We describe an imidodiphosphorimidate-catalysed asymmetric Wagner–Meerwein shift of aliphatic alkenyl cycloalkanes to cycloalkenes with excellent regio- and enantioselectivity.

Evidence for a quantum magnetic analogue of a supersolid appears in a recently synthesized antiferromagnet showing a strong magnetocaloric effect of the spin supersolid phase with potential for applications in sub-kelvin refrigeration.

tRNA display enables the direct selection of orthogonal aminoacyl-tRNA synthetases that acylate orthogonal tRNAs with non-canonical monomers, enabling in vivo synthesis of proteins that include these monomers and expanding the repertoire of the genetic code.

The use of mega-electronvolt ultrafast electron diffraction combined with resonance-enhanced multiphoton ionization yields data that can reveal the formation and subsequent structural relaxation of a molecular ion on an ultrafast timescale.

Integrated data, including 100 human genomes from the Mesolithic, Neolithic and Early Bronze Age periods show that two major population turnovers occurred over just 1,000 years in Neolithic Denmark, resulting in dramatic changes in the genes, diet and physical appearance of the local people, as well as the landscape in which they lived.
