A finales del siglo XX, España podía reconocer en el mundo con claridad “su” música, desde el melódico Julio Iglesias, el pop luminoso de Mecano o la fuerza de Héroes del Silencio a la sensibilidad con toques aflamencados de Alejandro Sanz o el indie que marcó a una generación.

Sin embargo, en 2025 la pregunta ya no es qué define la identidad de la música española, sino si ese concepto sigue teniendo sentido dentro de un ecosistema en el que el español se ha vuelto global, híbrido y profundamente interconectado.

Esta es una de las reflexiones del nuevo informe del Observatorio Nebrija del Español, donde se detecta cómo España ha pasado de exportar voces a formar parte de una red transnacional en la que los acentos se cruzan y los ritmos se comparten.

De la exportación de artistas a la importación de éxitos

España ha actuado como uno de los grandes emisores de música en español. Durante los años 80 y 90 se produjo la profesionalización de la industria española, marcada por la concentración del mercado en manos de compañías multinacionales. A diferencia de lo que sucedía en otras naciones europeas, la transformación fue vertiginosa.

Así, si en 1980 siete sellos globales controlaban un 52 % del mercado, ya en 1985 solo cinco discográficas aglutinaban el 87 %. Este crecimiento se sumó a la confluencia de una explosión creativa y al apoyo de la radio, algunos programas de televisión y las revistas musicales. También las nuevas tecnologías de consumo físico musical –como el CD– interpretaron su papel en la expansión internacional de los grandes referentes del pop español.

Pero a partir de los años 2000, esa fórmula de éxito comenzó a cambiar, primero de una manera tímida y luego de forma estructural. Así, pasamos de lo físico a lo digital impulsados por el auge de una piratería que sumió a la industria en una crisis de ventas que acabó afectando a todo el sistema.

En ese punto de inflexión, en 2005, una colaboración entre la colombiana Shakira y el español Alejandro Sanz reveló que el idioma era un vector más poderoso que cualquier identidad nacional. La canción “La tortura” anticipó la explosión de un pop latino-global cuya arquitectura ya no dependía del país de origen del artista sino de su conexión con una comunidad lingüística transcontinental.

Desde entonces, España comenzó a importar sonidos, estilos, productores y narrativas que provenían de América Latina. Los datos son reveladores: cuando analizamos el consumo musical en España de las últimas dos décadas, siete de cada diez canciones se cantan en español. De hecho, el 94 % de la música que consume esta audiencia YouTube se canta en español, al igual que el 87 % de lo que escuchan en Spotify. Pero solo una cuarta parte de esas canciones son de intérpretes originarios de España. Es decir, el español que está dominando las listas de éxitos posee muchos acentos.

No obstante, esto no indica una pérdida de relevancia cultural de los artistas españoles, sino un desplazamiento del eje. Podría decirse que la identidad musical está dejando de ser local para convertirse en lingüística y relacional. Así el Spanish sound ya no se entiende como una estética propia y diferenciada de un país sino como parte de un espacio común compartido, el “orgullo latino” que puede surgir desde Medellín, San Juan o Buenos Aires a Ciudad de México, Miami, Cuenca, Terrassa o las islas Canarias.

La identidad musical por contribución

El auge de la música en español en el escenario global no surge de la nada, ni es simplemente algo que el viento del mercado ha traído consigo. Es más bien el punto de encuentro de corrientes históricas y tecnologías que, en los últimos 20 años, han ido reconfigurando las rutas por las que viaja la cultura en un planeta interconectado.

En los años 90 la música en español funcionaba como un mercado fragmentado, jerarquizado, con flujos unidireccionales (en España ligado al pop y en Estados Unidos, al Spanglish). Hoy, sin embargo, actúa como una comunidad digital, fluida, global y dopada por los algoritmos. Las plataformas que han borrado fronteras también han revelado un dato fundamental: el español es uno de los idiomas más escuchados del mundo en las listas de éxitos.

En este contexto, los artistas españoles navegan entre la idea de preservar ciertas raíces culturales mientras adoptan sonidos y estéticas que conectan con audiencias globales. Se observa un cambio generacional de artistas superventas del pop español como Estopa, Pablo Alborán o Dani Martín para pasar a Juan Magán, Rosalía, Quevedo y RVFV, referentes de propuestas que se integran en un lenguaje musical más amplio.

Las mujeres facturan

Otro vector clave que impulsa la música en español es el femenino.

La presencia de Karol G y Rosalía en las listas de éxitos globales, junto a una figura transgeneracional como Shakira –quien constituye un caso singular de reinvención sostenida dentro de la industria latina–, permite observar un cambio de ciclo en la música popular contemporánea.

A ellas se suman intérpretes españolas con fuerte impronta internacional. Así, y según Chartmetric, para Aitana, Bad Gyal y Ana Mena México es su mercado secundario, mientras que Argentina lo es para Lola Índigo. Por tanto, la relevancia de estas artistas no puede entenderse ya como regional o local, sino como parte de un ecosistema cultural crecientemente interconectado que les permite disputar espacios simbólicos históricamente masculinizados.

En uno de sus conciertos en Madrid en 2024, Karol G subió al escenario a Amaia Montero, entonces excantante de La oreja de Van Gogh, en un momento que ejemplificaba la unión de dos generaciones musicales en español.

Su visibilidad y su forma de reinterpretar el género, lejos de ser un fenómeno aislado marca un hito en la historia de la representación femenina. Este empoderamiento femenino y latino que encarnan abre puertas para nuevas generaciones y legitima una diversidad de expresiones que amplían los márgenes en la cultura popular contemporánea desde el español.

Al final, la música en este idioma no es un tema de banderas, sino voces que conquistan. Lo que importa no es el origen del sonido, sino la amplitud de su eco.

Wikipedia cumple 25 años: ¿cómo la enciclopedia que la academia rechazaba se ha convertido en un bien público digital?

Fundada el 15 de enero de 2001, Wikipedia cumple en estos días 25 años. Tras 25 años de historia, ha pasado de ser cuestionada por la academia a ser reconocida como un bien público global. Con más de 65 millones de artículos en su edición en inglés y presencia en más de 300 idiomas, hoy por hoy es reconocida como la mayor fuente de conocimiento colaborativo accesible y gratuito.

Su crecimiento ha logrado romper barreras geográficas y lingüísticas. Sin embargo, mantiene una lucha constante por ser más inclusiva. A través de iniciativas para reducir la brecha de género y visibilizar conocimientos del Sur Global, Wikipedia busca que el saber sea representativo.

Del estigma a la fiabilidad

Durante años, Wikipedia fue el enemigo en escuelas y bibliotecas. Se consideraba poco fiable porque cualquiera podía editarla, e incluso era común prohibir su uso y cita en los trabajos universitarios.

Las preocupaciones y discusiones sobre la fiabilidad de sus contenidos han sido objeto de constantes debates académicos y estudios críticos. Desafíos como los sesgos de género, las brechas geográficas, la calidad desigual entre idiomas y el vandalismo persistente son realidades vigentes que impactan fuertemente la credibilidad de Wikipedia.

Ante ello, la comunidad de wikipedistas ha afinado sus políticas y prácticas. Asimismo, el desarrollo de herramientas de verificación propias y externas ha mejorado la percepción sobre la enciclopedia. Aun así, la fiabilidad no es un estado fijo, sino un proceso en construcción permanente.

En la actualidad, tanto el ámbito de la educación como el mundo de la ciencia ven a Wikipedia como una aliada. Docentes e investigadores ayudan a mejorar los artículos con sus conocimientos. Sus aportaciones permiten que la sociedad acceda a información validada y de calidad.

La desconfianza inicial ha dado paso a alianzas y a una colaboración global. Universidades, instituciones culturales y ciudadanos construyen y mejoran juntos Wikipedia. El resultado es el acceso a un conocimiento humano, abierto, libre y gratuito.

Un bien público digital para el mundo

Wikipedia es una infraestructura esencial para el acceso al conocimiento en internet. Su historia como fuente de acceso libre y de código abierto es un ejemplo único del potencial de las tecnologías abiertas.

Su modelo colaborativo le ha permitido construir y contribuir a un acceso al conocimiento más equitativo. Su valor como proyecto fue reconocido en 2025 por la Digital Public Goods Alliance (DPGA). Esta iniciativa, respaldada por la ONU, gestiona un registro de bienes digitales que resultan de interés público: software de código abierto, modelos de IA, estándares y contenidos digitales.

El reconocimiento de Wikipedia como bien público digital certifica que cumple con estándares de software abierto, contenido libre y protección de la privacidad. Esta distinción también destaca su contribución a los Objetivos de Desarrollo Sostenible.

La misión de la Fundación Wikimedia, la organización responsable de sustentar el proyecto Wikipedia, también se beneficia de esta acreditación y de su consecuente valoración.

Al ser un recurso gratuito, accesible y libre de barreras comerciales, Wikipedia contribuye a reducir la brecha digital. Su modelo democratiza el acceso a la información a nivel global y garantiza que el conocimiento sea un recurso compartido y protegido para las generaciones futuras.

Sin embargo, en la actualidad este modelo enfrenta un desafío existencial: el auge de la Inteligencia Artificial generativa. Wikipedia es una de las fuentes principales para entrenar los grandes modelos de lenguaje. Este fenómeno obliga al proyecto a repensar su sostenibilidad y a defender su valor como fuente primaria de información generada y verificada por personas. Frente la automatización, Wikipedia reivindica el factor humano como el único capaz de producir conocimiento enciclopédico confiable, algo que la tecnología por sí sola no puede reemplazar.

Proteger Wikipedia frente al futuro digital

A pesar de su consolidación como infraestructura libre y gratuita, la viabilidad de Wikipedia como modelo y plataforma abierta enfrenta, junto con otros proyectos de conocimiento libre, desafíos y amenazas globales. Estas presiones han venido generando temores sobre la fragmentación de internet y la posible vulneración de los derechos humanos en el entorno digital.

En este escenario, la gobernanza de internet es una prioridad. Según los principios impulsados por la UNESCO, es vital que internet se mantenga como un recurso basado en los derechos humanos, abierto y accesible para todos.

Sin embargo, las políticas diseñadas para regular los entornos digitales a menudo no consideran la naturaleza única de los bienes públicos digitales. Con ello se pone en riesgo el principio de cooperación global, necesario para un futuro inclusivo en este ámbito.

Frente a estos riesgos, y en el marco del Pacto Digital Mundial de las Naciones Unidas, la Fundación Wikimedia ha liderado una carta abierta instando a los Estados miembros de las Naciones Unidas a proteger los proyectos de conocimiento libre y colaborativo.

Este llamado es un recordatorio de que la sostenibilidad de Wikipedia y otros proyectos de interés público no depende solo de su comunidad, sino de un marco normativo global que reconozca que el acceso al saber es un derecho humano fundamental y un pilar del desarrollo de la sociedad.

25 años de conocimiento humano

Celebrar el 25 aniversario de Wikipedia es una muestra y una defensa de que el conocimiento no es un producto estático, sino un proceso social vivo.

El lema “El conocimiento es humano” nos recuerda que detrás de cada artículo hay una comunidad global que defiende la verdad y la apertura. Lo que comenzó como un experimento audaz es hoy un patrimonio compartido. Proteger su legado no representa solo un acto de preservación tecnológica: implica garantizar que, en el futuro digital, el conocimiento sea un derecho, libre, accesible, de todos y para todos.

¿Se quedarán sin nieve los Pirineos por culpa del cambio climático?

Source: The Conversation – (in Spanish) – By Josep Bonsoms, Postdoctoral researcher and professor, Universitat de Barcelona

La nieve es uno de los elementos más característicos de las montañas y del invierno en gran parte del mundo. Más allá de su valor paisajístico, esta desempeña un papel clave en el funcionamiento de los ecosistemas de montaña y en múltiples actividades socioeconómicas.

Sin embargo, la nieve es también un componente del sistema climático especialmente sensible al calentamiento global. En las últimas décadas, su cantidad, duración y comportamiento han mostrado cambios significativos.

No nieva igual todos los inviernos

La nieve presenta una marcada variabilidad temporal y espacial. En las montañas de la península ibérica, los inviernos pueden alternar entre años con abundantes nevadas y otros casi sin nieve.

Esta variabilidad no es homogénea. Las cotas bajas y sectores como el Pirineo oriental son más irregulares debido a su posición frente a los flujos atlánticos, mientras que cordilleras occidentales y septentrionales actúan como barrera, captando la mayor parte de la humedad y dejando condiciones más secas hacia el este. Este fenómeno, conocido como sombra pluviométrica, también es observable en otras montañas españolas como Sierra Nevada.

A escala local, además, el relieve y el viento influyen también en la acumulación de nieve. En conjunto, estos factores hacen que las tendencias espacio-temporales de la nieve muestren una elevada heterogeneidad.

¿Hay menos nieve en el hemisferio norte?

A escala del hemisferio norte, la cobertura de nieve ha disminuido de forma acelerada desde la década de 1980. Este descenso se atribuye principalmente al aumento de la temperatura vinculado al cambio climático de origen antrópico. Este fenómeno ha dado lugar a lo que se conoce como sequía nival hidrológica, es decir, cuando la acumulación de nieve es insuficiente o la fusión es demasiado rápida y se genera un déficit respecto a un periodo histórico concreto.

Aun así, durante la estación fría, en cotas elevadas y en latitudes altas, la acumulación de nieve depende más de la precipitación que de la temperatura. En las latitudes medias de la cuenca del Mediterráneo, la precipitación presenta una elevada variabilidad anual y decadal, sin que se observen tendencias claras a lo largo del periodo histórico.

En los Pirineos, en cotas elevadas (>2 000 m), donde las temperaturas se mantienen bajo cero, las tendencias recientes (2000-2020) son neutras o ligeramente positivas. Sin embargo, en periodos más largos (1958–2017) se observa una disminución generalizada del número de días con nieve en el suelo y del espesor medio.

Además, en este sistema montañoso se detecta una fusión cada vez más temprana en la temporada y más intensa, asociada a un aumento de la energía disponible para derretir la nieve. Este fenómeno se ha relacionado con una mayor frecuencia de situaciones anticiclónicas durante la primavera. Estos periodos de estabilidad atmosférica favorecen la entrada de masas de aire templado, incrementan la radiación y el calor sensible, y aceleran la fusión. Estas situaciones atmosféricas se producen actualmente con temperaturas más elevadas debido al calentamiento global.

¿Qué pasará en el futuro?

Los estudios basados en simulaciones climáticas coinciden en proyectar una disminución de la nieve en el hemisferio norte, independientemente del modelo climático utilizado y del escenario de emisiones de gases de efecto invernadero considerado, tanto moderado como alto.

En los Pirineos, las proyecciones apuntan a una reducción generalizada de la nieve, especialmente en las cotas bajas, donde pequeños aumentos de temperatura determinan si la precipitación cae en forma de nieve o de lluvia.

Aun así, la nieve no desaparecerá de esta cadena montañosa, ni siquiera a finales de siglo. En concreto, las proyecciones para finales del siglo XXI (2080–2100) anticipan reducciones de la precipitación nival que oscilan entre el −9 % en un escenario de emisiones moderadas (entre 2 500 y 3 000 m) y el −29 % en un escenario de altas emisiones (entre 1 000 y 1 500 m), en comparación con el clima histórico (periodo 1960–2006).

Estos cambios afectan también la duración de la temporada de nieve, la rapidez de la fusión y los picos de escorrentía, es decir, el agua que circula por la superficie. Un aumento de 1 °C puede reducir hasta un 30 % la nieve estacional a 1 500 m.

Además, estudios recientes indican que el aumento de la temperatura debido al cambio climático contribuye a una mayor evaporación y a una mayor cantidad de humedad disponible en la atmósfera, lo que puede dar lugar a un incremento de episodios extremos de precipitación en forma de nieve, como la borrasca Filomena de 2021, siempre que la temperatura se sitúe por debajo del punto de fusión.

A mayor calentamiento global, ¿menos nieve en las montañas?


Implicaciones para el clima y los ecosistemas

La nieve es un factor clave en las zonas de montaña. Actúa como un regulador hidrológico natural: almacena agua durante los meses fríos y la libera de forma progresiva en primavera y verano. Su disminución altera los picos de escorrentía, afecta a la disponibilidad de recursos hídricos y condiciona la producción hidroeléctrica.

La nieve desempeña un papel fundamental en el clima debido a su alto albedo, ya que refleja gran parte de la radiación solar. La pérdida de cobertura nival incrementa la absorción de energía en la superficie, generando retroalimentaciones que aumentan la temperatura.

Los cambios en la nieve influyen también en los ecosistemas de montaña, en la fenología de la vegetación –en sus ciclos biológicos– y en la evolución de los glaciares, que dependen de una cubierta nival persistente para retrasar la exposición del hielo durante el verano. Además, el aumento de episodios de lluvia sobre nieve, favorecidos por temperaturas más elevadas, puede desencadenar crecidas rápidas e inundaciones, como la ocurrida en el municipio de Vielha (Lérida) en 2013, con elevados costes económicos.

The UK’s offshore wind auction broke records, but its clean power target remains unrealistic

Source: The Conversation – UK – By Thomas York, Postgraduate Researcher in Human Geography, University of Leicester

The UK government has just announced the results of its biggest-ever auction for new offshore wind projects. By doubling the budget at the eleventh hour, it managed to award contracts for a massive 8.4 gigawatts of new capacity. Energy secretary Ed Miliband described it as “a monumental step towards clean power by 2030”.

But despite the headline success, this outcome actually makes the government’s own clean power targets harder – not easier – to meet. While the auction successfully awarded contracts, it does nothing to address the bottlenecks that mean these projects won’t start producing electricity for many years.

German company RWE dominated the auction. It has been awarded contracts for 6.9GW of capacity, securing revenue for its Dogger Bank South, Norfolk Vanguard and Awel y Môr projects. The only other big winner was SSE, for the next phase of its Berwick Bank project in the North Sea, currently the largest planned offshore wind farm in the world.

The government’s “contracts for difference” scheme guarantees developers a fixed price for electricity to protect them from market volatility. This auction result should help stabilise an industry that was running into problems.

After the disastrous collapse of projects like the proposed Hornsea 4 wind farm last year, the government tweaked the rules for this round of auctions to prioritise deliverability over costs. It also extend guaranteed revenue contracts from 15 to 20 years, giving investors long-term certainty.

It’s a pragmatic move. By relying on established giants like RWE and prioritising projects that are actually likely to get built, the UK hopes to leave the era of high-profile collapses in the past.

Floating wind risks sinking

But this safety-first approach has left the more innovative end of the sector out in the cold.

Floating turbines are the next big thing in the wind industry. They enable electricity generation further offshore, where winds are even stronger and more consistent.

However, their low level of funding was already a talking point in the industry, and in these new auctions the budget for floating wind projects remained stagnant. Only two floating offshore wind farms have been awarded contracts, each a modest 100 megawatts (these days, a single big fixed-bottom turbine can generate about 15 megawatts).

The UK government has doubled down on established technology, but has missed a crucial chance to drive the standardisation floating wind will need before it can be deployed on a much larger scale.

Behind the bottleneck

But the ultimate problem is time.

The government’s clean power 2030 action plan sets the ambitious target of taking fixed-bottom offshore wind capacity from around 16GW today to nearly 50GW by 2030. The new 8.4GW may sound like a huge step towards that total, but signed contracts aren’t the same as actual turbines.

In the short-term, there are still serious bottlenecks. There aren’t enough of the huge and specialised ships needed to transport and deploy offshore wind farms. Grid connections are backlogged, and essential port upgrades can take a decade to complete.

Despite the government prioritising the most mature projects, doubling the budget at the last minute just adds even more capacity lined up behind these backlogs. In fact, the UK already has a significant pipeline of 96.4GW of offshore wind in various stages of development.

The newly-awarded projects will almost certainly not be generating power by 2030. Even with more investment in ports and supply chains, the timing is simply too tight.

The new auction demonstrates the balancing act between the need to grow confidence among investors and progress towards renewable energy generation targets.

Tweaks made to the auction design should result in fewer incidents like Hornsea 4 and will help revive a struggling industry, but political uncertainty is growing. In the UK, Reform is leading the polls and has promised to roll back net zero initiatives while, in the US, Donald Trump’s vendetta against offshore wind has resulted in legal battles that have global ramifications for the industry.

The industry needed a win and it got one. The new auction should ultimately deliver more wind farms. However, it won’t accelerate the transition to net zero. If the goal really is clean power by 2030, the government will need to do much more.

Voici ce que les dernières recherches révèlent sur le traitement hormonal de la ménopause et la santé cognitive

Source: The Conversation – in French – By Zahinoor Ismail, Professor, Cumming School of Medicine, University of Calgary

Au début des années 2000, une importante étude sur la santé des femmes, la Women’s Health Initiative (WHI), a fait la une des journaux. Lancée dans les années 1990 et toujours en cours, elle vise à déterminer si le traitement hormonal de la ménopause (THM), utilisé pour soulager leurs symptômes, pouvait également protéger contre des problèmes de santé graves survenant à un âge avancé.

Une sous-étude, la WHI Memory Study (WHIMS), s’est concentrée sur la santé cognitive des femmes ne souffrant pas de démence au départ.

La Conversation vous propose d’analyser sous toutes ses facettes l’impact du vieillissement de l’imposante cohorte des boomers sur notre société, qu’ils transforment depuis leur venue au monde.

Ses résultats, diffusés en 2002, ont provoqué un choc. Les personnes sous THM présentaient un risque accru de développer des maladies cardiaques, des accidents vasculaires cérébraux, des cancers du sein et de la démence. Les médecins ont rapidement déconseillé le THM, les ordonnances ont chuté et ce traitement a pratiquement disparu du débat public.

Les conclusions diffusées à l’époque étaient incomplètes. Les résultats de l’étude n’étaient pas faux, ils révélaient des risques réels. Mais au cours des années qui ont suivi, les chercheurs ont réexaminé les données, non seulement celles concernant le cerveau, mais aussi celles relatives au cœur, aux accidents vasculaires cérébraux et au cancer, afin de mieux comprendre quand, pourquoi et comment on devrait avoir recours au THM.

Aujourd’hui, les experts s’accordent à dire que pour de nombreuses femmes qui commencent ce traitement autour de la ménopause et qui n’ont pas de contre-indication médicale, les avantages l’emportent sur les risques. Dans de tels cas, le THM peut être prescrit en toute sécurité pour traiter les symptômes de la ménopause.

Pourtant, plusieurs mythes persistent, notamment concernant le vieillissement cérébral.

Nous allons examiner ici les principaux mythes à ce sujet.

Mythe n° 1 : le THM augmente le risque de démence chez toutes les femmes

Selon l’étude WHIMS, les femmes ayant commencé un traitement hormonal à 65 ans ou plus présentaient un risque accru de développer une démence par rapport à celles qui n’en avaient pas pris. Cependant, la plupart des femmes entreprennent un THM beaucoup plus tôt, généralement dans la quarantaine ou la cinquantaine, à la périménopause.

Le moment où l’on débute le traitement est important.

Les chercheurs évoquent l’hypothèse d’une « fenêtre critique » : entreprendre un THM autour de la ménopause pourrait favoriser la santé cérébrale, tandis que le commencer plusieurs années plus tard pourrait augmenter le risque de déclin cognitif et de démence.

L’étude WHIMS n’a pas testé cette « fenêtre » : la plupart des participantes avaient dépassé depuis longtemps l’âge de la ménopause et ne présentaient plus de symptômes. Les résultats n’offrent donc pas de conclusion quant aux effets du traitement hormonal lorsqu’il est utilisé au bon moment et pour les bonnes raisons (présence de symptômes de la ménopause).

Des études récentes apportent un tableau nuancé : certaines femmes qui commencent un THM autour de la ménopause vont constater des bienfaits cérébraux plus tard dans leur vie, comme une meilleure mémoire et un risque de démence réduit. Pour d’autres, les résultats en termes de cognition et de risque de démence seront peu marqués, mais pas moins bons.

Cependant, entreprendre un THM plus tard, par exemple après 70 ans ou plus de cinq ans après la ménopause, peut être associé à une accumulation accrue de protéines Tau, marqueur de la maladie d’Alzheimer.

En résumé, le THM n’est pas nécessairement mauvais pour le cerveau, mais ses effets peuvent dépendre du moment où il est commencé et du type d’hormones utilisé.

Mythe n° 2 : tous les THM ont le même effet sur le cerveau

Lorsqu’on évoque le THM (anciennement connu sous le nom de traitement hormonal substitutif ou THS), on peut penser qu’il existe un traitement standard. Or, le THM se présente sous de nombreuses formes, et celles-ci changent la donne. Dans le cadre de l’étude WHIMS, les femmes recevaient des comprimés d’œstrogène équin, et de l’acétate de médroxyprogestérone si elles avaient un utérus. Cette combinaison était autrefois le traitement standard, mais elle est rarement utilisée de nos jours.

Aujourd’hui, on a plutôt recours au 17-bêta– œstradiol (un type d’œstrogène) qui est associé à des bienfaits pour le cerveau et à un risque moindre de déclin cognitif.

Les femmes avec un utérus prennent aussi un progestatif pour réduire le risque de cancer de l’utérus. Si les progestatifs peuvent favoriser la santé cérébrale, ils peuvent également atténuer les effets protecteurs des œstrogènes, notamment leur rôle dans la croissance, le maintien et le fonctionnement des cellules cérébrales qui soutiennent la mémoire et la pensée. Ainsi, le type et la combinaison des hormones ont leur importance.

Le mode d’administration du THM (comprimé, timbre, gel, crème, vaporisateur ou anneau vaginal) est important, car chacun est métabolisé différemment.

Les comprimés oraux passent par le foie et peuvent accroître le risque de formation de caillots sanguins et d’hypertension artérielle. Ces effets peuvent avoir des répercussions sur la santé du cerveau, en ralentissant le flux sanguin et en augmentant le risque d’AVC.

Les timbres et les gels, absorbés par la peau, présentent moins de risques, car ils contournent le foie.

En bref, tous les THM ne se valent pas. Mais si on a la forme et le moment appropriés, les THM peuvent-ils prévenir la démence ?

Mythe n° 3 : l’étude WHIMS a démontré que le THM pouvait prévenir la démence

Avec le temps, le THM est passé de traitement contre les symptômes de la ménopause à moyen de prévention de la démence. C’est l’étude WHIMS, qui visait à déterminer s’il pouvait réduire le risque de démence, qui a engendré cette vision.

Cependant, réduction des risques ne signifie pas prévention. L’étude WHIMS n’a pas évalué si le THM prévenait la démence. Comme elle portait sur des femmes longtemps après la ménopause, ses résultats ne permettent pas de savoir ce qui se produit lorsque le THM est administré pendant la transition ménopausique. Ses conclusions sont néanmoins utilisées pour étayer des affirmations plus générales sur le THM et la santé cérébrale, alors que ce traitement n’a jamais été conçu pour prévenir la démence ou servir de stratégie unique pour en réduire les risques.

Ce ne sont pas toutes les femmes qui ont besoin de suivre un THM, ou qui devraient le faire. Certaines traversent la ménopause sans difficulté, tandis que d’autres rencontrent davantage de problèmes. Le traitement hormonal n’est pas une solution universelle.

Mais pourquoi certaines femmes présentent-elles des symptômes et d’autres non ? De nouvelles recherches suggèrent que les symptômes de la ménopause pourraient fournir des indices sur la santé du cerveau, reflétant sa sensibilité à la baisse du taux d’œstrogènes. Comme les œstrogènes influencent la mémoire, la réflexion et l’humeur, un nombre plus important de symptômes pourrait indiquer une vulnérabilité accrue au vieillissement cérébral.

Il ne s’agit pas seulement des symptômes, mais aussi de leur impact sur la vie quotidienne. Lorsque les sueurs nocturnes perturbent le sommeil ou que les changements d’humeur mettent à rude épreuve les relations sociales, le stress et la fatigue peuvent être néfastes pour le cerveau.

En résumé, le THM n’est pas un remède miracle contre la démence. Toutefois, la prise en charge des symptômes de la ménopause peut contribuer au bien-être actuel et à la santé cérébrale future des femmes qui souffrent et peuvent avoir recours à ce traitement.

Et la suite ?

L’étude WHIMS a marqué une étape importante dans l’histoire du THM, mais la recherche continue d’évoluer.

Les scientifiques se posent les questions suivantes : quel est le meilleur moment pour entreprendre un THM ? Quelles sont les hormones les plus importantes ? Qui en bénéficie et pourquoi ?

La ménopause est différente pour chaque femme. Pour certaines, le traitement hormonal apporte un soulagement et améliore la qualité de vie. Il n’offre toutefois aucune garantie contre la démence. Mais pour les personnes qui en ont besoin, le THM commencé au bon moment peut favoriser un vieillissement cérébral sain, ce qui est encourageant pour la prochaine génération qui entre dans l’âge mûr avec plus de connaissances et de soutien que jamais.

28 Years Later: The Bone Temple explores the legacy of shared trauma on the national psyche

Source: The Conversation – UK – By Matt Jacobsen, Senior Lecturer in Film History in the School of Society and Environment, Queen Mary University of London

Few long-running horror franchises manage to feel both expansive and intimate. The Bone Temple, the second film in a projected trilogy revisiting the world of classic British horror 28 Days Later, achieves exactly that balance.

The Bone Temple is a brilliant example of a well-told, powerful yet small-scale story operating confidently within the parameters of an existing franchise. With this film, American film-maker Nia DaCosta takes the directorial reins from Danny Boyle and puts her unique stamp on the series. Working from writer Alex Garland’s screenplay, she has created a wonderfully off-kilter, wild horror film about survival and the legacy of shared trauma on the national psyche.

In the world of the franchise, Britain has been overrun with the hyper-contagious “rage” virus, resulting in hordes of violent infected.

Garland and Boyle changed the zombie genre forever in 28 Days Later (2002) by making the traditionally shambling creatures fast-moving and aggressive. This newest film follows the example set by the first film by asserting that the most immediate threat following the collapse of civilisation may not be the zombies themselves but fellow survivors, irrevocably altered by the breakdown of society.

Returning from the excellent, bracing 28 Years Later (2025) are teenage Spike (Alfie Williams) and former GP Ian Kelson (Ralph Fiennes). The hauntingly beautiful and brilliantly conceived bone temple of the title is Kelson’s monumental construction, first revealed in 28 Years Later. It’s a sprawling series of obelisks made from the bones of the dead, created as a memorial to the loss of British life.

The trailer for 28 Years Later: The Bone Temple.

In the last film’s most memorable and impressive scene, Spike ascends a tower of skulls to place and memorialise the remains of his mother (Jodie Comer). The act signifies a cultural commemoration and a momentary acknowledgement of grief and mourning that is usually unavailable to survivors living with uncertainty.

The Bone Temple follows two stories that converge inevitably and explosively in a startling climax. In the first, Kelson forms an unexpected bond with the “Alpha” – an infected man he names Samson – and the discoveries he makes about the rage virus in the process. The other follows Spike’s encounter with the group of survivors called The Jimmys, named and styled by their leader Jimmy Crystal (Jack O’Connell) after British celebrity Jimmy Savile.

Sporting Savile’s trademark tracksuit, platinum blonde wig and gold chains, the group are trained in martial arts. Crystal is convinced he is the offspring of Satan – as teased in the superbly baffling final minutes of the previous film.

Savile, the formerly well-loved presenter of Jim’ll Fix It – the BBC programme that delivered life-changing experiences to needy children – was revealed to be a serial child sex offender in 2012, a year after his death. In the film’s world, where society collapsed in 2002, Savile is still an apparently charitable if eccentric personality.

It is deeply unsettling and uncomfortably humorous seeing his tarnished image animated so aggressively in acts of extreme violence. A version of his catchphrase “Howzat!” is uttered by the group in cultish reverence.

Through The Jimmys and their peculiarly brutal, ritualised existence, DaCosta’s tragic film is concerned with the psychological effect of collective trauma and suffering.

DaCosta’s brilliance

DaCosta has spoken about Garland and Boyle’s encouragement that she take creative control and put her stamp on the material, and about her attitude to making this film as “letting her freak flag fly”.

She has certainly delivered on that promise. This is a brilliantly strange film that is continuously surprising and provocative despite its small-scale storytelling.

I would be surprised if anything else at the cinema in 2026 can match the bizarre spectacle of The Bone Temple’s best sequence. In a tour de force of over-the-top theatrics that is as joyously silly as it is visionary, Fiennes gives a career highlight performance, complemented by pyrotechnics and set to the searing riffs of Iron Maiden’s heavy metal anthem The Number of the Beast.

DaCosta’s treatment of location plays a key role in defining the eerie, unsettling character of The Bone Temple. While the director’s father is British-born and raised and she visited the UK regularly during her childhood, as an American she brings an outside perspective and sense of wonder to the northern British rural landscape.

Where 28 Days Later gained its critical reputation from the melancholy uncanniness of dilapidated urban spaces fallen into disrepair, this film is set entirely in the lush, dramatic pastoral environments of Cumbria.

DaCosta intersperses the action of the film with deeply unsettling, atmospheric shots of the countryside. The choice recalls the mythic strangeness of influential folk horror films Witchfinder General (1968) and The Wicker Man (1973).

More so than any other film genre, horror pushes boundaries and it must evolve to stay relevant and potent. DaCosta and Garland follow that ethos and have crafted a continuously surprising, spiky and abrasive take on familiar elements of folk horror and the zombie film.

The Bone Temple stands proudly within the recent wave of acclaimed horror films including Weapons and Bring Her Back as a bold and original experience that genre fans will celebrate.

Governments are rushing to embrace AI. They should think twice

Source: The Conversation – UK – By Akhil Bhardwaj, Associate Professor (Strategy and Organisation), School of Management, University of Bath

Governments across the world want AI to do more of the heavy lifting when it comes to public services. The plan is apparently to make make things much more efficient, as algorithms quietly handle a country’s day to day admin.

For example, AI might help tackle tax fraud, by working out ways of targeting those most likely to be offending. Or it might be to help public health services screen for various cancers, triaging cases at scale and flagging those deemed most at risk.

But what happens when such a triaging system makes a mistake? Or when government agencies deploy AI to identify fraud and the model simply gets it wrong?

There is already sobering evidence that AI errors can have devastating consequences. In the Netherlands for example, flawed algorithmic assessments of tax fraud were dealt with in ways which tore families apart and separated children from their parents.

In that case, a risk‑scoring system was used to identify families it deemed likely to be committing benefits fraud. It then fed these assessments into automated operations that ordered repayments, driving innocent households into financial ruin.

So states should be extremely wary of substituting human judgement with AI. The assumption that machines will almost always get it right is simply not true. People’s lives cannot be easily reduced to data points for algorithms to draw conclusions from.

And when things do go wrong, who is responsible? What happens to human accountability?

These are the kind of questions that have often been overlooked amid all the clamour – and vast levels of investment – that AI has attracted. Yet even if we set aside the possibility that this is another speculative bubble ready to burst, there is growing evidence that AI in its current form does not deliver what it promised. The problem of “hallucinations” – when AI generates plausible yet nonfactual content – [remains unresolved] [https://dl.acm.org/doi/pdf/10.1145/3703155], and expensive developments have often been underwhelming.

Even leading figures in the industry, including the co-founder of OpenAI have acknowledged that that simply making large language models (LLMs) larger will not improve things significantly.

Yet these systems are rapidly being embedded into key sectors of our lives, including law, journalism and education.

It’s not even that hard to imagine a future university where lectures and assignments are generated by LLMs operated by a particular faculty, to be absorbed and completed by LLMs operated by students. Human learning could then become a byproduct of machine-to-machine communication, and the long-term consequence could be that critical thinking and expertise are hollowed out in the very institutions charged with cultivating them.

All In?

But all of this integration is highly profitable for AI companies. The more AI is woven into public infrastructures and business operations, the more indispensable these firms become, and the harder they are to challenge or regulate.

Integration into the defence sector for example, with the development of autonomous weapons could simply make a firm too big to fail, if a country’s military security depended on it.

And when things go wrong, the asymmetry of expertise between governments and citizens on one side, and AI developers on the other, simply increases the overall reliance on the very firms whose systems created the problems in the first place.

To understand where this trajectory might lead, it’s worth looking back a couple of decades to when social media companies first appeared, apparently with the simple goal of connecting people across the world.

Today though, the reach and power of some of those firms is the source of major concerns around privacy, surveillance and manipulation. There have been scandals on everything from undermining democracy and spreading misinformation to inciting violence.

Yet we now find ourselves experimenting with a potent mix of social media, AI and machine learning. Social media feeds on attention while LLMs can generate vast amounts of attention grabbing content. Meanwhile, machine learning systems determine what each of us sees on our various screens, trapping us in ever tighter informational bubbles.

So even if, for the sake of argument, AI evolves as promised, becoming more accurate, more robust and more capable, should we really be ceding control over more domains of life to algorithmic coordination in pursuit of order and efficiency?

Technology alone cannot resolve social, economic or moral problems. If it could, children would not go hungry in a world that already produces enough food to feed everyone.

Critics of AI are often dismissed as Luddites. But this is a misreading of history. Luddites, the 19th-century English textile workers who opposed some automated machinery in the mills where they worked, were not opposed to technology per se.

They were simply opposed to its misuse and unreflective deployment, and sought a deeper examination of how technology reshapes work, communities and everyday life. Some 200 years later, surely that remains a reasonable demand.

Wikipedia at 25: can its original ideals survive in the age of AI?

Around the turn of the century, the internet underwent a transformation dubbed “web 2.0”. The world wide web of the 1990s had largely been read-only: static pages, hand-built homepages, portal sites with content from a few publishers.

Then came the dotcom crash of 2000 to 2001, when many heavily financed, lightly useful internet businesses collapsed. In the aftermath, surviving companies and new entrants leaned into a different logic that the author-publisher Tim O’Reilly later described as “harnessing collective intelligence”: platforms rather than pages, participation rather than passive consumption.

And on January 15 2001, a website was born that seemed to encapsulate this new era. The first entry on its homepage read simply: “This is the new WikiPedia!”

Wikipedia wasn’t originally conceived as a not-for-profit website. In its early phase, it was hosted and supported through co-founder Jimmy Wales’s for-profit search company, Bomis. But two years on, the Wikimedia Foundation was created as a dedicated non-profit to steward Wikipedia and its sibling projects.

Wikipedia embodied the web 2.0 dream of a non-hierarchical, user-led internet built on participation and sharing. One foundational idea – volunteer human editors reviewing and authenticating content incrementally after publication – was highlighted in a 2007 Los Angeles Times report about Wales himself trying to write an entry for a butcher shop in Gugulethu, South Africa.

His additions were reverted or blocked by other editors who disagreed about the significance of a shop they had never heard of. The entry finally appeared with a clause that neatly encapsulated the platform’s self-governance model: “A Wikipedia article on the shop was created by the encyclopedia’s co-founder Jimmy Wales, which led to a debate on the crowdsourced project’s inclusion criteria.”

As a historical sociologist of artificial intelligence and the internet, I find Wikipedia revealing not because it is flawless, but because it shows its workings (and flaws). Behind almost every entry sits a largely uncredited layer of human judgement: editors weighing sources, disputing framing, clarifying ambiguous claims and enforcing standards such as verifiability and neutrality.

Often, the most instructive way to read Wikipedia is to read its revision history. Scholarship has even used this edit history as a method – for example, when studying scientific discrepancies in the developnent of Crispr gene-editing technology, or the unfolding history of the 2011 Egyptian revolution.

Co-founder Jimmy Wales explains how Wikipedia was created, July 2005. Video: TedX.

The scale of human labour that goes into Wikipedia is easy to take for granted, given its disarming simplicity of presentation. Statista estimates 4.4 billion people accessed the site in 2024 – over half the world and two-thirds of internet users. More than 125 million people have edited at least one entry.

Wikipedia carries no advertising and does not trade in users’ data – central to its claim of editorial independence. But users regularly see fundraising banners and appeals, and the Wikimedia Foundation has built paid services to manage high-volume reuse of its content – particularly by bots scraping it for AI training. The foundation’s total assets now stand at more than US$310 million (£230 million).

‘Wokepedia’ v Grokipedia

At 25, Wikipedia can still look like a rare triumph for the original web 2.0 ideals – at least in contrast to most of today’s major open platforms, which have turned participation into surveillance advertising.

Some universities, including my own, have used the website’s anniversary to soothe fears about student use of generative AI. We panicked about students relying on Wikipedia, then adapted and carried on. The same argument now suggests we should not over-worry about students relying on generative AI to do their work.

This comparison is sharpened by the rapid growth of Elon Musk’s AI-powered version of Wikipedia (or “Wokepedia”, as Musk dismissively refers to it). While Grokipedia uses AI to generate most of its entries, some are near-identical to Wikipedia’s (all of which are available for republication under creative commons licensing).

Grokipedia entries cannot be directly edited, but registered users can suggest corrections for the AI to consider. Despite only launching on October 27 2025, this AI encyclopedia already has more than 5.6 million entries, compared with Wikipedia’s total of over 7.1 million.

So, if Grokipedia overtakes its much older rival in scale at least, which now seems plausible, should we see this as the end of the web 2.0 dream, or simply another moment of adaptation?

Credibility tested

AI and the human-created internet have always been intertwined. Voluntary sharing is exploited for AI training with contested consent and thin attribution. Models trained on human writing generate new text that pollutes the web as “AI slop”.

Wikipedia has already collided with this. Editors report AI-written additions and plausible citations that fail on checking. They have responded with measures such as WikiProject AI Cleanup, which offers guidance on how to detect generic AI phrasing and other false information.

But Wales does not want a full ban on AI within Wikipedia’s domain. Rather, he has expressed hope for human-machine synergy, highlighting AI’s potential to bring more non-native English contributors to the site. Wikipedia also acknowledges it has a serious gender imbalance, both in terms of entries and editors.

A video made by Wikipedia to mark its 25th anniversary.

Wikipedia’s own credibility has regularly been tested over its 25-year history. High-profile examples include the John Seigenthaler Sr biography hoax, when an unregistered editor falsely wrote about the journalist’s supposed ties to the Kennedy assasinations, and the Essjay controversy, in which a prominent editor was found to have fabricated their education credentials.

There have also been recurring controversies over paid- or state-linked conflicts of interest, including the 2012 Wiki-PR case, when volunteers traced patterns to a firm and banned hundreds of accounts.

These vulnerabilities have seen claims of political bias gain traction. Musk has repeatedly framed Wikipedia and mainstream outlets as ideologically slanted, and promoted Grokipedia as a “massive improvement” that needed to “purge out the propaganda”.

As Wikipedia reaches its 25th anniversary, perhaps we are witnessing a new “tragedy of the commons”, where volunteered knowledge becomes raw material for systems that themselves may produce unreliable material at scale. Ursula K. Le Guin’s novel The Dispossessed (1974) dramatises the dilemma Wikipedia faces: an anarchist commons survives only through constant maintenance, while facing the pull of a wealthier capitalist neighbour.

According to the critical theorist McKenzie Wark: “It is not knowledge which is power, but secrecy.” AI often runs on closed, proprietary models that scrape whatever is available. Wikipedia’s counter-model is public curation with legible histories and accountability.

But if Google’s AI summaries and rankings start privileging Grokipedia, habits could change fast. This would repeat the “Californian ideology” that journalist-author Wendy M. Grossman was warned about in the year Wikipedia launched – namely, internet openness becoming fuel for Silicon Valley market power.

Wikipedia and generative AI both alter knowledge circulation. One is a human publishing system with rules and revision histories. The other is a text production system that mimics knowledge without reliably grounding it. The choice, for the moment at least, is all of ours.

Elderly men sentenced to life in jail reflect on the reality of growing old behind bars

We were standing by a large white board in one of the prison’s educational areas, debriefing how our study on hope had gone when the man slipped into the room without a sound. Like the other participants he was over 60, and serving a life sentence. He had grey hair, and was very tall and slim.

He slowly picked up a chair before slamming it down. I invited him to join us, but he stayed still while the others watched. Then he dragged the chair across the floor with a piercing scrape. I could hear my own pulse.

As I began to speak I noticed he was crying. At first, it sounded like a whisper of sobs, but then it got louder. He rose abruptly, and came up close to me. I wrote in my fieldwork notes from that day:

My heart is racing. He asks, towering over me: ‘How dare you ask us about hope.’ The alarm blares. Guards escort him out. The others sit in stunned silence, eyes locked on us, waiting for a reaction.

In the months that followed, I would meet many other men for whom hope was not necessarily a lifeline as is so commonly assumed, but a burden that they had to carry, sometimes painfully.


The Insights section is committed to high-quality longform journalism. Our editors work with academics from many different backgrounds who are tackling a wide range of societal and scientific challenges.


Hope is not a soft word in prison. It shapes how people cope with their sentence and it determines whether – and how – they engage with staff and other prisoners. It shapes whether they commit to vocational and educational activities, and it sustains connections with people on the outside.

For older life-sentenced prisoners specifically, hope becomes interlinked with accelerated ageing, with bullying from younger prisoners, and with the fear of release into an unknown world.

Some people may think these men do not deserve hope. But the places that extinguish it do not produce safer prisons. Instead, they produce people who are damaged, isolated, and less capable of reintegrating into society.

The hope project

My project (In search of Hope: the case of elderly life-sentenced prisoners) began in August 2022. We were investigating how the “right to hope” – as defined by Judge Ann Power-Forde in her concurring opinion to the European Court of Human Rights judgment Vinter and others v the UK (2013)– translates behind prison walls for older people serving life sentences, many of whom face slim prospects of release due to their advanced age and the length of their prison sentence.

The research was carried out across three English prisons over 12 months by myself and research associate, Helen Gair, with a small team of research assistants. We conducted fieldwork in a Category A prison (reserved for people presenting the highest levels of risk), a Category C (mid-security level prison, often aimed at training and resettlement), and a Category D (open prison or the last stage before release).

Each facility had its own smell and sound. The spatial layout and daily rhythm varied too. For instance, the high security site was an old red brick Victorian building, and the wings were arranged in a half panopticon (circular) design. Outside the main block, guard dogs were walked on a strip of green that ran along a ten-metre-high wall. Inside it was loud; lockdowns were frequent, and it smelled of sweat and mould.

In the open prison, the smell of cannabis drifted through the grounds. Men greeted us in grey tracksuits, often carrying disposable cups of tea. There were ducks and a pond and a RAF plane on display.

In the Category C prison, we often got lost. The alphabetical alignment of buildings made little sense to us. We had our own set of keys which meant we could move around independently. However, rusty locks slowed us down often, and every gate and door had to be opened and closed behind us.

Men aged 50 and above and serving life sentences were invited to participate. We collected diaries, completed ethnographic prison observations, and ran one-to-one interviews with each participant.

Additionally, interviews were conducted with prison staff, both working in frontline and office-based roles, to get a sense of how those who work closest to ageing life-sentenced prisoners perceived hope and whether prison practices preserved or restrained it. Overall, we wanted to find out how hope was experienced by prisoners and how it was handled as a prison practice.

Idealised hope v prison reality

In the 2010s, a case was brought before the European Court of Human Rights by Jeremy Bamber, Douglas Vinter and Peter Moor. They had each been convicted of murder in the UK and been given whole-life orders – the most severe form of life sentence.

This means that by law, they were sentenced to spend the rest of their lives in prison with no minimum term set for parole or release. Only a small percentage of people get such severe sentences: Myra Hindley and the Yorkshire Ripper Peter Sutcliffe being two examples.

On July 9, 2013, the human rights court ruled that whole-life orders which do not include any prospect of release or review would amount to inhuman or degrading treatment, contrary to Article 3 of the European Convention on Human Rights. The notion of a “right to hope” was first mentioned by Judge Ann Power-Forde’s concurring judgment:

… Even those who commit the most abhorrent and egregious of acts … nevertheless retain their essential humanity and carry within themselves the capacity to change. Long and deserved though their prison sentences may be, they retain the right to hope that, someday, they may have atoned for the wrongs which they have committed. They ought not to be deprived entirely of such hope. To deny them the experience of hope would be to deny a fundamental aspect of their humanity and to do that would be degrading.

The right to hope is thus vested in a possibility of release and review. What this means is that there must be a realistic possibility that any prisoner sentenced to life imprisonment be considered, at some point in time, for release or that the justification for their continued detention needs to be reviewed.

But how does the right to hope account for the fact of ageing in prison?

The rapid and global “greying” of the prison population indeed complicates the human rights jurisprudencial understanding of a right to hope. As of March 2025, there were 87,919 people in prison in England and Wales, with nearly one in five (18%) aged 50 or older, according to the Ministry of Justice.

Compounding matters, life-sentenced prisoners now make up around 10% of the sentenced population, and this group is ageing rapidly. Almost a third of “lifers” are over 50. As a result, old, life-sentenced prisoners are the fastest-growing subgroup in the system.

This phenomenon combined with the current overcrowding crisis produces a range of managerial and ethical challenges: bed spaces are tied up for decades, healthcare and social care demands are on a steep rise, and the pressures on ill-equipped prison staff increase.

The myth of prison release

One important finding from our project is that parole and the possibility of release during a prisoner’s life span becomes somewhat of a myth for those serving life sentences at an advanced age. Usually, life-sentenced prisoners are given a minimum tariff, which is a period when they are not eligible for parole. This legal principle does not account for age however. Dean, 62 , was a life-sentenced prisoner at the Category A prison who had served six years. He told us how unrealistic parole felt in light of his age:

I will be 80 years old before my first parole hearing and in all honesty I don’t know if I will reach that milestone. Although my health is reasonable, I’m on all kinds of medication to keep me going but incarceration has a way of dragging you down so I am not optimistic.

Trevor was 73 when we interviewed him in the Category C prison and had been inside for 27 years. He was sat in a wheelchair and had an elastic band wrapped around his middle finger and thumb. He explained to us that it helped him hold a pen.

He described years of postponed parole hearings, medical delays, and transfers to lower security prisons being denied because his health needs could not be met in open prison conditions. He asked us simply:

If you were in my situation would you live in hope or would you resign yourself to your future?

The experience of no longer believing in release is supported by official data that shows that few prisoners sentenced to life get released during their lifetime.

One in five lifers are now beyond their tariff, often by several years with age-related barriers to parole contributing to prolonged incarceration. What we noticed during fieldwork was that older prisoners often struggled to access or complete accredited programmes because of mobility issues and cognitive impairment, but also due to managerial prioritisation of younger prisoners or those convicted of shorter sentences.

Rising deaths in England and Wales among older prisoners further underscores the illusory prospect of release.

Nearly nine in ten of the 192 deaths from natural causes in the year 2025 involved older prisoners and the number of people in prison requiring palliative care continues to grow.

From 2016 to 2020, hospitals recorded 190 admissions of older male prisoners with a palliative care diagnosis. In roughly 40% of those cases, cancer was the main condition on entry. The charity, Inquest, reported in 2020 that many of the deaths in prison were neither inevitable nor unforeseeable, pointing instead to systemic failings in healthcare provision, communication, emergency intervention, and medication management.

Building on this, academic scholars Philippa Tomczak and Ròisìn Mulgrew argued that classifying deaths in custody as “natural” obscure the ways in which prison environments contribute to deaths that might otherwise have been avoided.

Additionally, research has repeatedly linked self-harm and suicide patterns to experiences of hopelessness and social isolation. The participants in our study similarly tied the removal of hope to suicides, citing examples they had witnessed in prison.

In his prison diary, a participant with thick rectangular glasses called Ian, 65, who had served 33 years of his life sentence and was now held in a Category C prison, wrote:

With the absent (sic) of hope you have despair. I have known prisoners who have committed suicide, they had no hope or expectations only misery and despair.

So there appears to be a contradiction between the legal possibility of release and its practical improbability in the context of old and ageing, life-sentenced prisoners.

The fear of release

Beyond the practical improbability of release, many participants described how much they feared the world they would hypothetically re-enter one day. Several participants in their 60s and 70s reflected on how they no longer recognised the world outside.

For them, the time spent in prison combined with their physical and cognitive decline has institutionalised them. They felt they could not fare alone outside prison rules and environments. One man named Roy, who had spent decades in various Category A prisons wrote in his diary:

I have no hope of, or real wish to leave prison, where I am now completely institutionalised, I have no responsibilities other than abiding by prison rules, and few expenses.

Another frail-looking man named Russell, 68, described in his diary (which he completed from his Category C cell) how the very idea of a future had become hollow: “It’s difficult really because like I say, I haven’t got any hope of getting out of prison as far as I’m concerned. That is it. I’m in prison and that’s as far as it will go.”

Practical matters such as technological advances and housing also made the very thought of release overwhelming. Gary, 63, who had served 24 years, wrote poignantly about his fears of release, saying: “Release frightens me because of the label that has been firmly given to me and that brings its own problems. Where will I live? How will I live?”

A 73-year-old participant named Kevin, who was transferred during the project from a Category C to an open prison, spoke about how, after 21 years in prison, things will have changed too much on the outside for him to deal with. As he stood on the doorstep of freedom, he worried about getting his head around new technology and accessing simple things like his pension. He said: “Technology has moved on at a phenomenal pace, seems very scary to me … I should stay here in prison where everything is regulated and structured rather than going out to something that is quite alien to me.”

These feelings are exacerbated by the erosion of social networks, the death of family and friends, and the disappearance of any meaningful horizon. Social isolation means that the world they would be reintegrating into has become alien and they will have to navigate it mostly alone. Kevin added:

People that I used to call friends no longer want to know me or have died. One thing for sure that I can [say] is true, you certainly find out who your true friends are … when you come to prison and especially if you come to prison for a long time.

This sense of destroyed horizons, where release holds no promise and the outside world has become even more terrifying than the cell, has been dramatised in popular culture.

In The Shawshank Redemption (1994) the character Brooks, released after 50 years inside, finds himself unable to cope with the pace and impersonality of the modern world. His suicide becomes a haunting metaphor for the crushing effect of institutionalisation that hollows out the self and the possibility of meaningful social reintegration.

When hoping becomes harmful

Other prisoners we spoke to seemingly decided it was more beneficial for them to give up on hope altogether. Some – like Barry -– wondered if giving up on hope of release would be less torturous.

Barry was 65 when we spoke to him and has spent over four decades in prison on a life sentence. He’s tall and slim. When he walked in, we noticed he had a limp and used a cane. The first time we met, he sat with his hands clasped, speaking in a measured voice that occasionally broke into a laugh, not from humour but more from what I felt like was exhaustion. Though parole is technically available to him, he has come to see the pursuit of release not as hopeful but as harmful.

Over years of disappointments, Barry wondered if living with no hope would be less painful and felt it had become “pointless” to hope. He wrote in his diary:

Hope is when I want something to happen or something to be true … I often ask myself would it be kinder to live with no hope and just live with a ‘wait and see’ kind of attitude.

Indeed, every parole hearing postponed, every dashed expectation had eroded the value of hoping. Ultimately, giving up on hope is captured as something that eventually preserves mental health. As Barry added:

An empty case of hope is healthy, I say that because of the amount of men I have seen become ill; disappointment becomes despair, becomes depression, becomes mental ill health … then when you stop hoping, you start to recover and you no longer feel hopeless, as you are not hoping for anything. So hope is a paradox, it can disappoint or make you feel there is a real possibility of things to come.

He recalled reading about an American woman sentenced to life without parole who had begged for the death penalty instead. Her explanation (“I don’t just want to be alive, I want to be able to live”) resonated with him so powerfully that he said it, “almost knocked me off my chair”. He recognised in her plea the same cruel paradox he faced: that to prolong his existence in hopeless conditions was no life at all. His conclusion was irrevocable:

I understand more than most the need for hope, but all the years that I have been in prison and all the hopes I have had destroyed, I see hope as an enemy.

But then Barry equally admitted that he still hoped, no matter what. His hope was like a human natural reflex, over which he had no control, it just happened. He said: “We all hope … I hope I’ll get out on my next parole.”

What then, is hope in prison? Is it cruel and torturous or is it a human feature that brings relief and drive?

Recalibrating hope

We found hope meant different things to different people. It is not just about release. Some needed detailed plans, others focused on the day to day. Sometimes hope shifted towards modest goals that are tied to imagined places outside prison: a quiet retirement, a chance to study, to garden.

Terry was 65 and had served 38 years in category A prison. He told us that all he hoped for was “a quiet life in retirement”, while Russell, who was about the same age but had served over 12 years and was in a Category C when he wrote his diary, said that he hoped to, “… someday be released and to live the remaining years I have left in a small bungalow with a small garden in a village miles away from my old area of England. Have a pet cat.”

Others cast their hopes in more detailed and concrete plans about what the future would look like. Carl, 60, who enjoyed cooking and working out, for example, said he hoped to move in with his daughter and grandchildren for a while in an area where his ambition is to build his own house. He added: “I designed and roughly costed the development plan that helped to reinforce the hope that these plans were achievable.”

In the moment

But other participants recalibrated hope to more immediate aspirations set in the present, and in day-to-day encounters.

Barry said: “My hope is that I continue to live in the moment … You know, cause right now I’m in this office with you two guys, it’s calm. It’s nice. It’s peaceful. It’s a nice moment. But I’m not gonna think about what it’s gonna be like at 4pm because I might walk out that door and straight into a prison riot.”

Russell agreed, adding: “Looking for the future, I just go from one day to the next. It’s no good planning too far ahead.”

This shift of hope raises questions about how prisons shape and even limit the ways people can access and imagine their futures.

Another participant, Craig, who was 66 and had only served just over five years in the Category A prison when we met him wrote: “… you personalise hope to suit the circumstances.”

For the institution and those working in prison, these attitudes towards hope could be perceived as successful because prisoners sentenced to the longest sentences demonstrated a commitment to live a crime-free life, set in the present moment, focused on small menial things that will not raise any risk for management.

But when hope becomes so short-termist and bland, we are able to capture a shift in the very logic of imprisonment – one which is less about nourishing transformation aimed at resocialisation, and more about the life-long containment of decaying and dying bodies.

Hope matters

This article opened with a man telling my colleagues and I: “How dare you ask us about hope?” That moment has echoed throughout this study, both as an outburst that shows how prison research can be fraught with complexity but can also propel further and deeper reflection on humanitarian ideals such as hope.

When people in prison speak of the cruelty and fallacy of hope, you begin to wonder how much beauty and promise hope really holds in spaces of high control and constraint.

When transposed to prisons, hope no longer seems to be attached to an open horizon, evocative of lightness and liberty found anew. Instead, it represents dissociation from the outside world, and the cause of frustration, mistrust and a sense of abandonment.

Hope in prison exposes a disconnect between abstract legal humanitarian ideals and the empirical realities of ageing while incarcerated for long periods of time. And this claim could probably be extended to other settings of heightened regulation and tight monitoring, such as care homes, immigration detention centres, or even youth justice facilities.

The decision to depart from hope’s conventional, perhaps slightly romanticised meaning, and to recalibrate it towards real, daily conditions could nonetheless illustrate new ways for how older life-sentenced prisoners (and others under constraint) regain agency and keep going.

Ultimately, hope matters – not only for the people I met and interviewed – but also for broader society.

Imprisonment marked by hopelessness is linked to deteriorating mental and physical health, increasing pressure on prison healthcare and, upon release, on community health and social care services.

This is exacerbated for older prisoners released after decades inside. Hope is not a sentimental indulgence, but a condition that shapes whether imprisonment prepares people to live safely beyond prison or releases them with profound unmet needs. Regimes that erode hope risk merely displacing, rather than resolving, social harm.

Huntington’s disease: treatments are finally on the horizon after research breakthroughs

Huntington’s disease (HD) has long been impossible to cure, but new research is finally giving fresh hope. HD is a progressive, hereditary brain disease that affects movement, cognition and emotions. Doctors often diagnose HD when people show clear movement problems, typically around 30-50 years of age, after which patients live about 15-20 years.

The global prevalence of HD is about five per 100,000 people. While it is not as prevalent as Alzheimer’s disease, the disease starts much earlier in life, often when people are still in work and raising families.

Sadly, there is no cure. But a couple new research papers, by our team and others, suggests this may be about to change.

The causes of HD long remained a mystery since it was discovered in the 19th century. But in 1993, researchers uncovered that HD is caused by repetitive expansions of three DNA letters (C, A and G) in the Huntingtin (HTT) gene, resulting in the production of a mutant huntingtin protein.

This gene normally has a section that repeats the letters CAG over and over. In healthy people, the repeat is lower than 35. Repeat lengths greater than 39 will result in HD. The more repeats you have, the earlier symptoms usually start. In addition to your inherited CAG length, this sequence tends to continually expand in certain cells over a person’s lifetime, known as somatic expansion.

At the time, in 1993, the discovery generated lots of excitement. First, you could identify which relatives in a family with a history of the disease would develop it. Those of us working in HD clinics at the time were highly concerned about the ethical and mental health issues this also raised. There was a big need for counselling, for example. Second, it was thought, somewhat mistakenly, that very quickly there would be a treatment.

Many studies have investigated people with the HD gene expansion 15 years before onset and some even as far as 25 years before onset. Even before the onset of movement problems, changes in cognition, mood and the brain have been found.

In particular, the brain changes start in a part called the striatum, which helps control movement. Here, certain nerve cells (called GABAergic medium spiny neurons) die off. As HD gets worse, damage spreads to other areas like the cortex, which are important for cognition, and white matter, which connects brain regions.

Progress at last

Only recently has there been some promising results in the treatment of HD by clinical researchers Sarah Tabrizi and Edward Wild at University College London. Although, the research is still waiting to be peer reviewed and published, the results have been reported in a press release by uniQure, a US biotechnology company.

In this trial, a gene therapy, AMT-130, that reduces the production of the toxic mutant huntingtin protein was given to 29 HD patients with a definitive clinical diagnosis, between the ages of 25 and 65. The results showed slower cognitive decline on standard neuropsychological tests, particularly in processing speed and reading ability. Most significantly for doctors, cerebrospinal fluid levels of a protein called neurofilament light, a general marker for neurodegeneration, were reduced after three years follow-up, even below baseline levels.

This indicates that the therapy may actively protect brain cells from damage rather than simply masking symptoms. It is hoped that, in future, it will be possible to provide safe and effective treatments at earlier stages of the disease. Hopefully, people with the HD gene expansion will have improved cognition and emotion and reduced motor symptoms, which will improve quality of life and may even extend their lifespan.

This was a motivation for our new work, a collaboration between UCL and the University of Cambridge, for the HD- Young Adult Study. The study recruited 131 people: 64 with the HD gene expansion and 67 controls, long before predicted disease onset, approximately 24 years. The study gathered in-depth information about participants’ cognition, mood and behaviour, alongside brain scans and tests of blood and other fluids that can show how healthy their brain cells are.

At this early stage, we noted some increases in markers of neurodegeneration with limited effects on brain volume and cognition. Given that the striatal circuits are disrupted early in HD, we wanted to determine whether cognitive flexibility, how easily people can swap between different approaches and perspectives, a function that relies on this circuitry, was affected at this very early stage in those with HD gene expansion.

Indeed, we showed some mild early disruption to cognitive flexibility, which was associated with alterations in the connectivity in these circuits. This cohort was also followed up about 4.5 years later, where changes in many measures became more apparent.

Importantly, in collaboration with the University of Glasgow, we showed that somatic expansion, how the CAG sequence tends to continually expand in certain cells over a person’s lifetime, can give crucial information. This study was the first to show in living humans the faster this somatic expansion, the faster the disease progresses. This can explain why some people who have identical inherited CAG length in the Huntingtin gene can still have different onset of the disease.

Cognitive deficits were apparent at this time, although they were in a specific cognitive process. Our findings reveal early sustained attention deficits in people with expanded CAG sequences, which are associated with changes in brain circuits in the inferior frontal gyrus (involved in attention) well before movement was affected.

Intriguingly, this brain area is also linked to the inability of people with ADHD, to focus their attention, as we discovered in an earlier study. This suggests that this disruption in sustained attention in HD may reflect a neurodevelopmental process rather than a neurodegenerative one at this early stage of the disease.

These findings suggest that there is a treatment window, potentially decades before motor symptoms are present, where those with the HD gene expansion are functioning normally despite having detectable measures of subtle early neurodegeneration.

Identifying these early markers of disease is essential for future clinical trials in order to determine whether a treatment is having any effect and preserving the quality of life. In addition, as drugs that slow the worsening of the disease rather than treat the symptoms, are approved by the regulatory bodies for HD, they could be implemented at an early stage to improve quality of life and wellbeing.

We hope that these now rapid advances in the understanding and treatment of HD will, in the near future, bring great benefits to patients.
