Recovery of function, as a biological process, refers to the partial or complete restoration of physiological or behavioral capabilities following injury, disease, or perturbation of tissues, organs, or systems. It encompasses cellular and molecular mechanisms such as synaptic plasticity, axonal sprouting, neurogenesis, functional reorganization of neural circuits, regeneration, and compensatory recruitment of alternative pathways. This process may also involve changes in gene expression, modulation of inflammatory responses, and structural remodeling of extracellular matrices. Recovery of function is typically shaped by intrinsic regenerative capacity, environmental and rehabilitative inputs, and systemic factors such as age, hormonal status, and immune function, and is often assessed by quantitative functional outcomes.
Swallowing is a fundamental human function that supports nutrition and communication. Damage to swallowing muscles can reduce quality of life and even lead to aspiration pneumonia or malnutrition. Many patients suffer from ...

The kidney's proximal tubule reabsorbs water, glucose, ions and other small molecules from the urine and thus maintains the body's supply of these essential constituents. The tubule can be easily damaged by ischemia, or poor ...

Sometimes, in genetics, two wrongs do make a right. A research team has recently shown that two harmful genetic variants, when occurring together in a gene, can restore function—proving a decades-old hypothesis originally ...

Infertility affects about one in six couples, and male factors account for roughly half of all cases—often because sperm don't swim well. Researchers from the University of Osaka have uncovered a key component of the "switch" ...

The human body is made up mostly of water. If this water is removed, the body's cells cannot survive, even when water is reintroduced. But some organisms can completely dry out yet return to life when rehydrated.

Space changes you. It strengthens some muscles, weakens others, shifts fluids within your body, and realigns your sense of balance. NASA's Human Research Program works to understand—and sometimes even counter—those changes ...
