New: The Dental Arcade Game

As you know, I am pretty keen on science communication and public engagement. Just in time for British Science Week, I am trying my hand at citizen science, with a new project called the Dental Arcade Game.

Its aim is to improve how forensic anthropologists (and odontologists) determine age at death from dental eruption. Usually what happens is that the anthropologist will chart the erupted teeth (ones that poke out of the gum) and the extent of eruption (how far the tooth has come up to meet the bite surface) of every tooth, and compare this to reference data in the literature to come up with an age range for that set of remains. The problem is that this reference data is quite out of date, and based on very specific populations, and so the age ranges provided may not be accurate.

The aim of this project is to amass a large amount of tooth eruption data (with age, sex and ethnicity) to increase the accuracy and improve the reference data that is used to base these age estimations on.

So...if you're interested, please take part in the survey. You can make a difference to modern forensic science! You can find out more on the Dental Arcade Game website.

Australian Human Taphonomy Facility

Happy New Year, lovely readers. I am sorry that I haven't posted since September - no excuse really, just very busy, as usual.

I want to draw your attention, if you're not already aware, to the recent establishment of a Human Taphonomy Facility (colloquially known as a "Body Farm") in Australia.

The idea of "body farms" or outdoor decomposition laboratories for human taphonomy research is not new. There are currently seven such facilities in the United States, and another one newly commissioned. One of the reasons for so many is that decomposition processes are heavily influenced by the surrounding temperature, humidity, species of insect and other environmental conditions, and so forensic scientists need to know how bodies decompose in their region's own particular conditions. This means that the data produced by US facilities is not always relevant or useful for other climates and countries.

The 12 acre facility, called the Australian Facility for Taphonomic Experimental Research (AFTER), has been created in bush land in the Blue Mountains area outside Sydney, and is intended to aid research into the impact of the Australian climate, fauna and insects on the processes of decomposition. This will prove invaluable for identification of unknown human remains, whether they are victims of homicide, misadventure or disaster.

The initiative has been headed by Professor Shari Forbes from University of Technology, Sydney (UTS), and funded by a Australian Research Council Linkage Infrastructure, Equipment and Facilities (LIEF) grant. It is a multidisciplinary, collaborative project that unites law enforcement organisations, forensic services and academic institutions. Partners include the Victorian Institute of Forensic MedicineUniversity of WollongongUniversity of SydneyUniversity of CanberraUniversity of New EnglandAustralian National University, as well as Victoria Police, Australian Federal Police, New South Wales Police Department and the Australian Nuclear Science and Technology Organization.

The terrain and vegetation are typical of areas commonly searched for human remains, and so it is a good mimic for a crime scene environment. Donated human cadavers will be used for the research, as there is no perfect substitute or analogue for human tissue, body composition and gut bacteria. Shari's research also uses pig cadavers (as we do in the UK at the moment), in order to determine how reliable pigs are as an analogue.

"At the moment, we're still not sure that pigs are the best model," she says, "and this will actually help prove or disprove whether or not pigs can be used as a model of [human] decomposition".

As a result, her research may have dramatic consequences for current forensic taphonomy research in the UK and Europe.

The facility will be used not only to push the boundaries of our knowledge of forensic science, including decomposition chemistry, forensic biology, toxicology, entomology and anthropology; but will also contribute significantly to our understanding of archaeological and geological processes, palaeontology, and soil science.

Personally, I hope that this initiative in Australia will pave the way for acceptance of such a facility among academics, forensic services, government organisations and the public in the UK. I strongly believe that a similar facility is necessary in the UK, as our climate, flora and fauna and environmental conditions vary significantly from the other body farm locations in the US and Australia, and without one, we will not fully understand the complex processes of decomposition and the interaction between human cadavers and the environment.

British Science Festival

I have just come back from the British Science Festival, which was held in Birmingham from the 6th to the 11th September. I was there as a British Science Association Media Fellow, which meant I had access to press conferences and embargoed news, the speakers' lounge and was allowed behind-the-scenes.

I arrived on Sunday, which was the family-orientated 'Community Day'. Birmingham University campus was humming with a carnival atmosphere. There were bouncy castles, flags, clowns, people on stilts, burger vans and ice-cream vans, like a fun-fair; but also more genteel marquees with sofas and potted plants, and canvas deck chairs outside in the sun, giving it a more 'garden party' ambiance. I saw a programmable humanoid robot, a man dressed as a skeleton and several science 'buskers' peddling their wares to enthralled children.

On the Sunday night, I listened to Professor Alice Roberts give a talk about her new book, 'The Incredible Unlikeliness of Being', which, while not new in terms of biology or embryology, was fascinating to watch. She is a compelling speaker and excels at explaining complex concepts in layman's terms. After that, I watched a hugely enjoyable talk by Professor Richard Wiseman, about the science of sleep. I learned that relying on your alarm clock to wake up is a sign of sleep deprivation, and it is best to sleep in multiples of 90 minutes. Between these two talks, I joined the Media Fellows' pub quiz, which obviously made a material difference, because we came second, out of about 25 teams.

On the Monday, the Media Fellows and I attended a press conference about an exciting Citizen Science project: the Big Bumblebee Discovery, which made me think of all the projects I could do... It was rather nice to see Dallas Campbell on the panel too.

I also attended a great session run by my colleagues at the British Association of Biological Anthropologists and Osteoarchaeologists about the bloodiest period in history, comparing the trauma found on skeletons from the Neolithic, Iron Age, Anglo-Saxon period and Medieval. I also saw another Archaeology and Anthropology session, 'The Ape that Walked', which offers an inference about how bipedalism may have evolved from arboreal locomotion on thin wobbly branches.

Overall, I had a fantastic time, not least because of the other Media Fellows in attendance, who are all brilliant, funny and super-intelligent. I came home brimming with ideas for public engagement in science events, large and small, for all ages.

The microbiome of death

Sadly, my Media Fellowship placement at New Scientist has come to an end. But, I rather feel like I have 'gone out with a bang', as my latest article for them is a double-page spread! (Not the same as a centre-fold, to my husband's disappointment!)

You can read it here.

I was very pleased to be able to write about something (a) I know quite a bit about, (b) I'm really interested in and (c) I'm passionate about. A lot of the time, I gather, journalists don't get to chose what they write about, so I was very lucky.

The microbes that colonise cadavers is just up my street, and it was great to interview Professor Peter Noble about his research - although I did have to disturb him during his Caribbean holiday [alright for some!]. He and his team looked at how microbes spread out from the gut and colonised different internal organs of several cadavers, as a function of time. They found that the microbe populations differed more between individuals than between organs, suggesting that colonising microbes may be used to identify people. Then talking to Sibyl Bucheli was really fascinating too, especially as some her research is very closely aligned with mine, and that of the Burial Research Consortium. She voiced certain caveats to the research that I was thinking but couldn't put in without an external reference, so it was very helpful to talk to her. I hope that we may be able to work together on similar projects in the future. And of course, it was wonderful to get some choice comments from BRC's very own Professor John Cassella, an expert in this field.

I really enjoyed seeing all the processes that go into transforming a spark of an idea into a full-blown article, and watch it being tweaked and polished by editors, sub-editors and back to editors again. It was great to see how pictures were chosen, or rejected as the case may be, and how my writing turned into a 'proper' article for New Scientist. I'm absolutely delighted!

From the trading room floor

Well, I am now into my penultimate week at New Scientist. The time has zipped past, in a blur of commuting on the tube, interviewing scientists on the phone, meeting deadlines and lots of writing and rewriting. I have begun to get the hang of things a little, and, if nothing else, learned how everybody likes their tea! So far, I have had eight pieces published, and hopefully have more to come. These have varied from short ‘reaction’ pieces to bizarre photos, to slightly longer, news-fuelled articles. I have also had a chance to get my teeth into one longer story so far, that is more forensic based than the others.

Here they are:

Actually, I have already learned more than I ever expected to. I now have insight into the dynamic between reporters, sub-editors and editors, and seen how stories get chosen or pitched to be articles for the magazine or online platforms. I am beginning to see the world through a journalist’s eye – examining ‘ordinary’ events for extraordinary angles, or trying to think of something that no-one else has thought of. It has made me appreciate how science gets published, blogged about and retweeted – it doesn't seem to be so much about the quality of the science – although that has to be sound – but it is more about whether the ordinary person can relate to it, and whether people want to chat about it down the pub. I have gathered that there is a clear correlation between the catchiness of a journal paper title and the chances of it being picked up by popular science journalism. So, if you want a journalist to do a feature on your research, you need to make it clear, easy to understand and emphasise how it affects real people. Basically, meeting the science writer half way will make the whole process much easier for both sides.

Facts are different beasts these days too. I have learned that they are a commodity to be traded, but the exchange rate is very steep. Scientists, or the fact ‘makers’, cherish the few true facts that they might be lucky enough to generate over the course of their careers. I, personally, have spent my academic career being careful not to accidently make incorrect ‘facts’, by avoiding making sweeping statements or jumping to conclusions, by being sceptical and reluctant to exclaim causal links between phenomena. Journalists are fact-hungry. They will procure several precious facts from a handful of different scientists before breakfast. Facts are – quite rightly – the bones of the article on which to hang the meat.


So, at first, my impression was that it felt a little unfair – that the fruit of the scientists’ labour is snapped up and guzzled very quickly. But actually, on closer inspection, it seems to be a more reasonable trade, as scientists relish the recognition of their work, and try hard to produce the sort of facts that people, and journalists, want to consume. Scientists just need to learn to take advantage of this, and start working more closely with journalists. And that, my friends, is just what the Media Fellowship is all about.

It's Day 3 in the New Scientist office...


Wow! I’m now three days into my placement and I’ve only just found some breathing space to write a post. New Scientist goes to print on a Tuesday, so when I arrived on Monday afternoon (not morning – don’t ask – nightmare journey), everyone had their heads down, furiously tapping away on their keyboards. The big open plan office was buzzing with typing and brains whirring. I was introduced to everyone, who all seemed very friendly but busy; given a desk and computer, and set to work finding a winning news story related to (luckily) forensic science. I won’t spoil the surprise, in case it makes it to the magazine or New Scientist online.

I was surprised at how difficult I found it to choose a piece of research that was (a) not too niche and esoteric only of interest to a small handful of academics, or (b) hadn’t already been plastered all over the headlines. This is really a skill that I need to acquire! I thought that a bit of insider knowledge would help, but it may even have hindered me slightly, as I was acutely conscious of what colleagues would say if I wrote anything remotely inaccurate.

The next day was particularly frantic, and really nothing like I’m used to in (relatively) slow-paced academia. Keyboards were smoking until at least lunchtime, but as I didn’t have a piece in the magazine that day and wasn’t under the same pressure, I researched a couple of other forensic stories, completed my Health and Safety induction and familiarised myself with the tea and coffee-making facilities. I was shown around the whole London office, which I was amazed to discover only contains about 60 people, who between them manage the ‘Upfront’ and bite-size ‘60 seconds’ news stories, editorial features, technological advances, careers, opinion and letters sections, as well as designing artwork, layout, online content and marketing. Talk about talented! And they do it every week!

By late Tuesday afternoon, there was a collective sigh of relief as “final copy” made it to the publishers, and a well-deserved pint was in order.

Only three days in, although I feel a little out of my comfort zone, I am really enjoying the difference between science journalism and academic research. Whereas the latter needs sound results and robust methodology, the former is more focused on finding an intriguing angle for each story, and although scientific accuracy is paramount, the human perspective is necessary too. I am loving the challenge, and hoping that I can learn to master the art of science writing.

Hitting the headlines

It must be a slow news day in Huddersfield, because I've made it into the Huddersfield Examiner for the second time in as many months! They've picked up the story of my recent award of a British Science Association Media Fellowship, and the fact that I will be doing a stint at New Scientist this summer.
Here's the article.
The previous article was about me joining the Forensic Science team at the University of Huddersfield and bringing the 'sexy' (their words, not mine) subject of Forensic Anthropology to the syllabus. I must say, I would have liked the opportunity to have another photo taken! However, I am delighted to say that there is a new MSc in Forensic Anthropology starting in September 2014. There are still places available, so get your application in!
