The normal ageing process has long been linked to problems with cell respiration, the process through which the cells extract energy from nutrients. Researchers at the Swedish medical university Karolinska Institutet have now shown how certain proteins that are synthesised in the cellular mitochondria – popularly known as the cells' power plants – become unstable and disintegrate, which in turn can impair cell respiration and cause premature ageing.

Scientists at the University of Liverpool have developed a new method to help researchers identify genes that can help protect the body during the ageing process.

Aging brings a sense of peace and calm, according to a new study from the Population Research Center at The University of Texas at Austin. Starting at about age 60, participants reported more feelings of ease and contentment than their younger counterparts.
