Molecular Interaction Guides Neurons in Developing Brain
In this journal cover design, three molecules (Teneurin-Latrophilin-FLRT, foreground) interact between radial glial cells and neurons (green and blue, background) in the developing brain to ensure the neurons migrate correctly. The bright region where the molecules interact is better understood than the darker regions.
This 1.5 page spread for Scientific American illustrates the relationship of DNA to chromatin, the density of chromatin packing in the nucleus, and schematically show how chromatin loops are formed that both prevent entanglement and allow for gene regulation.

Deoxyribonucleic acid, DNA, shown in three three-dimensional (3D) styles: surface, ball and stick, and stylized Bohr’s atoms. Line drawings of the individual bases (Adenine, thymine, guanine, and cytosine) are shown in the background.
The prevailing theory of nerve signal propagation holds that signals are transmitted via depolarization of membrane potential. This involves voltage gated ion channels and cross-membrane ion movement (top left inset).
A more recent theory of nerve signaling (the Heimburg model) describes the signal instead as a physical wave through the axon membrane (bottom right inset).
