Reproductive Ageing: Unlocking the secrets of reproductive longevity: the potential of social insects.

In Brief: Social insect queens display both extraordinary longevity and fertility. In this point of view, we describe their distinctive traits that make them useful models for reproductive longevity, holding implications for human health discoveries.

Abstract: Social insects present an extraordinary opportunity as models for reproductive longevity because they challenge the conventional patterns of aging and reproduction seen in other model organisms.

Exercise Induces White Adipose Tissue Browning Across the Weight Spectrum in Humans.

While the effect of exercise on white adipose tissue browning and metabolic improvement in rodents is clear, there are few studies in humans with inconclusive results. Thus, the aim of the study was to assess whether an exercise intervention promotes subcutaneous adipose tissue browning in humans, and whether this response is associated with metabolic improvement in three groups of individuals defined by body mass index (BMI) (kg/m). Sedentary adult subjects with different BMI were enrolled in a 12-week bicycle-training program (3 times per week, intensity 70-80% HRmax).
