Dengue fever infections dropped dramatically in an Indonesian study where a bacteria was introduced into disease-carrying mosquitoes, offering hope in the battle against an illness that sickens millions annually around the world.

Variants of viruses, such as that causing COVID-19, can now be quickly studied in the laboratory, even before they emerge in nature and become a major public health challenge.

New research by The University of Queensland and QIMR Berghofer Medical Research Institute has revealed how lowering cholesterol could potentially prevent or help stop the spread of prostate cancer.

Around 1 in 9 Australian women will suffer from endometriosis at some point in their life. With Endometriosis, tissue similar to the lining of the uterus (the endometrium) grows in other parts of the body, often causing severe symptoms that puts life on hold during a woman’s period. Typically treatment focuses on pain management using medication or hormone therapy, and often laparoscopic surgery to remove scarring and adhesions on the reproductive organs, bladder, bowel and other affected organs. There is no currently cure. Now a new theory has been developed by researchers at Canada’s Simon Fraser University (SFU) that suggests a previously overlooked hormone, testosterone, has a critical role in the development of endometriosis. Their research could have direct impacts on diagnosis and treatment of the disease, signalling hope for women worldwide.

Australian researchers say they have taken an "important step forward" in developing a universal T cell-based influenza vaccine that would be more effective for Indigenous people worldwide.

A team of Australian and US scientists from Menzies Health Institute Queensland (MHIQ) at Griffith University and from US research institute City of Hope, has developed an experimental direct-acting antiviral therapy to treat COVID-19. Lead researcher Professor Nigel McMillan from MHIQ said: "It causes the genome to be destroyed and the virus can't grow anymore. So we inject the nanoparticles and they go and find the virus and destroy it just like a heat-seeking missile."

A dengue virus vaccine candidate has passed an important milestone, with promising results in animal model testing providing hope to the 390 million people infected every year. The University of Queensland-developed vaccine candidate, applied to the skin via the high-density microarray patch (HD-MAP), has produced a protective immune response in dengue-infected mice.

A study across 55 Queensland hospitals suggests that a recent state policy to introduce a minimum ratio of one nurse to four patients for day shifts has successfully improved patient care, with a 7% drop in the chance of death and readmission, and 3% reduction in length of stay for every one less patient a nurse has on their workload.

A set of physical activity for pregnancy guidelines, developed by The University of Queensland and CQUniversity, was released by the Australian Government Department of Health on Mother's Day.

Australian researchers hope to save significant time, money and resources in hospital wards, with findings from a new University of Queensland-led study published in The Lancet.
