A crackdown on unregulated peptides
Australia is facing a growing crisis in unregulated peptide use, with the Therapeutic Goods Administration (TGA) stepping up enforcement after alarming reports of dangerous, untested substances being sold online. These peptides—often marketed with names like 'Wolverine stack'—include compounds such as melanotan and retatrutide, which lack human trials and carry serious risks, including increased skin cancer risk. The TGA's crackdown comes amid broader concerns about the integrity of medical research in Australia, highlighted by a scathing editorial in Science Magazine criticizing the National Health and Medical Research Council’s (NHMRC) shift to anonymous, non-interactive peer review. Researchers argue this change has eroded accountability and debate, potentially undermining the quality of funded science. In response, NHMRC CEO Steve Wessling defends the new system as more efficient and better aligned with expert reviewers, while acknowledging global challenges like AI-driven grant inflation. Meanwhile, a groundbreaking study shows that population-scale genomic screening could identify 1 in 50 Australians at high risk for preventable diseases like hereditary cancer and heart conditions—yet the healthcare system is unprepared to handle the downstream care. Despite strong public interest, infrastructure and access remain major barriers.
1 in 50 Australians carry high-risk genetic variants for preventable diseases like hereditary cancer and familial hypercholesterolemia, yet current systems don’t detect them early.
Population genomic screening is feasible and highly desired by Australians, but the public health system lacks the infrastructure to handle follow-up care at scale.
Only 20% of women report severe pain during IUD insertion—challenging social media myths and highlighting that fear, not pain, is the main barrier to uptake.
The NHMRC’s shift to anonymous, non-interactive peer review has eliminated accountability and debate, raising concerns about the quality of funded research.
AI is increasing grant applications and compressing quality, making it harder to distinguish truly innovative research from well-written proposals.

Genomic Screening: A Preventive Revolution
“We tested, as you said, 10,000 people, just over 10,000. 202 brought it to about 2%, 1 in 50 people who had this really high risk of disease.”
“So, there is no debate, there is no accountability of the individual assessors. Is it having an impact on the grants that are being given? Are they being given to second -rate proposals?”
