Can research into a rare, accelerated aging disease and "zombie cells" teach us something about the normal aging process? Did you know that a small molecule called NAD + plays a critical role in our ...

It has long been known that a hallmark of Alzheimer's disease, and most other neurodegenerative diseases, is the clumping together of insoluble protein aggregates in the brain. During normal ...

Growing older affects every part of the body, including the brain. Many people notice changes in memory, concentration, and mental sharpness as they age. Scientists have long known that aging ...

Mesenchymal drift may help explain how cells lose stable identity and acquire pro-fibrotic, inflammatory mesenchymal traits ...

An international research team has uncovered new insights into healthy brain aging. The researchers found that aging leads to the accumulation of defective energy molecules in the brains of aged mice, ...

I’m afraid I might be getting Alzheimer’s. How do I know if I’m developing it? Once every few weeks, I forget where I put my phone. Or I walk into a room to get something, and then suddenly wonder ...

While chronological age is easily measured, it fails to capture the complex biological processes that determine the rate of aging. A new proteomic aging clock may predict biological age, mortality ...

It could be as simple as constantly misplacing keys, or forgetting to pay a bill, or repeating questions over and over. As people age, their memory and cognition tends to take a small hit. But about ...

Aging is a natural part of life, and most of us expect to see signs of aging in our 50s and 60s, such as wrinkles, gray hair, and slower metabolism. However, some people seem to age much faster than ...

To date, approaches to treatments for Alzheimer's disease have not addressed the contribution of protein insolubility as a general phenomenon, instead focusing on one or two insoluble proteins.
