   life support system”

   Professor Lesley Hughes FRSN
   Dept. of Biological Sciences
   Macquarie University

Venue: Sydney Mechanics’ School of Arts, 280 Pitt Street, Sydney
Date and time: Thursday, 20 June 2019, 6pm – 7.30

Our climate system is changing rapidly as a result of the burning of fossil fuels. In Australia, we are already experiencing severe drought, increased bushfire and flooding risk, coastal erosion and unprecedented heatwaves. The changing climate is affecting all sectors – our economy, food security, health, and communities. But it is our environmental life support system that is feeling the impacts most significantly, with climate change exacerbating many other factors that lead to species loss and habitat decline.

Distinguished Professor Lesley Hughes joins us to summarise the latest global and national trends in the climate and identify the most important observed and future impacts, with an emphasis on biodiversity. She will also outline what we need to do to achieve a stable climate by the second half of this century, and how we need to change our approach to conservation.
But it’s not all bad news; we do have many exciting opportunities to ensure a viable future, both for the planet’s species and our children.

Presented jointly by the Royal Society of NSW and the Sydney Mechanics’ School of Arts, the Women and Science lecture series examines the huge changes we have seen in the roles women have played in science, and the view science has held of women.

The search for synthetic alternatives (including polymers) to scarce natural materials is not new, and substitution occurred well before today’s plastic bottles and packaging.  A reward of $10,000 for billiard balls, hitherto made from Sri Lankan elephant tusks, ultimately led to thermosets derived from cellulose.  Synthetic nylon stockings replaced unavailable silk (and made Du Pont wealthy) whilst synthetic rubber helped win the war.  The early history of polymer manufacture combines uneducated invention and entrepreneurship with debtor’s courts and skulduggery.  During the 20th century today’s ‘commodity’ polymers emerged, these being based on hydrocarbons including ethylene and propylene.  The public appetite for new synthetics that peaked in the 1950s and 60s (think of the movie The Graduate) has reversed despite polymer production showing unabated growth.  Scarcely a day now passes without reminders of waste, whether it is floating ‘continents’ or containers of Australian plastic being returned from overseas.  The solutions to today’s ‘polymer pollution’ need creative ideas and imaginative solutions but may provide lucrative opportunities.  Several possibilities will be discussed that may catalyse blue-sky input from the audience.

Emeritus Professor Robert Burford has made and broken plastics and rubber for over 40 years, first investigating cracking in nylons before research at the Australian Synthetic Rubber Company.  Since joining UNSW in 1978 he has interacted with the polymer industry at many levels.  He took students to draconian factories to motivate them beyond the factory floor, was a Co-op Program coordinator to attract top students to sometimes enter the same factories, and has been actively engaged in consulting, often examining polymer failures.  He was a lead researcher with the Cooperative Research Centre for Polymers, helping for example to develop a new family of fire performance cables.  He retired as Head of Chemical Engineering at UNSW in 2014 but still consults and volunteers at the Powerhouse Museum in conservation.

   
   “Nothing goes faster than light - usually!”

   Professor Lene Vestergaard Hau
   Harvard University

Date and time: Tuesday 23 July 2019, 6–8pm
Venue: Tyree Room, John Niland Scientia Building, UNSW Sydney
Cost: free
Reservations: here

This year’s lecture will explore how Lene and her team have slowed, stopped and restarted light. The observations represent the ultimate control over the inter-conversion of light and matter, and point to novel paradigms for quantum information processing.

“In our laboratory, we have used ultra-cold atom clouds to slow light pulses to the speed of a bicycle, which is 50 million times lower than the light speed in a vacuum.  In the process, a light pulse spatially compresses by the same large factor, from 1 km to only 0.02 mm, and the pulse can then be completely stopped and later restarted.

“From here, we have taken matters further: stopped and extinguished a light pulse in one part of space and revived it in a completely different location.  In the process, the light pulse is converted to a perfect matter copy that can be stored – put on the shelf – sculpted, and then turned back to light.  The storage time can be many seconds, and during this time light could – under normal circumstances – travel back and forth to the Moon several times over.”

The Dirac Medal for the Advancement of Theoretical Physics is awarded by UNSW in association with the Australian Institute of Physics NSW branch and The Royal Society of NSW.  The Lecture and the Medal commemorate the visit to UNSW in 1975 of the British Nobel laureate, Professor Paul Dirac.  Professor Dirac gave five lectures which were published as a book Directions of Physics.  He donated the royalties to UNSW for the establishment of the Dirac Lecture and Prize, which consists of a silver medal and honorarium. It was first awarded in 1979.

Nobel Laureate Elizabeth Blackburn delivers the inaugural Gerald Westheimer Lecture, chaired by UNSW Sydney’s Dean of Science, Professor Emma Johnston.

Why does ageing take such different paths for different individuals?  Why do some of us remain healthy and active into later life, while others age more rapidly?  Elizabeth Blackburn’s discoveries about telomeres, the protective caps at the end of our chromosomes, have transformed the way we think about these important questions and earned her a Nobel Prize in 2009.  Although we have long understood the impact of our genetic inheritance on our health, Blackburn’s work has shown us the key role that telomeres and the enzyme telomerase play in the ageing process.

Be part of a special event with Elizabeth Blackburn as she discusses her work in this fascinating space and its implications for the future of ageing.

This talk is part of the Sydney Science Festival, and is supported by the Crawford Fund and Science & Technology Australia.

Gerald Westheimer Lectureship

The Gerald Westheimer Lecture is a new biennial lecture series for UNSW Science thanks to a generous gift from Professor Gerald Westheimer AM FRS.  This flagship initiative will invite eminent international researchers to spend time in residence at the University.

Elizabeth Blackburn

Dr Elizabeth Blackburn has been a leader in the area of telomere and telomerase research, having discovered the molecular nature of telomeres – the ends of eukaryotic chromosomes that serve as protective caps essential for preserving the genetic information – and co-discovered the ribonucleoprotein enzyme, telomerase.  She is also known for her championing of diversity and inclusion in the sciences.  Blackburn and her research team also collaborate in a range of investigations of the roles of telomere biology in human health and diseases, through clinical and other human studies.  Born in Australia, Dr Blackburn earned degrees from the University of Melbourne, University of Cambridge and Yale University.  She has been awarded the Nobel Prize in Physiology or Medicine, the Albert Lasker Medical Research Award for Basic Medical Research, and in 2007 was named one of TIME magazine’s 100 Most Influential People.

   “This talk may cause side effects: 
     nocebo effects in medicine”

   Dr Kate Faasse
   School of Psychology
   UNSW

Wednesday 5 June 2019
Gallery Room, State Library of NSW

Almost everyone has experienced unpleasant side effects from a medical treatment. But what if I were to tell you that most of these side effects aren’t caused by the treatment itself, but by a powerful psychobiological phenomenon called the nocebo effect? The nocebo effect is sometimes seen as the ‘dark side’ of the better-known placebo effect where healing or health improvements are triggered by the treatment context rather than any therapeutic effects of the treatment itself. In contrast, nocebo effects are the unpleasant or adverse outcomes that can be triggered by the treatment context, including information about possible side effects, seeing or reading about someone else experience unpleasant side effects, and generic versus brand name labelling of the medication. This talk used case studies to illustrate the potential impact of nocebo effects in daily life, and discussed recent evidence on the development of nocebo effects, the different treatment context factors that can increase the experience of nocebo effects, the implications of nocebo effects for patients and public health, and evidence on strategies that might help to reduce nocebo effects.

Kate Faasse is an ARC DECRA Fellow and Senior Lecturer in Health Psychology in the School of Psychology at the University of New South Wales. Originally from New Zealand, Kate completed her Bachelors, Masters, and PhD training in Psychology at the University of Auckland, specializing in Health Psychology. She moved to Sydney to take up a Lecturer position in the School of Psychology at UNSW in 2016. During this time Kate has produced over 35 publication and has received over $1million in competitive funding from sources such as the ARC (Australia), and the Auckland Medical Research Foundation (New Zealand). Highlighting the importance of her research into the nocebo effect, Kate’s work was also supported by the Pharmaceutical Management Agency of New Zealand (PHARMAC), and her research has informed healthcare policy in New Zealand. Kate’s research in Health Psychology focuses on aspects of medication use, including nocebo and placebo effects, treatment adherence, and perceptions of generic medicines. Ultimately, she hopes that her research will contribute to reducing the burden of nocebo-induced medication side effects in Australia through generating greater understanding of factors that influence the formation and maintenance of nocebo effects, and the development of interventions to reduce nocebo effects in clinical practice.

   “Ada Lovelace, without whom
   we might not have computers”

   Susannah Fullerton OAM FRSN

Thursday 2 May 2019
Sydney Mechanics’ School of Arts, 280 Pitt Street, Sydney

The only child of the poet Lord Byron and his wife Annabella who adored mathematics, Ada, Countess of Lovelace, worked with Charles Babbage on his ‘analytical engine’. It was Ada who first recognised the future possibilities of the machine, and who made notes which can be considered the first computer programme. Babbage focussed on what his machine could do with numbers, but Ada saw its potential beyond numbers and anticipated the implications of the computer a hundred years before anyone else. Her view was that if you had a machine that manipulated numbers, then the numbers could represent other things — letters, music, symbols — and so could move beyond calculation to computation. Susannah Fullerton presents an illustrated lecture on the short life and far-reaching achievements of this remarkable woman.

Susannah Fullerton is Sydney’s best-known literary lecturer, giving talks on famous authors, their lives and works. She has spoken at literary conferences around the world, and is regularly sought as an entertaining and informative speaker at fund-raising events, conference dinners, schools, libraries, universities, bookshops and clubs. She is a registered speaker for ADFAS (The Australian Decorative and Fine Arts Societies) and travels Australia giving presentations to the groups. She is interviewed regularly on ABC radio and has often been interviewed for TV. She presents regular series at the Art Gallery of NSW and the State Library of New South Wales.

See the calendar of 2019 events for details of further talks in this series.

   “Measuring what we can:
   or how to lose weight on May 20th”

   Emeritus Professor Brynn Hibbert
   School of Analytical Chemistry
   UNSW

Wednesday 3 April 2019
Gallery Room, State Library of NSW

Galileo said “Measure what is measurable, and make measurable what is not so”, which is a statement of how important measurement is, not just to science, but living as a human.  I have spent much of my career measuring things in chemistry, and have become fascinated by why, what and how we measure.  Whether it was the length of a Pharoh’s forearm in 3000 BCE, or a ten-millionth of half a meridian in 1795, we have attempted to understand our world by first measuring it: its extent (length, area and volume), how much of it there is (mass, amount of substance), and duration (time).  Modern phenomena of electricity, forms of energy, temperature and the brightness of light, have all been wrestled into submission by the metrologists.
I raise this now, because on 20 May 2019, World Metrology Day, we will witness a new turn of the metrological wheel, as the dear old kilogramme in Paris is retired in favour of a quantum mechanical definition in which the numerical value of the Planck constant is fixed.  There will be other changes and in my talk I shall tell you whether we will all weigh any different at 00:01 on 20 May than we did at 23:59 on 19 May.

Brynn Hibbert occupied the Chair of Analytical Chemistry at the University of New South Wales since arriving from England in 1987 until his retirement in 2013.  His research interests are in metrology and statistics in chemistry, ionic liquids and electroanalytical chemistry, but he also does a sideline in expert opinion, scientific fraud and presenting science to the public.  Long a member of the International Union of Pure and Applied Chemistry, he has helped name elements, revise the SI units and write the terminology of chemistry.  More recently he has become a go-to expert witness in matters of drugs (of abuse, and sports).  He is the immediate past President of the Royal Society of New South Wales, and was made a member of the Order of Australia in 2018.

The Women and Science lecture series is co-hosted by the Royal Society of NSW and the Sydney Mechanics’ School of Arts. It examines the huge changes in the roles women play in science, and the view science has of women. Prohibited for much of history from having a serious interest in such a ‘masculine’ domain, women now abound in science, mathematics and engineering. How did that come to be? How did interaction with the visual and literary arts so often assist women in their scientific endeavours? What fascinating discoveries have women made that have changed our world and our understanding of it?

   “Mary Shelley, scientist,
    and Frankenstein”

Thursday 21 March 2019
Sydney Mechanics’ School of Arts, 280 Pitt St, Sydney

Suzanne Burdon discussed the remarkable achievements of Mary Shelley, who, as a feisty 18-year-old, read every important scientific treatise and created Frankenstein and his monster in a moral tale that still highlights the exact scientific ethical dilemmas we face today (for example, the cloning of real human babies).

Mechanisms by which the Royal Society of NSW can collaborate with the University of Newcastle for the benefit of the Newcastle region

Thursday 7 March 2019, 4-6 pm
Hunter Medical Research Institute, New Lambton Heights

The purpose of the meeting was to explore possible collaboration between the Royal Society of NSW and the University of Newcastle in establishing a presence for the Society in Newcastle for the benefit of both organisations and for the Newcastle community as a whole.

The meeting was hosted by the University of Newcastle at the Hunter Medical Research Institute, with the Chancellor, Vice-Chancellor and several Pro Vice-Chancellors of the University present. It was followed by a dinner at the Newcastle Club at 40 Newcomen Street.

    “Using genomics to conserve
     Australia’s biodiversity”

    Katherine Belov
    School of Life and Environmental Sciences
    University of Sydney

There was also a 3-minute thesis (3MT) talk: “Pee-cycling: transforming our urine into valuable fertiliser” by Federico Volpin, University of Technology Sydney.

Wednesday 6 March 2019
Gallery Room, State Library of NSW

In recent years innovations in genomic technologies and the drop in the cost of sequencing has made it feasible to apply conservation genomics techniques to conservation of threatened species. The speaker discussed how we have used genomics data to make informed management decisions for the conservation of two iconic Australian marsupials, the Tasmanian devil and the koala.

The Tasmanian devil, Australia’s largest remaining marsupial carnivore, faces extinction in the wild due to the emergence of a new infectious disease. Devil Facial Tumour Disease (DFTD) is a contagious cancer that is spread as an allograft by biting. The tumour spreads due to low levels of genetic diversity in devil populations plus its capacity to evade the immune system. The disease continues to decimate Tasmanian devil populations, with over 85% of the species already lost. Interestingly, although predicted, extinction has not yet occurred. The speaker discussed the use of genomics and transcriptomics to help us to understand the disease, its evolutionary trajectory and the role of genomics in the quest to save the species from extinction in the wild.

The koala is an iconic Australian animal, famous for their ability to sleep up to 22 hours a day high in eucalyptus trees and subsist on a diet of toxic eucalyptus leaves. Joeys are born after a short pregnancy of only 35 days. Sadly the species is threatened due to heavy exploitation for their pelt, followed by habitat clearing and fragmentation of populations. They also have a chequered history of population management, with extensive translocations resulting in population bottlenecks in southern populations. Significant localised extinctions of koalas are occurring, particularly in South-East QLD and Northern NSW. Recent modelling has shown that the best way to stabilise heavily affected koala populations is to target disease. The speaker discussed the use of genomics data to help understand and manage koala populations through greater understanding of disease, immunity and koala biology, including immunological protection in the pouch and eucalyptus detoxification.

Beyond devil and koala, the speaker talked about the Earth Biogenome project, an ambitious project that aims to sequence the genomes of all eukaryotic life on earth and our role in sequencing the genomes of 50 of Australia’s most endangered species with the specific purpose of providing genetic management advice to conservation agencies.

Professor Kathy Belov is a Professor of Comparative Genomics in the School of Life and Environmental Sciences in the Faculty of Science at the University of Sydney. Kathy’s research expertise is in the area of comparative genomics and immunogenetics of Australian wildlife, including Tasmanian devils and koalas, two iconic species that are threatened by disease processes. Her research team has participated in the koala, opossum, platypus and wallaby genome projects where they have gained insights into genes involved in immunity and defense, including platypus venom genes and novel antimicrobial peptides in the pouch. Kathy has published over 150 peer-reviewed papers, including papers in Nature, Proceedings of the National Academy of Science and PLoS Biology. She has received two Eureka awards, the Crozier medal and the Fenner medal from the Australian Academy of Science for her research. She is currently the immediate past president of the Genetics Society of Australasia and a Fellow of the Royal Society of NSW. Kathy is also the Pro-Vice Chancellor (Global Engagement) at the University of Sydney. In this position she takes responsibility for managing the development and execution of the University’s global engagement strategy. Key priorities are the development of the capacity of academic and professional staff to support international student learning and international research collaborations, and to achieve educational excellence in the international arena. She also promotes the University’s position in the international academic and research community, and identifies and enables strategic opportunities for partnership and collaboration in research and education.

The Speaking of Music lecture series is co-hosted by the Royal Society of NSW and the Sydney Mechanics’ School of Arts. Our speakers will examine music, its relation to the world and its profound power to affect us – sometimes in surprising ways.

   

    “Jazz and democracy”

   Dr. Wesley J. Watkins IV
   Jazz and Democracy Project

Tuesday 26 February 2019
Thomas Keneally Centre, Level 3, Sydney Mechanics’ School of Arts

Dr Watkins is founder of the Jazz and Democracy Project, a music integrated curriculum that utilizes jazz as a metaphor to bring American democracy to life, enrich the study and teaching of U.S. history, government, civics and culture, and inspire youth to become active, positive contributors to their communities.

“Dr. Wes,” as his students call him, first proposed such a curriculum as part of the Stanford University School of Education Undergraduate Honors Program. He conducted research for his undergraduate honors thesis at Oxford University where he engaged and learned from music educators at both local elementary schools and world-renowned secondary institutions like The Bedales School, Eaton College, and The Yehudi Menuhin School.

After earning his PhD from the International Centre for Research in Music Education at the University of Reading, England, Dr. Wes immediately applied his knowledge as an independent arts education consultant in the San Francisco Bay Area, working at the district, school, and classroom levels. He then spent three years working for education-reform non-profits where he facilitated professional development for teachers, instructional coaches and administrators.

Dr. Wes is an avid music lover—particularly jazz and Afro-Cuban jazz—who loves to witness artists standing emotionally naked, transmitting their emotions to the audience, and modeling the best of what improvised music has to offer: a lesson in unity. Now living in Sydney, Dr Wes is speculating on how these principles might apply to Australian democracy and Australian education.

   “Legal considerations pertaining to
    nuclear energy as an option for Australia”

   Helen Cook
   GNE Advisory

Monday 25 February 2019
Allens, Level 28, Deutsche Bank Place, 126 Phillip Street, Sydney

This presentation gave an overview of international approaches to the development of nuclear power programmes in emerging nuclear countries, and discussed legal considerations for Australia should Australia wish to develop a domestic nuclear power programme. The speaker drew on her experience advising on nuclear projects and transactions in the United Kingdom, the United States, Egypt, Turkey, the United Arab Emirates, Argentina, India, Bahrain, Saudi Arabia and South Africa, as well as her cooperation with the International Atomic Energy Agency. 

Helen Cook from GNE Advisory is an independent nuclear energy lawyer dedicated to all aspects of the civil nuclear sector. She is the author of the comprehensive legal text book, The Law of Nuclear Energy published by Sweet & Maxwell, (2nd edition, March 2018), recently reviewed in the International Energy Law Journal by Tim Stone CBE. She is the former chairperson of the Law Working Group of the World Nuclear Association. Helen obtained her law degree from the University of Sydney and commenced her career at Allens Arthur Robinson.

“Human-associated bacteria and antibiotic resistance in grey-headed flying foxes”

Over recent decades, the number of grey-headed flying foxes (also known as fruit bats) roosting in urban environments has increased dramatically. Each year, several thousand sick, injured and orphaned flying foxes enter wildlife rehabilitation facilities. In urban areas and rehabilitation facilities, flying foxes encounter human-associated bacteria which may be pathogenic. At present, the transmission of human-associated organisms between humans and flying foxes is poorly understood. Additionally, antibiotic-resistant bacteria are spreading from humans to wildlife; currently there is a paucity of surveillance data on the spread of antibiotic resistance into Australian wildlife, including flying foxes.
This research examining the spread of human-associated bacteria (escherichia coli and klebsiella pneumoniae) to flying foxes is providing insight into the unique diversity and ecology of these bacteria in the grey-headed flying fox (pteropus poliocephalus). Flying foxes have also acquired antibiotic-resistant bacteria, including multidrug-resistant escherichia coli, in both urban and rehabilitation settings. The prevalence of genetic determinants of antibiotic resistance is higher in flying foxes in rehabilitation facilities than in wild urban flying foxes. We are yet to understand the implications of these findings on the management and conservation of the endangered grey-headed flying fox.

Fiona McDougall obtained a Bachelor of Veterinary Science from the University of Sydney in 1998 and subsequently spent over ten years working as a veterinarian and conducting biomedical and wildlife research. In 2013 she obtained a Master of Veterinary Studies in conservation medicine from Murdoch University. She is currently in the third year of her PhD at Macquarie University. In 2017 she was awarded a Holsworth Wildlife Research Endowment grant, and she is also a co-investigator on a Lake Macquarie Environmental Trust grant (2017).

“Using genetics to improve athletic performance in thoroughbred horses”

Thoroughbred horse racing holds both historical and economic significance in Australian society, dating back to the early colonial years of settlement. The thoroughbred racing and breeding industry is also a major contributor to the Australian economy due to the internationally recognised quality of the horses it produces.
The thoroughbred horse breed was founded in the 18th century, making it the oldest closed animal population in the world. Uniquely, all modern thoroughbred horses throughout the world trace their pedigree back to this time (an average of 24 generations). Although thoroughbreds are the product of many generations of inbreeding for the selection of racing performance, the population is still viable and thriving. Evelyn's research examines how these many generations of selective breeding has influenced the genetic characteristics of modern thoroughbred horses. These findings assist in understanding the effects of long-term selection on the health and viability of animal populations.

Evelyn Todd is a PhD student at University of Sydney, researching and writing a thesis titled “Inbreeding and performance genetics in horses”. She started her PhD candidature at the beginning of 2017, having completed a Bachelor of Science (Honours) in 2015. Her self-directed honours thesis focussed on the effects of inbreeding on racing performance in thoroughbred horses. After completing her undergraduate degree, she spent a year working in industry before returning to postgraduate study. Her PhD aims to understand genetic trends in horse populations, particularly focussing on thoroughbred racehorses.

Three-minute thesis (3MT) talk
The Three-Minute Thesis (3MT) competition brings together some of the best and brightest PhD students, who have just three minutes to explain what they are doing, how they are doing it, and why it is important. The competition cultivates students’ academic, presentation, and research communication skills, and their capacity to communicate complex ideas to a non-specialist audience. Competitors are allowed one PowerPoint slide, but no other resources or props.

This month’s presentation, “Finding the best-fitting jeans for railway foundations”, was by Mr Chuhao Liu, Faculty of Engineering and Information Sciences, University of Wollongong, winner of the University of Wollongong 2018 3MT competition.

Train is a very popular choice for travelling and freight transport in Australia. However, track foundation particles (ballast) are almost free to move laterally and subjected to significant breakage upon repeated train passage. To solve this problem, industry currently installs a plastic grid, named Geogrid, inside the railway foundations. But the best design of geogrid remains an open question. The research aims to find out the optimum design of geogrid, especially the size of the hole (aperture) on the grid, and develop a standard for rail manufacturing.

Jak Kelly Award lecture and Christmas party

“Hydroxyl as a probe of the molecular interstellar medium”

  Anita Petzler, Jak Kelly Award winner for 2018

  Department of Physics and Astronomy
  Macquarie University

Wednesday 5 December 2018
State Library of NSW, Sydney

The Jak Kelly Award
This award was created in honour of Professor Jak Kelly (1928 - 2012), who was Head of Physics at University of NSW from 1985 to 1989, was made an Honorary Professor of University of Sydney in 2004, and was President of the Royal Society of NSW in 2005 and 2006.  Its purpose is to encourage excellence in postgraduate research in Physics.
The winner was selected from a short list of candidates who made presentations at a recent joint meeting of the Australian Institute of Physics NSW Branch, the Royal Australian Chemical Institute and the Royal Society of NSW, which was held at UNSW.

Abstract
The interstellar medium is the collection of gas and dust between the stars of a galaxy and is the raw material from which new stars are formed. Its physical properties as well as a complex set of internal and external influences determine the mass distribution of stars formed. By observing the interstellar medium, we can begin to unravel these complex interactions and build robust models of star formation in galaxies. The interstellar medium consists of atomic gas traced by 1420 MHz hydrogen emission, and molecular gas traditionally traced by 115 GHz carbon monoxide emission.
My research recognises the limitations of carbon monoxide as a tracer of more diffuse molecular gas and employs an alternate tracer: hydroxyl. Hydroxyl is expected to coexist with molecular hydrogen in all environments, including those not well traced by carbon monoxide. The ground state of hydroxyl is split into four levels due to lambda doubling and hyperfine splitting. There are four allowable transitions between those levels at 1612, 1665, 1667 and 1720 MHz. The relative population of hydroxyl molecules in each level is determined by the local gas conditions which in turn determines the relative intensity of absorption or emission. I measure the emission and absorption in the transitions of hydroxyl along sightlines towards bright background continuum sources to determine the local conditions of the intervening hydroxyl gas. Modern observation techniques including large-scale surveys using telescopes with unprecedented resolution such as the Square Kilometre Array will give us an overwhelming wealth of data. Therefore, I am developing an automated analysis pipeline that will allow us to quickly extract our target parameters from these observations in a physically and statistically rigorous way. My work will allow us to take full advantage of these remarkable new facilities to complete our understanding of the mechanisms of star formation.

Biography
After growing up in Southern California, Anita Petzler moved to Australia at the age of 18 to complete a Bachelor of Science in Physics and Astrophysics at Monash University in Melbourne. This was followed by a Graduate Diploma of Education, an 8-year career as a High School Physics and Science teacher, and a move to Sydney. She returned to her studies in 2013, completing Honours at UNSW with a project on molecular clouds of the interstellar medium, supervised by Dr Maria Cunningham. Her interest in this field continued with a Masters by Research at Macquarie University supervised by Dr Joanne Dawson. She then began a PhD in July of this year under the supervision of Dr Joanne Dawson and Dr Mark Wardle.
“Ever since the age of 5, when my kindergarten teacher introduced me to the science of space, I've known that I wanted to be an astronomer. It's been a long journey, but the completion of my PhD will represent the realisation of the dreams of that little 5-year-old girl. Thank you for the opportunity to share my enthusiasm and interest in this grand field with such a distinguished group of like-minded scientists.”

“Towards a prosperous and sustainable Australia: what now for the lucky country?”

Hosted by His Excellency General The Honourable David Hurley AC DSC (ret’d.), Governor of NSW and Patron of the Royal Society of NSW

Thursday 29 November 2018
Government House, Sydney

A day dissecting the big questions facing Australia today and into the future. Australia’s 27 years of uninterrupted growth, the longest period without a recession of any developed country, puts it in an enviable position. Yet polling of the Australian population shows a large diversity of opinion on whether people feel better off. Rising wealth inequality, unaffordable housing, increasing traffic congestion, under-employment and increasingly polarised political opinion are hardly signs of a prosperous and harmonious society. Our environment is also suffering – loss of biodiversity, wildlife habitat and topsoil through land clearing and land-use change; the health and resilience of our river systems, forests and agricultural industries are subject to an inexorably warming climate and greater weather extremes.

Is the focus on growth and GDP pushing Australia in the wrong direction? Does Australia have an optimal population? What happens when we stop borrowing from future generations to support our current lifestyles and incessant consumption? Is a steady-state society possible, or desirable, and if so what would it look like?

The 2018 Royal Society of NSW and Four Academies Forum will examine the implications of the focus on growth (as measured by GDP) and population on our society, our economy and the environment. What are the social constructs and economic assumptions on which government policies are based? Our economy has become bifurcated towards resources and services – is this a healthy evolution or is it a hollowing-out of the economy that imperils Australia’s future? What role can science and technology play in a world of increasing automation and computer power? Is full employment possible, or desirable, and what will people do with their spare time?

The programme for the day is available here.

The day concluded with a drinks reception.

   
   Lecture 4

   “A geologist, geographer and anthropologist”

    Professor Alison Bashford FRSN
    School of Humanities & Languages
    UNSW

Monday 12 November 2018
Mitchell Theatre, Sydney Mechanics’ School of Arts, 280 Pitt St, Sydney

This is the final in a series of four talks co-hosted by the SMSA and the Royal Society of NSW on the topic “Great Australians You’ve Never Heard Of”.  Our speakers reveal the stories of remarkable Australians who have not received the recognition they deserve.

Our final Great Australian was a geologist, geographer, and anthropologist.  His travels took him from Scott’s final expedition in Antarctica to every continent on Earth, in a life that stretched from the South African War to the Cold War.  Highly controversial in 1920s Australia, he relocated to the University of Toronto, pursuing a stellar career.  Yet this Great Australian has been both acclaimed and derided as one of the twentieth century’s most insistent environmental determinists.  Join Alison Bashford to learn this Great Australian’s identity and to hear about his remarkable life.

Alison Bashford is Research Professor in History.  Her work connects the history of science, global history, and environmental history into new assessments of the modern world, from the eighteenth to the twentieth centuries.  She has recently focused on the geopolitics of world population, presented in two books: The New Worlds of Thomas Robert Malthus: Re-reading the Principle of Population, with Joyce E. Chaplin (Princeton University Press, 2016) and Global Population: History, Geopolitics and Life on Earth (Columbia University Press, 2014).  Before taking up her Research Chair at UNSW, Alison Bashford was the Vere Harmsworth Professor of Imperial and Naval History at the University of Cambridge, Fellow of Jesus College, Cambridge, and Trustee of Royal Museums, Greenwich, UK.  In 2009-10, she was the Whitlam and Fraser Chair of Australian Studies at Harvard University’s Department of the History of Science.  She has researched and taught at the University of Sydney and the Australian National University.  Alison Bashford is a Fellow of the British Academy and of the Australian Academy of Humanities.  In May 2018, she presented the Wiles Lectures at Queen’s University, Belfast.

   “Breakthrough! The detection of gravitational
    waves from a neutron star merger”

   Associate Professor Tara Murphy
   School of Physics
   The University of Sydney

There was also a 3-minute thesis talk, “Bio-Nano Robo-Mofos”, by Mr Jonathan Berengut, UNSW 2018 3MT winner.

Wednesday 7 November 2018
Gallery Room, State Library of NSW

On August 17th 2017 the LIGO-Virgo interferometer detected gravitational waves from a neutron star merger in a galaxy 130 million light years away. This was a breakthrough for physics and astronomy. What followed was a frenzy of activity as astronomers around the world worked to detect electromagnetic radiation with conventional telescopes. After this unprecedented effort the event was detected in gamma-rays, x-rays, visible light and radio waves. Professor Murphy described this incredible scientific result and its implications, including predictions made by Einstein, the production of gold and other heavy elements, and our understanding of black hole formation. She also gave a ‘behind the scenes’ perspective of how it happened, and discussed the changes in the way we do science in this era of big astronomy.

Associate Professor Tara Murphy is an astrophysicist working at the University of Sydney and an Australian Research Council Future Fellow. She has a Bachelor of Science from the University of Sydney and a PhD in astrophysics from the University of Edinburgh.  Tara leads an international team of researchers trying to detect and study transient and highly variable astrophysical phenomena with the MWA and ASKAP radio telescopes in Western Australia. In 2017 her team detected the first radio emission from a gravitational wave event caused by the merger of two neutron stars. Tara is also passionate about teaching and public outreach. In 2014 she co-founded a start-up company, Grok Learning, to get high school students around the world excited about computational thinking.

Three Minute Thesis (3MT) competition

The Three Minute Thesis (3MT) competition brings together some of the best and brightest PhD students, who have just three minutes to explain what they are doing, how they are doing it, and why it is important. The competition cultivates students’ academic, presentation, and research communication skills, and their capacity to communicate complex ideas to a non-specialist audience. Competitors are allowed one PowerPoint slide, but no other resources or props.

This month’s presentation was by Mr Jonathan Berengut, winner of the UNSW 2018 3MT competition. In the field of bionanotechnology, complex, precise nanoscale structures are assembled from biological molecules like DNA. It is even possible to build flexible, modular ‘nanobots’ capable of relatively simple tasks like targeted drug delivery and biosensing. To increase the scale and complexity of the tasks that these nanobots can perform, it is necessary to program them to assemble into larger formations. Jonathan’s research centres around the design and synthesis of DNA-nanobots that assemble into specific formations such as rows of fixed length. This research furthers our control of matter at the nanoscale and thus may lead to novel nanomaterials, nanoelectronics and nanomedicines.

   “3D printing of body parts: practical applications
   and fundamental explorations” 

   Professor Gordon Wallace AO FRSN
   Director, Intelligent Polymer Research Institute
   University of Wollongong

There was also a 3-minute thesis talk, “Knowing your alien”, by Mr Yingyod Lapwong, Faculty of Science, University of Technology Sydney.

Wednesday 3 October 2018
Gallery Room, State Library of NSW

In recent times we have witnessed medical breakthroughs enabled by advances in cell therapies, biomaterials science and 3D printing. The convergence of these three areas has enabled rapid progress. We have seen this impact on customised wearable prosthetics as well as implantable components (such as 3D metal printed jaw or heel implants) that provide structural support. The ability to replicate not just 3D shapes but also the distribution of mechanical properties from medical imaging data is being used to create models to understand airway collapse and to develop innovative intervention strategies in sleep apnoea. Polymer-based 3D printed structures have been used to provide scaffolds that facilitate tissue regeneration through strategic distribution of bioactive molecules including drugs and growth factors.

Perhaps the ultimate regenerative platform is a 3D printed structure that contains stem cells configured in an appropriate chemical and mechanical environment to induce appropriate tissue regeneration. This ability to create 3D structures containing living cells is impacting on diverse clinical challenges. These include cartilage regeneration using adipose stem cells and corneal regeneration using limbal stem cells. Professor Wallace’s research team is developing 3D printing protocols to allow for more effective transplantation of islet cells to treat Type 1 Diabetes. These new approaches to the assembly of cells within 3D structures are also enabling unprecedented fundamental explanations in the development of stem cells.

His research team is particularly interested in the development into neural lineages. Their quest to create a ‘brain on a bench’ is expected to enable us to better understand the development of illnesses such as epilepsy and schizophrenia and to devise more innovative interventions. Professor Wallace reported on their most recent studies on printing stem cells and the impact of the printed environment on stem cell development, also touching on some non-technical challenges arising in this rapidly developing area of medical research: ethical and regulatory issues.

Professor Wallace is Executive Research Director of the Australian Research Council Centre of Excellence for Electromaterials Science and Director of the Australian National Fabrication Facility, Materials Node at the University of Wollongong. His research focuses on the design and discovery of new materials for use in energy and health. In the health area this involves using new materials to develop biocommunications from the molecular to skeletal domains in order to improve human performance. In the energy area this involves use of new materials to transform and to store energy, including novel wearable and implantable energy systems for the use in medical technologies.

Professor Wallace was named NSW Scientist of the Year 2017 and was appointed as an Officer of the Order of Australia in 2017. He received the Eureka Prize for Leadership in Science and Innovation in 2016 and was appointed to the Prime Minister’s Knowledge Nation 100 in 2015.

He has published more than 900 refereed publications that have attracted in excess of 35,000 citations, plus a monograph on Organic Bionics (published 2012), and he recently co-authored an eBook on 3D BioPrinting. He led the presentation of a MOOC on 3D Bioprinting on the FutureLearn platform (www.futurelearn.com/courses/bioprinting).

Mr Yingyod Lapwong, a PhD student from University of Technology Sydney, gave a 3MT on his research: “Know your alien”. It focuses on alien species, which are an important environmental problem in Australia. Every year, the government spends a lot of money and effort to try to control these unwanted species. His research is about better understanding such species in order to develop better management systems to control them.
