Brain-wide association studies, which aim to link features of the brain to a person’s characteristics, have a replicability problem. Besides increasing sample size, what else can be done to make these studies more reproducible?

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.
