Wasps are forever? The potential to eliminate an invasive pest in New Zealand; permissions withstanding - Genomics Aotearoa

Dec 21, 2020

By Gemma McLaughlin, University of Otago PhD candidate Invasive social wasps have long plagued New Zealand’s beech forests and suburbs. Now, a  genetic technology holds the potential to stop such wasps in their tracks. But one major issue lurks: are scientists even allowed to explore this option? New Zealand summers are a great thing. We have our kiwi classics: the barbecues, the beaches, the roadie. But we also have a less than welcome visitor that can serve as a source of irritation or just a downright disruption to the festivities; the social wasp. These winged nuisances thrive in our environment, with densities higher here than anywhere else in the world – not really something we can brag about! And while they can be an annoyance for us, they are a much bigger problem for other species residing here. Native caterpillars … Read More

Changing stuff… - Genomics Aotearoa

Nov 25, 2020

By Professor Peter Dearden, Director Genomics Aotearoa Science is an excellent way of allowing us to question test and understand the world we live in. But that knowledge also provides us with something else; the ability to change things, to solve problems, and to make life on earth a bit better. This is clearly the case in medicine; by understanding a disease, and the way it interacts with the body, we can find ways to intervene, to improve outcomes and perhaps find a cure. And it is commonplace in other sciences; problems of mass communication are solved with electronics, lightweight batteries and radio waves, leading to the cell phone in your hand, and the remarkable changes in our society these devices have caused. This is the role of science, not just to understand, but to improve and … Read More

Indigenous perspectives on unrestricted access to genomic data - Genomics Aotearoa

Sep 23, 2020

By Genomics Aotearoa researcher Maui Hudson, University of Waikato It is vital that genomics research respects genomic data and genetic heritage from indigenous communities. Genomics research is a rapidly growing field of study, and there is a strong push to make the huge amount of data being produced open source for all researchers to use – the rational being that more available science creates greater societal benefits. But we know that isn’t actually the case, and that unrestricted access to genomics data can lead to injustice. We –  myself and a group of New Zealand from the University of Waikato, University of Otago and University of Canterbury, Crop and Food Research and Manawaora The Centre for Health, Tauranga, teamed up with international researchers from prominent research organisations in the United States, Canada, Australia, South Africa and Spain to delve … Read More

Tackling the hard issues – trust and relationships - Genomics Aotearoa

Sep 15, 2020

By Claire Grant, Genomics Aotearoa Communications Manager Community consultation is becoming an increasingly important aspect of research programmes in New Zealand, and with that comes the art of relationship building. Engagement between scientists and user-groups is certainly nothing new. But as stakeholder involvement becomes more of a requirement for science, it becomes harder to define what constitutes effective consultation, and what a community partnership looks like in practice. And that has implications for our traditional skill sets – it’s no longer simply packaging science through education and disseminating published science results. It requires a meaningful relationship. Engagement is not a tradition taught subject and may not necessarily be something we’re all good at. But I’d argue we could stop thinking of “soft skills” as an add-on, and instead consider them a list essential for career success.  In other words, we … Read More

Containers for reproducible bioinformatics research - Genomics Aotearoa

Aug 12, 2020

By Aleksandra Pawlik, Ngoni Faya, Joseph Guhlin, Megan Guidry, Tom Harrop, Dinindu Senanayake Rapid development of computational bioinformatics tools mean we can more easily push research boundaries. However, it comes at a cost. The complexity of the software chain that needs to be installed and configured to run advanced workflows results in researchers spending hours, if not days, trying to set up and debug the computational environment before they can even start to analyse their data. Complex setups also hinder reproducibility, one of the core principles of science. Fortunately, there is a solution growing in popularity – containers. Simply put, containers allow wrapping up software packages in an executable environment which can be moved from one computer to another regardless of which operating system these computers run. You can think of it as a “computer inside a computer”, contained … Read More

Data analysis skills are in hot demand – what should we be doing about it? - Genomics Aotearoa

Jul 29, 2020

By Associate Professor Mik Black, Department of Biochemistry, University of Otago The increased availability of complex biological data sets means that analysis and computation are becoming critically important skills for New Zealand’s future scientists. Because of this, we need to be doing everything we can to help our students develop these skills, to better prepare them for large-scale data analysis across a range of fields. At present, students focusing on the biological sciences in New Zealand tend not to take the more “computational” subjects – statistics, mathematics, computer and/or information science – yet the growing importance of data manipulation and analysis in genomics make these important and sought-after skills. While there are now more students coming through biology-focused programmes like genetics and biochemistry who are starting to include computational/analytic training (great to see), those numbers need to grow. What is … Read More

Better understanding bacterial blooms in New Zealand waterways - Genomics Aotearoa

Jul 13, 2020

Dr Kim Handley, University of Auckland Just how do cyanobacteria live in their natural habitat, and how do they coexist with other bacteria and microbial life forms? And what difference will knowledge on this bacteria have on maintaining New Zealand’s water quality? One of the consequences of declining water quality is an increase in cyanobacteria – these are photosynthetic bacteria that live in a wide variety of aquatic or wet habitats. While they are integral to many aquatic systems, too many cyanobacteria are not a good thing – under favourable conditions cyanobacteria can multiply and form blooms, which can have a serious impact on the environment. Some cyanobacterial species produce natural toxins, which not only affect river ecosystems and aquatic life, but also threaten human and animal health – thick mats formed by Microcoleus for instance are well known for dog … Read More

Genomic breakthrough in invasive species management - Genomics Aotearoa

Apr 15, 2020

Nick Kachel The ship rat, or black rat, is one of the most infamous invasive species in the world. They’re intelligent, adaptable, and they multiply like… well… ship rats. A native to the Indian sub-continent, this pest has now spread to every corner of the globe and is an outstanding carrier for multiple zoonotic diseases – those which can be spread from animals to humans. New Zealand is no stranger to the species. They first arrived in the country on European ships in the 19th century and quickly went about making a home for themselves. They can be found across the country in native forests, scrublands, and urban parklands. They are one of the biggest threats to biodiversity in New Zealand. As well as spreading disease and affecting agricultural production, the ship rat also preys on bird eggs and chicks, … Read More

The importance of the humble blueberry - Genomics Aotearoa

Feb 26, 2020

Dr David Chagné New Zealand is involved in a US$12.8 million USDA grant to improve the quality of blueberry and cranberry. The four-year project, led by North Carolina State University, is part of the USDA’s National Institute of Food and Agriculture Specialty Crop Research Initiative, which funds multi-year, multi-institutional collaborative projects. Genomics Aotearoa and Plant and Food Research Ltd have just become part of this project, and we’re very excited about what that offers – for blueberry producers here, for the New Zealand economy, the consumer and for other genomics researchers. But what does this actually mean for us? As with all genome research, the solution is not in the sequencing itself, but in the opportunities it provides to use the genetic information for good. And for us, it’s not just the research results but also the potential to leverage … Read More

Finish what’s on your plate - Genomics Aotearoa

Nov 04, 2019

Murray Cox Do I have to finish my favourite genome? That’s an often-asked question. Geneticists generally strive to produce high-quality genomes that sequence every last gene, making full use of the state-of-the-art technologies coming on stream. Sequencing DNA means determining the order of the four chemical building blocks – called “bases” – that make up the DNA molecule. The sequence tells scientists the kind of genetic information that is carried in a particular DNA segment. For example, scientists can use sequence information to determine which stretches of DNA contain genes and which stretches carry regulatory instructions, turning genes on or off. Importantly, data from a genome sequence can highlight changes in a gene that may cause disease. Reference genomes are the cornerstone of modern genomics. These high-quality genomes are differentiated from draft genomes by their completeness – few gaps, low … Read More
