Spatiotemporal clonal architecture of the newborn mouse forebrain - Nature
Clonal barcoding across the newborn mouse forebrain reveals developmental principles whereby glutamatergic neurons and astrocytes remain locally derived, whereas widely dispersed GABAergic (γ-aminobutyric acid-producing) lineages link neurons with oligodendrocyte precursor cells.

How do brightly coloured butterflies successfully evade being eaten? Fascinating new research suggests this relates to visual illusions created by their fluttering wings. The spots & stripes, combined with the dancing flight, interfere with a predator’s sense of the insects’ speed & direction. 🦋🧪
