A hidden connection delivers energy directly from mitochondria to the nucleus, helping cells mature and embryos develop ...

An international research team has provided a detailed insight into how the spatial organization of genetic material is established in the cell nucleus of early embryos within the first hours after ...

For decades, biologists assumed a cell's energy simply diffused to wherever it was needed. It turns out the most important ...

The genetic code is the recipe for life, and provides the instructions for how to make proteins, generally using just 20 amino acids. But certain groups of microbes have an expanded genetic code, in ...

To overcome the inherent challenge of translation termination interference caused by stop codon reprogramming in mammalian cells, researchers from Peking University led by Chen Peng from College of ...

Reduced mitochondrial activity during development triggers a specific superoxide signal that downregulates the biosynthesis of unsaturated fatty acids. This metabolic shift limits lipid peroxidation, ...
