Modulation of the energy barrier for membrane fusion is a common mechanism by which sensors in the synapse produce supralinear calcium dependence of vesicle release and short-term synaptic potentiation.
Structure, dynamics, and mutation of a gamete fusion protein and comparisons to viral homologues suggest that after trimerization the domain bearing the membrane-inserting fusion loops can pivot with respect to the trimer 3-fold axis.
Well-controlled psychological experiments show that there is little overlap in how humans and convolutional networks classify adversarial images, highlighting the problem of using CNNs as models of human vision.
Fibrolamellar carcinoma results from a genetic lesion that produces the DNAJ-PKAc fusion kinase, which is recruited into macromolecular complexes and is sensitive to combinations of signal transduction inhibitor drugs.
New experiments and theory reveal how the ability to see image details depends upon photoreceptor function and eye movements, and how fruit flies (Drosophila) see spatial details beyond the optical limit of their compound eyes.
