Language is often seen as a barrier to communication.  But sometimes it provides a valuable buffer between hearing, understanding and responding, and allows unique perspectives that are often drowned out to be heard.

A few weeks ago, I was interviewed by Brazilian TV presenter Luís Fernando Silva Pinto for the TV Globo program Ciência & Tecnologia on nanotechnology’s broader social and scientific implications.  As you would expect, when the documentary came out this week in Brazil, my very English segments were surrounded by a sea of Portuguese.  And having had a very “proper” English upbringing (i.e. I’m appallingly bad with other languages), I was completely at sea when it came to understanding how my comments were being framed.

Looking for some enlightenment, I asked the Brazilian-born Portuguese journalist Andréia Azevedo Soares (currently on sabbatical at Imperial College in London) for some help in getting a sense of what was being said in the program.  What I got back was a wonderfully candid running commentary on her response to the documentary.

Andréia’s notes were never written to be published.  But I found them so interesting that I asked if I could post them here – and she very kindly agreed.  In watching the documentary, she approached it both as a journalist and as a consumer.  And as a result, her comments shed considerable insight on how the story is presented, and how she as a consumer and Brazilian responded to it.

But the real beauty of her notes is that, because the documentary was in Portuguese, I was privileged to see it from her perspective – without the preconceptions, assumptions and biases I would usually bring to such a piece.  Very much a case of the message being found in translation!

The documentary – Nanotecnologia nos alimentos – can be viewed here (Update: thanks to Andréia for letting me know how to embed it):

Watching it, Andréia wrote:

0.0 Luís Fernando Silva Pinto picks the example of warnings on the cigarettes packages to make a parallel with nanotechnologies & food. When you smoke, you are fully aware of the risks you are taking. But what about food? He says: “If there was anything in your food that could be bad for your health, would you like to know? We are entering into the world of nanotechnology.” I understand the point the was trying to make with the parallel between labeling in tobacco industry and nanotechnologies, but putting it at the very beginning made me a bit scared. My body associated the smell of cigarettes with food that can be bad for me, and my head noted that nanotechnologies may have a role in this story. I am not sure about the connection between tobacco/food labeling (“If there was anything in your food that could be bad for your health, would you like to know?”) and the discipline itself in a broad sense (“We are entering into the world of nanotechnology”). The world of nanotechnology is not only about smelly evil foods, is it?

01.00 – 02.20 Luís Fernando says nanotechnology is becoming more and more a part of our lives – shampoo, soap and even equipment like the “electronic tongue.” I loved it! I’m now curious to know more about the electronic tongue. This is truly exciting. A scientist explains that a special layer can protect fruit and make it last longer. Luís Fernando asks questions like: “is it safe?” Andrew answers by explaining the uncertainties in the field (you have a plaster on a finger!) [You noticed!  The result of mishandling another “cutting edge” technology! - AM]. Luís Fernando says that even though we haven’t all the answers now, information provided by science will help us to control of and make informed decisions on our food. (Curious how science appears here as a solution to solve problem created by nanotechnologies – it makes me think about soaps made of greasy materials that clean… grease). I’m feeling more relaxed now. There are solutions in the pipeline. Luís Fernando uses words like “discussion” an “informed decisions,” and I feel empowered as a citizen.

02.20 Footage from Embrapa, in São Paulo [Embrapa is a research center connected to the Brazilian Ministry of Agriculture, Livestock and Food Supply - AM]. They produce new equipment and solutions focused on nanotechnologies applied to the farming business. It is said that this is a unique research centre in the world. I don’t know their work and feel excited about the science being done in Brazil. The reporter Flávio Ventura explains that they receive ground coffee from all over the country and they evaluate the quality of the product. Gustavo de Paula, an engineer (materials), introduces us to the “electronic tongue” and explains how it works. I love it! He says there are nano structures in it that can “taste” the coffee.  They complement the work done by the human taster – one thing is not going to replace the other. Gustavo de Paula explains things very clearly, I think I want to visit Embrapa at some point!

04.50 Details are given on what exactly the nano scale is, how scientists can “see” it, what equipment is required. The reporter says: “We live in a nano world but we simply are not aware of it.” He says that the pollen of flowers has a nano-metric element. He adds: “The proteins that make our body, and the DNA itself, is nano as well”. Then appears the nano specialist Eduardo Caritá, overexcited, saying: “The DNA controls all life in the universe – it is something with [a scale of] 2 nanometers. Do you think nature would have chosen this scale, this form, this structure if it were not the more efficient?” He conveys a lot of information in a very well-packed sentence (TV reporters probably love him), but I’m very very picky with DNA metaphors and get quite annoyed here. DNA is an inert molecule, it doesn’t control anything. Mother nature doesn’t have intentions, she doesn’t choose anything – things evolve. *eyes rolling* I take a deep breath and try to think Brazil is a country with almost 200 millions people and that TV Globo is a mainstream channel – it is amazing having a specialist talking about molecular structures on TV in such a simple and enthusiastic way. Language also evolves according to its context. Ultimately, the objective is to communicate. He does that very well.

06.00 New products. Nano-capsules that release chocolate flavors. Humidifiers that release rejuvenating particles (allegedly). The reporter says a brilliant sentence: “The nano world is becoming less and less invisible.”

07.40 Back to Embrapa. Engineer Gustavo de Paula stresses that *any* technology can do good or harm. “Nanotechnology is no different. We need to understand it at great detail to control the possible risks it might offer.”

08.05 Back to Andrew Maynard! Luís Fernando says you are a physicist, have studied in Cambridge (UK), and specialised a decade ago in this field. He adds that since 2005 you have been an active voice on regulation. And here comes the interview bit… [Andréia declined comment on my bits! - AM]

10.10 Back to Embrapa, focusing on fresh fruit and the film using nano-particles that helps to protect them from oxidation. The Embrapa researcher Odílio Assis explain that in Brazil nearly 50% of fruit are wasted during transportation and storing processes. He claims that this technology would ensure that 80% to 90 % of the crops effectively reach the sellers/consumers. The reporter says that the researchers are already sure about the safety of this anti-aging film for fruit, but they will do further toxicology research on it anyway. The Embraba researcher explains that nanotechnology cannot be understood as a single technology, and mentions that the nature of different particles should be taken into account. In that sense, an organic nano particle is different from a metallic one, he says. At Embrapa, he adds, they deal with natural particles obtained from a corn protein – so there is nothing to fear about, he suggests.

INTERVAL

13.30 Back to Andrew. Luís Fernando says that the lack of information is the main problem now. He adds that you believe that further and serious research is needed. And then comes the interview bit (I like the pink lamp on the desk) [It’s not mine - it belongs to a colleague.  Honest! - AM].

15.00 Fiocruz scientist William Waissmann says that we don’t yet understand all the possible outcomes of nanotechnologies, and adds that a great deal of their impact in humans remains unknown. Waissmann says there is no regulation on this matter in Brazil. He tries to be optimistic nonetheless, underlining that there are good scientists beginning to work in the field.

16.30 Luís Fernando says you believe science is in a position to provide answers. However, he says, you believe further and better research is needed and, therefore,  the  researchcinvestment should be more generous (figures are mentioned). I really enjoy your comments, they make me alert and willing to engage in the debate but not too scared. This is important. Scared people don’t engage in debates – they scream (I do, at least).

18.00 Back to Waissmann (I like the way he conveys the message – he says Brazil is completely unprepared to face nanotechnologies issues and, still, I didn’t panic yet). He says that people form opinions not only by gathering information from scientific sources but mainly from their cultural context (friends, small talk, etc.). He says that not as a problem itself but as someone who is trying to understand reality to better cope/deal with it. It did not escape my notice that all interviewees have good communication skills – and as a Brazilian citizen, I’m happy about this.

18.30 Back to Andrew. The silver Tupperware bit. I realise that there are too many objects behind you, Andrew.  I should not be paying attention to pink lamps and US flags – please try to do an uncluttering operation before giving interviews. You are infinitely more interesting and appealing than an US flag, but absent-minded people like me can get distracted with these details. [I should add in my defense that Luís Fernando decided to film me at a colleagues desk - I don’t normally surround myself with pink lamps and American flags! - AM]

19.30 Back to Waissmann. He underlines the possible effects not only on human health but also on the environment (I love it when someone tries to show things in a less anthropocentric way). He also explains why the same material can act differently depending on its form – the example given is comparing refined salt to coarse sea salt. Why has the latter less “power” than the former? I like the example but I suspect it covers the surface/contact/reaction bit rather than the fact that at the nano-scales particles behave differently (e.g. gold). But I am not the expert – he is and you are. And for the program, the example works brilliantly. He says that, in terms of toxicology, it is a new world we are entering in.

20.50 Andrew again.

22.20 Wrapping up. Luís Fernando says that it is up to us, consumers, to make informed choices. Even though the program finishes leaving me surrounded by uncertainties, I feel fine about the challenges to come. I believe it is difficult to talk about food safety and, at the same time, to leave an optimistic note at the end. I am curious to know more about the electronic tongue. I want to discuss what I’ve learned here with my partner as it is him who’s in charge of the supermarket duties.

I am deeply indebted to Andréia for taking the time to do this, for her candid insight, and for he willingness to allow me to publish notes that were never written for publication – thank you!

Andréia Azevedo Soares blogs at Bordado Inglês – in Portuguese.  She can also be followed on Twitter, where she writes about science, literature  language and the media (amongst other things) – and often in English

Update 4/26/10:  Corrected a few typos (including spelling Andréia’s name wrong – slapped wrists and big apologies!), and embedded the Ciência & Tecnologia video.

Hype, scare mongering, obfuscation and just plain misinformation – the scientific community are reasonably clear about what they think of Tabloid science reporting much of the time.  So I wasn’t too surprised to see the headline “‘Grey goo’ food laced with nanoparticles could swamp Britain” in today’s Daily Mail, following the release of a new report on nanotechnologies and food from the UK House of Lords.  Here we go again I thought – cheap misrepresentation to pull the punters in and never mind the fallout.  But on closer reading, perhaps this piece isn’t as crass and misleading as I initially thought…

Partly as a bit of fun, I thought I would deconstruct the piece, to try and work out whether there is some sense here behind the apparent madness.  But I also have a bit of a soft spot for its author, Fiona Macrae.  Fiona was largely responsible for educating me in the ways of Tabloid reporting a few years ago.  It was the launch of the Project on Emerging Nanotechnologies Consumer Products Inventory, and I was talking with a group of reporters at the UK Science Media Center.  I remember Fiona clearly – she was smart, engaged, asked intelligent questions.  I was effusive in my answers.  And shocked when I saw her story the next day.

Rather than telling my story, she told hers.  Under the banner “‘Hidden danger’ in anti-ageing cream” she appeared to take my carefully considered words and turn them on their head.  Of course, it didn’t help that, in the course of our amiable interview, I had told her “We are using humans as guinea pigs with a lot of this.”  The lesson: she was a skilled reporter, and I was naive!

Having been on the sharp end of her pen, I was interested to read today’s story with a slightly more dispassionate eye.  Here’s what I thought, section by section:

The headline: ‘Grey goo’ food laced with nanoparticles could swamp Britain

What an emotive headline – a new danger, infiltrating our food, and threatening to overcome us!  From a purely literary perspective, the imagery is wonderful – “‘grey goo food’” brings back recollections of old-style British cuisine, while “laced” and “swamp” are loaded with menace.  But is it inaccurate?  Placing grey goo in inverted commas tells us that this is shorthand for something, and not to be taken too literally.  According to the report the piece is based on, food could hit the shelves that contains nanoparticles (and is probably already there) – “laced” is descriptive, but not inaccurate.  Saying Britain could be swamped with these foods is a bit of an exaggeration – but it is possible that in the future significant numbers of food products could use nanomaterials in some way.  So while the headline is attention-grabbing, it avoids being plain wrong.

Britain is on the brink of a massive expansion in foods containing controversial ‘grey goo’ nanoparticles, according to the former head of the Food Standards Agency.

Low-calorie chocolate and beer that doesn’t go flat could be on sale within just five years, Lord Krebs said last night.

Is Britain on the brink of a massive expansion of foods containing nanomaterials – aka “‘grey goo’ nanoparticles”?  Not unless industry and government do something to ensure the safe and successful development of the technology, according to the House of Lords report.  But the statement isn’t too far from the truth.  And the chocolate and beer examples are accurate.

However, he and other peers believe there will be no requirement for the hi-tech products to be labelled as containing nanoparticles – microscopic compounds that can worm their way into the brain, liver and kidneys with unknown consequences.

Here we see the real skill of the Tabloid writer – technically correct writing with worrying embedded subliminal messages.  Sure the Lords writing the report didn’t believe labeling is the way to go – although they did come up with another solution to ensure people had access to relevant information.  And some nanoparticles can get to the brain and kidneys, with unknown consequences.  But by saying they ‘worm their way in’ Macrae conjures up images of slimy parasites and worse – would you want anything “worming” its way into your body?

But critics said the public have the right to know what they are putting into their bodies, and point out that new legislation will mean that cosmetics that contain nanoparticles will have to be clearly labelled.

Correct.  And the full report addressed this.

Once derided by Prince Charles as ‘grey goo’, nanoparticles are tiny particles – 300 million would fit in a pinhead – with powerful properties that make them of interest to food companies.

Although they are small, they have a large surface area at which key chemical reactions can take place. This means that relatively low numbers of sugar nanoparticles can have the same effect as a large amount of normal sugar, creating tasty chocolate or cakes with a fraction of the calories.

The same principle could be applied to fat, allowing the creation of low-fat icecreams and mayonnaise that taste like the real thing.

Nanotechnology-inspired packaging promises to improve food shelf-life, and in the U.S. plastic beer bottles have been lined with ‘nanoclay’ to stop the brew from going flat.

This is all good and useful information.  Having grabbed the Tabloid reader’s attention, Macrae is now feeding them some useful information.

Lord Krebs chaired an inquiry by the House of Lords science and technology committee into the safety of nanotechnology in food, which found that although there is no evidence that the tiny particles are harmful, there are ‘large gaps’ on our knowledge.

The committee called for the Food Standards-Agency to compile a database of nanoproducts that can be accessed by the public. The FSA is not in favour of nanoparticles being declared on food labels, saying they are cluttered enough already.

This is accurate reporting – still on a roll here.

The inquiry also criticised the food industry for being unnecessarily ‘ secretive’ about the products it has in the pipeline. It said this seemed mainly to be because it was concerned about the public’s reaction.

Julian Hunt of the Food and Drink Federation said: ‘Given that nanotechnology is in its infancy in the food and drink sector, and that bringing innovations to market is a long and complex process, we are surprised that the report seems to criticize the food industry for an apparent reluctance to communicate extensively on this subject.

‘There are many questions and unknowns about the potential future uses of nanotechnologies in our sector, and there is much work still to be done by scientists, governments and regulators, as well as the food and drink industry.’

And we finish with the report’s critique of the food industry – which was the main thrust of the associated press release – and a response from an industry representative.

And at the end of the piece, I have to say that it is largely accurate and informative – emotive maybe, but not seriously misleading.  I would actually go further and say that, once the in-your-face headline and opening sentences have pulled readers in, they might actually learn something!

Of course, the fear is that readers will miss the nuances and not read past the headline and, as a result, get completely the wrong end of the stick.  I wonder how likely this is in this case though. Do people really believe in “grey goo” or is the joke on over-sensitive scientists here?

There are obviously major issues surrounding science reporting in the Tabloids, and I don’t for one minute want to give the impression that I am supporting dangerously misleading and disingenuous reporting.  But in this instance, there’s little of substance to complain about once you get beyond the occasionally jarring language.  And it might actually lead to some readers having a better grasp of what nanotech has to do with food… possibly!

Go Fiona!

Since when did peer review journals start to put press hits before published data?

Scientific peer review journals are a cornerstone of modern science – providing an authoritative repository of scientific discovery that researchers and others can examine, test and build upon.  Publication in peer review journals is the primary route by which new science is made available to people, and the “gold standard” against which science coverage in the media is evaluated.

Yet over the past couple of months, I’ve come across two cases where journals were more interested in publicity than publication – releasing information to the media and the public on forthcoming publications before the papers were generally available.  The result is media coverage that cannot be validated against the original research, and a dangerous shift in authority from scientists to journalists and press officers…

This cannot be good for balanced science reporting!

Back in August, the European Respiratory Journal sent out an embargoed press release on a potentially high profile paper associating nanoparticle exposure to seven cases of severe lung disease and two deaths in China.  When the embargo was lifted, the study was covered in the media (including a suite of articles on 2020 Science) – but the paper remained unpublished.

Concerned that this story was being driven by the journal’s press office and journalists, with readers and researchers having no way to check the facts and assess the study for themselves, I contacted the press office.  This is what I said in an email to them:

…I have written about the paper on my blog at http://2020science.org, and have been concerned that the link to the paper is still not live. As well as putting me (and journalists who have also linked to the paper) in an awkward position, it prevents the scientific community from evaluating the paper for themselves.

I will be posting a blog on this apparent disconnect on my blog very shortly. But before I do, I wanted to check whether the ERJ will in fact be posting the paper on-line asap. I also wanted to provide you with the chance to comment on the time delay between the press release and posting the article, before I say something in public.

Unfortunately, I was specifically asked not to quote the reply I got back from the journal.  However, the gist of it was that journalists could access the paper, and the journal would respond more directly to my question… when they had time.

(And believe me, I fully appreciate the irony of not providing the original reply here in a post about not having access to source information!).

The good news in this case is that the journal did respond to my emails and eventually published the paper on-line – but only after pressure had been applied.

Then this morning I received notification of another paper which was preceded by its press release.  Here’s the opening of the Eurekalert press release that was posted by Inderscience Publishers – publishers of the International Journal of Nanotechnology:

Nanotech protection

Current safety equipment may not be adequate for nanoprotection

Writing in a forthcoming issue of the International Journal of Nanotechnology, Canadian engineers suggest that research is needed into the risks associated with the growing field of nanotechnology manufacture so that appropriate protective equipment can be developed urgently.

Followed by

Dolez and colleagues suggest that as this area of manufacturing grows it would be prudent to develop adequate workplace protection sooner, rather than later. Indeed, those workers most likely to be exposed to nanomaterials will be working in cleaning, bagging and formulation activities as well as surface functionalisation of nanoparticles.

This is a potentially important paper – it questions the adequacy of current safety equipment when working with engineered nanomaterials, and concludes that more work is needed to ensure safe workplaces.

But if you want to know what the authors base their conclusions on, you’ll have to wait – unless you are a journalist that is, in which case you can request a pre-publication copy of the paper.

I emailed the journal this morning to find out when the paper will be available to non-journalists (including scientists and interested members of the public).  The answer?

The issue should be published on 1 December 2009.

In other words, the only information most people will have access to on this study for the next six weeks will come from the journal’s press office, and from science writers!

These aren’t isolated cases.  It seems that, in the push to survive the digital revolution, some peer review journals are putting publicity ahead of integrity – encouraging science reporting that cannot be verified against the source, and preventing readers from assessing the validity of the studies they read about.

At a time when the soundness of science coverage in old and new media is already under scrutiny, surely this type of behavior is tantamount to the scientific community shooting itself in the foot!

Not every journal is guilty of playing the publicity card.  But to prevent the bad players from giving science reporting a bad name, perhaps it’s time for a peer review journal code of conduct that establishes principles of responsible behavior.  Amongst those principles, I would suggest a commitment to the integrity of the scientific process, and an agreement not to put out  media “teasers” ahead of publications.

The alternative is the spectacle of a once-respected tradition dissolving into disrespect, while further compromising the already-tenuous authority of science reporting.

And this cannot be good for science, or the society it aims to serve.

Postscript

I should be clear that I have no beef with embargoed press releases that are sent out ahead of a publication – as long as the respective paper is made generally available at the same time as the embargo is lifted.  This approach – used by some journals – gives journalists the opportunity to digest new research and write informed pieces, without the pressure of being scooped by less thorough colleagues. And in many cases it strengthens the integrity of science reporting.  What is unconscionable in my opinion though is issuing a statement or lifting a press release embargo without publishing the original study.  This can surely only be a cynical move to increase publicity for the journal, rather than disseminating the science.

There are some things they don’t cover in media training, like giving interviews while suffering from stomach flu, talking to reporters thousands of miles away while on a dodgy cell phone connection, or speaking intelligently while your three-year-old niece runs rings around your legs.  It’s probably because they come under the “so bloody stupid no one would ever think to advise you not to do these things” category.  Yet sometimes we find ourselves in these uncharted waters.  Which is why Tom Mackenzie’s otherwise strong piece in today’s Guardian on nanotechnology in China ended up with less than perfect input from yours truly!

Rather than rant about the injustices perpetrated by scientific illiterates and the opportunistic press though, I’m breaking with tradition today and admitting that the fault probably lies with me…

Mackenzie’s piece addresses the rise of China as a major international player in the emerging field of nanotechnology.  It’s an important piece, and one that needs to be taken seriously. Given China’s recent track record on product safety, it rightly balances coverage of technical and commercial advances with concerns over possible health issues.  But here’s where things get a little skewed.  Tom writes:

Underlying these developments are serious safety concerns. Nanoparticles are so small they are easily inhaled and absorbed through the skin. Dr Andrew Maynard, the chief science advisor to the Project on Emerging Nanotechnologies at the Woodrow Wilson International Center for Scholars in Washington, says that some nanoparticles could be deadly. “Nothing has yet been confirmed, but there are strong suggestions that inhaling these particles could cause lung cancer or lung disease,” he says. “If carbon nanotubes behave anything like asbestos, we won’t know what the health impacts are for about 20 years, because that’s how long it can take from exposure to the onset of the disease.”

Flagging up these concerns is essential—nanotechnology is leading to novel materials that could well cause harm in novel ways, unless we work out ahead of time how to use them safely.  But the paragraph is a tad on the misleading side.  Nanoparticles are NOT easily absorbed through the skin (the skin is actually pretty good at keeping them out of the body).  And to say that some nanoparticles could be deadly confuses an already complex issue.  Yes, there are serious concerns over materials like long thin multi-walled carbon nanotubes. But plenty of nanoparticles are likely to be no more harmful than their non-nanoscale counterparts.

The issue here though is that I was Tom’s source on nanotechnology safety, and I screwed it up—I wasn’t sufficiently clear or focused to provide him with the information he needed to place the story in a sound, science-based context.

I’m not beating myself up over this (too much).  It happens, and in many cases less-than-perfect science coverage in the media gets absorbed into the bigger story and evens out over time—the biggest impacts being dented pride and the derision of one’s colleagues.

But that’s no excuse for sloppy communication. Poor science in the media muddies issues, and at worst can lead to misinformed and potentially damaging decisions being made. Yet an absence of science coverage leaves us in an even worse position.  Which means that scientists need to know how the media works, and their role in ensuring stories are founded on science reality rather than speculation.

So, mea culpa in this instance. At the end of the day, the better we as scientists communicate to—and through—journalists, the better equipped people will be to make informed judgments.

As they say, “practice makes perfect.” Next question, please?
