The global challenge of population aging underscores the critical need to delay brain aging and cognitive decline, a pressing public health issue. The brain-gut-muscle axis is a complex regulatory network connecting skeletal muscle, gut microbiota, and the brain. It has received considerable research attention for its crucial role in maintaining brain health and counteracting aging. As a safe and effective non-pharmacological intervention, exercise modulates gut microbiota composition and...

INTRODUCTION: TAS2R38 is a taste receptor gene located on human chromosome 7 that influences sensitivity to bitter tastes and has been implicated in innate immunity, glucose level, and human longevity. However, its potential association with Alzheimer's Disease (AD) has not been explored. Identifying such a genetic connection could support developing new drugs or repurposing existing ones for AD treatment.

The gut microbiome influences brain function through the gut-brain axis via synthesis of neurotransmitters, production of metabolites affecting epithelial barrier integrity and immune modulation and signaling through the vagus nerve. In humans, microbiome diversity reflects healthy aging and predicts survival, while dysbiosis is increasingly implicated in neurodegenerative conditions including Alzheimer's disease, Parkinson's disease, multiple sclerosis, and ALS. Fecal transplant studies in...

CONCLUSION: Age-related changes in balance control are task dependent. Older adults preserved static balance performance but demonstrated impaired reactive balance responses in dynamic tasks. Furthermore, static and dynamic balance rely on distinct control mechanisms, highlighting the need for separate assessments.

GDF15, which is thought to contribute to nausea during pregnancy, may keep our drinking in check, researchers propose

Fabricated platforms at an Australian wastewater lagoon soak up water pollution and methane

Action cancellation - the ability to rapidly cancel an initiated movement in response to unexpected events - has been extensively studied in the upper limb using the stop signal task (SST). During gait, action cancellation is critical to stop and modify steps to avoid unexpected hazards and prevent falls. By adapting the SST to step initiation, this study investigated how the anticipatory postural adjustment (APA) and foot-lift phases of forward stepping were influenced by action-cancellation...
