At the interface between Asia and Europe, the Caucasus region was a melting pot during the Bronze Age and the origin of the earliest steppe pastoralist societies. Ancient-DNA analyses reveal how Neolithic ways of life spread through diverse populations and how mountain–steppe interactions transformed the genetic and cultural landscapes of Eurasia.

By patterning an ultrathin layered structure with tiny wells, physicists have created and imaged peculiar states known as quantum scars — revealing behaviour that could be used to boost the performance of electronic devices.

Neuronal population activity in the anterior temporal lobe of the human brain organizes into bursts of spiking in response to visual images. The specific sequence of neuronal firing in these bursts encodes category- and exemplar-related information about these images, complementing the well-established role of firing rates in neural coding.

A high power conversion efficiency of 26.4% has been achieved for tandem solar cells that consist of a wide-bandgap perovskite cell and an organic cell. This feat was made possible through an investigation of the mechanisms by which two isomeric structures of a diammonium molecule passivate (repair) defects on the surface of the perovskite.
