Mouse epigenetic aging clock uncovered

Ageing in humans (and animals) can be seen as either an inevitable process of wear and tear or as an inherent biological programme by which the lifespan of each species is more or less predetermined. Recent research has shown ...

Dieting causes epigenetic changes during ageing

Reduced food consumption extends the lifespan of many organisms, including primates. The biology behind how this is achieved, however, is not yet fully understood. Researchers at the Max Planck Institute for Biology of Ageing ...

Pinpoint creation of chirality by organic catalysts

Researchers at Nagoya University have reported in Nature Communications on the development of an organic catalyst (organocatalyst) that triggers a highly stereoselective 1,6-addition of azlactones (nucleophile) to a δ-aryl ...

What happens in the cell nucleus after fertilization

A team of scientists at the Helmholtz Zentrum München shows changes in the immediate environment of DNA after the ovum and sperm fuse to form the zygote. The results suggest why all conceivable somatic cells can develop ...

DNA methylation affects superiority of hybrid plants

Hybrid vigor refers to when a crossbreed plant or animal shows superior traits compared to its parents. A research group has discovered that a gene involved in maintaining DNA methylation is closely connected to hybrid vigor ...
