The Telomerase Revolution
The Enzyme That Holds the Key to Human Aging... and Will Soon Lead to Longer, Healthier Lives
Why does growing old lead to so many forms of illness? Recent advances in the study of human cells have revealed that the key to answering this question lies in the telomeres – the tips of chromosomes – which shorten every time a cell reproduces. As he explains these insights, Fossel highlights the ability of the enzyme telomerase to re-lengthen the telomeres and discusses its potential as a means of treating age-related diseases such as Alzheimer’s.

The Hidden Rules Shaping Evolution
Professor Charles Cockell argues that evolution and natural selection have always been constrained by basic physical laws, from an atomic level to the animal realm. For instance, there are sound scientific reasons why creatures can’t evolve with wheels instead of legs, and why carbon-based cells are ideal for trapping energy, so life on Earth is far more understandable and predictable than we might imagine.
