Scientists have discovered how the amino acid leucine boosts the body’s energy production by protecting key mitochondrial proteins from breaking down. This process allows mitochondria, the cell’s ...

Genetic engineers can design and assemble sophisticated gene circuits to program cells with new functions, but important ...

The chemical reactions on which life depends need a place to happen. That place is the cell. All the things which biology recognises as indisputably alive are either cells or conglomerations of cells ...

Prior to using this narrative, have learners create their own model of a cell in their notebooks using whatever background information or experience they might have. While exploring the narrative, ...

The microbiome-the trillions of bacteria, viruses, and fungi that live quietly in our body-plays a crucial role in shaping human health by providing a variety of micronutrients necessary for vital ...

Biomedical research typically follows a familiar path: developing treatments that block, enhance or mutate certain signaling ...

In many cells of the human body, hair-like protrusions known as cilia act as antennae, allowing cells to receive signals from ...

For much of the 20th century it was thought that the adult brain was incapable of regeneration. This view has since shifted dramatically and neurogenesis – the birth of new neurons – is now a widely ...

Scientists have built an artificial neuron that’s so realistic it fires, learns, and responds to chemical signals just like the real thing – a breakthrough that could transform computing, medicine, ...

Stem cells in most organisms typically take cues from adjacent cells. But new research from the Stowers Institute for Medical Research has found that stem cells in the freshwater planarian Schmidtea ...
