The numerous reports in support of action-value representation in the striatum are based on statistical analyses that are subject to two critical confounds and, thus, this long-held belief of striatal action-value representation should be retested using different experiments and analyses.

Drug-resistance declines in the laboratory in an antibiotic stress-free environment, indicating that restricting antimicrobial usage in the clinics could be a useful policy.

Experiments in genetically modified zebrafish that are unable to produce norepinephrine show that this neurotransmitter promotes wakefulness by mediating the effects of the neuropeptide hypocretin.

During human running, the soleus muscle was found to operate as work generator under optimal conditions for work production (high force-length potential and enthalpy efficiency) while the vastus lateralis promoted tendon energy storage and economical force generation (high force-length-velocity potential).

Naturally occurring activity in the developing brain regulates mitochondrial motility such that mitochondria stop at active synapses, which is probably a fundamental process in brain wiring.

Theoretical explanation and a novel mechanism are given for the observation that viscosity of embryonic non-confluent tissue shows glass-like behavior till a critical cell density and saturates at higher densities.

The anterior cingulate cortex intermixes a precise spatial map with a cognitive map of the task, and spontaneously recalls multimodal information about unrealized choice outcomes during pauses in behavior after reinforcements.

The three main types of inhibitory neurons in mouse primary visual cortex respond differently to locomotion in darkness and during visual stimulation, revealing context-dependent responses to changes in behavioral state.

Compared with casirivimab/imdevimab and bamlanivimab/etesevimab, early treatment with sotrovimab seems to reduce the time to sustained recovery among adult outpatients with mild-to-moderate SARS-CoV-2 infection due to Omicron BA.1 and BA.1.1.

Competition between neurons on the left and right sides of the brain drives the decision to turn left versus right in zebrafish, and potentially all vertebrates.
