CONCLUSION: Impaired appetite and increased inflammatory biomarkers are independently linked to mobility loss. Appetite impairment might signal early nutritional and supportive care needs, but inflammation-targeted interventions require further study.

Non-invasive recordings of brain electrophysiology provide credible insights into decline in neuronal functioning with age. New approaches are required to translate these results into compelling clinical metrics and meet the global challenge of preserving brain health in ageing. Changes in neuronal dynamics with ageing are observable in the power spectra of EEG and MEG recordings. Highly promising candidates for electrophysiological markers have been identified, but progress is hindered by...

Cells are continuously exposed to oxidative and proteotoxic stress that disrupt redox balance and protein homeostasis. Two major cytoprotective systems-the nuclear factor erythroid 2-related factor 2 (NRF2) pathway and the heat shock response (HSR) mediated by heat shock factor 1 (HSF1) and heat shock proteins (HSPs)-form an interconnected stress-adaptation network that coordinates redox defense, proteostasis, and cellular survival. Although historically viewed as largely independent pathways,...

Popular GLP-1 weight loss drugs, such as Ozempic and Wegovy, have been linked to unexpectedly high rates of nail detachment, hair loss, and scalp inflammation, with some problems occurring several times more frequently among users. Researchers found that weight loss alone could not fully explain the differences, suggesting there may be more to these overlooked symptoms.

Scientists discovered that declining levels of a protein called Menin may help drive aging, and restoring it in older mice reversed several age-related changes in just 30 days. Even more surprisingly, supplementing with a simple amino acid called D-serine improved memory and learning, offering a potential new approach to age-related cognitive decline.

Scientists have discovered that vanillin, the compound that gives vanilla its distinctive flavor, has powerful properties that could help fight infections, reduce inflammation, and promote wound healing. The inexpensive, widely available ingredient could one day become an important component of advanced wound treatments and regenerative medicine.
