Countdown to the 2014 Chemistry World science communication competition

1 December, 2014 - 14:06

Philip Ball, science writer and one of the judges for the upcoming Chemistry World science communication competition writes about the art of chemistry.

Philip BallOf all the sciences, chemistry has always seemed to me to be closest to the arts. It appeals directly to the senses: the shapes and colours of molecules, the smells, the tactile aspects of materials and instrumentation. It draws on intuitions and craft skills, for example in the practice of forming crystals or getting a reaction to work. And most of all, it demands creativity and imagination: ‘chemistry creates its own object’, as Marcellin Berthelot puts it.

Most of chemistry is not about discovering pre-existing forms and objects, but deciding what to make and how to make it. Molecular targets express ideas. Can we make something that fits into this hole or onto that surface? Can we create new atomic unions, unusual topologies, surprising bulk properties, new oxidation states? Can we design molecules to assemble themselves into new and useful (or simply pleasing or amusing) superstructures? The questions aren’t limited to what the natural world provides, but are circumscribed by our imaginations, which in principle need have no boundaries.

For these reasons, chemistry is perhaps the science most shaped by the personal styles of its practitioners, who are often regarded by their peers as artists of some description: Robert Woodward or Vladimir Prelog spring to mind, but everyone will have their own favourite stylists, whether they work on organics, inorganics, organometallics, polymers or whatever. There is a great deal of creative expression in the theoretical side of chemistry too: it is a science complex enough to depend on finding the right approximations, analogies and perspectives, on extracting concepts and approaches that are meaningful rather than being correct in some absolute sense. All of this makes chemistry thrillingly human, with all the argument, dissent, idiosyncrasy and flair that this entails.

Chemistry ought by rights therefore to enjoy the same kind of criticism and appreciation afforded to art – we can have views about what we like, even about what moves us. I suppose that this sort of subjective evaluation is not often encouraged because chemistry is a science. But it would be great to see some of it in this competition. The theme of ‘chemistry and art’ might be interpreted as ‘chemistry of art’, and there is plenty of interest in that. But it can also be read as ‘chemistry as art’. I look forward to seeing both perspectives explored in the entries.

Philip Ball is a freelance writer. He previously worked for over 20 years as an editor for the international science journal Nature. He writes regularly in the scientific and popular media, and has authored many books on the interactions of science, arts and culture. Philip also writes for Chemistry World and has a regular column – ‘The Crucible‘.

 

If you are passionate about science and science communication, the 2014 Chemistry World science communication competition on the topic of chemistry and art offers a fantastic opportunity to demonstrate your skill, win £500 and be published in Chemistry World.

Practised procrastination

27 November, 2014 - 18:01

Guest post by Heather Cassell

It’s an inevitability – there’s a task that should be doing but you can’t build up the enthusiasm. Normally mundane jobs can suddenly seem much more interesting to do.

For me it is always report writing. Although I love putting all of my results into order and writing it up succinctly for my colleagues and collaborators, I find I can rapidly lose focus. This is when the procrastination sets in. It never seems to matter how near the deadline is, how interesting my results are, or how important the document is – I feel an overwhelming desire to tidy my desk. ‘It’s important,’ I tell myself, ‘because if my desk is tidy I’ll have easy access to the papers and results I need to finish my report’. Just as a teenager’s room is never tidier than exam time, a researcher’s desk might only ever be clear when there’s a report to write.

Oh, but there are so many temptations! I’ve learned that when I’m meant to be writing a report it is best if I avoid the internet (see my previous post on the things you can discover while trawling twitter), so to physically remove the temptation often I’ll head into the lab.

But even the lab is full of potential distractions and procrastinatory aids, as there are always a diverse range of things to do! There is that pile of tip boxes that need refilling (it may have been gathering dust for weeks, but it seems urgent that they are to be filled and taken to autoclave). There are the consumables that need restocking, the buffers that need to be made, and stock solutions that need to be prepared. To the procrastinating mind, they all become more important than the task in hand. ‘If I’m not organised in the lab,’ I justify to myself, ‘then how can I work efficiently when I have finished my report?’

I try to reason with myself. I set targets and deadlines, promising myself a break if I can just reach the end of this section. As with exam dates and revision, eventually the deadline becomes so pressing that the level of stress rises and I actually buckle down to get on with the report.

It feels so good when it’s done that I consistently make promises to myself: ‘next time it will be different’; ‘next time I’ll just get it done without the distractions’. But the urge to procrastinate always returns. Who knows, without that urge my desk may never be clear.

Countdown to the 2014 Chemistry World science communication competition

21 November, 2014 - 11:05

In this first of a series of guest posts, Elizabeth Tasker writes about the how and why of her piece on cosmic chemistry, which was shortlisted in the 2013 Chemistry World science communication competition.

Elizabeth TaskerThere are some stories that beg to be written. When you find an experimental astrophysicist building a star-forming cloud in his laboratory, there is practically a moral obligation to remind the world that there are no boxes for ideas.

Astrophysicists usually come in three flavours: observers (telescope kids), theorists (‘The Matrix’ universes) and instrument builders (hand me a hammer). We cannot typically perform laboratory experiments since putting a star (or planet or black hole) on a workbench is distinctly problematic. The closest we come to hands-on experiments is through computer models, which is the toolkit I use when studying the formation of star-forming clouds. However, Naoki Watanabe had gone ahead and built his own cloud  in a super-cooled vacuum chamber.

What I liked most about Naoki’s work was the science question that was the heart of his project. Rather than take the tools of a given discipline and ask what could be learned, Naoki had picked the question and then drew knowledge he needed from astronomy, atomic physics and chemistry. This mingling of traditionally discrete subjects also made it a great fit for Chemistry World’s 2013 science communication competition theme of ‘openness’.

Discovering I’d been shortlisted was amazing. This feeling was briefly replaced by terror, since I was asked to produce a video clip describing my article as I was unable to attend the prize ceremony itself.

I recorded and re-recorded the video 10 times. All of them were identical. I feel there is a lesson to be learned about perfectionism that I likely failed to entirely grasp.

It was great to know that the judges had both enjoyed my article and were as excited as me about interdisciplinary work. Perhaps it is time to stop calling myself an ‘astrophysicist’ and simply say ‘scientist’.

Elizabeth Tasker is an assistant professor in astrophysics at Hokkaido University in Japan, where she explores star formation though computational modeling. Originally from the UK, Elizabeth completed her MSci in theoretical physics at Durham University, before pursuing her doctorate at the University of Oxford. Elizabeth keeps her own blog. She is working on a book on exoplanets (The planet factory), which will be published in 2016.

From Mould to Medicine

20 November, 2014 - 10:29

Guest post by Rowena Fletcher-Wood

Excited, Mary Hunt tipped out the produce of her shopping: a large moulded cantaloupe. She had come across the cantaloupe by chance, and the ‘pretty, golden mould’ had proved irresistible. She had discovered the Penicillium chrysogeum fungus, a species that turned out to produce 200 times the volume of penicillin as Fleming’s variety. It was a serendipitous discovery, and vital at a time when the greatest challenge facing medicine was producing enough of the antibiotic to treat all of the people who needed it.

Hunt’s finding has been barely noticed beside the original accidental discovery: Fleming’s return from holiday to find a ‘fluffy white mass’ on one of his staphylococcus culture petri dishes. Fleming was often scorned as a careless lab technician, so perhaps the contamination of one of his dishes – which had been balanced in a teetering microbial tower in order to free up bench space – was not that unexpected. But Fleming had the presence of mind to not simply dispose of the petri dish, but to first stick it beneath a microscope, where he observed how the mould inhibited the staphylococcus bacteria. Competition between bacteria and fungi was well known and, in fact, when Fleming published in the British Journal of Experimental Pathology in June 1929, the potential medical applications of penicillin were only speculative.

In 1897, a 23 year old French scientist, Ernest Duchesne, published his doctoral thesis on antagonism between moulds and microbes – specifically, Penicillium glaucum versus Escherichia coli. His insight into the healing power of penicillin extended as far as curing guinea pigs of typhoid, but his research was never recognised.

Fleming lacked the resources and chemical training to isolate and test the active ingredient in penicillin, so he handed his research over to pathologist Howard Florey in 1938. Florey quickly transformed his Oxford lab into a penicillin factory. However, even with the discovery of Penicillium chrysogeum, production was slow.

The first patients to formally trial penicillin were a cluster of 25 streptococcus-infected mice. Unlike their 25 less fortunate friends who were not given the new medicine, they made a full and swift recovery. In 1940, Oxford policeman Albert Alexander became the first human to take penicillin. Alexander was suffering from fatal septicaemia, but within 5 days of treatment he began to recover. Sadly, the penicillin ran out and as techniques at the time were unable to produce enough, Alexander died. Although it was widely administered amongst the troops during World War II, once again, production was limiting.

The real breakthroughs in penicillin production began shortly after the establishment of a new American lab; in particular, the casual introduction of corn-steep liquor, a by-product of the corn wet milling process. This was being mixed with a wide variety of substances in an effort to find a use for it, and was seen to significantly increase penicillin yields.

In 1942, Anne Miller, suffering blood poisoning after a miscarriage, became the first successful civilian recipient, but further tests were still needed to explore the range of diseases treatable by penicillin.

Horrifically, in 1946-8, the Public Health Service, Guatemalan government, National Institutes of Health and the Pan American Health Sanitary Bureau approved a study to infect prison inmates, asylum patients, and Guatemalan soldiers with STDs and treat them with penicillin. Over 1300 people were infected, and 83 died.

Today, penicillin is the most used antibiotic in the world, treating large numbers of dangerous diseases. It also has many derivatives, the discovery of which began in 1957, when John Sheehan developed the first total synthesis. Although the synthesis proved difficult to upscale, it nevertheless produced a 6-aminopenicillanic acid intermediate – the starting material for a whole new class of antibiotics. Although the penicillin you and I take is manufactured in a lab, the battle between fungi and bacteria continues, and you can still come across this world-changing substance naturally growing in its parent mould.

How to win a Nobel Prize, cover by cover

13 November, 2014 - 05:15

Guest post from Tom Branson

Last month’s Nobel prizes gave the world some new chemical heroes, but have also given me an opportunity to delve into the art of how to become a winner. Eric Betzig, Stefan Hell and William Moerner shared the prize in chemistry for ‘the development of super-resolved fluorescence microscopy’, which sounds, and indeed is, a very photogenic area of chemistry.

Through my exhaustive research of the prize winners’ websites, I found a handy list of journal covers on the Moerner group site. The other prize winners show off impressive lists of publications, but no helpful collection of cover art for me to plunder. So my apologies to Betzig and Hell: you may have Nobel prizes, but that doesn’t quite cut it here. Instead, let’s concentrate on Moerner and see what journal cover art can teach us about becoming a champion of science.

Moerner’s website shows nine journal covers, although it is not clear if this is an exhaustive list of the group’s artistic career. From this list, we can see that Moerner has a rough average of one journal cover per 38 articles published. Just for comparison, I’ve published a whopping three articles and had one featured on a journal cover, a much better conversion rate than Moerner. So does this totally non-scientific analysis suggest that I might be a dark horse for next year’s prize?

The most recent cover shown on Moerner’s website is from an article published last year in Nano Letters. A rather powerful magnifying glass is shown looking down at some fluorescing molecules and a large shaking arrow. A simple image that illustrates the crux of the work very nicely. There is more to see here than just pretty colours: the paper stresses the importance of analysing the oscillating behaviour of the molecules in order to achieve the best resolution with your magnifying glass microscope.

Another image from the Moerner group made it to the front of Nature Chemistry in 2010. Now this one, I really like. A pile of film rolls is shown with proteins captured in a new position on each frame, firing off bright reds and yellows. This is pretty much exactly what actually happens in the experiments. The camera-friendly proteins are very elegantly portrayed here on old Kodak film roll, probably because this is somewhat easier to imagine and more iconic than the digital storage relied upon in today’s techniques. The specific protein shown is allophycocyanin, a photosynthetic antenna protein that the group tracked, monitoring changes in florescence by using an anti-Brownian electrokinetic trap.

That same issue of Nature Chemistry features an editorial all about cover art. The editorial gave some tips as to what makes an attractive image and are open enough to admit that what really matters ‘is that you impress the editorial and production teams, who all get to have their say – and, in particular, the art editor.’ So just like the Nobel prizes themselves, where everyone has their own opinion, what counts in the end is to impress the judges.

The Nature Chemistry masterpiece wasn’t Moerner’s first high impact cover. Research from his group featured on the front of Science back in 1999 where some less-than-groundbreaking graphics, were used to highlight some definitely-groundbreaking research. His work has also featured on the covers of Nature Structural Biology and the Biophysical journal.

As for my own Nobel prize aspirations, I should aim to see my work on the front of a few more journals, for which I think I’ll need to publish a few more articles. I also assume the Nobel selection committee are not as easily dazzled by pretty pictures as I am. The road to Nobel prizedom may not be paved with covers, but showing off your artwork surely helps along the way.

If you come across some cover art that you believe to be prize winning material, or are simply seeking shameless self-promotion, then please get in touch with me in the comments or on Twitter (@TRBranson).
