Primero, el chasquido de la chapa al abrirse. Después, burbujas que ascienden lentamente. Luego viene el brindis, el primer sorbo, el juego de sabores, algunas veces más amargo, otras más dulce. Sea dorada, ámbar u oscura, detrás de cada cerveza hay una historia que, normalmente, implica desarrollos que nacen en un laboratorio y recorren un largo camino hasta llegar al paladar del consumidor, que es quien finalmente elige qué cerveza bebe, cómo, dónde y con quién.
Según las estimaciones de la empresa de investigación de mercado Mordor Intelligence, el volumen de negocio de la cerveza alcanzará los 914 210 millones de dólares en 2029. De ahí que las apuestas por el sector no cesen y que esa bebida ancestral que ya conocían los egipcios en la antigüedad continúe su evolución para ofrecer a millones de consumidores variaciones de presentación, sabor y experiencia.
Las investigaciones han dado como resultado un producto que los consumidores pueden preparar en casa, de forma casi instantánea. Además, encontramos una técnica de concentración que permite potenciar los sabores.
Se trata de separar el agua de la cerveza mediante un proceso de crioconcentración, es decir, enfriándola para formar cristales de hielo y luego separarlos. Así conseguimos una cerveza reconstituible. Es decir, una bebida alcohólica instantánea, líquida, densa y concentrada disponible en una presentación pequeña, como las cápsulas de café.
Es decir, la cerveza llegará al consumidor en una pequeña cápsula con líquido. Al mezclar dicho líquido con agua fría y gasificarlo en una maquina gasificadora casera se obtiene la cerveza original sin perder la concentración, guardando las mismas propiedades de una cerveza no instantánea.
Este nuevo desarrollo de producto ofrece ventajas como la reducción en costes de trasporte, que resultará más sencillo al no tener que contar con el peso del líquido total y la botella de vidrio o lata. En cuanto a conservación, el asunto también se simplifica, pues al ocupar menor espacio en el refrigerador es posible considerar un ahorro energético.
Más concentración y nuevos sabores
La segunda patente que ha resultado del trabajo de investigación ha sido la mejora de la calidad de la cerveza, aumentando su concentración. Lo hemos conseguido aplicando procesos en frío.
¿Y por qué frío? La mejor manera de comprenderlo es pensar en una sopa. Cuando necesitamos que sea más espesa, podemos calentarla por más tiempo hasta lograr la densidad deseada. Pero la situación cambia cuando se trata de hacerlo con un zumo de naranja: al someter este al calor, el sabor cambia significativamente y los aromas se pierden. Con nuestra tecnología es posible retirar el agua que está dentro de la cerveza, dejando un líquido que queda más concentrado.
Inicialmente, uno de los grandes desafíos consistía en lograr conservar el alcohol en el proceso. Para ello, se recurrió a pruebas en los laboratorios del Doctorado en Ingeniería de la Universidad de La Sabana y en el laboratorio de la Universidad Politécnica de Cataluña a través de proyectos de investigación a nivel de Doctorado y Maestría.
Tras analizar los resultados, tomamos la decisión de explorar nuevas posibilidades en la cerveza industrial. El objetivo era claro: aumentar la concentración para intensificar los sabores y descubrir nuevos matices.
La idea detrás del proceso es sencilla. Al reducir parcialmente el agua, los sólidos que aportan sabor, los compuestos volátiles y el alcohol se concentran más. Como resultado, la cerveza adquiere un perfil sensorial más intenso, con aromas y sabores más definidos.
Pero la investigación no se detuvo ahí, pues optamos por aplicarla en la cerveza artesanal, un producto con menos procesos de filtración. Así se abrió la puerta a nuevas formas de realzar sus cualidades, logrando que tanto la cerveza industrial como la artesanal puedan ofrecer experiencias más profundas y atractivas para todo tipo de consumidores.
Impacto en la industria
En definitiva, hemos desarrollado una línea de investigación poco estudiada a nivel mundial: la innovación en la crioconcentración. Aplicada al campo de la industria cervecera, permite mejorar procesos y diversificar productos. De este modo se abren nuevas oportunidades de negocio, promoviendo la generación de empleo y ofreciendo a los consumidores la posibilidad de disfrutar de una nueva experiencia en la que pueden descubrir los sabores de una cerveza bien fría.

En España, el alumnado de primaria y secundaria cuenta con alrededor de 80 días de descanso en verano. Esto representa una diferencia importante respecto al resto de los países europeos: entre las seis semanas que tienen los niños en Dinamarca u Holanda, a las 14 semanas en algunas regiones italianas, la media de los países de nuestro entorno es de unas 10 semanas. Cada verano, por ello, nos planteamos si las vacaciones veraniegas suponen muchos días de “asueto” o, por el contrario, un descanso necesario.
La evidencia científica respalda la idea de que disfrutar de casi dos meses y medio de vacaciones podría tener un impacto no necesariamente positivo en los aprendizajes adquiridos por niños y niñas en estas etapas educativas. Incluso en periodos vacacionales más cortos, algunos estudios han observado pequeñas pero significativas pérdidas en áreas como la ortografía y la lectura.
Conocimientos procedimentales y práctica
Esto resulta lógico, pues las lectura, la escritura y las matemáticas son destrezas que, como todo conocimientos procedimentales, se aprenden y refuerzan con la práctica. Si no vamos a clase, las oportunidades para el desarrollo de estas competencias en el hogar son escasas.
Por eso, el conocimiento adquirido en la escuela puede perderse (lo que se conoce en la jerga educativa como “la pérdida de aprendizaje del verano”). De todos modos este desgaste, según varios expertos en el tema, no afecta a todo el alumnado por igual. Los niños y niñas procedentes de entornos con un nivel socioeconómico bajo o con un rendimiento académico inicial más bajo correrían un mayor riesgo. Pero el fenómeno es complejo y no se limita a estos grupos.
Fácil de revertir
Aun así, parece que esta pérdida es susceptible de revertirse al comienzo de curso. Tras el verano, se pueden dedicar unos días a acomodar los conocimientos y habilidades perdidos antes de progresar en el temario.
Las vacaciones permiten a las niñas y niños recargar energía y les ofrecen más oportunidades para ejercer su autonomía y tomar decisiones: todo esto es también necesario. Pero en el caso de las largas épocas veraniegas, también se pueden aprovechar para afianzar lo aprendido y facilitar su recuperación. En este sentido, el repaso o la práctica repetida y espaciada son claves. Obviamente, revisar por completo el currículo correspondiente al curso recién acabado resulta inviable, no solo por las limitaciones temporales y de recursos, sino también porque ese no es el propósito de las vacaciones.
Entonces, ¿cómo podemos reducir el olvido de los aprendizajes escolares al tiempo que garantizamos el descanso de los niños y adolescentes durante las vacaciones de verano?
Mantener los aprendizajes sin renunciar al descanso
El periodo vacacional ofrece un entorno idóneo para el aprendizaje no formal basado en experiencias reales, alejadas del formato académico. En este sentido, los niños, niñas y adolescentes pueden:
Leer con libertad (explorando todo tipo de textos fuera del ámbito escolar).
Realizar actividades cotidianas (sobre todo, del ámbito doméstico como cocinar, donde toman decisiones, leen recetas y aplican cálculos matemáticos de forma práctica).
Practicar actividades deportivas (promoviendo tanto la actividad física como hábitos saludables).
Acudir a talleres de temáticas específicas de su elección (favoreciendo su autonomía y dando la oportunidad de aprender más allá de los contenidos escolares; por ejemplo, robótica).
Asistir a campamentos de verano (supone convivir con otros “iguales” y desarrollar habilidades sociales, además de fomentar la autonomía).
Jugar (combina la interacción social con el manejo de información, de manera que se trabajan la atención y la memoria).
Visitar museos (supone una manera de enriquecer el aprendizaje durante el curso escolar con experiencias reales, además de fomentar la curiosidad, entre otros aspectos).
Participar en programas educativos (especialmente para el alumnado con dificultades de aprendizaje o socialmente desfavorecido y dirigidos a reforzar áreas esenciales como la lectoescritura).
Si bien las vacaciones estivales son lo suficientemente largas para dedicar parte de ellas a continuar aprendiendo, no debemos olvidar que los periodos de descanso también son fundamentales para afianzar los aprendizajes. Estos meses pueden tomarse como una oportunidad para buscar un equilibrio entre periodos de reposo y la realización de actividades estimulantes para los más pequeños.
También es una ocasión ideal para dejar que los niños y adolescentes tomen la iniciativa y tengan la autonomía necesaria para seleccionar las actividades en las que quieran participar y organizar su horario durante estos meses.
El verano supone un entorno menos estructurado que el escolar, sin horarios rígidos ni planificación estricta de actividades. La sensación de tener demasiado tiempo en nuestras manos puede llevar a prácticas ociosas poco beneficiosas, como el abuso de pantallas o la disminución de la actividad física.
Dar opciones a los hijos e hijas para que sean partícipes de la gestión de su tiempo y preferencias es fundamental para garantizar que los resultados de las tareas de aprendizaje que se acuerden con ellos sean positivos. No es cuestión de hacer del hogar una segunda escuela, sino de adaptar las posibilidades de aprendizaje a las particularidades de la estación, dejando que las niñas y niños aprendan mientras se divierten. De esta manera, pueden disponer de más oportunidades reales para ejercer su autonomía.

Cuando llega el verano aparecen por todos lados supuestas “dietas milagro”, soluciones perfectas para perder esos kilos que nos sobran y nos impiden lucir un cuerpo perfecto. Y entre ellas encontramos las llamadas monodietas, regímenes restrictivos que consisten en consumir exclusivamente un solo tipo de alimento (o un grupo muy limitado de alimentos) durante un periodo determinado. El objetivo es perder peso rápidamente o “desintoxicar” el organismo.
Ejemplos populares son las dietas de la piña, de la manzana, de la sandía, del melocotón, de la alcachofa, algunas que incluyen cereales como la dieta del arroz, e incluso regímenes basados en la ingesta de alimentos proteicos como el atún o la leche. Su aparente simplicidad y la promesa de obtener resultados rápidos explican su éxito.
Una pérdida de peso efímera
Al tratarse de dietas que generan una drástica reducción calórica, se produce una pérdida de peso a corto plazo. Sin embargo, consumir una ingesta tan baja de calorías da lugar a una disminución de los niveles de glucosa en sangre, lo que activa mecanismos compensatorios para mantener el suministro de energía.
Inicialmente, el organismo utiliza el glucógeno hepático, principal fuente de reserva de glucosa que se encarga de mantener los niveles adecuados de este azúcar en sangre, especialmente entre comidas o durante el ayuno. Sin embargo, al agotarse ese depósito, el organismo comienza a movilizar masa muscular para obtener aminoácidos que, a través de otras rutas metabólicas, permiten la síntesis de glucosa. Este proceso, sostenido en el tiempo, puede llevar a una pérdida significativa de masa muscular y otras alteraciones metabólicas.
Por tanto, buena parte de la bajada de peso corresponde a una pérdida de agua y masa muscular, más que a grasa corporal, por lo que esos resultados tienden a ser temporales. Al finalizar este tipo de dietas, es común que el individuo recupere rápidamente el peso perdido cuando recupera su alimentación habitual, lo que se conoce como “efecto rebote”.
En suma, las monodietas pueden resultar atractivas por la obtención de resultados rápidos, pero no promueven una pérdida de peso mantenida en el tiempo ni educan en hábitos alimentarios saludables.
Pero ¿tienen algún beneficio real?
Más allá de la citada pérdida de peso inicial, las evidencias científicas que respalden beneficios reales y duraderos de las monodietas son prácticamente inexistentes. Algunos individuos reportan una “sensación de ligereza” o mejor digestión, pero estos efectos pueden deberse más a la eliminación de alimentos procesados que al régimen en sí.
También puede producirse el llamado “efecto placebo”: al creer que están siguiendo una dieta detox y están “limpiando” su cuerpo, las personas se sienten mejor, aunque no haya cambios fisiológicos demostrados.
¿Son peligrosas?
Sí, las monodietas pueden llegar a ser peligrosas, especialmente si se prolongan en el tiempo. Su principal riesgo es la deficiencia de nutrientes esenciales. Al consumir solo un tipo de alimento, dejamos de ingerir proteínas, grasas saludables, vitaminas y minerales necesarios para el correcto funcionamiento del organismo. Además, pueden dar lugar a problemas digestivos, trastornos metabólicos, problemas osteomusculares, alteraciones hormonales y desequilibrios electrolíticos, especialmente en personas con una situación de salud previa vulnerable.
Otro peligro importante es el de generar una relación poco saludable con la comida, marcada por la restricción y la culpa, que en casos extremos pueden desencadenar trastornos alimentarios como la ortorexia o la anorexia nerviosa.
Adicionalmente, esta limitación radical de nutrientes puede afectar el equilibrio de neurotransmisores a nivel cerebral, contribuyendo a una situación de irritabilidad y fatiga, afectando negativamente al bienestar emocional.
¿Por qué siguen siendo populares?
A pesar de los riesgos citados, las monodietas siguen teniendo éxito, especialmente en redes sociales y medios de comunicación. Su atractivo radica en la simplicidad y la promesa de resultados rápidos sin demasiado esfuerzo. Además, muchas de estas dietas son promovidas por celebridades o influencers, lo que les otorga una falsa credibilidad. La desinformación, la presión estética y la falta de educación nutricional en la sociedad también contribuyen a su seguimiento.
Debemos hacer hincapié en que las dietas de un solo alimento pueden ser eficaces para perder peso de forma rápida y temporal, pero no son efectivas a largo plazo y resultan peligrosas si el seguimiento de las mismas es prolongado. No aportan beneficios reales para la salud y pueden ocasionar deficiencias nutricionales e importantes problemas de salud.
Por estas razones, no son recomendables ni deben ser promovidas como métodos adecuados de control de peso o mejora de la salud. La mejor estrategia para lograr y mantener un peso saludable sigue siendo una alimentación equilibrada, variada y sostenida en el tiempo, acompañada de actividad física regular y hábitos de vida saludables.

The US president, Donald Trump, recently announced that Russia had 50 days to end its war in Ukraine. Otherwise it would face comprehensive secondary sanctions targeting countries that continued trading with Moscow.
On July 15, when describing new measures that would impose 100% tariffs on any country buying Russian exports, Trump warned: “They are very biting. They are very significant. And they are going to be very bad for the countries involved.”
Secondary sanctions do not just target Russia directly, they threaten to cut off access to US markets for any country maintaining trade relationships with Moscow. The economic consequences would affect global supply chains, targeting major economies like China and India that have become Russia’s commercial lifelines.
Despite the dire threats, Moscow’s stock exchange increased by 2.7% immediately following Trump’s announcement. The value of the Russian rouble also strengthened. On a global scale, oil markets appear to have relaxed, suggesting traders see no imminent risks.

This market reaction coincided with a nonplussed Moscow. While official statements noted that time was needed for Russia to “analyse what was said in Washington”, other statements suggested that the threats would have no effect. Former Russian president Dmitry Medvedev, for example, declared on social media that “Russia didn’t care” about Trump’s threats.
The positive market reaction and lack of panic from Russian officials tell us more than simple scepticism about Trump’s willingness to follow through.
If investors doubted Trump’s credibility, we would expect market indifference, not enthusiasm. Instead, the reaction suggests that financial markets expected a stronger response from the US. As Artyom Nikolayev, an analyst from Invest Era, quipped: “Trump performed below market expectations.”
A reprieve, not a threat
Trump’s threat isn’t just non-credible – the positive market reaction in Russia suggests it is a gift for Moscow. The 50-day ultimatum is seen not as a deadline but as a reprieve, meaning nearly two months of guaranteed inaction from the US.
This will allow Russia more time to press its military advantages in Ukraine without facing new economic pressure. Fifty days is also a long time in American politics, where other crises will almost certainly arise to distract attention from the war.
More importantly, Trump’s threat actively undermines more serious sanctions efforts that were gaining momentum in the US Congress. A bipartisan bill has been advancing a far more severe sanctions package, proposing secondary tariffs of up to 500% and, crucially, severely limiting the president’s ability to waive them.
By launching his own initiative, Trump seized control of the policy agenda. Once the ultimatum was issued, US Senate majority leader John Thune announced that any vote on the tougher sanctions bill would be delayed until after the 50-day period. This effectively pauses a more credible threat facing the Kremlin.
This episode highlights a problem for US attempts to use economic statecraft in international relations. Three factors have combined to undermine the credibility of Trump’s threats.
First, there is Trump’s own track record. Financial markets have become so accustomed to the administration announcing severe tariffs only to delay, water down or abandon them that the jibe “Taco”, short for “Trump always chickens out”, has gained traction in financial circles.
This reputation for failing to stick to threats means that adversaries and markets alike have learned to price in a high probability of backing down.
Second, the administration’s credibility is weakened by a lack of domestic political accountability. Research on democratic credibility in international relations emphasises how domestic constraints – what political scientists call “audience costs” – can paradoxically strengthen a country’s international commitments.
When leaders know they will face political punishment from voters or a legislature for backing down from a threat, their threats gain weight. Yet the general reluctance of Congress to constrain Trump undermines this logic. This signals to adversaries that threats can be made without consequence, eroding their effectiveness.
And third, effective economic coercion requires a robust diplomatic and bureaucratic apparatus to implement and enforce it. The systematic gutting of the State Department and the freezing of United States Agency for International Development (USAID) programmes eliminate the diplomatic infrastructure necessary for sustained economic pressure.
Effective sanctions require careful coordination with allies, which the Trump administration has undermined. In addition, effective economic coercion requires planning and credible commitment to enforcement, all of which are impossible without a professional diplomatic corps.
Investors and foreign governments appear to be betting that this combination of presidential inconsistency, a lack of domestic accountability, and a weakened diplomatic apparatus makes any threat more political theatre than genuine economic coercion. The rally in Russian markets was a clear signal that American economic threats are becoming less feared.

One of the first things to greet visitors at the V&A’s new Design and Disability exhibition is a striking blue bench by artist Finnegan Shannon titled, Do You Want Us Here Or Not? This exhibit is a response to the often inadequate seating in museums, which not only acts as a barrier to accessibility for many people, but is more widely symptomatic of ableist approaches to museum and exhibition design.
In this case, the invitation to “Please sit here!” sets the tone for the whole exhibition, which also includes a large sensory map of the layout (located at wheelchair level), a tactile map, and QR codes that link to audio description for blind and partially sighted visitors, and also British Sign Language interpretation.
Looking for something good? Cut through the noise with a carefully curated selection of the latest releases, live events and exhibitions, straight to your inbox every fortnight, on Fridays. Sign up here.
Aiming to showcase the radical contributions of disabled, deaf and neurodivergent people to design history and contemporary culture from the 1940s until the present, the exhibition goes well beyond this, addressing an impressively wide range of issues around access, disability and exclusion. It also reveals how ableism operates across a range of exclusions, such as race, gender, class and more.
As the introductory notes point out: “Disabled people past and present have challenged and confronted the imbalance of design in society. This exhibition highlights disabled individuals at the heart of design history … It is both a celebration and a call to action.”
While the fight for disability justice goes back many decades – also documented in the exhibition – it’s only relatively recently that questions of access and equality have gone beyond the physical. These include a wide range of issues related to neuro-inclusion and sensory access, including calm spaces and sensory maps that indicate noisy areas.
My own interest in sound in museums has come partly out of research focusing on the role of acoustics in creating accessible spaces, and from my own experience of noise sensitivity conditions hyperacusis and misophonia. Inclusive sonic design seeks to address how sound operates as a factor of social inclusion and exclusion in places like museums.
The V&A exhibition comprises three sections: visibility, tools and living. Visibility focuses on design and art as fundamental tools of activism and includes work created as part of disability justice movements over many decades. This section is a stark reminder of the justice and rights that only come about through extensive struggles.
Tools highlight the extraordinary contribution to design innovation made by disabled people. Living explores stories of disabled people claiming space and imagining the worlds that they want to live in.
Sections two and three both advocate for the social model of disability in which people are rendered disabled by their environment, something that calls for design solutions (as opposed to the medical model in which people are required to navigate and find solutions to their “problem”).
The exhibition draws attention to a wide range of physical and sensory exclusions, both in the displays and the design of the space itself. The in-house design team includes staff with personal experience of disability who also worked closely with external partners living with disability.
There are plenty of exhibits that can be experienced through touch. For partially sighted visitors, there are strong visual contrasts in the wall colours and the edges of displays are lit up. And there are raised edgings on all exhibits for people using a cane – all of which help with navigation.
There are also quiet areas and plenty of seating. Some of these features are already being incorporated into gallery and exhibition design, and hopefully will soon become standard.
I particularly liked the way various issues intersect in the exhibition, in which a range of exclusions are set alongside one another: race, hearing impairment, youth exclusion and stammering, for example.
Other favourites included the B1 Blue Flame rattling football used for blind football, which visitors can pick up, feel, smell, shake and listen to. The Deaf Rave set and Woojer Vest are designed for deaf clubbers and performers and use vibrating tactile discs that amplify sound vibrations.
The beautiful blanket and pillow entitled Public S/Pacing by Helen Statford offers an invitation to rest, drawing attention to “crip time”, accepting “a different pace to non-disabled norms, challenging conventions of productivity, and resting in radical ways that would actually benefit society at large”.
The blanket highlights the failures of the design of public spaces to include disabled people, “challenging ableist assumptions with care and visibility”. The reverse of the blanket has a quotation from Rhiannon Armstrong’s Radical Act of Stopping (2016), embroidered by Poppy Nash.
The exhibition includes many examples of “disability gain” by which design aimed at a particular group of people unintentionally benefits others, too. An example is the smartphone touchscreen, based on technology developed by engineers Wayne Westerman and John Elias as an alternative to the standard keyboard, which Westerman was unable to use due to severe hand pain.
Initially marketed to people with hand disabilities, the technology was later sold to Apple where it revolutionised mobile phone technology.
The final panel of the exhibition is titled Label for Missing Objects, an imaginative and fitting way to mark the continuing story of designing a world that works for “every body and every mind”.
Design and Disability is a rich, thought-provoking and landmark exhibition. Kudos to the V&A, although its importance is so obvious, I wonder why it took this long to host a show dedicated to disabled artists and designers and the wider social impact of their work.
I very much hope there are plans for the exhibition to tour the UK and beyond, and to become a permanent gallery at the V&A, so that it can inform curation and design work in other museums.
Design and Disability at the V&A runs until February 15 2026.

UK chancellor Rachel Reeves would like Britons to invest more in stocks – particularly UK stocks – rather than keep their money in cash. She has even urged the UK finance industry to be less negative about investing and highlight the potential gains as well as the risks.
Stock ownership is important for governments for a variety of reasons. Boosting capital markets can encourage business expansion, job creation and long-term economic growth. It can also give people another source of income in later life, especially as long-term investing can offer greater returns than saving.
But in the UK, excluding workplace pensions, only 23% of people have invested in the stock market, compared to nearly two-thirds in the US. Survey results suggest that American consumers are generally more comfortable with financial risks.

And it appears that a greater degree of risk translates into closer political engagement. During market shocks driven by US president Donald Trump’s tariff chaos, many Americans tracked headlines – and their portfolios – closely. This contrasts with the UK, where most people keep their savings in safer assets like cash savings accounts or premium bonds.
If Britons are more risk-averse, media coverage that tends to be noisier when markets fall than when they recover may be having an impact. While concerns regarding market volatility may be valid, they can overshadow the long-term benefits of investing.
One key opportunity that many British consumers have missed out on is the rise of low-cost, diversified exchange-traded funds (ETFs), which have made investing more accessible and affordable. An ETF allows investors to buy or sell baskets of shares on an exchange. For example, a FTSE100 ETF gives investors exposure to the UK’s top 100 companies without having to buy each one individually.
This is exactly the kind of long-term, low-cost investing that Reeves appears to be promoting. But should savers be worried about current market volatility – much of it driven by trade tensions and tariff uncertainty? One view, of course, is that volatility is simply part of investing.
But it could also be argued that big shifts within the space of a single month are often exaggerated. People are also likely to be put off by news headlines, which tend to exaggerate the swings in the market.
Examining daily excess returns in the US stock market from November 2024 to April 2025, I plotted cumulative returns (which show how an investment grows over time by adding up past returns) within each month. April 2025 stands out. Despite experiencing several sharp daily losses, the market rebounded swiftly in the days that followed.
This pattern isn’t new. Historically, markets have shown a remarkable ability to recover from short-term shocks. Yet many potential investors could be deterred by alarming headlines that, while factually accurate, often highlight single-day declines without broader context.
The reality is that the stock market is frequently a series of short-lived storms. These are volatile, yes, but often followed by calm and recovery.
Fear and caution
During market downturns, it’s common for people to try to understand why this time is worse or analyse if this crash is more serious than previous ones.
The fear these headlines generate could feed into barriers to long-term investing in the UK. And that’s one of the challenges the chancellor faces in encouraging more Britons to invest.
For those already invested in the stock market, short-term declines are part of the journey. They are risks that can be borne with the understanding that markets tend to recover over time.
My analysis of daily US stock market data since 1926 shows that after sharp daily drops, the market often rebounds quickly (see pie chart below). In fact, more than a quarter of recoveries occur within just a few days.
But this resilience is rarely the focus of media coverage. It’s far more common to see headlines reporting that the market is down than to see follow-ups highlighting how quickly it bounced back.
Research has shown that negative economic information is likely to have a greater impact on public attitudes. For example, a sharp drop in the stock market might dominate front pages, while a steady recovery over the following weeks barely gets a mention. The imbalance reinforces a sense of crisis, even when the broader picture is less bleak.
Markets went on to recover in April 2025… but did the headlines reflect this? David G40/Shutterstock
Unbalanced reporting can distort perceptions, discouraging potential investors who might otherwise benefit from long-term participation in the market. It appears that American perceptions of their finances are also affected by news coverage in a similar way.
Over the long term, the difference between stock market returns and the generally lower returns from government bonds is known as the “equity risk premium puzzle”. Economists have long debated why this gap is so large. Some observers argue it may narrow in the future. But many others, including the chancellor, believe that investing in the stock market remains a beneficial long-term strategy.
If more people are to benefit from long-term investing, it’s vital to tell the full story. That means not just highlighting when markets fall, but following up on how they recover afterwards.

Gloomy economic figures have heaped more pressure on the British government and its promise to improve growth. And if that wasn’t enough, there have also been some stark warnings about public finances and the country’s ability to service its debts.
All of this has led to a growing expectation that the UK chancellor Rachel Reeves will have to bring in some significant tax hikes later this year, or reduce government spending.
But both of these options could worsen the long-term economic outlook, by further constraining GDP growth. That was precisely the fate of governments that pursued an agenda of “austerity” – cuts in spending and higher taxes – to tackle the expanded public debt after the financial crisis of 2008.
It was a strategy that ultimately led to higher public debt. Put simply, when governments spend less, GDP tends to fall. And when GDP falls and a country is less productive, tax revenues go down too.

To make things even more complicated for the chancellor, the UK government has also widened its debt risk by changing its fiscal rules to acknowledge extra financial responsibilities.
This adjustment gave the government more financial assets, including student loans and public pension holdings. But it also meant taking on more liabilities, including the pension schemes it would have to bail out if necessary.
In July 2025, the Office for Budget Responsibility (OBR) identified several other sectors – including universities, housing associations and water companies – whose large debts could become government liabilities in the future.
A bigger balance sheet automatically means more public financial risk. And climate change further raises these risks, the OBR says, by forcing the government to spend more on dealing with environmental damage and eroding fossil-fuel taxes, which still raise around £24 billion for the Treasury.
The OBR is also concerned about the rising cost of pensions for an ageing population. In fact, the UK’s system is not particularly expensive, partly due to its reliance on private pensions (funded by employers and employees).
Yet this reliance brings a different kind of government cost. For these private sector schemes have attempted to insulate themselves against the strains of an ageing population, as more employees retire than join the workforce (and as retirees live longer).
Often this has involved shifting from “defined benefit” plans, which guarantee retirement income, to “defined contribution” plans, where payouts depend on how much members pay in and how well funds are invested.
But that shift has also made it harder for the government to borrow the money it needs for public spending.
Defined benefit funds, seeking a steady long-term return, used to be big buyers of UK government bonds (gilts) – the financial assets that the government sells to raise money. In contrast, defined contribution funds invest mainly in equities (company shares), which promise a higher return on investment that can grow pension pots faster.
UK industrial policy supports this shift from gilts to other assets. It wants pension funds to invest in innovation and infrastructure as a way of stimulating its often mentioned mission of economic growth.
The growth gamble
Yet the move by pensions towards equities is steadily deflating demand for new government bonds. This then forces the government to pay higher interest rates to attract enough buyers, often from overseas.
There is also pressure on the government to relax the “triple lock” on state pensions. This pledge – to raise the basic state pension by at least 2.5% every year, and maintained by all parties since 2011 – is costing around three times as much as was projected at launch, despite fewer pensioners escaping poverty since it was introduced.
Overall, inflation and an ageing population have lifted state spending on pensions to around 5% of GDP.
These pressures all strengthen the view that the government will need another tax-raising budget this year. How else will it pay for its plans for spending on healthcare, housing, infrastructure and defence?
Hopes that a faster-growing economy would narrow the deficit, by boosting tax receipts and reducing spending requirements, have not been fulfilled.
Yet calls for significant tax increases – which could dampen growth – may still be be resisted.
Under pressure, she may well consider a compromise like a “wealth tax” targeting the richest, that would also satisfy the Labour left. Yet the only way to really raise significant extra funds is to increase income tax, VAT or national insurance, which would be extremely risky politically.
But all economic policy comes with risk. And she may end up sticking with her position and putting her (taxpayers’) money on the hope that today’s deficit will eventually be narrowed by faster growth. Relying on more investment to solve economic problems depends on investors trusting the economic stability of the UK, which is a gamble. But it is a gamble the government may still be willing to take.

From your phone to your sponge, your toothbrush to your trolley handle, invisible armies of bacteria are lurking on the everyday objects you touch the most. Most of these microbes are harmless – some even helpful – but under the right conditions, a few can make you seriously ill.
But here’s the catch: some of the dirtiest items in your life are the ones you might least expect.
Here are some of the hidden bacteria magnets in your daily routine, and how simple hygiene tweaks can protect you from infection.

Shopping trolley handles
Shopping trolleys are handled by dozens of people each day, yet they’re rarely sanitised. That makes the handles a prime spot for germs, particularly the kind that spread illness.
One study in the US found that over 70% of shopping carts were contaminated with coliform bacteria, a group that includes strains like E. coli, often linked to faecal contamination. Another study found Klebsiella pneumoniae, Citrobacter freundii and Pseudomonas species on trolleys.
Protect yourself: Always sanitise trolley handles before use, especially since you’ll probably be handling food, your phone or touching your face.
Kitchen sponges
That sponge by your sink? It could be one of the dirtiest items in your home. Sponges are porous, damp and often come into contact with food: ideal conditions for bacteria to thrive.
After just two weeks, a sponge can harbour millions of bacteria, including coliforms linked to faecal contamination, according to the NSF Household Germ Study and research on faecal coliforms.
Protect yourself: Disinfect your sponge weekly by microwaving it, soaking it in vinegar, or running it through the dishwasher. Replace it if it smells – even after cleaning. Use different sponges for different tasks (for example, one for dishes, another for cleaning up after raw meat).
Chopping boards
Chopping boards can trap bacteria in grooves left by knife cuts. Salmonella and E. coli can survive for hours on dry surfaces and pose a risk if boards aren’t cleaned properly.
Protect yourself: Use separate boards for raw meat and vegetables. Wash thoroughly with hot, soapy water, rinse well and dry completely. Replace boards that develop deep grooves.
Tea towels
Reusable kitchen towels quickly become germ magnets. You use them to dry hands, wipe surfaces and clean up spills – often without washing them often enough.
Research shows that E. coli and salmonella can live on cloth towels for hours.
Protect yourself: Use paper towels when possible, or separate cloth towels for different jobs. Wash towels regularly in hot water with bleach or disinfectant.
Mobile phones
Phones go everywhere with us – including bathrooms – and we touch them constantly. Their warmth and frequent handling make them ideal for bacterial contamination.
Research shows phones can carry harmful bacteria, including Staphylococcus aureus.
Protect yourself: Avoid using your phone in bathrooms and wash your hands often. Clean it with a slightly damp microfibre cloth and mild soap. Avoid harsh chemicals or direct sprays.
Protect yourself: Store your toothbrush as far from the toilet as possible. Rinse it after each use, let it air-dry upright and replace it every three months – or sooner if worn.
Bathmats
Cloth bathmats absorb water after every shower, creating a warm, damp environment where bacteria and fungi can thrive.
Protect yourself: Hang your bathmat to dry after each use and wash it weekly in hot water. For a more hygienic option, consider switching to a wooden mat or a bath stone: a mat made from diatomaceous earth, which dries quickly and reduces microbial growth by eliminating lingering moisture.
Pet towels and toys
Pet towels and toys stay damp and come into contact with saliva, fur, urine and outdoor bacteria. According to the US national public health agency, the Centers for Disease Control and Prevention, pet toys can harbour E. coli, Staphylococcus aureus and Pseudomonas aeruginosa.
Protect your pet (and yourself): Wash pet towels weekly with hot water and pet-safe detergent. Let toys air dry or use a dryer. Replace worn or damaged toys regularly.
Protect yourself: Bring your own tools to salons or ask how theirs are sterilised. Reputable salons will gladly explain their hygiene practices.
Airport security trays
Airport trays are handled by hundreds of people daily – and rarely cleaned. Research has found high levels of bacteria, including E. coli.
Protect yourself: After security, wash your hands or use sanitiser, especially before eating or touching your face.
Hotel TV remotes
Studies show hotel remote controls can be dirtier than toilet seats. They’re touched by many hands and rarely sanitised.
Common bacteria include E. coli, enterococcus and Staphylococcus aureus, including MRSA, according to research.
Protect yourself: Wipe the remote with antibacterial wipes when you arrive. Some travellers even put it in a plastic bag. Always wash your hands after using shared items.
Bacteria are everywhere, including on the items you use every day. You can’t avoid all germs, and most won’t make you sick. But with a few good habits, such as regular hand washing, cleaning and smart storage, you can help protect yourself and others.

The report is from Community Living Ontario, a non-profit organization that advocates for people who have an intellectual disability. It analyzes the results from a survey of 541 caregivers of students with disabilities about their experiences in Ontario schools.
Seclusion rooms are spaces where students can be kept in isolation and are not permitted to leave. Respondents to the Crisis in the Classroom report detailed incidents such as a student being secluded in a padded room, and a student being isolated in a small, closet-sized room.
While some school boards have developed guidance independently, there is currently no provincial policy on the use of seclusion rooms in Ontario. The Crisis in the Classroom report calls for clear and enforceable provincial regulations and policy around seclusion and restraint.
As an assistant professor of childhood and youth studies whose work examines constructions of the “problem child” and everyday injustices against disabled and racialized children, I believe it is critical for Ontario residents and policymakers to take stock of the negative effects of seclusion rooms and commit to alternatives.
I am unaffiliated with this report, but earlier in my career, I worked as as a one-on-one educational aide for students who attended a special education school that used seclusion.
Defining seclusion rooms
As education researchers Nadine Alice Bartlett and Taylor Floyd Ellis show, there is inconsistent terminology used to describe seclusion in schools, meaning that “the conditions under which such practices may be used in some instances are subjective,” and this “may contribute to a broad interpretation of what is deemed acceptable … in schools.”
As opposed to sensory rooms, which students can usually leave at will and are often designed with sensory tools available for self-regulation (like weighted toys), seclusion rooms serve to isolate or contain students.
In the Crisis in the Classroom report, 155 survey respondents said seclusion was used on their child in the 2022-23 school year, where seclusion means having a locked/blocked door (83 respondents) or being physically prevented from leaving (25 respondents).
Regular, sustained seclusion
Crisis in the Classroom notes that almost half of the students who had experienced seclusion were secluded on a regular basis, and more than 10 per cent were secluded for longer than three hours.
Research shows thatseclusion is often discriminatory along lines of race, class and ability. Reflecting these patterns identified in larger research, the report flags that students had a higher risk for being secluded if they came from households with lower parental education and income levels, and if they were labelled with a behavioural identification or a mild intellectual disability.
More than half of the caregivers surveyed had never given permission for their children to be secluded, and the report includes quotes from caregivers who were never told it was happening.
Response to perceived source of school violence
Seclusion rooms are commonly justified as necessary tools to keep teachers and (other) students safe.
I argue that turning to these alternatives, as the report recommends, is of dire importance. Investigations elsewhererepeatedly find that seclusion rooms are most frequently used for discipline or punishment — not for safety.
With adequate staffing and trauma-informed training, some schools have reduced or eliminated seclusion. (CDC/Unsplash)
This appears in the physical harm (for students and staff) that can occur in the physical restraints often required to force a student into a seclusion room. It also appears in the trauma that can ensue from seclusion (for students and staff) that increases the likelihood of future physical confrontations.
As the Crisis in the Classroom report and repeated exposés illustrate, a lack of policy does not mean seclusion isn’t happening in Ontario. It means seclusion is happening without provincial policy to regulate things like:
Which students can or cannot be secluded, for how long and how often;
What rooms for seclusion must look like and essential safety features;
What data staff must collect about why seclusion rooms are used;
When caregivers must be notified.
Without these guidelines, sometimes no one knows that seclusion is happening — much less in what spaces, for which students and why — beyond the students and school staff who may be traumatized by this practice.
Reports of violence in schools
Crisis in the Classroom notes that teachers’ unions have reported there’s been an increase in violence by students against teachers, often presented in a way that suggests that disabled students are a primary source of this violence. The report acknowledges that the Elementary Teachers’ Federation of Ontario has said that students with special education needs have been “chronically under-served by the government.”
News media coverage, the report suggests, “often takes the side of educational staff, and has an unfortunate habit of conflating disability with aggressive behaviour.”
The report points to the dire need to eliminate seclusion and turn towards possibilities that do not increase violence in schools and target disabled students.
The report’s recommendations echo calls from teachers’ unions for appropriate, adequate staffing in schools and increased professional development, especially trauma-informed training, that would support teachers’ work delivering supportive and inclusive education that keeps everyone safe.
And these recommendations make an urgent call for strong and clear policy on seclusion and restraint in Ontario that would severely limit it or eliminate it entirely — and at least track when it’s occurring.
Safer and more humane schools
This devastating report illustrates that we need policy on seclusion in Ontario now to protect everyone in our schools.
More humane practices will keep schools safer for everyone, including teachers and all students, especially students who are still being subjected to seclusion today.

Au-delà de la confrontation militaire, la guerre en Ukraine se déploie dans le domaine numérique et dans l’espace informationnel. Une véritable guerre cognitive est en cours.
Dans le même temps, la Russie ne néglige pas le théâtre national : le premier adjoint du chef de l’administration présidentielle, Sergueï Kirienko, a mis en place le projet dit des « Architectes sociaux », qui lui permet de disposer d’un réseau de technologues politiques à travers toute la Fédération de Russie.
Au niveau international, l’ingérence russe est un outil de conflictualité qui, parce qu’elle cible les prises de décision et les perceptions humaines, est mobilisée au travers de la guerre cognitive qui sert ici les objectifs de guerre russes. L’importance de la guerre cognitive est telle que les Occidentaux qui travaillent à définir des doctrines sur ce sujet.
Si l’on analyse beaucoup les mouvements sur la ligne de front, on souligne moins le fait que, par sa résistance à Moscou, l’Ukraine montre au reste du monde qu’il est possible de s’opposer avec vigueur aux visées du Kremlin, ce qui nuit à l’image d’invincibilité que le Kremlin cherche à projeter. Cette résistance pourrait se résumer en un mot ukrainien : « воля » (volia) qui a le double sens de « volonté » et de « liberté ».
Les attaques informationnelles russes : formater la pensée et bloquer la capacité de décision
On a ainsi pu voir la Russie s’adapter à différentes plates-formes et, notamment, suivre les internautes des unes vers les autres, notamment lors de la migration de nombreux utilisateurs de X vers Bluesky. Les spécialistes russes ont aussi su adopter les nouvelles techniques permises par l’IA, notamment en produisant des deepfakes (ou hypertrucages) très réalistes, ainsi que de nombreux textes destinés à être relayés sur les réseaux sociaux, y compris des contrefaçons d’articles parus sur des sites occidentaux.
Les IA génératives ont également été infiltrées et peuvent, suite à une massification des contenus de désinformation russes incorporés à leurs bases de données, diffuser de la désinformation.
Cette débauche de moyens, dont le coût financier a singulièrement baissé avec le développement de la technologie, a plusieurs finalités qui se regroupent en un objectif général : d’une part, déployer une stratégie du chaos impactant directement le libre arbitre en général ; et, d’autre part, influencer la perception des décideurs afin, selon les cas, qu’ils hésitent à s’opposer aux objectifs du Kremlin ou qu’ils soient confortés dans leur volonté de les soutenir.
Dès lors, ce qui pourra permettre un maintien du libre arbitre et sa manifestation lors des processus électoraux par des votes ne s’alignant pas avec les candidats favorables à Moscou sera un obstacle à la finalité d’influence poursuivie par la Russie. Ce type de tentative d’ingérence a pu être observée à de multiples reprises, même si cela ne doit pas cacher l’existence de votants sensibles aux programmes portés par des partis radicaux pouvant être alignés avec l’approche idéologique du Kremlin.
La stratégie russe ne se contente pas de faire passer des contenus partiellement ou totalement faux pour vrais ; elle instrumentalise également des informations avérées de façon à les présenter sous un jour favorable aux intérêts russes, avant de noyer ses cibles sous une masse d’informations dont il devient difficile de trier le vrai du faux. Résultat : on a pu passer d’une étape visant à faire croire du vrai à une seconde visant à pousser les cibles à ne plus croire en rien.
L’approche informationnelle russe se déploie également sur plusieurs lignes temporelles : elle peut être extrêmement opportuniste et se saisir d’un événement sensible ou clivant pour un groupe social donné, faisant de la Russie un sujet de préoccupation constant pour les services de renseignement, notamment intérieurs. Par ailleurs, en usant d’agents jetables, la Fédération continue de semer le trouble par exemple en participant à faire croire à une montée de dégradations de véhicules commises par des militants écologistes pour attiser le sentiment anti-Verts en Allemagne, mais elle peut aussi travailler sur le temps long pour influencer en profondeur les perceptions du monde des individus et des groupes.
Maintenir la pression sur les élections
Les séquences électorales font l’objet d’une attention particulière de la machine informationnelle russe, qu’il s’agisse de truquer directement les résultats ou de procéder, durant les campagnes, à des ingérences visant à influencer les votes. Ces pratiques sont bien connues, même si elles ne sont pas toujours contrecarrées.
Ces « pseudo-observateurs » sont recrutés dans différents pays, y compris des États membres de l’UE. En ce sens, ils profitent de la légitimité accordée par le grand public à ces missions d’observation électorale souvent mal connues. Ces organisations de fausses observations électorales ont notamment pu être observées en Géorgie pendant les législatives de 2024.
« Volia » : un concept à l’opposé de l’influence russe
C’est ici que l’Ukraine prend une importance capitale dans la guerre informationnelle. Le pays a fait le choix d’adhérer à un modèle de société européen, dépeint par Moscou comme « décadent » en comparaison du sien – lequel est supposé protéger les « valeurs traditionnelles », mais aussi incarner l’ordre, à l’opposé du chaos qui serait la marque de fabrique des Européens. L’Ukraine paie le prix du sang, depuis maintenant plus de trois ans, pour avoir refusé d’adhérer au monde russe « Russkyi Mir », concept polymorphe qui se décline en des dimensions géopolitique, idéologique et sociétale.
Aux yeux de Moscou, remettre l’Ukraine au pas permettrait de prouver la supériorité du modèle russe. La russification opérée dans les territoires occupés a pour finalité de donner l’impression que ces populations sont heureuses de faire partie de la Russie et donc d’adhérer à ce même modèle. Ce supposé engouement serait la preuve de l’attrait du modèle social russe et soutiendrait la proposition selon laquelle Moscou peut représenter une alternative crédible au modèle occidental dans son ensemble. Devenir une alternative crédible permet à Moscou de prendre du poids au niveau international et de remettre en cause les règles de droit international qu’elle ne respecte pas et qu’elle aimerait voir changer, notamment au sein des instances internationales.
L’Ukraine pose un problème de nature ontologique, si l’on s’attache à une approche conceptuelle de l’ingérence russe. Ce problème se résume en un petit mot, « volia ». En ukrainien, ce mot à un double sens. Il signifie tout à la fois « volonté » et « liberté », la volonté ne pouvant s’entendre que comme libre, ne nécessitant pas de le préciser comme dans la notion de libre arbitre. Ce concept vient en opposition à la volonté de maîtrise et d’influence russe sur l’Ukraine.
La volonté russe de nier l’existence de l’Ukraine répond donc à des considérations multiples : imposer un choix de société que l’on présentera aux opinions des pays africains mais aussi du Moyen-Orient comme étant plus séduisant que le modèle occidental et européen ; participer à changer les règles du droit international ; et réaliser une projection de puissance en s’appuyant sur la force militaire, ce qui permettra de faire oublier que la Russie aura buté sur l’invasion de l’Ukraine pendant – au moins – plus de trois ans.
Une guerre cognitive
Le terme de « guerre hybride », bien que faisant débat dans la communauté académique, a été largement utilisé depuis le début de la guerre dans le Donbass en 2014. Ce concept s’appuie notamment sur des écrits de Franck Hoffman, datant de 2007, qui décrivaient alors les méthodes employées par Israël lors de la guerre du Liban en 2006.
Plus récemment, la notion de « guerre cognitive » a refait surface pour décrire les nouvelles modalités de la conflictualité moderne, mêlant guerre traditionnelle et actions informationnelles mais aussi économiques visant à affaiblir un adversaire pendant, et même avant le déclenchement de l’affrontement cinétique – ce qui ne va pas sans rappeler le fameux Art de la guerre, de Sun Tzu, qui affirmait qu’il était possible de gagner le combat avant même de le mener.
Là encore, le concept de guerre cognitive a fait l’objet de multiples débats. Au cours des années, il a été employé pour désigner divers types d’actions, incluant aussi bien les opérations psychologiques, ou PsyOps renommées Military Information Support Operations (MISO) à l’Ouest, quand on parlait plus volontiers de mesures actives à l’Est, ces dernières s’appuyant sur la fameuse Maskirovka, c’est-à-dire l’art de la duperie russe, puis sur les théories du contrôle réflexif.
In fine, on parle en Russie de « guerre non linéaire » qui consiste à mêler moyens miliaires et non militaires pour atteindre les objectifs. Lors d’un discours prononcé devant l’Académie des sciences militaires en 2019, Sergueï Choïgou, alors ministre de la défense, affirmera même la primauté des mesures non militaires sur la puissance militaire.
La guerre cognitive reste un concept flou pour les Occidentaux, qui le définissent, au sein de l’Otan, comme « des activités menées en synchronisation avec d’autres instruments de puissance, afin d’influer sur les attitudes et les comportements, en influençant, en protégeant ou en perturbant la cognition d’un individu, d’un groupe ou d’une population, afin d’obtenir un avantage sur un adversaire ».
La Russie semble le comprendre de manière encore globale et ontologique : ses opérations informationnelles visent différents niveaux de la société (allant de l’individu aux différents types de groupes), mais également différents niveaux d’activité humaine (économiques, politiques, sociétaux, culturels, etc.).
L’exemple des étoiles de David peintes sur les murs de Paris peu après les attaques du 7 octobre 2023 par des ressortissants moldaves engagés par les services russes en fournit une bonne illustration. Ces agents sont qualifiés de « jetables » car ils sont recrutés et payés pour l’occasion afin de réaliser des actions simples dans le monde physique en n’ayant que peu, voire pas, d’attache avec le Kremlin. Cette action était ensuite facile à utiliser dans la sphère informationnelle et à amplifier numériquement. De plus, des personnes de bonne foi pouvaient observer ces graffitis, bien réels, ce qui donnait une crédibilité et une existence à une action pourtant créée de toutes pièces afin de déstabiliser la société française.
La guerre cognitive est aujourd’hui un concept encore en cours de définition. Si elle implique l’usage de stratégies destinées à mener des attaques sur les cognitions humaines, elle ne peut cependant se limiter à cette approche. Elle doit être pensée dans une perspective plus vaste, d’ordre ontologique. Cela suppose de prendre en compte les domaines dans lesquels ses actions peuvent se déployer, et les fondements sur lesquels elle s’appuie. L’objectif de ces actions est de perturber, de détourner, voire de tordre la prise de décision – un processus qui, par essence, devrait rester libre, comme le suggère le terme « volia ».
