Stem cells - one of the most controversial issues of contemporary biology-cells are able to replicate indefinitely and change appearance depending on the context and the activity at any given time: the characteristics that make them very versatile, but also, in some way , invisible to the eye of the researcher. This book recounts the trials that led to the presence of the stem where it was long considered impossible: in the brain, the more static and complex element of the whole organism. The story unfolds like a real police investigation by the hour sci-fi atmosphere, now almost noir: an investigation takes place in those laboratories where researchers over the past decade, including the skepticism of the scientific community, have demonstrated the genesis of new brain cells during adult life of the individual neurons in the universe and placed it in growing stem cells, opening new perspectives in neuroscience. A book that, while it gives the flavor research and the enthusiasm of the person who carries out, on the other chooses to stick to the facts and results, without shouting match with the shades of that distribution, which ensures a quick miracle cures: the therapeutic use of cells invisible is a popular than ever promising, but the author warns, will require a long trip and still littered with uncertainties.
