Biohackers Edit Their Own DNA Using Basic Tools

A new technology allows people to alter their own DNA, raising questions about ethics and whether the practice should be regulated.

New Scientist reported on the use of CRISPR, a process that can change DNA and, therefore, alter human genes.

Former NASA fellow Josiah Zayner is one of the world's prominent biohackers and has altered his DNA several times. A biochemist by trade, he has injected himself with new DNA that excluded a gene that regulates muscle growth, a jellyfish protein that makes things glow, and even a concoction of a donor's DNA to help get rid of his irritable bowel syndrome.

CRISPR researcher Robin Lovell-Badge of London's Francis Crick Institute told New Scientist Zayner's homemade gene editing is "foolish" and could lead to long-term problems.
