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.

Yes, lockdown 3 is long but imagine being stuck on a boat for years on end with no TV, no internet and definitely no Netflix. Luckily, when Charles Darwin set sail on the HMS Beagle in 1831 he had access to a library of over 400 books on the ship. For Darwin Day, 12th February, we explored some of what Darwin read to help him pass the time…
As Darwin was following in the footsteps of earlier voyage naturalists, the Beagle library was well stocked with an excellent collection of books chronicling classic expeditions, such as James Cook’s three voyages to the Pacific Ocean (although this book is a later account of Cook’s voyages). Not only did reading about these earlier voyages inspire Darwin to undertake his own, but these accounts gave him insight into life at sea as well as fascinating details of some of the faraway places he was expecting to visit.
Many of the Beagle library books were beautifully illustrated with woodcuts or engravings of animals. Georges Cuvier’s, The animal kingdom arranged in conformity with its organization… (1827-35) had several volumes full of spectacular images covering mammals, birds, fish, reptiles, fossils, molluscs, crustaceans, arachnids and insects. While Darwin may not have had all 16 volumes with him on the Beagle, as some were published while his voyage was in progress, the numerous volumes Darwin did have access to would have provided a wealth of information and detailed illustrations to aid in species identification.
Using the vivid descriptions and chart in Patrick Syme’s Werner’s Nomenclature of Colours (1814) Darwin was able to identify the colours of the natural world and accurately record the colours of the plants and animals he encountered on his voyage. This beautiful pocket-sized taxonomic guide provided a uniform standard for colours that other naturalists would have understood and was an indispensable tool for Darwin in his scientific observations.
The most important book for Darwin was Charles Lyell’s Principles of Geology (1830-33). Darwin was gifted the first volume of the first edition by the Captain of the Beagle, Robert Fitzroy, as a welcoming present for joining the voyage. Darwin received the second and third volumes while in South America. In Principles, Lyell argued the earth is extremely old and the processes that changed the earth in the past are still at work today. Inspired by Lyell’s ‘uniformitarian’ proposal, this theory allowed for the longer time span Darwin believed necessary for evolution to occur.
Reading other books of exploration encouraged Darwin to chronicle his own voyage. His bestseller was published in 1839 as Darwin’s Journal of Researches. A revised 2nd edition was published in 1845 with a dedication to Charles Lyell and his “admirable Principles of Geology.”
This week my colleagues and I announced the discovery of a new species of mammal from the time of dinosaurs. It is one of two rare skeletons we’re studying from the Isle of Skye in Scotland. These mouse-like animals lived in the Middle Jurassic (166 million years ago), and tell us about the evolution of mammals in the time of dinosaurs.
The two fossils belong to Borealestes serendipitous and Borealestes cuillinensis. B. serendipitous was the first Jurassic mammal ever found in Scotland, known originally from pieces of fossil jaw found on Skye in 1971. In our new paper, we describe the skull of a partial skeleton of this species, found in 1972 by the original discoverer of the site, Dr Michael Waldman and his colleague Prof Robert Savage. But this exceptional fossil lay unstudied for over 40 years. Only now is it giving up its secrets thanks to powerful synchrotron X-ray scans, which reveal the anatomy in incredible detail.
The other fossil skeleton was found in 2018 by my colleague Prof Richard Butler. After taking it back to the lab and CT-scanning it, we realised it was a new species. We named it Borealestes cuillinensis in honour of the Cuillin mountain range on Skye (Gaelic: An Cuiltheann), a stunningly jagged set of peaks that overlooks where the discovery was made.
Most ancient mammals are only known from a few teeth and jaws, so these skeletons are exceptionally rare. They are currently the most complete Jurassic mammals described from the UK.
The Middle Jurassic is an important time in animal evolution, because it marks an increase in the diversity of lots of different groups. Just afterwards, in the Late Jurassic, there are many new species of mammals, amphibians, small reptiles and dinosaurs, which flourish into the Cretaceous period. All of this diversity began in the Middle Jurassic, but fossils from that time are rare, making it difficult to unpick the causes of these changes. This means that any material from that time period is extremely important to our understanding of the course of evolution, and the drivers of animal diversity.
Our team have been carrying out fieldwork and research on Skye for the last decade. It includes researchers from National Museums Scotland and the universities of Oxford and Birmingham. We are working on many more exciting fossils from the island, so keep an eye out for the next discovery!

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.
