How Cancer Begins
Every major field has its leading thinkers, and the biology of cancer is no different. What makes their impact heard better is when one of those leaders writes a book about it. Given my interest in molecular biology of cancer, I naturally have my favorite such book on the topic - Robert Weinberg’s One Renegade Cell.
Weinberg’s focus is on what he knows best: the mechanisms that promote and regulate the proliferation of normal and malignant cells. And for that, his explanations are the best out there. These explanations take up the first half of the book, corresponds to the early events in the development of a tumor, and makes up a coherent story. For example, he covers oncogenes, tumor suppressors, apoptosis, and to a lesser extent DNA repair, in relatively easy-to-follow language.

What is this thing called ‘Life?’ One popular game in the relevant area of philosophy is to provide robust counter examples, which reveal failures in operational definitions of life. Failed attempts include physiological, metabolic, biochemical, genetic and thermodynamic definitions of life, all of which face problems. For example, a metabolic definition finds it hard to exclude fire (which grows and reproduces via chemical reactions), a biochemical definition does not exclude enzymes (which are biologically functional but not living systems), while a thermodynamic definition does not exclude mineral crystals (which create and sustain local order and may reproduce).
Leading scientists in a variety of fields gave their
