As we bid farewell to 2025, it is clear that the year has been marked by significant scientific breakthroughs and health insights that captured public attention. From medical advancements to environmental concerns, these stories not only informed but also sparked widespread discussion. Here, we delve into five of the most-read stories of the year, each shedding light on different facets of our world.
Weight Loss Drug Mounjaro Approved for Sleep Apnoea
In a landmark decision earlier this year, the Therapeutic Goods Administration (TGA) approved the weight-loss drug Mounjaro for the treatment of moderate to severe obstructive sleep apnoea in adults with a body-mass index of 30 or above. This approval marks a significant step in addressing a condition that affects millions worldwide.
Mounjaro, originally used for diabetes treatment, has shown promise in helping individuals breathe easier at night. The article, authored by Professor of Sleep Health Fatima Yaqoot and Research Program Manager Nisreen Aouira from the Thompson Institute, explores how this drug functions and its potential impact on sleep health.
Gut Microbiome and ADHD: A Reinforced Connection
The intricate link between gut health and neurological conditions was further underscored by a scientific review from the University of the Sunshine Coast. The review, conducted by Naomi Lewis and Dr. Anthony Villani, highlighted the role of gut microbiome imbalances in exacerbating ADHD symptoms.
The researchers found that specific bacteria, such as Bacteroides and Faecalibacterium, were altered in individuals with ADHD, potentially leading to inflammation that affects the brain. This research adds to the growing body of evidence suggesting that gut health is crucial for mental well-being.
“Mounting evidence shows the immune system, neuroinflammation, and a disturbed balance of bacteria in the gut play a role in ADHD symptoms.”
Surfers Fall Ill from ‘Bacterial Smoothie’ Sea Foam
In March 2025, South Australia’s beaches became the center of attention after over 100 surfers fell ill due to exposure to dense sea foam. This mysterious phenomenon was linked to a harmful microalgal bloom containing high levels of Nocardiae bacteria, prompting beach closures and public health warnings.
Associate Professor Ipek Kurtböke provided an in-depth analysis of the event, emphasizing the need for increased research and public awareness to mitigate such environmental hazards. The incident highlights the broader issue of pollution and its impact on marine ecosystems.
Debunking Fitness and Nutrition Myths
In an era where social media is rife with misinformation, three sports nutrition experts took on the challenge of debunking prevalent food and exercise myths. Their insights provided clarity on topics such as the efficacy of the carnivore diet, the benefits of fasting before workouts, and the role of magnesium in post-training recovery.
These experts stressed the importance of evidence-based dietary advice, particularly in a digital landscape where unqualified creators often spread misleading information.
Leopard Shark Mating Captured on Film
In a scientific first, researchers documented a rare mating sequence of leopard sharks in the wild. Filmed off the coast of New Caledonia, this footage provides valuable insights into the reproductive behaviors of these endangered animals, which are typically solitary.
The discovery of this critical mating habitat could inform future conservation strategies and enhance our understanding of shark population dynamics. This remarkable finding underscores the importance of preserving marine biodiversity.
As we reflect on these stories, it is evident that 2025 has been a year of discovery and enlightenment. These breakthroughs not only advance scientific knowledge but also pave the way for future research and policy development. As we move forward, the lessons learned from these stories will continue to shape our understanding of health, environment, and the natural world.
