Dr Elspeth MacRae, General Manager Manufacturing & Bloproducts, Scion
People have been improving plants and animals for many centuries. Most of the foods we eat and drink have been changed (domesticated) by humans. For many centuries this was done by selecting naturally occurring changes (or mutations) and using them to breed improved plants or animals – a very slow process. More recently we have been able to use biotechnology to make the same sort of changes in a much faster and more predictable way.
This talk will describe these Genetic Modification technologies, including the recent developments in gene editing (CRISPR-cas9). Examples of improved products will be highlighted, and the potential of gene editing to revolutionise food production will be discussed.
Dr Elspeth MacRae is the General Manager Manufacturing & Bioproducts at Scion in Rotorua. She is a member of the management group for the 2014 New Zealand National Science Challenge in Science and Technology for Industry, and leads the design, materials and manufacturing portfolio.
Scion is a Crown Research Institute that specialises in research, science and technology development for the forestry, wood product, wood-derived materials, and other biomaterial sectors.

2017 Hochstetter Lecture
The landscape of New Zealand is spectacular in its expression of the active tectonic processes that occur along the Pacific-Australian plate boundary. However, it is difficult to determine the geological history of development of the onshore topography because previous configurations in the evolution of that topography have been eroded.
Some of the native fauna carry a biological memory of the topographic environments in which they evolved, in their genetic makeup (DNA). Native freshwater fish are the most useful for this type of study. In particular, the genus Galaxias has numerous freshwater-limited species and populations that have been isolated by changes in the river drainage pattern.
The South Island vividly displays the resultant biological diversity and co-evolution of topography and fish. The genetic variations of the fish can be used to document the nature and timing of river capture events and mountain range growth, especially since the Plio-Pleistocene but with some extensions into the Miocene. Hence, these biological tools provide some new insights into the development of the onshore landscape since the submergence or near- submergence of the NZ landmass in the Oligocene. The biological memory approach to understanding topographic evolution could be extended to all endemic NZ fauna and flora for which suitable distribution and genetic data are available.
Dave Craw is Professor of Economic Geology at the University of Otago where he has been on staff for 35 years. His main research interests are gold: exploration, mining and associated environmental issues, both placer and hard-rock. His particular interests in tectonic evolution of mountains and the gold within them led him to work on the biological effects of the rise of mountain ranges, the topic of the Hochstetter lecture.
In August 2017, the Branch hosted a lecture by three nanoscientists from the MacDiarmid Institute, two of whom were available to visit a school in the afternoon before their lecture. Dr Catherine Whitby, a Senior Lecturer in Chemistry at Massey University, spoke to Year 11 and 13 students at Karamu High. Dr Gemma Cotton, a post-doctoral researcher at the University of Otago, spoke to Year 9 and 10 students at Napier Girls High. They outlined what inspired them to be a scientist, what influenced their journey through university, how they chose their area of expertise, the research they are currently doing and its potential benefits. One of the teachers commented: “I think one of the greatest benefits to students is it brings real science to life for them.” Several teachers and students also attended the evening lecture at the National Aquarium, where the audience exceeded 60.

Date: 6.00pm Thursday 31 August 2017
Venue: Lecture Theatre 1, EIT, Gloucester Street, Taradale
Admission: Gold coin donation
Earth’s ‘critical zone’ is everything from the treetops to the bottom of aquifers. This zone provides water for human consumption and food production.
Human impacts and climate change affect water in the critical zone. The deep parts of the critical zone are hard to study.
Dr Singha explores some of these critical zone unknowns in this presentation, shedding light on key underground processes that affect water movement and availability. The links between evapotranspiration and underground water stores are examined, as well as 3D water movement over large areas, and the potential control of slope aspect on underground permeability.
The role of trees in the critical zone, and their connection to soil moisture, groundwater and stream flow, is explored through innovative imaging.
Dr Kamini Singha is on a 12 lecture tour of Australia and NZ, presenting The National Groundwater Association’s prestigious 2017 Charles Darcy Lecture in Groundwater Sciences.
Dr Singha is a professor in the Department of Geology and Geological Engineering and the Associate Director of the Hydrologic Science and Engineering Program at the Colorado School of Mines. She worked at the U.S. Geological Survey Branch of Geophysics from 1997 to 2000, and was a member of the faculty at The Pennsylvania State University from 2005 to 2012.

To secure a premium market position for a food, one of the most popular strategies is to claim an intrinsic human health-promoting ability.
Fruits in general have an inherent natural ‘health halo’, with some fruit often classed as ‘superfruits’ and/or ‘functional foods’, because they are rich sources of different bioactive substances that can provide human health benefits beyond just their nutritional content.
A lot of marketing emphasis has been placed on antioxidant activity of fruit compounds for health, but unfortunately this mode of action is not well supported by science. In recent years, other mechanisms are being revealed that can explain why fruits and their compounds are healthy.
Dr Roger Hurst leads a team of researchers focused upon providing health science evidence to support the development of new fruit food products. He will present on the team’s strategic targets, their multi-pronged approach to building the science evidence from chemistry, cell screening to human clinical studies, and will give insights into key data from various fruits, that is leading to the creation of new and improved fruit-derived functional food opportunities in NZ and Asia.
Dr Hurst has a biomedical health background through a career at the University of Toronto, Canada; the Babraham Institute, Cambridge, UK; and the Institute of Neurology, London, UK. Since joining Plant & Food Research (2007) he has developed an interest in phytochemical compounds and their role in modulating oxidative stress, inflammation, and immunity to aid tissue recovery and repair.

A free public lecture by earthquake scientist Professor John Townend
WHEN: 6pm, Monday 14 August
WHERE: The National Aquarium of New Zealand Marine Parade, Napier
Professor John Townend will speak about lessons learned from recent and anticipated New Zealand earthquakes – including last year’s Kaikoura quake, one of the most complex earthquakes ever recorded.
Professor Townend is a geophysicist and Head of the School of Geography, Environment and Earth Sciences at Victoria University of Wellington. He co-leads the Deep Fault Drilling Project and is a Director of the Seismological Society of America. He is also Director of the EQC Programme in Seismology and Fault Mechanics at Victoria University of Wellington.
The past, present and future of integrated pest management in New Zealand fruit crops (July 2017)
Dr Jim Walker, Scientist in the Pipfruit & Winegrape Entomology team at Plant & Food Research delivered an excellent lecture at the Havelock North Function Centre to mark 150 years of the Royal Society Te Apārangi.
Pests and subsequently, the use of pesticide to deal with pests, has long been a problem for the New Zealand Pip Fruit industry, especially when it sought to gain access into new, high-value export markets. However, since the mid 1990s, the work carried out by Dr Jim Walker and his team has contributed to more than a 90 per cent reduction in insecticide use (kg/ha) by local apple growers. This includes the introduction of new natural enemies through to the development of selective pest management and use of semio-chemicals (pheromones) to support greater use of biological control in apple orchards. The development and implementation of these innovative pest control tactics are now central to today’s pest management systems.
Dr Jim Walker, entomologist and Principal Scientist with Plant and Food Research, talks about this research as well as the future sustainability and biosecurity threats facing the apple industry.
About the speaker:
Plant & Food Research scientist Dr Jim Walker leads a team of researchers focused on developing innovative tools and techniques for managing pests affecting the New Zealand horticultural industry.
During his 30 year career, he has been involved in the development and introduction of the Integrated Fruit Production (IFP) programme in the New Zealand pipfruit sector. The IFP programme has resulted in the sector adopting pest monitoring, pest prediction models and alternative control methods, enabling apple growers to substantially reduce their use of pesticides.
More recently Dr Walker has been involved with development of the sector’s ‘Apple Futures’ programme, focused on meeting the demand from consumers for high quality, residue-free fruit. He has also provided crucial guidance for the application of IFP to other sectors including wine grapes, summerfruit, citrus and onions.
