Longevity
In search of forever
Slowing, let alone reversing, the process of ageing was once alchemical fantasy. Now it is a subject of serious research and investment, Geoffrey Carr reports

In search of forever
Slowing human ageing is now the subject of serious research
And some of it is making progress, writes Geoffrey Carr
Don’t be greedy
Eating fewer calories can ward off ageing
And various existing medicines may offer similar benefits
Out with the old
Ageing bodies need to get rid of decrepit cells
Senolytics and cellular rejuvenation could hold the key
Of bowheads and borzois
Alternatives to the laboratory mouse
Researchers are looking at whales, sparrows and large dogs
Give us the tools
Fighting ageing requires properly equipped cells
Keeping the right proteins in the right amounts
A design for living
Some claim human lifespans can be lengthened indefinitely
Why not try a “country club for precision diagnostics” while you wait?
