They Can Be can be absorbed the layperson interspersed with a level of anecdotes that keep it flowing an agreeable rate without it becoming a tome of personal triumph or vehicle for misplaced humour as is often the case with less iligent science authors For such an interesting topic reading this book really felt like a chore sometimes The author jumped from one topic to another a lot had too many unnecessary etails and Renaissance Emerge Series dates and the overall writing style just wasn t engaging enough in my opinion I still found some chapters uite interesting so 3 stars Since I m in the middle of my female authors only month I thought now would be a good time to get round to some of the non fiction books I have by women especially in the STEM field I forgotten I had this one which is a shame it fits into my general theme of reading about neurology and builds on a lot of the stuff about ion channels that I learnt in an introductory biology class on Coursera I understood pretty much all the science without wanting or needing to look anything up or letting anything wash over my head in part that s because Ashcroft writes very accessibly but I think it is also because this is stuff I know and loveSome of it is a little too much towards the neurology end of things for me I wanted about electricity in the human body of the sparks and less of the chemical messages the soups in that old scientific Guantanamo and the Abuse of Presidential Power debate this veered towards talking much about the chemical parts of the process es I think most of us are aware that the human body uses both chemical and electrical signalling to control its inner functions but until I read this book I had certainly never realised that extent to which a rather strange electrical process strange because it involves the flow not of electrons as in normal electricity but of ions is handled by ion channelsAfter a preface that is a little confusing as she uses terms that aren t really explained until later biologist Frances Ashcroft who spends herays working with ion channels gives us a brief introduction to electricity This physics part is by far the weakest bit of the book For example she From a Whisper to a Shout doesn tifferentiate between a flow of electrons and the electromagnetic signal in a wire and some of the history is a little out of Alt 10 Retrospect Prospect date she says for instance that Franklinid the kite in a thunderstorm experiment which is thought unlikely now But this is only an introductory phase before we get into the meat of the book which is uite fascinatingAshcroft explains how ion channels can open and close to allow a flow of ions through and how electrical energy is involved in making these essential cell components function This is absolutely fascinating from the first mention of sodium pumps I was hoping to come across the medication type proton pump inhibitors which like many thousands of people I take but if they were mentioned I missed it It is remarkable how this essential part of cell function wasn t properly understood until around 50 years agoFor the rest of the book we are taken on a tour of the body and the way that ion channels have a powerful influence on everything from poisoning to the functioning of memory It is uite mind boggling just how much these tiny channels Integrating African American Literature in the Library and Classroom do for us alwaysependent on that electrical motive powerFor me and it is fair to say that my biology tolerance is pretty low the book id get a little repetitious in some ways if only because of the central role of ion channels throughout I suspect though for many the connection with the functioning of the human body will keep that interest going and Ashcroft has a light approachable tone and makes sufficient ventures into the wider picture to keep the reader on board Overall a subject that clearly needed writing about carefully and entertainingly revealedReview first published on wwwpopularsciencecouk and reproduced with permission This book is life altering and paradigm changing If you ve not been amazed by your own body just yet firstshame on you and second buy this book and keep it as a national treasure The overall content of the book is about how electricity is generated in our amazing bodies All of our thousands of cells contain potassium and outside of the cell is highly concentrated with sodium Within all of our cells we have these amazing things called ion channels that are innervated by a multitude of things and they open and close letting sodium in and potassium out This very act of exchanging within the protein of the ion channels is the very thing that innervates us We literally are the body electric We re amazing These ion channels are literally responsible for everything If you have a efective ion channel you could have an ailment that you already know about but little Reading Contemporary African American Literature did you know that the ailment isue to ion channels Everything our senses our brains our emotions personality behavior all boils Southern African Literature: An Introduction down to ion channels It literally moves me to tears I highly recommend this book When I get accepted into the PhD program I want guess what myissertation will be on Ht on conditions ranging from iabetes and allergies to cystic fibrosis migraines and male infertility With inimitable wit and a clear fresh voice award winning researcher Frances Ashcroft weaves together compelling real life stories with the latest scientific findings giving us a spectacular account of the body electr. ,

This was not a fast read but uite understandable to the educated layperson I learned a great eal from the AC or DC wars of Edison and Tesla to the ways ion channels which are proteins control whether and when certain ions pass into or out of the cells causing electrical currents throughout the neurons causing muscles to contract and glands to secrete or not The history of the Plowshares Pork Barrels: The Political Economy of Agriculture (Independent Studies in Political Economy) discovery of electricity was great and the means by which it has been used for good or ill to treat manyifferent maladies was a very interesting aspect of the bookThe fact that the ion
