Ultrafast light pulses can manipulate and probe materials faster than relaxation timescales, leading to new electronic states and insights into equilibrium properties. Okazaki et al. use the properties of photo-induced metallic states to investigate unconventional correlated behaviour in Ta₂NiSe₅ and Ta₂NiS₅.

In the kagome superconductor CsV₃Sb₅, superconductivity is intertwined with an unconventional charge density wave and the pairing symmetry remains unclear due to the absence of direct superconducting gap measurements. Here, the authors use laser-based ultra-high-resolution angle-resolved photoemission spectroscopy to reveal a highly anisotropic superconducting gap on the Fermi surface originating from the 3d-orbital electrons of the vanadium sublattice, providing insights into the physics of intertwined orders in kagome superconductors.

Electron-phonon coupling is thought to be too weak to be responsible for the superconducting Cooper pairing of the kagome metals AV₃Sb₅, but an experimental measurement is lacking. Here, the authors use ARPES measurements to find that electron-phonon coupling in CsV₃Sb₅ is strong enough to support the experimental superconducting transition.

The superconducting gap structure of FeSe remains a debated issue. Here, Hashimoto et al. report momentum dependence of the gap in single- and multi-domain regions of orthorhombic FeSe crystals, revealing an unusual node lifting of the gap structure in multi-domain regions.

The authors report that with the use of angle-resolved photoemission spectroscopy, nodeless electron pairing in CsV₃Sb₅-derived kagome superconductors can be observed directly.

The glutamate transporter GLAST in astrocyte regulates synapse function by glutamate clearance. Here, the authors show that Down syndrome cell adhesion molecule (DSCAM) in Purkinje cells controls synaptogenesis through the intercellular association with GLAST in the developing cerebellum.

Light-matter interactions can be used to induce a superconducting-like state in some cuprate superconductors at temperatures above the expected transition temperature. Here, the authors provide time and angle resolved spectroscopic evidence to suggest that photo induced superconductivity can also be achieved in Fe-based superconductors

Multiple different types of topological states are observed in iron-based high-temperature superconductors. This suggests that these may be a good place to try and engineer high-temperature topological superconductivity.

DISC1 is believed to be a genetic risk factor for schizophrenia, but its pathophysiological functions are not fully understood. Using proteomics, Tsuboi et al. identify several RNA-binding proteins, including HZF, as DISC1 interactors and reveal that DISC1, together with HZF, regulates the dendritic transport of ITPR1 mRNA to modulate synaptic plasticity.

Glutamate transporters mediate neurotransmitter reuptake at glutamatergic synapses. Here the authors show that CDC42 effector protein CDC42EP4 supports efficient glutamate clearance by promoting the tethering of a glutamate transporter GLAST to perisynaptic clusters of septins in Bergmann glia.

Kagome systems are a rich playground to explore the interplay between superconductivity and charge order. Here, the authors present a comprehensive muon spin rotation analysis, coupled with scanning tunnelling microscopy, under various tuning parameters including chemical doping, depth and hydrostatic pressure to investigate time-reversal symmetry-breaking in Nb-doped CsV₃Sb₅.

The authors show that shortening of the basal process in neural progenitor cells by depletion of TAG-1 results in overcrowding in the periventricular space and, eventually, delamination and aberrant migration. These results suggest that one of the functions of interkinetic nuclear migration is to prevent progenitor congestion and mechanical stress.
