Si les technologies immersives, telles que les casques de réalité virtuelle ou les dispositifs de réalité augmentée, sont souvent associées aux loisirs, elles jouent aussi un rôle dans divers secteurs professionnels. Dans le domaine de la santé, leurs progrès renouvellent en particulier les protocoles de rééducation.


Réalité virtuelle, réalité augmentée, réalité mixte… Ces nouvelles technologies permettent d’immerger les utilisateurs dans des environnements numériques interactifs. Au cours des deux dernières décennies, ces technologies ont connu un très fort développement résultant des avancées combinées de l’électronique et de l’informatique.

Regroupées sous l’appellation de « réalité étendue » (« extended reality » en anglais, abrégé XR), ces technologies sont souvent associées au secteur du divertissement. Pourtant, elles sont aussi très largement utilisées dans les milieux professionnels, qu’il s’agisse de former ou d’entraîner des opérateurs ou pilotes de véhicules particulièrement quand ils se préparent à exercer dans des milieux difficiles ou dangereux, mais aussi pour développer de nouvelles approches pédagogiques à travers ce que l’on appelle les « serious games ».

Ces technologies s’invitent également dans le secteur de la santé pour aider, par exemple, les chirurgiens dans leurs interventions. Elles s’avèrent aussi très intéressantes en matière de rééducation motrice dans le but d’améliorer la récupération des patients de tous âges, atteints de maladies ou de lésions neurologiques à l’origine de limitations fonctionnelles importantes.

Amener le virtuel dans le domaine la rééducation motrice

En France, environ 140 000 personnes sont victimes chaque année d’accidents vasculaires cérébraux, 150 000 subissent un traumatisme crânien, tandis que 25 000 nouveaux cas de maladie de Parkinson et 1 500 cas de paralysie cérébrale sont diagnostiqués.

Ces problèmes majeurs de santé se traduisent pour les enfants, adolescents ou adultes concernés par des altérations de leur motricité qui peuvent affecter la posture, les déplacements locomoteurs ou encore les actions des membres supérieurs. La rééducation est alors essentielle, car elle favorise la restauration de tout ou partie de ces fonctions motrices. Elle vient stimuler les mécanismes de plasticité cérébrale qui permettent des récupérations fonctionnelles parfois très importantes.

Ainsi, lorsque le cerveau subit certains dommages, les structures cérébrales ont un fort potentiel de réorganisation et de restauration des fonctions qui ont pu être altérées. Ce potentiel s’exprime d’autant plus quand la rééducation démarre tôt, de manière adaptée et progressive.

Qu’est-ce que la plasticité cérébrale ?


Dans un tel contexte, et afin d’offrir aux patients les meilleures chances de récupération, les thérapeutes ont pu développer une grande gamme de protocoles de rééducation. Les techniques conventionnelles employées dans la rééducation motrice présentent cependant parfois certaines limites ou contraintes pour les patients. Ainsi, la longueur et la répétitivité des séances peuvent par exemple provoquer fatigue, douleur et démotivation.

À cela s’ajoute une autre difficulté : ces méthodes proposent généralement des exercices de motricité assez éloignés des besoins du quotidien. Cet éloignement entre la rééducation et les interactions requises dans les situations de tous les jours peut expliquer certaines difficultés de transposition et de maintien des améliorations obtenues lors des protocoles de rééducation.

Les recherches menées pour mettre au point des méthodes complémentaires ou alternatives aux techniques de rééducation existantes ont identifié l’usage des technologies de réalité étendue (XR) comme l’une des alternatives les plus intéressantes.

Ces technologies permettent de proposer aux patients des protocoles de soin avec des conditions contrôlées, progressives et attractives. Alors que les méthodes traditionnelles sont souvent fondées sur l’exécution de mouvements répétitifs et décontextualisés, ces technologies permettent de solliciter des actions finalisées, c’est-à-dire orientées vers un but concret. L’efficacité de la rééducation est de ce fait augmentée, et l’on constate une amélioration de la transférabilité des bénéfices vers les activités du quotidien.

Des premiers essais fondés sur des jeux commerciaux

Les premiers essais pour introduire les dispositifs numériques interactifs dans les centres de rééducation ont été réalisés essentiellement avec des systèmes de jeux vidéo disponibles dans le commerce, tels que les consoles de jeu PlayStation et caméra EyeToy, Xbox et caméra Kinect ou Nintendo Wii et caméra IR Pix Art. Ces systèmes de jeux nécessitent de produire des actions motrices plus ou moins complexes qui sont captées par les caméras et retranscrites sous différentes formes dans le jeu (déplacement d’un personnage, pilotage d’un véhicule, lancement de balles, etc.).

Dans la plupart des cas, l’usage de ces jeux vidéo s’est révélé bénéfique pour la rééducation. En effet, des études ont montré que ces bénéfices étaient liés aux interactions motrices requises dans un cadre ludique permettant de maintenir dans la durée la motivation des patients.

Toutefois, les possibilités d’adaptation de ces jeux aux capacités des patients sont souvent très limitées dans la mesure où ils n’ont pas été conçus dans ce but. Il en est de même pour leur intégration dans des protocoles de rééducation quantifiés, car ils ne permettent pas d’effectuer le suivi des patients et d’identifier finement la nature des progrès réalisés. Pour ces raisons, de nouvelles propositions de jeux spécifiques à la rééducation motrice ont émergé, faisant appel aux diverses technologies de la réalité étendue.

Réalité étendue, virtuelle, augmentée ou mixte : de quoi parle-t-on ?

Le concept de réalité étendue recouvre plusieurs technologies : réalité virtuelle, réalité mixte et réalité augmentée.

La réalité virtuelle plonge entièrement l’utilisateur dans un monde numérique, par l’intermédiaire de casques dotés de deux mini-écrans (un pour chaque œil). Ceux-ci permettent de percevoir l’environnement numérique en stéréo, et donc en 3D. Les casques sont également équipés de capteurs permettant de détecter les mouvements de la tête pour une mise à jour en « temps réel » des images projetées, ce qui permet l’exploration du monde virtuel dans toutes les directions. Les interactions avec ces environnements numériques sont rendues possibles par l’utilisation d’interfaces connectées telles que des manettes de contrôle, des marqueurs placés sur le corps ou encore des gants d’interaction.

La réalité mixte, quant à elle, projette des espaces numériques dans un environnement réel bien visible. Les systèmes les plus immersifs permettent des projections sur des écrans multiples situés tout autour de la personne immergée (y compris au-dessus et en dessous d’elle).

Enfin, la réalité augmentée ajoute des éléments numériques dans le monde réel. Cette technologie peut utiliser des lunettes permettant la surimpression d’éléments numériques dans la scène visuelle réelle. Elle peut aussi recourir à une caméra qui filme l’environnement et le projette sur un écran, où sont ajoutés les éléments numériques. Cela est généralement réalisé dans un casque, tel que ceux utilisés pour les applications de réalité virtuelle, mais cela peut aussi se faire via un téléphone ou une tablette numérique.

Des jeux en réalité virtuelle spécifiques à la rééducation

S’inspirant des jeux vidéo, des dispositifs de réalité virtuelle ont récemment été développés avec l’appui de thérapeutes pour s’adapter spécifiquement au contexte de la rééducation et aux besoins des patients. Ces dispositifs intègrent par exemple des principes de progressivité : ils font varier la difficulté ou l’intensité des exercices, leur fréquence ou leur répétition pour atteindre au mieux les objectifs thérapeutiques.

L’un des atouts de la réalité virtuelle est qu’elle favorise l’implication dans la rééducation, en raison du « sentiment de présence » qu’elle génère, grâce à l’utilisation de casques immersifs.

Dans ces jeux de rééducation, la finalité des actions est prépondérante. Elle permet de donner à la rééducation davantage de sens, et une attractivité nouvelle. Le patient se rééduque progressivement, par des mouvements ayant un but précis : en atteignant des objets, en les utilisant, en adoptant des postures spécifiques ou encore en se déplaçant dans un parcours guidé. Cette finalisation des actions a pour but de favoriser des transferts plus rapides vers les activités du quotidien (par exemple cuisiner, ranger une pièce, jardiner, etc.). Les progrès réalisés sont quantifiés en matière d’amplitude, de fluidité, de vitesse et de précision des mouvements réalisés.

Le projet FarmaDay illustre bien cette approche. Cette application de neuroréhabilitation est destinée à rééduquer les membres supérieurs à travers des activités de la vie quotidienne en réalité virtuelle gamifiée avec l’utilisation de casques immersifs. Ce système place le patient dans un environnement virtuel reproduisant une ferme. Les patients peuvent l’explorer en y effectuant diverses tâches : s’occuper des animaux, cueillir des fruits ou des légumes, se laver les mains, verser une boisson ou encore jouer du piano.

Dépasser certaines craintes dues aux pathologies

Chez certains patients, les limitations fonctionnelles et la douleur peuvent être très intériorisées. Cela se traduit par une diminution de l’activité et de l’implication dans l’action, par crainte d’avoir mal, de se blesser à nouveau ou de ne pas y arriver. Cette « kinésiophobie » peut freiner la rééducation et contribuer à renforcer les limitations fonctionnelles.

Un des avantages de la réalité virtuelle totalement immersive est d’impliquer fortement les patients dans leur rééducation. Équipés d’un casque immersif, ils ne voient pas leur propre corps, mais seulement des représentations virtuelles de celui-ci (avatars), ce qui peut les aider à dépasser certaines de leurs craintes.

Autre intérêt de la rééducation en réalité virtuelle : la possibilité de créer des exercices dans lesquels les mouvements à produire et l’atteinte des buts recherchés sont guidés par différentes modalités sensorielles (visuelles, sonores, tactiles). Certains objets peuvent par exemple être mis en surbrillance quand le mouvement d’atteinte est réussi. Des guides ou des feed-back de trajectoires de mouvement, de direction, de rythme, peuvent être affichés, ainsi que des codes couleurs, des sons, des vibrations, ou encore des indications ou des commentaires sur les performances à réaliser.

À titre d’exemple, le projet RV-Reeduc réalisé au sein du laboratoire GREYC] de l’Université de Caen Normandie, a abouti au développement de jeux de poursuite et d’atteinte de cibles en mouvement, dans un environnement virtuel 3D avec casque immersif (voir vidéo présentée ci-dessous dans le cadre du projet Neo-Reeduc).

Proposés dans des centres de rééducation pour des enfants et adolescents atteints de paralysie cérébrale, ces jeux de rééducation ont permis d’améliorer les amplitudes, la fluidité et la précision des mouvements des jeunes patients, après un programme de trois séances hebdomadaires sur une durée d’un mois. Les effets bénéfiques se sont avérés durables, puisqu’ils étaient encore observés trois mois après la fin de la rééducation.

Des alternatives pour dépasser certaines limites de la réalité virtuelle

Si la réalité virtuelle a de nombreux avantages pour la rééducation motrice, elle présente aussi certains inconvénients. Ainsi, certains patients peuvent ressentir un inconfort lié au poids du casque ou à la sensation d’isolement qu’il induit. De plus, certains d’entre eux peuvent ressentir une appréhension, un déséquilibre ou un malaise proche du mal des transports ou cinétose, en particulier lorsque des déplacements sont requis.

Ce type de « cybermalaise » est le plus souvent dû à l’amplification des mouvements réalisés du réel en virtuel. Cette amplification des déplacements crée un décalage entre les perceptions corporelles et les perceptions visuelles. Il peut aussi être lié au décalage, même très faible, du « temps réel » dans la mise à jour des images visuelles, par rapport aux signaux de mouvements perçus par le corps. Ces phénomènes, appelés « incongruences » ou « conflits sensoriels », peuvent provoquer des symptômes désagréables tels que des maux de tête, des vertiges, voire des nausées et des vomissements.

L’immersion dans un monde virtuel doit donc se faire de manière progressive. Elle n’est pas forcément appropriée à tous les patients, notamment ceux qui présentent des troubles perceptifs. Pour pallier ces inconvénients, d’autres projets ont choisi de s’appuyer sur la réalité mixte, qui fusionne les mondes physique et numérique.

C’est le cas du projet Neo-Reeduc, piloté lui aussi par le laboratoire GREYC. Les jeux de rééducation créés en partenariat avec la société NeoXperiences se situent en réalité mixte. Les images sont projetées sur de grands murs interactifs, et les mouvements des utilisateurs, capturés grâce à un système vidéo (« motion capture »), permettent d’interagir avec les applications. Ainsi, plus besoin d’équiper les patients de casques, manettes de contrôles ou autres dispositifs corporels.

Une telle immersion en réalité mixte rend aussi possible l’implication de plusieurs utilisateurs, ce qui favorise les échanges et renforce les aspects ludiques et conviviaux des exercices, créant un environnement susceptible d’augmenter la motivation des patients à suivre la rééducation.

Perspectives de développements futurs

Les protocoles faisant appel aux nouvelles technologies de réalité étendue (XR) permettent de stimuler de manière plus précise, plus douce et plus progressive les fonctions motrices ayant subi des atteintes. Elles rendent la rééducation plus ludique et davantage finalisée, tout en renforçant la motivation des patients et leurs interactions sociales.

Ce faisant, ces technologies contribuent à diversifier et augmenter le volume de rééducation, en augmentant ainsi le potentiel de plasticité cérébrale. Cela permet d’élargir les répertoires des thérapeutes dans leurs protocoles de rééducation motrice pour une meilleure récupération fonctionnelle.

Des recherches complémentaires associant patients, thérapeutes, chercheurs et développeurs sont cependant encore nécessaires afin de mesurer plus finement l’efficacité de ces dispositifs de rééducation innovants. Il reste en effet à identifier plus précisément les facteurs pouvant générer des effets bénéfiques et ceux pouvant causer des effets indésirables. Enfin, il reste à explorer la possibilité d’utiliser des interfaces de plus petite dimension (tablettes graphiques et smartphones) qui pourraient permettre à terme la poursuite de la rééducation à domicile.

Votre alimentation influence-t-elle vos rêves ? Ce que disent nos recherches sur la nourriture et les cauchemars

Source: The Conversation – in French – By Jade Radke, PhD Student, Behavioral Sustainability Lab, University of British Columbia

Vous êtes-vous déjà demandé si un rêve étrange était dû à quelque chose que vous aviez mangé la veille au soir ? Si oui, vous n’êtes pas seul. Nous faisons tous des rêves étranges de temps en temps et cherchons à comprendre pourquoi.

Depuis des siècles, on croit que l’alimentation et l’heure du repas influencent les rêves. Un exemple frappant se trouve dans la bande dessinée du début du XXe siècle intitulée Dream of the Rarebit Fiend (Rêve d’un fondu de fondue, en français), dans laquelle les personnages attribuent souvent leurs rêves étranges au fait d’avoir mangé un plat à base de fromage, comme le Welsh rarebit, la veille au soir.

Malgré ce folklore, les recherches scientifiques sur le lien entre alimentation et rêves restent limitées.

Quelques enquêtes exploratoires ont donné des résultats préliminaires et suggestifs. Une étude de 2007 a révélé que les personnes qui consommaient davantage d’aliments biologiques affirmaient faire des rêves plus vivants et plus étranges que celles qui consommaient davantage de restauration rapide.

De même, une enquête de 2022 a montré que certains aliments influencent les rêves : fruits pour des souvenirs plus fréquents, fruits et poisson pour des rêves lucides, sucreries pour davantage de cauchemars. Et dans notre étude de 2015, nous avons constaté que près de 18 % des participants pensaient que leur alimentation influençait leurs rêves. Parmi eux, les produits laitiers étaient les plus souvent cités comme responsables.

Dans le prolongement de cette étude, nous avons récemment mené une enquête en ligne auprès de 1082 étudiants canadiens en psychologie, auxquels nous avons posé des questions sur leurs habitudes alimentaires, leur état de santé général, la qualité de leur sommeil et leurs rêves. Nous avons testé plusieurs hypothèses sur la façon dont l’alimentation et les sensibilités alimentaires pourraient influencer les rêves, y compris leur influence possible sur la gravité des cauchemars.

Ce que nous avons découvert

Un peu plus de 40 % des participants nous ont dit que certains aliments aggravaient ou amélioraient la qualité de leur sommeil. Environ 5 % pensaient que l’alimentation avait une incidence sur leurs rêves, les desserts, les sucreries et les produits laitiers étant les coupables les plus fréquemment cités.

Les personnes allergiques ou intolérantes au gluten percevaient davantage que l’alimentation influençait leurs rêves. Celles intolérantes au lactose signalaient plus souvent que certains aliments perturbaient leur sommeil.

Nous avons également constaté que les participants souffrant d’une allergie alimentaire ou d’une intolérance au lactose signalaient des cauchemars plus fréquents et plus intenses. La fréquence des symptômes gastro-intestinaux, comme les douleurs abdominales et les ballonnements, était associée à la fois à l’intolérance au lactose et aux cauchemars, ce qui pourrait expliquer ce lien.

Ces résultats confirment un nombre croissant de preuves suggérant un lien entre le microbiome intestinal et le système nerveux central (l’axe intestin-cerveau). Pour la première fois, ils révèlent que les troubles intestinaux peuvent se manifester psychologiquement pendant le sommeil sous forme de cauchemars.

Cela rejoint les recherches en cours sur la relation entre l’alimentation et le syndrome de stress post-traumatique (SSPT), dont l’un des symptômes est la fréquence des cauchemars. Alors que travaux se sont concentrés sur la relation entre les habitudes alimentaires globales et le SSPT, nos résultats suggèrent que certains aliments spécifiques, tels que les produits laitiers et les sucreries, pourraient exacerber les cauchemars en particulier.

Dès lors, les traitements du SSPT pourraient gagner à inclure une évaluation des habitudes alimentaires, des allergies et des intolérances, ainsi que des changements de régime.

Nos recherches montrent un lien possible entre alimentation et rêves, mais les résultats restent corrélationnels. Des expériences sont nécessaires pour tester dans quelle mesure certains aliments peuvent avoir un impact sur les rêves.

Les prochaines étapes pourraient consister en expériences contrôlées pour tester l’effet de certains aliments déclencheurs, tels que du fromage contenant du lactose par opposition à du fromage sans lactose, en particulier chez les personnes intolérantes au lactose ou qui font fréquemment des cauchemars. Des expériences similaires pourraient être menées auprès de participants souffrant de divers types d’allergies alimentaires.

Quelques conseils pratiques

Nos résultats, corroborés par des recherches antérieures, suggèrent quelques mesures simples pour mieux dormir et rêver :

  1. Évitez de manger tard le soir, en particulier des aliments lourds, sucrés ou épicés. Nous avons constaté que manger le soir était associé à des rêves troublants et à une moins bonne qualité de sommeil.

  2. Si vous êtes intolérant au lactose, essayez d’éviter les produits laitiers avant de vous coucher ou optez pour des alternatives sans lactose. Par exemple, les fromages à pâte dure et affinés ont tendance à contenir moins de lactose que les fromages à pâte molle et frais.

  3. Si vous souffrez d’allergies alimentaires, pensez à réduire votre consommation d’aliments concernés avant de vous coucher. Les inquiétudes liées à d’éventuelles réactions allergiques pourraient s’immiscer dans vos rêves.

  4. Notez tous les aliments qui semblent influencer votre sommeil ou vos rêves, et essayez de les supprimer pendant des périodes intermittentes pour voir s’ils ont une incidence sur la qualité de votre sommeil ou de vos rêves.

En général, une alimentation équilibrée et riche en nutriments, comprenant des fibres, des fruits, des légumes et des protéines maigres, peut contribuer à améliorer la qualité du sommeil ou des rêves. Le principal enseignement à retenir ? Écoutez votre corps : si certains aliments ou habitudes perturbent vos nuits ou provoquent régulièrement de mauvais rêves, adaptez‑les en conséquence.

Scary stories for kids: Watership Down made me aware of my mortality at age four

Source: The Conversation – UK – By Aislinn Clarke, Lecturer in Film Studies, Queen’s University Belfast

When I think of my first encounter with horror, I don’t think of a vampire, a witch, or even a possessed girl’s head spinning round (I saw The Exorcist at the age of seven). I think of a Sun God, I think of teeth and claws slicked with blood, I think of the Black Rabbit of Death. And he wasn’t even the bad guy.

I’m not talking about some campy folk horror from the 1960s. I’m talking about the 1978 animated version of Richard Adams’ Watership Down.

I was perhaps four when I saw it. The opening sequence remains a core memory: the myth of the Prince with a Thousand Enemies, the Original Rabbit, rendered in gorgeous animation that evoked Aboriginal art via the films of New Zealand artist Len Lye. Then the great crimson wave of blood flowing across the fields. Death, cold and indiscriminate, was coming to the gentle slopes of Watership Down.

That was the moment I first felt awe and terror at the fragility of life. And the utter indifference of death. The kind of awe and terror we assume children’s minds can neither comprehend nor bear.

And that was just the beginning.


This article is part of a series of expert recommendations of spooky stories – on screen and in print – for brave young souls. From the surprisingly dark depths of Watership Down to Tim Burton’s delightfully eerie kid-friendly films, there’s a whole haunted world out there just waiting for kids to explore. Dare to dive in here.


It’s easy to assume that because Watership Down is a cartoon about woodland animals, it must be gentle. It isn’t. And that’s why it’s so powerful. My parents had already let my older siblings and I watch the campy spectacle of Hammer Horror at Halloween, but they couldn’t have guessed the deeper impact of Adams’s rabbits – they let me watch alone from the safe distance of the shag rug one sunny afternoon in 1984.

Nothing terrible had yet happened to me. I hadn’t known grief or loss. Watership Down cracked that open. For the first time, I understood, viscerally, that all the earth’s creatures – including myself – are mortal, and that death was coming for us all.

But don’t let that put you off sharing it with your four-year-old.

The value of horror is that it gives us a safe space to process fear. It takes the anxieties we can’t name and turns them into something we can face. I watched horror films with my family every weekend – Poltergeist, Day of the Dead, The Evil Dead.

Afterwards I slept like the actual dead. Soundly. Peacefully. I didn’t have nightmares, even if I did dream of rabbits. I didn’t need nightmares. For, what is a horror film, after all, if not a nightmare you share with people you love – a nightmare that can be switched off and tucked back into its case?

And, yes, I am saying that Watership Down is a horror film. Like Lovecraft’s cosmic horror, like The Thing or Alien, the terror of Watership Down arises from mortal insignificance. We too are small, powerless, unmoored, no different to the rabbits fleeing the down.

The film’s horror depends on empathy, the recognition that every creature wants what we want: to live, to love, to survive. Children understand that we are not special.

However, it is perhaps the most primal and defining characteristic of humanity that, not only do we fear death, but we know it is coming. Such darkness is part of being human and we can’t insulate children from the fullness of being human.

If we try, the chances are that the darkness will come out anyway in their nightmares, understood as a terrible thing that their own mind created in the dead of night. To share a film like Watership Down with them is to say: “I trust you with this. You are ready for awe, wonder, and yes, for fear too. And it is because we fear that we hope.”

Richard Adams opened his novel with a gruesome quote from the ancient Greek tragedian Aeschylus and added: “If that makes the child put it back on the shelf, then to Hell with the child.”

His provocation was not contempt but a refusal to patronise. Children, he argued, deserve stories that take them seriously. Indeed, to live without curiosity, without discomfort, without provocation, is the stuff of nightmares. That is hell.

Both the book and the film trust their audience to confront mortality honestly. That trust makes for stronger children – and stronger adults. Adams rejected allegorical readings of his story, insisting that this gut wrenching heroes’ journey, with its keen sense of justice, really was about rabbits.

Children understand that not everything has to be about us. Only adults insist on being the default main character. Children know that in this beautiful, terrible world, everything – even us – just wants to live.

Perhaps all of this is more than one would expect from a cartoon film about woodland animals. Maybe we could all use a sunny afternoon on the rug, watching Watership Down, and remembering what it is like to be small and afraid and full of hope.


Watership Down has a PG rating, which means some material may not be suitable for young children, so parental guidance is advised.

Rise in youth mortality fuelled by mental illness, drugs, violence and other preventable causes

Source: The Conversation – UK – By Manuel Corpas, Lecturer in Genomics, University of Westminster

In some regions, youth mortality has actually risen in the past decade. KieferPix/ Shutterstock

Global mortality continues to fall. Life expectancy has improved to unprecedented levels and deaths in young children have plummeted. Yet for adolescents and young adults, especially those aged 15 to 24, little progress has been made according to data from the latest Global Burden of Disease study. In parts of North America and eastern Europe, mortality in those aged 15-24 has actually risen in the past decade.

This latest study also showed the main causes of death among young people aren’t disease or poor health. The main causes were shown to be injury, violence, suicide, road traffic accidents and substance abuse.

This shows us that health systems worldwide are still ill-equipped to prevent or intervene effectively in social and structural causes of youth mortality.

The Global Burden of Disease study is one of the largest studies on the picture of health, disease and mortality worldwide. The study analysed more than 310,000 data sources collected between 1950 and 2023 from 204 countries. Using death registries, censuses and household surveys, the research team estimated age-specific mortality trends across the lifespan.

The overall picture is one of uneven progress.

For children, especially in low and middle-income countries, vaccines, improved sanitation and better nutrition have saved millions of lives. In east Asia, for instance, mortality in under-fives fell by 68% between 2011 and 2023.

For older adults, the global mortality rate declined by 67% between 1950 and 2023, thanks to better screening, medication and chronic disease management.

Deaths from cardiovascular disease (the leading cause of death globally) have also improved substantially. But cardiovascular disease and other non-communicable diseases (such as cancer and diabetes) still account for nearly two-thirds of all deaths ariund the world.

For young people aged 15-24, the risk profile was different. For them, the main causes of death were primarily preventable ones.

In North America, deaths among people aged 20 to 39 rose by as much as 50% in the past decade – largely due to suicide, drug overdose and alcohol-related harms. The picture was also similar in some parts of Latin America.

But in other parts of the world, such as sub-Saharan Africa, infectious diseases (such as as tuberculosis) and unintentional injuries were the main drivers of youth mortality.

The study also highlighted stark inequalities in mortality risk for youth from marginalised, low-income or Indigenous groups. For instance, the study found that mortality in young women aged 15-29 living in sub-Saharan Africa was 61% higher than previously estimated, mostly due to maternal mortality, road injuries and meningitis.

However, these groups remain systematically underrepresented in global health datasets. The study found that more than 80% of countries lacked nationally representative data across key health domains, including mental health and child health. This meant most of the data was drawn from high-income regions.

Latin Americans, for example, make up over 8% of the global population but represent less than 1% of some global reference datasets. Such a systemic lack of representation from these groups renders their health needs invisible – including the health needs of those affecting the young.

Emerging trends

Today’s young people face unprecedented economic insecurity, social volatility, violence and pressures from social media – all of which can have an extraordinary toll on both mental health and wellbeing.

Mental health challenges underlie many of the leading causes of adolescent death reported in the study. It’s clear from this and other studies that youth mental health urgently needs to be addressed.

For instance, research from Spain which looked at over 2 million adolescent hospitalisations between 2000 and 2021, found admissions for mental health conditions more than doubled – surging especially after the COVID-19 pandemic.

For teenage boys, substance use, ADHD and psychosis were the most common causes of hospitalisation. For girls, eating disorders, anxiety and depression were more prevalent.

A related study found admissions for adolescent anorexia nervosa rose by almost 90% after 2020 – with cases overwhelmingly concentrated in girls aged 13-17.

Health survey data from 2023 also showed that half of US young adults aged 18-24 reported experiencing symptoms of anxiety or depression. Additionally, a separate US survey also found that more than one-third of 18-24-year-olds reported they’d recently thought about self-harm or suicide.

Other factors which may also have contributed to high youth mortality rates may include a historical lack of preparedness by health systems in focusing on adolescent health issues, as well as a lack of interventions aimed at reducing the actual leading causes of youth death (such as road safety, violence prevention and meaningful mental health care).

The response to youth mortality cannot be medical alone as the leading causes of death in this age group require interventions that sit outside healthcare and require coordination across sectors.

Data systems must also change. Youth from low-income countries, Indigenous people and marginalised groups are underrepresented in research. This means we don’t fully understand the needs of these groups and the problems they face – making it difficult to plan and implement effective interventions.

Youth health must be re-framed as an equity issue, as well. The current model treats young people as responsible for their own poor outcomes, when research shows that, overwhelmingly, these issues can be caused by conditions that young people do not control: poverty, exposure to violence, unsafe road environments, inadequate mental health services and lack of economic opportunity.

These deaths are preventable. We cannot celebrate global health gains when youth mortality is stagnant – and even worsening in many parts of the world. Preventing adolescent and young adult deaths is the next frontier for a fairer, healthier future.

How ‘conflict-free’ minerals are used in the waging of modern wars

Source: The Conversation – UK – By Mark Griffiths, Reader in Political Geography, Newcastle University

Minerals such as cobalt, copper, lithium, tantalum, tin and tungsten, which are all abundant in central Africa, are essential to the comforts of everyday life. Our phones, laptops and electric vehicles would not function without them.

These minerals are also tied intimately with conflict. For decades, military and paramilitary violence in the Democratic Republic of Congo (DRC) and on its borders – particularly with Rwanda – has been shaped and financed by control over some of these sought-after commodities.

Many of these minerals, including those that have supposedly been sourced responsibly, are linked to violence at the other end of the supply chain too. As we found in our recently published research, minerals sourced in central Africa play a crucial role in the waging of modern wars.

Extensive campaigning and lobbying over the past two decades has focused on the idea of “conflict-free minerals” as a way to address links between extraction and armed conflict in mining regions.

This has resulted in a suite of legislation in the EU and US obliging tech manufacturers that use minerals from the DRC and surrounding countries to submit so-called “conflict minerals reports” to national authorities.

In the US, for example, tech firms file what is known as a “specialized disclosure form” to the Securities and Exchange Commission detailing all sources of four key minerals commonly associated with conflict in Africa: tantalum, tin, tungsten and gold.

The form requires a declaration that trade is compliant with the due diligence guidelines set by the OECD on responsible supply chains in the DRC and neighbouring states. This guidance has, in turn, given rise to an industry of regulators that seeks to ensure minerals connected to conflict do not enter supply chains.

Tech companies worldwide – big and small – now comply with conflict minerals policies. The fact that these firms can be held under a critical spotlight, and that attention is falling on how bloody wars are connected to consumer products, is a positive development. But there are many flaws to this system of accountability.

One issue is the difficulty in proving that mineral supply is truly conflict free. Many of the “conflict-free” minerals sold through Rwanda, for instance, are very likely to have at least some connection to war.

In the early 2000s, when Rwandan forces were involved in armed conflict in the DRC, the UN estimated that the Rwandan army controlled between 60% and 70% of all the coltan (tantalum ore) produced there. It is widely accepted that Rwandan influence has persisted in the DRC since.

Another issue is that, under conflict-free mineral legislation, “conflict” is associated with minerals only at source. There is no oversight on how minerals are connected to conflict at the other end of supply chains in modern weapons of war.

Conflict minerals

Weapons are no longer fashioned only with lead, iron and brass. They now depend on a range of advanced technologies: lithium batteries, cobalt cathodes, tantalum resistors, nickel capacitors, tin semiconductors, tungsten electrodes and so forth.

In fact, everything advanced militaries do nowadays – whether it involves a fighter jet, drone, guided bomb, smart bullet, night vision or remote sensing – utilises these components.

As we outline in our study, conflict-free minerals are essential to the waging of modern wars. We traced the movement of ores from the DRC into Rwanda, from where they are then sold to some of the world’s largest weapons makers as “conflict-free” minerals.

A coterie of defence contractors source minerals via this route. These minerals, as our previous research shows, are used as “volumetrically minor yet functionally essential” ingredients of the products these firms sell to militaries worldwide.

To draw focus on two “conflict-free” minerals traded through Rwanda, tin and tantalum are vital to the function of a wide range of military wares. According to the US defence department, tin is present in “nearly all military hardware”.

It is crucial in compound forms to defrost screens at high altitudes and to deflect radio waves to enhance stealth. Tin is also used to power the Joint Direct Attack Munition guidance kits that improve the accuracy of bombs.

Tantalum-based semiconductors comprise the basic circuitry of drones. And among other things, tantalum is the active adsorbent material in the infrared camera tubes that make night vision possible. High-tech wars cannot be fought without these minerals, which are traded under conflict-free mineral legislation.

Researchers have long suspected that minerals can never be conflict free at source. But our findings now turn attention to the other end of the supply chain. If it is to have any purchase at all, the idea of “conflict-free” minerals must be entirely refigured.

Virtually all commentary by journalists, lawyers and scholars focuses narrowly on consumer technologies, with the injustices faced by mining communities in central Africa contrasted with phones and electric vehicles. The source of minerals is the sole focus of ethical scrutiny.

This is an important aspect of minerals supply chains. But there is a growing prominence of other tech companies, in the form of modern weapons manufacturers, whose customers are not the global masses but the militaries of the world’s most belligerent states.

Companies like Elbit Systems – which did not respond to The Conversation’s request for comment – present themselves as complying with ethical standards.

In its 2020 conflict minerals report, Elbit declared a corporate stance against “human rights abuses and atrocities”. It also expressed a commitment “to sourcing materials from companies that share our values with respect to human rights, ethics and environmental responsibility”.

Yet, as our research shows, some companies are sourcing minerals from one war zone and then making profit from another. It should be recalled that Elbit, for example, supplies “hundreds of products” to Israel’s defence ministry.

There needs to be more scrutiny on the use of minerals “downstream” to stem the flow of the raw materials that propel wars in Gaza and beyond.

Sam Fender wins Mercury prize: ‘Geordie Springsteen’ is voice of a UK ravaged by industrial decline

Source: The Conversation – UK – By Mike Jones, Course Director MA (Music Industries), University of Liverpool

The Mercury prize almost always produces surprises – among them, Gomez not The Verve in 1998, and English Teacher not Charlie XCX in 2024 – but perhaps the biggest surprise is that the prize has survived for so many years. That it has been won this year by Sam Fender in his native Newcastle speaks very much of the time that has passed in those 34 years.

Conceived as a kind of credible alternative to the Brit Awards – a prize for those beyond the razzamatazz of mainstream pop music – the (then) Mercury Music prize was introduced in 1992.

This was the year of a general election which, while won by the Conservative party, did not see the re-election of Margaret Thatcher. But Thatcher’s work had been done: the introduction of neoliberal policies which ravaged many UK industries and the regions in which they were located.

Fender can be understood as a voice of that ravaged Britain. He was born two years after John Major’s election victory, and grew up in a disintegrating family in a disintegrating former industrial region. He survived the chaos and has written about that collective suffering with great skill and passion over three albums.

It is telling, too, that the (renamed) Mercury Prize lost its corporate sponsorship along the way. Being publicly allied with music is no longer the marketing “must have” it once was. This year’s award event was paid for jointly by Newcastle City Council and the regional authority.

As Britain attempts to cope with the evaporation of major industries and the suffering that permanent loss of employment infrastructure induces, many UK regions now foreground the creative abilities of their residents as a reason to invest in their particular area. Demand for music, and for the creativity it carries and expresses, has become a key feature of social and economic as well as cultural life.

This begs the question: what is it that creative people actually contribute? The 2025 Mercury prize shortlist gives us some clues, especially if we look at three of the nominees who missed out on the prize: Pulp, Wolf Alice and Martin Carthy. Both Pulp and Wolf Alice are previous winners (1996 and 2018 respectively), but Carthy has won very few awards over the 84 years of his life.

“Notable” musicians tend to be of their time. This is partly because their choice of instruments and combinations of keys, notes and tempos resonate with the moments they and their audiences are living through. But there is more to being a musician than this.

Real, affecting performance draws on and mobilises symbolic information far beyond musical soundmaking – even though that demands skill and ability. Fender, for example, is unequivocally a Geordie, even as he fits the mould of a kind of Bruce Springsteen for his times.

Both Pulp and Wolf Alice are challenging to discuss. Where Jarvis Cocker is concerned, the word “uncompromising” comes to mind, but what does that mean? Here is someone who is unique – yet what his vision of the world is, is never quite apparent. Cocker is “about something”, and he is about it so strongly that people stand back and admire him for it.

Wolf Alice are something different: a successful rock band in a time when rock bands have gone into decline. It is almost the band’s own self-awareness that, somehow, “they shouldn’t be” that gives them their energy – mining rock’s extensive back catalogue to support essentially introspective lyrics about (mainly singer Ellie Rowsell) self-adjusting to the demands of an evermore turbulent world.

In this, there are shades of Cocker. And with Fender singing about negotiating this turbulence too (only with a more explicit set of references to a world beyond his interior), so the core strengths of contemporary music begin to emerge.

Popular musicians go on providing a soundtrack for our lives because they express themselves through the idioms of the moment. If we take Fender’s previous album, Seventeen Going Under, as a point of reference, every aspect of the recording and its video speaks to his growing up in the northeast of England and his continuing loyalty to the place.

His moving acceptance speech and rapport with the audience were evidence of this. His performance of People Watching was almost pure Bruce Springsteen – mainstream rock inflected and defined by a hometown sensibility.

Which brings us to Martin Carthy. It is impossible to capture Carthy’s significance in words, because his voice cannot be heard on the page – and it is so powerfully distinctive that it needs to be heard.

Carthy was the soul of English folk music in the 1960s and ’70s. His brand of folk music speaks to a resilience through suffering – the suffering of pre-industrial society articulated through song. Now, Fender is speaking to the suffering of post-industrial society. They both should have won.

The fungi living in the body play an important role in health – here’s what you should know about the ‘mycobiome’

Source: The Conversation – UK – By Rebecca A. Drummond, Professor, Immunology and Immunotherapy, University of Birmingham

The “gut microbiome” has become a popular health term in recent years. It’s easy to see why, with an abundance of research showing how important the trillions of microbes living in our gut are for health.

But what many people might not realise is that the microbiome doesn’t only contain bacteria. It also contains other types of microbes – including fungi. The fungal component of the microbiome is called the “mycobiome”.

Although the mycobiome has been less well studied than its bacterial counterpart, recent research shows it’s sensitive to diet and may affect our health, too.

The best studied mycobiome is the one in our intestines. It’s composed of many fungal species. The most common fungal species found there, particularly in the Western world, belong to the Candida family.

Candida are a type of yeast. For most of us, the Candida population in our mycobiome is kept in check by our immune system and our gut bacteria. But changes to either of these can cause populations of Candida to expand in the mycobiome. This can be a problem, because Candida may cause life-threatening infections in people with damaged immune systems.

For example, research found that hospital patients who are given antibiotics are more likely to develop Candida infections.

This is partly explained by the effect of antibiotics, which kill off certain species of gut bacteria that compete with Candida for space and resources within the intestine. Antibiotics have also been found to directly alter our immune cells and how they fight fungal infections.

Another study, which analysed the mycobiome of cancer patients, found that those who developed serious Candida infections had an overgrowth of the fungus in their mycobiome just before the infection started. Combined with the damaging effects of chemotherapy on the immune system, this made it harder for patients to fight off the infection.

Disruption in the mycobiome’s Candida balance has also been linked to several other diseases. For instance, Candida levels are high in patients who are critically ill. This suggests that too much Candida in our guts is a sign of poor health.

Changes in the fungal mycobiome have also been linked to several gut diseases, including inflammatory bowel disease. Research on Crohn’s disease has also shown that patients have an overgrowth of Candida. These fungi also produce toxins that irritate the gut lining, which could potentially explain some of the symptoms Crohn’s patients experience.

High levels of Candida in the gut can activate immune cells as well, making them more inflammatory. This has been seen in patients with severe COVID-19.

Mycobiomes in the body

The mycobiome isn’t only found in our gut.

We also have a skin mycobiome. In fact, the skin between our toes contains a more diverse number of fungal species than any other skin mycobiome.

The skin mycobiome is mostly dominated by a fungus called Malassezia. This yeast has adapted to grow on the skin’s surface.

Malassezia can activate the immune cells that reside between the skin’s layers. This may lead to inflammation linked to skin disorders, such as psoriasis and eczema.

Candida auris is also a cause for concern. This fungus is resistant to many antifungal drugs, which is why it can be a problem if it grows on the skin’s surface. In a hospital or emergency room, this could be dangerous – particularly to patients who have immune system problems.

Women also have a mycobiome within the vagina. Its balance with the bacterial communities living there can be a big determinant for vaginal health.

One of the most common fungal infections globally is vaginal candidiasis (thrush). It can cause symptoms such as intense itching, pain and swelling. Many adult women will experience at least one thrush infection in their lifetime.

The source of thrush is another fungus from the Candida family: Candida albicans. This is a common member of the vaginal mycobiome.

The vagina’s microbiome is normally dominated by the bacteria Lactobacillus which help keep Candida populations in check. But if the balance between bacteria and fungi gets disrupted (for example, by antibiotics), the fungus can overgrow or produce inflammatory molecules within the vagina. This inflammatory response is responsible for common thrush symptoms such as redness and itching.

Probiotics may help to restore the balance between fungi and bacteria to prevent vaginal yeast infections – although this has had limited success so far. Some new treatments that target inflammation-causing fungal molecules have shown promise in animal models and in small numbers of women.

There’s good evidence to suggest we might also have a mycobiome in the lungs and in breastmilk.

Controversially, some have even suggested that we may have small numbers of fungal cells in the brain – and these fungal cells may be linked with neurodegenerative disorders such as Parkinsons and Alzheimer’s.

Autopsy studies have found evidence of fungi in the brains of people who died from brain disorders – but this doesn’t prove the fungi caused their illness or that it was there during their life.

Experimental studies in mice have also shown that small numbers of fungal cells can survive in the brain for long periods of time – and the presence of these fungal cells was linked with reduced memory function.

Experiments in flies have also shown fungi may travel to the brain and affect function. This is the best evidence we currently have showing small numbers of fungi may get into the brain and survive long-term.

Whether this occurs in people, and if this would be considered a true mycobiome, remains to be proven.

There’s still much we don’t know about the mycobiome. But with continued research in this area we may soon better understand the mycobiome’s importance in our health and how we can nurture and care for it.

Surge in global youth mortality fuelled by mental illness, drugs, violence and other preventable causes

Source: The Conversation – UK – By Manuel Corpas, Lecturer in Genomics, University of Westminster

In some regions, youth mortality has actually risen in the past decade. KieferPix/ Shutterstock

Global mortality continues to fall. Life expectancy has improved to unprecedented levels and deaths in young children have plummeted. Yet for adolescents and young adults, especially those aged 15 to 24, little progress has been made according to data from the latest Global Burden of Disease study. In parts of North America and eastern Europe, mortality in those aged 15-24 has actually risen in the past decade.

This latest study also showed the main causes of death among young people aren’t disease or poor health. The main causes were shown to be injury, violence, suicide, road traffic accidents and substance abuse.

This shows us that health systems worldwide are still ill-equipped to prevent or intervene effectively in social and structural causes of youth mortality.

The Global Burden of Disease study is one of the largest studies on the picture of health, disease and mortality worldwide. The study analysed more than 310,000 data sources collected between 1950 and 2023 from 204 countries. Using death registries, censuses and household surveys, the research team estimated age-specific mortality trends across the lifespan.

The overall picture is one of uneven progress.

For children, especially in low and middle-income countries, vaccines, improved sanitation and better nutrition have saved millions of lives. In east Asia, for instance, mortality in under-fives fell by 68% between 2011 and 2023.

For older adults, the global mortality rate declined by 67% between 1950 and 2023, thanks to better screening, medication and chronic disease management.

Deaths from cardiovascular disease (the leading cause of death globally) have also improved substantially. But cardiovascular disease and other non-communicable diseases (such as cancer and diabetes) still account for nearly two-thirds of all deaths ariund the world.

For young people aged 15-24, the risk profile was different. For them, the main causes of death were primarily preventable ones.

In North America, deaths among people aged 20 to 39 rose by as much as 50% in the past decade – largely due to suicide, drug overdose and alcohol-related harms. The picture was also similar in some parts of Latin America.

But in other parts of the world, such as sub-Saharan Africa, infectious diseases (such as as tuberculosis) and unintentional injuries were the main drivers of youth mortality.

The study also highlighted stark inequalities in mortality risk for youth from marginalised, low-income or Indigenous groups. For instance, the study found that mortality in young women aged 15-29 living in sub-Saharan Africa was 61% higher than previously estimated, mostly due to maternal mortality, road injuries and meningitis.

However, these groups remain systematically underrepresented in global health datasets. The study found that more than 80% of countries lacked nationally representative data across key health domains, including mental health and child health. This meant most of the data was drawn from high-income regions.

Latin Americans, for example, make up over 8% of the global population but represent less than 1% of some global reference datasets. Such a systemic lack of representation from these groups renders their health needs invisible – including the health needs of those affecting the young.

Emerging trends

Today’s young people face unprecedented economic insecurity, social volatility, violence and pressures from social media – all of which can have an extraordinary toll on both mental health and wellbeing.

Mental health challenges underlie many of the leading causes of adolescent death reported in the study. It’s clear from this and other studies that youth mental health urgently needs to be addressed.

For instance, research from Spain which looked at over 2 million adolescent hospitalisations between 2000 and 2021, found admissions for mental health conditions more than doubled – surging especially after the COVID-19 pandemic.

For teenage boys, substance use, ADHD and psychosis were the most common causes of hospitalisation. For girls, eating disorders, anxiety and depression were more prevalent.

A related study found admissions for adolescent anorexia nervosa rose by almost 90% after 2020 – with cases overwhelmingly concentrated in girls aged 13-17.

Health survey data from 2023 also showed that half of US young adults aged 18-24 reported experiencing symptoms of anxiety or depression. Additionally, a separate US survey also found that more than one-third of 18-24-year-olds reported they’d recently thought about self-harm or suicide.

Other factors which may also have contributed to high youth mortality rates may include a historical lack of preparedness by health systems in focusing on adolescent health issues, as well as a lack of interventions aimed at reducing the actual leading causes of youth death (such as road safety, violence prevention and meaningful mental health care).

The response to youth mortality cannot be medical alone as the leading causes of death in this age group require interventions that sit outside healthcare and require coordination across sectors.

Data systems must also change. Youth from low-income countries, Indigenous people and marginalised groups are underrepresented in research. This means we don’t fully understand the needs of these groups and the problems they face – making it difficult to plan and implement effective interventions.

Youth health must be re-framed as an equity issue, as well. The current model treats young people as responsible for their own poor outcomes, when research shows that, overwhelmingly, these issues can be caused by conditions that young people do not control: poverty, exposure to violence, unsafe road environments, inadequate mental health services and lack of economic opportunity.

These deaths are preventable. We cannot celebrate global health gains when youth mortality is stagnant – and even worsening in many parts of the world. Preventing adolescent and young adult deaths is the next frontier for a fairer, healthier future.

Our research shows COVID-19 made people appreciate street cleaners more – but it also made their lives harder

Source: The Conversation – UK – By Natasha Slutskaya, Chair Professor, Work and Organization Studies, University of Sussex

In the early days of the pandemic, “solidarity” became a buzzword. As COVID-19 appeared to directly threaten us all, the UK celebrated its key workers who were keeping the country running.

This idea ran through discussions on TV and on social media. The Clap for Our Carers movement had people gathering outside on their doorsteps, applauding, ringing bells, chanting and banging on pots and pans to signal their support.

As a result, the collective reliance on various workforces, such as carers, street cleaners, refuse collectors and supermarket workers, to name a few, became increasingly transparent. Public demonstrations of solidarity with these workers gave the initial impression that the status we attach to such work might be revalued: instead of the low status to which these jobs were assigned before, COVID-19 underlined how essential they are.

However, our research on refuse workers shows that this has not translated into a permanent reevaluation of the benefit key workers bring. On the contrary, instead of a collective shift towards real social solidarity, the pandemic has exacerbated socioeconomic divisions.

Unexpected visibility

Between the UK’s first and the second lockdowns in 2020 and again, in the period after the end of the second lockdown in 2021, we interviewed 41 council workers involved in waste management across four sites in London and south-east England. Two were sites where we had previously conducted ethnographic research among street cleaners and refuse collectors.

We wanted to investigate if, and how, the pandemic affected the way that key workers involved in waste management are recognised. We asked our interviewees to reflect on and compare their experiences of working before, during and after the lockdown. We wondered whether they had noticed any changes in their interactions with the public and how they thought these developments might affect them in the future.

We found that the pandemic gave these workers moments of unexpected visibility and recognition. Not only did this show, to their minds, increased public respect, it also gave them hope that social bonds between workers and the public might be strengthened in the long term. They saw the possibility of a novel, yet seemingly mutual acknowledgement and respect. As Keith, one of our interviewees, put it:

During the pandemic we’re part of it, yes … it’s kind of like the police, the fire brigade, the ambulance, the hospitals, it’s part of the services of a community, working to keep the community functioning, and what we do is part of that.

And yet, this experience of coming together was eroded by the unequal consequences of the pandemic for different social groups. Our participants spoke of the differences they saw in people’s ability to distance themselves from the unpleasant or potentially dangerous aspects of the pandemic.

Whereas these workers still had to go to work everyday, other people did not. Our interviewees also noted the stark gap separating those key workers who performed the riskiest jobs (nurses, carers) and those whose jobs involved little risk and could be undertaken from home.

Another interviewee, Kevin, who works as a dustcart driver said:

COVID’s still going on now, because we’re not out of it yet. But, still, they’ve just carried on as their normal day, stayed at home working, while the likes of me go out there all day. And if I don’t work, I don’t get paid.

This chimed with what Nigel, a litter picker, reported:

They’re at home, comfortable. We get nothing. No nothing. Not even ‘Oh, we’ll give you a couple of days, like a couple of days extra as your holiday so you can recover and that’, nothing.

The pandemic also made broader social divisions more tangible. Our interviewees spoke about those with privilege seeming to lack interest in knowing about the deteriorating living conditions of workers like themselves. This was despite the fact that the activities these workers were doing, like waste collection and street cleaning, were vital for societal functioning. Another litter picker, Bernie, put it plainly:

You see people, you see some people going and spending like £12, £16 a day just on food going and buying lunch, and I sit there and I think: ‘How the hell do you do it?’ Nine times out of ten I have to make lunch just buying basics, you know, like a cheap loaf of bread, cheap bit of meat – luxury is a bit of sauce. They don’t want to think about people like me.

This illustrates the oxymoron of being “visibly invisible”. During the pandemic, keyworkers’ effort became more apparent. At the same time, they sensed little desire from the wider public to consider and challenge the cultural and socioeconomic factors that were negatively affecting their lives.

Our findings chime with research on how nurses, too, experienced the pandemic, with comparable levels of scepticism with regards to positive, long-term transformations. The question is whether, as German sociologist Andreas Reckwitz has argued, we are witnessing an increasing polarisation between different groups and social classes. Our research suggests that the sense that the world can be improved and society become more progressive feels ever more remote.

This has worrying implications for societal solidarity. As inequality grows, the mutual obligations citizens might have towards one another are increasingly being eroded.

Monsters, menopause and bold women – what to see, read and visit this week

Source: The Conversation – UK – By Naomi Joseph, Arts + Culture Editor, The Conversation

Mary Shelley’s Frankenstein has long served as a parable – a warning against the hubris of playing God, the dangers of motherless creation, reckless parenthood and unchecked scientific ambition. It’s a story that continues to resonate, revealing how little human ego and error have changed over time.

In the latest adaptation from horror maestro Guillermo del Toro, the tale of a mad scientist and his unnatural creation is reimagined with his signature touch. Like Shelley’s original, the film challenges us to ask: Who is the real monster?

Del Toro layers this timeless question with visual and thematic echoes from his own canon. Fans will spot traces of Crimson Peak in the gothic set design, Cronos in the intricate costuming, and The Shape of Water in its emotional core.

This version of Frankenstein is a visual feast – lavishly constructed and meticulously researched. As our reviewer Sharon Ruston points out, it incorporates real elements from early surgical education, including the gruesome 17th-century anatomy guides known as the Evelyn Tables. It also weaves in the history of Arctic exploration; those familiar with the doomed voyages of the Terror and Erebus will recognise their spectral influence.

I strongly recommend seeing this in cinemas. The immersive sound design and Alexandre Desplat’s haunting score pull you deep into this eerie, beautiful world. And if you’re in London, don’t miss the exhibition at Selfridges, where you can get up close to the props and costumes and appreciate the craftsmanship behind the film. It pairs perfectly with a visit to the Hunterian Museum, where the real Evelyn Tables are on display.

Frankenstein is in cinemas now, and will be available to watch on Netflix from November 7.

Bold women

Virginia Woolf has a new book out. No, she hasn’t sent it from beyond the grave. And no, it’s not the product of an AI trained on her oeuvre. The Life of Violet is a newly unearthed early work by Woolf, available to read for the very first time.

This early foray into the genre of mock biography – which she would later explore more fully in Flush and Orlando – is composed of three short, fairytale-like stories chronicling the life of her close friend, Violet Dickinson.

Within these vivid, fantastical sketches, we see the early sparks of themes that would later define Woolf’s work: sharp satire of societal ills, the suffocating constraints of social norms, the joys and limits of womanhood, the quiet power of female friendship, and the deep yearning for freedom and choice.

Short, surreal and bitingly witty, these stories are a treat for new readers and a treasure for long-time Woolf fans who thought they had read it all.

Life of Violet: Three Early Stories is available at most bookshops

If you’re looking for something binge-worthy this weekend, don’t miss Riot Women, Sally Wainwright’s bold and brilliant new drama.

The series follows five menopausal women who rediscover themselves – and find their voices – through punk at a time when life is pulling them in every direction: children, ageing parents, difficult men and demanding jobs with lousy bosses.

Tonally rich and emotionally layered, Riot Women balances laugh-out-loud moments with poignant, deeply felt drama. It’s a nuanced portrait of midlife – of caregiving, exhaustion, resilience and the fierce beauty of friendship. “These are not neat storylines,” reviewer Beth Johnson writes, “they are ongoing negotiations with life.”

The show’s strength lies in Wainwright’s deft storytelling, and an exceptional cast including Joanna Scanlan, Tamsin Greig and Rosalie Craig.

Riot Women is available to watch on BBC iPlayer now

More than just art

I first encountered the work of Lee Miller last year at the Heide Museum of Modern Art in Melbourne. I was instantly captivated. Here was a woman far ahead of her time: model, fashion photographer, surrealist artist and one of the few female war correspondents accredited by the US Army during the second world war.

Her photographs are fearless, witty and wide-ranging – from surreal shots of Egypt’s landscapes to scenes of wartime London. As fine art expert Lynn Hilditch notes, the documentation of people in the liberated Holocaust camps and refugees in the aftermath stand out as both harrowing and deeply human.

Now, Miller’s work takes centre stage in the first major UK retrospective at Tate Britain. Featuring more than 250 vintage and modern prints, film and original publications (many never before shown), the exhibition is a long-overdue celebration of her legacy.

Lee Miller is at Tate Britain in London till 15 February 2026.

If you’re after an autumn city break, Amsterdam makes for a perfect long weekend – and right now, the Van Gogh Museum is offering something truly special.

On show is a remarkable exhibition bringing together 14 portraits of the family of Joseph Roulin – the postman who became one of Van Gogh’s closest friends during his time in Arles, in the south of France. Van Gogh painted Roulin’s wife Augustine and their three children with affection and intensity, transforming ordinary subjects into something universal.

As Frances Fowle writes, Van Gogh wasn’t just painting individuals – he was capturing archetypes. In these enigmatic portraits, we see not just a family but timeless figures: a comforting mother, a boy desperate to be a man, an innocent baby.

Van Gogh and the Roulins – Together Again At Last is at the Van Gogh Museum in Amsterdam until January 11 2026.
