‘Zombie spiders' and Darwin collection among fungi archived in Kew digitisation
Kew's Fungarium, an archive beneath the west London garden, is one of the world's biggest and most important collections of fungal diversity, containing more than 1.1 million specimens collected over the past 175 years.
Teams have been creating high resolution images, transcribing the data and uploading it onto Kew's data portal, which grants researchers worldwide remote access to the collection.
The specimens are georeferenced and span decades, meaning experts can observe how a species' range has changed over time, helping to inform conservation plans.
Kew scientists have also been tapping into the genetic information stored in the Fungarium's 50,000 type specimens.
The project, which is a partnership with the National History Museum and is backed by Government funding, aims to sequence about 7,000 of these fungi, making the data publicly available online in the coming years.
This means anyone will be able to see the genetic code of a species, which could help to unlock new compounds and genetic sequences, accelerate the discovery of new chemicals and medicines, and tackle the climate and biodiversity crises.
Dr Ester Gaya, senior research leader in comparative fungal biology, said: 'It is incredibly exciting to imagine what diversity of compounds is hidden away in these collections.
'By sequencing these specimens, we hope to tap into these potential benefits, while providing new tools to accelerate species identification and insights into how fungi relate to one another through time.'
Scientists estimate there are 2.5 million fungal species in the world but only 166,000 have been described.
Shaheenara Chowdhury, operations manager of the Fungarium digitisation, said: 'Fungi have been overlooked by the scientific community for so long, and yet they are amongst the most wonderful and mysterious organisms on the planet.
'It's incredibly exciting to imagine what new discoveries are going to be made with the aid of this new, powerful resource.'
Among the species digitised by the Kew team is Gibellula attenboroughii – or David Attenborough's 'zombie fungus' – named after first being spotted on an episode of BBC's Winterwatch in 2021, having infected an orb-weaving cave spider.
The parasitic fungus species belongs to a group that infects their invertebrate hosts and takes control before killing them as part of their spore-spreading mechanisms.
Other species include Stereum hirsutum, a fungus collected at around 15,000ft during an Everest expedition in 1953, possibly during the climb of Sir Edmund Hillary and Tenzing Norgay.
Another was Cyttaria dawinii, a small globular parasitic fungus collected by Charles Darwin in the Tierra del Fuego archipelago in South America during the HMS Beagle voyage between 1831 and 1836.
Kew scientists also highlighted Hemileia vastatrix, which causes a fungal disease known as coffee rust which is devastating to the coffee genus Coffea and is threatening farms around the world already under pressure from climate change.
The mouldy fungi Penicillium rubens, which Scottish physician Alexander Fleming discovered produced the groundbreaking antibiotic compound in the 1920s, is also included in the digitised archive.

‘Vast Majority' of new homes will have solar panels, says Miliband
Builders could be required to install solar panels on the 'vast majority' of new homes in England, according to Energy Secretary Ed Miliband. It comes a month after Downing Street confirmed the panels should be installed on as many new properties as possible amid speculation that ministers will make them a mandatory requirement on new builds by 2027. Speaking to the BBC, Mr Miliband described the proposed policy as 'just common sense' and said the panels should be 'almost universal' on English homes. Changes to regulations will be laid out in the Future Homes Standard, due to be published later this year. The previous Conservative Government considered a proposal that would have mandated rooftop solar panels to cover 40% of a building's ground area or equivalent. 'The problem about the previous system was that it said you would had to have a certain percentage of coverage of solar panels, but if you couldn't achieve that percentage, you didn't have to do anything at all,' Mr Miliband said. 'Under our plans, we are not going to say that. We are going to say even if you can't hit 40% you will still have to have some solar panels, except in rare, exceptional cases.' He added that the number of homes fitted with solar panels needed to be 'much higher'. The policy is estimated to add between £3,000 and £4,000 to the cost of construction, but to then save owners more than £1,000 on their annual energy bills, according to the Times, which first reported the change. Asked in May whether housebuilders would be legally required to fit the panels, Prime Minister Sir Keir Starmer's official spokesman said: 'Of course we want to see solar panels on as many new homes as possible. 'The Future Homes Standard, which will be published in the coming months, will include measures to drive this, we're working on the detail of that and will provide an update on that in due course. 'But it's good news for householders who want lower energy bills.' Under the Government's new proposals, 80% of new builds would reportedly be required to have solar panels covering 40% of their ground area, while 19% would have slightly fewer because of exemptions, including roof pitch and overshading. Ministers last year rejected a private members' Bill aiming to force housebuilders to install solar panels on the roof of every new home, saying the proposals would potentially slow down construction and add to building manifesto included a pledge to build 1.5 million new homes over the course of the Parliament.

Politicians seem reluctant to take necessary action over sea level rise
There seems to be an inability among politicians to take in what scientists are telling us about the consequences of the climate crisis. Perhaps the most glaring example relates to the Guardian's latest report on sea level rise, which said that whatever we do now, the rise will have devastating consequences for coastal communities, causing millions of people to migrate to higher ground. Greenland and the west Antarctic ice caps are doomed to melt. Even in countries that do take cutting carbon emissions seriously, such as the UK, governments do not seem to have accepted that the prediction about sea level rise means policies must adapt to damage that has already been done. The coastline of the North Sea is a classic example. Stretches of England's east coast both in and south of Yorkshire are eroding, and large areas are close to or at sea level already. A storm surge coinciding with a high tide, like the one that killed hundreds in 1953, may be a rarity, but each year a similar event becomes more likely to overwhelm the existing sea defences. And yet the government is still talking about building nuclear power stations with a 150-year lifespan on this coast, notably Sizewell C, and small modular reactors on other sites. Future generations may wonder why scientists' warnings were so easily ignored.

Dehorning rhinos reduces poaching by 80%, study finds
Cutting the horns off rhinos causes a large reduction in poaching, according to a new study, which raises questions about the effectiveness of expensive anti-poaching techniques used to protect the African mammals. Poaching for horn is a significant threat to the world's five rhino species. The substance, which is similar to human fingernails, is commonly used for traditional medicine in China, Vietnam and other Asian countries. Dealers in the hidden market will pay tens of thousands of dollars for the horns, which are falsely believed to be effective at treating fevers, pain and a low sex drive in traditional medicine. But new research in the journal Science has highlighted ways to better protect the animals from illegal hunters. An assessment of rhino protection methods in the Greater Kruger region of South Africa – home to a quarter of the continent's rhinos – found that removing horns reduced poaching by nearly 80% between 2017 and 2023. In a collaboration between scientists, conservationists and government officials, the research found no statistical evidence that traditional anti-poaching interventions – such as rangers, detection cameras, dog tracking and helicopters – caused significant reductions in rhino poaching, despite their multimillion-dollar cost, even though they were successful at detecting hundreds of poachers. 'Dehorning rhinos to reduce incentives for poaching was found to achieve a 78% reduction in poaching using just 1.2% of the overall rhino protection budget,' said Dr Tim Kuiper of Nelson Mandela University, a lead author of the study. 'We might need to rethink our goals. Do we just want to arrest poachers? It doesn't appear to be making a massive difference to reducing rhino poaching.' To dehorn a rhino, workers sedate the animal, apply a blindfold and earplugs, and cut off the horn with a power saw. The horn will gradually regrow – an average rhino needs to be dehorned every 1.5 to two years. The process poses a very low risk to the animal and does not hurt it. 'The headline result is that dehorning stood out for its effectiveness. We are cautious to say that the other interventions are not working. They worked when measured by whether they were detecting poachers. But detecting and arresting a load of poachers doesn't necessarily bend the curve on rhino poaching,' Kuiper said. In South Africa, rhino poaching remains high, with 103 killed in the first three months of 2025. Last year, 420 were lost. In recent decades, rhino populations have collapsed in Asia and Africa due to poaching and habitat loss, continuing falls driven by European colonial hunters. But the researchers behind the project, representing the University of Cape Town, Nelson Mandela University, University of Stellenbosch and the University of Oxford and other conservation institutions, cautioned that dehorning rhinos was not a magic bullet. A significant stump of horn mass remains on the rhino after dehorning, and some poachers were still prepared to kill rhinos for this section. Sharon Haussmann, a pioneer in rhino conservation in South Africa and co-author on the paper, played a leading role in coordinating conservation efforts in the study area. She died unexpectedly at the weekend and Kuiper wanted to highlight the collaboration between different sectors that are often mistrustful of each other in her memory. 'Is a rhino still a rhino without its horn? That's a bigger question,' said Kuiper. One study of black rhinos indicated that while poaching rates decreased, dehorned animals became more timid and covered much smaller ranges. Researchers believe that horn is used to establish territories and dehorned rhinos were unable to do this after the procedure. 'We wouldn't like to keep dehorning them for the next 100 years,' Kuiper said. 'Ideally we would like to address the drivers of poaching. But it is better than the impacts of poaching' Find more age of extinction coverage here, and follow the biodiversity reporters Phoebe Weston and Patrick Greenfield in the Guardian app for more nature coverage
