Is eternal youth scientifically plausible?

18 As the popular saying goes, the only certain things in life are death and taxes. Given its inevitability, it is no surprise that death—and the ageing process that precedes it—has fascinated humans for centuries. However, it is only with the development of modern science that we are now beginning to understand why our bodies grow older and more frail until we eventually die. As theories have ...

Towards ‘Eternal Youth’ of cardiac and skeletal muscle

INTRODUCTION The dream of eternal youth, exemplified throughout history by several examples such as the Epic of Gilgamesh in ancient Sumeria (Figure 1) in which the King of Uruk searches for a plant to restore youth, and the story of Dorian Gray in Oscar Wilde’s classical novel (Figure 2), has captured the imagination of mankind, and continues to be a major target for research. This is stimulat...

Is Noncommutative Eternal Inflation Possible?

We investigate the condition for eternal inflation to take place in the noncommutative spacetime. We find that the possibility for eternal inflation’s happening is greatly suppressed in this case. If eternal inflation can not happen in the low energy region where the noncommutativity is very weak (the UV region), it will never happen along the whole inflationary history. Based on these conclusi...

Is Double Reionization Physically Plausible?

Recent observations of z ∼ 6 quasars and the cosmic microwave background imply a complex history to cosmic reionization. Such a history requires some form of feedback to extend reionization over a long time interval, but the nature of the feedback and how rapidly it operates remain highly uncertain. Here we focus on one aspect of this complexity: which physical processes can cause the global io...
