The Guardian view on the public's dinomania: passion for palaeontology endures through the ages
This spring, the BBC revived its 1999 hit series Walking With Dinosaurs. Not a week goes by without headlines announcing the discovery of a new species or new theories on how they behaved. Publishers produce an endless stream of dino-related fact and fiction, particularly for children. Palaeontology – at least when focused on the dinosaurs of the Mesozoic, or our hominin forebears – has long exerted an extraordinary hold on the public imagination.
Yet it's a marginal field in terms of academic prestige and scientific funding, as Dr Chris Manias, a historian of science, points out in the essay collection Palaeontology in Public, published last year. (Dinosaurs are themselves a small part of the discipline; the vast mass of fossils are invertebrates, micro-organisms or plants. Good luck getting a movie made about stromatolites).
The spectacular scale and fearsome nature of creatures such as Spinosaurus, the magic of conjuring extraordinary life from a handful of rocks tens of millions years old, and the mirroring of myths about dragons and other ancient beasts may all play a part in its appeal. Entertainment has always helped: the Crystal Palace dinosaurs were created in the 1850s to encourage interest in recent discoveries (Richard Owen, who coined the term dinosaur, provided advice.) Arthur Conan Doyle's 1912 novel The Lost World portrayed a South American plateau where prehistoric creatures still roamed. Some of today's palaeontologists were drawn to the field by watching the first Jurassic Park movie as children.
But the science itself has been central too. In the 19th century, the US palaeontologists Othniel Charles Marsh and Edward Drinker Cope vied to outshine each other in the bitter 'Bone Wars', with academic rigour and ethics taking second place to headline-grabbing glory. In the 'dinosaur renaissance' of the 1960s, experts showed the creatures to be more sophisticated, active and interesting than previously imagined. The feathered dinosaurs found in Liaoning, China, in the 1990s have revolutionised our understanding – even if the Jurassic franchise makers, and many dinosaur fans, still draw the line at a downy Tyrannosaurus rex. In recent years, experts have identified a new dinosaur every week or so. New technology is unlocking details of their appearance and behaviour.
The original Jurassic Park was a tourist resort inhabited by dinosaurs brought back from extinction. In the latest film, the plot is driven by big pharma's hunt for prehistoric DNA that could drive a medical breakthrough. That parallels the tension Dr Manias notes around palaeontology itself: is it primarily a 'luxury', which entertains more than it enlightens, or 'useful'? Jaw-dropping giants like Patagotitan still captivate adults and, especially, children. But there are lessons here too. In the past, the field appeared to offer a narrative of progress, as lumbering creatures gave way to mammals and ultimately – tada! – the triumph of humans. Now it is an instructive tale of uncertainty, offering powerful insights into time, nature and how life has fared at times of huge and rapid changes in climactic conditions.

What's behind the global surge of new Covid variant XFG – and should you get vaccinated?
A new Covid variant, XFG, is spreading across the world, with Southeast Asia countries reporting a surge in cases. In the UK, the Health Security Agency has said the variant accounted for 30 per cent of cases in England in late June. However, the true extent of the variant's spread remains uncertain, largely due to a significant reduction in Covid-19 testing compared to the peak of the global pandemic five years ago. What do we know about the variant XFG? XFG is a mix of earlier variants LF.7 and LP.8.1.2, with the earliest sample collected on 27 January 2025, according to the WHO. As of 22 June 2025, there were 1648 XFG sequences detected from 38 countries, representing 22.7 per cent of the global cases that week, up from 7.4 per cent four weeks prior. The variant has been the fastest growing in the last month compared to any other currently circulating types. Recent reports from Southeast Asian countries have shown a simultaneous rise in cases and hospitalisations of this variant. However WHO has designated the risk of this new variant as 'low' and commented that current data do not indicate that this variant leads to more severe illness or deaths than other variants in circulation. Why has there been a surge in new cases? The World Health Organization (WHO) lists Stratus as one of its 'variants under monitoring', which means they may require prioritised attention and tracking by health authorities due to their increased prevalence and potential public health implications. The WHO has said the growth advantage this variant has over others is 'moderate', as XFG is growing substantially across all WHO regions. Data shows from the week of 5 May to the week of 26 May, XFG has increased in proportion across main global regions, including from 10.6 per cent to 16.7 per cent in Europe and from 7.8 per cent to 26.5 per cent in the Americas (AMR). In Southeast Asia, the XFG proportion increased from 17.3 per cent to 68.7 per cent in the Southeast Asia Region (SEAR). 'It is normal for viruses to mutate and change over time,' Dr Alex Allen, consultant epidemiologist of UKHSA said, adding that it continues to monitor all strains of Covid in the UK What are the symptoms? One reported symptom of Stratus is a hoarse throat, according to some experts. 'One of the most noticeable symptoms of the Stratus variant is hoarseness, which includes a scratchy or raspy voice', Dr Kaywaan Khan, Harley Street GP and founder of Hannah London Clinic, told Cosmopolitan UK He said in general, the symptoms of Stratus tend to be 'mild to moderate'. Healthcare experts have stressed, however, that there is no evidence that the new strain is more deadly or serious than previous variants, and that current Covid vaccines are expected to remain effective and protect anyone infected from severe illness. Should you get vaccinated? Under UK guidelines, people aged 75 years and older, residents in care homes for older people, and those aged 6 months and over with a weakened immune system were offered a dose of Covid-19 vaccine this spring. Patients were offered an appointment between April and June, with those at highest risk being called in first. If you are turning 75 years of age between April and June, you do not have to wait until your birthday; you can attend when you are called for vaccination. For the next round of vaccinations, patients will be able to book from 1 September 2025 for vaccines to be given from 1 October, NHS England has advised health providers. The NHS will get in touch to offer you the Covid vaccine if you are eligible.

Experts warn millions diagnosed with ADHD may not have it - they're likely suffering another, common disorder instead
A major new analysis has fueled concerns over the accuracy of tests that diagnose ADHD, suggesting many of those told they have the disorder are in fact suffering depression. Scientists from Scandinavia and Brazil analysed common methods of diagnosing adult ADHD described in nearly 300 medical studies. Many of these diagnostic tests are currently used by doctors in the UK to spot the condition. The findings showed that in nearly half the studies, the scientists failed to rule out other causes of ADHD-like symptoms, such as depression. This means, they concluded, that the diagnostic test used may be unreliable, and therefore providing inaccurate results in the real world. 'You don't actually know if subjects have other mental disorders such as depression or schizophrenia,' the experts wrote in their report. The latest findings come amid a rapid rise in adult ADHD diagnoses in the UK, with cases rising 20-fold over the last two decades. It's a phenomenon that has raised the concern of some of the country's top psychologists and spurred a NHS investigation, launched in March. Experts have warned that rogue private clinics are over-diagnosing the condition and have questioned the widespread prescribing of powerful stimulant drugs to treat it. In the latest analysis, scientists found that a psychiatrist or psychologist made the diagnosis in only 35 per cent of ADHD cases examined. Adults in the UK can only be formally assessed for ADHD on the NHS by a psychiatrist, psychologist or specialist ADHD nurse. In some cases discovered by the researchers, it was explicitly stated that the assessment and diagnosis of ADHD was made by subjects themselves. One patient was reported to have reached their diagnosis with the help of a computer, the researchers explained. 'In psychiatry, we really need that all diagnoses, not just ADHD, are made with the same uniform criteria and by trained professionals,' said co-author of the study, consultant psychiatrist Dr Julie Nordgaard from the University of Copenhagen. 'Otherwise, we cannot rely on the results or compare them across studies. 'Especially in a situation where a diagnosis such as ADHD in adults is increasing, we need to be very thorough and have a solid foundation. 'Otherwise, we risk too many people getting a wrong diagnosis and not being able to give them the most effective treatment. 'Or they risk receiving unnecessary treatment that causes side-effects.' Symptoms of depression can often mimic those of ADHD, research has shown. A neurodevelopmental disorder, ADHD affects concentration, impulse control and activity levels. Common symptoms include restlessness, distractibility, forgetfulness, difficulty following instructions or managing time, and making impulsive decisions. Depression, which affects roughly one in six adults in the UK, can look remarkably similar. Those with the mood disorder often experience poor concentration, low energy and disturbed sleep. Both ADHD and depression can also cause changes in appetite, restlessness and irritability as well as difficulty initiating and completing tasks. Schizophrenia, though less common—affecting just one per cent of the UK population —can also resemble ADHD in some cases. Traditionally characterised by psychotic symptoms like hallucinations and delusions, schizophrenia can also cause attention problems, particularly in its early stages. The researchers concluded it's impossible to know which disorders and symptoms were actually being affected by the treatments investigated in the trials. 'This makes the research results from many of these clinical trials difficult to utilise,' said associate professor at the University of Copenhagen Dr Mads Gram Henrikson. The study comes just months after the latest NHS figures revealed more than 549,000 people in England were waiting for an ADHD assessment at the end of March 2025—up from 416,000 the previous year. Of those currently waiting for an assessment, around 304,000 had been waiting at least a year—and 144,000 for two years or more, as NHS services struggle to keep up with spiraling demand. More than two-thirds (382,000) were aged between five and 24. Last year a MailOnline investigation revealed that doctors were dishing out powerful ADHD drugs at 10-times the rate in some parts of England than others. NHS data shows as many as one in 100 people in some areas are taking ADHD medications, compared to just one in 1,000 in nearby regions. Commenting on the findings, experts warned of over-diagnosis and 'mass-prescribing' could be putting public health at risk. University College London psychiatrist Professor Joanna Moncrieff, a vocal critic of medication overuse, said ADHD diagnosis is 'incredibly subjective'. 'One psychiatrist may think almost everyone has it, while another thinks very few do,' she said. 'We all have ADHD symptoms to some extent.' She added that private clinics are often quicker to diagnose than the NHS, making a diagnosis more likely in the independent sector. Professor Moncrieff said patients were increasingly demanding an ADHD diagnosis as the 'answer' to problems they are experiencing in areas like their work. 'This concept of ADHD has got out there and everyone is reinterpreting their difficulties in the light this new idea, 'I'm not bored and don't like my job, I have ADHD',' she said. 'Stimulants make people feel good, they make them feel confident, they make people feel a little bit euphoric, energetic, so of course people are going to be rating themselves as doing better.' Rising interest in ADHD is thought to be fueled in part by celebrities sharing their diagnoses — including Katie Price, Love Island's Olivia Attwood, Sheridan Smith and former Bake Off host Sue Perkins. Attwood said it caused 'a lot of stress' in her teens, while Price said it explained why she never felt there would be 'consequences' for her actions. Perkins said the diagnosis made 'everything make sense'. Social media has also been blamed, with users praising ADHD meds for calming them and boosting focus. NHS prescriptions have doubled in six years to 230,000, with the sharpest rise—nearly 60 per cent in a year—among women in their late 20s and early 30s. Use among 25 to 39-year-olds has increased five-fold since 2015. In response, NHS England launched a taskforce to assess the scale of the condition. ADHD is also behind a surge in disability benefit claims. One in five now relate to behavioural conditions, with over 52,000 adults—mostly aged 16 to 29—listing ADHD as their main condition.

Can you see circles or rectangles? And does the answer depend on where you grew up?
Do people from different cultures and environments see the world differently? Two recent studies have different takes on this decades-long controversy. The answer might be more complicated, and more interesting, than either study suggests. One study, led by Ivan Kroupin at the London School of Economics, asked how people from different cultures perceived a visual illusion known as the Coffer illusion. They discovered that people in the UK and US saw it mainly in one way, as comprising rectangles – while people from rural communities in Namibia typically saw it another way: as containing circles. To explain these differences, Kroupin and colleagues appeal to a hypothesis raised more than 60 years ago and argued about ever since. The idea is that people in western industrialised countries (these days known by the acronym 'weird' – for western, educated, industrialised, rich and democratic – a summary that is increasingly questionable) see things in a specific way because they are generally exposed to highly 'carpentered' environments, with lots of straight lines, right angles – visual features common in western architecture. By contrast, people from non-'weird' societies – like those in rural Namibia – inhabit environments with fewer sharp lines and angular geometric forms, so their visual abilities will be tuned differently. The study argues that the tendency of rural Namibians to see circles rather than rectangles in the Coffer illusion is due to their environments being dominated by structures such as round huts instead of angular environments. They back up this conclusion with similar results from several other visual illusions, all supposedly tapping into basic brain mechanisms involved in visual perception. So far, so good for the cross-cultural perceptual psychologists, and for the 'carpentered world' hypothesis. The second study, by Dorsa Amir and Chaz Firestone, takes a sledgehammer to this hypothesis, but for the much better-known illusion: the Müller-Lyer illusion. Two lines of equal length seem to be different lengths because of the context provided by inward-pointing, compared with outward-pointing, arrowheads. It's a very powerful illusion. I've seen it on thousands of occasions and it works every time for me. There are many explanations for why the Müller-Lyer illusion is so effective. One of the more popular is that the arrowheads are interpreted by the brain as cues about three-dimensional depth, so our brains implicitly interpret the illusion as representing an object of some kind, with right angles and straight lines. This explanation fits neatly with the 'carpentered world' hypothesis – and indeed a lot of early support for this hypothesis relied on apparent cultural variability in how the Müller-Lyer illusion is perceived. In their study, Amir and Firestone carefully and convincingly dismantle this explanation. They point out that non-human animals experience the illusion, as shown in a range of studies in which animals (including guppies, pigeons and bearded dragons) are trained to prefer the longer of two lines, and then presented with the Müller-Lyer image. They show that it works without straight lines, and for touch as well as vision. They note that it even works for people who until recently have been blind, referencing an astonishing experiment in which nine children, blind from birth because of dense cataracts, were shown the illusion immediately after the cataracts were surgically removed. Not only had these children not seen highly carpentered environments – they hadn't seen anything at all. After you absorb their analysis, it's pretty clear that the Müller-Lyer illusion is not due to culturally specific exposure to carpentry. Why the discrepancy? There are several possibilities. Perhaps there are reasons why cross-cultural variability should be expected for the Coffer but not the Müller-Lyer illusion (one possibility here is that the Coffer illusion is based on how people pay attention to things, rather than on some more basic aspect of perception). It could also be that there are systematic differences in perception between cultures, but that the 'carpentered world' hypothesis is not the correct explanation. It's also worth noting that the Kroupin study has some potential weaknesses. For example, the UK/US and Namibian participants were exposed to the illusions using very different methods. All in all, the jury remains out and – favourite scientist punt coming up – 'more research is needed'. The notion that people from different cultures vary in how they experience things is certainly plausible. There's a wealth of evidence that as we grow up our brains are shaped, at least to some extent, by features of our environments. And just as we all differ in our externally visible characteristics – height, body shape and so on – we will all differ on the inside too. As the author Anaïs Nin put it in quoting the Talmud: 'We do not see things as they are, we see them as we are.' For me, an important implication of this line of thought is that there are likely to be substantial differences in perception within 'groups' as well as between them. This will probably hold however these 'groups' are defined, whether as different cultures or as a contrast between 'neurotypical' and 'neurodivergent' people. I believe that paying more attention to within-group perceptual diversity will help us to better interpret the differences we do find between groups, and equip us with the tools needed to resist relying on simple cultural stereotypes as explanations. More research is needed here too. But it's on the way. In the Perception Census, a project led by my research group at the University of Sussex together with professor Fiona Macpherson at the University of Glasgow, we are studying how perception differs in a large sample of about 40,000 people from more than 100 countries. Our experiment includes not just one or two visual illusions but more than 50 different experiments probing many different aspects of perception. When we're done analysing the data, we hope to deliver a uniquely detailed picture of how people experience their world, both within and between cultures. We'll also make the data openly available for other researchers to explore new ideas in this important area. One critical insight lies behind all these questions. How things seem is not how they are. For each of us, it might seem as though we see the world exactly as it is; as if our senses are transparent windows through with the world pours itself directly into our mind. But how things are is very different. The objective world no doubt exists, but the world we experience is always an active construction, a kind of 'controlled hallucination' in which the brain uses sensory signals to update and calibrate its best interpretation of what's going on. What we experience is this interpretation, not a 'readout' of the sensory information. For me, this is the key insight that underlies any claim about perceptual diversity. When we take it fully on board, it encourages a much-needed humility about our own ways of seeing. We live in perceptual echo chambers, just as we do in those of social media, and the first step to escaping any echo chamber is to realise that you're in one.
