Spiking networks compensate the loss of neurons instantaneously, when restoration of excitatory/inhibitory balance becomes equivalent to restoration of functionality.
The overall energy conversion efficiency is calculated for a bacterial vesicle that harvests solar energy for ATP production on the basis of an atomic-detail structural model.
Single-molecule F1FO studies show mutation-dependent pKa changes of both FO half-channels, and proton translocation-dependent 11° ATP synthase-direction sub-steps, which support a Grotthuss proton transfer-dependent two-step FO torque generating mechanism.
Biological shapes and morphological transitions can emerge from combining directed interactions between cells with apical-basal and planar cell polarity.

Sec1/Munc18 (SM) proteins shield SNARE complexes from NSF/Sec18-mediated disassembly through cooperative binding interactions with SNARE complexes and the universal co-chaperone α-SNAP/Sec17.
The structure of the photosystem I (PSI) complex from Synechocystis is determined, and reaction center subunits engineered to resemble a viral PSI are found to promote promiscuous electron acceptor properties.

Quorum-sensing control of Burkholderia thailandensis toxin and immunity pairs serves to police quorum-sensing mutants and may represent a general strategy whereby cooperators can police mutants.
