A new study from the University of Oulu suggests that gut bacteria may send different biological signals in Parkinson’s disease.

Experts at the University of Sydney have found that a gene involved in regulating the body's response to stress switches on more easily in the brains of people who live with schizophrenia.

A mother's obesity during pregnancy may send molecular signals across the placenta that permanently alter her son's liver metabolism, according to a new study in mice published in Nature Communications.

Superfund sites typically cluster in low-income communities, where 62% of households earn less than $50,000 annually.

Obesity and eating disorders have traditionally been treated as separate areas of healthcare – but the rapid rise of GLP-1 medicines is increasingly bringing the two together.

A WEHI-led project has received $7 million in Australian Government funding to expand the nation’s drug discovery capabilities and accelerate the translation of breakthrough research into new therapies.

Wiley, a global leader in authoritative content and research intelligence, today announced the launch of its spectral analysis application programming interface (API) portfolio, providing users with a new, faster way to access its trusted spectral data, analytical algorithms, and predictive models–within their own workflows.

Researchers developed a SuperLearner framework that combines established epigenetic clocks with machine learning to compare DNA methylation-based aging in residents of Costa Rica’s Nicoya Blue Zone with other Costa Ricans. Initial calibration suggested a modest younger epigenetic age among Nicoyans, but accounting more closely for age distribution substantially reduced the apparent advantage, highlighting the importance of population-specific calibration in longevity research.

Interviews with 11 healthcare professionals in a UK specialist weight management service found generally positive attitudes toward injectable GLP-1 drugs, alongside limited formal training and uncertainty about how the medications should be integrated with behavioral care. Participants anticipated potential benefits for confidence and weight management but also raised concerns about treatment discontinuation, behavioral engagement, and evolving professional responsibilities.

Pertussis, or whooping cough, continues to cause periodic outbreaks worldwide and can be especially dangerous for infants who have not completed vaccination.

Do you ever feel like sometimes you can master a new dance step almost immediately, while other times you struggle to nail it despite repeated practice? This might be due to skill or effort, but also to something less obvious: whether the brain is in a state that allows learning to take hold.

Nicotine e-cigarettes are more effective in helping people quit smoking than many conventional methods such as nicotine gums and patches and quitting with behavioural support or no support at all, an updated Cochrane review finds.

A critical narrative review found that healthy diets, regular physical activity, strong social ties, and psychological well-being can support healthier aging and reduce premature mortality, but none has been shown to reliably determine who reaches 100. The authors argue that exceptional longevity arises from complex interactions among biological resilience, genetics, social and environmental conditions, lifelong exposures, and chance rather than any universal lifestyle formula.

Millions of cases of tooth decay could be prevented if Australia introduced a 20 per cent tax on sugar, new Griffith University research has found.

Building on recent discoveries about the adult thymus, Mass General Brigham investigators used artificial intelligence to show that incidental radiation exposure to the thymus may influence outcomes in patients with lung cancer.

A multicenter Japanese study found that symptomatic uncomplicated diverticular disease (SUDD) was associated with reduced gut microbial diversity, increased abundance of the Ruminococcus gnavus group, and depletion of Coprococcus and other butyrate-producing bacteria. Predictive microbiome analysis also identified enrichment of pathways linked to exopolysaccharide biosynthesis and the cell cycle, although the observational design means these associations cannot establish causality.

Until recently, the thymus was thought to be of little use beyond puberty, but new research has shown that radiation to the organ is associated with worse outcomes in patients being treated for non-small cell lung cancer (NSCLC).

Diet-induced weight loss significantly reduced predicted 10-year risks of major adverse cardiovascular events and type 2 diabetes in healthy premenopausal women with overweight, regardless of whether aerobic or resistance exercise was added. Some of these gains diminished as weight was partially regained over the following year, although greater exercise adherence was associated with less rebound in predicted diabetes risk.

Black parents who experienced higher levels of appropriated racial oppression - defined as shaping one's behavior and self-concept around dominant cultural norms of whiteness - were less likely to transmit positive, culturally protective messages that affirmed racial pride and self-worth to their adolescent children, a recent study found.

Researchers have developed a "scaffold" that mimics natural tissue and could lead to more durable rotator cuff repairs, including for large injuries and cases involving bone and tissue degeneration that are often the most difficult to fix.
