The external ear canal of cetaceans, vestigial or not? [PDF]
, 2014 Cetaceans descend from land mammals. Consequently, their hearing apparatus basically consists of the same anatomical components. Whales, as land mammals, feature an outer, middle and inner ear.

4D Bioprinted Self‐Folding Scaffolds Enhance Cartilage Formation in the Engineering of Trachea
Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.A bilayer self‐folding scaffold, triggerable by humidity, is fabricated via 4D bioprinting for trachea engineering. An analytical model is derived to predict its radius of curvature, enabling its scalability. Cartilage progenitor cells seeded on the scaffold perceive scaffold final curvature and react to it, by enhancing the upregulation of pro ...
