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.

Overcoming antibiotic resistance: rapid discovery of new antibacterial drug targets using chemical proteomics. The prevalence of multidrug-resistant bacteria in the community is a critical public health issue and there is an urgent and compelling need for new antibiotics with novel modes of action to combat these deadly superbugs. While antibiotics from nature have long been a mainstay of the pharmaceutical industry, their development as drugs can be challenging as their cellular targets and mod ....Overcoming antibiotic resistance: rapid discovery of new antibacterial drug targets using chemical proteomics. The prevalence of multidrug-resistant bacteria in the community is a critical public health issue and there is an urgent and compelling need for new antibiotics with novel modes of action to combat these deadly superbugs. While antibiotics from nature have long been a mainstay of the pharmaceutical industry, their development as drugs can be challenging as their cellular targets and modes of action are frequently unknown. In this project, innovative chemical proteomics approaches will be used to rapidly identify and characterise the cellular targets and modes of action of both newly discovered and historic antibiotic natural products, thereby overcoming this bottleneck and accelerating the development of next-generation antibiotics.Read moreRead less

Summary
High-throughput, high resolution protein-peptide sequencing and quantification facility. This facility will enhance the research capability of scientists at The University of Queensland who are using mass spectrometry to elucidate the structures of novel toxins which have the potential to be developed as drugs.
Structure and function of predatory and defensive venoms in cone snails. This project aims to investigate newly-discovered cone snail venoms to accelerate the search for novel bioactive peptides. It was recently discovered that cone snails can rapidly and reversibly switch between distinct venoms in response to predatory or defensive stimuli, implying that defensive and predatory venoms have evolved under separate selection pressures. The project plans to obtain separate predatory and defensive ....Structure and function of predatory and defensive venoms in cone snails. This project aims to investigate newly-discovered cone snail venoms to accelerate the search for novel bioactive peptides. It was recently discovered that cone snails can rapidly and reversibly switch between distinct venoms in response to predatory or defensive stimuli, implying that defensive and predatory venoms have evolved under separate selection pressures. The project plans to obtain separate predatory and defensive venoms and venom duct tissue from individual cone snails to compare and contrast the structure and function of conotoxins evolved for predation versus those evolved for defence, to elucidate the structure and function of these important classes of bioactive peptides.Read moreRead less
