Neurons in the midbrain superior colliculus of free-flying echolocating bats represent 3D sensory space, and the depth tuning of single neurons is modulated by an animal's active sonar inspection of physical objects in its environment.

Fish schools showed an U-shaped metabolism-speed curve and reduced the energy use per tail beat up to 56% at high swimming speeds compared to solitary fish.

Doves improve their wingbeat efficacy without elevating maximum pectoralis power by angling their wings mid-downstroke to efficiently generate aerodynamic force while simultaneously tensioning the supracoracoideus tendon to assist the upstroke.

Individuals with a history of adverse childhood experiences show blunted response to threat and reward irrespective of sample and paradigm characteristics and despite heterogeneity in adversity operationalization and assessment.

The neuronal glutamate transporter EAAC1 limits excitation and lateral inhibition between D1-MSNs, which are important for the execution of slow-switching flexible behaviors.

The behavioral ability of mice and treeshrews to detect visual figures is highly texture dependent, unlike that of primates including macaques and mouse lemurs, and neural responses to figures in mouse visual cortex are similarly texture dependent.

Self-motivated learning in the absence of external feedback can recruit the same brain network as reward-driven learning.

Opioids cause hyperpolarization and pre-synaptic suppression among a subset of preBötzinger Complex neurons to impair respiratory rhythmogenesis.

The eggshells of palaeognath birds (e.g. ostrich, moa, kiwi, emu) have diverse homology and convergent features, and are useful modern analogues for the evolution of non-avian dinosaur eggshells.

Two of the most commonly mutated growth factor pathways induce a deadly feature of lung adenocarcinoma.
