“White and Clear” (WaC): A tunable hydrophilic tissue clearing strategy for multi‐species 3D imaging

open access: yesVIEW, EarlyView.
Optical tissue clearing methods help scientists make tissues transparent to image structures deep inside organs in 3D, but many existing techniques are limited in performance and difficulty. In this study, we developed an optimized clearing method called WaC (White and Clear), which improves upon existing techniques by combining efficient tissue ...

Soil drought imposes moderate, temporary costs on a strictly fossorial amphisbaenian reptile. However, these animals seem to cope with, at least, moderately short droughts thanks to their peculiar adaptations to living in an underground environment. ABSTRACT The physiological traits of animals can be strongly influenced by climatic fluctuations, and ...
