A fountain of youth for ageing stem cells in bone marrow

As we age, our bones become thinner, we suffer fractures more often, and bone-diseases such as osteoporosis are more likely to occur. One responsible mechanism involves the impaired function of the bone-marrow stem cells, ...

Scientists reverse age-related memory loss in mice

Scientists at Cambridge and Leeds have successfully reversed age-related memory loss in mice and say their discovery could lead to the development of treatments to prevent memory loss in people as they age.

How environmental factors could provide for a young brain

A stimulating environment keeps the "hippocampus"—which is the brain's memory control center—young, so to speak. Causes of this are molecular mechanisms that affect gene regulation. These current findings from studies ...

Study reveals roadmap of muscle decline with age

Scientists have produced a comprehensive roadmap of muscle aging in mice that could be used to find treatments that prevent decline in muscle mobility and function, according to a report published today in eLife.

Study reveals neural stem cells age rapidly

In a new study published in Cell Stem Cell, a team led by USC Stem Cell scientist Michael Bonaguidi, Ph.D., demonstrates that neural stem cells—the stem cells of the nervous system—age rapidly.

Study reveals immune driver of brain aging

Suppose Smokey the Bear were to go on a tear and start setting forest fires instead of putting them out. That roughly describes the behavior of certain cells of our immune system that become increasingly irascible as we grow ...

Lumpy proteins stiffen blood vessels of the brain

Deposits of a protein called 'Medin,' which manifest in virtually all older adults, reduce the elasticity of blood vessels during aging and hence may be a risk factor for vascular dementia. Experts from the German Center ...
