Babies in Australia have been vaccinated against hepatitis B since May 2000, but 240,000 Australians still live with the disease.
Wondering if that latest study finding is too good to be true, or whether it's as bad as we're told? Here are five questions to ask to help you assess the evidence.
Most medical research is funded by industry, not public sources. And industry puts pressure on researchers in many ways, from guiding the research question to suppressing unfavourable findings.
Researchers are looking for ways to determine who's most at risk for dementia and also ways to detect it early. A scientist who has studied low blood pressure makes a case for a link between the two.
From cutting-edge research, to public education, journalism and even schoolkid scientists, Australia's best science was on display at the annual Eureka Prizes.
Long-term or historical use of oral contraceptives may lead to an increased risk of depression in later years; understanding the risk will better inform the decision whether or not to take the pill.
Thomas Durcan's lab is growing 3D mini-brains in the search for a cure for Parkinson's disease. Over the next year he is giving all his lab's protocols, methods and results away.
Deliberately infecting people with a disease-causing agent as part of carefully considered medical research can be ethically acceptable or even necessary.
Medical research has a dark history of human experimentation in Nazi Germany. And we're still uncovering the extent of the horrors.
Research milestones in the study of memory may help us find solutions to memory disorders like Alzheimer's or recovery from brain trauma.
The Gila monster gave humans a treatment for diabetes. What other medical miracles are we losing by failing to protect wildlife and ecosystems?
Questions abound about whether the scientist who created the first gene edited human beings took shortcuts in the ethical oversight process. But pedantically focusing on protocol misses the point.
Medical advances were the only positive things to come out of the Great War.
Once associated with mind-control experiments and counter-cultural defiance, psychedelics now show great promise for mental health treatments and may prompt a re-evaluation of the scientific method.
If we want My Health Record data to be made available for medical research we need to make it opt in, not opt out. We'll have a smaller dataset, but at least it will be ethically defensible.
Koro is widely believed to be a culturally localised delusion. But a theory that it's a fight-or-flight reflex might be corroborated by studying traditional healing treatments in Indonesia.
Data ethics should pay much more attention to the social value of research
The journal initially only published articles by European physicians. But in the 20th century a number of Indonesians, who became founders of respected medical institutions, published there too.
Non-use of data may be an even bigger problem that its misuse.
Many cities could learn from Dundee, which overcame industrial decline to become a UNESCO City of Design, with a shiny new cityscape to match
