Exmoor fingerpost displayed in London's Natural History Museum
An old wooden signpost from a national park is on display in the Natural History Museum, due to having 12 species of lichen living on it. The fingerpost from Exmoor has been part of the 'Fixing Our Broken Planet' exhibition at the museum since April to act as an example of an item recovered from an area with clean air.Organisers said the aim was to help educate people and "explore nature-based solutions that can help create a more sustainable world".Ranger Charlotte Wray, who assisted in the recovery of the post, said it was "such a joy to help tell the story of Exmoor".
'Lack of pollution'
There are currently over 3,000 wooden fingerposts on Exmoor.The post was originally installed near Trentishoe Common in April 2010, before being collected and transported to the London exhibition.Ms Wray said: "Some of the lichens growing on this fingerpost indicate the high air quality on Exmoor, which is made possible through the lack of pollution and the presence of these highly functioning woodland ecosystems. "It's such a joy to help tell the story of Exmoor and we look forward to visiting the museum to see how the skilled conservators have gone about preserving these unique specimens."The Natural History Museum has been working with the National Park for some time to select the best exhibit.

Why is the UK experiencing a heatwave and what can people do in response?
Temperatures are set to climb to as high as 35C in the latest heatwave to hit parts of the UK. So what is causing it and what are the impacts? – What is causing the heatwave? The UK is on the edge of a 'heat dome' currently sitting over continental Europe which has pushed temperatures to extreme highs in places such as Spain, Italy and Greece. Dr Akshay Deoras, from the University of Reading, says the heat dome, an area of high pressure currently centred on Denmark, with the UK on its western edge, is 'bringing stable, mostly cloudless weather and drawing in hot, dry air from the south'. Dr Michael Byrne, reader in climate science at the University of St Andrews, said heat domes, which occur when high pressure weather systems that normally last a few days get stuck in place for a week or more, are 'nothing new'. But they and other scientists are clear that climate change – caused by human activity such as burning fossil fuels – is making heatwaves more frequent and intense. – So what is the role of climate change in heatwaves? Put simply, the Earth has warmed significantly since pre-industrial times due to humans putting more greenhouse gases into the atmosphere which trap more heat. When hot conditions occur on top of that background warming, for example during a heat dome situation, they are hotter than they would be without it, while it also means heatwaves occur more frequently. So while Dr Byrne says there is nothing new about heat domes, 'what is new are the temperatures heat domes deliver: Europe is more than 2C warmer than in pre-industrial times, so when a heat dome occurs it drives a hotter heatwave', he says. Dr Ben Clarke, research associate in extreme weather and climate change at the Centre for Environmental Policy at Imperial College London, says that without climate change, the UK would still experience periods of fine, warm weather in June – but the hotter atmosphere means that 'fine' weather is now very hot. 'In short, climate change is making 'nice' weather more dangerous, and already dangerous weather more deadly,' he warned. – How do we know climate change is making heatwaves hotter and more frequent? Scientists have conducted numerous 'attribution' studies to assess the role of climate change in extreme weather such as heatwaves, comparing the current conditions with what would have happened in a world without global warming. For example in the summer of 2022, when temperatures smashed through the 40C mark for the first time on record in the UK, scientists found it would have been 'almost impossible' without global warming. Most recently, the same World Weather Attribution group of scientists found the heatwave earlier this month was made about 100 times more likely, or around 2-4C hotter due to global warming. And Met Office analysis has found the kind of 40C temperatures seen in 2022 have a 50:50 chance of happening again in the next 12 years as the risk of extreme heat rises with climate change – with temperatures of 45C now possible in the UK. – What are the impacts of heatwaves? Scientists such as Dr Fredi Otto, from the Centre for Environmental Policy at Imperial and one of the scientists leading the World Weather Attribution work, label heatwaves as 'silent killers'. 'Every year thousands of people in Europe die due to extreme heat, particularly those that live in poorly insulated homes, on busy, polluted roads, and that have already health problems,' she said. Particularly at risk are those who are older, or have pre-existing health conditions: more than 1,000 excess deaths among older people were recorded around the four-day peak of the July 2022 heatwave, with more than 3,000 heat-related deaths in England over that summer. Heatwaves also lead to increased calls to ambulance and emergency services, affect the functioning of hospitals, care homes and schools, hit outdoor workers and damage agriculture, cause transport disruption, raise the risk of wildfires and put water supplies under pressure. Experts also warn extreme heat is linked to worsening symptoms of depression, anxiety and stress, and to increased violence. – So what can people do to protect themselves? Experts suggest a number of practical steps people can take to protect themselves and others against this week's extreme heat. These include trying to keep homes cool by closing windows and curtains during the day to keep out the heat, and opening them at night when it is cooler, drinking plenty of non-alcoholic cold drinks, staying out of the sun, avoiding exercise and checking on elderly people. Measures are also needed to protect communities, including green spaces, better quality housing, temporary cooling centres, and even rescheduling large-scale outdoor events outside the summer months, according to Dr Malcolm Mistry, from the London School of Hygiene and Tropical Medicine. Ultimately though, the risk of extreme heat is only going to worsen with continued climate change, with scientists warning the only way to curb global warming is to cut greenhouse gas emissions to net zero worldwide. As Professor James Dyke, assistant director of the Global Systems Institute at the University of Exeter, puts it: 'These latest European heatwaves are the result of record-breaking greenhouse gas emissions. 'Europe is the fastest-warming continent as a result of human-caused climate change. 'The only way to avoid even more extreme heat is to rapidly phase out fossil fuels.'

Brain rot isn't new – but now we're all talking about it
With excellent timing, your article (From Chimpanzini Bananini to Ballerina Cappuccina: how gen alpha went wild for Italian brain rot animals, 25 June) appeared on the day that 'brain rot' was added to the Oxford English Dictionary. When researching the entry, we discovered that brain rot is nothing new. The earliest evidence of its usage that we found was in Henry David Thoreau's book Walden (1854); in it he lamented society's tendency to devalue complex ideas in favour of simple ones, viewing it as indicative of a general decline in mental and intellectual effort. The term has been applied variously to reading too many books, watching too much television, and listening to 'pimpley music', bringing us up to date with the digital content that takes the blame currently. While it took the last year or so to really cement it in the language, it seems that nothing much has changed except the medium. Concerned parents, citizens, or even linguists can take comfort in one fact revealed by our research: the supposed consumers or victims of brain rot are often the very people using the term (to mean both the content itself and its impact on them). This suggests that – whatever the cost to intelligence or attention spans – they at least retain self-awareness or a sense of irony. To quote David Bowie, 'They're quite aware of what they're going through.'Fiona McPhersonExecutive editor, Oxford English Dictionary Have an opinion on anything you've read in the Guardian today?

Scientists warn of 'catastrophic' risks as labs 'play God' with human DNA
Scientists have taken a bold and controversial step toward creating synthetic human DNA from scratch, a move some critics liken to 'playing God.' The research aims to unlock new treatments for autoimmune disorders, heart failure, viral infections, and age-related diseases. To do so, scientists are developing tools to build large, complex sections of human DNA in the lab and insert them into skin cells to observe how they function. The ultimate goal is to construct entire human chromosomes, a foundational step toward assembling a fully synthetic human genome. But the project has sparked ethical and safety concerns. Experts warn that the technology could have catastrophic risks, leading to biological weapons or genetically engineered 'designer babies.' 'The genie is out of the bottle,' said Professor Bill Earnshaw of the University of Edinburgh. 'If an organization with the right equipment decided to start synthesizing anything, I don't think we could stop them.' Dr Pat Thomas, a longtime campaigner on genetic ethics, added: 'While many scientists have good intentions, the science can be repurposed to harm, and even for warfare.' Every cell in the human body, except red blood cells, contains DNA, the molecule that carries the genetic instructions for life. DNA is composed of just four chemical bases, known as A, G, C, and T. These letters repeat in countless combinations to form the code that shapes everything from eye color to disease risk. Over the next five years, teams from the University of Oxford, Cambridge, Kent, Manchester, and Imperial College London will collaborate to build and test synthetic DNA in the lab. Their short-term goal is to better understand how DNA influences human development, health, and aging. By constructing DNA from scratch, rather than editing existing strands, scientists gain unprecedented control to explore genetic function and test new biological theories. This research could help uncover how faulty cells trigger disease or lead to the creation of disease-resistant tissues and repair techniques for organs like the heart or liver. 'This is about developing therapies that will improve people's lives as they age, leading to healthier aging with less disease,' Dr Julian Sale of Cambridge's MRC Laboratory of Molecular Biology, told the BBC. Dr Sale added that the technology also allows researchers to explore the so-called 'dark matter' of the genome, the vast, little-understood regions of DNA that don't code for proteins but may play critical roles in cellular function. Professor Matthew Hurles of the Wellcome Sanger Institute said the work could revolutionize treatment by revealing why certain cells cause disease and how to fix them. While medical applications may still be years away, researchers say the work could eventually lead to breakthroughs like virus-resistant tissues, lab-grown organs, or advanced cell-based therapies. 'Building DNA from scratch allows us to test out how DNA really works and test out new theories, because currently we can only do that by tweaking DNA in existing living systems.' This approach may also lead to advances beyond the human genome. Philosophy professor Iain Brassington from the University of Manchester highlighted the potential for creating synthetic mitochondria, the cell's energy powerhouses, which could help women with inherited mitochondrial disorders have children without relying on egg donors. But Brassington also warns of serious consequences if the technology is misused. Lab-engineered bacteria designed to clean up oil spills or digest plastic, for example, could wreak havoc if released into the environment.
