New 3D imaging and visualization technique provides detailed views of muscle architecture

https://www.sciencedaily.com/releases/2019/04/190430132301.htm?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+sciencedaily%2Fplants_animals%2Fbirds+%28Birds+News+--+ScienceDaily%29


In a new study, scientists in pathology and anatomical sciences in the University of Missouri's School of Medicine have revealed a three-dimensional view of the skeletal muscles responsible for flight in a European starling. The study will form the basis of future research on the bird's wishbone, which is supported by these particular muscles and is hypothesized to bend during flight.

Media Release: Nature's Dangerous Decline 'Unprecedented'; Species Extinction Rates 'Accelerating'

In this Dec. 4, 2018, file photo, birds fly past a smoking chimney in Ludwigshafen, Germany. Development that's led to loss of habitat, climate change, overfishing, pollution and invasive species is causing a biodiversity crisis, scientists say in a new United Nations science report released Monday, May 6, 2019.

Why Is This Ostrich Wearing an Extra Set of Wings? (video)

Paper: Identification of avian flapping motion from non-volant winged dinosaurs based on modal effective mass analysis

https://journals.plos.org/ploscompbiol/article?id=10.1371/journal.pcbi.1006846


Fig 3. Biophysical vibration of the wings.

(A) Wearable devices to detect the performance of wings. The back bracket was manufactured through 3D printer with ABS plastics. The angular accelerometer sensor, force sensor and SD card were all mounted on the bracket (S3B Fig). The accelerometer sensor on the back and the wings were used to measure the rolling angle of body and wings respectively during locomotion on the ground. A force sensor is embedded between the arm and the body to measure the lift generated by the flapping wings (S3A Fig). (B) Simplified wing mechanism. Every wing has a flexible structure that is jointed with the body via elastic rubber belts, which are used to simulate the function of muscles. (C) Reconstruction of wings of different sizes. The first wing represents the forearm with filament feathers. From the second one to the fourth one, the length of feathers increases gradually. The second one represents the short feather, the third one represent middle feather while the fourth one with the longest feathers represents the largest wing (the realistic wing is the third one in accordance to the fossil).
