The effect of medicines on women and men can differ significantly. This also applies to the currently most promising anti-aging drug rapamycin, as researchers from the Max Planck Institute for Biology of Ageing in Cologne and University College London have now shown. They report in Nature Aging that the drug only prolongs the lifespan of female fruit flies, but not that of males.

In addition, rapamycin only slowed the development of age-related pathological changes in the gut in female flies. The researchers conclude that the biological sex is a crucial factor in the effectiveness of anti-aging drugs.

The life expectancy of women is significantly higher than that of men...

In new research, Aric N. Rogers, Ph.D., who studies the cellular and molecular mechanisms of aging at the MDI Biological Laboratory in Bar Harbor, Maine, has discovered that muscle may be a protected tissue under conditions of dietary restriction, or DR.

Dietary restriction, in which calories are restricted without malnutrition, is one of the most robust anti-aging interventions. When confronted with a scarcity of nutrients, an organism conserves resources by lowering the translation, or production, of proteins, which is one of the most energetically expensive processes in the cell. Proteins serve as the building blocks for tissues and organs and perform vital physiological functions.

The conservation of cellular resources through red...

Bochkis, Ph.D., of the University of Virginia School of Medicine, has made a new discovery that could let us prevent or cure diseases such as diabetes and fatty liver disease — and possibly let us turn back the clock on aging itself.

How would we do it? By using viruses as tiny aestheticians. A new discovery about the effects of aging in our cells could allow doctors to cure or prevent diabetes, fatty liver disease and other metabolic diseases – and possibly even turn back the clock on aging itself. The new finding from the University of Virginia School of Medicine suggests that fatty liver disease and other unwanted effects of aging may be the result of our cells’ nuclei getting wrinkly...
