aging research

The rapidly growing longevity industry is expanding faster than the scientific evidence supporting its anti-ageing claims, Al Jazeera reports. Consumption of supplements, therapies and interventions marketed as life-extending is accelerating, while researchers caution that proven methods remain limited to established basics like exercise, diet and sleep. The report raises concerns about hype, cost and unproven treatments.

New research reported by ScienceDaily suggests glucosamine, a widely used joint supplement taken by millions for arthritis and cartilage health, may be associated with faster progression of Alzheimer's disease. The finding is drawing attention because the supplement has long been viewed as safe and is commonly self-prescribed, raising questions about its effects on the ageing brain.

A new Norwegian science study reports that young people aged 9 to 18 are increasingly turning to AI chatbots instead of Google for information and everyday questions. Researchers say the shift is happening quickly and its consequences for how children learn, judge sources and develop search skills are not yet understood, prompting calls for closer attention from educators and parents.

Researchers report that artificial intelligence can distinguish aged stem cells from young ones, potentially by analysing imaging data, according to an announcement carried by EurekAlert. The finding could improve understanding of how ageing affects stem cell function and support research into regenerative medicine and age-related disease.

New research reported by Medical Xpress indicates that certain dietary patterns are associated with more favorable blood biomarkers linked to biological aging. The findings suggest that what people eat may influence measurable markers of the aging process, adding to growing interest in nutrition as a tool for healthy longevity.

Researchers suggest participants' age could account for why psychedelic studies produce differing conclusions about safety and effectiveness. Older adults may respond differently to substances like psilocybin or MDMA, meaning trials skewed toward younger or older volunteers could reach inconsistent findings. The claim highlights a gap in how psychedelic research is designed and interpreted.

A new study reports that adults with higher levels of a particular vitamin showed healthier results on brain scans. The finding, highlighted by health news outlets, adds to ongoing research into how nutrition may influence brain health and could affect public guidance on diet and supplements as people age.

A new essay argues that bans on teen social media use address the wrong problem. Rather than restricting access by age, the piece suggests the focus should be on the underlying design of online platforms and how they capture attention. The debate over age limits for minors online continues to divide policymakers, parents, and researchers worldwide.

Researchers report a surprising connection between bone density and brain aging, according to a new study covered by SciTechDaily. The finding suggests skeletal health may be tied to how the brain ages, a link that could shape future research into dementia and osteoporosis. Science commentators are sharing the study, with many noting it challenges the usual separation between bone and brain research.
