With lockdown and the long winter nights shuffling the nation’s emotions like a ham-fisted magician with a damp deck of cards, we have no doubt all suffered from a case of the winter blues at some point recently. While the Museum and its inspiring specimens have been closed to visitors we have tried out some new approaches to bring you the solace and creative inspiration that nature can provide.
Drawn to Nature is a new series of online events designed to lift people’s spirits with a combined art and science activity. Originally planned as a wellbeing event to take place in the Museum, the online version was created in response to the last lockdown. We start each session with a short talk by a member of the Museum’s collections or research team, who share their passion for a selection of favourite specimens. The talk is followed by a chance for viewers to explore their creative sides by drawing the specimens, while learning more by about them through some Q&A.
It’s not an art lesson as such, but more a chance for people to find inspiration from some of the jewels of the natural world held in our collections. We hope it helps people to relax, find inspiration, immerse themselves in a creative activity, and learn a little natural history at the same time.

Our first session came from Life Collections manager Mark Carnall, who talked us through the natural history of Nautiloids, the fascinating shelled molluscs that are related to other cephalopods such as squid and octopus. Lit and arranged beautifully by our Events Manager Laura Ashby, their intricate chambered shells and 100 tentacles proved a challenging subject, but one that resulted in an array of wonderful artworks in a variety of styles and media shared on social media.
Following Mark’s talk, we explored some of the wonderful specimens from our entomology collections with our expert speaker Zoe Simmons, Head of Life Collections. Zoe picked out some of the most beautiful flies from our five million-plus insects. Using microscopes, specialist lighting, and careful placement, the specimens were a real hit and again followed by some inspired artworks posted online by attendees from across the world (‘best night of lockdown yet!’ enthused one attendee).

And there’s more to come. Tomorrow evening (Wednesday 10 March), Earth Collections Manager Dr Hilary Ketchum introduces the strange-looking carnivorous marine reptiles of the Jurassic – the plesiosaurs. We hope to bring you yet more of the inspirational well-being the natural world has to offer.

In the summer of 2014 a strange building began to take shape just outside MoMA PS1, a contemporary art centre in New York City. It looked like someone had started building an igloo and then got carried away, so that the ice-white bricks rose into huge towers. It was a captivating sight, but the truly impressive thing about this building was not so much its looks but the fact that it had been grown.
The installation, called Hy-Fi, was designed and created by The Living, an architectural design studio in New York. Each of the 10,000 bricks had been made by packing agricultural waste and mycelium, the fungus that makes mushrooms, into a mould and letting them grow into a solid mass.
This mushroom monument gave architectural researcher Phil Ayres an idea. ‘It was impressive,’ said Ayres, who is based at the Centre for Information Technology and Architecture in Copenhagen, Denmark. But this project and others like it were using fungus as a component in buildings such as bricks without necessarily thinking about what new types of building we could make from fungi.
That’s why he and three colleagues have begun the FUNGAR project – to explore what kinds of new buildings we might construct out of mushrooms.
Mushrooms might sound like an outlandish building material. But there is certainly good reason to drastically rethink construction. Buildings and construction are responsible for 39% of anthropogenic carbon dioxide emissions – and a whopping 21% of those emissions come just from the making of steel and concrete. Construction also uses vast amounts of natural resources. Take sand, one of the principal ingredients in concrete. It takes a special sort, with just the right roughness, to make concrete. These days it is a lucrative commodity and controlled in some parts of the world by sand mafias and stolen by the boatload from islands.
Such troubles are set to worsen over the next decades as the world’s population grows faster and gets wealthier. We need a lot more homes and if you do the maths, the amount we need to build is staggering. ‘It’s like building a Manhattan every month for the next 40 years,’ said Ayres, borrowing a line from Bill Gates.
Can fungi really help? Absolutely, says mycologist Professor Han Wosten at Utrecht University in the Netherlands. Fungi are not consumers of CO2 like plants are. They need to digest food and so produce carbon dioxide, like animals do. However, the organic waste streams (such as straw or other low value agricultural waste) that the fungi digest would be degraded to CO2 anyway, either by composting or burning. Plus, fungi bricks permanently fix some of that waste inside them and so act as a store of carbon. All this makes fungi buildings a climate win – and certainly miles better than using concrete, steel and bricks.
The FUNGAR project began in late 2019 and so far Prof. Wosten has been experimenting with how to make building materials. At Prof. Wosten’s lab in Utrecht, the team have been combining mycelium, the ‘roots’ of fungi, with agricultural waste such as straw. Then they allow the fungi to grow for about two weeks, until the fungus has colonised the straw. This binds the straw together, producing a white-ish foam-like material. Then they heat-treat it to kill the organism. They can also process it, for example by applying coatings or by squashing it. ‘If we press it we can get a material like hardboard,’ said Prof. Wosten. By varying the type of fungi and agricultural waste, the growth conditions and the post-processing, Prof. Wosten says they are getting all sorts of candidate building materials with different mechanical properties.
‘It’s very early days to start saying your house will be made entirely of fungus,’ said Ayres. But parts of it already can be. Mogu, a company based near Milan in Italy, already produces and sells sound-dampening velvet-textured wall tiles and floor tiles based on mycelium foam. The company’s chief technology officer Antoni Gandia is another FUNGAR project partner. He said that Mogu is also developing mycelium-based insulation material for buildings.
Ayres is hoping that the FUNGAR project will go way beyond just using fungi-based products as components in existing building designs. He wants to think about what entirely new kinds of building might be made from fungi. Foremost in his mind is building with living fungus.

There are two principal advantages to this. First, living fungus might behave as a self-healing material, simply re-growing if it becomes damaged. Second, mycelium networks are capable of information processing. Electrical signals run through them and change over time in a manner almost akin to a brain. ‘We’ve discovered that fungal materials respond to tactile stimulation and illumination by changing their patterns of electrical activity,’ said Prof. Andrew Adamatzky at the University of the West of England in Bristol, UK, who is coordinating the project with Ayres.
The idea is that perhaps the very structure of a mushroom building might sense and respond to its environment independently. It might for instance sense when CO2 levels from the mycelium are building up and open the windows to release the gas, according to Gandia.
Building with living mycelium will be a big challenge. This is because the longer it grows, the more of the substrate material – the straw, or whatever waste – it decomposes. Since the straw gives the materials their structural integrity, allowing the fungi to grow for too long isn’t desirable. There may be ways around this though. Depriving the fungi of water puts it into a dormant state: alive but not growing. And so one of Ayres’ ideas is to construct walls with two layers of dead fungus enclosing a layer of living fungus inside. This set up would shut out water from the inner layer, keeping the fungus there dormant.
One of the few other people who have explored working with fungi in construction is Jonathan Dessi Olive at Kansas State University in the US. He says that working with living mycelium is a very interesting new idea because it offers the possibility of the building being able to heal itself. But for him the real attraction of what he calls ‘myco-materials’ is that they ‘give us a way of reshaping how we think about the permanence of architecture.
‘What if some – not all – of our buildings were meant to only last a couple of years and could thereafter be recycled into shelter, food, or energy?’ he said.
The next major goal for the FUNGAR project is to build a small, freestanding building. They plan to pull that off within a year and then spend time monitoring it as it ages. It is crucial, says Ayres, to be able to monitor the living structure and see how it changes. It isn’t yet clear exactly what sorts of structures might end up being made from fungi, but they will probably start small. ‘I wouldn’t be crossing a bridge made of fungi, would you?’ joked Prof. Wosten.
You might be wondering what happened to Hy-Fi, that igloo-like structure in New York. The answer points to one of the most beautiful things about mycelium buildings. No wrecking ball or slow decay for them. It was taken down and composted.

Cemeteries not only provide a peaceful place to commemorate the dead, and observe and enjoy nature; they are also wonderful repositories for the study of local history and art. But that’s not all. Cemeteries also offer an easy introduction to science that anyone can enjoy.
A visit to a cemetery presents a wonderful way to learn about geology and the other sciences, such as chemistry, physics and engineering, that underpin it. For geologists – whether amateur, student or professional – almost any urban cemetery provides a valuable opportunity to carry out scientific fieldwork at leisure, right on the doorstep, and at no cost.
Geology on show
Because gravestones are made from a wide variety of rock types formed in a range of geological settings, cemeteries can be geological treasure-troves. Many headstones are made of polished stone, so reveal details – such as minerals and crystal features – that are not easy to see elsewhere. Some demonstrate the textures and mineral composition of igneous rocks – rocks formed when molten magma cooled and solidified. Others are happy hunting grounds for lovers of fossils. Some gravestones reveal sedimentary structures that show how the rock was originally deposited. Others provide clues to earth movements and environments that occurred hundreds of millions of years ago.
For those interested in engineering, examination of gravestones can also provide useful information about topics ranging from weathering of stone to atmospheric chemistry, effects of pollution, stability and settling in soils and land drainage.
Cemeteries in Oxford include ancient churchyards, such as St Andrews Headington, as well as Victorian cemeteries like Holywell (pictured top) and St Sepulchres, and more modern burial grounds, such as Headington Municipal cemetery. Together they exhibit the main features and stone types that can be seen in cemeteries all around Britain.
In the short video below, filmed in the churchyard of St Mary and John in Oxford’s Cowley Road, Philip Powell and I introduce the basics and show you how to get started in exploring these geological gems. If you want to learn more, visit www.gravestonegeology.uk. But be warned – gravestone geology can be addictive. Once you’ve got your eye in, you’ll never look at cemeteries in the same way again!
We have an ambitious project underway at the Museum, to preserve a unique and scientifically important collection of over one million British insects. It’s called HOPE for the Future, after the Hope Entomological Collections, and we are keen to shout about how these specimens can help us understand biodiversity, habitats and ecologies.
The learning team behind the project are today launching a new blog for young people interested in entomology. Intriguingly, it’s called Crunchy on the Outside, but please don’t confuse this with the similar, but fundamentally different, mid-’90s advertising campaign for the Dime bar.
Crunchy will be crammed full of interesting insect info, fun things to make and do, a peek behind the scenes at the Museum, and news from people, past and present, who work in the field of entomology. The odd bad joke may also worm its way in (What do butterflies sleep on? Cater-pillows).
The blog will also be a platform for young people to have their say, about the topics covered on Crunchy itself, as well as on the activity of the Museum. It will give them first dibs on access to related events too. You can check it out, follow, and share at crunchyontheoutside.com.
Elaine Charwat has been on a journey into the attic storerooms behind the scenes of the Museum to discover 19th-century wax models of parasites. A strange occupation you might think, but it’s all part of her doctoral research programme with the Arts and Humanities Research Council to learn about the use of models and replicas in science, past and present. In the podcast above Elaine meets Mark Carnall, Zoology Collections Manager at the OUMNH, who talks about the differences between models and the thousands of specimens he looks after, and Dr Péter Molnár, Assistant Professor of Biological Sciences at the University of Toronto, who offers important insights into current research using mathematical models.
Different types of models and replicas are everywhere in the Museum, and they tell us much about the organisms they represent or reconstruct, but even more about processes in research and science. Made to communicate and produce data, these larger-than-life objects are as fascinating as their subjects…
Top image: Wax models of Sarcoptes scabiei (itch mite) produced by Rudolf Weisker, Leipzig (Germany), probably late 1870s or early 1880s. These models are listed as having been on public display at the Museum in 1911, labelled: “Sarcoptes scabiei: enlarged wax models, male & female + mouth parts”.
When the campaign to build the Museum was launched, science at Oxford was understood as natural theology. By the time the Museum opened in 1860, a new secular approach to science was on the rise.
In this last episode of the Temple of Science podcast series we see how the art and science of the Museum responded to the challenge posed by Charles Darwin’s theories of evolution and natural selection, and the scientific naturalism that they epitomised.
