Mitochondria and health

NIHJuly 22, 2025

Your cells’ mitochondria produce almost all the energy your body needs to survive. They also play a role in many other vital cellular functions. This Research in Context feature looks at how insights about these cellular powerhouses might lead to new ways of preventing and treating disease.

Scientists Develop High-Performance MRI Scanner in Effort to Define Microscopic Brain Structures

NIHJuly 16, 2025

Next-generation system noninvasively images tiny nerve structures disrupted in brain disorders.

Engineering immune cells within the body

NIHJuly 15, 2025

Scientists developed a way to engineer T cells within a living organism. The approach could make CAR T cell therapies more accessible for treating cancer and autoimmune diseases.

Measuring aging with brain scans

NIHJuly 15, 2025

Researchers developed a way to measure how fast a person is aging from a single brain scan. The findings may aid efforts to predict a person’s risk for age-related diseases and test interventions to slow aging.

How exercise can protect against Alzheimer’s

NIHJuly 1, 2025

Researchers used a mouse model to gain insights into how exercise alters brain cells to protect them against Alzheimer’s disease. The findings hint at possible future treatment strategies.

Exercising With Chronic Conditions

NIHJune 10, 2025

Almost anyone, at any age, can do some type of physical activity, even with a chronic condition. In fact, older adults with chronic conditions can benefit from physical activity.

Keep AMD Vision Loss In Check

Memory Problems, Forgetfulness, and Aging

NIHMay 29, 2025

Older adults may worry about their memory and other thinking abilities, such as taking longer to learn something new. These changes are usually signs of mild forgetfulness — or age-related forgetfulness — and are often a normal part of aging.

Scientists design gene delivery systems for cells in the brain and spinal cord

NIHMay 21, 2025

Research teams funded by the National Institutes of Health (NIH) have created a versatile set of gene delivery systems that can reach different neural cell types in the human brain and spinal cord with exceptional accuracy. These delivery systems are a significant step toward future precise gene therapy to the brain that could safely control […]
