Spring and Power in Hovering Ornithopters

open access: yesAdvanced Intelligent Systems, EarlyView.
Only small ornithopters can hover, longest at the hummingbird size. This article reviews the drive and power of these hovering machines, focusing on elastic energy and thrust boosters. Unlike two‐winged designs, X‐winged and multiple‐V‐winged ornithopters benefit from lower disk loading and slower, smaller wingbeats, and the clap‐and‐fling effect ...

Bioprinting‐Assisted Tissue Assembly to Investigate Endothelial Cell Contributions in Cardiac Fibrosis and Focal Fibrosis Modeling

open access: yesAdvanced NanoBiomed Research, EarlyView.
GA: Bioprinting‐assisted tissue assembly, a method for generating versatile and complex tissue constructs, is employed to investigate the contribution of endothelial cells (ECs) in cardiac fibrosis. ECs modulate fibrotic responses not only by preventing significant tissue stiffening and contractile impairment but also by exhibiting endothelial‐to ...

The Dispersal of Snails by Birds [PDF]

open access: yesNature, 1921
I WAS present at a meeting of the Malacological Society last May when Dr. Boycott read a very interesting paper, in which he showed how the small snail Balea perversa occurred on trees, walls, and rocks, but not on the ground. The question arose how it got from tree to tree; and in the resulting discussion the fact was brought out that it had ...
