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

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 ...

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

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 ...

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

Short-term IF boosts glucose homeostasis, but prolonged fasting in adolescence may impair β cell maturation—potentially linking chronic IF to type 1 diabetes risk. Study: Chronic intermittent fasting ...

Scientists have built a massive cellular atlas showing how aging reshapes the body across 21 organs. Studying nearly 7 million cells, they found that aging starts earlier than expected and unfolds in ...

Northwestern Medicine scientists have identified the cellular mechanisms that cause immune cells to differentiate and ultimately lose function during viral infection, findings that could improve ...
