Scientists have discovered a cellular clue that may explain fatigue in depression and could revolutionize early diagnosis.

As the temperature drops and winter sets in, many people feel the familiar signs of the season: chilly fingers, dry skin and that sluggish sensation that can creep in during colder months. But what is ...

Depression-related fatigue is caused by cellular "overworking" at rest and a failure to produce energy under stress.

New research finds that extreme heat accelerates biological aging, especially in older adults. Living in hotter areas can age body faster.

Penn researchers Shelley Berger and Esra Sahingur explain senescence, the process of cellular aging, and discuss the complexities of developing anti-aging therapies that target these cells University ...

Exposure to fire smoke-which can be composed of particulate matter, gases, materials from buildings such as perfluoroalkyl and polyfluoroalkyl substances (PFAS), toxic metals, and carcinogenic ...

Rising temperatures disrupt human cellular stability by impairing proteostasis, altering mitochondrial function, reprogramming gene expression, and reshaping immune responses, ultimately shifting ...
