The Poison Factory
Researchers have traced the six-enzyme assembly line wolfsbane and larkspur use to build atisinium, a toxin now being explored for pain, malaria, and cancer, and then run that same line inside tobacco plants. Aconitine, its close relative, was isolated in 1834 and has never been synthesized in a lab; the instructions were in the genome the whole time, waiting for someone to read them in order.

Sixteen Percent
Ten herbaria hold an estimated 16.5% of the world's plant specimens. Here's where — and why it matters.
