Local presynaptic protein synthesis occurring at established nerve terminals in the mammalian brain provides a mechanism for rapidly controlling or restoring presynaptic proteins that affect neurotransmitter release and presynaptic efficiency.

In mammals, the vesicular glutamate transporter 1 acquired a proline-rich sequence that negatively regulates the spontaneous release of glutamate by reducing the exchange of synaptic vesicles along the axon.

Test-and-release quarantine strategies for traced contacts of confirmed SARS-CoV-2 cases and returning travellers can reduce average quarantine durations while remaining as effective as 10 days of quarantine without testing.
Targeting a genetically-encoded glutamate sensor to postsynaptic sites demonstrates the feasibility of simultaneous optical quantal analysis of many inputs to a neuron in wide-field fluorescence microscopy.
