Cows born without horns or pigs that never reach puberty? These scenarios could become a reality soon thanks to new gene-editing tools.
A company wants to alter farm animals by adding and subtracting genetic traits in a lab.

English scholar Thomas Malthus made his first predictions about population economics and resources in 1798. More than two centuries later, there have been many projections that the world population will eventually outstrip agricultural production.

Advances in gene editing over the past decade have given scientists new tools to tailor the biochemistry of nearly any living thing with great precision.

Gene editing is when a scientist makes a tiny, controlled change in the DNA of a living organism. The simplest way to envision this process is to imagine editing a giant manuscript.
