Ageing impairs critical final egg maturation stage
Age may adversely affect women's fertility by impairing levels of RNA molecules which in turn alter the function of genes involved in key biological pathways during the final maturation stage of a human egg cell, according ...

Study finds brain's 'wiring insulation' as major factor of age-related brain deterioration
A new study led by the University of Portsmouth has identified that one of the major factors of age-related brain deterioration is the loss of a substance called myelin.

New, highly precise 'clock' can measure biological age
Using the model organism Caenorhabditis elegans, researchers at the University of Cologne have developed an 'aging clock' that reads the biological age of an organism directly from its gene expression, the transcriptome. ...

Study suggests sugary diet endangers waste-eating protein crucial to cellular repair
A protein that functions like the vintage video game Pac-Man, eating toxic cellular waste caused by high sugar intake, is itself compromised by a sugary diet, according to the results of a study in mice with potential implications ...

Senescent cells may be good when it comes to a bad injury
It's called senescence, when stressed cells can no longer divide to make new cells, and it's considered a factor in aging and in some diseases. Now scientists have some of the first evidence that at a younger age at least, ...

NSD2 enzyme appears to prevent cellular senescence
Researchers from Kumamoto University in Japan have used comprehensive genetic analysis to find that the enzyme NSD2, which is known to regulate the actions of many genes, also works to block cell aging. Their experiments ...
