For 1.5 billion years, the mitochondria - the powerhouse of the cell - have been sending DNA segments to the cell nucleus, and they merge with the DNA in the nucleus. A new study found that the contribution of the mitochondria to the DNA in the cell nucleus gradually decreases. This process is expected to reduce the incidence of some hereditary diseases

University researchers have identified a new type of organelle that has not been discovered in gametes before. According to them, a failure in its function causes infertility because it is responsible for the organization of the chromosomes in the sex cells: "The discovery advances us towards finding medical solutions"
