Aptamers and Maria DeRosa

Today’s (Oct. 25, 2011) next interview is with Maria DeRosa of the DeRosa Lab at Carleton University (Ottawa, Canada) where she and her colleagues work on bionanotechnology projects. (The Highlighting the 2011 Dance Your Ph.D. contest posting featured a Ph.D student from her lab who is one of this year’s contest finalists.)

Before proceeding to the interview, here’s a little bit about the DeRosa Lab (from the website homepage),

The first step in the rational design of novel bionanotechnology is to find the right molecular components for the task. Our group seeks to investigate the use of chemically-modified nucleic acid aptamers, single stranded DNA or RNA sequences that specifically bind to a diverse variety of targets, in biosensing and catalysis.

Here’s some information about Dr. DeRosa,

Dr. Maria DeRosa’s research examines a type of nucleic acid called ‘aptamers’ that can fold into 3D nanoscale shapes capable of binding tightly to a specific molecular target.  Her group is focused on developing a better understanding of how these systems and using this information to design useful nanotechnology, like biosensors or “smart” delivery devices.  Dr. DeRosa received her Ph.D in Chemistry from Carleton University in 2003 and was presented with a University Senate Medal. She was awarded an NSERC Postdoctoral Fellowship to do research at the California Institute of Technology from 2004-2005 with Prof. Jackie Barton, a world-leader in DNA sensor research. In 2005, she returned to Carleton as a faculty member in the Chemistry Department. Her research group has received funding from the Natural Sciences and Engineering Research Council (NSERC), the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA), the Canada Foundation for Innovation (CFI) and Alberta Innovates Biosolutions.  DeRosa was a recipient of the John Charles Polanyi Research Award for new researchers in 2006 and an Ontario Early Researcher Award in 2010.

Here’s the interview,

*   Are you one of those people who always wanted to be a scientist or was this something you discovered later?

I was never one of those people who knew what they wanted to do from an early age.  I thought about being a doctor, pharmacist, plumber, engineer, bank teller…  In high school, I had many great math and science teachers that inspired me to go into science when I started at Carleton University.  Then, in my third year I got a summer job working in Dr. Bob Crutchley’s research lab.  He was a great mentor and it was then that I started seriously thinking about a career as a scientist.  I loved the idea of research, that I was working on a problem and no one knew what the answer would be.  I wanted the answers!

*   How did you get interested in aptamers (and could you briefly describe what they are)?

Aptamers are synthetic pieces of DNA that can recognize and stick to a molecular target.  The targets can vary from things that are very small, like a drug molecule to something much larger, like bacteria or viruses.  Because they can recognize and stick to other molecules, people are interested in using them as receptors for sensors.  I had never even heard of them until about 2005.

After my Ph.D., I went to Caltech to do something called a postdoctoral fellowship.  It was a research position in the lab of Dr. Jackie Barton, one of the world’s top DNA researchers (she just won a National Medal of Science a couple days ago).  She wasn’t working with aptamers but she opened me up to the idea of using DNA in an “unnatural” way.  Most of us, when we are thinking of DNA, we think of our genes and that it is the blueprint for life.  But from a chemistry point of view, DNA is just another material that has certain chemical properties that can be useful for other applications.  In Jackie’s lab, I learned how to make synthetic DNA and I started reading about aptamers.  I found the whole field fascinating and I knew that I wanted to be a part of it.

*   What applications are there for your work? (I noticed that you discussed fertilizers in your TEDxCarleton talk. Is agriculture an area of particular interest?)

Applications for aptamers mostly stem from their ability to bind tightly and selectively to other molecules.  So, they are typically used in technology such as biosensors where they can serve to detect low levels of something, like a toxin or a virus for example, in another matrix.  We’re developing aptamers for the detection of mycotoxins (toxins that come from moulds) in crops and food.  We’re also working on aptamers for norovirus (the virus that causes Norwalk, that awful stomach bug) so that we can catch it if it is in meat and other foods before they get sent off to stores.

We are also trying to use aptamers for triggered delivery of drugs and/or nutrients.  In many cases with drugs, we want them to act on certain cells or tissues and not on others.  So, we need to be able to control where the drug is released in the body.  There is a similar problem in agriculture.  We want to give crops certain nutrients from fertilizers but if we deliver them at the wrong time, they will be washed away and not taken up by the crop.  This leads to major economic losses for the farmer and problems for the environment.  With our work, the idea is that we use the aptamer to control the release of whatever we are delivering.  We incorporate the aptamer into a coating that covers the drug or nutrient.  The aptamer is there to recognize a stimulus that we want to use to release the contents.  For drug delivery, that stimulus might be a cancer cell or a disease biomarker.  For fertilizers, that stimulus might a be a plant signal that corresponds to the plant’s need for nutrients.  (We are working with Dr.Carlos Monreal from Agriculture and Agrifood Canada on the fertilizer project, and he is an expert in these plant signals and ‘smart fertilizers’.)  In the absence of that signal, the coating does not allow the release of the drug or nutrient.  But, once the aptamer recognizes that key signal, the aptamer distorts or destroys the coating and it allows the nutrient to be released.

*   According to the information on your lab website, you are the recipient of Canada Foundation for Innovation (CFI) Leaders Opportunity Fund (LOF) monies. Are these funds being applied to a particular project in your lab or are they used to support your general area of research?

CFI funds helped us to build our facility called the LADDER (Laboratory for Aptamer Discovery and Development of Emerging Research applications).  That funding allowed us to get the state-of-the-art equipment we need to support all of our research projects.  Without CFI funding, our work would not be possible!

*   Given your TEDxCarleton talk and your involvement in the 2011 Canadian Science Writers conference (researchers’ speed dating [I couldn’t confirm it but I’m pretty sure I saw your name listed for this event]), I gather you’re quite interested in public outreach. Why do you think it’s important?

Yes, I was at that ‘speed dating’ event and I am very committed to science outreach.  The public helps to support my research through funding like NSERC and CFI, so I think it is critical that I can explain to them what it is that I do, why it is important, and why their money is well-spent.  The general public may not know what an aptamer is, but they all realize the importance of keeping our food free of toxins or the need to make drugs that are better able to target disease.

*   I noticed that one of your students is a finalist in the Dance your Ph.D 2011 contest. And it’s not the first time. Do you find a lot of scientists with ‘dance’ tendencies are attracted to your lab? Are you one of those scientists?

My students won the competition last year and then they were finalists again this year!  I’m not sure if dancers are attracted to my lab or if my students are just as committed to outreach as I am!  My students are very excited to talk about their research with anyone who will listen.  This contest is a fun way to explain their work to everyday people.  Friends and family, after watching these dances online, have told me that they finally understand what is going on in my lab.  Maybe I should dance more!  (I’m not a dancer and you will not find me in either video…I support them from the sidelines!)

*   Is there anything you would like to add?

Thanks for profiling me and it has been fun!

Maria, thank you for this intriguing peek into your research, the field of DNA nanotechnology, and your (and shared by your students) commitment to public science outreach. I’m very happy you managed to cram the time to answer these questions into your schedule.

Reaching out with big science panel at the 2011 Canadian Science Policy Conference

Today’s 2011 Canadian Science Policy Conference (CSPC) interview is with Dr. Tim Meyer, Head of Strategic Planning & Communication for TRIUMF who will be one of the presenters on the Reaching out with big science panel. Here’s a little more about Tim (from Tim Meyer’s profile page on the TRIUMF website),

Dr. Timothy Meyer came to TRIUMF from the U.S. National Academies in Washington, D.C.. At the National Academies, Meyer was a senior program officer at the Board on Physics and Astronomy. He received a Notable Achievement Award from the [US] NRC’s Division on Engineering and Physical Sciences in 2003 and a Distinguished Service Award from the National Academies in 2004. Meyer joined the NRC staff in 2002 after earning his Ph.D. in experimental particle physics from Stanford University. His doctoral thesis concerned the time evolution of the B meson in the BaBar experiment at the Stanford Linear Accelerator Center. His work also focused on radiation monitoring and protection of silicon-based particle detectors. He is a member of the Canadian Association of Physicists, Canadian Science Writers Association, American Physical Society, American Association for the Advancement of Science, Materials Research Society, and Phi Beta Kappa.

Here’s a little more on the Reaching out with big science panel. From the CSPC agenda page,

The public often learns of developments in science in the media distilled from press offices at peer-reviewed journals or universities. In a few cases, research institutions such as the Mayo Clinic and CERN have also developed a reputation for being seen as authoritative sources of science news and information for the public. In recent years, the Canadian research landscape has grown to feature a number of ‘big science’ facilities. These institutions, such as TRIUMF, Ocean Networks Canada, the Canadian Light Source, SNOLab and the Perimeter Institute, conduct research at the forefront of science – often at the convergence of science disciplines and with a scope and scale that is larger than traditional research institutions in government or the academy. In addition to research, all of these laboratories also engage in a number of forms of public engagement and outreach, ranging from media relations to classroom education. In a media landscape where science reporting is becoming increasingly fractured, what role do Canada’s big science facilities have in being sources of science news, information and education?

Here is the interview that Tim kindly gave during a period when he has been traveling extensively on behalf of TRIUMF,

  • For those who are not familiar with TRIUMF could you please give a brief description of it and an explanation of how it fits into the Canadian science landscape?

TRIUMF IS CANADA’S NATIONAL LABORATORY FOR PARTICLE AND NUCLEAR PHYSICS.  IT IS OWNED AND OPERATED BY A CONSORTIUM OF 17 CANADIAN UNIVERSITIES FROM COAST TO COAST.  TRIUMF WAS FORMED MORE THAN 40 YEARS AGO TO POOL RESOURCES AND TALENTS FOR RESEARCH INFRASTRUCTURE THAT WAS TOO COMPLEX AND EXPENSIVE TO MAINTAIN BY A SINGLE UNIVERSITY.

THE TRIUMF TEAM INCLUDES ABOUT 350 STAFF ON 12 ACRES IN VANCOUVER ON THE SOUTH SIDE OF THE UBC CAMPUS. TRIUMF OPERATES 5 DIFFERENT ACCELERATORS INCLUDING THE WORLD’S LARGEST CYCLOTRON.

TRIUMF IS UNIQUE IN CANADA AND ONE OF THE TOP THREE LABORATORIES IN THE WORLD FOR CAPABILITIES TO RESEARCH AND DEVELOP ISOTOPES FOR SCIENCE AND MEDICINE.

TRIUMF IS ONE MEMBER OF A FAMILY OF NATIONAL LABORATORIES IN CANADA INCLUDING THE CANADIAN LIGHT SOURCE [represented on the panel], SNOLAB, PERIMETER INSTITUTE [represented on the panel], AND THE CANADIAN NEUTRON BEAM CENTRE.

  • I’ve read the description for this panel and wonder how this fits into a science policy conference. Is there going to be some link made between public engagement and public policy?

ABSOLUTELY. THIS PANEL SESSION SHOWS UP FOR TWO REASONS.  FIRST, PUBLIC ENGAGEMENT IS PART OF THE OBLIGATION OF PUBLICY-FUNDED RESEARCH ACTIVITIES.  EITHER TO SHARE THE BENEFITS OF THE RESEARCH OR SHARE THE INSPIRATION THAT COMES FROM DISCOVERY… OR ANY OTHER NUMBER OF REASONS.  SO IN THE CONTEXT OF SCIENCE POLICY, THIS PANEL WILL DISCUSS HOW THE PUBLIC ENGAGEMENT AND “SHARING” FROM LARGE SCIENCE FACILITIES MIGHT DIFFER FROM THAT OF INIDIVUAL RESEARCHERS—OR EVEN WHETHER LARGE SCIENCE FACILITIES HAVE A LARGER OBLIGATION.

SECOND, LARGE SCIENCE FACILITIES PRESENT A CHALLENGE FOR TRADITIONAL SCIENCE POLICY BECAUSE THEY REPRESENT LARGE UP-FRONT CAPITAL COMMITMENTS WITH SIGNIFICANT ONGOING OPERATING COSTS.  WHAT IS THE RESPONSIBLE APPROACH FOR MANAGING A PORTFOLIO OF THESE LABORATORIES?  IN THIS PANEL DISCUSSION, WE WILL BE LOOKING AT THE SOME OF UNIQUE FEATURES OF NATIONAL SCIENCE FACILITIES THAT MAKE THEM INVALUABLE AS WELL AS OUTLINE SOME ROUTES FOR IMPROVING THEIR STEWARDSHIP.  SO THIS PANEL DISCUSSION WILL ENGAGE THE ENGAGERS IN AN ENGAGING CONVERSATION!

  • Could you briefly discuss some of the public outreach and engagement initiatives taken by TRIUMF?

TRIUMF’S STRATEGIC PLANNING AND COMMUNICATIONS OFFICE (SPCO) OVERSEES PUBLIC RELATIONS, CONFERENCE SERVICES, PUBLICATIONS, AND EDUCATION AND OUTREACH ACTIVITIES AT THE LAB.  FOR INSTANCE, TRIUMF CO-SPONSORS A MONTHLY LECTURE SERIES FOR HIGH-SCHOOL STUDENTS ON BREAKING-NEWS TOPICS IN PHYSICS FOR PEOPLE IN THE VANCOUVER METRO AREA.  TRIUMF ALSO SELECTS 2-3 OF THE TOP BC AREA HIGH SCHOOL STUDENTS AND WARDS THEM A SUMMER RESEARCH FELLOWSHIP AT THE LAB ALONGSIDE THE WORLD’S BEST SCIENTISTS.  TRIUMF ACTIVELY PARTICIPATES IN CONVERSATIONS TO ENGAGE THE PUBLIC ABOUT THE NATURE AND IMPORTANCE OF SCIENCE.  DURING THE FIRST MONTH AFTER THE FUKUSHIMA CRISIS, TRIUMF PROVIDED INVALUABLE COUNSEL TO GOVERNMENT AGENCIES AND THE MEDIA ABOUT WHAT WAS ACTUALLY GOING ON.  ELSEWHERE, TRIUMF HAS PROVIDED EXPERTS TO SCREENINGS OF SCIENCE-RELATED FILMS PART OF THE VANCOUVER INTERNATIONAL FILM FESTIVAL.  WE ALSO USE TWITTER TO CALL ATTENTION TO IMPORTANT SCIENCE DEVELOPMENTS AND WE ARE DEVELOPING A LIBRARY OF ENTERTAINING “BEHIND THE SCENES” VIDEOS ON OUR YOUTUBE CHANNEL ABOUT RESEARCH AT TRIUMF.  TRIUMF HAS BEEN AN OPINION AND TECHNOLOGY LEADER IN CANADA’S DISCUSSION ABOUT THE MEDICAL-ISOTOPE CRISIS, ANOTHER EXAMPLE OF PUBLIC ENGAGEMENT ON POLICY TOPICS SHAPED BY SCIENCE AND TECHNOLOGY.

  • I’m surprised by the failure to include social media as part of the new science communications landscape. Do you have any thoughts on that exclusion?

WHAT MAKES YOU THINK IT’S NOT INCLUDED? YOU HAVEN’T SEEN THE TALKS YET!  JUST TEASING.  WE WILL ALL CERTAINLY BE TALKING ABOUT SOCIAL MEDIA AND WE’LL EVEN BE TWEETING AND BLOGGING LIVE FROM THE CONFERENCE.

  • Can you offer a preview of what you, in particular, will be discussing during the panel session?

WELL, I DON’T SPOIL EVERYTHING, BUT HERE’S WHAT I CAN SAY IN ADVANCE.  I WILL BE TALKING ABOUT THE SET OF MOTIVATIONS FOR PUBLIC ENGAGEMENT FOR RESEARCH LABORATORIES.  NATIONAL SCIENCE FACILITIES ARE NOT THE BE-ALL, END-ALL FOR RESEARCH AND SCIENCE COMMUNICATION, BUT THEY PLAY A CLEAR, UNMISTAKABLE ROLE THAT IS INCREASINGLY IMPORTANT. I WILL DISTINGUISH THE RESPONSIBILITIES OF A NATIONAL SCIENCE FACILITY FROM THOSE OF INDIVIDUAL RESEARCH EFFORTS.  I WILL ALSO DISCUSS HOW THE PUBLIC ROLE OF A LABORATORY IS EVOLVING IN THE INTERNATIONAL CONTEXT AS WELL AS THE VERY-MUCH-IN-DEMAND CONTEXT OF INNOVATION AND COMMERCIALIZATION.

  • Is there anything you would like to add?

(1) MANY FEEL THAT PUBLIC OUTREACH AND EDUCATION IS JUST A SELF-SERVING TRICK OF SCIENTISTS—IF MORE PEOPLE KNOW ABOUT SCIENCE, THEY’LL LIKE IT, AND THEN WANT TO SPEND MORE TAX DOLLARS ON IT.  THIS SIMPLISTIC LOGIC HAS ACTUALLY BEEN SHOWN TO BE FALSE.  THERE IS NO PROSELYTIZING GOING ON.  WE’RE NOT HERE TO MAKE YOU LIKE SCIENCE SO YOU LIKE US!  WHAT THIS IS ABOUT IS GIVING BACK TO KEY ELEMENTS OF THE PUBLIC AND ABOUT ADVANCING SOCIETY.

(2) THE CANADIAN SCIENCE POLICY CONFERNECE IS AN IMPORTANT STEP FORWARD FOR CANADA.  IT AIMS TO PROVIDE A FORUM FOR KEY ISSUES TO BE DISCUSSED AND EXAMINED.  THE KEY CHALLENGE IS TO DRIVE THE FIELD FORWARD BY RESOLVING SOME OF THESE ISSUES.  BETTER AND BETTER INFORMED HAND-WRINGING ABOUT THE STATE OF SCIENCE OR INNOVATION (I.E., JUST COMPLAINING) IN CANADA IS GOING TO GET OLD.  THE OPPORTUNITY OF THIS CONFERENCE, AND THE INTENTION OF THE ORGANIZERS, IS TO START TO GENERATE A NEW CONVERSATION.  WHAT ARE THE BASELINES EXPECTATIONS FOR SCIENCE?  WHAT RESULTS HAVE WE ACHIEVED WITH OUR RECENT INNOVATIVE PROGRAMS?   WHEN WE LOOK AT THESE QUESTIONS, WE START MOVING THE ENTIRE COUNTRY FORWARD.

Thank you, Tim. I’m very grateful you managed to squeeze this interview into your schedule. I imagine this will be a lively presentation given your comments.

Education and training of scientists panel at the 2011 Canadian Science Policy Conference

On the heels of my last posting which featured Science magazine’s 2011 Dance Your Ph.D. contest, it seems like a good idea to follow up with another science student-themed posting.

Dr. David Kent who will be moderating the Education and training panel at the 2011 Canadian Science Policy Conference (CSPC) being held in Ottawa, Canada from Nov. 16 – 18, 2011 has enthusiastically granted me an interview. (My Oct. 19, 2011 posting featured a description of the 2011 CSPC conference and highlighted some of the events.)

First, here’s a little bit about David (from the 2011 CSPC conference website),

Dr. David Kent is a CIHR [Canadian Institutes of Health Research] postdoctoral fellow at the University of Cambridge, UK. He currently sits on the executive of the Canadian Association of Postdoctoral Scholars and created the website The Black Hole which provides information on and analysis of issues related to science trainees in Canada. Previously, Dr. Kent served as joint coordinator for the UBC branch of the Let’s Talk Science Partnership Program (2004-07), an award winning national science outreach program. Dr. Kent grew up in St. John’s, NL, obtained a B.Sc. in Genetics and English Literature at the University of Western Ontario and completed his Ph.D. in blood stem cell biology at the University of British Columbia. He has been awarded scholarships or fellowships from the CIHR, NSERC, the Canadian Stem Cell Network, the Michael Smith Foundation for Health Research, and the Lady Tata Memorial Trust. His current laboratory research focuses on normal blood stem cells and how changes in their regulation lead to cancers.

Here’s the description of the panel (Education and training of scientists) David will be moderating,

Over the past 15 years, there has been an enormous shift in the human resources performing scientific research. The training period has lengthened significantly and adjustments must be made to address the growing concerns of young scientists. Many individuals, who do not have permanent positions, share a unique set of experiences and challenges that need to be better addressed in order to avoid wasting the substantial resources invested in their education and training.

This panel aims to address two main themes:

  1. Are we producing too many biomedical research trainees?
  2. What careers will the large majority of highly specialized PhDs undertake and who should facilitate these transitions?

Presentations and discussion from Alan Bernstein (Founding Director of CIHR), Angela Crawley (Canadian Association of Postdoctoral Scholars), Suzanne Fortier (President of NSERC), and Olga Stachova (COO, MITACS) will be introduced and moderated by David Kent (University of Cambridge and founder of http://scienceadvocacy.org, aka The Black Hole).

Here’s  the interview,

  • I’m intrigued by the description for this panel which asks a highly specific question (Are there too many biomedical research trainees?) and a much more general question (What careers will the majority of highly specialized PhD undertake and who should facilitate the transition?). Assuming that you proposed the panel, how did you arrive at these two questions in particular?

The first question definitely has its origins in Jeff Sharom’s piece in Hypothesis Journal (http://www.hypothesisjournal.com/pdfs/vol6num1/17.pdf) who queried whether we were producing too many biomedical trainees.  It is also a great way to capture a large issue under a simple title, but by no means would I consider it specific and I think just about anybody you ask would have the answer “it depends…” followed by discussions ranging from the demands of a knowledge-based economy to keeping young people out of the workforce for a few more years.

As for the second question, I see this one having a much more straightforward answer as it is really an attempt to assign responsibility to a sector of society to help deal with the problem – I’d like the panel and delegates to help steer future advocacy efforts to address the fundamental issues.

  • Given that you are currently working as a postdoc at the University of Cambridge, would you be asking these same questions on a UK panel and if not, why not?

The UK is a very different beast, but I think there is still overlap – in particular, the challenges facing those seeking an academic post and those debating whether or not to leave the academy.  The one thing that is very different in the UK – and I’m torn as to whether or not it’s a good thing or a bad thing – is that time-to-degree is substantially shorter with PhD programs lasting 3-4 years.  If you’re equipping people to go off into other careers, this is brilliant because they don’t get stuck in a very long PhD, but rather come out with the nuts and bolts of a PhD training.  However, this sort of system also tends to lead to what I would call “safe” projects that will yield results in the limited time frame and leave little room for exploring risky projects.  We talk about this in an old entry on the Black Hole called “The Rise of the Cookie-cutter PhD” (http://scienceadvocacy.org/Blog/2009/11/17/science-is-like-baking-the-rise-of-the-cookie-cutter-phd/)

  • Will you be acting as a moderator only or will you also speak to the questions? If you do speak to the questions, could you give a preview of your presentation?

I will introduce the panel and in doing so will try to set the stage for the audience – chart the change in demographics, highlight the issue of career stasis in academic labs, etc.  Much of my presentation will draw from entries on the Black Hole such as the Changing Human Resources in AcademiaSay no to the second Postdoc, and Professionals in High Demand.  Briefly, I’ll show statistics on the longer training times and summarize the unrest in academic labs.  In the moderation of the panel discussion, I’ll include some resources on how some universities have started to tackle the issues and some innovative programs that are helping young academics make choices sooner.

  • What do you hope will be the outcome(s) of having this panel at the 2011 CSPC?

For me, the biggest mission is awareness – I want policy makers, granting councils, and industry leaders to recognize the growth in highly trained scientists and the immense number of talented people that often finds themselves “stuck”.  These are people who have trained for nearly a decade and only a fraction of them can end up on the path they have been trained for (unlike doctors, lawyers, accounts)

A complete bonus would be to get some strategies for unsticking these people and some guidance on where to broach the issue.  We’ll see how it goes!

  • Is there anything you would like to add?

The only final thing I would suggest is for young scientists who have any sort of inclination toward or interest in science policy to get out there early – two or three days at a conference like the CSPC can be career changing or it could simply allow you to better understand the machinery that ends up impacting how you will be funded, how your trainees will be trained, and how research gets (or doesn’t get) incorporated into government policy.  Take off the blinders once in a while and try something new.

Thank you for taking the time to provide some insight into your topic and your presentation. I wish you and your panel the best of luck at the conference.

ETA Nov. 9, 2011: For Twitter purposes I decided to call this panel the ‘Kill all your darlings/science grads” panel. “Kill all your darlings” is a phrase I came across that describes what writers sometimes have to do when they edit a piece and must cut a wonderful sentence or phrase because it doesn’t fit. I gather that there is a problem (not only in Canada) with fitting science grads into the larger science enterprise.

Dr. Andrew Maynard discusses the Health Canada nanomaterial definition

I have often referred to and linked to Andrew Maynard’s writing on nanotechnology issues and am pleased to note he has kindly answered some questions about the Health Canada Working Definition of Nanomaterial. Before launching into his responses, here’s a little more about him.

Dr. Andrew Maynard was originally trained as a physicist and graduated with a PhD from Cambridge, UK  in 1993. He worked for a number of years for the UK Health and Safety Executive moving to the US to work with the National Institute of Occupational Health and Safety where he helped set up a nanotechnology safety programme post 2000 when the NNI was established. By 2005, he was employed at the Project on Emerging Nanotechnologies as their Chief Science Advisor. As of April 2010, he assumed responsibility as director of the Risk Science Center at the University of Michigan School of Public Health. He consults internationally on nanotechnology safety issues. He was a member of the expert panel consulted for the nanotechnology report, Small is Different; A Science Perspective on the Regulatory Challenges of Nanotechnology, published by the Council of Canadian Academies in 2008.

Since the 2008 report for the Council of Canadian Academies, Andrew has adopted a different approach to regulating nanotechnology, a change I first noted in an April 15, 2011 posting on the University of Michigan Risk Science Center blog. Excerpted from that posting,

Engineered nanomaterials present regulators with a conundrum – there is a gut feeling that these materials present a new regulatory challenge, yet the nature and resolution of this challenge remains elusive.  But as the debate over the regulation of nanomaterials continues, there are worrying signs that discussions are being driven less by the science of how these materials might cause harm, and more by the politics of confusion and uncertainty.

The genesis of the current dilemma is entirely understandable. Engineered nanomaterials are typically the product of nanotechnology – a technology that has been lauded as leading to designed materials with unique physical and chemical properties.   Intuitively it makes sense that these unique properties could lead to unique risks.  And indeed a rapidly growing body of research is indicating that many nanoscale materials behave differently to their non-nanoscale counterparts in biological environments. Logically, it seems to follow that engineered nanomaterials potentially present risks that depend on their scale, and should be regulated appropriately.

Yet the more we learn about how materials interact with biology, the less clear it becomes where the boundaries of this class of materials called “nanomaterials” lie, or even whether this is a legitimate class of material at all from a regulatory perspective.

I waffle somewhat largely due to my respect for Andrew and his work and due to my belief that one needs to entertain new approaches for the emerging technologies, even when they make your brain hurt. (Before proceeding with Andrew’s comments and for anyone who’s interested in my take here is, My thoughts on the Health Canada nanomaterial definition.)

In any event, here are Andrew’s responses to my questions,

  • I have warm feelings towards this definition, especially the elaboration where I think they avoided the problem of including naturally occuring nanoparticles (as per your comment about micelles in milk); and they specify a size range without being doctrinaire about it. How do you feel about it, given that you’re not in favour of definitions?

The problem is that, while the Health Canada is a valiant attempt to craft a definition based on the current state of science, it is still based on a premise – that size within a well defined range is a robust indicator of novel risk – that is questionable.  Granted, they try to compensate for the limitations of this premise, but the result still smacks of trying to shoehorn the science into an assumption of what is important.

  • Do you see any pitfalls?

A large part of the problem here is an attempt to oversimplify a complex problem, without having a clear understanding of what the problem is in the first place.  Much of my current thinking – including questioning current approaches to developing definitions – revolves round trying to work out what the problem is before developing the solution.  But this makes commenting on the adequacy or inadequacy of definitions tricky, to say the least.

  • Is there anything you’d like to add?

My sincere apologies, I’ve just got to 5:00 PM on Sunday [Oct. 23, 2011] after working flat out all weekend, and am not sure I have the wherewithal to tackle this before collapsing in a heap.

I am hugely thankful that Dr. Maynard extended himself to answer my questions about the Health Canada definition of nanomaterial. To Andrew: a virtual bouquet of thanks made up of the most stunning flowers and scents you can imagine.

Interview with the Urbee car’s Jim Kor

In an earlier posting today, (Manitoba’s Urbee) about the Urbee, I promised an interview with Jim Kor, project leader and lead designer. Befoe getting to the interview, here’s a little biographical information from the Urbee website’s Team page,

Jim Kor is a professional engineer (mechanical) with over 35 years of experience in designing automotive, bus, rail, agricultural, and heavy mobile equipment as well as civil structures and product for the aerospace and medical industries. He is the senior designer and project leader for the Urbee project. Jim is the owner of Kor Product Design, a 30 year old international consulting firm.

Congratulations on your achievement, i.e., getting your first prototype completed. Could you describe the 3D printing process in simple terms? (e.g. do you lay down layers of atoms? particles? bits of polymer?; what does a 3D printer look like compared to the printers most of us are accustomed to?; etc.)

The 3-D printing process is an additive process, where a ‘3-D printer’ precisely places a material (such as plastic), thin strands or particles at a time, layer by layer, with each layer bonding to the next, all under computer control, until a rigid part emerges. These 3-D printers look like large metal boxes, and can be the size of bar-fridges (desktop models) or walk-in freezers (floor-mounted models). The input to the machine is strands of material (wound in loops, like wire), and the output is finished parts.

Has this 3D printing process been enabled by nanotechnology?

Yes, I believe so. The head, where the material emerges hot and bonds to the lower layer, is where all the action takes place, and most of the technology is focussed.

Is every single element (tires, windows, seats, panels, etcl) of this car produced by 3D printing?

On our first prototype Urbee, just the body panels are 3-D printed. All the windows were also 3-D printed, but these 3-D printed parts were used as patterns for making the plastic and glass windows within Urbee.

How long does it take to print a piece?
The larger pieces currently can take a long time, or at least they did on our first prototype. But, we are learning, and this machine time will come down, especially with further progress regarding the printing of larger panels.

I gather you’re raising funds for your 2nd prototype. Is that one going to be identical to the first or are you refining the design and how?

The second prototype will greatly benefit from the first prototype (the first time we have seen all major components working within the car). We plan on refining and expanding our use of 3-D printing, taking it into the interior and parts of the chassis.
How close is your product to being commercialized and what would it take to get it commercialized?

We are at first prototype stage. Most optimistic production date would be 2014. It will take continued Research & Development by our Team to get us there.

Could you tell me a little bit about how this project came to be located in Manitoba?

The originators of the project, and most of the Urbee Team lives and works (as designers and engineers) in Winnipeg, Manitoba, Canada.

Have you gotten provincial and federal support for this project? And, if any, what kind? Have you also gotten support from venture capitalists, banks, etc.?

We have gratefully received financial assistance, but the project remains largely self-funded. Without financial assistance (especially donations), and without the expertise and in-kind support of our sponsors (as listed on our website), the project could not have advanced to the point it has. We continue to receive fantastic support from some of the best people, within some of the best companies and organizations in the world. Hats off to them for making this project what it is today.

On a completely different note, Urbee sounds like Herbie, the name of a Volkswagen beetle featured in a number of Disney movies. Was this intentional?

No, it was not intentional. URBEE stands for URBan Electric with Ethanol as back-up. It is a project name that has stuck, is rather unique (easy to do google searches), and which I personally have grown to like. I don’t mind being associated with the original VW Beetle, one of the best-selling cars in the world, … ever, …. (over 24 million units sold worldwide, I believe).

Why did you choose that particular colour for your prototype?

The Industrial Designers within the Team chose the colour. They are extremely talented (the best in the world, in my opinion). They have designed the body to not only look aesthetically pleasing and ‘correct’, but have achieved a Coefficient of Drag (Cd) of 0.15, … extremely low for a practical car. Some would say impossibly low, but two independent computer aerodynamic simulations have verified this number, so we are satisfied that we are there. It is what makes us claim that ‘One day all cars will look like this’, because this body shape honours the physics of the problem (a car body moving at the bottom of an ocean of air).

Is there anything you’d like to add?

Yes. Thanks to all those that have helped advance this groundbreaking and important project. Thanks for your interest in this project, that is helping propel it forward. And keep your eye on our website (www.urbee.net), to see where we’re going next.

Thank you and I wish you and your team the best of luck, Jim Kor.

Here’s one more look at the Urbee,

A big thanks to Tim Harper for both his insight and for taking the time to answer questions I had about the report, Report on Global Nanotechnology Funding and Impact (Global Funding of Nanotechnologies and Its Impact) released earlier this week on July 13, 2011.

(a) First, could you tell me a little bit about you and about Cientifica?

My background is hardcore nanotechnology – I spend years building and installing surface science instrumentation for VG Instruments, one of the first companies to commercialise the Scanning Tunnelling Microscope, or at least we did our best. But that was back in the days when a PDP 1-11 was the data system and successfully acquiring an image and interpreting it usually required a trip to Zurich to see Gerd Binnig and Heini Röhring [Note: They won the Nobel prize for their efforts on scanning tunnelling microscope]. I also spent a lot of time on Secondary Ion Mass Spectrometry – hitting surfaces with beams of ions and then collecting what we knocked off.  After that I ran the electron microscopy section at the European Space Agency’s (ESA) labs in Holland before buying a lot of focussed ion beam systems and atomic force microscopes so that we could take things apart atom by atom if we suspected that they may fail half way to Mars!

Cientifica started off as a spin out in 1996 doing contract research for ESA before moving into networking scientists, advising venture capital firms about technology and producing information about nanotechnologies. Over the past ten years our work has been used by most governments, and we have been instrumental in designing or advising on a large number of national nanotechnology projects. After tracking nanotechnology for 12 years and usually being more or less right (blush) we have an increasing number of people who use us as a sanity check for projects and investments. But often the biggest successes are the least visible such as advising a client not to put a few hundred million dollars into manufacturing carbon nanotubes for which there was no channel to market.

(b) Is your latest report, 2011 Global Funding of Nanotechnologies and Its Impact, a successor of sorts (industrial sectors rather than countries are prominently listed) to your 2008 Nanotechnology Opportunities report?

It’s a progression from our first edition of the Nanotechnology Opportunity Report in 2002. In those days people just wanted to know what nanotechnology was, and to cut through a lot of the hype and disinformation. In 2002, 99.9% of people thought that nanotechnology was all about tiny robots. Ten years later it’s probably 90%, but at least the 10% involved in science policy, whether in government or companies know what nanotech really is. What people want now is some usable information  –  how does it affect my business or industry, and how can I take advantage of it. Most of our work is for private clients, who range from start ups through to multinationals and governments, and who tap our expertise in predicting the future impact of technology.

We still do a huge amount of work in industrials sectors, and we have publications in medicine and energy in the pipeline which we hope will allow people to cut through the hype and understand what (and when) the market opportunity will really be.

(c) Why did you choose to focus on nano R&D spending and potential economic impacts? Is it something to do with all of the talk about innovation?

We wanted to look first at the funding in both dollar and purchasing power parity terms as one R&D dollar gets more in China that it does in the US. There is a lot of national pride at stake about who is spending the most, and if you look at per capita spending it gets even more interesting. But getting technology to market isn’t just about making huge amounts of government money available. 90-95% of science funding doesn’t generate anything of any economic use (although it can be very useful for furthering scientific knowledge) so we need to look at how that 5-10% gets to market.  I have had a close relationship with the World Economic Forum for many years which also helps us move away from merely looking at science funding to looking at its economic impact, and we also use a lot of data from the World Bank, OECD [Organisation for Economic Development and Cooperation], and various government studies when we try to model technology diffusion.

Over the years we have developed a quite sophisticated model that allows us to translate these various inputs into fairly good, and quite specific, market predictions. In the past 12 years some people have described our market forecasts as cynical or ultra conservative, but if you look back at what we’ve said and what actually happened, I think you’ll find that we were just being realistic. I know that some people want to see big numbers, but it must be all those years as a scientist that makes me satisfied with accurate numbers, no matter what the magnitude!

Innovation isn’t a problem, the academic system is stuffed to the gills with bright and innovative people, but convincing the rest of the world that they need your innovation is the stumbling block. When we looked at the ability of countries to take advantage of their technology funding, countries such as the US and Germany scored highly as they have plenty of commercial-facing research, a strong tradition of industry-academic partnerships, good government support for technology (and whatever individual academics may say it could be far far worse) and domestic industry hungry for technology to maintain their competitive advantage. What surprised us was the low ranking of the UK. While possessing some of the best universities in the world, the UK economy is predominantly service-based, and real estate and coffee shops tend to be less enthusiastic consumers of nanotechnology than chemical companies and auto manufacturers.

(d) It seems most countries are concerned/worried about the levels of their nano science research, their innovation, and consequent economic prospects. Is there any country that seems confident about its nano economic prospects and why do you think that is?

That is partly true, but most governments do not have a joined up strategy which can cause significant structural problems in the future. Post financial crisis, the emphasis has shifted to trimming budgets rather than making long term strategic investments, which is what nanotechnology is, and this gives us two major problems.

Firstly, there just isn’t enough support for early stage spin outs. There is a financial desert to cross between being a full time academic and having a company with enough proof of concept to attract angel or VC [venture capital] funding. Unless governments address this aspect it really doesn’t matter how much innovation is produced by the academic sector, most of it will go nowhere (other than the parts cherry picked by large companies). We really need to start thinking about the path that innovation takes to market, and to make that as smooth as possible.

Secondly, and more seriously, we are approaching a dangerous time in human history. Science and technology are moving faster than ever before thanks to the automation of lab systems and almost real time sharing of results through online journals. At the same time, people are increasingly distrustful of technology, perhaps as a result of it being so far removed from everyday life, which leads to whole areas of science such as GMOs [genetically modified organisms] or nuclear energy becoming tainted. So while we have increasing pressure on food, water, energy, health and every other resource caused by a rising global population, we are being denied the tools which could help improve the conditions of people across the globe. I’m deeply involved in an initiative that sprung from our emerging technologies work at the World Economic Forum, which involves the setting up of a global Centre for Emerging Technologies Intelligence, with the aim of ensuring that we can and will develop the technologies needed to provide clean water, better health and cheap food to the world, whether that comes from nanotechnology, industrial biotechnology, or any other emerging technology.  But the project is less about the technology than making sure that the importance of technology is recognised by governments and international organisations. It is no good running around firefighting crises when we could be thinking ahead and averting them. There’s still a long way to go, but we are talking to a number of governments who are keen to host the centre.

(e) I find it interesting that regions/countries (Alberta, Texas, Iran, and increasingly, other Middle Eastern countries) that have been dependent on oil as a source of wealth are heavily invested in nanotechnology. Are there any conclusions to be drawn from that?

Diversification is the name of the game. It is very dangerous for local or national economies to be dependent on a single sector, even when it is one as lucrative as oil & gas. We have done a lot of work in the Middle East, and the issue there is also one of employment. Most of the expertise for oil & gas is imported and in Gulf countries that have gone from fishing villages to major international cities within a generation there is a real need to provide employment for their youthful populations. Nanotechnology and life sciences are seen as industries of the future and are increasingly central to strategy in the Gulf.

Iran is a different case, and it’s a place I have visited several times to discuss nanotechnologies. While the world may have some issues with the Iranian government, the scientists and business people I deal with are just like the rest of us. Iran has some great science going on, and the US embargo has meant that they have had to be quite ingenious to get access to even basic instrumentation such as electron microscopes. However, there’s a large domestic market, and the Iranians are manufacturing everything from scientific instruments to nanomaterials. When the political issues are solved, I think a few people will be surprised by the level of sophistication of Iranian nanoscience. [Note: For an example of what Tim is referring to, see the Fast Company article (Using 3-D Printers To Mock Up New Teeth) by Morgan Glendaniel, as it mentions the impact that Iranian scientists have had on this new nano-enabled technology.)

(f) Is there anything that you couldn’t include in the report but wanted to? For example, a country that doesn’t register yet in terms of its spending or innovation quotient numbers but that you think is quietly gearing up.

Our dataset is very large, and this report is just the tip of the iceberg as we have clients who pay for the detailed information. As a result the published report just concentrates on the top level numbers for the major economies. There are a few places that really stand out though, such as Singapore. The science and technology infrastructure in Singapore is world class, but it is a small country with no real domestic market so the challenge will be commercialising the fruits of its nanotechnology projects. The current strategy is based on licensing to multinationals but that alone won’t justify the investment so I suspect we will see a lot more partnering around the region, leveraging Singaporean technology in regional markets as, for example, SingTel has successfully done.

A real disappointment is India, with their leading Scientist, CNR Rao, being recently quoted as thinking that the country is in danger of missing the boat. [Note: You can find some of the quotes in this July 8, 2011 posting.]  I have spent large amounts of time in India and I know the raw talent is there, but the creaky infrastructure and lack of political will means that they are currently performing way below their potential.

(g) I will be asking a question or two about the Canada and nanotechnology from a global perspective but I’d like to learn a little bit about the project/workshop you delivered for the Canadian government some years ago. As I recall, it was an analysis of the Canadian effort at that point in time. And, are there any plans for future presentations in Canada?

We did some work for the NRC [National Research Council] a few years ago and also attended a few conferences in Canada in the early part of the decade [2000s] but since then I haven’t been back, although judging from the activity that is going on and looking at where Canada is on the rankings then maybe I should spend more time there!

(h) Generally, how would you describe Canada and its role in the global nanotechnology effort?

Our numbers indicate that it is a good place to be, similar to Australia, The Netherlands, Singapore and the Nordic economies, which is what you would expect.  The US, Russia and China are way out in front with huge funding programs, so the way to compete is obviously to be smarter and find niches rather than trying to cover every aspect of what is a huge field. Knowing where you want the economy to go and nurturing the technologies that will help you achieve that is always a good strategy. But governments are usually terrible at picking winners. Most politicians and civil servants are often ill equipped to advise people on how to run a business, so creating the right environment for innovation and then letting entrepreneurs get on with it is probably the best option.

(i) Are there any suggestions you’d make to Canadian policymakers as to improving Canada’s situation?

Think I just answered that above. 😉 In a nutshell it’s not about how much; it’s about how effective the funding is.

(j) How much work is it to write a report like 2011 Global Funding of Nanotechnologies and Its Impact?

It is harder than it looks.  We have been collecting these numbers for the last 10 years but that’s only part of it. We also have to build and maintain relationships with a huge network of government agencies and scientists around the world so that we can understand which numbers are real.  A lot of governments are very happy to announce funding for nanotechnology, but that doesn’t actually mean that it is available and much of what what we try to do is confirm that all the funding we track is real cash and not just a political announcement.

(k) Is there anything you’d like to add?

After 12 years and almost $70 billion in funding we have to keep thinking about why we do science and how we can encourage its results to be translated into both economic and social well-being. The technology transfer process is very inefficient and the path is strewn with many obstacles. If this was a business process someone would have found a way to streamline it by now.

Thank you Tim Harper for going ‘over and above’ in answering my questions.

One final note, in addition to being a ‘serial tech entrepreneur’ (ETA July 18, 2011: I added the word tech to ‘serial entrepreneur’] and CEO (chief executive officer) of Cientifica, Tim co-owns a fashion boutique, Foxbat in the Spitalfields district of London, UK  (proving that people involved in nanotechnology have a broad set of interests).

Interview with Dr. Seyed Gh. Etemad about the International Conference on Nanotechnology: Fundamentals and Applications

I mentioned the 2nd annual International Conference on Nanotechnology: Fundamentals and Applications (ICNFA) in my Sept. 28, 2010 posting. Recently, I decided to interview one of the organizers to find out more about the conference. Dr. Seyed Gholamreza Etemad, who heads the ICNFA 2011 Scientific Committee, very kindly provided answers to my questions. First, a little bit about Dr. Etemad (from the ICNFA’s Keynotes page,

Seyed Gholamreza Etemad is a professor of chemical engineering department at Isfahan University of Technology (IUT-Iran). He is also a co-founder and a member of Center of Excellence of Nanotechnology in Environment at IUT (Iran).Professor Etemad received his B.Sc. and M.Sc. degrees in chemical Engineering from Amirkabir University of Technology (Tehran Polytechnique, Iran). He obtained his PhD from McGill University (Canada) in 1995.

He has served as the chair of the 1st Nanotechnology and Environment Conference in 2007 and the chair of Nanotechnology Workshops in 2009 held at IUT. He acted as the head of the scientific committee for the 1st International Conference on Nanotechnology: Fundamentals and Applications in 2010 (University of Ottawa-Canada). Currently, he is an active member of the scientific and organizing committees of ICNFA 2011. He teaches transport phenomena related courses, renewable energy, and nanotechnology at IUT and university of Ottawa.

Here is a brief preamble from Dr. Etemad describing the conference in more detail before he proceeds to the questions:

Let me first explain a little bit about International ASET Inc. International ASET Inc. was founded in year 2009 as a partnership in Ottawa, Canada. This partnership was formed to perform scientific activities internationally. After holding the First International Conference on Nanotechnology: Fundamentals and Applications in the University of Ottawa, International ASET established an Incorporation and became International ASET Inc.
12 Keynote speakers and approximately 180 papers were presented at ICNFA 2010 in three consecutive days. ICNFA 2010 was able to attract researchers from all around the world.

After successfully holding the first conference, International ASET Inc. decided to organize the 2nd conference of the ICNFA conference series.

a) There are a lot of nanotechnology-themed conferences, why organize
this one?

Nanotechnology is a very fast growing subject which is multi-disciplinary and covers a wide range of scientific fields and applications. Since nanotechnology is a relatively new technology, fundamental approaches are very important. This technology has begun to find different applications in various areas such as: Engineering, Medicine, Arts, Agriculture, and Environment.

The aim of the 2nd International Conference on Nanotechnolgy: Fundamentals and Applications is to gather scholars from all over the world to present advances in the field of nanotechnology and to foster an environment conducive to exchanging ideas and information. This conference will also provide a golden opportunity to develop new collaborations and meet world nanotechnology experts on the fundamentals, applications and products.

b) Usually international conferences are held in various countries over the years but this conference is being held for the second year in a row in Ottawa and the conference is only 2 years old. What is the reasoning behind this?
Since International ASET Inc. was founded in Ottawa, for the first few conferences, we decided to set the venue to the city of Ottawa and the University of Ottawa. We are already negotiating with some of our colleagues in other universities and we will look forward to having some of the future conferences in other countries.

c) Your keynote speakers are covering a very wide range of topics from nanoeducation to nanoelectronics to drug delivery and more. What is the strategy behind offering such a wide range? (In other words, why?)
As mentioned in part (a), Nanotechnology is a multi-disciplinary subject and we expect to attract attendees from different Nanotechnology related areas. Therefore, the Keynotes were chosen from different fields of Nanotechnology.

d) What kinds of results or outcomes did you see as a consequence of the first conference?
ICNFA 2010 brought together Scientists and Researchers from different scientific organizations of various countries and could foster an environment conducive to exchanging ideas and information.

e) Is there anything about the conference that hasn’t made it to the website yet that you are excited about?
We are mostly exited about meeting the engineers, scientists, researchers, and university students from all around the world. We have received interesting manuscripts and we look forward to the presentations of the accepted manuscripts.

f) What was the attendance for the first conference and do you have any idea what numbers to expect for this one?
Approximately 200 people attended the first conference. So far we have received more papers and we expect to have more attendees compared to last year. Our attendees include scientists and engineers from research centers and industries, university professors, and graduate students.

g) Is there anything you’d like to add?
We would like to add that International ASET Inc. is also holding a conference on Environmental Pollution and Remediation (ICEPR’11) this year. This conference is the first of its series and will also be held yearly just like ICNFA.

In the end we would like to thank the University of Ottawa and CSA (Canadian Standards Association) for their support of the ICNFA conference series.

Thank you Dr. Etemad for satisfying my curiousity and, even, anticipating an additional question or two with your preamble. (At the end of almost of every interview, there’s almost always another question or two that I wished I’d had the forethought to ask.)

Nano, the Memphis Zoo, and connecting with kids

Who would have thought that the US Dept. of Agriculture would be awarding the Memphis Zoo $500,000.00 for a project to connect rural schools online for a NanoZoo? Kudos to Dr. Helen Beady, Director of Education, and the staff at the Memphis Zoo for a truly imaginative approach to science education.  From the March 9, 2011 news release,

Dr. Helen Beady, Memphis Zoo Director of Education, applied for this grant [Distance Learning and Telemedicine Grant Program] to help fund the Education Department’s ventures in nanotechnology through a program called “NanoZoo Connects.” This program will initially reach 14 schools in rural Tennessee through distance learning technology.

The Memphis Zoo’s “Discovery Center” will be renovated to become a state-of-the-art studio in which Zoo educators will be able to communicate through a video-bridge with some 7000 students in rural classrooms.

“This is just the beginning,” said Dr. Beady. “This grant will give us the ability to begin a program that will be improved and expanded for years to come. We can’t wait to see what the future holds for distance learning through this new technology.”

It was a story about a lotus leaf at a conference presentation that fired Helen Beady’s imagination three years ago. Scientists working at the nanoscale talk a lot about biomimcry. The lotus leaf is an excellent example of a material that is naturally water-resistant and finding out how the leaf achieves its water-resistant state and using that knowledge to create new textiles is an example of biomimicry.

The notion of biomimicry that helped Dr. Beady to tie together her interest in nanotechnology with exciting children’s interest in the zoo and the animals and integrating STEM (science, technology, engineering, and mathematics) education objectives in a single programme,  NanoZoo.  That project designed for students from kindergarten to high school was launched in August 2010. From the news release,

The concept of nanotechnology as it is taught through “NanoZoo” explores the ways animals and plants can help science improve the way we live and work. For example, students are taught how the Lotus leaf has inspired the development of fabrics that can remain under water for days and not get wet, and how the stick-ability of a Gecko’s foot has motivated the production of tape that allows a robot to walk vertically up a wall.

This new project which is being funded through the Dept. of Agriculture is the NanoZoo Connects distance education project.  From the news release,

“NanoZoo and distance learning bring the Memphis Zoo on the cutting edge of technology,” said Zoo President and CEO, Chuck Brady. “What we learn in the early stages of these initiatives will revolutionize the way we are able to help educate students in Tennessee and, one day, across the globe.

The $500,000. will purchase equipment necessary to make the distance education experience successful. (If you’ve ever struggled with connections and bug-ridden software while trying to pursuing any kind of distance education programme, you can appreciate how important good equipment and software are.) From the news release,

The Memphis Zoo’s “Discovery Center” will be renovated to become a state-of-the-art studio in which Zoo educators will be able to communicate through a video-bridge with some 7000 students in rural classrooms.

What’s striking in this project is the multidisciplinary approach from inception to execution with all of it grounded in the zoo’s basic mission statement: “The Memphis Zoo preserves wildlife through education, conservation and research.” I’ll restate this to say, it’s about discovering and healing the relationship between people, animals, and nature. So by that token, teaching and discussing biomimicry and nanotechnology are not such a far reach as some may believe.

Here’s one last item to illustrate the point. I asked Tiffany Langston, a member of the Memphis Zoo’s marketing and communications department, for something either she or the children have found particularly interesting in the NanoZoo.  Tiffany informed me that the Memphis Zoo is one of only four in the US that have pandas and the only food they will eat is bamboo (40 lbs. per day!). Students at the NanoZoo find out that the fibre within the bamboo stalks features a hexagonal structure at the nanoscale which makes the fibre (at the nanoscale) stronger than steel. Today, scientists are trying to mimic those structures to create strong materials that are produced in a more environmentally friendly fashion than steel.

Meanwhile, Dr. Beady has more projects up her sleeve (from the news release),

The Zoo’s Education Department has recently received a $25,000 environmental grant from the City of Memphis Office of Youth Services and Community Affairs to develop a Science, Technology, Engineering and Math (STEM) field program that focuses on the emerging science nanotechnology. This program will help inner city students draw connections between technology, plants, animals and those things that exist in the “big” world through our “NanoZoo.”

The NanoZoo initiative was celebrated at the Memphis Zoo’s Nano Days event on March 28, 2011 (from the news release),

On March 28, 2011 from 9:00 a.m. until 1:00 p.m. the Memphis Zoo invites you to join us for NanoDays and our One Bazillion Nano Meter Walk (leisurely 1 mile stroll). This event will include hands-on demonstrations which explore how scientists mimic traits of plants and animals to inspire innovations in technology and engineering.

The event attracted US Senator Steve Cohen who had this to say in a recent news release to the Memphis Business Journal (http://www.bizjournals.com/memphis/news/2011/03/28/memphis-zoo-gets-500000-nano-grant.html),

The initiative, NanoZoo Connects!, will help demonstrate how scientists use nanotechnology to mimic particular traits of animals and plants to solve engineering and technological problems, according to a release issued by U.S. Sen. Steve Cohen’s office.

“If we are going to successfully compete in a rapidly changing 21st century global economy, our children must have the necessary tools to get ahead,” Cohen said. “The NanoZoo Connects! program will help us accomplish such a goal.”

Dr. Helen Beady told me that she drew on her experience as a former business owner, where she was in the position of trying to hire people who didn’t have the necessary skills or education, to develop the NanoZoo programme. Multidisciplinary in nature. Dr. Beady has hired an engineer and a PhD. in biochemistry to assist with further developing the NanoZoo.

All of this may or may not lead to ‘successful competition in the 21st century global economy’ but it certainly will lead to children learning more about animals and nature and how we might all better co-exist on this planet.

Mark MacLachlan talks about beetles, biomimcry, and nanocrystalline cellulose

After mentioning the Café Scientifique talk coming up on Tuesday, March 29, 2011 at Vancouver’s (Canada) Railway Club in my March 24, 2011 posting (http://www.frogheart.ca/?p=3171), I’m happy to say that Mark MacLachlan, the featured speaker, has answered a few questions about himself, his work and what he plans to talk about. Here he is,

(a) Could you tell me a little bit about yourself and why you’re giving a talk for Café Scientifique?

I grew up in Quesnel then obtained my BSc degree at UBC and my PhD at the University of Toronto. After a 2 year post-doc at MIT, I returned to UBC where I have been a chemistry professor since 2001.

My research is in materials chemistry – we develop new materials that “do things”. That might include materials that change properties when exposed to another chemical (i.e., sensing) or light, or materials that can store gases in their interior. We are excited about developing new materials with unusual properties.

(b) How did you decide on your topic? Are people demanding to know about biomimcry?

I was invited to give a talk on our work we published in Nature on the coloured glasses. As these materials mimic the structures of beetle shells, I thought that would be an interesting angle for a more general talk.

(c) The description for your upcoming talk in common with the description of a paper you and your team published Nov. 2010 in Nature mentions irridescent beetle exoskeletons. Which came first, an interest in irridescence or an interest in nanocrystalline cellulose (or is nanocrystals of cellulose)? And, how was the connection between the two made?

An interest in NCC came first. We were working with NCC to develop composites of NCC/glass when we discovered the iridescent materials. It was then a few months later that we made the connection to beetle exoskeletons.

(d) What can your audience expect? Will you be singing about biomimicry and/or nanocrystalling cellulose or offering a mixed media show as part of the talk?

I will be talking about biomimicry a little and mostly about the materials. I plan to take a few samples with me.

e) Is your talk connected to the Nano Days events which run from March 26 – April 3, 2011 or is it coincidence?

Just a coincidence – this is the first I’ve heard of Nano Days!

f) Is there anything you’d like to add?

I’ve never been to Café Scientifique before and I am looking forward to this opportunity to share some science!

Thank you Mark MacLachlan. If you want to know more, check out the Railway Club at 579 Dunsmuir St. The event starts at 7:30 pm on Tuesday, March 29, 2011.

Arts scholar in residence at National Institute of Technology: Heather Graves

Early in the new year, the University of Alberta announced the appointment of its first Scholar in Residence for Arts in Nanotechnology, Heather Graves (mentioned in my Jan. 19, 2011 posting). I contacted Dr. Graves for an interview which she very kindly gave. Before proceeding here’s a little bit of biographical information from the WRS webpage) about her [ETA Mar.11.11: photo and information about WRS webpage added],

Heather Graves is an Associate Professor of Writing Studies and the Department English and Film Studies. She is the author of Rhetoric in(to) Science: Style as Invention in Inquiry (Cresskill, NJ: Hampton, 2005); co-editor with Roger Graves of Writing Centres, Writing Seminars, Writing Culture: Teaching Writing in Anglo-Canadian Universities (Winnipeg: Inkshed Publications, 2006) and Inkshed: Newsletter of the Canadian Assoication for the Study of Language and Learning; and co-author of the Canadian Edition of The Brief Penguin Handbook (Pearson/Longman, 2007) and A Strategic Guide to Technical Communication (Peterborough: Broadview, 2007). …

As co-president of the Canadian Association for the Study of Discourse and Writing (CASDW)/ L’Association canadienne de rédactologie (ACR) (formerly the Canadian Association of Teachers of Technical Writing (CATTW)/ L’Association canadienne de professeurs de rédaction technique and scientific (ACPRTS), she has served as program chair of the annual conference held at the Congress of the Humanities and Social Sciences.

Professor Heather Graves, Canada's new Arts Scholar in Residence in Nanotechnology (photo from WRS website)

Heather will be working with scientists at the National Institute of Nanotechnology (NINT) which is located in Edmonton at the University of Alberta. The interview starts here:

(a) I was thrilled to see that a ‘scholar in residence for arts research in nanotechnology’. How do you feel about the appointment?

It’s a real opportunity to be invited into a community of practicing scientists. A number of them have been quite generous with their time to help me with their project. I have worked with scientists before but this is the first time that the invitation came, basically, from them, rather than me inviting myself in. It is wonderful to learn new things and to extend my understanding of science and how science people use rhetoric and writing in their work and professional lives.

(b) I believe this is the first such appointment in Canada, is that right? Why was the position created?

I am not aware of any other such appointments (there is only one National Institute in Canada, but the various centres for nanotechnology being built at various Canadian universities could also follow suit). I think the position was created because someone at NINT wished to develop closer links between Arts and Science, specifically nanoscience/technology. The hope is that greater knowledge of what scientists are doing with their research in nanotechnology will get a bit more publicity through this position (it will get more play on campus for sure, and likely a bit more exposure to the broader public). The position is sponsored by the Vice President of Research here at U of A but I’m not exactly clear on where the money came from (to buy out my teaching for this term, so give me some development money with which I am employing a Graduate Research Assistant, and a modest travel budget to present a conference paper or two). I expect the university and the National Institute for Nanotechnology (NINT) are sharing the costs.

(c) What will you be doing as a ‘scholar in residence for arts research in nanotechnology’? (i. e., Are there deliverables for this project and what might they be?)

I am conducting a research project on language and writing in the work of scientists doing research in nanotechnology/nanoscience. There are several strands to the project: interviews with scientists about their research and about how they use writing in their professional work and how they teach writing to the graduate students who work with them; attending meetings between supervisors and their graduate students as they meet regularly to talk about their progress on individual experimental work; attending seminars by visiting researchers about their recent work; and analyzing drafts of research reports to identify the discursive conventions of the discipline, including the features of argument structure. My focus is on how scientists use language and writing to communicate about their research; how they understand the process of drafting a convincing argument for their interpretations of the research findings, and how they structure that argument; and how newcomers to the field acculturate into the norms and conventions of the discourse in this field. The discourse conventions of nanotechnology (as an emerging discipline) are still being negotiated: they evolve out of the collaborative efforts of the interdisciplinary scientists who work together on various projects, as well as between writers and editors for scholarly journals in nanotechnology. I’m interested in documenting, as far as possible, some of this negotiation from the scientists’ perspectives and from studies of their published (and in some cases draft) reports of research. This study also analyses the linguistic constructions that the scientists use to conceptualize and communicate the scientific phenomena that they are studying. Research on the nanoscale is mediated by both technology and language, making it a fascinating site for exploring how these mediations are translated into knowledge and eventually commercial products. I expect that these different strands of the project will result in a series of conference papers and then several academic articles or even a book-length manuscript on rhetoric and nanotechnology. I also expect that some of these insights will be valuable in writing textbooks on writing in disciplines other than Arts and Humanities. I may also write some articles on nanotechnology for more popular audiences.

(d) What aspects of your previous work are you bringing to this position (e.g., rhetorical function of visuals in science research and/or model of argumentation in scientific discourse)?

Much all the work that I’ve done earlier on rhetoric of science and on argument in the disciplines is relevant to this project. For example, many discussions of scientific phenomena take place based on visuals, so a better understanding of relationship between the visuals and their rhetorical purpose is crucial to understanding the processes of knowledge creation engaged in by scientists. The visuals in science generally function as evidence supporting the claims made for new knowledge in the arguments constructed in oral presentations of work as well as in journal publications. These aspects tie in to my long-standing interest in argument in the disciplines and especially science-related disciplines. Since I also teach writing to first year science majors and to graduate students in science disciplines, this study will enable me to develop new and better teaching materials for these audiences of learners. So on a practical level this research project could well translate eventually into better instructional material for writers in science and better writers of scientific discourse in Canada.

(e) Do you have colleagues, i.e. other ‘scholars in residence for arts research in nanotechnology’, internationally and who might they be? In other words, how does this position fit within the international scene?

I am not aware of any other “scholars in residence for arts research in nanotechnology” elsewhere at this point. Please let me know if you encounter any more! I am working pretty much in isolation; of course it would be great to have colleagues to talk to who are in similar circumstances but when you are carving your own path it’s also freeing, in a way, because there is no standard procedure or approach. You can invent your project and its execution any way you want. This is generally how I have proceeded in the past because my area of interest (the study of the language and rhetoric/writing of working scientists) was sparsely populated by other scholars, especially from 1995 to the early 2000s. In the last five years or so, however, I have met a number of other rhetoric of science and writing in science scholars who are addressing some of the same issues.

Beyond the “Scholar in Residence . . .” title, however, I know there is significant interest in nanoscience and nanotechnology from many different types of people from both academic and more popular perspectives, but this collaboration between the University of Alberta and the National Institute for Nanotechnology does seem like a brand new idea. It certainly encourages interaction between two areas that don’t generally mix professionally, and it will be interesting to see what comes of this interaction in the long term, since the “Scholar in Residence for Arts Research in Nanotechnology” pilot project is slated to run for two more years after me and perhaps to be made permanent if it is deemed a success. I look forward to also hearing about subsequent research projects that follow mine. Perhaps other Centres for Nanotechnology across Canada and around the world might follow the lead here by University of Alberta and NINT. I certainly hope so.

(f) Is there anything you’d like to add?

I think many people have little idea about what is required to do this kind of research project successfully at least from the perspective of the number of hours it takes. You do have to commit significant numbers regularly over a period of time to get to know anyone in the community and to gain a reasonable level of understanding of the community. This means just hanging out for several hours a day as often as possible and collecting information as you hang out. The more information you collect the better you understand your area of study and the more data you have to work with, but processing all of this information also becomes a huge task. For example, sifting through interviews and research presentations and meeting transcripts takes a lot of time and energy. Transcribing digital recordings of key interchanges also takes time (although voice recognition software has improved immensely in the last few years, one still can’t devote one-third of a half-hour interview with a busy person to getting the technology up to speed). What I’m trying to say is that you cannot do this kind of research while also teaching a full load of classes; this type of research is only practical and possible if you have the luxury of time, which is what a program such as the Scholar in Residence for Arts Research in Nanotechnology provides. More people might conduct this kind of research if such a program were more widely available but in the absence of this type of support other types of less time-intensive research has to be undertaken, changing the types of research questions that you can ask and re-directing to somewhere else the advance of knowledge from this area.

Thank you Heather. I look forward to hearing and reading more about your work as the project progresses. I wish you the best of luck with it.
