Holding a wing horizontal: Roles for muscles of the pectoral girdle other than the main two flight muscles

Journal of Anatomy, Volume 248, Issue 5, Page 830-842, May 2026.
This report explores which muscles of the pectoral girdle are employed to allow birds to hold their wings horizontally with a level aerofoil surface during a glide. Abstract Whilst many birds glide briefly with wings held horizontally, some species maintain this posture for extended periods during soaring.

Ossification of the cranium of Inpaichthys kerri (Characiformes: Acestrorhamphidae) with discussion of paedomorphic traits in the genus

Journal of Anatomy, Volume 248, Issue 5, Page 806-829, May 2026.
In this study, we present a detailed description of the cranial development of Inpaichthys kerri (Characiformes: Acestrorhamphidae), highlighting important topics such as pedomorphic characters and their relationship with ontogeny and phylogeny, as well as ossification sequences unique to the species. Abstract The study of development provides valuable

Contactless Acoustic Trapping of Hoverflies for Behavioral Studies

Annals of the New York Academy of Sciences, Volume 1559, Issue 1, May 2026.
We present a contactless tethering device based on acoustic levitation. Opposing ultrasonic transducers generate standing waves, creating stable pressure nodes that enable the sustained levitation of hoverflies (Episyrphus balteatus). We show that acoustic levitation does not appear to affect hoverfly behavior.
