    Ryanodine Receptors (RyRs) release Ca2+ from the endoplasmic and sarcoplasmic reticulum. Mutations in RyR are linked to malignant hyperthermia (MH), myopathies, and arrhythmias. Here, a collection of cryoEM structures provides insights into the molecular consequences of MHrelated RyR mutation R615C, and how apoCaM opens RyR1.

    Long-term potentiation at hippocampal CA1 synapses can be due to increasing the number and/or single-channel conductance of AMPA receptors. The authors show that PKA and CaMKII are necessary and together sufficient to increase single channel conductance, via insertion of calcium-permeable AMPA receptors.

    The small proton-coupled transporter EmrE confers multidrug resistance in bacteria. The structure of drug-bound EmrE in phospholipid bilayers is now determined using solid-state NMR. The structure provides detailed insights into the molecular mechanism of substrate recognition by this transporter.

    Gdx-Clo is a bacterial transporter from the small multidrug resistance (SMR) family. Here, the authors use solid supported membrane electrophysiology to characterize Gdx-Clo functionally and report crystal structures of Gdx-Clo which confirm the dual topology architecture and offer insight into substrate binding and transport mechanism.

    Current media for neuronal cell and organoid cultures are suboptimal for functional imaging and optogenetics experiments, owing to phototoxicity and unphysiological performance. Here the authors formulate an optimised neuronal medium to support live cell imaging and electrophysiological activity.

    Current methods of neuronal network imaging cannot be used for continuous, long-term functional recordings. Here, the authors present a dual-mode high-density microelectrode array, which can simultaneously record in full-frame and high-signal-to-noise modes for label-free electrophysiological measurements.

    Electrical stimulation of the brain can have variable effects, perhaps because of individual differences in brain structure which produce differences in the electric fields. Here, the authors show that using functional and structural brain imaging along with electric field modeling can predict the effectiveness of stimulation.

    The depolarizing funny current contributing to cardiac pacemaking is upregulated in the myocardium of  failing and infarcted hearts, but whether the current is implied in disease mechanisms is unclear. Here the authors generate HCN4 transgenic mice and show that upregulation of funny current to the levels observed in human heart failure alters calcium homeostasis leading to cardiac remodelling and arrhythmia.

    Transcranial Magnetic Stimulation (TMS) can modulate human brain activity, but the extent of the cortical area activated by TMS is unclear. Here, the authors show that TMS affects monkey single neuron activity in an area less than 2 mm diameter, while TMS-induced activity and task-related activity do not summate.

    Transcranial alternating current stimulation (TACS) of the brain is widely used in neuroscience, but the electric fields produced when multiple stimulation electrodes are used are not well understood. Here, the authors directly record electric fields in primate brains during multi-electrode TACS.

    Magnetoencephalography (MEG) is a non-invasive method of measuring neural activity but the hippocampus and amygdala are difficult to measure with MEG because of their deep localization. Here, the authors show with simultaneous MEG and invasive recordings that hippocampus and amygdala activity can be retrieved from the surface.

    While strain is known to affect cardiac electrophysiology, experimental systems to interrogate the effect of rapid strain cycles on cardiac tissue are lacking. Here the authors introduce a multielectrode array that can induce rapid dynamic strain cycles on cardiomyocyte strands and see effects of strain amplitude but not strain rate on impulse conduction.

    Mutations that modulate the activity of ion channels are essential tools to understand the biophysical determinants that control their gating. Here authors reveal the role played by a single residue in the second transmembrane domain of vertebrate and invertebrate two-pore domain potassium channels.

    Electroencephalography (EEG) allows the measurement of electrical signals associated with brain activity, but it is unclear if EEG can accurately measure subcortical activity. Here, the authors show that source dynamics, reconstructed from scalp EEG, correlate with activity recorded from human thalamus and nucleus accumbens.

    Place cells and grid cells are known to encode spatial information about an animal’s location relative to the surrounding environment. Here, the authors show that place cells predominantly encode environmental sensory inputs, while grid cell activity reflects a greater influence of physical motion.

    Transcranial alternating current stimulation (tACS) uses weak electrical currents, applied to the head, to modulate brain activity. Here, the authors show that contrary to previous assumptions, the effects of tACS on the brain may be mediated by its effect on peripheral nerves in the skin, not direct.

    Memories formed around the same time are linked together by a shared temporal context. Here, the authors show that the ability to selectively retrieve distinct episodic memories formed close together in time is related to how quickly neural representations of temporal context change over time during encoding.

    Direct electrical brain stimulation can induce widespread changes in neural activity, offering a means to modulate network-wide activity and treat disease. Here, the authors show that the low-frequency functional connectivity profile of a stimulation target predicts where induced theta activity occurs.

    Peripheral nerves have a complex physiology and it is therefore difficult to measure axonal activity in vitro. Here the authors make a nerve-on-a-chip platform to align peripheral nerves and permit measurement of conduction amplitude and velocity along several axons in a single experiment.

    A bottleneck for the application of bioelectrochemical systems is the slow rate of extracellular electron transfer. Here the authors use a synthetic biology approach to redirect metabolic flux to NAD+ biosynthesis, which enhances the intracellular electron flux and the extracellular electron transfer rate.

    The BRICHOS domain is a chaperone that can act against amyloid-β peptide fibril formation and non-fibrillar protein aggregation.

    Circadian rhythms usually rely on cyclic variations in gene expression. Red blood cells, however, display circadian rhythms while being devoid of nuclear DNA. Here, Henslee and colleagues show that circadian rhythms in isolated human red blood cells are dependent on rhythmic transport of K+ ions.
