Science policy updates (INGSA in Canada and SCWIST)

I had just posted my Aug. 30, 2021 piece (4th International Conference on Science Advice to Governments (INGSA2021) August 30 – September 2, 2021) when the organization issued a news release, which was partially embargoed. By the time this is published (after 8 am ET on Wednesday, Sept. 1, 2021), the embargo will have lifted and i can announce that Rémi Quirion, Chief Scientist of Québec (Canada), has been selected to replace Sir Peter Gluckman (New Zealand) as President of INGSA.

Here’s the whole August 30, 2021 International Network for Government Science Advice (INGSA) news release on EurekAlert, Note: This looks like a direct translation from a French language news release, which may account for some unusual word choices and turns of phrase,

What? 4th International Conference on Science Advice to Governments, INGSA2021.

Where? Palais des Congrès de Montréal, Québec, Canada and online at www.ingsa2021.org

When? 30 August – 2 September, 2021.

CONTEXT: The largest ever independent gathering of interest groups, thought-leaders, science advisors to governments and global institutions, researchers, academics, communicators and diplomats is taking place in Montreal and online. Organized by Prof Rémi Quirion, Chief Scientist of Québec, speakers from over 50 countries[1] from Brazil to Burkina Faso and from Ireland to Indonesia, plus over 2000 delegates from over 130 countries, will spotlight what is really at stake in the relationship between science and policy-making, both during crises and within our daily lives. From the air we breathe, the food we eat and the cars we drive, to the medical treatments or the vaccines we take, and the education we provide to children, this relationship, and the decisions it can influence, matter immensely.  

Prof Rémi Quirion, Conference Organizer, Chief Scientist of Québec and incoming President of INGSA added: “For those of us who believe wholeheartedly in evidence and the integrity of science, the past 18 months have been challenging. Information, correct and incorrect, can spread like a virus. The importance of open science and access to data to inform our UN sustainable development goals discussions or domestically as we strengthen the role of cities and municipalities, has never been more critical. I have no doubt that this transparent and honest platform led from Montréal will act as a carrier-wave for greater engagement”.

Chief Science Advisor of Canada and Conference co-organizer, Dr Mona Nemer, stated that: “Rapid scientific advances in managing the Covid pandemic have generated enormous public interest in evidence-based decision making. This attention comes with high expectations and an obligation to achieve results. Overcoming the current health crisis and future challenges will require global coordination in science advice, and INGSA is well positioned to carry out this important work. Canada and our international peers can benefit greatly from this collaboration.”

Sir Peter Gluckman, founding Chair of INGSA stated that: “This is a timely conference as we are at a turning point not just in the pandemic, but globally in our management of longer-term challenges that affect us all. INGSA has helped build and elevate open and ongoing public and policy dialogue about the role of robust evidence in sound policy making”.

He added that: “Issues that were considered marginal seven years ago when the network was created are today rightly seen as central to our social, environmental and economic wellbeing. The pandemic highlights the strengths and weaknesses of evidence-based policy-making at all levels of governance. Operating on all continents, INGSA demonstrates the value of a well-networked community of emerging and experienced practitioners and academics, from countries at all levels of development. Learning from each other, we can help bring scientific evidence more centrally into policy-making. INGSA has achieved much since its formation in 2014, but the energy shown in this meeting demonstrates our potential to do so much more”.

Held previously in Auckland 2014, Brussels 2016, Tokyo 2018 and delayed for one year due to Covid, the advantage of the new hybrid and virtual format is that organizers have been able to involve more speakers, broaden the thematic scope and offer the conference as free to view online, reaching thousands more people. Examining the complex interactions between scientists, public policy and diplomatic relations at local, national, regional and international levels, especially in times of crisis, the overarching INGSA2021 theme is: “Build back wiser: knowledge, policy & publics in dialogue”.

The first three days will scrutinize everything from concrete case-studies outlining successes and failures in our advisory systems to how digital technologies and AI are reshaping the profession itself. The final day targets how expertize and action in the cultural context of the French-speaking world is encouraging partnerships and contributing to economic and social development. A highlight of the conference is the 2 September announcement of a new ‘Francophonie Science Advisory Network’.       

Prof. Salim Abdool Karim, a member of the World Health Organization’s Science Council, and the face of South Africa’s Covid-19 science, speaking in the opening plenary outlined that: “As a past anti-apartheid activist now providing scientific advice to policy-makers, I have learnt that science and politics share common features. Both operate at the boundaries of knowledge and uncertainty, but approach problems differently. We scientists constantly question and challenge our assumptions, constantly searching for empiric evidence to determine the best options. In contrast, politicians are most often guided by the needs or demands of voters and constituencies, and by ideology”.

He added: “What is changing is that grass-roots citizens worldwide are no longer ill-informed and passive bystanders. And they are rightfully demanding greater transparency and accountability. This has brought the complex contradictions between evidence and ideology into the public eye. Covid-19 is not just a disease, its social fabric exemplifies humanity’s interdependence in slowing global spread and preventing new viral mutations through global vaccine equity. This starkly highlights the fault-lines between the rich and poor countries, especially the maldistribution of life-saving public health goods like vaccines. I will explore some of the key lessons from Covid-19 to guide a better response to the next pandemic”.

Speaking on a panel analysing different advisory models, Prof. Mark Ferguson, Chair of the European Innovation Council’s Advisory Board and Chief Science Advisor to the Government of Ireland, sounded a note of optimism and caution in stating that: “Around the world, many scientists have become public celebrities as citizens engage with science like never before. Every country has a new, much followed advisory body. With that comes tremendous opportunities to advance the status of science and the funding of scientific research. On the flipside, my view is that we must also be mindful of the threat of science and scientists being viewed as a political force”.

Strength in numbers

What makes the 4th edition of this biennial event stand out is the perhaps never-before assembled range of speakers from all continents working at the boundary between science, society and policy willing to make their voices heard. In a truly ‘Olympics’ approach to getting all stakeholders on-board, organisers succeeded in involving, amongst others, the UN Office for Disaster Risk Reduction, the United Nations Development Programme, UNESCO and the OECD. The in-house science services of the European Commission and Parliament, plus many country-specific science advisors also feature prominently.

As organisers foster informed debate, we get a rare glimpse inside the science advisory worlds of the Comprehensive Nuclear Test Ban Treaty Organisation, the World Economic Forum and the Global Young Academy to name a few. From Canadian doctors, educators and entrepreneurs and charitable foundations like the Welcome Trust, to Science Europe and media organisations, the programme is rich in its diversity. The International Organisation of the Francophonie and a keynote address by H.E. Laurent Fabius, President of the Constitutional Council of the French Republic are just examples of two major draws on the final day dedicated to spotlighting advisory groups working through French. 

INGSA’s Elections: New Canadian President and Three Vice Presidents from Chile, Ethiopia, UK

The International Network for Government Science Advice has recently undertaken a series of internal reforms intended to better equip it to respond to the growing demands for support from its international partners, while realising the project proposals and ideas of its members.

Part of these reforms included the election in June, 2021 of a new President replacing Sir Peter Gluckman (2014 – 2021) and the creation of three new Vice President roles.

These results will be announced at 13h15 on Wednesday, 1st September during a special conference plenary and awards ceremony. While noting the election results below, media are asked to respect this embargo.

Professor Rémi Quirion, Chief Scientist of Québec (Canada), replaces Sir Peter Gluckman (New Zealand) as President of INGSA.
 

Professor Claire Craig (United Kingdom), CBE, Provost of Queen’s College Oxford and a member of the UK government’s AI Council, has been elected by members as the inaugural Vice President for Evidence.
 

Professor Binyam Sisay Mendisu (Egypt), PhD, Lecture at the University of Addis Ababa and Programme Advisor, UNESCO Institute for Building Capacity in Africa, has been elected by members as the inaugural Vice President for Capacity Building.
 

Professor Soledad Quiroz Valenzuela (Chile), Science Advisor on Climate Change to the Ministry of Science, Technology, Knowledge and Innovation of the government of Chile, has been elected by members as the Vice President for Policy.

Satellite Events: From 7 – 9 September, as part of INGSA2021, the conference is partnering with local,  national and international organisations to ignite further conversations about the science/policy/society interface. Six satellite events are planned to cover everything from climate science advice and energy policy, open science and publishing during a crisis, to the politicisation of science and pre-school scientific education. International delegates are equally encouraged to join in online. 

About INGSA: Founded in 2014 with regional chapters in Africa, Asia and Latin America and the Caribbean, INGSA has quicky established an important reputation as aa collaborative platform for policy exchange, capacity building and research across diverse global science advisory organisations and national systems. Currently, over 5000 individuals and institutions are listed as members. Science communicators and members of the media are warmly welcomed to join.

As the body of work detailed on its website shows (www.ingsa.org) through workshops, conferences and a growing catalogue of tools and guidance, the network aims to enhance the global science-policy interface to improve the potential for evidence-informed policy formation at sub-national, national and transnational levels. INGSA operates as an affiliated body of the International Science Council which acts as trustee of INGSA funds and hosts its governance committee. INGSA’s secretariat is based in Koi Tū: The Centre for Informed Futures at the University of Auckland in New Zealand.

Au-delà de l’apparence :

des femmes de courage et de résilience en STIM

Dans le cadre de la semaine de l’égalité des sexes au Canada, ce forum de la division québécoise de la Société pour les femmes canadiennes en science et technologie (la SCWIST) mettra en vedette quatre panélistes inspirantes avec des parcours variés qui étudient ou travaillent en science, technologie, ingénierie et mathématiques (STIM) au Québec. Ces femmes immigrantes ont laissé leurs proches et leurs pays d’origine pour venir au Québec et contribuer activement à la recherche scientifique québécoise.

The ‘Art and Science Policy-Making Go Together’ talk seems to be aimed at persuasion and is not likely to offer any insider information as to how the BC life sciences effort is progressing. For a somewhat less rosy view of science and policy efforts, you can check out my August 23, 2021 posting, Who’s running the life science companies’ public relations campaign in British Columbia (Vancouver, Canada)?; scroll down to ‘The BC biotech gorillas’ subhead for more about Acuitas and some of the other life sciences companies in British Columbia (BC).

For some insight into how competitive the scene is here in BC, you can see my August 20, 2021 posting (Getting erased from the mRNA/COVID-19 story) about Ian MacLachlan.

‘What becomes of the broken-hearted?’ Trinity College Dublin scientists may have an answer

While Valentine’s Day as celebrated here in Canada and elsewhere (but not everywhere) on February 14 of each year is usually marked in a purely joyous fashion,I’m going to focus on heartbreak. Here is one of the greatest versions of ‘What becomes of the broken-hearted?’ Then, repair follows in the context of some cardiac research coming out of Ireland,

Thank you Joan Osborne and the Funk Brothers. If you haven’t seen ‘Standing in the shadows of Motown’, you may want to make a point of it.

As for the musical question in the headline, researchers at Trinity College Dublin may have an answer of sorts. A February 13, 2020 Trinity College Dublin press release (also on EurekAlert) describes how broken hearts can be mended,

Bioengineers from Trinity College Dublin, Ireland, have developed a prototype patch that does the same job as crucial aspects of heart tissue.

Their patch withstands the mechanical demands and mimics the electrical signalling properties that allow our hearts to pump blood rhythmically round our bodies.

Their work essentially takes us one step closer to a functional design that could mend a broken heart.

One in six men and one in seven women in the EU will suffer a heart attack at some point in their lives. Worldwide, heart disease kills more women and men – regardless of race, than any other disease.

Cardiac patches lined with heart cells can be applied surgically to restore heart tissue in patients who have had damaged tissue removed after a heart attack and to repair congenital heart defects in infants and children. Ultimately, though, the goal is to create cell-free patches that can restore the synchronous beating of the heart cells, without impairing the heart muscle movement.

The bioengineers report their work, which takes us one step closer to such a reality, in the journal Advanced Functional Materials.

Michael Monaghan, ussher assistant professor in biomedical engineering at Trinity, and senior author on the paper, said:

“Despite some advances in the field, heart disease still places a huge burden on our healthcare systems and the life quality of patients worldwide. It affects all of us either directly or indirectly through family and friends. As a result, researchers are continuously looking to develop new treatments which can include stem cell treatments, biomaterial gel injections and assistive devices.”

“Ours is one of few studies that looks at a traditional material, and through effective design allows us to mimic the direction-dependent mechanical movement of the heart, which can be sustained repeatably. This was achieved through a novel method called ‘melt electrowriting’ and through close collaboration with the suppliers located nationally we were able to customise the process to fit our design needs.”

This work was performed in the Trinity Centre for Biomedical Engineering, based in the Trinity Biomedical Sciences Institute in collaboration with Spraybase®, a subsidiary of Avectas Ltd. It was funded by Enterprise Ireland through the Innovation Partnership Program (IPP).

Dr Gillian Hendy, director of Spraybase® is a co-author on the paper. Dr Hendy commended the team at Trinity on the work completed and advancements made on the Spraybase® Melt Electrowriting (MEW) System. The success achieved by the team highlights the potential applications of this novel technology in the cardiac field and succinctly captures the benefits of industry and academic collaboration, through platforms such as the IPP.

Engineering replacement materials for heart tissue is challenging since it is an organ that is constantly moving and contracting. The mechanical demands of heart muscle (myocardium) cannot be met using polyester-based thermoplastic polymers, which are predominantly the approved options for biomedical applications.

However, the functionality of thermoplastic polymers could be leveraged by its structural geometry. The bioengineers then set about making a patch that could control the expansion of a material in multiple directions and tune this using an engineering design approach.

The patches were manufactured via melt electrowriting – a core technology of Spraybase® – which is reproducible, accurate, and scalable. The patches were also coated with the electroconductive polymer polypyrrole to provide electrical conductivity while maintaining cell compatibility.

The patch withstood repeated stretching, which is a dominant concern for cardiac biomaterials, and showed good elasticity, to accurately mimic that key property of heart muscle.

Professor Monaghan added:

“Essentially, our material addresses a lot of requirements. The bulk material is currently approved for medical device use, the design accommodates the movement of the pumping heart, and has been functionalised to accommodate signaling between isolated contractile tissues.”

“This study currently reports the development of our method and design, but we are now looking forward to furthering the next generation of designs and materials with the eventual aim of applying this patch as a therapy for a heart attack.”

Dr Dinorath Olvera, Trinity, first author on the paper, added:

“Our electroconductive patches support electrical conduction between biological tissue in an ex vivo model. These results therefore represent a significant step towards generating a bioengineered patch capable of recapitulating aspects of heart tissue – namely its mechanical movement and electrical signalling.”

Science inspired by superheroes, Ant-Man and the Wasp

It’s interesting to see scientists take science fiction and use it as inspiration; something which I think happens more often than we know. After all, when someone asks where you got an idea, it can be difficult to track down the thought process that started it all.

Scientists at Virginia Tech (Virginia Polytechnic Institute and State University) are looking for a new source of inspiration after offering a close examination of how insect-size superheroes, Ant-Man and the Wasp might breathe. From a December 11, 2018 news item on phys.org (Note: A link has been removed),

Max Mikel-Stites and Anne Staples were searching for a sequel.

This summer, Staples, an associate professor in the Department of Biomedical Engineering and Mechanics in the College of Engineering, and graduate student Mikel-Stites published a paper in the inaugural issue of the Journal of Superhero Science titled, “Ant-Man and the Wasp: Microscale Respiration and Microfluidic Technology.”

Now, they needed a new hero.

The two were working with a team of graduate students, brainstorming who could be the superhero subject for their next scientific inquiry. Superman? Batgirl? Aquaman?

Mikel-Stites lobbied for an investigation of Dazzler’s sonoluminescent powers. Staples was curious how Mera, The Princes sof Atlantis, used her hydrokinetic powers.

It turns out, comic books are a great inspiration for scientific discovery.

This month, Mikel-Stites is presenting the findings of their paper at the American Physical Society’s Division of Fluid Dynamics meeting.

The wonder team’s paper looked at how Ant-Man and the Wasp breathe when they shrink down to insect-size and Staples’ lab studied how fluids flow in nature. Insects naturally move fluids and gases efficiently at tiny scales. If engineers can learn how insects breathe, they can use the knowledge to invent new microfluidic technologies.

A November 2018 Virginia Tech news release (also on EurekAlert but published on December 11, 2018) by Nancy Dudek describes the ‘Ant-Man and Wasp respiratory project’ before revealing the inspiration for the team’s new project,

“Before the 2018 ‘Ant-Man and the Wasp’ movie, my lab was already wondering about insect-scale respiration,” said Staples. “I wanted to get people to appreciate different breathing mechanisms.”

For most of Mikel-Stites’ life, he had been nit-picking at the “science” in science-fiction movies.

“I couldn’t watch ‘Armageddon’ once they got up to space station Mir and there was artificial gravity. Things like that have always bothered me. But for ‘Ant-Man and the Wasp’ it was worse,” he said.

Staples and Mikel-Stites decided to join forces to research Ant-Man’s microscale respiration.

Mikel-Stites was stung by what he dubbed “the altitude problem or death-zone dilemma.” For Ant-Man and the Wasp to shrink down to insect size and still breathe, they would have to overcome an atmospheric density similar to the top of Mt. Everest. Their tiny bodies would also require higher metabolisms. For their survival, the Marvel comic universe had to give Ant-Man and the Wasp superhero technologies.

“I thought it would be fun to find a solution for how this small-scale respiration would work,”said Mikel-Stites.”I started digging through Ant-Man’s history. I looped through scenes in the 2015 movie where we could address the physics. Then I did the same thing with trailers from the 2018 movie. I used that to make a list of problems and a list of solutions.”

Ant-Man and the Wasp solve the altitude problem with their superhero suits. In their publication, Mikel-Stites and Staples write that the masks in Ant-Man and the Wasp’s suits contain “a combination of an air pump, a compressor, and a molecular filter including Pym particle technology,” that allows them to breathe while they are insect-sized.

“This publication showed how different physics phenomena can dominate at different size scales, how well-suited organisms are for their particular size, and what happens when you start altering that,” said Mikel-Stites. “It also shows that Hollywood doesn’t always get it right when it comes to science!”

Their manuscript was accepted by the Journal of Superhero Science before the release of the sequel, “Ant-Man and the Wasp.” Mikel-Stites was concerned the blockbuster might include new technologies or change Ant-Man’s canon. If the Marvel comic universe changed between the 2015 ‘Ant-Man’ movie and the sequel, their hypotheses would be debunked and they would be forced to retract their paper.

“I went to the 2018 movie before the manuscript came out in preprint so that if the movie contradicted us we could catch it. But the 2018 movie actually supported everything we had said, which was really nice,” said Mikel-Stites. Most moviegoers simply watched the special effects and left the theater entertained. But Mikel-Stitesleft the movie with confirmation of the paper’s hypotheses.

The Staples lab members are not the only ones interested in tiny technologies. From lab-on-a-chip microfluidic devices to nanoparticles that deliver drugs directly to cells, consumers will ultimately benefit from this small scientific field that delivers big results.

“In both the movies and science, shrinking is a common theme and has been for the last 50-60 years. This idea is something that we all like to think about. Given enough time, we can reach the point where science can take it from the realms of magic into something that we actually have an explanation for,” Mikel-Stites said.

In fact, the Staples lab group has already done just that.

While Mikel-Stites is presenting his superhero science at the APS meeting, his colleague Krishnashis Chatterjee, who recently completed his Ph.D. in engineering mechanics will be presenting his research on fabricating and testing four different insect-inspired micro-fluidic devices.

From fiction to function, the Staples lab likes to have fun along the way.

“I think that it is really important to connect with people and be engaged in science with topics they already know about. With this superhero science paper I wanted to support this mission,” Staples said.

And who did the lab mates choose for their next superhero science subject? The Princess of Atlantis, Mera. They hope they can publish another superhero science paper that really makes waves.

And, just because the idea of a superhero science journal tickles my fancy, here’s a little more from the journal’s About webpage,

Serial title
Superhero Science and Technolog

Focus and Scope
Superhero Science and Technology (SST) is multi-disciplinary journal that considers new research in the fields of science, technology, engineering and ethics motivated and presented using the superhero genre.

The superhero genre has become one of the most popular in modern cinema. Since the 2000 film X-Men, numerous superhero-themed films based on characters from Marvel Comics and DC Comics have been released. Films such as The Avengers, Iron Man 3, Avengers: Age of Ultron and Captain America: Civil War have all earned in excess of $1 billion dollars at the box office, thus demonstrating their relevance in modern society and popular culture.

Of particular interest for Superhero Science and Technology are articles that motivate new research by using the platform of superheroes, supervillains, their superpowers, superhero/supervillain exploits in Hollywood blockbuster films or superhero/supervillain adventures from comic books. Articles should be written in a manner so that they are accessible to both the academic community and the interested non-scientist i.e. general public, given the popularity of the superhero genre.

Dissemination of content using this approach provides a potential for the researcher to communicate their work to a larger audience, thus increasing their visibility and outreach within and outside of the academic domain.

The scope of the journal includes but is not limited to:
Genetic editing approaches;
Innovations in the field of robotics;
New and advanced materials;
Additive Manufacturing i.e. 3D printing, for both bio and non-bio applications;
Advancements in bio-chemical processing;
Biomimicry technologies;
Space physics, astrophysical and cosmological research;
Developments in propulsion systems;
Responsible innovation;
Ethical issues pertaining to technologies and their use for human enhancement or augmentation.

Cellulose biosensor heralds new bioimaging approach to tissue engineering

I keep an eye on how nanocellulose is being used in various applications and I’m not sure that this cellulose biosensor quite fits the bill as nanocellulose, nonetheless, it’s interesting and that’s enough for me. From a December 12, 2018 Sechenov University (Russia) press release on EurekAlert,

I.M. Sechenov First Moscow State Medical University teamed up together with Irish colleagues to develop a new imaging approach for tissue engineering. The team produced so-called ‘hybrid biosensor’ scaffold materials, which are based on cellulose matrices labeled with pH- and calcium-sensitive fluorescent proteins. These materials enable visualization of the metabolism and other important biomarkers in the engineered artificial tissues by microscopy. The results of the work were published in the Acta Biomaterialia journal.
The success of tissue engineering is based on the use of scaffold matrices – materials that support the viability and direct the growth of cells, tissues, and organoids. Scaffolds are important for basic and applied biomedical research, tissue engineering and regenerative medicine, and are promising for development of new therapeutics. However, the ability ‘to see’ what happens within the scaffolds during the tissue growth poses a significant research challenge

“We developed a new approach allowing visualization of scaffold-grown tissue and cells by using labeling with biosensor fluorescent proteins. Due to the high specificity of labeling and the use of fluorescence microscopy FLIM, we can quantify changes in pH and calcium in the vicinity of cells,” says Dr. Ruslan Dmitriev, Group Leader at the University College Cork and the Institute for Regenerative Medicine (I.M. Sechenov First Moscow State Medical University).
To achieve the specific labeling of cellulose matrices, researchers used well-known cellulose-binding proteins. The use of extracellular pH- and calcium-sensitive biosensors allow for analysis of cell metabolism: indeed, the extracellular acidification is directly associated with the balance of cell energy production pathways and the glycolytic flux (release of lactate). It is also a frequent hallmark of cancer and transformed cell types. On the other hand, calcium plays a key role in the extra- and intracellular signaling affecting cell growth and differentiation.

The approach was tested on different types of cellulose matrices (bacterial and produced from decellularised plant tissues) using 3D culture of human colon cancer cells and stem-cell derived mouse small intestinal organoids. The scaffolds informed on changes in the extracellular acidification and were used together with the analysis of real-time oxygenation of intestinal organoids. The resulting data can be presented in the form of colour maps, corresponding to the areas of cell growth within different microenvironments.

“Our results open new prospects in the imaging of tissue-engineered constructs for regenerative medicine. They enable deeper understanding of tissue metabolism in 3D and are also highly promising for commercialisation,” concludes Dr. Dmitriev.

The researchers have provided an image to illustrate their work,

Tracks of my tears could power smartphone?

So far the researchers aren’t trying to power anything with tears but they have discovered that tears could be used to generate electricity (from an Oct. 2, 2017 news item on phys.org),

A team of Irish scientists has discovered that applying pressure to a protein found in egg whites and tears can generate electricity. The researchers from the Bernal Institute, University of Limerick (UL), Ireland, observed that crystals of lysozyme, a model protein that is abundant in egg whites of birds as well as in the tears, saliva and milk of mammals can generate electricity when pressed. Their report is published today (October 2) in the journal, Applied Physics Letters.

An Oct. 2, 2017 University of Limerick press release (also on EurekAlert), which originated the news item, offers additional detail,

The ability to generate electricity by applying pressure, known as direct piezoelectricity, is a property of materials such as quartz that can convert mechanical energy into electrical energy and vice versa. Such materials are used in a variety of applications ranging from resonators and vibrators in mobile phones to deep ocean sonars and ultrasound imaging. Bone, tendon and wood are long known to possess piezoelectricity.

“While piezoelectricity is used all around us, the capacity to generate electricity from this particular protein had not been explored. The extent of the piezoelectricity in lysozyme crystals is significant. It is of the same order of magnitude found in quartz. However, because it is a biological material, it is non toxic so it could have many innovative applications such as electroactive anti-microbial coatings for medical implants,” explained Aimee Stapleton, the lead author and an Irish Research Council EMBARK Postgraduate Fellow in the Department of Physics and Bernal Institute of UL.

Crystals of lysozyme are easy to make from natural sources. “The high precision structure of lysozyme crystals has been known since 1965,” said structural biologist at UL and co-author Professor Tewfik Soulimane.
“In fact, it is the second protein structure and the first enzyme structure that was ever solved,” he added, “but we are the first to use these crystals to show the evidence of piezoelectricity”.

According to team leader Professor Tofail Syed of UL’s Department of Physics, “Crystals are the gold-standard for measuring piezoelectricity in non-biological materials. Our team has shown that the same approach can be taken in understanding this effect in biology. This is a new approach as scientists so far have tried to understand piezoelectricity in biology using complex hierarchical structures such as tissues, cells or polypeptides rather than investigating simpler fundamental building blocks”.

The discovery may have wide reaching applications and could lead to further research in the area of energy harvesting and flexible electronics for biomedical devices. Future applications of the discovery may include controlling the release of drugs in the body by using lysozyme as a physiologically mediated pump that scavenges energy from its surroundings. Being naturally biocompatible and piezoelectric, lysozyme may present an alternative to conventional piezoelectric energy harvesters, many of which contain toxic elements such as lead.

Professor Luuk van der Wielen, Director of Bernal Institute and Bernal Professor of Biosystems Engineering and Design expressed his delight at this breakthrough by UL scientists.

“The €109-million Bernal Institute has the ambition to impact the world on the basis of top science in an increasingly international context. The impact of this discovery in the field of biological piezoelectricity will be huge and Bernal scientists are leading from the front the progress in this field,” he said.

Nanowire fingerprint technology

Apparently this technology from France’s Laboratoire d’électronique des technologies de l’information (CEA-Leti) will make fingerprinting more reliable. From a Sept. 5, 2017 news item on Nanowerk,

Leti today announced that the European R&D project known as PiezoMAT has developed a pressure-based fingerprint sensor that enables resolution more than twice as high as currently required by the U.S. Federal Bureau of Investigation (FBI).

The project’s proof of concept demonstrates that a matrix of interconnected piezoelectric zinc-oxide (ZnO) nanowires grown on silicon can reconstruct the smallest features of human fingerprints at 1,000 dots per inch (DPI).

“The pressure-based fingerprint sensor derived from the integration of piezo-electric ZnO nanowires grown on silicon opens the path to ultra-high resolution fingerprint sensors, which will be able to reach resolution much higher than 1,000 DPI,” said Antoine Viana, Leti’s project manager. “This technology holds promise for significant improvement in both security and identification applications.”

A Sept. 5, 2017 Leti press release, which originated the news item, delves further,

The eight-member project team of European companies, universities and research institutes fabricated a demonstrator embedding a silicon chip with 250 pixels, and its associated electronics for signal collection and post-processing. The chip was designed to demonstrate the concept and the major technological achievements, not the maximum potential nanowire integration density. Long-term development will pursue full electronics integration for optimal sensor resolution.

The project also provided valuable experience and know-how in several key areas, such as optimization of seed-layer processing, localized growth of well-oriented ZnO nanowires on silicon substrates, mathematical modeling of complex charge generation, and synthesis of new polymers for encapsulation. The research and deliverables of the project have been presented in scientific journals and at conferences, including Eurosensors 2016 in Budapest.

I have tended to take fingerprint technology for granted but last fall (2016) I stumbled on a report suggesting that forensic sciences, including fingerprinting, was perhaps not as conclusive as one might expect after watching fictional police procedural television programmes. My Sept. 23, 2016 posting features the US President’s Council of Advisors on Science and Technology (PCAST) released a report (‘Forensic Science in Criminal Courts: Ensuring Scientific Validity of Feature-Comparison Methods‘ 174 pp PDF).

Graphene and silly putty combined to create ultra sensitive sensors

One of my favourite kinds of science story is the one where scientists turn to a children’s toy for their research. In this case, it’s silly putty. Before launching into the science part of this story, here’s more about silly putty from its Wikipedia entry (Note: A ll links have been removed),

During World War II, Japan invaded rubber-producing countries as they expanded their sphere of influence in the Pacific Rim. Rubber was vital for the production of rafts, tires, vehicle and aircraft parts, gas masks, and boots. In the U.S., all rubber products were rationed; citizens were encouraged to make their rubber products last until the end of the war and to donate spare tires, boots, and coats. Meanwhile, the government funded research into synthetic rubber compounds to attempt to solve this shortage.[10]

Credit for the invention of Silly Putty is disputed[11] and has been attributed variously to Earl Warrick,[12] of the then newly formed Dow Corning; Harvey Chin; and James Wright, a Scottish-born inventor working for General Electric in New Haven, Connecticut.[13] Throughout his life, Warrick insisted that he and his colleague, Rob Roy McGregor, received the patent for Silly Putty before Wright did; but Crayola’s history of Silly Putty states that Wright first invented it in 1943.[10][14][15] Both researchers independently discovered that reacting boric acid with silicone oil would produce a gooey, bouncy material with several unique properties. The non-toxic putty would bounce when dropped, could stretch farther than regular rubber, would not go moldy, and had a very high melting temperature. However, the substance did not have all the properties needed to replace rubber.[1]

In 1949 toy store owner Ruth Fallgatter came across the putty. She contacted marketing consultant Peter C.L. Hodgson (1912-1976).[16] The two decided to market the bouncing putty by selling it in a clear case. Although it sold well, Fallgatter did not pursue it further. However, Hodgson saw its potential.[1][3]

Already US$12,000 in debt, Hodgson borrowed US$147 to buy a batch of the putty to pack 1 oz (28 g) portions into plastic eggs for US$1, calling it Silly Putty. Initially, sales were poor, but after a New Yorker article mentioned it, Hodgson sold over 250,000 eggs of silly putty in three days.[3] However, Hodgson was almost put out of business in 1951 by the Korean War. Silicone, the main ingredient in silly putty, was put on ration, harming his business. A year later the restriction on silicone was lifted and the production of Silly Putty resumed.[17][9] Initially, it was primarily targeted towards adults. However, by 1955 the majority of its customers were aged 6 to 12. In 1957, Hodgson produced the first televised commercial for Silly Putty, which aired during the Howdy Doody Show.[18]

In 1961 Silly Putty went worldwide, becoming a hit in the Soviet Union and Europe. In 1968 it was taken into lunar orbit by the Apollo 8 astronauts.[17]

Peter Hodgson died in 1976. A year later, Binney & Smith, the makers of Crayola products, acquired the rights to Silly Putty. As of 2005, annual Silly Putty sales exceeded six million eggs.[19]

Silly Putty was inducted into the National Toy Hall of Fame on May 28, 2001. [20]

I had no idea silly putty had its origins in World War II era research. At any rate, it’s made its way back to the research lab to be united with graphene according to a Dec. 8, 2016 news item  on Nanowerk,

Researchers in AMBER, the Science Foundation Ireland-funded materials science research centre, hosted in Trinity College Dublin, have used graphene to make the novelty children’s material silly putty® (polysilicone) conduct electricity, creating extremely sensitive sensors. This world first research, led by Professor Jonathan Coleman from TCD and in collaboration with Prof Robert Young of the University of Manchester, potentially offers exciting possibilities for applications in new, inexpensive devices and diagnostics in medicine and other sectors.

A Dec. 9, 2016 Trinity College Dublin press release (also on EurekAlert), which originated the news item, describes their ‘G-putty’ in more detail,

Prof Coleman, Investigator in AMBER and Trinity’s School of Physics along with postdoctoral researcher Conor Boland, discovered that the electrical resistance of putty infused with graphene (“G-putty”) was extremely sensitive to the slightest deformation or impact. They mounted the G-putty onto the chest and neck of human subjects and used it to measure breathing, pulse and even blood pressure. It showed unprecedented sensitivity as a sensor for strain and pressure, hundreds of times more sensitive than normal sensors. The G-putty also works as a very sensitive impact sensor, able to detect the footsteps of small spiders. It is believed that this material will find applications in a range of medical devices.

Prof Coleman said, “What we are excited about is the unexpected behaviour we found when we added graphene to the polymer, a cross-linked polysilicone. This material as well known as the children’s toy silly putty. It is different from familiar materials in that it flows like a viscous liquid when deformed slowly but bounces like an elastic solid when thrown against a surface. When we added the graphene to the silly putty, it caused it to conduct electricity, but in a very unusual way. The electrical resistance of the G-putty was very sensitive to deformation with the resistance increasing sharply on even the slightest strain or impact. Unusually, the resistance slowly returned close to its original value as the putty self-healed over time.”

He continued, “While a common application has been to add graphene to plastics in order to improve the electrical, mechanical, thermal or barrier properties, the resultant composites have generally performed as expected without any great surprises. The behaviour we found with G-putty has not been found in any other composite material. This unique discovery will open up major possibilities in sensor manufacturing worldwide.”

Dexter Johnson in a Dec. 14, 2016 posting on his Nanoclast blog (on the IEEE [Institute of Electrical and Electronics Engineers]) puts this research into context,

For all the talk and research that has gone into exploiting graphene’s pliant properties for use in wearable and flexible electronics, most of the polymer composites it has been mixed with to date have been on the hard and inflexible side.

It took a team of researchers in Ireland to combine graphene with the children’s toy Silly Putty to set the nanomaterial community ablaze with excitement. The combination makes a new composite that promises to make a super-sensitive strain sensor with potential medical diagnostic applications.

“Ablaze with excitement,” eh? As Dexter rarely slips into hyperbole, this must be a big deal.

Epic Scottish poetry and social network science

It’s been a while since I’ve run a social network story here and this research into a 250-year controversy piqued my interest anew. From an Oct. 20, 2016 Coventry University (UK) press release (also on EurekAlert) Note: A link has been removed,

The social networks behind one of the most famous literary controversies of all time have been uncovered using modern networks science.

Since James Macpherson published what he claimed were translations of ancient Scottish Gaelic poetry by a third-century bard named Ossian, scholars have questioned the authenticity of the works and whether they were misappropriated from Irish mythology or, as heralded at the time, authored by a Scottish equivalent to Homer.

Now, in a joint study by Coventry University, the National University of Ireland, Galway and the University of Oxford, published today in the journal Advances in Complex Systems, researchers have revealed the structures of the social networks underlying the Ossian’s works and their similarities to Irish mythology.

The researchers mapped the characters at the heart of the works and the relationships between them to compare the social networks found in the Scottish epics with classical Greek literature and Irish mythology.

The study revealed that the networks in the Scottish poems bore no resemblance to epics by Homer, but strongly resembled those in mythological stories from Ireland.

The Ossianic poems are considered to be some of the most important literary works ever to have emerged from Britain or Ireland, given their influence over the Romantic period in literature and the arts. Figures from Brahms to Wordsworth reacted enthusiastically; Napoleon took a copy on his military campaigns and US President Thomas Jefferson believed that Ossian was the greatest poet to have ever existed.

The poems launched the romantic portrayal of the Scottish Highlands which persists, in many forms, to the present day and inspired Romantic nationalism all across Europe.

Professor Ralph Kenna, a statistical physicist based at Coventry University, said:

By working together, it shows how science can open up new avenues of research in the humanities. The opposite also applies, as social structures discovered in Ossian inspire new questions in mathematics.”

Dr Justin Tonra, a digital humanities expert from the National University of Ireland, Galway said:

From a humanities point of view, while it cannot fully resolve the debate about Ossian, this scientific analysis does reveal an insightful statistical picture: close similarity to the Irish texts which Macpherson explicitly rejected, and distance from the Greek sources which he sought to emulate.”

A statistical physicist, eh? I find that specialty quite an unexpected addition to the team stretching my ideas about social networks in new directions.

Getting back to the research, the scientists have supplied this image to illustrate their work,

Bacteria and an anti-superbug coating from Ireland’s Sligo Institute of Technology

Unlike today’s (April 28, 2016) earlier piece about dealing with bacteria, the focus for this research is on superbugs and not the bacteria which form biofilm on medical implants and such. An April 21, 2016 news item on RTE News makes the announcement about a new means of dealing with superbugs,

A discovery by a team of scientists in Ireland could stem the spread of deadly superbugs predicted to kill millions of people worldwide over the coming decades.

The research has found an agent that can be baked into everyday items like smart-phones and door handles to combat the likes of MRSA and E. coli.

The nanotechnology has a 99.9 % kill rate of potentially lethal and drug-resistant bacteria, they say.

Lead scientist Professor Suresh C. Pillai, of Sligo Institute of Technology’s Nanotechnology Research Group, says the discovery is the culmination of 12 years work.

“This is a game changer,” he said.

“This breakthrough will change the whole fight against superbugs. It can effectively control the spread of bacteria.”

An April 21, 2016 Sligo Institute of Technology press release provides some context for the work and a few details about the coating,

News of the discovery comes just days after UK Chancellor of the Exchequer George Osborne warned that superbugs could become deadlier than cancer and are on course to kill 10 million people globally by 2050.

Speaking at the International Monetary Fund (IMF) in Washington, Mr Osborne warned that the problem would slash global GDP by around €100 trillion if it was not tackled.

Using nanotechnology, the discovery is an effective and practical antimicrobial solution — an agent that kills microorganisms or inhibits their growth — that can be used to protect a range of everyday items.

Items include anything made from glass, metallics and ceramics including computer or tablet screens, smartphones, ATMs, door handles, TVs, handrails, lifts, urinals, toilet seats, fridges, microwaves and ceramic floor or wall tiles.

It will be of particular use in hospitals and medical facilities which are losing the battle against the spread of killer superbugs.

Other common uses would include in swimming pools and public buildings, on glass in public buses and trains, sneeze guards protecting food in delis and restaurants as well as in clean rooms in the medical sector.

“It’s absolutely wonderful to finally be at this stage. This breakthrough will change the whole fight against superbugs. It can effectvely control the spread of bacteria,” said Prof. Pillai.

He continued: “Every single person has a sea of bacteria on their hands. The mobile phone is the most contaminated personal item that we can have. Bacteria grows on the phone and can live there for up to five months. As it is contaminated with proteins from saliva and from the hand, It’s fertile land for bacteria and has been shown to carry 30 times more bacteria than a toilet seat.”

The research started at Dublin Institute of Technology (DIT)’s CREST and involves scientists now based at IT Sligo, Dublin City University (DCU) and the University of Surrey. Major researchers included Dr Joanna Carroll and Dr Nigel S. Leyland.

It has been funded for the past eight years by John Browne, founder and CEO of Kastus Technologies Ltd, who is bringing the product to a global market. He was also supported by significant investment from Enterprise Ireland.

As there is nothing that will effectively kill antibiotic-resistant superbugs completely from the surface of items, scientists have been searching for a way to prevent the spread.

This has been in the form of building or ‘baking’ antimicrobial surfaces into products during the manufacturing process.

However, until now, all these materials were toxic or needed UV light in order to make them work. This meant they were not practical for indoor use and had limited commercial application.

“The challenge was the preparation of a solution that was activated by indoor light rather than UV light and we have now done that,” said Prof Pillai.

The new water-based solution can be sprayed onto any glass, ceramic or metallic surface during the production process, rendering the surface 99.9 per cent resistant to superbugs like MRSA, E. coli and other fungi. [emphasis mine]

The solution is sprayed on the product — such as a smartphone glass surface — and then ‘baked’ into it, forming a super-hard surface. The coating is transparent, permanent and scratch resistant and actually forms a harder surface than the original glass or ceramic material.

The team first developed the revolutionary material to work on ceramics and has spent the last five years adapting the formula – which is non-toxic and has no harmful bi-products ‑- to make it work on glass and metallic surfaces.

Research is now underway by the group on how to adapt the solution for use in plastics and paint, allowing even wider use of the protective material.

Prof Pillai, Kastus and the team have obtained a US and a UK patent on the unique process with a number of global patent applications pending. It is rare for such an academic scientific discovery to have such commercial viability.

“I was sold on this from the first moment I heard about it. It’s been a long road to here but it was such a compelling story that it was hard to walk away from so I had to see it through to the end,” said John Browne, Kastus CEO.

He continued: “This is a game changer. The uniqueness of antimicrobia surface treatment means that the applications for it in the real world are endless. The multinational glass manufacturers we are in negotiations with to sell the product to have been searching for years to come up with such a solution but have failed.”

If the coating kills 99.9%, doesn’t that mean 0.1% are immune? If that’s the case, won’t they reproduce and eventually establish themselves as a new kind of superbug?
