Pill of super-protective 'heavy' fat may be key to eternal youth

Pill of super-protective 'heavy' fat may be key to eternal youth. 13 May 2015 by Jessica Hamzelou, New Scientist, Issue 3021

Mikhail Shchepinov, director of Retrotope, a biotech company based in Los Altos, California, wants eventually to slow down the ageing process. But he is starting with a related problem – treating the inherited movement disorder Friedreich's ataxia, with which ageing shares a mechanism.

The trial launching in June is a safety study. The team will be checking that the doses of heavy fat are well tolerated by 18 people with Friedreich's ataxia.
