Low-intensity brain stimulation may restore neuron health in Alzheimer’s disease

Alzheimer’s disease (AD) is a debilitating neurodegenerative condition that affects a significant proportion of older people worldwide. Synapses are points of communication between neural cells that are malleable to change based on our experiences. By adding, removing, strengthening, or weakening synaptic contacts, our brain encodes new events or forgets previous ones.

A new model enables drug discovery for a disorder affecting 40 people worldwide

Researchers at the Gray Faculty of Medical and Health Sciences at Tel Aviv University have developed a model that accurately replicates an extremely rare and sometimes fatal genetic disorder caused by a mutation in the GRIN2D gene. This mouse model allows the research team to study the disease’s characteristics and test a variety of drugs and genetic therapies, offering hope to affected children and their families.

Aging-related inflammation is not universal across human populations, new study finds

Inflammation, long considered a hallmark of aging, may not be a universal human experience, according to a new study from Columbia University Mailman School of Public Health.
