A REVOLUTION IN BIOLOGY

Summary from the TLDR newsletter

This article discusses different ways in which biology can be hacked without gene editing. For example, scientists have used drug combinations to create planarians with two heads or two tails. The two-headed worms produce two-headed offspring indefinitely, meaning that the scientists achieved a permanent change in the structure of the worm - without changing its genes. Studies like this open up the possibility of a perspective shift in how the body works.
