This month, a group of researchers published an annual report on the clinical trials that are testing drugs for Alzheimer’s disease. Overall, they reported an increase in the number of trials, with 158 drugs investigated across 192 trials [1]. A growing problem The projections regarding the prevalence of Alzheimer’s disease are merciless. While in 2017,...

A recent study found an association between longer and more frequent daytime napping and higher mortality risk. The authors suggest using napping frequency and duration as behavioral markers of increased mortality risk [1]. Common activity with a dark side Daytime napping is a relatively common activity among older adults. It is estimated that between 20%...

An investigation into the aging immune system identified age-related changes, including sex-dependent differences, in immune cell subpopulations and gene expression. In general, females showed greater age-related changes than males, including greater changes in autoimmune gene expression [1]. Cell-by-cell analysis Aging results in changes to the function and composition of immune cells, collectively referred to as...

A recent study described a process called ferro-aging, in which iron accumulation leads to oxidative damage and cellular senescence. This process can be delayed by Vitamin C [1]. A two-faced atom Iron, like many components of biological systems, has two faces. On the one hand, it’s essential for developmental and metabolic processes [2, 3]. On...

A recent study investigated a connection between the timing of meals and the rate of biological aging. These findings suggest that later timing of the first and last meals is associated with faster aging [1]. Finding the right patterns and rhythms Chrono-nutrition is an approach that connects eating patterns, circadian rhythms, and health outcomes [2]....

A recent study suggests that the transition of king penguins from the wild to a zoo environment, which resembles a sedentary, well-fed Western lifestyle, results in accelerated aging and changes in metabolic pathways [1]. A unique model system A sedentary lifestyle and obesity are linked to accelerated aging in humans and, at the molecular level,...
