A new study reporting in Translational Psychiatry suggests that a traditional medicinal formulation called Rannasangpei-and particularly its constituent crocin-1-may help blunt autism-like behaviors triggered by prenatal exposure to valproic acid (VPA). The work frames autism-related impairments not only as behavioral phenomena, but also as downstream consequences of disrupted redox balance and chronic neuroinflammatory signaling in the brain.

Sleep has long been suspected to influence how aging bodies manage multiple chronic conditions, but the interplay between rest quality and physical decline has been harder to untangle. Now, a new cross-sectional study of Chinese older adults adds an evidence-packed twist: poor sleep and frailty are not just independently linked to cardiometabolic multimorbidity-they also appear to act synergistically.

Gut microbes are increasingly being viewed as hidden regulators of brain health, and a new study in Translational Psychiatry adds fuel to that idea by tracing a biochemical pipeline from the gut to stress-related mental disorders. The research, led by Yuan, Qin, Wu and colleagues, reports that metabolites produced-or shaped-by gut microbiota can influence developmental trajectories associated with anxiety- and stress-linked pathology.

A new study reported in BMC Geriatrics spotlights cognitive reserve-the brain's lifelong ability to adapt-as a potential resilience factor for how older adults experience frailty. The research frames frailty not as a fixed state, but as a dynamic process that can worsen or improve over time, with cognition playing a key role in that trajectory. Frailty affects mobility, independence, and health outcomes, and clinicians increasingly treat it as something that evolves.

Older adults in China are not experiencing health improvements evenly, and a new study links part of that gap to how physical activity is distributed across communities. Researchers report that physical activity is associated with better health outcomes, but the benefits are not uniform-creating measurable health inequality rather than a single "one-size-fits-all" effect.

A new study is turning an elegant quantum idea into a practical platform for light. In research published in Light: Science & Applications, physicists report "topological Jackiw-Rebbi" states engineered inside photonic van der Waals heterostructures-systems built by stacking atomically thin materials with

A new analysis from a large, single-centre cohort suggests that when immune checkpoint inhibitors are given can meaningfully shape outcomes for patients with advanced cancer. The study, reported in British Journal of Cancer, examines overall survival in relation to the timing of therapy administration, moving beyond the usual question of whether immunotherapy works to asking how its scheduling may alter the odds.

A new study highlights what shapes how older adults choose dental services, offering insights that could help clinicians and policymakers make care more reachable for aging populations. Published in BMC Geriatrics, the research examines preferences from the perspective of elderly people, focusing on the practical and psychological drivers behind where they seek treatment. Researchers report that dental service choice is not determined by clinical need alone.

A new study in npj Urban Sustainability points to the practical levers that determine whether stormwater systems actually deliver long-term sustainability. As cities expand and rainfall extremes intensify, green and nature-based infrastructure has been promoted to capture runoff, reduce flooding, and protect water quality. But the research warns that success is not automatic: design decisions and operational realities can make or break performance.

A team of neuroscientists has reported that deep brain stimulation (DBS) targeted to the motor thalamus can reshape how the brain controls both speech and swallowing-and crucially, that the outcome depends on stimulation frequency. The findings, from experiments reported in Nature Communications (2026), suggest that "tuning" DBS parameters may offer more refined control over complex, real-world behaviors than previously possible.
