Metabolism Can Shape Cells' Destinies(quantamagazine.org) A growing body of work suggests that cell metabolism — the chemical reactions that provide energy and building materials — plays a vital, overlooked role in the first steps of life.
The Role of Brown Fat and Circadian Rhythms(gethealthspan.com) Circadian rhythms regulate numerous physiological processes, including metabolism, and their disruption is increasingly linked to obesity, insulin resistance, and metabolic disorders. Concurrently, brown adipose tissue (BAT) has emerged as a key player in metabolic health, capable of burning calories through thermogenesis and significantly influencing glucose and lipid metabolism. Recent evidence indicates that BAT activity is strongly influenced by circadian timing, exhibiting diurnal fluctuations that peak in the morning.

Oligodendroglial fatty acid metabolism as a CNS energy reserve(nature.com) Brain function requires a constant supply of glucose. However, the brain has no known energy stores, except for glycogen granules in astrocytes. In the present study, we report that continuous oligodendroglial lipid metabolism provides an energy reserve in white matter tracts.
