In the Salish Sea, tensions surrounding killer whales and salmon are about more than just fishing

In the waters of the Salish Sea, endangered southern resident killer whales and the struggling Chinook salmon they depend on are at the centre of one of Canada’s most visible conservation conflicts.

Since 2019, Canada’s Department of Fisheries and Oceans (DFO) has implemented area-based restrictions on Chinook fishing and other protective measures to safeguard the killer whales and their primary food source. These measures include area-based recreational fishing closures, interim sanctuary zones and voluntary seasonal vessel slowdown areas.

These prescriptions have stoked tensions, particularly between two groups often cast as distinct and opposed: recreational fishers and conservationists. The issue has spilled beyond local waters, surfacing on national media and even influencing fishery debates in Alaska.

Conflicts like this one aren’t unique. They surround — and can influence — many modern environmental, social and policy decisions. At their best, conflicts can bring attention to unmet community needs, spark dialogue and repair fractured relationships. But misunderstood or mishandled, they can harden divisions that stymie evidence-based decision-making, deepening distrust.

Too often in North America, default management approaches inflame such conflict rather than resolve it. But new collaborative research colleagues and I have conducted suggests pathways to transform conflict surrounding killer whale protection and Chinook fishing — and may offer broader insight for effectively managing conflicts around conservation efforts.

Our research

We surveyed more than 700 British Columbians, many of whom self-identified as either recreational fishers or conservationists. What we learned from participants has challenged dominant conflict narratives: nearly one-third of those who identified primarily as conservationists also identified as anglers, and almost half of anglers also identified as conservationists.

In other words, many of the people involved in this conflict occupy both sides of public debates, and bear multifaceted identities as they relate to whales, salmon and policy.

Yet public and political discourse about environmental management often reduces conflict to binary opposing opinions: do we support temporary recreational fishing restrictions to protect killer whales, or do we oppose them?

Humans — and conflicts — are not that simple, and treating them as such may be destructive to people, communities, policies and marine ecosystems.

Decades of research show, for instance, that conflicts are shaped not just by opinions, but by deeply rooted psychological characteristics, including identities, beliefs and values. These aspects of conflict are not trivial; they are central to how people make sense of their world, their relationships, and themselves.

We used surveys to measure beliefs, opinions and identity affiliations to assess not only opinions on killer whales and salmon management, but also the identities and beliefs beneath them.

What we found

We found that both anglers and those supporting conservation strongly tied their sense of self and well-being to the environment, as well as to their chosen identity groups (recreational fishers or conservationists). Despite disagreements, both groups valued salmon and whales — and both expressed frustration with DFO’s current management approaches.

We also identified the deeper roots of conflict between participants. Recreational fishers and conservationists differed in what they believed the fundamental priority of environmental management should be.

Conservationist respondents were more likely to emphasize protecting species regardless of their utility to humans, while recreational fishers expressed mixed views. Some agreed with that stance but others felt environmental management should prioritize species that benefit people directly or strike a balance between conservation and use.

One of our most striking findings came from comparing survey responses with social media commentary. When people responded to our survey, they tended to share their views with minimal inflammatory language. In contrast, data we extracted from Facebook discussions about the same issues contained far more hostile sentiments. Online, we saw more frequent expressions of anger, distrust, victimization and even violent rhetoric.

This isn’t surprising. Substantial research has identified that social media can amplify emotional responses, reward polarization and reduce the social cost of hostility. This finding indicates a potential negative feedback loop: when media and online discourse reduce complex conflicts to binary arguments, they risk entrenching people in “us versus them” stances.

Transforming conflict

Given these insights, we propose a fundamental reorientation of how DFO and other managers approach such conflict. Rather than treating conflicts as problems to be managed through superficial consultations or short-term negotiations, decision-makers must address their roots.

This means adopting transformative approaches to addressing conflict: acknowledging deeper social roots of conflict, investing in long-term dialogue and relationship-building and creating space for mutual understanding even without consensus. Research shows it is much easier to find solutions when stakeholders feel seen, included and mutually-respected.

These solutions require time, resources, trained mediators and a commitment to engage with emotional and identity-based dimensions of conflict. They also offer something that current approaches have not: the possibility of durable, locally supported solutions, improved trust and collaboration.

Conflict transformation approaches have proven effective in ameliorating entrenched conflicts between stakeholders over cougar management in the United States, elephant management in Mozambique and elsewhere.

As climate change, habitat degradation and species decline intensify, so will conflicts over environmental decisions. These conflicts may appear to be about salmon, whales or other species, but many of them are ultimately about people: their livelihoods, values, relationships, identities and visions for the future.

Accordingly, we need to stop treating conflict as an inconvenience to be managed or avoided. Instead, policymakers can leverage complex, entrenched conflicts as opportunities to identify the deeper roots of what’s at stake and create dialogue and decision-making frameworks that acknowledge people’s lived realities while building the trust needed for coexistence.

Bilingualism possible in people with rare genetic condition that normally limits speech

Rett syndrome is a rare neurological condition that disrupts physical and linguistic development, affecting around one in 10,000 women and even fewer men. For decades, researchers assumed that people with the condition, many of whom lose speech during early childhood, were confined to a limited range of cognitive and linguistic abilities.

But in Wales, where many families are bilingual and speak both English and Welsh at home, our recent case study showed that access to two languages can help the linguistic growth of someone with the speech-limiting developmental condition Rett syndrome.

Rett syndrome is caused by a random genetic mutation in the MECP2 gene on the X chromosome in most cases. It usually manifests in early childhood, with most people showing typical development before a loss of skills at around 18 months of age. This process, known as “regression”, can lead to a loss of speech, mobility and the ability to use hands purposefully.

There are different variants of Rett syndrome. People with the preserved speech variant may keep the ability to produce speech after regression, develop speech after regression, or develop speech without experiencing regression.

As well as movement and language difficulties, Rett syndrome can also cause scoliosis (curvature of the spine), seizures, irregular heart rhythm, digestive issues and breathing problems. The severity of symptoms varies widely from person to person.

To communicate, many rely on methods such as body language, communication books, symbol charts, or high-tech devices to express themselves. These tools and techniques, known as augmentative and alternative communication, may replace or supplement speech.

While these strategies can be transformative, guidelines on communication methods for Rett syndrome have been based on research involving monolingual people. Until now, the possibility of bilingualism in people with Rett syndrome had not been formally explored.

Early researchers assumed that people with Rett syndrome would be limited to a cognitive ability of an 18-month-old, since this is the point where many experience a regression in skills. Recent research has started to show that this is not the case, with studies concluding that people with Rett syndrome show a range of cognitive abilities.

Bilingualism

In Wales, where 17.8% of the population speaks Welsh, bilingualism is a way of life for many families. Research has consistently shown that growing up with two languages benefits cognitive and linguistic development. For example, bilingual children often demonstrate more efficient thinking skills compared to their monolingual peers.

But parents of children with developmental conditions, like Rett syndrome, are sometimes advised to stick to one language. It often stems from a belief that bilingual exposure might hinder progress or cause confusion. This belief persists despite growing evidence to the contrary.

Studies involving children with other developmental conditions, such as Down’s syndrome, have shown that bilingualism is achievable and does not negatively affect cognitive or linguistic abilities. Moreover, depriving a child from a bilingual family of one of their languages can have social and cultural consequences, cutting them off from a vital part of their identity and community.

Prior to our research, there had been no studies focusing on bilingual development in Rett syndrome. Families had shared accounts indicating that many people with Rett syndrome are growing up in bilingual environments. Some research has explored parental perspectives on bilingualism in Rett syndrome, providing valuable insights into the cultural considerations of bilingualism.

Without research documenting language development itself, though, we had no evidence to show what is possible, or how to best support a bilingual person with Rett syndrome.

Our study focused on a teenage girl with the preserved speech variant of Rett syndrome. She had been exposed to both English and Welsh from birth. Using parental questionnaires, standardised tests and vocabulary diaries, we tracked her understanding and production of words in both languages over three years.

We found she could understand and produce words in both English and Welsh. Her vocabulary in both languages also expanded over time. This challenges long-held assumptions about the linguistic limitations of Rett syndrome. It also opens the door to new possibilities for supporting bilingualism in similar cases.

We are preparing to publish further findings that reinforce these results and explore how bilingualism can be supported in people with Rett syndrome. Future research will be crucial to developing evidence-based recommendations for bilingual language development. This may help to ensure that every person with Rett syndrome has the opportunity to reach their full potential.

Language is more than a tool for communication. It’s a gateway to connection, culture and identity. For people with Rett syndrome, the ability to engage with multiple languages can enrich their lives and strengthen their bonds with their families and communities. Our study is a small but important step towards understanding and supporting this potential.

Trees alone won’t save us: new study says forestation has less potential to fix the climate than hoped

Source: The Conversation – UK – By Heiko Balzter, Director of Institute for Environmental Futures, University of Leicester

More trees aren’t always the best bet. Egmrrsey / shutterstock

Planting trees is seen as a cornerstone of efforts to avert climate breakdown. But a major new study in Science finds their potential has been drastically overstated – and relying on forests to offset carbon emissions could distract from the urgent need to cut fossil fuel use.

The researchers, a team of scientists mostly based in China, looked at both afforestation (creating new forests) and reforestation (restoring cleared ones). Unlike earlier studies, they carefully limited the land assumed to be available to avoid unintended consequences.

For instance, planting trees in snowy regions darkens the surface, since trees are darker than snow. This reduces reflectivity and can actually lead to further warming. Forests can also compete with grassland for water or threaten biodiversity.

Previous studies varied hugely in the area of land that they thought was suitable for planting trees, ranging from 200 million to 2,000 million hectares. Once those unsuitable areas are removed, the new study calculates just 389 million hectares worldwide were left suitable for forestation.

If this whole area was planted, the carbon absorbed by 2050 would amount to about 40 billion tonnes – much lower than previous estimates. But even out of this smaller land area, only about 120 million hectares are currently earmarked for forestation, reducing the climate benefit to only 12.5 billion tonnes of carbon by 2050. That’s a big number, but it’s only slightly more than a single year of global fossil fuel emissions.

Nature-based solutions such as tree planting can help, but they are
nowhere near enough to keep global heating below +1.5°C or even +2°C. Cutting emissions must remain the top priority.

Nevertheless, the authors argue that forestation incentives should be rolled out urgently in countries where the benefits are greatest – particularly Brazil, Colombia, China and India, where wet tropical conditions make trees grow fast. By contrast, in the US and Russia, colder weather and slower tree growth means much more land would be needed to have the same impact.

Implausible pledges

One of the most striking findings of this study is that across Africa, many governments have pledged far more land for forestation than the models consider suitable for tree planting.

For example, Ethiopia has committed to reforesting 10.2 million hectares but the study finds only 0.5 million hectares are actually suitable. Similar gaps are apparent in Cameroon, South Africa and other countries.

The gap arises because the new study only counts land that is naturally suited to forests, based on climate soils and existing vegetation. Many government pledges, by contrast, include ecosystems such as savannas or grasslands.
Across Africa, 70 million hectares of land committed to tree planting – an area the size of France – fall into this category.

Savannas are constrained by low rainfall, and trees are kept in check by hungry herbivores and frequent fires. The height that a woody plant in a savanna needs to reach to survive the regular burning is called the “fire trap” for a reason, as many saplings do not make it above that threshold. Planting forests here is not only unlikely to succeed, it also risks damaging unique ecosystems and biodiversity. And crucially, replacing natural savanna with plantations is not equivalent to restoring or protecting a tropical rainforest.

One limitation is that the new study did not include agroforestry – integrating trees into farmland – which could add more potential for carbon storage. But the bigger lesson from news that the climate potential of forests may have been exaggerated is that planting trees should complement, not replace, rapid emissions cuts.

To make the most of forests, the world needs better science-based guidelines for where trees will thrive, and stronger commitments to act quickly. The clock is ticking.

Can meat really protect against cancer-related deaths, as a new study indicates?

Source: The Conversation – UK – By Ahmed Elbediwy, Senior Lecturer in Clinical Biochemistry / Cancer Biology, Kingston University

For years, health authorities have warned against red meat consumption, with the World Health Organization’s cancer research arm classifying it as “probably carcinogenic to humans”. But a controversial new study challenges that position, suggesting that animal protein might protect against cancer deaths rather than cause them.

The International Agency for Research on Cancer (IARC), part of the WHO, has long classified red meat, including beef, pork, lamb and mutton, as probably carcinogenic. And processed meats such as bacon and sausages are classified as definite carcinogens. This judgment reflects multiple studies linking red meat to colorectal cancer, forming the basis of dietary advice to limit intake.

Yet the new research by Canada’s McMaster University suggests the opposite: that people who consume more animal protein may actually have lower cancer mortality rates. But, before you rush out to buy a pack of sausages, there are some important points you should note.

The study’s methods contain important nuances that complicate its headline-grabbing conclusions. Rather than examining red meat specifically, the researchers analysed consumption of “animal protein”, a broad category that includes red meat, poultry, fish, eggs and dairy products. This distinction matters significantly because fish, particularly oily varieties such as mackerel and sardines, are associated with being cancer-protective.

By grouping all animal proteins together, the study may have captured the protective effects of fish and certain dairy products rather than proving the safety of red meat.

Dairy products themselves present a complex picture in cancer research. Some studies suggest they reduce colorectal cancer risk while potentially increasing prostate cancer risk. This mixed evidence underscores how the broad “animal protein” category obscures important distinctions between different food types.

The study, which was funded by the National Cattlemen’s Beef Association, America’s primary beef industry lobbying group, contains several other limitations. Crucially, the researchers didn’t distinguish between processed and unprocessed meats – a distinction that countless studies have shown to be vital.

Processed meats such as bacon, sausages and deli meats consistently show higher cancer risks than fresh, unprocessed cuts. Additionally, the research didn’t examine specific cancer types, making it impossible to determine whether the protective effects apply broadly or to particular cancers.

Interestingly, the study also examined plant proteins, including legumes, nuts and soy products such as tofu, and found they had no strong protective effect against dying of cancer. This finding contradicts previous research suggesting that plant proteins are linked to decreased cancer risk, adding another layer of complexity to an already confusing picture.

These findings don’t diminish the established health benefits of plant-based foods, which provide fibre, antioxidants and other compounds associated with reduced disease risk.

Not a green light

Even if the study’s conclusions about animal protein prove accurate, the study shouldn’t be interpreted as a green light for unlimited meat consumption. Excessive red meat intake remains linked to other serious health conditions, including heart disease and diabetes. The key lies in moderation and balance.

The conflicting research highlights the complexity of nutrition science, where isolating the effects of individual foods proves remarkably difficult. People don’t eat single nutrients in isolation – they consume complex combinations of foods as part of broader lifestyle patterns. It’s more important to focus on overall dietary patterns rather than fixating on individual foods.

A balanced plate approach, featuring a variety of protein sources, plenty of vegetables and fruits, and minimally processed foods, remains the most evidence-based path to optimal health.

While this latest study adds a new dimension to the meat debate, it’s unlikely to be the final word. As nutrition science continues to evolve, the most prudent approach remains the least dramatic: moderation, variety and balance in all things.

The west’s image of Vladimir Putin as an untrustworthy ‘monster’ is getting in the way of peace in Ukraine

Source: The Conversation – UK – By Francesco Rigoli, Reader in Psychology, City St George’s, University of London

Ukraine and its western allies are losing ground in the war against Russia. A possible Russian victory will be costly and is likely to be followed by years of exhausting low-intensity conflict while the country remains ostracised from the western economic system.

So, all parties fighting in Ukraine need badly a diplomatic solution. The meeting between Trump and Putin in Alaska has reopened this possibility. Yet many in the west remain wary that a viable solution can be reached. What motivates this scepticism? An important reason is that many western leaders simply don’t trust the Russian president, Vladimir Putin. They believe that whatever agreement is reached to end the fighting in Ukraine, Putin will breach it when this suits his interests.

Many western analysts fear that stopping the fight in Ukraine will allow Russia to replenish its offensive capabilities to be better placed to relaunch an attack soon. Meanwhile, many reason that continuing the war will weaken Russia while giving European countries the time to rearm, boosting their deterrent power and – in the eventuality that Russia launches attacks on other European countries – allowing Europe to react energetically.

These strategic considerations are important. Yet there are also profound emotional factors that lead many politicians and journalists – backed by big chunks of public opinion – to be wary or sceptical of any deal with Putin.

This attitude stems from the moral principle that compromising with an evil person is deeply wrong. Putin is perceived by many in the west as the quintessential incarnation of a bloodthirsty tyrant. The former USA president Joe Biden repeatedly referred to Putin in these terms, calling him variously a “monster”, a “crazy SOB”, and – even before the Russian invasion of Ukraine – a “killer” with “no soul”. European leaders have often echoed this judgement, like the French president, Emmanuel Macron, who recently called Putin a “predator” and an “ogre at our doorsteps”.

As psychological research has shown, the prospect of striking a deal with people deemed to be evil often triggers strong moral repulsion. Any potential compromise is perceived as morally disgusting, since it signals that appeasers are willing to sacrifice their moral integrity in exchange for material benefits. Most recently, this moral stance has driven various commentators to blame the US president, Donald Trump, for giving Putin a red-carpet welcome to their recent summit in Alaska.

It is common to draw a historical parallel between Vladimir Putin and Adolf Hitler. The option of compromising with Hitler, as Europe’s leading statesmen did in the now notorious Munich conference in 1938, is regarded today not only as strategically naïve, but also as morally deplorable.

Incarnations of evil such as Hitler, the argument goes, do not leave space for compromise – only for complete destruction and unconditional surrender. Since, according to this view, Putin and Hitler are of the same stock, the only acceptable result for the war in Ukraine is Putin’s unconditional surrender – or something as close as possible to this outcome.

Both sides need to listen

The moral drive to avoid compromises with evil people is part of human nature. Yet rigidly applying this principle to geopolitical conflicts like the war in Ukraine is dangerous. A well-established rule in the conflict resolution literature is that the path to peace requires that the opposing parties abandon rigid views of good and evil and accept that the adversary’s perspective is at least worth listening to. So far, the west has made little effort in this direction when it comes to Russia’s motives for making war on Ukraine.

It’s hard to see what the west expect by continuing to paint Putin as some kind of devil, while Russian elites, for their part, express similar views about western leaders. Something akin to the endemic conflict between Palestinians and Israeli is a worrying, but not unrealistic, scenario. In that case, too, many view the enemy as an incarnation of evil to be annihilated, portraying any compromise as morally intolerable.

The west’s stance on this, to some extent, may even be a self-fulfilling prophecy. Depicting Putin as Hitler risks being interpreted by Russians as signalling that, for westerners, destroying Putin is the only option available. This may lead Russians to conclude that the west is not serious about diplomacy and that, if an agreement is struck, the west will continue to harbour the desire to smash Putin, thus being ready to breach the agreement at will.

Russian leaders may in turn downplay diplomacy and be ready to cheat if any agreement emerges. So, it cannot be ruled out that, in part, Putin is devious on Ukraine because he sees how the west is accustomed to portraying him.

The west can rightly blame Putin for his intransigent approach. But if Putin has left little room for reconciliation, the west has not done much in this respect either. Western leaders should consider whether adopting a more nuanced portrayal of Putin in their public discourse could help. Abandoning an excessively moralistic attitude towards Putin would signal to Russians that the west believes that an agreement is possible and is committed to respect it.

This, in turn, may encourage Russians to follow the same path. While building mutual trust is going to be hard and take time, it may be the only viable solution for an enduring peace in Ukraine and Europe. Building mutual trust will require to acknowledge that reaching an agreement with Putin is not morally wrong.

Do weighted blankets work for anxiety? Here’s what the evidence shows

Source: The Conversation – UK – By Craig Jackson, Professor of Occupational Health Psychology, Birmingham City University

Victoria Antre/Shutterstock.com

They have been promoted as a remedy for anxiety and sleeplessness, with celebrities and influencers swearing by their calming effects. Weighted blankets – heavy throws filled with glass beads or plastic pellets – have gone from a niche therapeutic tool to a mainstream wellness must-have, promising better sleep and reduced stress for anyone struggling to unwind.

But do they deliver on these bold claims, or are we simply paying premium prices for an expensive placebo?

Occupational therapists have used weighted blankets since the 1970s to help children with autism and adults with sensory processing disorders. They became commercially available in the 1990s, but remained largely within special needs communities.

That changed dramatically in recent years when companies began targeting what they call the “casually anxious” – essentially, anyone struggling with modern life’s stresses. The marketing worked: Time magazine even named the weighted blanket one of the top 50 “inventions” of 2018.

The concept behind weighted blankets is appealingly simple. Typically weighing between two and 13 kilograms (experts recommend choosing one that’s 10% of your body weight), they use what occupational therapists call “deep pressure stimulation”. The gentle, even pressure across your body mimics the sensation of being held or hugged.

What the science says

The research picture is more nuanced than the marketing suggests. Several studies do show promising results, but with important qualifications.

A study of 120 psychiatric outpatients found that weighted blankets improved insomnia symptoms over four weeks in people with major depression, bipolar disorder, anxiety and ADHD. The researchers concluded they were “a safe and effective intervention for insomnia in patients with some mental health disorders”.

Smaller studies have shown similar patterns. One found that 63% of adults reported lower anxiety after just five minutes under a weighted blanket, while another study of psychiatric inpatients found 60% experienced reduced anxiety during their hospital stay.

However, these studies all focused on people with diagnosed mental health conditions, not the general population that companies are now targeting.

This is where the science diverges from the marketing: reviews of the research consistently show that benefits for healthy people are much harder to prove. While weighted blankets may help people with clinical anxiety or sleep disorders, there’s insufficient evidence that they benefit casual users without existing mental health conditions.

Also, about half the research on weighted blankets doesn’t meet quality standards for robust scientific evidence – a significant problem given the confident health claims found on product websites and glowing reviews in lifestyle magazines.

Who might benefit?

This doesn’t mean weighted blankets are entirely useless for healthy people. Shift workers, who must sleep during daylight hours when their brains are naturally alert, might find them helpful for combating the known health effects of irregular schedules. Healthcare workers, firefighters and pilots who rely on strategic power naps could benefit from faster sleep onset.

The placebo effect also shouldn’t be dismissed. If a weighted blanket helps you feel calmer and sleep better, even if the mechanism isn’t what manufacturers claim, that’s still a positive outcome, provided you understand what you’re buying.

Weighted blankets do carry some risks. They shouldn’t be used by anyone who cannot easily move beneath their weight, including young children. People with diabetes, asthma, sleep apnoea, COPD, circulation problems, high blood pressure or claustrophobia should consult their GP before opting to use one.

No studies have reported serious harms, but common sense suggests checking with a healthcare provider if you have underlying health conditions.

As a low-risk intervention that might complement good sleep hygiene and regular sleep cycles, weighted blankets aren’t inherently problematic. The issue lies in overselling their capabilities.

If you’re considering buying one, be realistic about your expectations. You’re not buying a miracle cure for modern anxiety but rather a potentially comforting sleep aid that might help you feel more settled at bedtime. For many people struggling with sleep, that gentle pressure and sense of security could be worth the investment, even if the science behind it isn’t quite as solid as the marketing suggests.

The real question isn’t whether weighted blankets work, but whether they work for you, and whether the premium price is justified for what might ultimately be an expensive hug.

Different day, same problems? Why it’s a bad idea to rush into solutions for tricky work issues

Source: The Conversation – UK – By Poornika Ananth, Assistant Professor in Strategy and Organisations, School of Management, University of Bath

Regardless of how you spent the final days of summer, the return to work can mean coming face to face once again with any sticky problems you pushed aside previously. Now though, they’re looming and demanding fresh solutions.

This may be a good time to try something different. Whatever the nature of the problems that come with your job – production or staffing issues, a difficult product launch or disgruntled customers – instead of focusing all your efforts on coming up with solutions, it may be helpful to spend some time understanding the problems better.

As Albert Einstein is quoted as saying: “If I had an hour to solve a problem, I’d spend 55 minutes thinking about the problem and five minutes thinking about solutions.” But why is it so important not to simply jump to quick solutions?

Similarly, scholars who have studied problem-solving have found that workplace problems can be complex and ill-defined, and their underlying causes can be difficult to determine at first glance. In these circumstances, the solutions we develop are based on surface-level understanding or assumptions. As such, they may do little to address the true problem – and could even create new issues further down the line.

For instance, if you are struggling with a tricky product launch, it might look like the issue is a flaw in the item. But in reality the problem could be weak distribution or poor marketing reach. Clearly, focusing on the product design in this case is unlikely to resolve the issue.

To get through this, it is important to develop a more thorough understanding of the problem. This is known in management studies as a “problem representation” – that is, a simplified model of the problem, including the symptoms that characterise it as well as the root causes that explain it.

My colleagues and I have reviewed the literature on problem representations. Our research, published in the Journal of Management, has found key insights about how best they can iron out problems in the workplace.

Take your time

The first and most important insight is that representing complex problems is not a one-time event, but a process that involves three distinct but overlapping steps. The first step is “problem finding”, which involves recognising early or obvious symptoms that point to the existence of a problem. This could be missing a production deadline or a sales target, for example.

The second step is “problem framing”, which involves looking out for and identifying other related symptoms. During this step you may find that in addition to missing your production deadlines your colleagues have also been working more overtime. Or it could be that you are missing sales targets despite positive reactions from focus group tests of the product. To get this more comprehensive picture you will probably need the perspectives of people at various levels of the organisation.

The final stage is “problem formulating”, which is where you work out the root causes that underlie and explain the symptoms. Here workers need to truly understand why they arose in the first place. The key is to ensure that the root causes really do represent the spectrum of symptoms. This may help you understand, for instance, that production issues are due to problems with a new part. Alternatively, a sales issue could be because the marketing channels are not reaching the right consumers.

Our review also found that a problem representation can help with solving the issue in more than one way. Crucially, getting to the root causes can give rise to solutions that target the problem more effectively and completely. It can also enhance the creativity behind problem-solving by getting people to break away from obvious, surface-level answers.

An additional benefit that we uncovered in our review is that developing a problem representation can help with implementing the solutions. We found that there are two reasons for this.

First, there may be fewer snags or glitches that arise during implementation if the solution is more considered, and more relevant to the problem. Second, people may be more invested in implementing the solution if they have taken the time to consider the problem and believe that the solution can address it for them in the long term.

But our review also revealed that representing a problem can be a challenging process, fraught with traps and issues of its own. These could be participants not properly understanding the process, cognitive biases – particularly solution bias (the tendency to jump to solutions) – and bad actors who claim to be engaged in the process but end up derailing it.

However, if done well, this process can really help you tackle problems and develop and implement genuinely useful solutions. And this approach can help with problems at all kinds of workplaces and in all kinds of roles.

Play for Today is back – nine ways Channel 5 can make it as successful as the original

Source: The Conversation – UK – By Katie Crosson, Postdoctoral Research Associate (Curation), University of Exeter

Between 1970 and 1984, BBC1’s experimental drama strand Play for Today created what is now regarded as classic British drama. It launched myriad acting careers and showcased high-calibre writing in plays such as Mike Leigh’s Abigail’s Party and Blue Remembered Hills, Dennis Potter’s acclaimed play about lost youth. It was often challenging, often radical and always unpredictable, rotating directors, producers and writers each week to create unique one-off episodes.

The series covered a huge range of subject matter, across different genres and styles, and sought to reveal truths about contemporary life. By the mid-1980s, the BBC was reluctant to continue taking costly chances on new talent each week in an era of increasing competition, and Play for Today was canned.

Now, in 2025, it’s coming back. Channel 5 recently announced the return of the series, emphasising that the new Play for Today will provide a space to experiment for emerging creative talent, particularly those from low-income backgrounds. This development is welcome in an industry that fails to embrace working-class entrants.

In the chasm between 1984 and 2025, the structure of British society has changed beyond recognition. The class system itself has shape-shifted numerous times, with the erosion of many working-class trades and the increasing precarity of middle-class professions, with many affected by steep increases in the cost of living, high student debt and a housing crisis. All the while, the UK’s super-rich are richer than ever and inequalities are rising.

All of which increase the urgency for a strand like Play for Today, willing to respond to these issues. And while I remain hopeful that this new Channel 5 incarnation can be a success, my research into the original has informed nine non-negotiables required to fulfil its goals and earn the Play for Today name.

1. Represent resistance

Play for Today didn’t only amplify unheard voices, it also portrayed under-represented struggles. From female strikers in Leeds United! (1974) to occupiers on a development site during a rent-hike in United Kingdom (1981), Play for Today didn’t present characters as helpless victims, but people with agency engaged in resistance.

Channel 5 claims it wants to cover “thornier issues”. If it is serious about this, it could offer a unique space to explore marginalised voices, such as youth organisers involved in the ongoing fight for trans rights, and those speaking out against the alleged genocide in Palestine experiencing censorship and criminalisation.

2. Encourage critique

Play for Today critiqued the system, not just individuals. Destiny (1978) was an honest portrayal of the top-down, predatory nature of fascism. Its speech about “making the country great again” lay at the centre of an examination of the links between landlords and organisations like the National Front.

The Sin Bin (1981) offered a sobering portrayal of the lives of inmates in prison for the very worst of crimes. Play for Today asked its audience to extend their empathy, asking what we are willing to accept in the name of justice, and whether the criminal legal system is fit for purpose.

3. Be specific

The series represented specific times, towns and trades in detail. The lives of people in Hull in Land of Green Ginger (1973) and Morecambe in Sunset Across the Bay (1975) were examined without compromising their uniqueness by trying to universalise characters’ experiences.

The Bevellers (1974) and Not For The Likes of Us (1980) were built around portrayals of manual labour and working in a cinema. Far from making the programme inaccessible or irrelevant, millions tuned in each week: Play for Today was engaging precisely because it depicted lives and livelihoods little seen on screen.

4. Rotate creators

Held together by little more than a commitment to responding to the present moment, it is an essential feature of Play for Today that writers, actors, directors and producers rotate regularly, to ensure a variety of perspectives.

5. Foster innovation

It is important that Channel 5 doesn’t see the programme’s focus on social truths as something at odds with experimenting with form. From the raucous comedy of Bar Mitzvah Boy (1976) to the folk-horror of Penda’s Fen (1974), the agit-prop filmed theatre of The Cheviot, the Stag and the Black, Black Oil (1974) and the surrealism of The After Dinner Joke (1978), Play for Today was never confined to one stylistic box.

These examples deviate from the predictable style British audiences appear to be tiring of – a state of affairs made clear by the unprecedented appetite for the mini-series Adolescence, in which each episode was shot in one long single take.

6. Ensure creative freedom

If the new Play for Today is to be as distinctive and bold as its namesake, creators must be given proper creative control over what they’re making. Creativity flourished on the original series because creative control was the norm for these drama productions.

7. Offer a real vision of the working class

Ladies (1980) focused on the lives of female department-store workers spanning different ages and ethnicities. The Spongers (1978) explored the reality of living with disability in poverty, and Even Solomon (1979) featured the first transgender protagonist on British television. At its best, Play for Today portrayed a spectrum of working-class characters as diverse as real life, and it can again.

8. Show emotion

Play for Today presented issues in ways that elicited emotional as well as intellectual responses. Rocky Marciano is Dead (1976) focused on the importance of boxing to different communities, tenderly exploring the strained relationship between an ageing boxer and a squatter next door. At a time where social division is rife, we could benefit from being moved to look at the world and people around us in ways that promote understanding and empathy.

9. Be free to fail

Play for Today proved it’s possible to have both quality and quantity, but only through embracing failure. With 316 episodes made by different people, not all of Play for Today was pioneering. The same freedom that granted Play for Today its huge successes also granted its failures. The team behind Channel 5’s Play for Today would do well to accept that we cannot have one without the other, but look to the original, and enthusiastically and wholeheartedly take the risk.

What’s the link between an exploding star, climate change and human evolution? Francis Thackeray, who has researched ancient environments and fossils for many years, sets out his ideas about what happened in the distant past – with enormous consequences.

Global cooling that happened millions of years ago was thought to be the result of ocean currents. He suggests instead it could have been due to the impacts of remnants of supernovae. The timing of supernovae, climate changes and species evolution coincides.

What is your supernova hypothesis?

My hypothesis is that remnants of a supernova – an exploding star – had an impact on the Earth’s past climate, causing global cooling, between 3 million and 2.6 million years ago and that this indirectly affected the evolution of hominins (ancient relatives of humans).

How does this change assumptions held until now?

It has been considered by some that global cooling in the Plio-Pleistocene might have been due to changes in ocean currents. This may well be correct to some extent, but I think that the supernova hypothesis needs to be explored.

It’s super-exciting to think that our evolution may to some extent be associated with supernovae as part of our dynamic universe.

How did you come to your supernova hypothesis?

Supernovae include stars which are extremely massive (as much as five times the mass of our Sun) and have reached the end of their stellar evolution. These explosions are rare. On average, within our galaxy (the Milky Way), only one or two per century are visible from Earth as temporary bright stars.

As a result of such explosions, material is expelled into outer space at almost the speed of light. Chemical elements are formed, including a kind of iron (the element Fe) known as isotope Fe-60. It has 26 protons and as many as 34 neutrons.

Traces of Fe-60 iron isotopes from supernovae within the last ten million years have been discovered on Earth in marine deposits such as those drilled in cores in the east Indian Ocean.

The deep-sea deposits with Fe-60 can be dated using radioactive elements which decay at a known rate. This is called radiometric dating.

There was a regular increase in extremely small traces of Fe-60 for the period between 3 million and 2.6 million years ago. We know this from data published by Anton Wallner and his colleagues. Since this is a linear trend I have been able to extrapolate back to 3.3 million years when initial cosmic rays may have first hit Earth. I have proposed in the Quest magazine that this initial cosmic impact correlates with a major glaciation (cooling) event called M2 in an otherwise warm period.

A “near earth” supernova could have produced cosmic rays (radiation from outer space) which might have caused a reduction in the earth’s ozone layer. Increased cloud cover associated with cosmic radiation could have been a factor related to changes in global climate. Specifically, the change would have been global cooling.

This cooling would have affected the distribution and abundance of plant species, in turn affecting that of animals dependent on such vegetation.

What potential new insights does the hypothesis give us into human evolution?

Populations of Australopithecus may have been indirectly affected by the decrease in temperature.

Australopithecus is the genus name for distant human relatives which lived in Africa in geological periods called the Pliocene and Pleistocene. The boundary between these time intervals is 2.58 million years ago. At that time, certain species went extinct. The period coincides closely with the maximum of Fe-60 in marine deposits and a change in Earth’s magnetic field.

The first fossil of Australopithecus to be described, 100 years ago, was placed by the palaeontologist Raymond Dart in a species called A. africanus. Dubbed the “Taung Child”, it was discovered in South Africa. Its biochronological age, recently based on mathematical analyses of tooth dimensions, is about 2.6 million years – at the Plio-Pleistocene boundary.

It cannot be concluded that the death of the Taung Child was directly caused by a supernova. This would be far-fetched. There is in fact evidence that this individual, about 3 years old, was killed by an eagle.

However, it is plausible to suggest that in Africa, in the Plio-Pleistocene, populations of Australopithecus were affected by a decrease in temperature affecting the distribution and abundance of vegetation and the animals dependent on it.

Recently, a new species of Australopithecus (as yet not named, from Ledi-Geraru) has been discovered in Ethiopia, in deposits dated at about 2.6 million years ago – also the time of the maximum in Fe-60 in deep-sea deposits.

The appearance of the genus Homo is close to the Plio-Pleistocene boundary, reflected by fossils reported recently by Brian Villmoare and his colleagues and well dated at about 2.8 million years ago. The origin of Homo may relate to changes in temperature and associated changes in habitat, as recognised five decades ago by South African palaeontologists Elisabeth Vrba and Bob Brain, although they emphasised a date of 2.5 million years ago.

Is it possible that cosmic radiation stimulated genetic changes?

I have been told by my peers that I am inclined to think “out of the box”. Well, in this case I would like to propose a “hominoid mutation hypothesis”. The hypothesis states that the speciation of hominoids (including human ancestors and those of chimpanzees and gorillas) was to some extent associated with mutations and genetic variability caused by cosmic rays.

It is interesting to consider the possibility that the origin of our genus Homo relates in part to cosmic radiation. Going deeper back in time, Henrik Svensmark has demonstrated that there is a correlation between supernova frequency and speciation (increased biodiversity associated with the evolution of new species), for the last 500 million years (the Phanerozoic period). I think it’s entirely possible that one important cause behind this correlation was the mutagenic (mutation-causing) effect of cosmic rays on DNA, such that rates of speciation exceeded those of extinction.

In hominoids, cosmic rays could have contributed not only to global cooling but also to genetic changes, with subsequent anatomical (morphological) changes related to speciation.

If we go back to about 7 million years ago (when Fe-60 again reflects supernova activity), we would expect to find fossils that are close to a common ancestor for chimpanzees and humans. In terms of the hominoid mutation hypothesis, the split could have been associated with cosmic radiation. One hominoid species about 7 million years old is Sahelanthropus (discovered by Michel Brunet in Chad). In my opinion this species is very close to the common ancestor for Homo sapiens (us) and chimps.

DRC’s latest peace deal is breaking down and it isn’t the first – what’s being done wrong

Source: The Conversation – Africa (2) – By Kristof Titeca, Professor in International Development, University of Antwerp

A series of peace initiatives since 2021 have sought to address the escalation of conflict in eastern Democratic Republic of Congo (DRC) following a renewed offensive from the M23 rebel group.

The origins of this crisis go back to the First Congo War in 1996. Since then, the intensity of conflict in eastern DRC has ebbed and surged. The current M23 offensive represents one of its most violent phases.

Over nearly three decades, numerous peace efforts have been undertaken, yet neither local, regional nor international interventions have succeeded in bringing lasting stability. Crucially, they have failed to tackle the broader dynamics that perpetuate violence in the country’s mineral-rich east, where at least 120 armed groups are estimated to be active.

These recent efforts include the Nairobi process launched in April 2022 by the East African Community, and the Luanda process in June of the same year, launched by Angolan president João Lourenço.

The East African Community deployed its regional force to the DRC in November 2022. This was followed by the Southern African Development Community deploying troops in December 2023. These troops withdrew in 2023 and 2025, respectively.

More recently, there have been peace talks in Doha, which started after a meeting between the presidents of Congo and Rwanda in March 2025. The US mediated in Washington from April 2025.

The conflict has continued to escalate. More than 7.8 million people are now internally displaced in eastern DRC. Another 28 million people are facing food insecurity, including nearly four million at emergency levels.

Why have peace processes failed to deliver stability, and what could be done to strengthen them?

I have studied the dynamics of conflict in central Africa for decades, and in my view, the persistence of conflict in DRC’s eastern region isn’t due to a lack of peace initiatives. I argue that some initiatives suffer from flawed design, others from difficult implementation, and some from a combination of both.

Deep mistrust, stalled commitments, the exclusion of key actors, fragmented mediation efforts, an overemphasis on economic incentives, and weak domestic legitimacy have all undermined progress.

Ideally, peace processes would address these shortcomings comprehensively and lay the foundations for lasting stability.

But ideal conditions rarely exist.

The challenge, therefore, is to use sustained diplomacy to make the current imperfect frameworks work more effectively, while gradually building the trust and inclusivity needed for more durable peace.

What’s gone wrong

1. Deep mistrust between the parties

Peace processes since 2021 have focused on negotiating peace between the DRC government, M23 representatives (and their political wing Alliance Fleuve Congo) and the Rwandan government. The UN and many others have shown that Rwanda has been supporting the M23, a claim Kigali repeatedly denies.

At the heart of the failures of these processes lies a profound lack of trust. Relations between Kinshasa, M23 and Kigali are marked by hostility, mutual suspicion and broken promises.

Moreover, M23, Alliance Fleuve Congo and Rwanda cannot be treated as interchangeable actors. Among these actors, differences remain over the ultimate objectives of the rebellion – whether to march on Kinshasa, secure control over key territories in the east, or build influence through Congolese state structures versus a de facto separate administration.

Continued atrocities on the ground reinforce distrust. Recent reports from the UN, Human Rights Watch and Amnesty International document continued killings and summary executions of Congolese civilians by M23 rebels with Rwandan backing, raising concerns of ethnic cleansing. These have happened alongside abuses by Congolese forces and allied militias (grouped as Wazalendo).

2. Poor implementation measures

Because of this mistrust, parties are reluctant to take the first step in implementing agreements. The 19 July 2025 Doha Declaration of Principles, for example, committed both sides to prisoner exchanges and the restoration of state authority in rebel-held zones. Yet, Kinshasa refused to exchange prisoners before a final settlement, a condition M23 saw as essential.

3. Failing to include all regional actors

The war in eastern DRC involves multiple neighbouring states. Uganda, in particular, has a significant military presence and shares Rwanda’s concerns and motivations: both see the area as a security threat and an economic opportunity, especially through gold exports and cross-border trade. Yet, Uganda has been excluded from some negotiations.

In early August 2025, African states announced they would merge mediation structures by the East African Community, the Southern African Development Community and the African Union into one solidified process led by the African Union. This could potentially bring in these regional actors, particularly Uganda.

4. Duplication and fragmentation of initiatives

A recurring problem since the renewed outbreak of conflict in 2021 has been the proliferation of parallel and overlapping peace initiatives, involving different actors, and not necessarily bringing coherence.

5. The role and limits of external pressure

The success of negotiations to some extent depends on how much diplomatic bandwidth the mediating actors want to spend.

In the current context, US pressure is key. And indeed, in light of renewed fighting in mid-August 2025, the US has released a number of statements and sanctions against the parties involved – mostly M23. Yet, expectations of heavy-handed US intervention, including the unrealistic notion of American “boots on the ground”, have created disappointment among a number of actors, particularly in the DRC.

6. Economic incentives alone are insufficient

The Washington process placed heavy emphasis on promoting trade with the US, presenting economic growth as a pathway to stability. But peace requires more than economic deals. This approach risks reducing a multidimensional conflict – rooted in political, security and social grievances – to a question of markets. This risks prioritising US economic interests rather than addressing local realities.

7. Weak internal legitimacy

Finally, the legitimacy of the current peace deals within the DRC remains contested. The intensifying conflict has coincided with mounting domestic criticism of President Felix Tshisekedi, whose authority was undermined by his inability to resolve the violence. Agreements have been criticised by Congolese civil society as externally driven and insufficiently inclusive. They have not been ratified by parliament nor have they involved civil society or grassroots actors.

What needs to change?

Eastern DRC remains mired in conflict despite peace initiatives. Broken promises, weak implementation, and deep mistrust keep progress at bay. Economic incentives alone can’t solve a crisis rooted in politics, security and social grievances.

Outside powers can only apply leverage. Durable peace must be negotiated and owned by the parties themselves. And without broader buy-in, peace processes risk functioning merely as cooling-off mechanisms, not genuine pathways toward resolution.
