Synapsis

A study reveals how hippocampal synapses adjust their proteins to specialize their function

A research team has mapped individual synaptic types in the hippocampus, a brain structure critical for learning and memory. The study provides unprecedented resolution of which proteins are present in each type of synapse and their quantities, revealing patterns that help explain how connections perform different functions.

Chromosomes dance and pair up on the nuclear membrane

Researchers at UC Berkeley discover that the cytoskeleton plays a critical role in pairing and recombining chromosomes during meiosis. By forming bridges between chromosomes and patches on the nuclear membrane, the cytoskeleton helps ensure homologous chromosome pairing, a crucial step in sex cells' development.
