Scientist edit his own DNA to get boosted strength and muscle growth

Josiah Zayner, a biochemist, and former NASA worker has become the first person known to have edited his DNA after removing a protein which inhibits muscle growth

Rogue scientists are editing their own genes in a bid to make ­themselves superhuman, with boosted strength and senses.

Biochemist Josiah Zayner has become the first person known to have edited his DNA with the CRISPR tool.

The ex- NASA worker removed myostatin, which inhibits muscle growth, with the gene-cutting technology. He said: “This is the first time in history that we are no longer slaves to our genetics.”

Such technology is highly regulated in the US and UK, but it is not illegal to edit your own DNA. Mr. Zayner, whose firm sells DIY gene-editing kits, live-streamed himself injecting the modified copy of his DNA.

He initially expects to see extra muscle growth in that arm. Another US “biohacker” plans to insert a genetic mutation that lets humans see in the ultraviolet spectrum.

London-based CRISPR researcher Robin Lovell-Badge warned of adv­­erse reactions. But University of Manch­ester bioethicist John Harris said: “There’s a long history of scientists experimenting on themselves.”
