In the field of repair and regeneration, our challenge is to make hydrogels that retain the fatigue and resilience properties of the natural body part, but are comprised of nontoxic material. Resilin is a remarkable material exhibiting a broad range of stimuli-responsive behaviour and outstanding elasticity. The project aim is to create a tough and responsive hydrogel platform from this disordered protein family through greater understanding of structure and mechanical function and incorporating adequate stiffness, strength and biocompatibility. Such tough hydrogels would be applicable to a range of biotechnological applications (eg intervertebral disc repair or artificial skin tissue engineering).Read moreRead less
Tree-mediated methane fluxes: A new frontier in the global carbon cycle. Methane is an extremely potent greenhouse gas. Recent evidence suggests that tree-mediated fluxes may be a significant, but overlooked source of methane to the atmosphere. This project aims to quantify the magnitude and drivers of tree-mediated methane fluxes from Australia’s dominant forest types. Innovatively, we will be using a novel combination of empirical field based measurements, gas tracer experiments, microbial ana ....Tree-mediated methane fluxes: A new frontier in the global carbon cycle. Methane is an extremely potent greenhouse gas. Recent evidence suggests that tree-mediated fluxes may be a significant, but overlooked source of methane to the atmosphere. This project aims to quantify the magnitude and drivers of tree-mediated methane fluxes from Australia’s dominant forest types. Innovatively, we will be using a novel combination of empirical field based measurements, gas tracer experiments, microbial analysis and modelling methods. Expected outcomes are a mechanistic understanding of tree-mediated methane fluxes, helping to constrain regional, national and global methane budgets. The results of this study will help inform publicly funded greenhouse gas abatement strategies, ensuring a maximal return on investment.Read moreRead less
Keystone microbes and planktonic guilds in Australia's oceans. This project aims to unveil the ocean’s hidden sentinels, “keystone microbes” that underpin precious ecosystem services, and which can be used to monitor and model changes in ocean function. Marine microbes account for 90 per cent of oceanic biomass and every litre of seawater contains ~20,000 different species, but it is not known which species control ocean health and productivity. This project intends to provide definitive evidenc ....Keystone microbes and planktonic guilds in Australia's oceans. This project aims to unveil the ocean’s hidden sentinels, “keystone microbes” that underpin precious ecosystem services, and which can be used to monitor and model changes in ocean function. Marine microbes account for 90 per cent of oceanic biomass and every litre of seawater contains ~20,000 different species, but it is not known which species control ocean health and productivity. This project intends to provide definitive evidence of these keystones’ cellular level biogeochemical and metabolic capacity. Ultimately, this knowledge is expected to predict the resilience of ocean ecosystems and their response to change. The capacity to predict their dynamics will help provide investment clarity and increase healthy outcomes from activities involving human-ocean interactions such as recreation, food production and tourism.Read moreRead less
Plastic brains: Neural adaptations to changing environments in reptiles. The project aims to quantify brain anatomy on an unprecedented scale in comparative neurobiology. Focusing on Australia’s diverse and extensive collection of reptiles, including goannas, dragons and venomous snakes, the project expects to generate new knowledge on the evolution of brains as these animals adapted to new habitats and climates.

The project aims to quantify brain anatomy on an unprecedented scale in comparative neurobiology. Focusing on Australia’s diverse and extensive collection of reptiles, including goannas, dragons and venomous snakes, the project expects to generate new knowledge on the evolution of brains as these animals adapted to new habitats and climates. Data will be collected by cutting-edge micro-CT technology and advanced phylogenetic techniques, which will be complemented by detailed neuroanatomy. Expected outcomes include enhanced understanding of the effects of temperature on brains, and a large database of 3D digital anatomical models. A major benefit includes a greater ability to mitigate the effects of environmental change.Read moreRead less
Resilience in biogeochemical pathways along a catchment-to-coast continuum. Aquatic systems have degraded more in the past 50 years than any other time in history. Global pressures are further threatening their sustainability, but their complexity makes it difficult to understand how they are responding. This project will combine numerous state-of-the-art approaches to unravel pathways that shape their response.
Safer gene editing tools for Australian livestock and biotech industries. Editing the genome of an organism in an efficient and safe fashion is critical for the livestock and biotechnology industries. While CRISPR-Cas9 has become the method of choice for genome editing, it is known to introduce unwanted "on-target" and "off-target" mutations, limiting its utility. To address this the CI team created a novel genome editing platform technology termed Crackling-CAST that is almost 100% accurate, w ....Safer gene editing tools for Australian livestock and biotech industries. Editing the genome of an organism in an efficient and safe fashion is critical for the livestock and biotechnology industries. While CRISPR-Cas9 has become the method of choice for genome editing, it is known to introduce unwanted "on-target" and "off-target" mutations, limiting its utility. To address this the CI team created a novel genome editing platform technology termed Crackling-CAST that is almost 100% accurate, while retaining the efficiency of the classical Cas9 system. This project will exemplify the capabilities of the novel gene targeting platform in cell types used by the biotechnology and livestock sectors, ensuring its global uptake by these industries and delivering significant economic benefits for Australia.

This project aims to provide high-accuracy methods of evolutionary inference extendable to nearly all other organisms. It aims to research the evolution of animal diversity and calibrate evolutionary timescales on a case study of marsupial mammals, and differentiate between internal and external factors that govern animals’ ability to adapt and diversify. The project will collate a large, open-source three-dimensional catalogue of the evolving marsupial skeleton, which could provide a detailed and publicly accessible narrative of the evolutionary past and future adaptability of Australian marsupials. The proposed development of methods to quantify the effect of past and present biodiversity crises (e.g. environmental change) is expected to inform longer-term conservation planning.Read moreRead less
