Scientists have reversed ageing in mice

Scientists have partially reversed the ageing process in mice using genetic engineering. These mice showed signs of new growth of the brain and testes, improved fertility, and the return of a lost cognitive function. Scientists from Harvard and the University of New South Wales are working on the various aspects of the study. They are of the opinion that a major breakthrough in the research will help develop drugs that will restore youthfulness in human cells.

How much skin do humans shed?

Our skin is made of many layers of cells. The outer layer is flaky and the inner layers have structure giving and nourishing elements. The outer skin gets dry or damaged with time and so it gets shed. An average person sheds about 30,000 cells every minute and about 18 kilograms of skin in his or her lifetime. Most household dust is made of dead skin.
