The former coal mine which became a work of art
As relics of our industrial past go, the Crawick Multiverse is a pretty unusual one.
Once an opencast coalmine in Upper Nithsdale in southern Scotland, it is now a landscape artwork created by the late Charles Jencks.
It was officially opened 10 years ago on the longest day of the year, the summer solstice of 21 June 2015.
The hope was that it could attract international visitors and help boost businesses in nearby Sanquhar, Kelloholm and Kirkconnel.
Materials found on the site - including 2,000 large boulders - were used to create the work.
The £1m project - funded by the Duke of Buccleuch on his own land - followed in the footsteps of other works by Mr Jencks including the Garden of Cosmic Speculation, also in Dumfries and Galloway.
The artist - who died in 2019 - said at the time of the opening: "This former opencast coal site, nestled in a bowl of large rolling hills, never did produce enough black gold to keep digging.
"But it did, accidentally, create the bones of a marvellous ecology.
"This work of land art, created primarily from earth and boulders on the site, celebrates the surrounding Scottish countryside and its landmarks, looking outwards and back in time."
The Duke of Buccleuch was delighted with the outcome.
Speaking in 2015, he said the site had become a "brutal eyesore" and an "embarrassment".
So when his "neighbour from down the road" - Mr Jencks - had offered to transform the area, they were "just over the moon".
Reflecting on it today, he said he was still impressed with the final outcome.
"The vision of Charles Jencks, which I supported, extended far beyond its original purpose of removing a derelict opencast mine eyesore to the creation of an internationally-recognised work of land art," he said.
"Charles's ambition to represent in artistic form elements of the vast cosmos in which our planet is but a minute speck, included galaxies, superclusters and the multiverse itself.
"He sought the input of the leading international scientists in the field including Lord Rees, the Astronomer Royal and won their admiration."
He praised the work of the trust which now runs it and wished them all the best for their second decade.
Ten years on, though, what has the impact been?
Ronnie Bradford, community development officer at the nearby Sanquhar Enterprise Company, said it had brought "several benefits" to the area.
"The unique and inspired transformation of the former opencast coal mine has attracted visitors, supporting local businesses, increasing tourism in the area and raising the profile of Upper Nithsdale," he said.
"Local residents have been hired for roles at the site with local trades being engaged in developing the site, ensuring good community involvement in its operations."
He said it also hosted school visits, community group trips and promoted affordable access for nearby residents.
"The open-air venue hosts festivals, performance art and music events, bringing large-scale entertainment and social opportunities to the region often at 'off season' times of the year."
The site now attracts about 10,000 visitors a year and has seen improvements carried out over the past decade to upgrade visitor facilities.
A 55-acre site requires plenty of maintenance with a team of four local young people in "front of house" roles, managed by operations manager Brian Johnson and supported by volunteer trustees.
It was also recently designated as a significantly important designed landscape by Historic Environment Scotland.
A special celebration took place on Saturday to mark the solstice and also reflect on its first 10 years.
Gillian Khosla, who chairs The Crawick Multiverse Trust, is proud of what has been achieved but also has an eye on the future.
"We stand on the shoulders of the artist and skilled workers who created and now develop this unique site, which has repurposed a derelict and depleted coal mine into an important asset for Upper Nithsdale," she said.
"A decade on from opening, now is the time to plan for the next decades to further develop our audiences and increase biodiversity.
"Our aim is to be sustainable, both environmentally and financially."
She said that future could be shaped by others and they were open to ideas of how to develop the site.
In the meantime, they hope visitors will flock to their solstice celebrations and other summer events.
"Please continue to visit and share the magnificence of the Multiverse with your friends," she added.
It certainly appears to have left its past as an industrial eyesore a long way behind.

Scientists engineer bacteria to turn plastic waste into painkillers
Tales of turning water into wine or weaving straw into gold are one thing, but a new study shows that scientists can transform trash into . . . Tylenol? Scientists at the University of Edinburgh were able to convert plastic waste into paracetamol, aka acetaminophen, the active ingredient in the pain reliever Tylenol. Stranger yet, they pulled off the alchemical feat using the bacteria E. coli. 'We're able to transform a prolific environmental and societal waste into such a globally important medication in a way that's completely impossible, using chemistry alone or using biology alone,' says study coauthor Stephen Wallace, a chemical biotechnologist at the University of Edinburgh in Scotland. The research team began with polyethylene terephthalate (PET), a common plastic found in food packaging and polyester clothing. Using established chemical methods, they broke down the PET plastic into a precursor molecule and then added it into a cell culture of E. coli that was genetically modified. Enzymes in the modified E. coli bacteria were able to convert the plastic precursor into paracetamol 92% of the time. The transformation relies on a chemical process known as a Lossen rearrangement, which can convert one kind of molecule into a different kind of molecule. Scientists have known about the Lossen rearrangement for more than 100 years, but generally observe the phenomenon in a flask or a test tube. The research group is now working with pharmaceutical makers including AstraZeneca, one of the study's sponsors, to replicate the same chemical transformations on a larger scale. The new research isn't the first to observe the way that bacteria can be deployed to usefully break down plastic. Researchers have previously studied how wastewater bacteria found in urban waterways use a special enzyme to chew up plastic trash and convert it into carbon-based food. As we grapple with the cascading environmental and health effects that decades of proliferating plastics have wrought on the planet, bacteria capable of converting plastic into harmless or even useful molecules is a promising area of research.

The Next Acetaminophen Tablet You Take Could Be Made From PET
Jun 27, 2025 8:53 AM This research could represent the first documented case of acetaminophen production from plastic waste using E. coli bacteria. acetaminophen pill box, boxpaper, blister tablets Photograph: Jorge Martinez Researchers at the University of Edinburgh have succeeded in transforming certain plastic waste into acetaminophen using the natural properties of the common bacterium Escherichia coli ( E. coli ). This breakthrough represents a milestone with the potential to drive more sustainable methods of drug production and, at the same time, contribute to the reduction of plastic pollution globally. The study, led by Stephen Wallace, revealed that E. coli cells contain phosphate, an organic compound capable of catalyzing a chemical reaction known as Lossen rearrangement. In general terms, this process involves the rearrangement of the atoms of a hydroxamate ester molecule to form a new structure called isocyanate, a chemical intermediate that, when reacted with water, produces primary amines. These substances are essential in numerous biological processes and in drug synthesis. Using synthetic biology, the scientists manipulated the bacteria to redirect their internal chemistry and transform a PET-derived molecule known as terephthalic acid into the active ingredient in acetaminophen. They used a fermentation process, similar to that used in brewing beer, to accelerate the conversion of industrial PET waste into the drug, obtaining results in less than 24 hours. According to the findings, approximately 90 percent of the final product corresponded to acetaminophen. Importantly, this conversion was done at room temperature and with virtually no carbon emissions, suggesting that the drug can be produced in a more environmentally friendly way. Wallace noted that what was most surprising about the process was that the Lossen rearrangement occurred naturally within living bacteria, without the need for laboratory catalysts. That is, they took advantage of the microbial cells' own capabilities to trigger the desired reaction. 'The funny thing is that we didn't have to teach the bacteria how to do the reaction: The trick was to realize that they already had the tools, and we just had to guide them,' explained the researcher in statements reported by El País. 'We used synthetic biology to build new metabolic pathways within the bacteria that guide their chemistry toward producing the compound we wanted. In this case, a drug.' Sustainable Drug Production The work, published in the journal Nature, could be the first documented case of acetaminophen production from plastic waste using E. coli . However, the authors stress that further studies will be necessary to achieve industrial-scale production. In addition, they caution that the safety and efficacy of the resulting drug in humans have yet to be evaluated, so future research will be required. Despite these limitations, the scientists emphasize that their results open up new possibilities for addressing the problem of plastic waste and reducing greenhouse gas emissions associated with drug manufacturing. Currently, the production of drugs such as acetaminophen consumes thousands of tons of fossil fuels, especially petroleum, which contributes significantly to climate change. In turn, PET generates more than 350 million tons of waste per year, causing serious damage to the environment. Although this material is recyclable, current methods often result in products that perpetuate global plastic pollution. 'This work demonstrates that PET plastic is not just a waste product or a material destined to become more plastic: Microorganisms can transform it into valuable new products, including those with therapeutic potential,' concluded Wallace.

60-year mystery of Aussie plant finally cracked by scientists
Australian scientists have gone to great lengths to crack a decades-long mystery of how a native plant that has continued to grow and thrive in a patch of land in Western Australia, with the answer under their noses all along. There are 130 known species of boronia across Australia and New Caledonia, with the majority easily recognisable from their pretty, open-petalled flowers. However, 18 species growing in a triangle between Kalbarri, Augusta and Esperance in WA have all boasted "weird and wonderful" flowers that are closed off to most pollinators. How the plant continues to spread stumped scientists for over 60 years. "The location has a spectacularly diverse ecosystem, and it's a really special place from an ecological viewpoint," Doug Hilton, scientist and CEO of CSIRO, told Yahoo News. "The weird flowers of these boronias have suggested to scientists for over 60 years that there must be pure pollinators of the plants. It couldn't have evolved that way by accident." This 'pure pollinator' — an animal or insect that exclusively pollinates a plant — has been elusive to scientists for decades. But for the last 15 years, Doug and his team have been tirelessly working to prove a theory. Over 60 years, scientists who have encountered the boronia species have made suggestions on who the mystery pollinator could be, and different insects have been hypothesised. "If you look in the scientific papers, there's an occasional reference to a moth, but nothing ever came of it. They had never been collected systematically or photographed," Doug explained. One of the reasons why the moth species called Heliozelidae was never previously pursued was because, unlike many other types of moths, they fly during the day. They are seldom attracted to lights, so they're underrepresented in museum collections. The best way to collect and study them is to sweep a butterfly net over plants and look inside — literally. Images show Doug standing in Western Australia with his head inside a butterfly net. "We found they had the right structure at their abdomen that collects the pollen of the boronias, and these structures are like nothing that has been seen in the other 150,000 species of moths and butterflies; they're absolutely unique," he said. "It was a real Eureka moment." The moths and the boronias have an 'obligate mutualism', meaning they both rely on the other to survive. "It's great for the moth because she can pollinate the plants, and her caterpillars have food, and therefore the species survives as she passes on her genes. And it's good for the plant, because they now have a very efficient pollinator... it's all about balance," he said. Doug continues to study the insects to further deepen the evidence that they are responsible for the plants, and explained a discovery like this is the reason he became a scientist in the first place. " I think that scientists have an obligation to talk to the community about the work they do, and I think there's an appetite for people to understand the wonder of the world," he said. "There's a lot of bad news and a lot of pessimism in the world right now. I think if you can begin to understand how the world works, and do it through science, that's really valuable."
