Graphene antidot measures anyonic charge
Researchers have used a gate-defined antidot in bilayer graphene to measure the fractional charge of anyons, quasiparticles key to future topological

Erk Gradients Control Zebrafish Fin
Researchers have identified how zebrafish fins regenerate to their exact pre-injury size. A study in *Nature Physics* shows that gradients of Erk activity, established by the Fgf20a ligand, encode positional memory and predict the final length of regenerated bone.

Twisted MoS2 Reveals Exciton Localization
Scientists imaged moiré-confined excitons in a 2° twisted bilayer MoS2 with nanometre resolution using room-temperature photocurrent atomic force microscopy. The study shows that direct and indirect excitons localise at different stacking registries within the moiré lattice.
