A wave of lawsuits will push juries to decide on an issue that researchers are still debating.

Aluminium redox catalysis is achieved with a low-valent aluminium species, carbazolylaluminylene, enabling cyclotrimerization of alkynes and producing diverse benzene derivatives.

An orthosteric CSN inhibitor gains nanomolar potency via a molecular-glue mechanism, stabilizing a CSN5–N8–inhibitor complex that confers substrate-dependent inhibition despite weak free-enzyme affinity.

An outbreak of MPXV in sooty mangabeys in Côte d’Ivoire was linked to MPXV-infected fire-footed rope squirrels, providing direct evidence of interspecies transmission and indicating risk for zoonotic transmission of MPXV from both hosts.

A strategy using simple one-step spin-coating to form 3D/2D vertically oriented perovskite heterojunctions is described, allowing the fabrication of perovskite light-emitting diodes with record-high green emission efficiencies of 42.9% (certified 42.3%).
