Plants and algae, meanwhile, use chloroplasts, which perform photosynthesis to generate energy from sunlight to power their cells. In a new study led by the University of Tokyo, the team inserted ...

Neurons have a "hibernation mode." Scientists discover how brain cells use RNA tentacles to lock their protein factories together to survive when energy is low.

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

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 ...

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 ...

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 ...

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 ...

(Nanowerk News) Tissue engineering seeks to repair damaged tissues by providing cellular scaffolds that support regeneration. Ideally, these scaffolds should be biocompatible, biodegradable materials ...

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