A Mechanism Behind Protein Aggregation Discovered
September 5, 2025
Scientists have found a pathway that regulates protein aggregation, a cause of several age-related neurodegenerative diseases. United by abnormal protein aggregation Most neurodegenerative diseases are age-related, and many of them
A Potential Reason Why Clotting Increases With Age
September 25, 2025
In Aging Cell, researchers have described a method by which platelet-forming cells are rapidly generated from hematopoietic stem cells (HSCs), bypassing the intermediate cell types that are normally used to get there. Canonical and non-canonical formation It is well known that blood clots, which form when
Personalized Medicine Approach to Senolytics Clinical Trials
September 24, 2025
Recent commentary in Nature Aging summarized the results of clinical trials for senolytics and discussed recommendations for future clinical trials that use personalized medicine approaches [1]. From basic science to clinical trials Destroying senescent cells using senolytics may mitigate some aging-associated symptoms or diseases. Preclinical studies
Exercise Suppresses Appetite via a Brain Pathway
September 23, 2025
Scientists have discovered a pathway behind the known effect of exercise suppressing appetite: a lactate-related metabolite that acts directly on certain neurons. Not just more calories burned It has been long known that, somewhat counterintuitively, exercise transiently suppresses appetite. Scientists suspect that this contributes to exercise-related
