful advocates through storytelling, and how our actions reveal who we are. As Goodall once said:

every single one of us matters, every single one of us has a role to play, and every single one of us makes a difference every single day.

From the forest floor to global icon

Goodall knew conservation is as much about people as it is about wildlife and wild places.

Seventeen years after beginning her groundbreaking research in Gombe, Goodall established the Jane Goodall Institute with the mission of protecting wildlife and habitat by engaging local communities.

Her institute’s global network now spans five continents and continues her legacy of community-centred conservation. Researchers have now been studying the chimps at Gombe for 65 years.

Goodall moved from fieldwork to being a global conservation icon who regularly travelled more than 300 days a year. She observed many young people across cultures and creeds who had lost hope for their future amid environmental and climate destruction. In response, she founded a second organisation, Roots & Shoots, in 1991. Her goal was:

to foster respect and compassion for all living things, to promote understanding of all cultures and beliefs, and to inspire each individual to take action to make the world a better place for people, other animals, and the environment.

Last year, Roots & Shoots groups were active in 75 countries. Their work is a testament to Goodall’s mantra: find hope in action.

Protecting nature close to home

One of Goodall’s most remarkable attributes was her drive to give people the power to take action where they were. No matter where people lived or what they did, she helped them realise they could be part of the solution.

In a busy, urbanised world, it’s easier than ever to feel disconnected from nature. Rather than presenting nature as a distant concept, Goodall made it something for everyone to experience, care for and cherish.

She showed we didn’t have to leave our normal lives behind to protect nature – we could make just as much difference in our own communities.

One of her most famous quotes rings just as true today as when she first said it:

only if we understand, can we care. Only if we care, will we help. Only if we help shall all be saved.

Let’s honour her world-changing legacy by committing to understand, care and help save all species with whom we share this world. For Jane Goodall.

Por qué la interceptación de la flotilla de ayuda a Gaza es una clara violación del derecho internacional

Source: The Conversation – (in Spanish) – By Donald Rothwell, Professor of International Law, Australian National University

Las Fuerzas de Defensa de Israel han interceptado una flotilla de buques humanitarios que intentaban llevar ayuda a Gaza, tomando el control de varios barcos y deteniendo a numerosos activistas, entre ellos Greta Thunberg.

Las interceptaciones tuvieron lugar en el mar Mediterráneo, entre 70 y 80 millas náuticas de la costa de Gaza. Se trata de aguas internacionales en las que existe la libertad de navegación para todos los buques.

Israel ha respondido argumentando que tiene un bloqueo marítimo que prohíbe la entrada a Gaza de buques extranjeros. También ha sugerido que la flotilla contaba con el apoyo de Hamás, una afirmación que los organizadores han desmentido tajantemente.

Flotillas de ayuda humanitaria a Gaza

La Flotilla Global Sumud estaba compuesta por más de 40 barcos que transportaban ayuda humanitaria (alimentos, suministros médicos y otros artículos esenciales), junto con varios cientos de parlamentarios, abogados y activistas de docenas de países.

La flotilla partió de España a finales de agosto y ha estado navegando hacia el este, con escalas en Túnez, Italia y Grecia. Durante el trayecto, los gobiernos italiano, español y griego desplegaron escoltas navales para garantizar su paso seguro.

Los pasajeros de los barcos denunciaron que habían sido acosados por drones en múltiples puntos del viaje.

Esta campaña es la última versión de un movimiento que existe desde hace más de 15 años para desafiar el bloqueo prolongado de Israel sobre la Franja de Gaza.

A principios de este año, un barco llamado Conscience que transportaba activistas y ayuda humanitaria con destino a Gaza fue alcanzado por explosiones frente a la costa de Malta.

Israel interceptó entonces el Madleen, con Thunberg y otros activistas a bordo, en junio, y el Handala en julio.

Y en 2010, una flotilla intentó llegar a Gaza con ayuda humanitaria y cientos de activistas. Comandos israelíes abordaron el Mavi Marmara, de bandera turca, lo que provocó un enfrentamiento violento que causó la muerte de diez activistas. Las muertes provocaron una condena generalizada y tensaron las relaciones entre Israel y Turquía durante años.

La legalidad del bloqueo naval de Gaza

El derecho internacional relativo a las acciones de los barcos de la flotilla y la capacidad de intervención de Israel es complejo.

Israel ha impuesto bloqueos a Gaza de diversas formas durante casi 20 años.

La base jurídica de los bloqueos y su compatibilidad con el derecho internacional, en particular el derecho del mar, ha sido objeto de controversia, lo que se puso de manifiesto durante una investigación de la ONU que siguió al incidente del Mavi Marmara.

Actualmente se considera a Israel una potencia ocupante en Gaza en virtud del derecho internacional.

Las funciones de las potencias ocupantes se codificaron en el Cuarto Convenio de Ginebra de 1949 y se basaron en las obligaciones legales que las potencias aliadas asumieron en Alemania y Japón al final de la Segunda Guerra Mundial. El Convenio de Ginebra establece un marco jurídico claro para las potencias ocupantes.

En las últimas décadas, Israel ha sido tanto una potencia ocupante de jure (reconocida por la ley) como de facto en Palestina.

En 2024, la Corte Internacional de Justicia dictaminó que la ocupación de los territorios palestinos era ilegal según el derecho internacional.

Como potencia ocupante, Israel controla todo el acceso a Gaza, ya sea por tierra, aire o mar. Los camiones de ayuda solo pueden entrar en este territorio palestino bajo estrictos controles. Los lanzamientos de ayuda de las fuerzas aéreas extranjeras que se han producido en los últimos meses también solo se han permitido bajo el estricto control de Israel.

Desde que comenzó la guerra, ha llegado muy poca ayuda por mar, ya que Israel ha restringido severamente el acceso marítimo. En 2024, Estados Unidos construyó un muelle flotante frente a la costa para entregar ayuda, pero pronto se abandonó debido a problemas meteorológicos, de seguridad y técnicos.

Sin embargo, esto indicaba claramente que Israel estaba dispuesto a permitir el flujo de ayuda marítima de su aliado más cercano, Estados Unidos. Esta excepción al bloqueo no se aplicó a otros actores humanitarios.

Interceptación de barcos en aguas internacionales

Aunque la entrega de ayuda por mar es legalmente problemática en este momento, la capacidad de Israel para interrumpir las flotillas tiene sus límites. La libertad de navegación es fundamental para el derecho del mar. Como tal, la flotilla tiene derecho a navegar sin obstáculos por el mar Mediterráneo.

Por lo tanto, cualquier acoso o detención de la flotilla en aguas internacionales constituye una clara violación del derecho internacional.

Israel puede, sin duda, ejercer control sobre las 12 millas náuticas de mar territorial frente a las costas de Gaza. El cierre del mar territorial a los buques extranjeros estaría justificado por el derecho internacional como medida de seguridad, así como para garantizar la seguridad de los buques neutrales debido a la guerra en curso.

Los organizadores de la flotilla afirmaron que sus barcos fueron interceptados entre 70 y 80 millas náuticas de la costa, mucho más allá del mar territorial de Gaza.

Sin duda, esto se hizo por razones operativas. Cuanto más se acercaba la flotilla a la costa de Gaza, más difícil sería para las Fuerzas de Defensa de Israel interceptar con éxito cada barco, lo que aumentaba la posibilidad de que al menos uno de ellos llegara a tierra.

Decenas de activistas a bordo de los barcos han sido detenidos, según se ha informado y serán puestos bajo custodia en el puerto israelí de Ashdod. Es probable que luego sean deportados rápidamente.

Los activistas también gozan de protección en virtud del derecho internacional de los derechos humanos, incluido el acceso a diplomáticos extranjeros que ejercen la protección consular de sus ciudadanos.
