Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint

open access: yesThe Anatomical Record, Volume 309, Issue 5, Page 1299-1312, May 2026.
Abstract Prokinesis—in which a craniofacial joint allows the rostrum to move relative to the braincase—is thought to confer diverse advantages in birds, mostly for feeding. A craniofacial joint would, however, be a weak link if cranial stability is important. Paradoxically, we have identified a craniofacial joint in helmeted hornbills (Rhinoplax vigil),

The Effect of Cluster Sets and Accentuated Eccentric Loading on Vertical Jump Performance and Strategy During Lower‐Body Complex Training

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 5, May 2026.
ABSTRACT This study assessed general and more detailed post‐activation performance enhancement responses to cluster sets (CS) + accentuated eccentric loading (AEL) versus a traditional method (TRD) in vertical jump performance and strategy. Six men and six women completed lower‐body complex training: countermovement jump was performed at baseline and 1‐

Is the Deep Martian Mantle Heterogeneous? A Reappraisal of Seismological Evidences

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract It has been proposed that the deep Martian mantle contains distributed heterogeneities preserved since the accretion of the planet. This result relies on a multiple‐scattering interpretation of frequency‐dependent arrival times of P $P$‐waves detected in the spectrograms of teleseismic Martian events.

Wide‐Range Adaptive Metal Oxide for Hydrogen Sulfide Detection From Earth to Space‐Like Environments

open access: yesAdvanced Science, Volume 13, Issue 19, 2 April 2026.
This work presents a gas sensing platform based on Cu‐doped SnO2 microspheres that operates reliably from ambient to space‐like conditions. The sensor maintains performance across vacuum and cryogenic environments, bypassing traditional oxygen‐mediated mechanisms, utilizing direct chemisorption and interfacial charge transfer.

Application of holography to flow visualization [PDF]

open access: yes
Laser holographic interferometry is being applied to many different types of aerodynamics problems. These include two and three dimensional flows in wind tunnels, ballistic ranges, rotor test chambers and turbine facilities. Density over a large field is

Muscle Weakness and the Irisin–BDNF and Oxidative Stress Axis in the 60‐Day Pseudorandomised Controlled AGBRESA Bed Rest Study

open access: yesJournal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 2, April 2026.
ABSTRACT Background Muscle atrophy and weakness are among the most detrimental consequences of disuse, microgravity, hospitalisation and ageing. Oxidative modifications of myofibrillar proteins generated by oxidative stress may contribute to the reduced force‐ and power‐generating capacity of skeletal muscles. As part of the 60‐day AGBRESA bed rest (BR)

Validation of Intravoxel Incoherent Motion MRI Using Perfused Explanted Human Livers

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 4, Page 2291-2304, April 2026.
ABSTRACT Purpose Evaluate the feasibility of using perfused explanted human livers for validating intravoxel incoherent motion (IVIM). Methods Eight (n = 8) explanted livers from deceased donors were obtained. The portal vein and hepatic artery of each explanted liver were connected to a perfusion system.

The Effect of Voxel Volume and Voxel Shape on Cardiac Diffusion Tensor Imaging Metrics

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 4, Page 2063-2077, April 2026.
ABSTRACT Purpose Cardiac diffusion tensor imaging (cDTI) is signal‐to‐noise ratio (SNR)‐limited due to diffusion signal attenuation, long echo times from gradient moment nulling, and moderate myocardial T 2$$ {}_2 $$. Increasing voxel volume improves SNR but reduces spatial sensitivity and introduces physiological bias.
