The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

MicroRNA Expression And Genome-Wide Epigenetic Analysis Of Paediatric Acute Lymphoblastic Leukaemia (ALL)
Funder
National Health and Medical Research Council
Funding Amount
$71,765.00
Summary
Acute Lymphoblastic Leukaemia (ALL) is one form of childhood leukaemia, the causes for which are unknown. Evidence suggests genome changes are associated with ALL, specifically epigenetic changes such as DNA methylation and microRNA dysregulation. We aim to investigate these changes associated with childhood ALL. We believe this will refine the current diagnostic measures, more accurately predict patients� treatment response, and detect the minimal residual disease during and after treatment.
Spinosyns As Endectocides For Blocking Transmission Of Malaria And Other Mosquito-borne Diseases

Funding Amount

Summary
Malaria is a disease caused by a parasite. It is transmitted by mosquitoes and kills 400,000 people annually. To prevent malaria we must stop transmission. We have discovered a natural substance that, if ingested, makes an animal's blood lethal to at least one type of mosquito. It also kills the parasite. We aim to determine if it kills other key mosquito types and how it kills the parasite. We expect this study will lead to a pill that stops transmission of malaria and other tropical diseases.
I am a neurophysiologist interested in brain regulation of homeostatic and autonomic functions in health and disease. I am endeavouring to discover the brain pathways for these vital functions, and to translate my findings from animal research to humans.
Patients With Obstructive Sleep Apnoea And Motor Control
Funder

Funding Amount
$302,798.00
Summary
Obstructive Sleep Apnoea is a major health concern, affecting at least 4% of the population, associated with obesity, and aging. The symptoms of sleep apnoea are definitively associated with cardiovascular complications. I am focused on understanding how sleep apnoea patients are remodelled with the rewiring of connections between the brain and muscles. Using neurophysiological techniques, this project will study how the anatomy and functional connections of circuits change with sleep apnoea.
Signalling Of Muscle Force By Golgi Tendon Organs During Exercise And Fatigue

Summary
It is a common experience for objects being carried to feel heavier and tasks needing muscular effort to become more difficult as one becomes tired and the muscles fatigue during exertion. The sensation of muscle force depends on two factors. One, a sense of the effort required to perform a task, is generated in the central nervous system and. The other, a sense of the force actually developed by the muscles, is generated in the muscles themselves by signals from sensory receptors called Golgi t ....It is a common experience for objects being carried to feel heavier and tasks needing muscular effort to become more difficult as one becomes tired and the muscles fatigue during exertion. The sensation of muscle force depends on two factors. One, a sense of the effort required to perform a task, is generated in the central nervous system and. The other, a sense of the force actually developed by the muscles, is generated in the muscles themselves by signals from sensory receptors called Golgi tendon organs. The sensation of muscle force and the heaviness of objects results from a combination of both senses, but the contribution of each is unknown. The aim of the project is to determine whether the disturbance of force sense in fatigued muscles results from changes in the way tendon organs signal the actual force developed by the muscles. This will be important for understanding how force sense is disturbed following exercise and in disease states, and for understanding the normal way muscle force is sensed in everyday situations. Disturbances of force sense after exercise will be documented in human subjects by asking them to generate what they perceive to be equal forces in both arms or legs, before and after one limb only is exercised. Errors in force estimation will show up as mismatches between the two limbs. The difficulty with human experiments is that the signals generated by tendon organs cannot be measured directly, but only inferred, perhaps wrongly. This difficulty will be overcome by measuring tendon organ activity directly in anaesthetised animals, where the muscles will be electrically stimulated to perform exercise similar to that in the human experiments. A change in tendon organ signalling will be taken to mean that similar changes in humans could be responsible for disturbances of force sense. In further experiments, the mechanism of the changes will be explored.Read moreRead less
Release The Sterile Males: A New Direction For Mosquito Population Control Technologies

Funding Amount

Summary
With over 40% of humans at risk from mosquito-borne disease, new environmentally friendly mosquito control tools are required. We’ve developed a novel sterile male population suppression technology – using neither radiation nor genetic modification – to produce sterile adult male mosquitoes from both male and female larvae. We will show that exposing mosquito larvae to specific RNA molecules can produce fit sterile males adult mosquitoes that can crash mosquito populations in large cage trials
