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

Researchers have transplanted healthy mitochondria into brain cells and animal models of neurodegeneration, reporting improved energy output, reduced cell death, and temporary recovery of motor ...

Tissue optical clearing is a fundamental technique that enhances light penetration deep into biological samples by reducing light scattering through refractive index homogenization. This process ...

A key question that remains in biology and biophysics is how three-dimensional tissue shapes emerge during animal development. Research teams have now found a mechanism by which tissues can be ...

In cell culture experiments, stem cells from human baby teeth promoted neural cell proliferation. In rat models, the stem cell therapy improved motor skills and learning, suggesting potential ...

Ribosomes, the cell's protein-making factories, consume large amounts of energy as they build the proteins that keep cells alive and functioning. When cells experience stress—such as lack of nutrients ...

Animals display an extraordinary array of structural adaptations that are intimately linked to their functional capacities. From the microscopic organisation of tissues and cells to the macroscopic ...

Biomedical engineers are now able to take a live, holistic look at the inner workings of a small animal with enough resolution to see active organs, flowing blood, circulating melanoma cells and ...

Persistent organic pollutants (POPs) begin to accumulate in the tissues of mammals already during the fetal stage, according to new research from the University of Oulu, Finland. The animal-model ...

A single genetic “switch” may be the secret to how the body’s cleanup crew grows up and keeps our organs running smoothly.

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 ...
