« Comment ne pas être tué par la bombe atomique » En 1950, les curieux conseils de « Paris Match »

Il y a 80 ans, le 6 août 1945, se déroulait une tragédie nommée Hiroshima. Les mots de la bombe se sont alors imposés dans l’espace médiatique : « E = mc2 », « Little Boy et Fat Man », « radiations », « bikini », « gerboise », « globocide »…

Dans le Souffle d’Hiroshima, publié en 2024 aux éditions Epistémé (librement accessible en format numérique), la chercheuse Anne Wattel (Université de Lille) revient, à travers une étude culturelle qui s’étende de 1945 à 1960, sur la construction du mythe de l’atome bienfaisant.

Ci-dessous, nous reproduisons un extrait du chapitre 3, consacré à l’histoire du mot « bikini » ainsi qu’à un étonnant article publié par Paris Match en 1950.


« Il y a eu Hiroshima […] ; il y a eu Bikini avec sa parade de cochons déguisés en officiers supérieurs, ce qui ne manquerait pas de drôlerie si l’habilleuse n’était la mort. » (André Breton, 1949

Juillet 1946 : Bikini, c’est la bombe

Lorsqu’en 1946, le Français Louis Réard commercialise son minimaliste maillot de bain deux pièces, il l’accompagne du slogan : « Le bikini, première bombe anatomique. »

On appréciera – ou pas – l’humour et le coup de com’, toujours est-il que cette « bombe », présentée pour la première fois à la piscine Molitor, le 5 juillet 1946, est passée à la postérité, que le bikini s’est répandu sur les plages et a occulté l’atoll des îles Marshall qui lui conféra son nom, atoll où, dans le cadre de l’opération Crossroads, les Américains, après avoir convaincu à grand renfort de propagande la population locale de s’exiler (pour le bien de l’humanité), multiplièrent les essais atomiques entre 1946 et 1958.

La première bombe explose le 1er juillet 1946 ; l’opération est grandement médiatisée et suscite un intérêt mondial, décelable dans France-soir qui, un mois et demi avant « l’expérience », en mai 1946, renoue avec cet art subtil de la titraille qui fit tout son succès :

« Dans 40 jours, tonnerre sur le Pacifique ! Bikini, c’est la bombe » (France-soir, 19-20 mai 1946)

Mais la bombe dévie, ne touche pas l’objectif et la flotte cobaye est quasiment intacte. C’est un grand flop mondial, une déception comme le révèlent ces titres glanés dans la presse française :

  • « Deux navires coulés sur soixante-treize. “C’est tout ?” » (Ce soir, 2 juillet 1946) ;

  • « Bikini ? Ce ne fut pas le knockout attendu » (Paris-presse, 2 juillet 1946) ;

  • « À Bikini, la flotte cobaye a résisté » (France-soir, 2 juillet 1946).

C’est un « demi-ratage », un possible « truquage » pour l’Aurore (2 juillet 1946) ; et le journal Combat se demande si l’expérience de Bikini n’a pas été volontairement restreinte (Combat, 2 juillet 1946).

Les essais vont se poursuivre, mais le battage médiatique va s’apaiser. Le 26 juillet, Raymond Aron, dans Combat, évoque, effaré, la déception générale occasionnée par la première bombe et se désespère alors qu’on récidive :

« Les hommes seuls, maîtres de leur vie et de leur mort, la conquête de la nature, consacrée par la possession d’un pouvoir que les sages, dans leurs rêves, réservaient aux dieux : rien ni personne ne parviendra à voiler la grandeur tragique de ce moment historique. »

Et il conclut :

« […] Aujourd’hui, rien ne protège l’humanité d’elle-même et de sa toute-puissance mortelle. »

Premier-Avril 1950 : « Comment ne pas être tué par une bombe atomique »

L’hebdomadaire français Paris Match, qui a « le plus gros tirage dans les années 1950 avec près de 2 millions d’exemplaires chaque semaine », dont « l ‘impact est considérable » et qui « contribue à structurer les représentations », propose dans son numéro du 1er avril 1950 une couverture consacrée, comme c’est fréquemment le cas, à l’aristocratie (ici la famille royale de Belgique) mais, dans un unique encadré, bien visible en haut de page, le titre, « Comment ne pas être tué par une bombe atomique », se présente comme un véritable produit d’appel d’autant plus retentissant qu’on sait officiellement, depuis septembre 1949, que l’URSS possède la bombe atomique.

Paris Match, 54, 1er avril 1950, première de couverture et titres des pages 11 et 12.

L’article, qui nous intéresse et qui se déploie sur deux pleines pages, est écrit par Richard Gerstell qu’un encadré présente comme « un officier de la marine américaine », « un savant », « docteur en philosophie », « conseiller à la défense radiologique à l’Office de la défense civile des États-Unis ». L’auteur est chargé par le ministère de la défense d’étudier les effets de la radioactivité des essais atomiques de Bikini et d’élaborer des « plans pour la protection de la population civile contre une éventuelle attaque atomique ».

L’encadré inséré par la rédaction de Paris Match vise donc à garantir la crédibilité du rédacteur de l’article, un homme de terrain, un scientifique, dont on précise qu’il « a été exposé plusieurs fois aux radiations atomiques et n’en a d’ailleurs pas souffert physiquement (il n’a même pas perdu un cheveu) », qui rend compte de sa frayeur lorsque le compteur Geiger révéla que ses cheveux étaient « plus radioactifs que la limite ». Il s’agit donc, du moins est-ce vendu ainsi, du témoignage, de l’analyse d’un témoin de choix ; il s’agit d’une information de première main.

Bombe atomique et accident nucléaire : voici leurs effets biologiques respectifs


Dans les premiers paragraphes de l’article de Match, Gerstell explique avoir eu, dans les premiers temps, « la conviction que la destruction atomique menaçait inévitablement une grande partie de l’humanité ». C’est pourquoi il accueillit favorablement la parution de l’ouvrage de David Bradley, No Place to Hide (1948), qui alertait sur les dangers de la radioactivité. Mais il ne s’appuyait alors, confie-t-il, que sur une « impression » ; il manquait de recul. En possession désormais des « rapports complets des expériences de Bikini et des rapports préliminaires des nouvelles expériences atomiques d’Eniwetok », il a désormais « franchement changé d’avis ».

L’article publié dans Match vise un objectif : convaincre que la radioactivité, sur laquelle on en sait plus que sur « la poliomyélite ou le rhume », « n’est, au fond, pas plus dangereuse que la fièvre typhoïde ou d’autres maladies qui suivent d’habitude les ravages d’un bombardement ».

Fort de son « expérience “Bikini” », durant laquelle, dit-il, « aucun des 40 000 hommes » qui y participèrent « ne fut atteint par la radioactivité », Gerstell entend mettre un terme aux « légendes » sur les effets de cette dernière (elle entraînerait la stérilité, rendrait des régions « inhabitables à jamais »). « Tout cela est faux », clame-t-il ; la radioactivité est « une menace beaucoup moins grande que la majorité des gens le croient ».

Un certain nombre de précautions, de conseils à suivre pour se protéger de la radioactivité en cas d’explosion nucléaire sont livrés aux lecteurs de Paris Match : fermer portes et fenêtres, baisser les persiennes, tirer les rideaux ; ôter ses souliers, ses vêtements avant de rentrer chez soi, les laver et frotter ; prendre des douches « copieuses » pour se débarrasser des matières radioactives ; éviter les flaques d’eau, marcher contre le vent ; s’abriter dans une cave, « protection la plus adéquate contre les radiations »…

On laisse le lecteur apprécier l’efficacité de ces mesures…

Pour se protéger de la bombe elle-même dont « la plupart des dégâts sont causés par les effets indirects de l’explosion », se coucher à plat ventre, yeux fermés ; pour éviter les brûlures, trouver une barrière efficace (mur, égout, fossé) ; porter des « vêtements en coton clair », des pantalons longs, des blouses larges, « un chapeau aux bords rabattus »…

Ainsi, ce témoin, ce « savant », qui étudia l’impact de la radioactivité, rassure-t-il le lectorat français de Match : on peut se protéger de la bombe atomique, des radiations ; il suffit d’être précautionneux.

Foin des légendes ! Ce regard éclairé, scientifiquement éclairé, s’appuie sur l’expérience, sur Bikini, sur Hiroshima et Nagasaki pour minorer (et c’est peu dire) le danger des radiations, car, c’est bien connu, « les nuages radioactifs à caractère persistant sont vite dissipés dans le ciel » (cela n’est pas sans nous rappeler l’incroyable mythe du nuage qui, à la suite de la catastrophe de Tchernobyl, le 26 avril 1986, se serait arrêté aux frontières de la France) ; « la poussière radio-active persistante qui se dépose sur la peau ne paraît pas dangereuse » ; « au voisinage immédiat du point d’explosion, une pleine sécurité peut être assurée par 30 centimètres d’acier, 1 mètre de béton ou 1 m 60 de terre. À un kilomètre et demi, la protection nécessaire tombe à moins d’un centimètre d’acier et quelques centimètres de béton ».

En avril 1950, l’Américain Richard Gerstell, dont les propos sont relayés en France par l’hebdomadaire Paris Match, niait encore l’impact de la radioactivité.

Friday essay: Trump and Kennedy are destroying global science. Even Einstein questioned facts – but there’s a method to it

Source: The Conversation – Global Perspectives – By Elizabeth Finkel, Vice-Chancellor’s Fellow, La Trobe University

Eight months into Donald Trump’s second presidency of the United States, truth and science are again under attack – with global consequences. USAID, which tackled HIV, TB, malaria and child malnutrition is gone. Funding has been withdrawn from GAVI, a public–private global alliance that helps buy vaccines for the world’s poorest children. Malnourished children are already dying.

Besides these brutal consequences, the scientific machine that delivered America’s scientific and technological dominance is being ruthlessly dismantled. Any research project that mentions diversity, equity and inclusion (DEI), climate change or addresses the causes of vaccine hesitancy is a prime target. But even US space science, once the pride of the nation, is facing “an extinction-level event,” according to the US Planetary Society.

Across the spectrum of science, some 4,000 research grants have been cancelled. Unbelievably, bird-flu experts were fired in the middle of an outbreak. That was topped last May by cancelling a US$600M grant to the company Moderna to develop an mRNA vaccine against bird flu.

And this Tuesday, US$500 million was cancelled for 22 more projects developing mRNA vaccines. Bear in mind that under Operation Warp Speed, the first Trump administration funded the development of Moderna’s mRNA vaccine against COVID. Moderna and Pfizer-BioNTech both delivered mRNA vaccines in the record time of less than a year, winning mRNA vaccine technology a Nobel Prize in 2023.

It’s not just American science that’s being dismantled.

Threats to Australian science, too

In March, the Trump administration sent a questionnaire to researchers receiving US funding in Australia, the European Union, the United Kingdom and Canada. The 36 questions included whether their project related to climate, whether it is taking “appropriate measures” to defend against “gender ideology” and whether the organisation receives funding from China.

US funding for collaborative science projects with Australia amounts to AUD$386 million. So, the threat of losing those substantial funds is dire. As the Australian Academy of Science warned last March, if US–Australian collaboration ceases, “it will directly threaten […] strategic capability in areas of national interest such as defence, health, disaster mitigation and response, AI and quantum technology”.

By June, Australian medical research institutes were “suspending projects on malaria, tuberculosis and women’s health”. It’s like “having a bomb thrown into the middle of science”, noted Professor Brendan Crabb, director of the Burnet Institute, a Melbourne-based global health research centre.

The fallout for US medical research is worse. The Trump administration’s proposed funding cut, to the National Institutes of health, the largest funder of medical research in the world, will see its budget slashed by 40% – and over 2,400 projects cancelled. They include research into cancer, Parkinson’s disease, Alzheimer’s disease, tuberculosis, HIV prevention, COVID vaccines and long-COVID.

Experts have been summarily fired and replaced by sycophants. And of course, the Department of Health and Human Services is now led by America’s most prominent anti-vaxxer, Robert F. Kennedy Junior. Elite research universities, including Harvard, Columbia, Princeton and Cornell, continue to be prime targets.

“It’s hard to overstate how serious this is […] Today, as we’re witnessing kind of the destruction of the institutions behind American science, it’s hard to believe. It’s hard to believe any administration would do this,” noted Alan Bernstein, director of global public health at Oxford University, in April.

Indeed, how could this be happening?

Erika Nolan, a MAHA (Make America Healthy Again) stalwart and YouTube influencer, provides a candid answer: “Facts no longer matter.” Nolan plies her 200,000 strong audience with idyllic scenes of herding chickens and goats while snuggling her baby in a front pack.

Like Kennedy, Nolan believes America’s big health issues relate to food dyes and seed oils. Hopefully she does not live in a part of the US where measles or whooping cough is raging, and that her chicken flock won’t come down with bird flu.

She says it was COVID, and the pressure to be vaccinated, that “fast-tracked” her. And when asked about the 14 million lives saved in the first year, as reported in peer-reviewed medical journal, the Lancet, her answer is, “Everything can be manipulated.”

What Nolan doesn’t understand is that modern science emerged precisely to deal with the way everything can be manipulated. The very word science comes from scientia, Latin for knowledge. The gist of it is captured by the motto adopted in 1663 by the Royal Society in London: “Nullius in verba.”. That’s Latin for “Take nobody’s word for it.” In other words, experimentation and observation is what counts, not the opinions of influencers.

Nolan might be surprised to find her scepticism over “facts” goes all the way back to Socrates.

Knowledge, power and science

He left no written works, but we hear his voice through the “dialogues” of his student Plato. Ever so gently, Socrates probes the beliefs of his conversation partner, methodically laying bare their logical fallacies. It has come to be known as the Socratic method.

One of the most famous dialogues employs the allegory of a cave to teach Socrates’ primary lesson: knowledge can be based on false beliefs.

The cave is home to a group of prisoners who have been chained up for their entire lives. All they have ever been allowed to see is the cave wall in front of them. Shadows dance across it, representing the reality of the external world. The prisoners have no idea that the images are created by puppets paraded past a blazing fire just behind them.

One prisoner breaks free and climbs out of the cave. Dazed by the sunlight, it takes time for his sensitive eyes to adapt. At first, he is only able to look at shadows, then reflections, then real objects. He dashes back to the cave to enlighten his fellow captives. But his eyes have not readjusted to the dark and he stumbles around.

The prisoners perceive a blinded, deranged man, raving about a parallel world. They want nothing to do with him and become aggressive. This is Plato’s second lesson: the danger of trying to enlighten those wedded to pre-existing beliefs. Poignantly, Socrates would pay with his life for trying to enlighten others.

It would take over 2,000 years to come up with satisfactory responses to some of Socrates’ questions about the nature of knowledge. They appeared in the form of the scientific revolution.

Stars of the scientific revolution

The scientific revolution was ushered in by the exacting astronomical measurements of Copernicus, Galileo and Kepler, which revealed that Earth and the other planets were in orbit around the sun, rather than the other way round.

Brilliant as these astronomers were, they were just the warm-up acts. The starring role in the scientific revolution goes to Isaac Newton, who honoured his debt to those who came before with the timeless words: “If I have seen further, it is by standing on the shoulders of giants.” Standing on the shoulders of Copernicus, Galileo and Kepler, Newton glimpsed the sun-centred universe and pondered a new question: why did the planets orbit the sun?

The French philosopher Descartes had suggested an answer in 1633. He deemed that something like a giant tornado of dust particles raged around the sun, dragging the planets along with them.

Newton was seven years old when Descartes died. By the time Newton was 26, he was the Lucasian Professor of Mathematics at Cambridge, no doubt for the stunning discoveries he made during the plague years, which he spent in isolation at his mother’s farm in Lincolnshire. “Truth is the offspring of silence and unbroken meditation,” he noted.

His unbroken meditation gave birth to calculus, optics (in the pursuit of which he stuck a blunt needle into his eye), his laws of motion and the beginnings of his theory of gravity. Seeing an apple fall from a tree was famously his Eureka moment. The force that made the apple fall to the earth, he mused, was likely the same as the one binding the planets to the elliptical solar orbits described by Kepler.

Today, most people have no problem with the idea of gravity as a force that pulls the apple to the ground or the earth to the sun. It was a different story in Newton’s time. Descartes’ tornado seemed the more rational explanation.

How could the sun reach out across the vastness of space to pull on our planet? This was “barbaric physics”, opined German mathematician and philosopher Gottfried Leibniz. Admittedly, Leibniz was peeved with Newton; they had rival claims as the first to develop calculus. But Leibniz was far from being the only one to label Newton’s theory unscientific.

What vindicated Newton’s theory was that it made testable, precise predictions. It specified that the gravitational force between two objects increases with their masses and decreases as they grow further apart.

Newton’s maths proved correct. It accurately predicted how long it would take for the moon to orbit the earth and the coming of Halley’s comet. His formula also predicted that the warped orbit of Uranus was due to the gravitational pull of a ghost planet. A century and a half later, Neptune was found. For 300 years, Newton’s predictions kept hitting the mark. And for most earth-bound situations, they still do.

Newton represents a watershed in the development of science. The peculiar thing about him, and what made him the lead actor of the scientific revolution, was that his theory, unlike those of Aristotle or Descartes, was limited to what could be accounted for by mathematical predictions. He did not attempt to go beyond the data to explain what gravity is or whether it really existed: “I have not as yet been able to deduce from phenomena the reason for these properties of gravity, and I do not feign hypotheses,” he wrote.

Philosophy of science

This notion of science as being light on theory is familiar to me. As a scientist (before I was a science writer, I was a molecular biologist), my contribution to theory was limited to what could be induced from my last successful experiment. In my ten years as a working scientist, I never encountered the philosophy of science. Nor did I encounter it much in my decades writing about the work of other scientists.

But in researching my book Prove It, which would see me roam widely, from theoretical physics to human evolution, and deeply, across the centuries, I knew I would have to reckon with the philosophy of science. I did not relish the task: reading philosophy can be challenging.

Moreover, I was not convinced that there was much philosophy at work in modern science. According to Michael Strevens, a philosopher of science based at New York University, when scientists themselves are placed under the microscope to dissect their philosophical impulses, nothing coherent emerges beyond a compulsion to test, test, test. As physicist Richard Feynman put it, “the philosophy of science is about as useful to science as ornithology is to birds”.

To my surprise, delight and relief, however, once I started investigating, philosophy emerged unbidden, first in the form of the Scottish enlightenment philosopher David Hume, whose ideas provided a natural kick-off point for the chapters that followed.

Like other Enlightenment philosophers, Hume valued individual reasoning over dogma and drew inspiration from the scientific revolution, particularly Newton, whom he described as “the greatest and rarest genius that ever arose for the ornament and instruction of the species”.

Newton inspired Hume, and Hume in turn inspired Albert Einstein to do what Newton could not: develop a theory of gravity.

Einstein’s ‘intellectual habits’

Einstein discovered Hume in 1902 while working as a patent clerk in Bern, Switzerland, in his early twenties. For fun, he and two colleagues formed a reading group to discuss philosophy. They paid particular attention to Hume’s 1739 A Treatise of Human Nature, in which Hume warned about the dangers of induction, the practice of extrapolating from observations to formulate general laws of the universe.

It may have been the method Newton employed, but it was an “intellectual habit” without a solid philosophical foundation, Hume argued. A well-known example concerns the colour of swans. Since Roman times, the whiteness of swans was held by European writers to be a self-evident truth. But in 1697, Dutch sea captain Willem de Vlamingh, while searching for shipwreck survivors on Australia’s west coast, sailed up a river and, lo, beheld black swans! The incident provided the name of Perth’s Swan River and a salutary philosophical lesson.

For Einstein, Hume’s ideas helped him to let go of his “intellectual habits”, a breakthrough that contributed to his theories of Special Relativity and General Relativity. Had he not read Hume, Einstein reflected, “I cannot say that the solution would have come.”

Einstein freed himself from the intellectual habit of induction by using a “deductive” process instead. It relied not on observations but on the mathematical certainty of the constant speed of light. All very well for Einstein – but the vast majority of scientists do not have the luxury of starting from mathematical certainties. While Einstein’s theory of relativity has endured unchanged for more than a century, the same cannot be said of any of the other theories explored in Prove It.

I needed Einstein to introduce me to David Hume, but Karl Popper needed no introduction. He is the most famous philosopher of science of the 20th century. If you’ve come across the idea that scientific theories can’t be proven, only disproven or “falsified”, that’s courtesy of Popper.

Karl Popper: science as search for truth

Popper has a poignant personal story that resonates strongly with my motive for writing a scientific guide for the post-truth era.

Karl Popper.
Lucinda Douglas-Menzies/Wikipedia

Born in 1902 into a cultivated, scholarly home – his mother a pianist, his father a lawyer – Popper’s first decade was lived in Vienna’s golden age. As the capital of the Austro-Hungarian Empire, Vienna was the seat of political power, but also a cauldron of European cultural and intellectual ferment.

Modernism exploded: there was the stylised eroticism of Gustav Klimt’s shimmering gold paintings and the raw sexual canvases of Egon Schiele; the absurdist literature of Franz Kafka and the meltingly poetic work of Rainer Maria Rilke; the hauntingly beautiful music of Gustav Mahler and the atonal work of Arnold Schoenberg; the philosophy of Ludwig Wittgenstein; and of course, Sigmund Freud’s revolutionary theories about the life of the unconscious mind.

“In those first fourteen years of the twentieth century, Vienna, more than anywhere else, was the fulminating, bewitching crucible where the modern world was invented,” writes William Boyd.

Popper witnessed its destruction. He was 12 when the first world war broke out and 37 when the second one came around. In between, he flirted with and rejected Marxism, tried his hand at carpentry and teaching, and managed to complete a PhD in the philosophy of psychology. With the rise of Nazism, his Jewish ancestry erased his job prospects. To build a reputation, he wrote a book, The Logic of Scientific Discovery.

Published in 1934, it introduced his theory that the way to distinguish science from non-science is falsification. His ideas struck a chord and won him an offer to teach philosophy at Canterbury University College in Christchurch, New Zealand. He emigrated with his wife in 1937, a year before Austria was annexed by Hitler. In 1946, he moved to the United Kingdom to found the department of philosophy at the London School of Economics.

Popper experienced firsthand what can happen to the most intellectually progressive of civilisations when a populist ideology takes hold. How could a philosopher protect future generations from such an assault on truth? Like the Enlightenment thinkers before him, his answer was the scientific method. “Truth is therefore the aim of science; science is the search for truth,” he wrote.

Testing Einstein

I was delighted to discover that Popper’s theory was inspired by Einstein! As a teenager, Popper heard Einstein expound on his astonishing theory of General Relativity in Vienna in 1919.

Gravity was not a force, Einstein suggested, but a consequence of the way mass causes a curvature in spacetime. A fantastical theory! But in the same breath, Einstein proposed a way to prove his theory wrong. During an eclipse, the moon blocks the sun, and the dark sky makes the stars near the sun suddenly visible. Although the stars themselves are very far away from the sun, their light rays must pass close by it to be seen by people watching the eclipse.

Einstein predicted that the starlight would curve along the spacetime warped by the sun’s huge mass. As a result, the apparent positions of the stars would be shifted by an exact amount predicted by Einstein’s equations.

Bottom line: Einstein’s theory could be falsified, and Einstein offered his critics a way to do it. As Popper put it, “Thus I arrived, by the end of 1919, at the conclusion that the scientific attitude was the critical attitude, which did not look for verifications but for crucial tests; tests which could refute the theory tested, though they could never establish it.”

Science cannot prove theories, because, as Hume pointed out, what’s true today may not be true tomorrow. Just because we observe a phenomenon once doesn’t mean we can assume it will happen again. But science can certainly disprove things.

That’s what distinguishes scientific theories from, say, Freud’s theory of the unconscious or Marx’s theory of historical materialism. Those theories do not offer falsifiable predictions. You might agree or disagree with them, but there is no way to disprove them. Science, by contrast, offers predictions that can be tested and therefore falsified. “I believe I have solved the problem of induction,” Popper declared.

Popper had his detractors. One was his former student Imre Lakatos, who embraced the importance of falsification but argued that in practice, theories are rarely overturned by contradictory data. “Scientists have thick skins,” he wrote. “They do not abandon a theory because facts contradict it. They normally either invent some rescue hypothesis to explain what they then call a mere anomaly and if they cannot explain the anomaly, they ignore it.”

The philosopher most diametrically opposed to Popper was the American, Thomas Kuhn. No doubt you’ve heard the term “paradigm shift”? That’s thanks to Kuhn and his 1962 book The Structure of Scientific Revolutions, which sold over a million copies. According to Kuhn, modern scientists, rather than attempting to falsify their theories, do the exact opposite: they design experiments to affirm them.

These disputes notwithstanding, the hunt for the origins of COVID-19 showed me Popper is alive and well in the modern science lab. “Popperian” scientists were among the first to propose that the virus came from a lab. They then tried to see if they could disprove their own theory – and largely succeeded. The weight of evidence points to the virus spilling into the human population from an animal source.

Shared reality and true science

The scientific method doesn’t just apply to science. In his book, The Constitution of Knowledge, Jonathan Rauch, a senior fellow in governance at Brookings Institute, notes that the institutions that underpin democracies – academia, law, journalism and government – need to operate based on a shared reality. To do so, they employ the scientific method the gathering and testing of facts.

The Trump administration seems to have declared war on every aspect of the scientific method. It has declared war on fact-checking, triggering a global pile-on. Meta announced in January it would scrap its fact-checking programs. And last month, Google announced it will not renew its fact-checking contract with Australian Associated Press.

The Trump administration has also taken an axe to the workings of the scientific machine. In a breathtaking example of Orwellian “double speak”, on May 23, Trump issued an executive order to restore “gold standard science”.

What this means, explains New York University bioethicist Arthur Caplan, is that “instead of independent expert reviews of research, a Trump functionary can look at any peer-reviewed work and declare it to be in violation of the President’s gold standard”. He concluded that the US “has never had a situation in which political and ideological nonscientists got the last word about what is credible science”.

The history of authoritarian regimes tells us when ideologues take over science, it does not end well. It was the Nazi takeover of German universities that saw the likes of Einstein seek refuge in the US – and turned America into a scientific superpower.

The scientific method, designed to keep human failings in check, is the best guide for navigating the present era. Here are my guiding principles:

  1. Go to the experts. See what is being published in leading journals, find a good plain-language summary and check several sources. Science and Nature both offer excellent free reporting, as does The Conversation and The New York Times.

  2. Expert opinion seeks consensus. Consensus may be tough to obtain among scientists, but it is based on a convergence of evidence from different sources.

  3. Anyone who tries to whip up an emotional response, or who has a predetermined opinion or conflict of interest, is a red flag. Scientific evidence is generally measured. It comes with margins of error and estimates of effectiveness and risk. A scientist who offers opinions outside their field of expertise is also one to whom I would give less weight.

Our health, our agriculture, our environmental safety, our ability to ameliorate and adapt to climate change, to regulate AI and to fight the next pandemic, all rely on the proper functioning of the scientific machine. We must not stand by and see it dismantled.

Are you in a mid-career to senior job? Don’t fear AI – you could have this important advantage

Source: The Conversation – Global Perspectives – By Kai Riemer, Professor of Information Technology and Organisation, University of Sydney

Have you ever sat in a meeting where someone half your age casually mentions “prompting ChatGPT” or “running this through AI”, and felt a familiar knot in your stomach? You’re not alone.

There’s a growing narrative that artificial intelligence (AI) is inherently ageist, that older workers will be disproportionately hit by job displacement and are more reluctant to adopt AI tools.

But such assumptions – especially that youth is a built-in advantage when it comes to AI – might not actually hold.

While ageism in hiring is a real concern, if you have decades of work experience, your skills, knowledge and judgement could be exactly what’s needed to harness AI’s power – without falling into its traps.

What does the research say?

The research on who benefits most from AI at work is surprisingly murky, partly because it’s still early days for systematic studies on AI and work.

Some research suggests lower-skilled workers might have more to gain than high-skilled workers on certain straightforward tasks. The picture becomes much less clear under real-world conditions, especially for complex work that relies heavily on judgement and experience.


This article is part of The Conversation’s series on jobs in the age of AI. Leading experts examine what AI means for workers at different career stages, how AI is reshaping our economy – and what you can do to prepare.


Through our Skills Horizon research project, where we’ve been talking to Australian and global senior leaders across different industries, we’re hearing a more nuanced story.

Many older workers do experience AI as deeply unsettling. As one US-based CEO of a large multinational corporation told us:

AI can be a form of existential challenge, not only to what you’re doing, but how you view yourself.

But leaders are also observing an important and unexpected distinction: experienced workers are often much better at judging the quality of AI outputs. This might become one of the most important skills, given that AI occasionally hallucinates or gets things wrong.

The CEO of a South American creative agency put it bluntly:

Senior colleagues are using multiple AIs. If they don’t have the right solution, they re-prompt, iterate, but the juniors are satisfied with the first answer, they copy, paste and think they’re finished. They don’t yet know what they are looking for, and the danger is that they will not learn what to look for if they keep working that way.

Experience as an AI advantage

Experienced workers have a crucial advantage when it comes to prompting AI: they understand context and usually know how to express it clearly.

While a junior advertising creative might ask an AI to “Write copy for a sustainability campaign”, a seasoned account director knows to specify “Write conversational social media copy for a sustainable fashion brand targeting eco-conscious millennials, emphasising our client’s zero-waste manufacturing process and keeping the tone authentic but not preachy”.

This skill mirrors what experienced professionals do when briefing junior colleagues or freelancers: providing detailed instructions, accounting for audience, objectives, and constraints. It’s a competency developed through years of managing teams and projects.

Younger workers, despite their comfort with technology, may actually be at a disadvantage here. There’s a crucial difference between using technology frequently and using it well.

Many young people may become too accustomed to AI assistance. A survey of US teens this year found 72% had used an AI companion app. Some children and teens are turning to chatbots for everyday decisions.

Without the professional experience to recognise when something doesn’t quite fit, younger workers risk accepting AI responses that feel right – effectively “vibing” their work – rather than developing the analytical skills to evaluate AI usefulness.

So what can you do?

First, everyone benefits from learning more about AI. In our time educating everyone from students to senior leaders and CEOs, we find that misunderstandings about how AI works have little to do with age.

A good place to start is reading up on what AI is and what it can do for you:

If you’re not even sure which AI platform to try, we would recommend testing the most prominent ones, OpenAI’s ChatGPT, Anthropic’s Claude, and Google’s Gemini.

The biggest barrier to AI adoption in the business world isn’t tech – it’s user confidence


If you’re an experienced worker feeling threatened by AI, lean into your strengths. Your decades of experience with delegation, context-setting, and critical evaluation are exactly what AI tools need.

Start small. Pick one regular work task and experiment with AI assistance, using your judgement to evaluate and refine outputs. Practice prompting like you’re briefing a junior colleague: be specific about context, constraints, and desired outcomes, and repeat the process as needed.

Most importantly, don’t feel threatened. In a workplace increasingly filled with AI-generated content, your ability to spot what doesn’t quite fit, and to know what questions to ask, has never been more valuable.

Move over Mercury – Chiron is in retrograde. What even is Chiron?

You might have seen an interesting phrase popping up in your social media feeds lately: “Chiron is in retrograde.” If you’re anything like me, you’ve never heard of Chiron before – and I’m a professional astronomer.

So what is Chiron, and what does it mean to be in retrograde? The short answer is that Chiron is an asteroid-slash-comet orbiting somewhere past Jupiter and Saturn. And until January 2026, it’s going to look like it’s going backwards in the sky. If you can spot it.

But there’s a bit more to the story.

What is Chiron?

Chiron’s official name is (2060) Chiron. First things first: it’s pronounced “kai-ruhn”, with a hard K sound.

It was discovered by astronomer Charles Kowal in 1977. This was long after the system of Western astrology was developed, which probably explains why people who check their daily horoscopes are also blissfully unaware of its existence.

It was initially classified as an asteroid, or a rock in space. In 1989 astronomers discovered Chiron sometimes has a tail or “coma”, which tells us that it’s actually a comet or a “dirty snowball”. Since then, Chiron has been classified as both an asteroid and a comet.

In 2023, more than 45 years after it was first discovered, astronomers confirmed Chiron has rings. This makes it the fourth non-planet in the Solar System to have rings. (The planets Jupiter, Saturn, Uranus and Neptune have rings, as do the asteroid Chariklo and the dwarf planets Haumea and Quaoar.)

Chiron orbits the Sun in an oval-shaped orbit. The closest it gets to the Sun is about 1.3 billion kilometres (about eight times the distance between Earth and the Sun) and the furthest it gets from the Sun is a whopping 2.7 billion km (about 19 times the distance between Earth and the Sun).

This puts it between the orbits of Jupiter and Uranus, cutting through the orbit of Saturn.

Centaurs in space

Chiron is a member of the Centaurs. This is a group of small Solar System bodies that orbit the Sun between Jupiter and Neptune. Their orbits are highly unstable: they change over time because of gravitational interactions with the giant planets.

In Greek mythology, centaurs were creatures with the lower body and legs of a horse and the torso and arms of a human. Chiron was the oldest centaur, the son of the Titan Kronos. He was considered the wisest centaur.

Fans of Percy Jackson and the Olympians may also recognise Chiron as the director of Camp Halfblood.

Chiron in retrograde

In astronomy, retrograde motion is when something is going backwards compared with everything else.

Apparent retrograde motion is where an object in the sky, such as a planet, appears to be going backwards when we look at it from Earth. The object hasn’t actually changed direction; it just looks like it from our perspective.

All the planets (and Chiron) orbit the Sun in the same direction. This means the planets typically look like they are moving in a west-to-east direction across the sky. But when Earth “catches” up to a planet (or a planet catches up to Earth) and overtakes it, the planet temporarily appears to move in a west-to-east direction in the sky.

This temporary illusion is apparent retrograde motion. It’s just like when you’re driving in a car and overtake a slower car, that slower car looks like it’s going backwards as you overtake it.

Chiron went into retrograde (that is, apparent retrograde motion) on July 30 2025 and will go back to normal on January 2 2026. But unless you have a telescope or do some long-exposure photography, you’d never know which way Chiron is travelling. Chiron is very faint, so you can’t see it with your eyes.

The ancient astrologers didn’t know about Chiron, but I like to think they’d appreciate a centaur in space with a ring on it.

Spy novelist Stella Rimington, the first female head of MI5, was a ‘true trailblazer’

Source: The Conversation – Global Perspectives – By Sue Turnbull, Honorary Professor of Communication and Media Studies, University of Wollongong

Dame Stella Rimington, former director general of the UK’s domestic counter-intelligence and security agency, MI5, and author of several spy thrillers, has died this week, aged 90.

A decade ago, Rimington came to Melbourne to promote her latest spy thriller, featuring her alter ego Liz Carlyle, also an MI5 agent. I was invited, as convenor of Sisters in Crime Australia, to interview her before an appreciative audience at Readings bookshop in Hawthorn. They were clearly delighted to be hearing from a real-life spy – especially one widely credited as the blueprint for Judi Dench’s version of M in the Bond movies.

Tall, elegant, impeccably dressed and sharp as a stiletto, Dame Stella was everything we wanted her to be: a woman who had made it to the top in the macho world of espionage.

Her literary legacy includes a 2001 autobiography, Open Secret, (widely seen as disappointing) and several spy thrillers, which gained a dedicated following. Her 2004 debut thriller, At Risk, was praised in the Guardian as “a cracking good thriller” with “nitty-gritty insider detail”. Together, her books provide a fascinating insight into a clandestine world more usually presented from what she herself described as a masculine point of view.

“When you think about it, all fictional spies are blokes, and spy writers when I started were chaps too,” she told the Edinburgh International Book Festival of her Liz Carlyle novels in 2015. “So I was certain that my character was going to be female. I wanted her to reflect accurately what a female does in my former service.”

Both of her female protagonists, Carlyle and CIA agent Manon Tyler (in her final two novels), reflected aspects of her own personality. Their adventures, blended with the challenges of ordinary life – relationships, workplace politics, insecurities – took readers around the world as they dealt with “fictional” threats to the nation.

An accidental spy

Sir Richard Moore, head of MI6, the foreign intelligence branch of the UK secret service, has called Rimington a “true trailblazer”. MI5 itself states it “underwent far-reaching transformation under Dame Stella’s leadership”, reports the BBC.

But she never set out to be a spy. Born in South London in 1935, she went to Edinburgh University in 1954, where she earned a master’s degree in English and literature – which shows where a good humanities degree can get you. After training as an archivist, she married John Rimington, who she accompanied to India when he took up a position at the High Commission in New Delhi.

After two years of tea parties and amateur dramatics, Rimington was asked to help out with some office work for one of the First Secretaries, who just happened to be working for MI5. As she later explained, she was subsequently “tapped on the shoulder”. Eventually, she would climb from the “typing pool to the top”.

Her elevation was never going to be easy in the hard-drinking, masculine culture of the 1970s secret service, when women were paid much less than their male counterparts. Describing herself and her female colleagues as “restive”, Rimington admitted it took something of a rebellion in the ranks before women were recognised as equals, culminating in her appointment as the first female director of MI5 in 1992.

She was also the first head of MI5 to be publicly identified, before retiring in 1996. Her family were forced to flee their London house to escape the tabloids, which published headlines like “Housewife super spy”. She later said it was the point where she “felt most unsafe”. She was, however, broadly in favour of greater public openness about the UK’s intelligence services.

Given the presumed end of the Cold War, the major threats Rimington had to deal with were largely those of domestic terrorism: threats she was required to report to then prime minister John Major. Apparently, there was often very little information to go on, at which point Major would respond “Oh well, Stella, do your best”, which she invariably did.

Booker judging and a publishing uproar

After her retirement, Rimington maintained an active public life, joining the boards of such venerable British institutions as Marks and Spencer.

In 2011, she served as chair of the judging panel for the Man Booker Prize. This created something of a stir, when the judges espoused “readability” and the ability to “zip along” as criteria they would use to assess the prize. This did not go down well – and some critics called the subsequent shortlist “was the worst in decades”.

Defending the judges’ decision at the awards ceremony, Rimington had the temerity to compare the publishing world to the KGB, thanks to its use of “black propaganda, destabilisation operations, plots and double agents”. Sounds like a great idea for a crime novel – of which she wrote a few.

Her autobiography and novels had to be submitted to MI5 for vetting and clearance. She was occasionally asked to change names and places.

Asked to write a new introduction to an anthology of stories edited by Hugh and Graham Greene, The Spy’s Bedtime Book, Rimington suggested the spy novel is “in a special class of literature in which the real and the imaginary can be mixed in any proportion, so long as they both are present”. Arguably, this is true of all literature.

The world is still dangerous

As Rimington informed the audience at the Wheeler Centre in Melbourne in 2012, the world is still a dangerous place. Then, she pointed to the continuing rise of domestic terrorism, instability in the Middle East and Putin’s ongoing aggression towards the West. How right she has proved to be – which is hardly any consolation.

“There’s so much to discover in spy stories,” she once said. “It’s a small ‘lifting of the curtains’ of a world that people know exists but don’t know much about.”

Rimington was an exceptional woman whose books document the challenging times she lived through, from an insider’s unique perspective on the front line. The line between the reality of Stella Rimington and the fiction she created may be hard to draw – which makes them fascinating reading.

Cambodia is vowing to ‘rid’ the country of scam compounds. But we’ve seen several still operating in the open

Source: The Conversation – Global Perspectives – By Ivan Franceschini, Lecturer, Chinese Studies, The University of Melbourne

Last month, the Cambodian government launched the largest crackdown to date on the online scam industry that has taken root in the country and operated largely in the open.

On July 16, a directive from Prime Minister Hun Manet acknowledged the growing threat posed by the industry and instructed provincial officials, law enforcement agencies, the courts and the national gambling commission to take action.

As police began raiding scam sites across the country, Telegram channels used by cyber criminals went into a frenzy, warning others of the seriousness of the crackdown.

Some posts claimed the police were setting up roadblocks across the country, detaining people without passports and demanding bribes for their release. Videos also circulated showing mass evacuations from compounds.

The government was soon trumpeting its success. In late July, it announced that raids had been conducted at nearly 140 locations, leading to the arrests of more than 3,000 suspects from at least 19 countries, more than half of them from China and Vietnam.

Significantly, the authorities said very few of these “suspects” had been held against their will. However, we know from our research, previously published in The Conversation, that thousands of people have been trafficked or duped into these compounds and forced to work in conditions akin to modern slavery.

The crackdown was met with praise from China and other countries. Many of these governments have been struggling with the consequences of the scam industry, whether through the trafficking of their citizens to Cambodia or scammers targeting victims in their countries.

However, despite the scale of the operation – and the government’s pledge to “get rid” of scam syndicates in Cambodia – there is widespread scepticism these efforts will be enough to dismantle the industry.

Scam Factories: the inside story of Southeast Asia’s brutal fraud compounds


Simmering border tensions

The crackdown last month coincided with a brief conflict between Thailand and Cambodia that displaced more than 300,000 people.

Analysts have pointed to long-simmering tensions over the countries’ border and rising tensions over the death of a Cambodian soldier in a skirmish in May as the reason for the hostilities.

However, Thailand has attributed the conflict to its own crackdown on Cambodian scam operations.

Earlier this year, Thailand cut power and internet service to the border scam hotspot of Poipet City.

Then, in early July, Thailand took the unprecedented step of going after a powerful Cambodian senator and tycoon known to own large properties in Poipet that Thai authorities allege are connected to online scam operations.

Thailand’s criminal court issued an arrest warrant for the senator and raided his properties in Thailand. The authorities also targeted his children and their Thai assets.

In response, a Cambodian official accused Thailand of long being a “central hub for transnational crimes” in Southeast Asia and “shifting blame” for the problem to Cambodia.

A spokesperson for Cambodia’s Senate also said the case against the senator was exaggerated and false, calling it an act of “revenge”. The senator himself did not respond to attempts by Cambodian media to reach him.

Although Thailand has ramped up efforts to tackle the scam industry in recent years, its leaders are likely using the issue to bolster public support at home, while bloodying the noses of Cambodian elites they allege are profiting from the industry.

Large operations continue to operate

Amid this war of words, Cambodian authorities insist the crackdown on the industry will continue.

To Cambodia’s credit, this latest campaign was national in scope, unlike previous crackdowns that were mostly confined to the coastal city of Sihanoukville, a major scamming hub.

Still, familiar patterns quickly began to surface. As in the past, the authorities have focused on small to mid-sized operations, while the largest operators seem to have been left untouched.

In many cases, these major compounds were reportedly tipped off in advance and evacuated. A significant number of scammers have since relocated to large compounds close to the Vietnam border, which seem to be operating without interference.

Indeed, one of us (Ling) joined a rescue team in early August trying to reach a Chinese man who claimed to have been trafficked into a compound hidden deep in the hills of Mondulkiri Province near the border.

The man couldn’t pinpoint his exact location, but through messages with the rescue organisation over several months, the team was able to gradually determine where he was being held – and the scale of the scamming enterprise.

Weeks after the crackdown, Ling joined the team on a field visit to assess the situation. From the hilltops at night, they saw lights flickering across the slopes coming from what appeared to be several buildings surrounded by sparse jungle.

With only one exposed access road to the site, the team couldn’t get close without being detected. But there was no doubt the compound was active and bustling, as were several others in the area that Ling observed on her trip.

The Chinese man was still inside at that time, but since then, there has been no word from him.

What needs to be done

Crackdowns on scam compounds have failed in the past because they don’t address the two fundamental pillars that allow the industry to flourish. One is the powerful local networks that protect scam operators. The other is the sophisticated physical infrastructure of the compounds.

As long as the elites who provide scam operators with cover remain untouched and the compounds remain intact, scammers can quickly get back to work when the pressure subsides.

Periodic crackdowns may shake things up temporarily, but the people being arrested tend to be low-level workers, not those at the top.

Once these campaigns are over, scamming activities simply restart. Operators may go quiet until the storm passes or move to safer locations. Confiscated equipment can be replaced, as can the workers.

The cycle can only be broken by longer-term measures to tackle the structural and systemic issues that prop up the industry in these countries, such as corruption and weak law enforcement.

Given the transnational nature of the industry and complicity of the authorities and elites in host countries, it also requires a more determined effort from global governments, law enforcement, and the finance and tech companies whose products and services are exploited by scam operators.

NASA plans to build a nuclear reactor on the Moon – a space lawyer explains why, and what the law has to say

Source: The Conversation – USA – By Michelle L.D. Hanlon, Professor of Air and Space Law, University of Mississippi

The first space race was about flags and footprints. Now, decades later, landing on the Moon is old news. The new race is to build there, and doing so hinges on power.

In April 2025, China reportedly unveiled plans to build a nuclear power plant on the Moon by 2035. This plant would support its planned international lunar research station.
The United States countered in August, when acting NASA Administrator Sean Duffy reportedly suggested a U.S. reactor would be operational on the Moon by 2030.

While it might feel like a sudden sprint, this isn’t exactly breaking news. NASA and the Department of Energy have spent years quietly developing small nuclear power systems to power lunar bases, mining operations and long-term habitats.

As a space lawyer focused on long-term human advancement into space, I see this not as an arms race but as a strategic infrastructure race. And in this case, infrastructure is influence.

A lunar nuclear reactor may sound dramatic, but its neither illegal nor unprecedented. If deployed responsibly, it could allow countries to peacefully explore the Moon, fuel their economic growth and test out technologies for deeper space missions. But building a reactor also raises critical questions about access and power.

The legal framework already exists

Nuclear power in space isn’t a new idea. Since the 1960s, the U.S. and the Soviet Union have relied on radioisotope generators that use small amounts of radioactive elements – a type of nuclear fuel – to power satellites, Mars rovers and the Voyager probes.

The United Nations’ 1992 Principles Relevant to the Use of Nuclear Power Sources in Outer Space, a nonbinding resolution, recognizes that nuclear energy may be essential for missions where solar power is insufficient. This resolution sets guidelines for safety, transparency and international consultation.

Nothing in international law prohibits the peaceful use of nuclear power on the Moon. But what matters is how countries deploy it. And the first country to succeed could shape the norms for expectations, behaviors and legal interpretations related to lunar presence and influence.

Why being first matters

The 1967 Outer Space Treaty, ratified by all major spacefaring nations including the U.S., China and Russia, governs space activity. Its Article IX requires that states act with “due regard to the corresponding interests of all other States Parties.”

That statement means if one country places a nuclear reactor on the Moon, others must navigate around it, legally and physically. In effect, it draws a line on the lunar map. If the reactor anchors a larger, long-term facility, it could quietly shape what countries do and how their moves are interpreted legally, on the Moon and beyond.

Other articles in the Outer Space Treaty set similar boundaries on behavior, even as they encourage cooperation. They affirm that all countries have the right to freely explore and access the Moon and other celestial bodies, but they explicitly prohibit territorial claims or assertions of sovereignty.

At the same time, the treaty acknowledges that countries may establish installations such as bases — and with that, gain the power to limit access. While visits by other countries are encouraged as a transparency measure, they must be preceded by prior consultations. Effectively, this grants operators a degree of control over who can enter and when.

Building infrastructure is not staking a territorial claim. No one can own the Moon, but one country setting up a reactor could shape where and how others operate – functionally, if not legally.

Infrastructure is influence

Building a nuclear reactor establishes a country’s presence in a given area. This idea is especially important for resource-rich areas such as the lunar south pole, where ice found in perpetually shadowed craters could fuel rockets and sustain lunar bases.

These sought-after regions are scientifically vital and geopolitically sensitive, as multiple countries want to build bases or conduct research there. Building infrastructure in these areas would cement a country’s ability to access the resources there and potentially exclude others from doing the same.

Critics may worry about radiation risks. Even if designed for peaceful use and contained properly, reactors introduce new environmental and operational hazards, particularly in a dangerous setting such as space. But the U.N. guidelines do outline rigorous safety protocols, and following them could potentially mitigate these concerns.

Why nuclear? Because solar has limits

The Moon has little atmosphere and experiences 14-day stretches of darkness. In some shadowed craters, where ice is likely to be found, sunlight never reaches the surface at all. These issues make solar energy unreliable, if not impossible, in some of the most critical regions.

A small lunar reactor could operate continuously for a decade or more, powering habitats, rovers, 3D printers and life-support systems. Nuclear power could be the linchpin for long-term human activity. And it’s not just about the Moon – developing this capability is essential for missions to Mars, where solar power is even more constrained.

A call for governance, not alarm

The United States has an opportunity to lead not just in technology but in governance. If it commits to sharing its plans publicly, following Article IX of the Outer Space Treaty and reaffirming a commitment to peaceful use and international participation, it will encourage other countries to do the same.

The future of the Moon won’t be determined by who plants the most flags. It will be determined by who builds what, and how. Nuclear power may be essential for that future. Building transparently and in line with international guidelines would allow countries to more safely realize that future.

A reactor on the Moon isn’t a territorial claim or a declaration of war. But it is infrastructure. And infrastructure will be how countries display power – of all kinds – in the next era of space exploration.

Jane Austen at 250: Why we shouldn’t exaggerate her radicalism

Source: The Conversation – Canada – By Kerry Sinanan, Associate Professor of Global pre-1800 Literature, University of Winnipeg

The BBC’s recent docuseries, Jane Austen: Rise of a Genius, the PBS mini-series Miss Austen as well as cultural and tourism festivities are all marking the 250th anniversary of Austen’s birth for a global audience.

Scholars have long noted Austen’s significant innovations with the novel form and enduring popularity.

Jane Austen: Rise of a Genius follows the 2023 BBC series Shakespeare: Rise of a Genius. Through the show’s titling and packaging, and by combining scholarly with popular commentary, the series promotes Austen as an authorial standard of modern literature.

It also sometimes presents her as socially subversive and a breaker of barriers, amplifying arguments that she was a “radical.”

The meaning of the word radical is to uproot and dismantle fundamental structures. Austen’s novels, skilful and absorbing as they are, offer no social or political revolutions: rather, they reform and realign Regency Britain, using the romance plot and its Cinderella template.

From my perspective as a professor of global pre-1800 literature who has studied narratives around the Black Atlantic, Caribbean slavery and race, what the series perhaps overlooks is that, in today’s context of Brexit, the politics of canon and tradition affirm a nationalist and neoimperial culture.


This article is part of a series commemorating the 250th anniversary of Jane Austen’s birth. Despite having published only six books, she is one of the best-known authors in history. These articles explore the legacy and life of this incredible writer.


Framing of slavery and empire

The series presents the 18th century as “booming” from the wealth of trade. While slavery and empire are mentioned in the first episode, the narration states slavery was being challenged by “progress and equality.”

Characterizing the Regency as a time for emerging progressive politics repeats colonial discourse and racial hierarchies, ignoring the fact that the high point of racism and British global empire in the Victorian era followed its slave-trading years. Enlightenment “progress” and abolitionism led to imperial domination.

As literary and cultural critic Edward Said explained, we should read the formation of the European “canon as a polyphonic accompaniment to the expansion of Europe.”

Said argues “imperialist discourse” in works by Austen and other canonical writers goes hand in hand with colonialism on the ground. Caribbean slavery is the backdrop for Mansfield Park, which sees Sir Thomas Bertram visit his plantations in Antigua to boost his profits.

As the BBC series acknowledges, Austen’s family benefited from slavery, as did many of her contemporaries, in an age when Britain dominated the slave trade.

The 250th birthday celebrations of Austen’s birth need to be read in the context of recreating a white, nationalist culture for a reactionary Brexit Britain, proud of its military Redcoats and imperial past — reflected in celebratory romance, afternoon tea, naval officers, muslin-gown esthetics and cosplay.

Characterization of the British Navy

One contributor to the BBC series is retired Royal Navy admiral Lord Alan William John West, a Labour Peer. He describes the British Navy of the time as “charting the world” and “leading scientific discovery,” uncritically deploying the language of colonial “discovery” and Enlightenment values.

This erases the Asian, African and Indigenous cultures that Britain colonized via trade monopolies, slavery, the East India Company and settler colonialism.

These histories have lasting legacies: West caused a furor in 2020 when he stated that asylum seekers crossing the English Channel in small boats should be put in “a concentrated place, whether it’s a camp or whatever.”

How the British government deploys its navy in the 21st century cannot be separated from ongoing colonial and nationalist actions.

‘Genius’ discourse

Jane Austen: Rise of a Genius touches upon Austen’s narrative innovation and importance (something intimated by literature scholar Paddy Bullard, who states there was writing before Austen and after Austen). Through the “genius” title and some “genius” commentary, the series appears to twin this analysis with the suggestion that Austen was counter-cultural.

Well-known author Helen Fielding (Bridget Jones’s Diary) describes Austen as a “genius” and the term is used by other writers, too.

The label “genius” perpetuates racist 18th-century Chain of Being discourses that placed white people at the top of a racialized hierarchy of being and Black people at the bottom. In 1774’s An History of the Earth and Animated Nature, Oliver Goldsmith concluded “man is naturally white.”

“Genius” is an ableist concept based in post-Darwinian eugenics and suggests a connection between supposed intelligence and evolution.

Austen and conservative social roles

One of the most prominent literary critics of Austen, British scholar Marilyn Butler, argued in Jane Austen and the War of Ideas that Austen’s novels confirm conservative roles for women in society, emphasizing “self-abnegation” and duty, and that she refused radical, Jacobin ideas of equality and political revolution.

Indeed, while a multiplicity of perspectives can be read in Austen, the structures of Austen’s plots ultimately affirm a conservative social and political order.

Far from being subversive, Austen, via alluring romance plots, massages her class-structured society into accepting the lower gentry and trading class, such as the Bennets and Gardiners in Pride and Prejudice.

Reading Austen and slavery

As I have argued, Darcy is not only an ideal romantic hero, but an ideal Briton at the heart of empire, ready to anchor the landed ancien régime of England as it moved into the burgeoning era of global domination, with a morality rooted in Protestant supremacy.

In the series, Bullard describes Austen as a “fan” of abolitionist Thomas Clarkson, and Austen biographer Paula Byrne reads Mansfield Park as a “serious” engagement with the “shadows” of slavery and “women’s suppression.”

Yet, while slavery is alluded to, the novel is not clearly anti-slavery. In Mansfield Park Austen offers a careful satire of an enslaving family, but one that positively secures the Bertrams’ place in society, merely amending their values.

Recent scholarship that uncovered how Austen’s brothers participated in the abolition movement after her death suggests Austen may have been on her way to becoming a public abolitionist.

However, this is speculative: while many women writers such as Hannah More and Anne Yearsley wrote explicitly anti-slavery pieces, Austen was not a public abolitionist.

Slavery suffused Romantic literature. At a time abounding with radical writers and anti-slavery pamphlets, poems and tracts, including those written by formerly enslaved people such as Olaudah Equiano and Ottobah Cugoano, the fact that Austen — like her contemporaries — became increasingly aware of the inhumanity of the Middle Passage is not saying much.

Perpetuating myth

Suggesting Mansfield Park deeply treats aspects of slavery or women’s suppression glosses over the legal realities of chattel slavery. Under English colonial law, enslaved women’s children were transformed into legal property.

Women in 18th-century Britain had limited rights, but as Austen’s novels illustrate, they were not legal property. We follow her heroines taking their desired places, including Fanny Price, in securing a culture of white, male inheritance.

Austen was a compelling innovator of the novel form. Presenting her as radical and a genius misunderstands her art and misrepresents the imperial culture that she was part of, instead perpetuating new myths of a British literary canon.

It’s challenging to predict extreme thunderstorms — improving this will help reduce their deadly and costly impacts

Source: The Conversation – Canada – By David Sills, Director, Northern Tornadoes Project, Western University

Our ability to predict extreme weather from thunderstorms, like the recent catastrophic flash floods in Texas, is unsettlingly poor, even in the hours leading up to the event. Improvements in understanding, detecting and predicting extreme thunderstorms — and increasing community resilience to them — are badly needed.

The anatomy of a flash flood: Why the Texas flood was so deadly


Severe thunderstorms are a regular aspect of summer weather in Canada. A severe storm becomes extreme when the intensity of a thunderstorm hazard (tornado, downburst, damaging hail or flooding rains) escalates to a level rarely observed. Or, when the impacts of a storm are extreme due to enhanced exposure and vulnerability, resulting in significant casualties and economic losses. In some cases, both intensity and impacts are extreme.

Footage from The Weather Network of flooding in Calgary in July 2025.

At the new Canadian Severe Storms Laboratory at Western University, we’re exploring how to understand and reduce risks produced by extreme weather. Research projects include the Northern Tornadoes Project, the Northern Hail Project, the Northern Mesonet Project and an upcoming project focusing on thunderstorm flash flooding.

Extreme storms

We compiled a list of the top 10 worst natural disasters in Canada, ranked by insured losses over the last 20 years. While the 2016 fire that devastated Fort McMurray, Alta., tops the list, half of the events are associated with extreme thunderstorms.

This includes two Calgary-area hailstorms in 2020 and 2024, the Ontario-Québec derecho of 2022 and two Toronto-area flash floods (2024 and 2013). Each of these disasters cost close to $1 billion or more in insured losses.

One commonality among these events is that on the morning of the extreme event, there was little to no indication that an extreme thunderstorm would occur. In fact, in each case, it was not clear even during the storm that an extreme event was underway. Clearly, this affects the accuracy, timeliness and urgency of weather alerts meant to keep people safe.

Another commonality is that extreme thunderstorms can have a very short “fuse.” Unlike heat waves, droughts and other larger-scale phenomena, the threat due to thunderstorm-related extreme weather can increase suddenly.

Risk assessment and unreasonable data

A simple model of risk is “hazard” x “vulnerability”, which means that the risk to people and property can be determined based on both the type, intensity and coverage of a dangerous weather phenomenon and the ability of households and infrastructure to cope with and recover from the hazard’s harmful impacts.

Weather forecasters are trained to analyze and synthesize all available meteorological data to identify the most likely future state of the atmosphere and any related risks.

This often involves dismissing extreme outliers — if the numerical weather prediction (NWP) models are even able to predict them — and focusing on more plausible forecasts. Weather observation networks are also not optimized for extreme weather; sometimes, critical data are lost in power outages or are suppressed because they go beyond what is deemed reasonable.

With the 2013 Toronto flood, for example, even cutting-edge NWP models using a variety of different approaches were unable to reproduce the focused rainfall that resulted in the flash flooding. Future NWP models need to be optimized for handling such extreme events.

Extreme impacts

On the vulnerability side of the equation, it is rarely clear where exactly a storm — be it severe or extreme — will hit, even just hours before. If it affects a vulnerable area, like a tornado hitting tightly packed homes in a subdivision or heavy rain affecting a campground surrounded by steep terrain, then impacts are likely to be extreme.

So what actions are required to optimize detecting, forecasting and alerting for extreme thunderstorms? First, a more sophisticated model of risk might be:

risk = (hazard x vulnerability x exposure) / resilience

This helps to further refine the risk.

To enhance our ability to detect, predict and alert for extreme thunderstorm hazards, we need to develop techniques and tools to better identify situations where the outlier solution may be plausible or even realistic, given the conditions.

This is required both for NWP models that are increasingly used for forecasting, and for observation networks such as weather stations and radars that can indicate to a forecaster that a warning is needed immediately.

To know where hazards occur most frequently, we need to know the hazard’s climatology — the locations where it is strongest or occurs most frequently. This requires collecting vast quantities of data, assessing the intensity of hazards and ensuring the quality of the data. Improved data will allow decision-makers to minimize costs, ensuring that the benefits of the measures outstrip the costs.

Improved knowledge about community vulnerability is also important. Up-to-date flood maps are critical for understanding how heavy rain may turn into disastrous flash flooding, for example. However, preparing a community for an event having an intensity it has never experienced before is an additional challenge.

Resilient communities

As urbanization continues and cities grow outward, exposure to hazards is increased. What were once fields or flatlands become vulnerable residential or industrial developments.

Communities can improve their resilience to extreme thunderstorms through short-term coping tactics and longer-term adaptive strategies — particuarly as weather extremes in general increase due to climate change.

Overall, improving our ability to detect, predict and alert for extreme thunderstorms — and increase community resilience to them — is a massive undertaking. It is essentially a community endeavour that requires the efforts of academia, governments, industry, emergency managers and the public. The ultimate goals are to prevent casualties, and to keep people in their homes and keep schools and businesses open, following extreme thunderstorm events.

‘Stop Killing Games’: Demands for game ownership must also include workers’ rights

When French video-game publisher Ubisoft announced it was shutting down servers for The Crew, a popular online racing game released in 2014, it wasn’t just the end of a title. It marked the beginning of a broader reckoning about the nature of digital ownership, led by players angry at the company’s decision to deny them something they had paid for.

The Stop Killing Games (SKG) movement was born from that moment. As of July 2025, it has gathered more than 1.4 million signatures through the European Citizens’ Initiative. The European Commission is now obliged to respond.

At the heart of the issue is a deceptively simple question: when we buy a video game, what are we actually purchasing? For many gamers, the answer used to be obvious. A game was a product, something you owned, kept and could return to at will.

However, live service games have changed that dynamic. These are games usually played online with others and that typically require subscriptions or in-game payments to access features or content. They include popular titles such as Fortnite, League of Legends and World of Warcraft.

With live service games, players are learning that what they’ve really bought is something more tenuous: access.

And, evidently, access is something that can be revoked.

Erasing gaming communities

The issue goes well beyond The Crew. In the last couple of years alone, several games have been shut down, including Anthem, Concord, Knockout City, Overwatch 1, RedFall and Rumbleverse.

There are valid reasons why companies might choose to end support for a title. The game industry is saturated and brutally competitive. Margins are tight, player expectations are high and teams often face impossible deadlines. When an online game underperforms, a publisher will likely be inclined to cut their losses and shut it down.

Games tend to accumulate bugs in their code that are complex to clean and create player dissatisfaction. In our research, we have shown that when a game underperforms or becomes too costly to maintain, shutting it down can be a rational, even reparative, decision on many levels.

Yet, when companies decide to shut down a live service game’s servers, it’s not just content that vanishes. So do the communities built around it, the digital assets (costumes, weapons and so on) players have earned or paid for and the sometimes hundreds of hours invested in mastering it. In the blink of an eye, the game is gone, often without recourse or compensation.

That’s not just a customer service issue; it’s a cultural one.

Games are not just another type of software. They are creative works that can foster shared experiences and vibrant communities.

Players don’t just consume games, they inhabit them. They trade stories, build friendships and express themselves through digital spaces. Turning those spaces off can feel, to many, like erasing a part of their lives.

This profound disconnect between business logic and player experience, which we theorized in the past, is what gave rise to the SKG movement. Video game publishers failed to anticipate the cultural backlash triggered by these shutdowns.

What regulators can do

Players of shut-down games may believe they were misled and should be compensated. Unfortunately, the current system offers little transparency and even less protection for them.

That’s where regulation can help. The European Commission now has a chance to provide much-needed clarity on what consumers in the European Union are actually buying when they purchase live service games.

A good starting point would be requiring companies to disclose whether a purchase grants the buyer ownership or limited access, akin to recent legislation passed in California.

Minimum support periods, clearer content road maps (the projected updates) and making companies create mandatory offline versions for discontinued online games might also help prevent misunderstandings.

There’s room for creativity here, too. Rather than killing a game outright, companies could allow player communities to take over its maintenance and allow for the continued creation of new content, especially for titles with active fan bases.

This is known as “modding,” and in some cases, community-led revivals have even inspired publishers to re-release enhanced editions years later.

Developers need protections too

There’s another part of this story that’s unfortunately overlooked: the people who make these games. Video game developers are regularly subjected to long hours, poor conditions and toxic workplace cultures in order to meet the demands of continuous live service updates.

In our research, we’ve found that this new model of endless content creation and perpetual support is unsustainable, not just financially or technologically, but humanly.

Instead of periodically “crunching,” live service game developers are now constantly “grinding.” Somehow, in an industry notoriously demanding for workers, this model has managed to make things even worse.

Policymakers need to protect both players and the workers creating games. That means, among other things, rethinking release schedules, enforcing rest periods for development teams and holding companies accountable for the well-being of their staff. The overall health of the industry depends on it.

Whether you support the SKG movement or not, the issues it raises are urgent. While the ownership question is a very legitimate one, video game developers deserve more care and protection.

The European Commission’s response could help define the future of digital ownership, cultural preservation and ethical labour in gaming.
