Non-uniformities in the layer of passivator molecules, which are used to fix defects and protect the surface of perovskite material in solar cells, can limit the durability of the resulting modules. Large modules treated instead with chemically stable lead carboxylate passivators were efficient, reliable and had a higher yield than did commercial silicon modules.

The plant Rhynchospora tenuis has no exchange of DNA between parental chromosomes during the production of male and female sex cells. Even so, it still transmits chromosomes and retains sexual reproduction. This unusual system restores parental genetic variants, leading to clonal-like inheritance across generations despite sex-cell production and fertilization.

Single-nucleus RNA sequencing captures molecular changes in the prefrontal cortex across the lifespan and in health and disease.

Variants in genes involved in the production of extracellular matrix molecules could have enabled the skeletal adaptations that distinguish humans from other great apes.
