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.
The aged human auditory cortex shows preserved tonotopy, but temporal modulations are represented with a markedly broader tuning, highlighting decreased temporal selectivity as a hallmark of the aging auditory cortex.
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.
Combined cell labelling with a bi-cistronic reporter-gene vector and gold nanorods enables short- and long-term cell tracking in vivo via multimodal imaging (multispectral optoacoustic tomography, bioluminescence, fluorescence) with high spatial resolution.
