Temperature sensitivity of soil respiration and its components. This project aims to demonstrate how temperate evergreen forests could buffer against climate change. Soil respiration returns around half the carbon taken up by forests to the atmosphere. This project will characterise and quantify how microbes and roots in soils depend on temperature and substrate supply, and so predict how rising temperatures and drought will affect forests as natural carbon sequestration sinks. This project will ....Temperature sensitivity of soil respiration and its components. This project aims to demonstrate how temperate evergreen forests could buffer against climate change. Soil respiration returns around half the carbon taken up by forests to the atmosphere. This project will characterise and quantify how microbes and roots in soils depend on temperature and substrate supply, and so predict how rising temperatures and drought will affect forests as natural carbon sequestration sinks. This project will resolve the roles of environmental drivers of soil respiration across forests; integrate mechanistic understanding of differing plant and microbial responses to temperature within a common modelling framework; and evaluate the implications of this knowledge in predictions of climatic impacts on terrestrial carbon cycling.Read moreRead less
Calibrating Cosmology: The Near-Field Approach to Galaxy Formation. Understanding the formation and evolution of structure in the early Universe continues to elude astronomers. Studying these earliest epochs is the driver for billion-dollar investments like the Next Generation Space Telescope and the Square Kilometre Array (with Australia as a primary partner). Our complementary 'near-field cosmology' project is unique, blending strengths in computational cosmology, stellar nucleosynthesis, and ....Calibrating Cosmology: The Near-Field Approach to Galaxy Formation. Understanding the formation and evolution of structure in the early Universe continues to elude astronomers. Studying these earliest epochs is the driver for billion-dollar investments like the Next Generation Space Telescope and the Square Kilometre Array (with Australia as a primary partner). Our complementary 'near-field cosmology' project is unique, blending strengths in computational cosmology, stellar nucleosynthesis, and optical astronomy, to 'deconstruct' the formation history of the one galaxy with detailed chemical and kinematical information - our own Milky Way. Combining theory and observation, cosmology and nucleosynthesis, we will produce the template for galaxy formation, providing the anchor for 'far-field' cosmology.Read moreRead less

New technology developed by Australia, Sweden and the United States will be applied to major questions about the application of relativistic quantum mechanics to atomic structure and dynamics and spectroscopy, especially including critical issues in quantum electro-dynamics for atomic physics and applications. Discrepancies in quantum electro-dynamics have dominated international debate for decades, with claimed explanations annually failing to reveal the cause. Also a pattern of discrepancies has been seen at X-ray energies in first row metal atoms, with a similar sign and magnitude. A combined experimental an theoretical investigation will aim to reveal new light on these anomalies and serve to develop our understanding of the universe.Read moreRead less
Adaptive Evolution of BRCA1 in Ancestral Mammals. This project investigates adaptive evolution of BRCA1 in the early radiation of mammals. We will test the hypothesis that the evolution of mammary glands and X chromosome inactivation has resulted in modification of the BRCA1 protein sequence as it aquired new roles in these processes. We will also investigate the importance of these changes inducing compensatory changes in other parts of the protein.
Taming the intruders: the domestication of Tigger transposable elements in mammals. It has become apparent that most of the DNA that makes us what we are is actually comprised of the remnants of invading parasitic DNA acquired over time. A continual battle exists between host which tries to silence or remove this DNA, and the parasite that tries to multiply and spread. We are currently investigating an intriguing aspect of this process that involves host genomes 'domesticating' parasitic DNA to ....Taming the intruders: the domestication of Tigger transposable elements in mammals. It has become apparent that most of the DNA that makes us what we are is actually comprised of the remnants of invading parasitic DNA acquired over time. A continual battle exists between host which tries to silence or remove this DNA, and the parasite that tries to multiply and spread. We are currently investigating an intriguing aspect of this process that involves host genomes 'domesticating' parasitic DNA to provide novel functions, thereby facilitating the evolution of specific characteristics within species.Read moreRead less
Boosting C4 photosynthesis to climate proof crop yields. Building next generation C4 crops, such as maize, sugarcane and sorghum, to cope with drought and heat stress is requisite to ensure the supply of food and fodder. Here we will increase the content and / or catalytic efficiency of the primary carboxylase of C4 photosynthesis (PEPC) that supplies CO2 to the carbon concentrating mechanism and ensures high photosynthetic rates.

Here we will increase the content and / or catalytic efficiency of the primary carboxylase of C4 photosynthesis (PEPC) that supplies CO2 to the carbon concentrating mechanism and ensures high photosynthetic rates. We will develop new SynBio tools to create and test novel PEPC isoforms with desirable properties. Ultimately, the project aims to identify isoforms that improve plant fitness under stress conditions.

Stawell Underground Physics Laboratory: Dark matter detector development. This project aims to develop ultra-sensitive detector technology essential for SABRE, a Northern and Southern Hemisphere dual-detector experiment. The SABRE facilities operate to directly detect galactic dark matter. Dark matter makes up 23% of the observable universe but the evidence for its existence is indirect. The direct detection of dark matter would be a discovery on par with gravitational waves and the Higgs boson. ....Stawell Underground Physics Laboratory: Dark matter detector development.
