The wildflowers of Britain include all manner of treasures – yet many people are only aware of a few, such as bluebells and foxgloves. A lot of its other flora are rare because of Britain’s location at the northern, western or even southern edges of their natural geographic – and hence climatic – ranges.

In fact, Britain has over 1,000 native species of wildflower, including 50 kinds of orchid, a few species like sundew that use sticky tentacles to eat insects, and others such as toothwort that live as parasites, plugging their roots into other plants to suck on their sap like botanical mosquitoes. There are even a few species, such as the ghost and bird’s-nest orchids, that extort all their food from soil fungi.

Many people think of plants as nice-looking greens. Essential for clean air, yes, but simple organisms. A step change in research is shaking up the way scientists think about plants: they are far more complex and more like us than you might imagine. This blossoming field of science is too delightful to do it justice in one or two stories.

This story is part of a series, Plant Curious, exploring scientific studies that challenge the way you view plantlife.

Losing weight is hard. Anyone who has tried to lose weight and keep it off will describe how difficult it can be. If your pet is a little more rotund than is healthy, then helping them regain and retain their waistline can be even trickier.

Drugs such as Ozempic (the brand name for the drug semaglutide) and Mounjaro (brand name for tirzepatide), both originally intended for treating type 2 diabetes in humans, have become increasingly used to support human weight loss. Given that estimates suggest that at least 50% of dogs and cats weighed at the vets are overweight, it’s unsurprising that the future potential to use drugs to support pet weight loss is now being explored.

It’s important to note that these weight management drugs are not currently in use for our pets, but it’s undeniable that pet obesity is a growing concern, and pharmaceutical companies are looking for solutions.

Just like us, carrying excess weight is associated with several health conditions for our pets, including osteoarthritis, inflammatory conditions, metabolic disorders and even shorter lives. This means that excess body weight is a significant health and welfare concern for our pets and might even be linked to our own expanding waistlines.

Unfortunately, our pets have a number of lifestyle challenges that can make weight gain more likely. Food that is tasty, freely available, highly digestible and high in calories means it is easy for our pets to eat more than they need. Combined with the use of frequent food training rewards and even accidental or guilt-based overfeeding, pets can quickly gain weight, which is then often difficult to lose.

Spaying and neutering have been very effective at reducing pet overpopulation and lowering the risk of some health problems like mammary tumours. However, these procedures can also make pets more likely to become overweight. To help prevent this, owners usually need to adjust their pets’ diets after surgery – most often by slightly reducing food portions and keeping track of their pets’ weight and body condition.

Some animals are more likely to gain weight because of their genetics, and this tendency has been unintentionally reinforced during domestication. Labrador retrievers, often called “foodies”, are a good example. Research shows that many Labs carry a gene mutation that affects an appetite-regulating molecule called pro-opiomelanocortin. Dogs with the mutation are more food-driven and more likely to gain weight than dogs without it.

Limited exercise is another big risk factor for weight gain. Many pets spend most of their time indoors or in the garden, which reduces their activity and energy use. Regular walking is good for dogs and their owners.

However, exercise alone won’t necessarily keep your pet lean. So, what can you do without the use of weight-loss drugs to help your pet?

Helping your pet keep a healthy weight naturally

Knowing what a healthy weight looks like for your pet is essential. One of the easiest tools for this is body condition scoring. Instead of just looking at the number on the scales, body condition scoring involves feeling your pet’s ribs, waist and tummy to check whether they’re too thin, too heavy or just right.

When used alongside regular weigh-ins, it gives you a clear picture of your pet’s overall health and helps you spot small changes early. Acting quickly on slight weight gain or loss – through diet, exercise, or a vet check – can make a big difference in keeping your pet fit and well.

Keeping active with your pet can help you both stay at a healthy weight. Playing games, adding fun activities, or just making sure your pet moves more each day are simple ways to support weight loss and keep it off in the long run.

What your pet eats is just as important as exercise when it comes to a healthy weight. A diet lower in calories to support steady weight loss is helpful for otherwise healthy pets. This can be done with foods that have less fat, moderate protein and more fibre. Some nutrients, like carnitine, which is often included in weight management diets, may also help the body use energy more effectively.

You can also look for low-calorie swaps that your pet enjoys. For example, many dogs love carrots and cucumbers as healthier treats.

If you are concerned about your pet’s weight, do seek veterinary advice and support. Keep records of their body weight, body condition, overall health, activity and even food intake. This can help you see where there might be easy wins for improving their health, wellbeing and even lifespan.

The choice is clear: rather than waiting for pharmaceutical solutions, we already have the tools we need to help our pets live their healthiest, happiest lives. The question isn’t whether we can help our pets maintain a healthy weight naturally – it’s whether we’re willing to make the commitment to do so.

In Ukrainian dictionaries, the word “surzhyk” originally referred to a mix of grains – rye, wheat, barley and oats – or to flour made from a blend of these that was considered of lower quality. But its meaning morphed to mean a mixed or “impure” language – and today it refers to a blend of Ukrainian and Russian used by millions in Ukraine.

Often stigmatised in the past as a marker of rural backwardness, poor education or simply ignorance of Ukraine’s literary norms, the status of the Surzhyk language is now being reconsidered in wartime – not as a threat to Ukrainian identity, but as a way for native Russian speakers to communicate in a way that is more socially acceptable in a country at war with Russia.

Since the full-scale invasion of 2022, people in some central and eastern areas of Ukraine who might have primarily spoken Russian have been switching to Ukrainian, particularly in public. These are people who would have understood and occasionally used Surzhyk, but would have seen it as a form of Ukrainian “pidgin” – not to be used in formal situations. But now, it’s increasingly being used and any stigma that might have attached to it is slowly disappearing.

There has been debate about whether it’s a language in its own right, or a dialect or even slang. Most Ukrainian linguists tend to refer to it in English as an “idiom”. But it’s important to note that Surzhyk varies by region and is constantly evolving.

In the 1930s, it was heavily Russianised, reflecting Soviet language policies. More recently, after decades of Ukrainian revival, it has tilted in the other direction towards Ukrainian. And other influences are creeping in, especially from English. Words like “булінг” (buling, like the English “bullying”) and “донатити” (donatyty, meaning “to donate”) are slipping into everyday speech, showing how Surzhyk mirrors society’s shifting horizons.

But it is also a product of trauma and necessity. As Ukrainian writer Larissa Nitsoy notes, Ukrainians survived genocide – and they also survived linguicide. During the Soviet era, Russia made strenuous efforts to eradicate the Ukrainian language, punishing – often executing – those who spoke, wrote and taught in Ukrainian. To survive, they adapted.

Later, Surzhyk continued as a practical tool of social mobility. As Ukrainian-speaking villagers moved to Russian-dominated big cities in Ukraine for work or education, they adopted a hybrid idiom to “pass” as local. Laada Bilaniuk, a US-based anthropologist, calls this “urbanised-peasant Surzhyk” – a way of mimicking Russian without abandoning one’s Ukrainian linguistic roots.

In this sense, Surzhyk was both a survival strategy under Russian colonial rule, and an adaptation to urbanisation.

How widespread is Surzhyk?

In 2003, the Kyiv International Institute of Sociology (KIIS) estimated between 11% and 18% of Ukrainians spoke or wrote in Surzhyk – roughly one in seven people at the time. A more recent study of 104 students of the National Transport University in Kyiv in 2024 found that more than half of respondents (51%) admitted using some form of Surzhyk at home, and nearly one in five used it in messages with friends. Admittedly, the 2024 study was done on a much smaller scale, but the contrast is striking.

The question is: has the proportion of Surzhyk speakers really increased significantly – or simply the willingness to admit using it? Could it be that shame is giving way to recognition of Surzhyk as an acceptable tool for communication?

For decades, Surzhyk was a source of embarrassment. Nitsoy was voicing widespread Ukrainian nationalist views when she described it in 2021 as “a rape of the Ukrainian language by Russian”. Pavlo Hrytsenko, director of the Institute of the Ukrainian Language, argued that speaking Surzhyk signalled personal “underdevelopment”, a refusal to master the country’s literary language. Others were even more blunt, suggesting that: “By speaking Surzhyk, we humiliate ourselves.”

The assumption was that Surzhyk speakers leaned lazily toward Russian rather than making the effort to learn proper Ukrainian. These attitudes produced active campaigns to “correct” it, like the 2020 chatbot StopSurzhyk, which suggested literary alternatives for “improper” words.

This stigma was reinforced by the proportion of Ukrainian-Russian words and phrases that make up Surzhyk. Throughout the 20th century, Surzhyk was heavily Russianised, reflecting the dominance of Russian in public life. But more recently, and especially in the wake of Russia’s full-scale invasion of Ukraine in 2022, the balance has shifted. Surzhyk now carries more Ukrainian elements and has been increasingly viewed not as a regression, but a reversal.

A bridge for Russian speakers to Ukrainian

Today, Surzhyk is generally seen by Ukrainian scholars, writers and the wider public as transitional, even useful, and is often used by Russian speakers switching to Ukrainian.

Ukrainian linguistics experts argue that mocking or judging those speaking Surzhyk is misguided, because every language learner passes through such a stage, and that any Surzhyk is better than Russian.

Philologist Svitlana Kovtiukh likens the language to “slippers at home” – meaning that one might wear formal shoes in public but slip into something more comfortable in private. Ukrainians should be encouraged, according to Kovtiukh, to speak literary Ukrainian in official settings – as required by the Language Law – but be free to use Surzhyk in their personal life. What Soviet authorities once dismissed as “weeds” in the national language may actually be the streams that nourish it.

This reversal of perspective reflects a new hierarchy. Once a way for Ukrainian speakers to survive in a Russian-dominated world, Surzhyk is now a way back to Ukrainian for Russian speakers to Ukraine’s national language.

Once abominated by Ukrainians, it is increasingly seen as a tool of linguistic decolonisation. It’s both a practical way for Russian speakers to understand and be understood in Ukraine, and an alternative to what most Ukrainians see as the language of their oppressors.

Making AI quicker, smarter and better is proving to be a very expensive business. Companies like OpenAI are investing billions of dollars in hardware, and the likes of Meta are offering top (human) talent huge salaries for their expertise.

So perhaps it’s no surprise that these businesses have started exploring new ways of making money as well as spending it.

OpenAI, for example, is exploring a partnership with Shopify, one of the world’s largest e-commerce platforms, which helps businesses manage online selling.

The reported deal between the two companies would see OpenAI receive a cut of any Shopify sales that result from recommendations provided by ChatGPT, creating a new revenue stream for OpenAI and more online traffic for Shopify.

But this relationship could be risky for consumers if OpenAI became incentivised to push people towards products, rather than offering genuinely objective recommendations. It might even push recommendations when users of ChatGPT are not looking to buy anything at all.

This situation reminds me of the early days of online advertising when Google was under pressure from shareholders to increase revenues, following the dot-com bubble. Google was (and still is) the world’s leading search engine, in part because it had the best algorithm. But the obvious path to generating revenue – advertising – posed a big dilemma.

Loading search results with adverts would put off users and weaken Google’s position. The company’s solution was to develop targeted advertising, matching ads to search queries to maintain relevance and quality.

Similarly, OpenAI will surely not just flood ChatGPT with links to products. If it did, the quality of its own product would decline, and users would quickly go elsewhere.

So, like Google, it needs to find a subtle way to influence people to shop.

Luckily for OpenAI, the sociable, text-based interface of a chatbot creates ample opportunities to use persuasive techniques to try to influence people’s behaviour.

Processing power of persuasion

One way of thinking about online persuasion is in terms of “metacognition”, the ability to think about thinking, which is very important in the world of sales.

Research suggests that when a customer has high metacognition skills, they are more likely to be sceptical of a salesperson’s tactics, and harder to persuade. When a salesperson has high metacognition, they are good at getting into a customer’s head and making a sale.

One theory of metacognition argues that high levels are influenced by how much sellers and customers know about a product, how much they know about persuasion, and how much they know about each other.

In all three cases, AI may have an advantage.

On any given topic, ChatGPT will “know” more about it than an average person. A particularly knowledgeable person might not get caught out. But nobody is an expert on everything, while ChatGPT can at least pretend to be (like any good salesperson).

AI large language models (known as LLMs) are also up to speed on the latest research on rhetoric, marketing and psychology. They can even identify deceptive sales techniques.

AI can also be tweaked to be persuasive. For instance, research has found that people are more likely to buy something when a salesperson or advert mirrors their personality. One study found that ChatGPT can accurately predict a person’s personality from relatively little information. Over time then, ChatGPT could be programmed to make predictions about us, and then start acting like us.

When it comes to knowledge about each other, most people probably know little about how AI language tools actually work. And if people are also unaware of the incentive AI companies may soon have to recommend products, these recommendations may be met with less scepticism, because an AI chatbot would seemingly have no motive to manipulate.

Meanwhile, like Google, companies such as OpenAI are gathering huge amounts of data about the people who use their software. Initially, this was to train future AI models. But these same data could be used to learn more about people, what makes them tick, and what makes them click “buy”.

Product recommendations from ChatGPT, Google or any other company are not inherently sinister. If data is used to suggest products people genuinely love, this can be helpful.

But being helpful is not the primary motivation here. Just as Google introduced ads because of financial pressure, deals like those between OpenAI and Shopify are a response to the economic pressures the AI industry is facing.

It is great if these systems recommend products a person wants to buy. But what might matter most to AI, regardless of the product, is that they buy it.

Thanks to the runaway global popularity of Netflix’s new animated film, KPop Demon Hunters, cinemas around the world have picked it up and are now screening a sing-along edition.

Huntr/x, the musical girl group featured in the story, has topped charts worldwide with their track Golden.

As the film smashes records and captures audiences everywhere, one question lingers: what makes this animation stand out from the rest? An answer lies in how relatable the main characters are.

The film follows three K-pop girl group members who use their music and voices to protect the world from demonic forces. While the storyline centres on the fantastical notion of “demon hunters”, grounding the protagonists in the guise of K-pop idols adds on-trend authenticity. As co-director Chris Appelhans explained, the aim was “making girls act like real girls, and not just pristine superheroes”.

Rather than dwelling solely on their heroics, the film portrays the characters’ everyday moments and ordinary behaviour. Food, clothes and familiar locations in South Korea are rendered with surprising precision, to the extent that even Korean audiences are astonished at their accuracy, despite the production being based overseas.

But how closely does the film’s version of K-pop reflect the real thing?

Take the first appearance of Huntr/x members Rumi, Mira and Zoey: with only minutes to go before a performance, they are shown devouring kimbap, ramen, fish cakes and snacks – fuel for the stage. In reality, idols may often end up grabbing a quick bite of kimbap or ramen in the car between packed schedules. More commonly, however, strict diets are the norm. There are reports that sometimes trainees – aspiring K-pop idols who are part of an entertainment company’s training programme – are even forced to shed weight by agencies: one of the industry’s darker aspects.

Yet, as idols mature, many develop their own healthier routines, not simply for looks but to ensure longevity in their careers.

Meanwhile, in the case of boy group Saja Boys, the film highlights the fans’ fascination with their sculpted abs. In reality, male idols often put themselves through intense workouts to build impressive physiques, showing off toned bodies and six-packs on stage for their fans.

Then there is the question of accommodation. In the film, Huntr/x members share a luxurious penthouse overlooking Seoul’s skyline. In reality, agencies often provide dorm accommodation to facilitate scheduling and teamwork, usually near the company, and often managers live with artists. The quality varies greatly, with newcomers typically placed in modest housing.

After debut, successful idols may upgrade their accommodation as the money starts to roll in, but a penthouse, as shown in the film, is more fantasy than fact. BTS being a notable exception, progressing from sharing a converted office (not even a proper house) to one of Seoul’s most prestigious apartments. Most idols tend to strike out on their own some years after debut, balancing solo activities with personal life. By then, their choice of home usually reflects their individual earnings.

The film mirrors K-pop reality in other respects. One Huntr/x member, Zoey, is Korean-American – reflecting the industry’s trend since the 2000s towards multinational line-ups designed to create a global audience. Blackpink, for instance, includes two Korean members with overseas backgrounds and one foreign national, which has bolstered their international reach.

The right music

The film also shows Zoey writing and composing songs: many idols are now singer-songwriters. With the industry demanding constant renewal, the shelf life of an “idol” is very short. Writing and producing music has become both a way to extend careers and secure additional income streams. BTS are all credited songwriters, while figures such as BigBang’s G-Dragon, Block B’s Zico, and i-dle’s Soyeon have all built reputations – and royalties – through their creative work.

Increasingly, even K-pop trainees now learn songwriting and production before their debut. Beyond these points, the film captures a wide slice of K-pop culture as it really exists – from fan sign events to the sea of light sticks waving at concerts.

More than any other element, it’s the music that gives the film its sharpest sense of realism.

Executive music producer Ian Eisendrath teamed up with record label THEBLACKLABEL to produce K-pop tracks that sound right at home in the current charts. Blending trendy and catchy hooks with the story itself has drawn in not only animation fans but also audiences lured by the music alone.

Co-director Maggie Kang put it plainly in an interview: “We really wanted to immerse the world in K-pop.” At the same time, she noted that the film deliberately heightens certain aspects of the genre. That kind of exaggeration is only natural in animation, where drama is part of the appeal. What matters is that every flourish is still grounded in reality.

For viewers familiar with Korean culture and K-pop, that means spotting a wealth of details that might otherwise go unnoticed – and it’s this layer of discovery that may well be among the key factors driving the popularity of KPop Demon Hunters.

The collapse of a major system of ocean currents, the meltdown of major ice sheets or the dieback of the Amazon rainforest are all examples of negative climate tipping points. These are the big risks associated with a changing climate, where harmful change becomes self-propelling. Each could cause environmental disasters affecting hundreds of millions of people.

The prospect of such irreversible and massively damaging outcomes is looming ever closer, as we are set to exceed 1.5°C global warming. Every year and every 0.1°C above this threshold increases the risk of crossing negative climate tipping points. To avert them, climate action must accelerate spectacularly. We need to decarbonise the global economy five times faster than the current rate to have reasonable odds of limiting warming well below 2°C.

This sounds both frightening and daunting. We are facing existential risks and to avoid them requires extraordinary rates and scales of social and technological change. It is understandable to feel climate despair or doomism – particularly with the current spate of backsliding on climate commitments.

But there are credible grounds for conditional optimism. They lie in the evidence of positive tipping points – where changes to zero-emission behaviour and technologies become self-propelling. This is now the only plausible way we can accelerate out of trouble, because we have left it way too late for incremental change to rescue us.

Tipping points happen when amplifying feedback within a system gets strong enough to support self-propelling change. Like putting the proverbial microphone too close to the speaker. They can happen in a range of systems, and history shows us they have happened repeatedly in social systems. Think of political revolutions, abrupt shifts in social norms – like the abandonment of smoking in public, or the rapid transition from horse-drawn carriages to cars.

Happily, almost everything that contributes to human-induced greenhouse gas emissions could be positively tipped towards zero emissions. It can take a lot of work to bring a system to a tipping point, but some key sectors have already positively tipped, at least in some countries.

Climate ‘tipping points’ can be positive too – our report sets out how to engineer a domino effect of rapid changes

Norway has tipped from buying petrol and diesel cars to EVs in the space of a decade. The UK abruptly shut down coal burning. While gas temporarily replaced some of coal’s role in electricity generation, rapidly growing renewable power has now replaced coal burning and is starting to displace gas. Neither transition happened by chance. Tipping our societies to zero emissions requires deliberate, intentional action from us all.

In Norway, change was started by social activists in the late 1980s, including members of the pop band A-ha, pushing the government to adopt a package of policies to incentivise EVs. In the UK, tipping was triggered by a rising floor price on carbon in the power sector, a policy that can be traced to the Climate Change Act, which started life as a private member’s bill, in turn born out of decades of environmental activism.

The beauty of tipping points

In my new book, Positive tipping points: How to fix the climate crisis, I highlight how just a small change can make a big difference. A minority can ultimately tip the majority. That minority activates amplifying feedback loops that get stronger with the more people who join in the change. This means we can all play a part in triggering positive tipping points.

We all make decisions about what we consume. Just by adopting a lower emission technology or behaviour (like eating less meat) we encourage others to join us. This is because people imitate one another, and the more people who adopt something the more people they can influence to adopt it too – a phenomenon known as “social contagion”.

With technologies, there are extra amplifiers of “increasing returns”: the more of us who adopt a new technology, the better it will get (through learning by doing), the cheaper it will get (due to economies of scale), and the more other technologies will emerge that make it more useful. This is how solar PV panels, wind turbines and batteries that power EVs have got ever cheaper, better and more accessible.

Policy usually also plays a crucial role in stimulating positive tipping points. Mandates to phase in clean technologies and phase out fossil fuelled ones are particularly effective. But despite polling evidence that roughly 80% of people worldwide support more decisive action on the climate crisis, governments can dither or be captured by vested interests. Sometimes they need to see what we support.

This may inspire us to get involved with social activism, which has its own tipping points. Each person joining a protest movement makes it incrementally easier for the next person to join. This can reach a critical mass – as it did for Fridays for Future and Extinction Rebellion in 2019. Or if, like me, you are not so comfortable on the march, there are other forms of social activism, like divesting from fossil fuels, or bringing civil cases against companies causing the climate crisis and governments failing to adequately respond to it.

Together a fraction of us can trigger positive tipping points to avoid otherwise devastating negative climate tipping points.
