Cells manage a wide range of functions in their tiny package — growing, moving, housekeeping, and so on — and most of those functions require energy. But how do cells get this energy in the first ...

Mitochondria are essential for cell survival, repair, and adaptation. Not only do they generate most of the energy needed ...

Cellular health plays a crucial role in your overall well-being. On average, the human body has between 30-40 trillion cells of various types and with various functions. The healthier your cells are, ...

Bone health relies on a balance between osteoblasts (builders) and osteoclasts (recyclers). Peak bone mass occurs in early adulthood; deficiencies during this window amplify fracture risks later in ...

A groundbreaking study published in Research (2025, DOI: 10.34133/research.0545) has elucidated the molecular mechanisms by which protein phosphatase 2A (PP2A) regulates CD8+ T cell-mediated immune ...

Since each cell has about six feet of DNA packed inside it, it must be folded up tightly to fit. This folding not only saves space -- it also controls which genes are active or inactive. But when the ...

Many biological functions are regulated by the switching on and off of mechanisms triggered by the matching of a keyhole ...

A new study describes a technique that rejuvenates aging blood-forming stem cells and could help reduce the risk of age-related blood disorders.

Other cells, such as glial cells, support the function of neurons. Neuroscience has often painted glial cells as the glue that holds neurons together, but glial cells can also be helpful in promoting ...
