In a groundbreaking study published on October 23, 2025, scientists have successfully reversed brain aging and memory loss in mice. This achievement was made possible through innovative techniques ...

Cedars-Sinai researchers created “young” immune cells from human stem cells that reversed cognitive decline and Alzheimer’s symptoms in mice. The treated animals showed better memory and healthier ...

Anxiety disorders are some of the most common mental health conditions in America, affecting about one in five people nationwide. But much remains unknown about the roots of anxiety in the brain. Now, ...

Scientists at Stanford have found that hyperactivity in the brain’s reticular thalamic nucleus may drive autism-like behaviors. In mouse models, drugs and neuromodulation techniques that suppressed ...

Visualization of 75,000 neurons (colored dots) active across the brain of an adult mouse across different stages of a decision-making task. Dot size reflects a cell’s average firing rate, such that ...

Cedars-Sinai researchers created “young” immune cells from human stem cells that reversed signs of aging and Alzheimer’s disease in mice. The treatment improved memory, preserved mossy cells in the ...

When young donor myeloid cells are transplanted into aging mouse brains, they quickly adopt aging phenotypes. In contrast, old myeloid cells transplanted in young brains take on a more youthful aspect ...
