biological age research

A new study explains how the loss of genetic material on the Y chromosome may drive cancer development in men. Researchers say age-related loss of parts of the Y chromosome can impair tumour suppression, potentially explaining why certain cancers affect men more severely. The findings could point to new biomarkers and treatment approaches.

New research suggests donor hearts may take on the biological age of their recipients after transplantation, rather than retaining the age of the original donor. Reported by Scientific American, the finding could reshape how doctors think about organ aging, rejection risk and long-term outcomes for transplant patients.
