L'età genetica: La rischiosa ambizione di modificare la vita

by Matthew Cobb, Silvio Ferraresi (translator)

La storia lunga mezzo secolo di una rivoluzione scientifica e tecnologica che ha mutato per sempre la nostra visione della vita. Un saggio che illustra il sorprendente potenziale di cambiamento del mondo offerto dall'ingegneria genetica ma anche le inquietanti minacce di cui è portatrice.


Negli ultimi cinquant'anni, una rivoluzione scientifica e tecnologica ha trasformato il nostro mondo, permettendoci di guarire da alcune malattie e mettendo piú cibo sulle nostre tavole. Da quando la scienza può manipolare con estrema precisione i geni di praticamente qualsiasi organismo, l'umanità ha guadagnato un grado di controllo sulla vita che nemmeno la fantascienza si era mai sognata. L'età genetica è la storia di questa rivoluzione, degli entusiasmi ma anche dei pericoli e delle proteste che ha provocato, di come ha modellato la nostra cultura, trasformando la nostra visione della vita stessa. Nei momenti chiave della storia della genetica (dalla scoperta della doppia elica all'avvento delle colture Ogm), alle promesse di una nuova fonte di cibo o di cure decisive di alcune gravi patologie hanno fatto seguito timori di pestilenze, di esseri umani geneticamente manipolati o di guerre biologiche. Paure che non si sono mai materializzate, ma che ciclicamente ritornano. Matthew Cobb esamina le fantasie e la realtà, i benefici e i pericoli, per dare evidenza a tutte le potenzialità dell'età genetica. Con gli ultimi sviluppi di «editing» con il Crispr, la manipolazione genetica in funzione ecologica e la modificazione di virus letali siamo ancora una volta di fronte a un momento cruciale di un futuro che è quasi impossibile immaginare, un futuro troppo importante per essere lasciato in mano ai soli scienziati.

This book changed the way I think about science. I learnt about these techniques in my undergrad without ever thinking of them as anything more than a means to an end. But my eyes have been opened to the real need to think about the ethical considerations of such advancements and experiments and whether we should ask ourselves,’just because we can, does it mean that we should?’

[judy · Rating 4 out of 5]

a full insight into the genetic engineering world and its history, posing very important ethical questions

I rather enjoyed this read. (only nonfiction I can ever read is on this topic)

[Fliss · Rating 4 out of 5]

it took me a long old time to read this because it was too related to my academic work for me to want to read it in my downtime once term had begun, and not essential enough to my work that i felt justified reading it in my studying time, so i only read it partially at the end of summer break and then partially in the winter break. and i read nothing else in the meantime which was a bit silly of me!

but besides these circumstances, i did enjoy this book i think. it was readable and had a clear overall narrative and clear messages that the author wishes you to ponder but i didn't feel like he instructed too much on what you ought to think. but then again I speak as a biochemistry student who has studied quite a lot of genetics and molecular biology and generally has a pro-genetic-engineering attitude. that also means I can't speak for how understandable this book is for someone without prior subject familiarity - i think it did explain everything but I didn't need to digest those explanations carefully like I imagine you would need to otherwise.

also btw I actually finished this on the 3rd january 2025 but i want it to count to 2024 not 2025

Obviously it helps when the subject matter is fascinating to begin with, but Matthew Cobb's natural and animated writing style makes for a fast-paced and absorbing narrative history of genetic engineering, its characters and its controversies. I'd just make a couple of observations.

Firstly, be aware that this is very much a polemic. The author is enthusiastic about the subject, but deeply - and understandably - hostile to certain research directions (notably human-heritable gene editing, gene drives and gain-of-function research). This isn't a problem of course, unless you were expecting a neutral exposition.

Secondly, as someone with no background in biological sciences I found the cursory explanation of the 'basics of genetics' in the introduction to be very inadequate. Having finished the book, I still have big gaps in understanding (I'm none the wiser about how somatic gene edits actually propagate, for example). The author occasionally drops in technical words without explaining them, presumably because they're so familiar to him. There's a helpful glossary squeezed between the Acknowledgements and the Notes, and I'd recommend parking a bookmark there.

An authoritative and thorough account of genetic engineering from its advent up until the present day (2021).

Matthew Cobb is detailed in his account, not only of the science, but of the ethic surrounding it and its impact. I’m not sure how digestible it would be for someone who doesn’t have a scientific background, but I found it fascinating.
