The CPS invited some professionals of industry to describe their experiences and the progress of their career. Pre-talk I spoke to a year 3 CPS member for whom this was the first CPS event they had ever attended. The reason was the simmering urgency found in the autumnal years of formal education, when the big bad world is looming over the horizon. A common question in my year group at the moment is: “What do you want to do when you leave University”. My retort; is sadly predictable. Ergo I need some careers advice!

If you are like me, long term planning is firmly entrenched in the back of the mind. Occasionally it surfaces with its frightening and profound implications only to be beaten back by more pressing and transient short term counterparts. Here follows a very short account of how the CPS guests persuaded its audience to entice into the forefront of their minds the idea that we possess complete control over our future careers.

In short, I wasn’t convinced that there is a paint by numbers method of securing the ‘perfect career’. All the speakers agreed that everyone is an individual, which accounts for our differences in what drives and motivates us. The RSC asked us “What does success look like for you?” Told us “don’t leave it to chance.” The career that forms most quickly may not be the most stable one. The speakers from GSK and Johnson Matthey represented those who had got their heads down in school and followed the research stream from university into the applied sciences of industry. They made it sound very straight forward and hopefully fuelled some fires in the crowd. The final speaker had a different take on things. The resounding idea in his talk is that we don’t have much control, that a whole ensemble of forces may disrupt our ‘plans’ and that the best thing we can do is to be prepared for change.

I came away wondering if I’m agile enough, flexible enough. Do I have the transferrable skills? Can I convince employers that I’m a safe bet? If you are wondering the same things then get in touch with UCL careers and they’ll tell you how to ace an interview and be the best you can be. Otherwise just try and do something you really love?

Here are some inspirational quotes from BBC’s ‘The Apprentice’.

If we went to Mars right now, I’d find a way to be excellent”

“My positive approach and very good looks make me stand out from the crowd.”

“There are two types of people in the world: Winners and… I don’t know how to say the word, I can’t say it.”

“I’m a ‘Great’ of my generation. I’m an innovator and leader in business. I take inspiration from Napoleon.”

 

Studying and Caring for Old Master Paintings: CPS Talk 14/10/14

By Penny Carmichael, on 24 October 2014

 

-Article by Stephen Leach

10321771_892836184060770_588734808802175067_oThis week the CPS were joined by Joseph Padfield, a conservation scientist at the National Gallery London. From ancient pigments to modern imaging techniques, the eager CPS audience where about to see through the eyes of a scientist charged with the upkeep of some of the UK’s most treasured paintings.

It began in 1823 when the Government bought 38 paintings for £57,000. In the following years the collection grew and so did the need for its preservation, the first steps taken were to move the entire collection from the Pall Mall to where it currently resides on Trafalgar Square, as Pall Mall was far too grubby for such an illustrious hoard. Air pollution was rather bad in 1800’s London and the first scientific consultation came from Faraday who noted that:

“A person of competent chemical knowledge might be valuably employed”

Now a full team of scientists reside in the gallery. They investigate painting materials and techniques; they are able to chart the weathering of artworks by natural or unnatural forces. They provide new ways of seeing the paintings and document the process of creation. Finally they employ non-invasive methods of preventative conservation.

Materials were treasured for their colours long before anything was known of their chemistry. Lapis Lazuli is a natural zeolite type base for the pigment Ultramarine. It has lent a glorious blue to paintings such as ‘The Girl with the Pearl Ear Ring’ by Vermeer and ‘Bacchus and Ariadne’ by Titian. Colours demonstrate great variety in nature and were among the first qualitative indicators of materials undergoing chemical change.

In some case tiny samples are taken from the surface of paintings in order to investigate exactly which materials where used and in which order. One of these tiny fragments ~ 100 µm provides a cross section of the pigment, the binder and the varnish. From these particles the researchers can discover what techniques were being employed and whether the surface of the painting is still representative of the artist’s original concept. For example, ‘The Portrait of Alexander Mornauer’ by an unknown artist, had undergone an unnatural change. Analysis of the fragment showed a blue colour had been added over a layer of varnish, beneath which was a brown colour. This blue, which made up the background of the portrait, was found to be a Prussian Blue pigment, which was not used until 300 years beyond the established time of creation of this work. It therefore proved that some other individual had painted the brown background blue. The supposed reason for this alteration is that with a blue background it could be passed off for a highly valuable Holbein. It has since been ‘cleaned’ and as a result Alexander Mornauer is represented as intended, with a slightly larger hat.

Light can be a big problem for paintings, but it’s useful when it comes to looking at them. In the 1800’s the paintings were lit solely by daylight, which meant the gallery closed on gloomy days. Now artificial light is employed in concert with natural lighting but great control is exercised over the spectral range and intensity of the light. Some works of Mark Rothko are destined to slumber in dark storage as a result of the extreme light induced fading that the pieces were undergoing. Unfortunately colours may fade over time, the chromophores in organic pigments break down. In ‘The Rokeby Venus’ by Velazquez she now reclines on a sheet of dark grey which was once a rich purple. Painted foliage can appear blue instead of green as the yellow breaks down in the mixture. The fading of vermillion has been linked to trace chlorine quantities, which is why on icy days you’ll not find NaCl scattered on the floor around the National Gallery. The gallery employs LED lighting which has the least possible emission in the UV region and couples this with an automated shutter system on the windows which changes its position minute by minute in accordance to the time of day and year.

Finally we learnt how modern technologies have allowed new insight into how we see paintings. Once X-ray images were producible, it was not long until paintings were irradiated, the first instance being in the 1920’s. This exposed the guts of a painting, for example how canvasses had been patched together, how artists had painted over old works or made subtle changes to detail. For example, in the painting ‘Young Woman Powdering Herself’ by the pointillist Georges Seurat, the artist originally included a self-portrait, which for reasons unknown he decided to cover over with flowers. X-rays reveal that he is still there, peering out from behind the bouquet.

The Gallery also employs an automated image capture procedure which produces exceedingly high resolution images of the works. With such techniques, the 3D contours of the surface can be recorded so that the painting resembles a bas relief, making every brush stroke and indentation traceable. Digital capture of the artworks not only aids study of the pieces but also enables them to be reproduced and shared more widely than ever before.

Careless Scientist Turns Into Fly: CPS Talk 07/10/14

By Penny Carmichael, on 14 October 2014

-Article by Stephen Leach

1554528_890561334288255_3712353249321162351_n

This week there was no CPS lecture. Instead, entertainment came in the form of ‘The Fly’ by David Cronenberg. It’s a 1986 sci-fi horror masterpiece in which Mr Cronenberg charts the epic destruction of a brilliant scientist played by Jeff Goldblum who became perilously entangled with the common fly. This film explores how the initial improvements which accompany a scientific breakthrough are followed by dangerous uncontrollable consequences. Much like the martyred Miles Dyson, the computer scientist who created the circuitry that would go on to become the twisted brain of ‘The Terminator’. In the Terminator franchise, robots became so advanced and clever that they wanted to destroy the foolish humans who created them, (all time travelling paradoxes aside).

 

Yes these technologies are make believe and are accepted for dramatic effect. However the underlying theme has some reality. There is probably a quote from Jurassic Park which could sum up everything I’m getting at here but that would be too simple.

The question is: do science researchers inherit a greater amount of moral responsibility during their training than they sign on for? The film industry certainly says ‘yes’. The mass media says ‘yes’. Scientific findings are reported to the general public via news agencies with minimal reference to any of the assumptions made or experimental context. Once in the news, those findings from a controlled environment go on to directly influence people!

 

History also agrees in one very extreme case, which is depicted in a 1980 documentary by Jon Else, ‘The Day After Trinity’. Freely available online, it features a collection of interviews with people who had worked on the Manhattan Project or knew J. Robert Oppenheimer. Fifty years on from Hiroshima 1967 Nobel physics prize winner Hans Bethe, head of the Los Alamos Theoretical Division remarked “Individual scientists can aid nuclear disarmament by withholding their skills…” Even to discuss the weapon they created is to enter into a sticky moral debate.

 

As a chemistry undergraduate the closest I get to a moral issue is the use of excessive amounts of water in the teaching labs, or by accidentally misusing the waste recycling facilities around campus, (thankfully the chemistry department is addressing the former and I’m paying closer attention to the bins). Most people, researchers or otherwise will get through careers and life without becoming embroiled in any serious moral dilemmas. Is that due to a lack of them? Or due to a haziness around accountability and how empowered or disempowered we feel when faced with one? You only have to enter a supermarket to be faced with an ethical decision and discover that our system allows the ‘ethically sound’ shopping basket to cost more than its battery farmed equivalent. Stop giving me the choice to be morally lazy!

 

I’m confident that the majority of students embarking on scientific educations are striving to make the world a better place and trust in the academics we’ve encountered here at UCL to help us do so. Scientific research does transform society for the better. The more scientists delve into non quantitative moral issues, the more religious/political leaders cease to be the sole governors of morality.

 

Personally, I don’t even have the guts to tell someone to pick up their litter. ‘Doing my bit’ for society involves a highly expensive and long education. Thus are the complexities of procrastination.

 

This blog entry by the film maker Adam Curtis via the BBC has discussed this theme far more coherently than myself (or Jurassic Park), so take a look for some food for thought:

 

http://www.bbc.co.uk/blogs/adamcurtis/posts/THE-VEGETABLES-OF-TRUTH

 

He says:

 

Science and scientists do all kinds of wonderful things. But when they venture into the social and political world they tend to get bent the way the ideological wind is blowing.”

 

If scientists are not bent by the ‘ideological wind’, then are they not at risk of ignoring the society which they are meant to serve?

Rhythm and Base Pairs – CPS Talk 30/09/14

In the first of the weekly CPS talks this year, Dr Adam Rutherford visited the UCL Chemistry Department to discuss the unlikely companions of genetics and hip hop. As a conscientious biologist and geneticist he opened with a cautionary tale about incest. The Habsburg Dynasty of Spain (who ruled Spain between 1516 and 1700) had a family tree resembling more of a family web. ‘The Habsburg Jaw’ was their treasured facial feature and for this distinctive chin they risked the fertility and health of their descendants, inevitably ending their reign. Charles II, the last Habsburg, died heirless at 38; his jaw couldn’t save him. Genetics is hinged on the relation between the genotype (the genetic material) and the phenotype (the physical result of the expression of the gene). Hence the Habsburg Jaw is the phenotype for the expression of one or many genes which had been intimately shared around the family. In their defence, Dr Rutherford concluded the tale by reminding us that nobody is perfectly outbred.

Once this connection had been made, the curious scientist wondered about the possible transfer of genetic material between organisms in order to control novel unnaturally occurring characteristics. This is not a new idea; The Chimera, (a hybrid animal which is composed from parts of others) was originally found in Greek mythology and is often used in heraldry. ‘The Enfield’ for example, a chimera with the head of a fox, the body of a lion, an eagle’s talons and the ass of a wolf appaears in the London Borough of Enfield’s coat of arms. Human-like chimeras are found in H.G. Wells’ 1896 novel ‘The Island of Dr. Moreau’, which questions of how far science should interfere with nature, although it was vivisection at the time which had inspired its plot.

When Darwin wrote “The Origin of Species”, he chose to tread fairly carefully; he personally didn’t want to initiate a full renegotiation of the prevalent religious doctrine of the times. Hence the book opens with a chapter on Pigeon Fanciers, entitled “Variation Under Domestication” and presents incredibly lucid argument for his theory in the context of the controlled breeding of pigeons, which was at the time ubiquitous. The breeders select the phenotype they wish to preserve and allow that individual to breed; unnatural selection. If the phenotype was being preserved, then so must the genotype.

In nature, genetic material can be mixed by breeding or by the mechanisms of viruses, but in the modern laboratory genetic material can be shared with much greater control. Examples were given of some amazing current technologies: a plant which has been genetically modified to grow purple instead of green when in the presence of land mines. Yeast cultures which secrete diesel. Genetic logic based circuits which ‘calculate’ whether a cell is cancerous and if so, instruct it to kill itself.1

Finally that brings us to the hip hop analogy which serves to illustrate the idea that the progress/development/evolution of ‘a thing’ is propagated by the sharing or transfer of material. This analogy takes flight upon the recognition that early hip hop was built on samples, that is, pre-recorded music from another artist re-expressed in a new context resulting in a novel characteristic sound. The reorganisation of material had enlivened and enriched the final product, making it ‘fitter’ than its competitors. The creators of the chimera were DJ’s of the dark ages, mixing not beats but beasts. Darwin’s pigeon fanciers are like music producers, tuning and honing not the beats but the beaks and breasts.

As for the modern examples, the analogy changed. Genetic research brings with it ethical problems, while at the apex of hip hop were legal problems. In order for hip hop to become the hugely lucrative enterprise it now is, there had to come a restriction on the sharing of material, ownership and licensing were ushered in; survival of the richest. Dr Rutherford suggested that this meant the end of the genre, having lost its mechanism to freely exchange material. Although perhaps ‘speciation’ had taken place and the genre has not died, but changed its habitat. A similar struggle occurred in the biosciences as companies attempted to become legal owners of genetic material. Thankfully this has yet to occur. In genetics and hip hop such restriction could be considered stifling.

Dr Rutherford’s favourite rapper is Tupac Shakur, that’s an exclusive. However he chose to conclude with a quote from the American activist and Professor of Law; Lawrence Lessig:

“A culture free to borrow and build on the past is culturally richer than a controlled one.”

Diamonds are a Chemist’s Best Friend – CPS Talk 04/02/14

By Penny Carmichael, on 21 February 2014

UCL’s own Professor Paul McMillan takes us on a journey to the centre of the earth in search of the weird and wonderful chemistry that occurs at high temperatures and pressure with a smattering of biology too.

 
Everything you know about chemistry is only true under specific temperatures and pressures. We do our chemistry on the outer surface of the earth’s crust, where the temperatures vary in the range of a few hundreds of degrees and pressure is around 1 atmosphere which is 100 kPa. Here the periodic table works rather nicely and the fits with the observations we can make. But what happens if we go deeper? The largest hole ever drilled goes down about 12km, not even breaking through the crust into the mantle. If we could somehow reach the Earth’s core we could do experiments at 7000°C and at a pressure of 360 GPa.
 
And why should we care about this? To understand planets. For example, the centre of Neptune has been worked out to be at around 800 GPa due to its large size. And as we know it’s composed of methane, water and ammonia, what do pressures as ludicrously large as that do to the chemistry of these molecules? How do they interact with each other? Professor McMillan’s lab is interested in the weird chemistry of high pressures and temperatures. They do this using the not-so-humble diamond.
 
Diamonds are thrown up from the mantle in places like South Africa where the earth’s crust is very old. Diamonds are formed from graphite that is put under the high temperatures and pressures found 120 km below the surface. They are forced upwards by pressurised gases and mechanical weaknesses in the rock to where they can be mined. But what if we could make them ourselves? The artificial diamond was created thanks to advances in pressure seals made by Percy Bridgman, who won the 1946 Nobel for his work. These high pressures (around 25 GPa) allowed General Electric to create the world’s first artificial diamonds and more have now been produced in a high throughput process than have ever been mined. But what about pressures higher than 25 GPa? Let’s throw diamonds at the problem. By putting two flat ended diamonds together in a vice, whatever is between them is crushed with a pressure of ~400 GPa. And thanks to the transparency of diamonds, you can heat your samples up with a laser!
 
The diamond anvil press has been used to investigate the changes in rock structure that occur with depth into the earth. Silicates make up the majority of rocks on earth and exist in a 4-coordination state at the upper mantle but are compressed into a spinel form as it goes further down into the mantle and then finally a 6-coordination state before it reaches the core. A current debate is raging in high pressure chemistry over the state of hydrogen under high pressures. It’s possible to grow crystals of hydrogen, modelling the high pressures inside Jupiter. But it’s controversial whether or not this crystalline hydrogen is metallic or not, with some labs showing conductivity under shockwave pressure (using essentially a battering ram) but this hasn’t been replicated in the diamond anvil. However, elements like Iodine do become metallic at 20 GPa and superconducting too. It would in fact appear that all elements are superconductive above 100 GPa.
 
And what about biology? The bottom of the Mariana Trench, 10 km below sea level, is at around 100 MPa and is teeming with life.  These are piezophiles, incredibly hardy organisms that have adapted to extreme pressures. But can we recreate this in the lab? Professor McMillan has created piezophilic E. Coli by culturing them in the diamond anvil and gradually increasing the pressure. This form of natural selection is a model of adaptation driven by an outside stressor, another of which is antibiotic resistance. Hopefully the mechanisms discovered in these pressure experiments will be useful in the fight against antibiotic resistant pathogens.

Chemist Wins Public Engagement Award for SuperLAB! Event

SuperLAB! to the rescue! Having fun at the SuperLAB! event.

Walking into a Shoreditch bar on a Wednesday evening, the last thing you might be expecting is a CSI crime scene and lab ready for you to play detective. The free ‘SuperLAB!’ events were inspired by crime and superhero comics and ran over the course of two nights. Artists and scientists came together to organise activities and discussions for punters at the bar. On the first night, ‘Draw’, artists, psychologists and neurologists demonstrated the art of comic books, how art has come to influence science, investigate what makes a person have the ‘right’ brain for art and whether chemicals can expand the creativity of artists. ‘Crime’, the theme of the second night saw psychologists and scientists focusing on how the crime was performed, what makes a devious villain and most importantly, the modern forensic techniques used to catch them!

One half of the SuperLAB! bid team, Nadia Abdul Karim, has recently won the ‘Student Engager of the Year’ at the Provost’s ‘Public Engagement Awards’. During a break of unnecessary email checking at work, Nadia had decided to respond to an ad about the project. One thing led to another and she managed to successfully co-bid for a grant to fund the two evenings. As someone who has organised a few smaller events, I can appreciate the time and hard work that Nadia had put into not just the demonstrations, but also sourcing equipment and managing students for such an ambitious event.

Nadia Karim (right) receiving the ‘Student Engager of the Year’ award from the Provost (centre). Congratulations Nadia!

Like most PhD students, Nadia is fuelled by a desire of answering questions of how’s and why’s. After completing a Forensic Science undergraduate degree, she decided to join UCL’s Crime and Security Science DTC program looking at explosives. Explosions might sound exciting but the slog of research can take its toll on even the most vivacious of students, losing sight of how and why we are doing a PhD.  Research students experience this everywhere after looking at, as Nadia puts it “an endless list of negative results”. She is optimistic however, enthusing that engaging with the public can be powerful fuel, “it helps you realise that research goes beyond the lab and office, and it does affect and interest the wider public.”

The award of student engager wasn’t just received for the coordination of the ‘SuperLAB!’ event Nadia also participates in one-off events such as outreach at schools, open days at the Institute of Making and public taster lectures. She has also taken on roles of being a student and ‘Brilliant Club’ mentor. Even just thinking about this many commitments has made my head spin; I had to ask Nadia how she does it. It turns out she is just a ‘Yes’ girl; “I sign up to doing all of these things, then realise I have a ton of university work to do at the same time and then somehow manage to be super-efficient (usually with the help of caffeine) to get everything done”.

Showing signs of self-deprecation, Nadia admits to not having any great planning or time management skills, just being an effective worker under pressure. Perhaps it is more than just organisational skills, thinking back to one my first encounters with Nadia at a dinner, she strikes me as having a genuine interest in society and people. Combining her sense of social responsibility with a scientist’s curiosity certainly makes Nadia an ideal, exciting and valued science communicator.

“Physics is like sex: sure, it may give some practical results, but that’s not why we do it”

-Richard Feynman
 
CPS’s second talk of the new term starred Professor Sir Michael Berry from the University of Bristol. His talk explored the interconnectedness between science and technology. Professor Berry’s talk consisted of several examples of physical concepts being used to create new technology that changed the world. But he also spoke of the opposite process, the new science that was being done thanks to advances in technology.
 
His starting example was the CD player, first introduced in the early 1980s. To read a compact disc you need a way of decoding the digital pits and troughs and this is done with a laser, first invented in 1958. The laser itself was based on the ideas of Einstein in 1917.  In his paper he defined three different fundamental interactions between light and matter. Photons of light can excite matter, this is absorption. This excited matter can then release a photon whose energy is proportional to the drop in excitation, this is spontaneous emission. What makes a laser possible is stimulated emission, where a photon hits matter that is already excited, releasing two photons. This cascades and eventually forms a coherent beam of light. This can be shone on a compact disc and detected. The digital signal is then converted into an analogue electrical signal and broadcast. The point of this all being that Einstein had no idea that his theoretical concepts would bring about the laser and the engineers that built the laser had no idea that it would be applied to music. These connections were all unexpected!  
 
Photography owes its creation to a wide number of talented  people. The photographic negative, where light causes a chemical reaction that can be fixed and then projected, was invented by Fox Talbot. Talbot had the idea when attempting to sketch a picturesque Italian vista. Not particularly talented, he resorted to using a camera lucida, a draughtsman’s device that projected the image on to paper for the unaccomplished artist to trace around. Unimpressed by his efforts, he wished that he could somehow fix the projected image in place. And several years later, after a lot of tinkering, he did. The film camera allowed people to see the entire world from pictures and invented the art of photography, all thanks to chemistry and optics. Of course, modern digital photography owes itself to science too as the ubiquitous charge-coupled devices are an application of Einstein’s photoelectric effect, published in 1905.
 
Professor Berry has done some interesting research on “Oriental Magic Mirrors”. These are cast and polished ornamental bronze mirrors with a deep pattern cut into the back. The magic comes by how the pattern on the back can be seen by reflecting light from the front of the mirror onto a surface and can be seen as a sharp image independent of the distance. This was discovered to be due to microscopic dips in the mirror due to the casting process of around 400nm. These were simply observed with a digital camera and analysed with commercial software. This is an example of how theorists like Professor Berry can simply do their own research using modern technology. The magic mirror phenomenon is now being used to analyse irregularities in silicon semiconductor manufacture.

Chemists Go Green

By Penny Carmichael, on 15 January 2014

bright-green copy

In the UK a new initiative has been set up with the aim of accrediting departments in universities on their environmental impact. This scheme is called the Green Impact Scheme and it aims to encourage progress and good environmental citizenship within university education. There is nothing quite like competition to encourage progress (and this scheme does just that) by setting up inter-departmental competitions within universities. The currency is a range of awards, for action plans which improve the environmental impact of each department and these are banked using an online workbook. Furthermore, to stoke participant’s creativity, special awards are given for unique projects which have been implemented as opposed to those which are already in the workbook. These unique projects encourage the discipline of each department to flourish and be shown be translated in the green impact work. For example, a biology department planting a wildlife garden (fat chance of that in central London where a square meter costs an arm and a leg). The scheme at UCL is run by the sustainability department. In the spring of next year, ambassadors for the department assess the implementation of the awards proffered in the workbook by each green impact group, and then the results of the Green Impact competition winners are announced.

The chemistry department of UCL has a Green Impact team which grows in numbers every week and consists of research students, staff and undergraduates. This team is a true representation of the departmental demographics, and so the effects are far-reaching. Weekly meetings take place in the Nyholm room on Thursdays between 1 and 2pm, where this team plots and plans to tackle the latest green issues in the department of chemistry.

The last two years have seen the department for Civil Environmental and Geomatic engineering take the winning spot within UCL. Of course, this discipline is implicit in positive environmental impact, but, no less so than the discipline of chemistry. Environmental chemistry, for example, is a field of chemistry in its own right, responsible for the discovery of DDT and CFC’s, detrimental substances which are now banned. James Lovelock, one of the leaders in the field of climate-change science, and founder of the Gaia theory, was a chemist himself; so, chemists are vitally important in environmental impact projects and hence great contenders in this competition. Green Impact actions we instigate could even lead to pilot schemes which become universal.  Indeed, a project which bring’s more improved and more environmentally printing has already commenced in the department. For an even greater impact, we should seize this opportunity to start disseminating our chemical wisdom and start to lead climate change action by example. This is the long-term aspect to this scheme. Most importantly, we aim to cause a modest revolution in the way that we perform chemical research and teaching on a day-to-day basis, and who knows, maybe one day there will be a roof-top garden/ laboratory.

Following the chemistry summer fun of the last squash tournament organised for computational and physical chemists, we extended the invitation to the whole range of staff and postgraduate chemists for Christmas. The setup of the tournament included a mini league and ending with knock-out rounds getting everyone fit and tired with so many games to play. This time the legendary squash-playing Prof Graeme Hogarth participated and easily obtained the gold. All this during his last week at UCL after 25 years! Good luck Graeme! This tournament marks the beginning of a chemistry squash league to start next year, when is still to be confirmed, but remember this is open to everyone- skilled and beginners, male and female, organic to physical and will hopefully be a league to continue for many years. So get involved!

– You can shed a few of those Christmas pounds by participating in the UCL Chemistry squash ‘ladder‘. All levels of playing ability are welcome. Contact Marion for login details.

Bones of Contention – CPS Talk 12/11/13

This week the CPS went on a trip out – but just round the corner. The Grant Museum of Zoology is the only zoological museum in London. We were given a lecture on its history by the curator Mark Carnall.

The Grant Museum first started life as a teaching collection for Zoology students and was founded in 1828 by UCL’s first Professor of Comparative Anatomy, Robert Edmond Grant. In his long scientific career Grant worked with both Darwin and Richard Owen. His main interest was sponges and he was the first to identify them as animals. At the time of his death in 1874 the collection contained 10,000 specimens, which has since been expanded and reorganised by later Professors and now contains over 67,000 specimens.

The collection was intended for medical students as at the time comparative anatomy was part of the medical curriculum. With the advancement of molecular biology, zoology fell out of favour and universities and hospitals began to throw out their collections and they were eagerly accepted by UCL. In 1996 the collection went public as the Grant Museum. The museum moved to its present location in the Rockefeller Building in 2010, the entire move taking 8 months. It regularly holds educational workshops with schools and can be hired out for conferences.
 
Only 3% of the entire collection is on display at any one time. This includes the skeleton of a Quagga, an extinct animal similar to a zebra of which there are only 7 specimens in the world.  There is also a skeleton of a Tasmanian Tiger. Arguably the museum’s most popular specimen is its jar of moles – 18 moles to be precise, stuffed in a large glass jar. No one knows why so many moles or why they’re in a jar. But somehow they’ve captured the public’s imagination and have an internet following and their own twitter account (@GlassJarOfMoles). An innovative use of the large collection of microscope slides is the Micrarium, where a former office has been converted into a lightbox covered wall to wall in slides. My personal favourite specimens are the skeletons of a human, a gorilla and a orangutan standing side by side on the balcony looking down at the visitors. The museum is a fascinating place with so much to see, it’s definitely worth a trip!
