The research aims to determine if unhealthy work environments contribute to Australia's high levels of depression and anxiety.
A new study found that most Australian GPs have used a placebo in practice at least once, with active placebos being more commonly used than inert ones. The study suggests that GPs use placebos because they believe it can provide genuine benefit and shape patients' expectations.
Researchers argue that academic journal rules are undervaluing the contributions of citizen scientists and indigenous knowledge. To address this issue, they suggest crediting non-professionals as group co-authors for their work on projects like online species identification apps. This approach aims to recognize their valuable contribut...
US President Donald Trump's Twitter use 'hyper-personalised, character assassinated and used unprofessional language' to gain support, the authors say. His tweets proved devastatingly effective in the 2016 election campaign.

USC scientists discover coral passes beneficial algae colonies to offspring for survival advantage. The finding suggests corals can adapt to rising ocean temperatures through genetic mechanisms.
A study of 585 cancer patients in Australia and Vietnam found that 'bad luck' or fate was the third most common perceived cause of their cancer. This misconception can lead to a lack of willingness to change behavior related to diet, lifestyle, treatment, and care.
A recent study on palorchestid marsupials reveals they were giant herbivores that likely filled a niche no longer occupied in modern Australian ecosystems. The animals' forelimbs were extremely muscular and had fixed elbow joints, adapting them as permanently flexed food-gathering tools.
A new study by a University of Arkansas anthropologist suggests that feeding habits of an extinct kangaroo species were similar to the modern-day giant panda. The analysis of the skull biomechanics of a giant extinct kangaroo indicates that it had a capacity for high-performance crushing of foods.
