GlaxoSmithKline's top scientist joins Jeff Bezos-backed anti-ageing start-up Altos Labs

The top scientist at GlaxoSmithKline will leave the pharma giant to help lead a start-up founded by a cadre of billionaires who seek immortality.

Hal Barron, 59, announced he will jump ship to run the Silicon Valley venture Altos Labs, which is focused on anti-aging technology. 

Billionaires including Amazon founder Jeff Bezos and Russian venture capitalist Yuri Milner are funding the biotechnology firm with the aim of discovering a way to reverse aging.

Barron will step down as chief scientific officer in August to become chief executive and co-chairman of Altos Labs.
