Borrowed Time: The Science of How and Why We Age

by Sue Armstrong

Overview

V etoj knige nauchnyj zhurnalist S'yu Armstrong dostupnym yazykom rasskazyvaet o razvitii gerontologii — nauki o starenii i o tom, kak prodlit' molodost'. Eto ne suhoe izlozhenie teorij, a personalizirovannaya istoriya, rezul'tat mnozhestva nauchnyh komandirovok i interv'yu, kotorye avtor vzyala u samyh avtoritetnyh sovremennyh uchenyh v etoj oblasti. Teoriya svobodnyh radikalov, kletochnoe starenie, telomery, stvolovye kletki, genetika i epigenetika, immunnaya sistema, vozdejstvie ekologii i rezhima pitaniya, bolezn' Al'cgejmera i drugie vozrastnye izmeneniya mozga — lish' nebol'shaya chast' togo, v chem pomogaet razobrat'sya Armstrong. "Vopros o tom, zachem i pochemu zhivym sushchestvam (osobenno nam) prihoditsya staret', volnoval uchenyh stoletiyami, a do edinogo mneniya vse tak zhe daleko. Vydvinuta massa konkuriruyushchih teorij: ot vstroennyh mekhanizmov samorazrusheniya i idei, chto starenie — eto obyknovennyj iznos tela vrode rzhavleniya avtomobilya ili porchi palatki, kotoraya mnogo let prostoyala pod dozhdem i vetrom, do teorii telomer, kotorye (tik-tak, tik-tak…) otmechayut otpushchennyj nashim kletkam srok, stanovyas' vse koroche i koroche. Est' takzhe mnenie, chto starenie i smert' zaprogrammirovany i upravlyayutsya na geneticheskom urovne. Vse bol'she uvazhaemyh uchenyh sklonyayutsya k mysli, chto starenie – bolezn', podlezhashchaya terapevticheskomu kontrolyu. Nekotorye zahodyat eshche dal'she i schitayut, chto ot stareniya mozhno vylechit' sovsem – i tem samym otkryt' i nashemu vidu dorogu k vechnoj zhizni". (S'yu Armstrong)

About the Author

Sue Armstrong is a science writer and broadcaster based in Edinburgh. She has worked for a variety of media organisations, including New Scientist, and since the 1980s has undertaken regular assignments for the World Health Organization (WHO) and UNAIDS, writing about women's health issues and the AIDS pandemic, among many other topics, and reporting from the frontline in countries as diverse as Haiti, Papua New Guinea, Uganda, Thailand, Namibia and Serbia. Sue has been involved, as presenter, writer and researcher, in several major documentaries for BBC Radio 4; programmes have focused on the biology of ageing, and of drug addiction, alcoholism, obesity, AIDS, CJD, cancer and stress. Her book p53: The Gene that Cracked the Cancer Code, also published with Bloomsbury Sigma, was highly commended by the BMA Book Award.

Editorial Reviews

12/03/2018
Science writer Armstrong (P53: The Gene That Cracked the Cancer Code) illuminatingly surveys research into aging’s biological mechanisms, beginning by revealing that, perhaps startlingly for laypeople, “a growing number of respected scientists... believe that ageing is a disease, and it can be treated.” Armstrong discusses sources of aging on the cellular level, including free radicals, the degradation of telomeres, and cell senescence, noting that none has yet provided the key to “solving” aging. Armstrong devotes much space to one of the most fearsome age-related disorder of all, dementia, discussing attempts to understand and combat Alzheimer’s and similar dysfunctions. Along the way, she profiles a number of fascinating people, leavening the somewhat dense science with human interest, such as leading Alzheimer’s researchers Caleb Finch and Eric Davidson and their time spent collecting traditional music from Appalachia for the Library of Congress. Armstrong also discusses promising possible dementia treatments, including rapamycin, induced pluripotent stem cells, and, possibly most exciting of all, a new application for the common diabetes drug metformin. Without suggesting death can actually be stopped, Armstrong’s work shows that quality of life before the inevitable might very well be significantly improved. (Feb.)

Publishers Weekly

Invigorating.” —Booklist

“As a seventy-five-year-old man I felt oddly rejuvenated by this book. Try it yourself!” —Professor Steve Jones

“Sue Armstrong's book humanely tackles ageing in a way that is grounded, philosophical and makes the most complex science accessible to lay people like me. While not dangling false hopes of innovatory medical cures, it is full of hope about the strides being made in gerontology and pharmacology. And while I may be getting older, the vigour of this book is life-enhancing.” —Claire Fox, Director of the Academy of Ideas and panellist on BBC Radio 4's The Moral Maze

“Authoritative, comprehensible and fun to read. The book ageing research has been waiting for.” —Richard Faragher, Professor of Biogerontology at the University of Brighton

“Borrowed Time gives a wonderful overview of the fast-evolving science of longevity. I thoroughly recommend this book as a primer on what will become a key industry in the next two decades or so.” —Jim Mellon, Chairman, Juvenescence Ltd.

From the Publisher

Winter 2018

Science journalist Armstrong (P53: The Gene That Cracked the Cancer Code) presents the state of current research on aging, beginning with the universal hallmarks of getting older—problems that develop with genes and their expression, proteins, nutrient processing, mitochondria, stem cells, and inflammation—and shows how scientists are exploring each in hopes of discovering ways to slow or reverse the aging process. While there are many promising laboratory models for achieving this, most cannot yet be tested on humans. Prescription drugs already on the market for use in other conditions have also demonstrated promise in ameliorating some of these effects in some human patients. Armstrong devotes several chapters to the efforts underway to understand and treat Alzheimer's disease, one of the most feared aspects of aging. VERDICT Armstrong uses an informal style to explain complicated research in lay-friendly terms. Her book will be of interest to everyone who hopes to live a long, healthy life.—Rachel Owens, Daytona State Coll. Lib., FL
