Some species of bats hunt for insects that are resting on surfaces by detecting interruptions in the echoes from that surface, suggesting that resting on rough surfaces may help insects to evade detection by echolocation.

A first-principles acoustics model reveals how the acoustic spectrum generated by flapping wings originates from oscillating aerodynamic forces, and is validated by in vivo aerodynamic force measurements and acoustic holography.

Psychophysics experiments and EEG recordings reveal that people's performance in detecting unexpected changes in complex auditory scenes can be modeled as a process of sensory evidence accumulation.

The use of high-density optical brain imaging in listeners with cochlear implants shows increased activity in frontal cortex during speech perception compared to those with normal hearing.
Everyday soundscapes dynamically engage attention towards target sounds or salient ambient events, with both attentional forms engaging the same fronto-parietal network but in a push-pull competition for limited neural resources.
The combination of optical diffraction tomography and Brillouin microscopy in a single setup enables to quantitatively map the viscoelastic properties of cellular compartments such as aggregates and stress granules in vivo.

The silent production of words in one's mind generates an efference copy that is similar in nature to the efference copy associated with overt vocalization.
The categorical organization of the ventral occipito-temporal cortex, typically thought to be a visual region, is actually partially independent of visual input and even visual experience.
In the processing of spoken narratives, bottom-up acoustic cues and top-down linguistic knowledge separately contribute to neural construction of linguistic units.

Multi-area recordings reveal how communication between two songbird brain areas conveys a top-down bias that adaptively modifies ongoing singing to support context-specific vocal learning.
