Iran fired two ballistic missiles on March 20, 2026, at the Indian Ocean island of Diego Garcia, which hosts a strategically important joint U.S.-U.K. military base, according to U.S., U.K. and Israeli officials. One missile broke apart during flight, and the other appears to have been destroyed by U.S. missile defenses.

Iran has denied responsibility for the launches.

Diego Garcia is about 2,500 miles (4,000 kilometers) from Iran, which is about twice as far as the top range Iran has declared that its ballistic missiles have. Parts of Western Europe, Asia and Africa lie within a 2,500-mile (4,000-km) radius of Iran, raising concerns about the vulnerability of these areas.

However, there’s no evidence that Iran has developed a new type of missile or that it can otherwise hit targets at the longer range. Iran most likely modified an existing type of missile, but increasing a missile’s range poses significant challenges.

Ballistic missile basics

A ballistic missile is launched on a rocket and, after separating from it, subsequently flies mostly under the influence of gravity to its destination. The name refers to the characteristic arc of projectiles whose trajectories are largely shaped by gravity. The range of these missiles is determined by the size of the rocket.

Short-range ballistic missiles can fly about 300 to 600 miles (500 to 1,000 km) and can be launched from mobile trucks. They are used for destroying key defensive infrastructure such as radars.

Medium-range ballistic missiles have ranges of about 600 to 1,800 miles (1,000 to 3,000 km). They are used to attack more strategic targets such as command and control centers where military leaders coordinate operations. Intermediate-range ballistic missiles operate over about 1,800 to 3,400 miles (3,000 to 5,500 km), putting much larger geographical regions at risk.

Intercontinental ballistic missiles, or ICBMs, have a range of about 3,100 to 6,200 miles (5,000 to 10,000 km), making it possible to strike targets over an enormous area. These very long-range weapons require multiple rocket stages. They fly very high, exiting the atmosphere and entering into space, before arcing back toward Earth.

At the height of the Cold War, both the Soviet Union and the United States had thousands of ICBMs armed with nuclear warheads aimed at each other. Each weapon could obliterate an entire city, and nuclear-armed ICBMs have been the basis of mutually assured destruction in which both sides were deterred from ever using the missiles.

Iran’s inventory

Iran has an extensive ballistic missile program. The country has been developing a number of short-range ballistic missiles for many years. The suite of weapons includes the Fateh, Shahab-2 and Zolfaghar systems.

The ranges of these missiles – up to 500 miles (800 km) – are insufficient for Iran to use them against Israel directly because the closest distance between the two countries is about 550 miles (900 km). However, Iranian-backed militias have deployed these weapons in neighboring countries, such as Lebanon and Syria, and have launched them from there in attacks against Israel.

Iran has also developed intermediate-range ballistic missiles such as the Shahab-3, Sejjil and Khorramshahr weapons. These missiles have ranges of up to 1,250 miles (2,000 km), which means they can reach Israel directly from Iran.

Harder to go farther

Scaling up from short range to medium range to intermediate requires larger and larger rockets, which presents a number of increasingly difficult technical challenges. Larger rockets create more dynamic vibrations that the missile structure and all its components must survive. This requires an advanced manufacturing and testing infrastructure.

The size of the rocket also determines how much payload the missile can deliver. This challenge is very well-illustrated by the enormous Saturn V rocket that took astronauts to the Moon. Of the total launch mass, less than 2% was delivered to the lunar surface, with propellant taking up almost all the remaining mass.

ICBMs also have a small payload mass, and this in part explains why militaries more often load them with nuclear warheads than conventional chemical explosives. Pound for pound, nuclear warheads produce much larger effects. It is usually not worth the very high cost of sending an ICBM many thousands of miles just to blow up a single building.

Finally, maintaining control of the missile and hitting a target with sufficient accuracy becomes increasingly more difficult as range is extended. Missile navigation systems based on gyroscopes have slight errors that increase with time, and GPS-guided missiles can be jammed.

Limits on Iran’s reach

Having successfully launched satellites into space using two-stage rockets, however, perhaps it is not too surprising that Iran has been able to build on those successes to achieve longer ranges for its missiles. The simplest modification to extend a missile’s range is to reduce its payload.

Iran has reportedly demonstrated this with the Khorramshahr, using a smaller warhead that gives it a range of 1,800 miles (3,000 km). Some observers suggest that the missiles Iran fired at Diego Garcia most likely were further-modified Khorramshahrs.

In the Iranian attack on Diego Garcia, however, one of the missiles failed in flight and the other appeared to have been destroyed by U.S. defenses. The missile failure may indicate that Iran is attempting to operate these systems at distances they are not reliably capable of.

The apparent ability of the U.S. to defend against the second missile suggests that the Iranian intermediate range ballistic missiles do not pose a significant military threat. This conclusion is further supported by the earlier high-volume attack by Iran in December 2025 when it launched hundreds of missiles and drones in a concerted raid against Israel. Almost all were shot down by a combination of Israeli and U.S. defenses.

Surprising but not so threatening

Ultimately, while Iran’s long-range attack on Diego Garcia caught the world off guard, it was likely intended more for its psychological and political effects than for posing a real military threat.

It is worth noting that an additional challenge with fielding intermediate-range ballistic missiles is the cost, which scales with the size of the rocket required. A two-stage rocket that can fly 2,500 miles (4,000 km) is probably one of the most expensive weapons that Iran possesses: It is therefore unlikely to have many of them. When launched in small salvos, these missiles are highly susceptible to the sophisticated air defense systems of the U.S. and its allies.

Still, the attack has certainly gotten the attention of the world and may increase pressure for diplomatic approaches to end the conflict with Iran quickly.

When everyday tasks become harder: Early clues to Alzheimer’s disease

Source: The Conversation – Canada – By Maryam Ghahremani, Research Data Scientist at Hotchkiss Brain Institute, University of Calgary

While almost everyone misplaces keys or forgets a name from time to time, chronic struggles that linger or worsen over months and years may reveal early disruptions in the brain’s ability to co-ordinate complex tasks. (Freepik)

For many older adults, life is full of routines. Making breakfast, paying bills, shopping, driving, managing appointments and keeping track of medications are tasks done almost automatically. For most, these routines run smoothly, but for some, small disruptions begin to creep in.

These small struggles matter. Perhaps it starts with uncharacteristically forgetting to add an item to the grocery list or misplacing a pair of glasses. Maybe a chequebook gets mismanaged, or a favourite recipe becomes harder to follow.

These moments can be brushed off as part of aging or blamed on a busy mind. Yet, when these new difficulties persist over time, they may be more than just minor frustrations; they might be early signs of something far deeper.

Understanding functional changes

Daily functioning is a key measure of independence, reflecting not only memory, but the co-ordination, planning and attention required to navigate everyday life. Changes here are often subtle, and they can go unnoticed by family members or health-care providers.

Clinicians have long recognized that loss of functional independence, like difficulty performing everyday activities, is a hallmark of dementia. It is, in fact, part of the formal diagnostic criteria for dementia.

What is less widely appreciated is that these functional changes can emerge years before dementia is diagnosed, providing an early signal that the brain may be at risk. Even when memory seems intact, persistent new struggles in daily tasks may indicate that cognitive decline is starting quietly.

Persistent versus temporary struggles

Recent studies tracking older adults without dementia have found that those who experience persistent difficulties in activities of daily living (like preparing meals, shopping or driving) face a higher risk of developing Alzheimer’s disease in the years ahead. In addition, these persistent impairments are linked to biological markers of the disease, detectable in spinal fluid long before memory loss becomes obvious. By contrast, temporary or occasional difficulties do not carry the same risk.

One of the key insights in this new research is the difference between temporary lapses and persistent functional changes. While almost everyone misplaces keys or forgets a name from time to time, chronic struggles that linger or worsen over months and years may reveal early disruptions in the brain’s ability to co-ordinate complex tasks.


This article is part of our series The Grey Revolution. The Conversation Canada/La Conversation invites readers to examine the far-reaching impacts of the aging baby boomer generation on Canadian society — from housing and employment to culture, food, travel and health care. The series explores the transformations already underway, as well as those still to come.


These disruptions can be one of the earliest indicators that cognitive decline is on the horizon, even before conventional cognitive tests can detect it.

Families, especially those who live with or spend time daily with an older adult, are often the first to notice subtle but steady changes in function, like moments when their loved one struggles to follow a familiar schedule, double-checks every step in a process that used to be second nature or avoids tasks that were once routine. Recognizing these patterns early can help families seek timely evaluation, support and planning.

Looking beyond cognitive screening tests

These findings also underscore the value of integrating functional assessments into routine health care. Traditionally, cognitive screening has focused on memory, attention or language tests. More recently, including assessments of changes in behaviour or neuropsychiatric symptoms have been included in dementia guidelines, even at screening of cognitively unimpaired older persons.

Measuring the ability to manage daily life may provide a window into brain health that is both a practical and potentially more culturally adaptable approach to early detection than cognitive screening. Standard cognitive screening tests can be affected by language, education or cultural background. For example, someone may score lower simply because the test uses unfamiliar words, assumes certain schooling or reflects cultural norms that differ from their own.

In contrast, observing changes in everyday function over time focuses on real-life abilities and can reveal early signs of brain changes, offering a practical and widely applicable way to detect risk.

Shifting the focus in aging and brain health

The story of everyday struggles as early warning signs challenges common perceptions of aging. What looks like normal forgetfulness may, in some cases, be a signal to pay closer attention. These subtle changes are not personal failures — they are clues, pointing to the need for care, support and awareness.

It’s also important to keep this in balance: not every struggle points to dementia, and many older adults maintain their independence without experiencing any decline in daily functioning. But for those whose difficulties persist and accumulate, the pattern is meaningful.

Based on the latest research, it is this persistence, rather than occasional slips, that is most strongly linked to future cognitive decline and brain changes associated with Alzheimer’s disease.

By shifting the focus from episodic forgetfulness to ongoing functional changes, families and health-care providers can act sooner. Support strategies, such as simplifying routines, using reminders or providing assistance with complex tasks, can help maintain independence while also serving as a form of early intervention. Early recognition also allows for better planning, access to resources and timely medical evaluation.

A window into brain health

Ultimately, the story of functional change in aging is one of vigilance and insight. Paying attention to what may seem like small, everyday difficulties can offer a glimpse into the brain’s health years before memory loss becomes obvious. It’s a reminder that the subtle ways life becomes harder can carry vital information, and that early attention to persistent changes may make a meaningful difference in the course of aging and cognitive health.

If you’re interested in contributing to research on everyday function and brain health, Canadian studies like CAN-PROTECT and BAMBI are exploring how subtle changes in daily life may signal early risk for Alzheimer’s.

Si vous donnez une tâche ingrate à vos salariés, vous allez le regretter

Source: The Conversation – in French – By Rahman Khan, Associate professor, PSB Paris School of Business

Entre 30 et 50 % des salariés doivent effectuer des tâches sans lien avec leur poste ou leur expertise professionnelle. Résultat, ils deviennent silencieux, gardant pour eux leurs questions ou leurs suggestions, bien qu’elles pourraient s’avérer utiles pour l’entreprise. Alors, comment sortir de cette dynamique perverse ? Car, le silence des salariés n’est qu’un symptôme d’une entreprise malade.


L’image d’Épinal du stagiaire « responsable machine à café » ou « photocopieuse » traduit une réalité. Dans certaines entreprises, des employés en contrat limité ou non limité, souvent surdiplômés, doivent se cantonner à réaliser des missions ingrates. « Tu veux bien passer les slides PowerPoint pour ma présentation ? »

Dans une recherche récente, nous avons étudié la façon dont les tâches assignées déterminent le comportement des employés, en particulier lorsque ces tâches sont perçues comme illégitimes – considérées comme déraisonnables, inutiles ou ne correspondant pas au rôle des employés. Une étude complémentaire rappelle que de telles tâches ne sont pas une simple source de désagrément. Elles influencent la manière dont les employés perçoivent l’équité et leur place au sein de l’organisation, au-delà d’être des facteurs de stress.

Le silence est une réponse courante à l’illégitimité perçue. L’effet secondaire : les employés peuvent cacher des informations qui pourraient aider leurs équipes, comme leurs préoccupations, leurs idées ou leurs suggestions. Alors, comment fonctionne ce mécanisme pervers pour l’entreprise et pour les salariés ?

Tâches injustes sans mauvaises intentions

Les employés qualifient certaines tâches d’injustes lorsqu’ils constatent un décalage avec leur rôle, leur statut professionnel ou l’objectif de leur poste. Cette évaluation reflète la perception des employés et non les intentions de leur responsable.

Une tâche peut être donnée sans mauvaise intention, mais tout de même être perçue comme injuste quand elle entre en conflit avec les attentes liées à un poste ou qu’elle témoigne d’un mépris pour l’expertise professionnelle. Des études sur les tâches illégitimes établissent une distinction entre les tâches qui ne relèvent simplement pas d’un rôle précis et celles qui sont considérées comme inutiles.

Les deux cas remettent en question la manière dont les employés définissent leur contribution au travail. Lorsque les tâches vont à l’encontre des normes du métier, les employés se sentent méprisés dans leur identité professionnelle.

De 30 % à 50 % des salariés concernés

Les enquêtes indiquent que les tâches illégitimes sont monnaie courante dans le milieu professionnel. Entre 30 % et 50 % des employés sont confrontés, au moins occasionnellement, à des tâches déraisonnables ou inutiles, avec des variations importantes selon les professions et les secteurs.

Le phénomène est particulièrement fréquent dans les environnements à forte surcharge de travail et où les rôles sont flous. Des rôles mal définis augmentent le risque que les employés se voient confier des tâches ne relevant pas de leurs responsabilités officielles. Les environnements à forte charge de travail intensifient ce phénomène, car les managers s’appuient sur une délégation ad hoc pour répondre au besoin immédiat de l’entreprise.

L’injustice organisationnelle va de pair avec un silence accru, les employés choisissant de ne pas partager leurs idées même lorsque celles-ci pourraient être très importantes pour l’organisation. Le silence est notamment utilisé délibérément pour exprimer son désaccord avec l’attribution injuste des tâches.

Moins de sincérité dans l’entreprise

Le silence des employés traduit une tendance à ne pas communiquer à ses supérieurs ou à ses collègues, intentionnellement, des informations ou des suggestions liées au travail, même lorsque les exprimer pourrait être utile. C’est une décision délibérée. Le cas d’un silence délibéré peut traduire un motif de représailles ou de vengeance à la suite d’une injustice perçue.

Le silence, un outil de performance managériale sous-estimé


Il existe une différence entre silence et désengagement. Des employés désengagés fournissent globalement moins d’efforts, tandis que les employés silencieux restent impliqués dans leur travail, mais communiquent moins. Concrètement, ils ne souhaitent pas exprimer sincèrement leur opinion sur les conditions de travail à ceux qui sont en mesure d’y répondre.

Un traitement inéquitable et une injustice organisationnelle sont susceptibles d’entraîner un silence défensif, où les employés évitent de partager des informations afin de se protéger d’éventuelles conséquences négatives.

En revanche, le silence délibéré est dirigé vers l’organisation en réponse à une répartition des tâches jugée injuste. Les employés sont plus enclins à garder le silence lorsqu’ils s’attendent à :

La morale influence les réactions des salariés

La moralité des employés – leur sens du bien et du mal – détermine leur comportement éthique au travail. Par exemple, les employés ayant une forte identité morale sont moins susceptibles de tricher au sein de leur entreprise.

Cette conduite morale, traduction d’une conception de soi en entreprise, guide le comportement des salariés. Les employés qui valorisent des traits moraux importants pour leur image d’eux-mêmes, comme le fait d’être juste et bienveillant, sont plus à même d’éviter les comportements négatifs au travail, tels qu’un silence motivé par la vengeance, contraire à leurs valeurs morales.

Cette éthique individuelle a ses limites. En réalité, elle ne permet pas de déceler pleinement les systèmes injustes ni les environnements de travail toxiques. Lorsque la répartition des tâches et les processus de prise de décision restent constamment inéquitables, le silence persiste, même lorsque les employés ont une image morale élevée d’eux-mêmes.

Ce que les entreprises peuvent apprendre

La délégation des tâches reflète la manière dont les employés sont considérés au sein d’une organisation. La répartition des tâches est un signe de respect et de statut, mais aussi d’inclusion.

La perception d’une répartition des tâches équitable favorise la confiance et la coopération, tandis qu’une répartition inéquitable est source de tension et de ressentiment. Il n’est pas surprenant que les employés confrontés à cette dernière se plaignent davantage d’épuisement émotionnel et d’une baisse de leur bien-être.

La légitimité de la répartition prime sur les objectifs d’efficacité au sens strict. Des processus équitables renforcent les normes d’échange social et l’engagement en soulignant que chaque contribution est reconnue à sa juste valeur. Parallèlement, l’attribution des tâches sur la base de la justice est corrélée à un engagement plus fort et à une diminution des réactions de retrait.

Le silence des employés n’est qu’un symptôme. Les organisations devraient donc être attentives au silence de leurs employés et à leurs pratiques d’attribution afin de détecter les problèmes de légitimité avant que des conflits ouverts ou des départs ne surviennent.

Canada’s new TikTok compromise fails to resolve questions of ownership and national security

Source: The Conversation – Canada – By Philip Mai, Co-director and Senior Researcher, Social Media Lab, Toronto Metropolitan University

The Canadian government has reached an agreement with the social media platform TikTok after years of debate over the app’s data practices, particularly those affecting young users. The deal allows TikTok to continue operating in Canada under tighter oversight rather than facing a shutdown.

As social media researchers at the Social Media Lab at Toronto Metropolitan University, we’ve always paid close attention to the state of social media in Canada. We have followed the TikTok ban saga closely since early 2020, when United States President Donald Trump first tried to ban the platform, long before he later came out in favour of keeping it.

While the new agreement does move towards greater oversight of TikTok, major concerns remain. TikTok’s parent company, ByteDance, is based in China and Chinese national security laws can compel companies to co-operate with state authorities. This underlying risk sits beyond the reach of Canada’s safeguards.

The agreement follows a new national security review that reversed an earlier conclusion pointing toward closure of TikTok’s Canadian operations. Instead of a ban, the federal government has chosen a regulatory approach, one that keeps the app available while imposing legally binding conditions. The deal reduces some risks, but it does not resolve deeper questions about ownership, data flows and national security.

So what has TikTok agreed to? And what will the millions of Canadian users, creators, advertisers and cultural groups that rely on the platform notice?

Stronger protections for youth and minors

Under the new rules, TikTok must strengthen its protection of Canadian user data. This includes creating a security “gateway” to control access to that data, adopting privacy-enhancing technologies and allowing independent third-party monitoring to verify how data is handled.

TikTok also committed to stronger protections for minors and youth, a key concern driving the government’s review.

For everyday users, the focus on youth protection is likely to be the most visible change. Stricter age limits could affect livestreaming. Gift features may be more restricted for younger users. Content involving minors is likely to face stricter moderation.

Canadian creators will also feel the impact. Those with audiences largely made up of teenagers may face tighter moderation or additional eligibility checks for certain features and monetization tools. Sponsors may also ask more detailed questions about audience demographics as brands become more cautious about youth-focused content.

Many changes will happen behind the scenes. As TikTok Canada adjusts to the new requirements, its verification processes, advertising tools and moderation systems are expected to become more demanding.

As the government now requires stronger protection of Canadian user data, people who earn money on the platform may encounter extra steps. These may include stricter identity checks, added requirements for business accounts or ad payments and clearer information about where Canadian user data is stored.

Does TikTok pose a security threat to Canadians?


Does this make TikTok safer? Compared to what existed before, the agreement does move toward greater oversight. Independent monitoring, if carried out properly, gives the government some visibility into TikTok’s data practices and the commitments are legally binding rather than voluntary.

Canadian data can still leave Canada

Enforcement details are still unclear. The government has said it will appoint an independent monitor, but has not named the monitor, explained how audits will work or detailed what penalties TikTok would face for failing to comply. Without clear consequences, oversight could prove weaker in practice than it appears on paper.

The agreement also stops short of requiring full data localization. Canadian user data does not have to stay entirely within the country. Although technical controls may limit access, data can still move through systems outside Canada. This leaves some exposure to unauthorized access or foreign influence.

Another gap is research access. The deal does not require TikTok to share data with vetted Canadian public-interest researchers, like academics or journalists. Currently, researchers from Canada are not qualified for access to the TikTok application programming interface (API), while their counterparts in the European Union and U.S. are. This makes it harder for Canadian researchers to independently study the platform’s impact on Canadian users.

A cautious compromise

Overall, the agreement reflects a compromise. Canada avoided a disruptive ban; TikTok accepted tighter rules to keep operating in a key market. The deal reduces some risks, but it does not resolve deeper questions about ownership, data flows and national security.

Those tensions are likely to resurface as Canada continues to grapple with how to regulate global platforms that play an outsized role in everyday life.

The world’s waste mountain is rising at an alarming rate

Source: The Conversation – UK – By Costas Velis, Lecturer in Resource Efficiency Systems, School of Civil Engineering, University of Leeds; Imperial College London

The world is struggling to deal with ever-growing quantities of waste.

A new World Bank Group report, What a Waste 3.0, shows that more than 2.6 billion tonnes of municipal solid waste (which includes rubbish from households, businesses and street cleaning) were generated in 2022. That figure is projected to rise to 3.9 billion tonnes by 2050. The good news is that the share of waste that is mismanaged is expected to fall over that period, from around 30% to around 20%.

That sounds like progress. But percentages can be misleading. The quantity of mismanaged waste, including plastics, is projected to remain almost unchanged, at around 760 million tonnes. This means that by 2050, enormous quantities of waste will still be openly dumped, burned or otherwise unmanaged, with many households and communities left to deal with it themselves.

This new report, which we contributed to, brings together the most recent publicly accessible municipal waste data from 217 countries and economies (such as the Channel Islands) and 262 cities. It highlights that although waste systems are improving in many places, those gains are being undermined by the growth in the amount of waste generated.

Stacked bar chart showing projected global municipal solid waste treatment under a business-as-usual scenario from 2022 to 2050. Total waste rises from 2,562 to 3,855 million tonnes per year, while the mismanaged share falls from 30% to 20%.

This matters because when waste is not managed properly, the consequences affect human health, the environment and the economy. Poor waste management contributes to air and water pollution, damages ecosystems, increases greenhouse gas emissions and makes cities harder and less pleasant to live in.

One of the clearest examples is open burning. In many developing countries, where formal waste collection remains incomplete or absent, open burning is one of the main ways households and communities “self-manage” their waste. These fires burn at low and uneven temperatures. Combined with a mixed waste stream that can include plastics, organics and other materials, they release a complex cocktail of pollutants that can threaten the health of people living and working nearby.

With new data on self-management, this report shows how waste is actually managed across large parts of the world, especially where formal systems remain weak. Forms of self-management of waste include open dumping, open burning, burying waste in informal pits, dumping into waterways and coastal waters, and some forms of informal recovery such as recycling or composting.

Health crisis: up to a billion tonnes of waste potentially burned in the open every year


So if the harms of poor waste management are well known, why does the problem persist?

One reason is cost. Municipal waste management is resource intensive. Many countries are still spending far less than is needed to provide universal and reliable services. Our analysis suggests that even basic systems involving collection, transport and disposal tend to cost at least US$40 (£30) to US$45 per tonne in low-income countries. In middle-income countries, basic systems cost roughly US$70 to US$80 per tonne, while in high-income countries costs can exceed US$200 per tonne.

At those cost levels, low-income countries would have needed around 0.78% of their combined GDP in 2022 to achieve universal waste management coverage. Middle-income countries would have needed roughly 0.31% to 0.46% of GDP. Yet reported public spending on solid waste management is less than 0.15% of GDP in about three-quarters of low- and middle-income countries and 0.31% in high income countries.

That financing gap helps explain why waste collection is not comprehensively provided, why open dumping is still common and why so many people are left to manage waste themselves.

Around 2 billion people do not have access to solid waste collection, meaning they have to manage it themselves, often through dumping and open burning, as in Nizamat Fort Campus, West Bengal in India.

The total financial costs are also rising fast. Globally, municipal waste management cost more than US$250 billion in 2022. Under a business-as-usual scenario, that annual cost is projected to reach US$426 billion by 2050.

Shifting the costs

The cost of inaction is higher than these service costs alone suggest. Poor waste management brings wider economic losses, for example through ill health, reduced land values, damaged ecosystems, lost materials and harm to sectors such as tourism, agriculture and fisheries.

The world may not be saving money by underinvesting in waste management. It is shifting the costs elsewhere – onto public health, the environment and future generations.

This is especially important in low- and lower-middle-income countries, where waste generation is rising rapidly, but service coverage and infrastructure are often far below sufficient levels. This report estimates that these countries will require hundreds of billions of dollars in investment over the next 25 years just to expand and improve municipal waste systems. Without faster investment, existing service gaps will widen and the costs of inaction will grow.

The world’s waste crisis cannot be understood only as an environmental problem. It is also a financing, public health, governance and development problem. Better data helps us see that more clearly.

Waste management is improving, but not fast enough. Unless investment and performance accelerate, the amount of mismanaged waste worldwide is unlikely to change, causing harm to public health.

Lady Day: March 25 was the start of the year in England and Wales until 1752

We associate New Year with deep mid-winter and the tidy date of January 1, but for 600 years between 1155 until 1752 in England and Wales the new year began on 25 March. This day was one of the quarter days that divided the year historically and on which rents and debts were settled. March 25 became the quarter day where annual accounts were finalised. So, around about now, we’d have been preparing to welcome in a new year alongside the warmer weather and spring blooms.

Celebrations were double as the legal and ecclesiastical calendar worked in harmony as March 25 is also Lady Day or the Feast of the Annunciation. Falling exactly nine months before Christmas Day, for Christians it marks when the archangel Gabriel informed Mary that she was shortly to bear a son.

Feast days are normally days of indulgence and merrymaking, but Lady Day normally falls in Lent, a time of abstinence. This meant, for some, Lady Day was a temporary lightening of Lenten restrictions.

Also known as Annunciation Day, Lady Day has sometimes fallen on Good Friday, as it did in 1608. This day is the opposite of a feast day, marking the crucifixion and death of Christ, which is observed through fasting and abstinence. The poet John Donne reflected on this crossover in 1608 in Upon the Annunciation where he saw it as an opportunity to be extra pious:

“Tamely, frail body, abstain today;
today My soul eats twice,
Christ hither and away”

So for Donne, this was a day of fasting and reflection to commemorate both the coming of Christ and his death.

Superstitions

Lady Day has many associated superstitions. An anonymous pamphlet printed in 1721 called When my Lord Falls in my Lady’s Lap, England Beware of a Great Mishap takes its title from an old saying that means that it is unlucky when Lady Day falls on or near Easter Sunday. The author proceeds to run through the many calamities that have happened on such inauspicious occasions.

For instance, it tells of how in 1117 the heir to Henry I, William Adelin was drowned in the sinking of the White Ship along with 300 other souls. The author hasn’t got their facts quite straight here as this disaster happened in November 1120. By Victorian times, this superstition about Lady’s day falling near Easter Sunday was considered old fashioned with The Hampshire Advertiser describing it as a “former ill omen” in its 21 March 1846 edition.

Customs

Lady’s Day is still celebrated in some parts of the UK. In Hampshire, The Tichborne Dole on Lady’s Day dates back to around 1150. Mabella (or Isabella), Lady de Tichborne of Alresford, made a deathbed request that an annual donation of bread, baked with grains from her lands, be made in her memory to the parish poor.

Her rather less charitably minded husband, Sir Roger, agreed on condition that his benevolence was limited to crops from just the land that she could walk around while carrying a single burning log from the fire. According to the legend, the dying Mabella crawled her way around some 23 acres before the flame went out. This area is still known as “The Crawls”.

It’s said Mabella left a curse on the house that if ever the dole was stopped the family line would die out. Specifically, she vowed that a generation of seven sons would be followed by a generation of seven daughters. The dole continued uninterrupted until 1794 and it would seem that Mabella’s curse came to pass when the last male Tichborne had a family of seven daughters. And so, the custom was reinstated.

A film, The Tichborne Curse, was released in 1947. The reinstated Dole is still taking place today. Adults from the parishes of Tichborne and Cheriton are entitled to claim one gallon (2kg) of flour, and children half a gallon each.

Always in April

The dating system in the US, Britain and Ireland changed in 1752 when these countries adopted the Gregorian calendar. Then the legal New Year in these countries became the same as it had been in Scotland for the last century and a half: January 1.

However, it wasn’t just the year start that needed adjusting, as the new calendar was now out by several days. This meant that in England, 11 days were “lost” as Wednesday September 2 1752 was followed by Thursday September 14 1752 in order to right things. The jump must have been very disconcerting if we consider how much the clocks going forward an hour throws us out for a while.

In Britain, the legacy of the old-style dating system lives on in our tax system. Where the new tax year was March 25 (the old New Year) it was moved to April 5, and later to April 6, due to the leapfrog in dates 1752.

This day became Old Lady Day. April 6 day now stood in for the financial aspects of the quarter day, which meant this was the date in which new leases on farms and land began and often farm labouring families moved into new tied housing on that day as they signed new year long contracts. Author Thomas Hardy includes this in his 1891 novel Tess of the d’Urbervilles. Tess is hired on a farm upon “her agreeing to remain till Old Lady-Day”.

So March 25 may be a day that for most goes by with little notice now but it was once a major holiday that marked the beginning of the new year.

My unsung hero of science: Buckminster Fuller, the architect who wanted to redesign the world (and inspired a nanosized one)

Source: The Conversation – UK – By Antonios Kelarakis, Reader in Polymers ad Nanomaterials, School of Pharmacy and Biomedical Sciences, University of Lancashire

On November 14 1985, a letter announcing the discovery of a superstable species of carbon appeared in the science journal Nature. Even the letter’s title, C₆₀: Buckminsterfullerene, caused a stir among the journal’s scholarly readers.

Molecules are usually named with sterile precision. This one was named after the American architect and futurist Richard Buckminster Fuller (Bucky to his friends), whose geodesic domes had become icons of modern design in the 1950s and 60s.

Fuller’s spherical domes were designed to be lightweight yet strong, with each triangular element distributing stress evenly across a curved framework. C₆₀ was the atomic analogue of these domes, built not from steel struts but carbon atoms – each joined by strong bonds with three of its neighbours to create a tiny spherical cage.

This new allotrope of carbon was so stable and symmetric that it redrew the map of molecular architecture. It kicked off a scientific sprint that led, barely a decade later, to the 1996 Nobel prize in chemistry for English scientist Harold Kroto and his American colleagues Robert Curl and Richard Smalley for their discovery.

Fullerenes (now nicknamed Buckyballs) had always existed on Earth – in candle soot, volcanic emissions and ancient minerals. But their scientific discovery emerged from an attempt to simulate the chemistry of carbon-rich red giant stars.

The discovery opened the era of nanotechnology – the manufacture and manipulation of materials at previously impossibly small scales. But this is not the only way Fuller’s name is remembered in science.

Who was Buckminster Fuller?

Few 20th-century figures are as hard to classify as Fuller. He was, at the least, an inventor, designer, engineer, writer, philosopher and futurist. Born in Massachusetts in 1895, his formal education was brief and rather turbulent – he was expelled twice from Harvard University. Yet this did not lessen his ambition to redesign the world.

Fuller could be eccentric and sometimes controversial. His early enterprises frequently failed, yet his charisma and boundless optimism made him a compelling public figure. The result was a remarkable portfolio of inventions and concepts, showcasing bold prototypes and radical ideas.

His earliest geodesic domes were built from lightweight materials, typically steel tubular struts connected in a triangular lattice and clad with acrylic panels. They capitalised on the structural advantage of symmetry: enclosing a vast space with relatively little material and remaining exceptionally strong.

Fuller patented the design in 1951. Despite initial scepticism from some in the architectural establishment, geodesic domes soon found practical applications. The US Marine Corps used them for rapidly deployable radar stations in Arctic conditions.

One of the most famous examples is the giant dome built for the Expo 67 international exposition in the Canadian city of Montreal. Known today as the Montreal Biosphere, the structure became one of the most recognisable symbols of futuristic architecture in the 1960s.

Alongside his designs, Fuller spent much of his life developing Synergetics, a philosophical-geometric framework exploring how structures and energies interact in nature. At the heart of this work was “ephemeralisation” — a term Fuller coined to describe the process of achieving ever greater results with fewer materials and less energy.

In later life, he became a global intellectual celebrity, delivering thousands of lectures around the world. Fuller captivated audiences with a unique vision of design, technology and planetary stewardship — once delivering a marathon series of lectures entitled “Everything I know”. It ran for 42 hours.

The power of symmetry

Symmetry is among science’s most powerful unifying codes and one of its most versatile interpretive tools. It reveals surprising equivalences between forms that differ in size but not in structure.

In the 1960s, footballs adopted a similar geometry to Fuller’s geodesic dome: a combination of 12 pentagons and 20 hexagons stitched into a resilient mesh to absorb force and rolls with minimal deformation. Indeed, a diagram of a football was used to illustrate the announcement of C₆₀: Buckminsterfullerene.

This series is dedicated to lesser-known, highly influential scientists who have had a powerful influence on the careers and research paths of many others, including the authors of these articles.


A growing family of atom-thin, superstrong materials has emerged since that 1985 Nature letter. These include the tiny-in-diameter but much longer carbon nanotubes in 1991, and the one-atom thick graphene in 2004 – both of which are now widely used in electronics, sensors, composites and energy devices.

When added to polymer composites or metal alloys, these tiny carbon cages strengthen and lighten materials, enhancing performance in everything from aircraft components and solar panels to medical tools including MRI scanners.

Doing more with less

The structure of fullerenes naturally realises Fuller’s principle of ephemeralisation – the ability to do more and more with less and less.

Fuller imagined technological progress as a path toward efficiency, elegance, sustainability and abundance. He applied ephemeralisation across his designs, harnessing science and geometry to achieve maximum performance with minimal resources.

Beyond geodesic domes, his innovations included the Dymaxion House – a prefabricated, environmentally efficient home designed for easy mass production and transport – and the Dymaxion Car. Patented in 1933, its streamlined aerodynamic bodywork was designed to carry more passengers while improving both fuel efficiency and top speed.

Fuller also imagined radical solutions for extreme environments. These included the Undersea Island – a submerged base anchored by crisscrossing cables to stay rock steady in storms – and the suspension building system, which inverted the idea of a suspension bridge into an arched dome that created vast interior space with minimal material.

Fuller died in 1983 after a lifetime spent redesigning the world – and reimagining how humanity might live. Two years later, chemistry paid him an unexpected tribute: a perfectly symmetrical carbon molecule was named after him, recognising his lifelong dedication to geometrical efficiency.

In the nanosized Buckyball, Fuller’s aspirational social ideas are encapsulated in a molecule that embodies minimalism, efficiency and intelligent design.

Showing shoppers the ‘cost per wear’ of their clothing choices could make fashion greener

Source: The Conversation – UK – By Lisa Eckmann, Assistant Professor in Marketing, University of Bath

Imagine a man wants to buy a new shirt for work that he plans to wear once a week for at least the next five years. When browsing for options, he finds one shirt from a lower-quality brand priced at £20 and one shirt from a high-quality brand for £50. Which one should he buy?

From his previous experience with the two brands, he knows that if he plans to wear the shirt once a week (so roughly 50 times per year) the lower-quality shirt will last him about a year. After that, he will need to replace it. The high-quality shirt will be good for at least four years. But clearly, the high-quality shirt is also more expensive.

Our theoretical shopper would probably conclude that the high-quality shirt makes more economic sense. Taking into account the purchase price relative to how many times he can wear the shirt, it would cost him only 25 pence for each time he would wear it, compared to the lower-quality shirt at 40 pence.

This is the logic of “cost per wear”. Some fashion blogs and small businesses have started using this concept to make the case for high-quality clothing. The rationale is simple – higher-quality clothing should last longer, making a higher purchase price worthwhile in the long run. Cost per wear is calculated by dividing the garment price by the number of times the consumer expects to wear it.

Essentially, cost per wear works much like unit pricing in supermarkets. These measures already help consumers compare things like the price of a product per 100g, per chocolate bar in a multipack, or per laundry load. But this same logic isn’t yet applied to clothes in a retail setting.

The fashion industry is one of the largest contributors to environmental harm, accounting for up to 8% of the world’s carbon emissions, causing immense water pollution due to textile treatments such as dyeing, and producing millions of tonnes of textile waste annually.

Using cost per wear in shops or online retail spaces could reduce the environmental impact of fashion – the more frequently a garment can be worn, the more efficiently the consumed resources are used. And of course the longer that garment remains in use, the less often it needs to be replaced.

The problem is that most shoppers don’t know how long a garment will last. Without a prompt in stores or online, many consumers do not even consider clothing longevity when buying.

But standardised fabric-testing methods exist already. These methods assess the durability of fabric according to the number of abrasion cycles (that is, the number of rubs against an abrasive surface) it can tolerate before showing signs of wear. This could easily be applied to clothing, allowing retailers to include cost per wear labels alongside the purchase price.

In research I carried out with Lucia Reisch from Cambridge Judge Business School, we tested this idea. In a number of experiments, we showed participants from online panels a lower-quality, cheaper garment (a sweater, for example) and a higher-quality, more expensive version. We then asked which they would prefer.

Fast fashion suddenly wasn’t so affordable

When we included information on the cost per wear for both options – or even just the high-quality option (showing a lower cost per wear compared to a poorer-quality option, or a reference value), participants were more likely to choose the more expensive, high-quality option.

The effect was stronger when participants were shopping for everyday wear over occasion wear, when they could compare the cost per wear between options, and when the cost per wear information was said to be certified by an independent third party. Participants then trusted the information more, and we found that this could outperform a general durability claim made by a brand.

Our studies showed that cost per wear can make cheap fashion suddenly appear more expensive to shoppers – the high-quality options were viewed as better financial investments. And by choosing the more economical, high-quality option, participants were also choosing the greener option.

Cost per wear can increase the perception of affordability for more expensive, high‐quality clothing. But of course many shoppers will still not be able to afford the higher purchase price even though they know it would make more long-term economic sense.

And cost per wear only reflects the durability of an item as one dimension of sustainability. It does not reflect ethical considerations, such as the conditions workers face in the production process, or ecological aspects such as the use of natural or synthetic fibres.

Brands and retailers must also be willing to display cost per wear labels without regulation. High-quality brands may arguably have a greater incentive to do so than fast fashion brands.

However, the concept of cost per wear is still worth pursuing. It can prompt shoppers at the point of purchase to consider a garment’s durability and how often they might wear it. And ideally, it would motivate them to ditch fast fashion and choose greener options – even if just to save money in the long run.

Rising energy prices will hit millions: here are three ways the UK government could shield vulnerable households

Source: The Conversation – UK – By Cassandra Etter-Wenzel, PhD Candidate in Energy Policy, University of Oxford

Even before the US-Israel war on Iran, people in the UK were unusually vulnerable to sudden swings in the cost of energy. Depending how you count it, either 11% or 30% of households are officially energy poor, and already struggled to afford basic needs in times of relative peace.

The government’s fuel poverty strategy for England, published in January 2026, focuses on long-term measures such as home insulation upgrades. But it says little about how to protect vulnerable households quickly in this crisis or in future price shocks.

To reduce the immediate harm, ministers need tools that can be deployed now, not just reforms that may take years to deliver.

Here are three measures that could be deployed right now.

A social tariff

The most effective step would be to discount energy bills for lower-income or vulnerable households – a so-called “social tariff”.

This is often seen as difficult or politically risky. But energy remains one of the few essential services without targeted affordability support. Water and telecoms already enjoy it, and energy should be no different.

In a policy brief we published late last year, we showed that the UK electricity system hits lower-income households hardest and produces “uneven bills”. This means that two households using the same amount of electricity can face differences in bills of up to 15% depending on where they live, and another 22% depending on payment method or contract type.

A social tariff would be fairer. Through a lower unit rate or a bill discount it would protect households with the least room to cut energy use – such as older people, low-income households, those with medical-related electricity needs and renters in inefficient homes.

These policies can also encourage energy efficiency. For instance, in California, the state’s Care programme discounts electricity and gas bills for low-income households up to a set level of use. Beyond that point, rates revert to normal.

This is not unrealistic administratively. Portugal introduced automatic eligibility for its social energy tariff in 2016. This used existing tax and social security data to expand the number of households receiving support by 400%.

The UK already has the data infrastructure to do something similar through its benefits and tax system – energy companies wouldn’t have to find out household incomes themselves; they could just ask the government. The near-term step here is straightforward – ministers could ask the industry regulator Ofgem and energy companies to design an automatic, income-linked tariff for winter 2026, instead of waiting for another crisis response.

Emergency support

The second priority is to reduce immediate exposure to the most volatile and expensive fuels.

Government has traditionally responded to shocks like the Ukraine war with emergency bill support. However, these ill-targeted policies are impractical and do not reduce reliance on volatile fossil fuels. Unlike a social tariff, which is a continuous means-tested support payment, emergency support is often a one-off payment. Traditionally, emergency support is a flat payment to all households, meaning those on lower incomes benefit less in relative terms, though it can also be targeted at vulnerable households.

Transport is one immediate opportunity. Rather than (yet again) freezing fuel duty, the government could redirect this money into cheaper public transport for low-income and car-dependent households.

Germany’s €9 (£8) public transport ticket, introduced in 2022 during the energy and cost-of-living crisis, shows that governments really can act quickly when necessary.

Households that are off the gas grid and reliant on heating oil are especially exposed when global prices rise. Alongside short-term support, like the welcome £50 million announced last week, the government should consider targeted support to switch from oil to heat pumps. The economic case for heat pumps is especially strong for households relying on heating oil. This switch would immediately reduce their exposure to oil prices.

Help households access existing savings

The third priority is to ensure vulnerable households can benefit from money-saving features that are already available in the electricity system.

Smart meters, time-of-use tariffs and shifting electricity use to cheaper times of day can cut bills, but the savings are not automatic. Those who could benefit most are often least likely to be able to access them.

The near-term priority is not new schemes, but making existing ones usable. The government could require suppliers, local authorities and landlords to prioritise smart meters and other low-carbon technologies in social housing and private rentals, where people face the greatest barriers to accessing these savings. It could also fund trusted community organisations to help households choose suitable tariffs, avoid poor deals and access support if they fall into arrears.

This may sound less dramatic than a new subsidy scheme, but clarity matters in a price shock. Households cannot benefit from cheaper tariffs or smart systems they do not know about or cannot use, so financial support often flows most to those already best placed to respond.

The UK cannot prevent global energy price shocks, but it can choose who bears its greatest burden. What is missing is political will. If the government is serious about protecting vulnerable households, it needs a strategic short-term response that matches the scale of urgency.

Golders Green ambulance attack: how this part of London became a home for Jews

Source: The Conversation – UK – By Tony Kushner, James Parkes Professor of Jewish/non-Jewish Relations, University of Southampton

The arson attack on four ambulances in Golders Green early on March 23 has been called “a horrific antisemitic attack” by the prime minister, Keir Starmer.

These ambulances were run for the benefit of both the local Jewish and non-Jewish communities in this district of north London by a charity called Hatzola – meaning “rescue” in Hebrew. As these ambulances played a key supportive role in enabling access to health provisions for the good of all, it is especially shocking – and has further heightened the anxieties of British Jews.

This is a community still reeling after the attack on the Heaton Park Synagogue in Manchester in October 2025 on Yom Kippur, the holiest day of the Jewish religious calendar, which killed two people. And the arson attack is part of a wider international wave of antisemitism, which has included Norway, the US and the Netherlands in the past few weeks. This is not an easy time to be a diaspora Jew.

Those who have carried out the attacks have come from different backgrounds. Many have been influenced by online hate emanating from Isis, and potentially individuals or groups supportive of the hardline Iranian regime. Counter-terror police are investigating whether an Iran-linked group is responsible for the arson. The terror group Harakat Ashab al-Yamin al-Islamiya (The Islamic Movement of the People of the Right Hand) has claimed responsibility for the attack, as well as others in Europe.

These attacks reflect the complex pattern of hostility towards Jews in the UK, which has been through a mixture of domestic and foreign-inspired hatred. In terms of the latter, there are several examples going back a century which can be highlighted.

The most well-known is the Jew hatred spread by Oswald Mosley and his British Union of Fascists (BUF), formed in 1932, which was at least partly stimulated by German Nazism.

Overall, however, there are deep domestic roots of antisemitism since the readmission of the Jews in the 17th century after a 300-year expulsion. But it has rarely resulted in violent attacks – even if it has made life uncomfortable for the Jewish minority in moments of crisis.

Golders Green’s rich history

These roots can be seen in relation to Golders Green which started to develop as a place of Jewish settlement from the first world war onward. While there were some Jews in this then small suburb in the 19th century, there was not much in the way of a formal community.

Pam Fox, the social historian of Golders Green’s Jewish community, states that “Before 1910 there was just a handful of Jews living in the community, but by 1915 … there were 300 households”. Growth continued after the first world war, and in 1922 the first synagogue, Dunstan Road, was opened. Today, the Jewish population is around 8,000 and represents some 40% of the suburb’s population.

Such crude statistics do not reflect the diversity of the Jewish population both past and present. As early as the 1930s, more orthodox Jews, some of them refugees from Nazism, were establishing different forms of worship from Dunstan Road, which was more in the form of mainstream orthodox religiosity. By the second world war, there were at least 14,000 Jewish refugees in north-west London (including Golders Green), who varied from the totally secular, to reform, to the very orthodox.

After the war, there were more influxes of Jewish refugees, including from Egypt, Hungary and later South Africa, as well as second- and third-generation Jews whose origins were from eastern Europe and then the East End of London. While the very orthodox are currently the growing group in Golders Green, it still has an incredibly heterogeneous Jewish population.

For most Jews, the vibrant cultural, social and religious life of Golders Green has made it a very comfortable place to call home. Even so, there has been antisemitism – organised in the form of the BUF and more commonly in the form of more casual prejudice.

In late 1945, the Hampstead Petition Movement aimed to remove all foreign Jews from the wider area, and it had some local support. In the Nazi era, local newspapers, including the Golders Green Times, objected to the alleged bad behaviour of the Jewish refugees who were falsely accused of being unpatriotic and selfish.

Today, the idea of Golders Green being a Jewish suburb ignores the reality that most of its population is not of that background. It also forgets the many types of Jewishness that are articulated there. Such nuances are lost on those carrying out the attack on the ambulances, with their universal usage.

It says much about the times that such distinctions are not made – many people hold all Jews responsible for the actions of a particular Israeli government. Yet in Golders Green as elsewhere, Jews for both political, cultural and religious reasons hold a range of attitudes towards the problems of the Middle East. Ultimately, such attacks are, as local Jewish resident Sam Adler put it, “cynical and cowardly”. If nothing else, as with Manchester, they have also brought communities together in solidarity and resistance to the ugliness of antisemitism.
