Microglial cells may hold key to Alzheimer's plaque removal

Immune cells in the brain called microglia can partially break down large amyloid plaques characteristic of Alzheimer's disease by latching on to them, forming a sort of external stomach and releasing digestive enzymes into the space, according to a preclinical study by Weill Cornell Medicine investigators.

Atom probe tomography reveals fluoride patterns in aging teeth

Teeth are essential for helping people break down the food they eat and are protected by enamel, which helps them withstand the large amount of stress they experience as people chew away. Unlike other materials in the body, enamel has no way to repair damage, which means that as we age, it risks becoming weaker with time.

A new link between brain health and mitochondrial function

New findings in mice have uncovered a crucial mechanism linking neuronal activity to mitochondrial function, researchers report, revealing a potential pathway to combat age-related cognitive decline. Mitochondria play a pivotal role in meeting the dynamic energy demands of neuronal activity, producing adenosine triphosphate (ATP) primarily via oxidative phosphorylation (OXPHOS).
