Tendon‐Driven Compliant Wheel‐Less Snake Robot for Undulatory Locomotion Using Conformable Ground Contacts

Advanced Intelligent Systems, EarlyView.
This study presents a tendon‐driven compliant snake robot that uses globally applied vertical bending and axial twisting along its body to enable various gaits. Body deflection from compliance and weight passively generates the ground contact patterns required for locomotion.

Redox‐Responsive Mitochondrial Delivery from Functionalized Vascular Stent Surfaces

Advanced NanoBiomed Research, EarlyView.
A redox‐responsive stent surface is engineered to deliver functional mitochondria in response to oxidative stress. Upon exposure to reactive oxygen species, grafted mitochondria are released, internalized by vascular cells, and restore mitochondrial function under stress.

Under the Shade of a Coolabah Tree: A Second Cache of Tulas From the Boulia District, Western Queensland

Archaeology in Oceania, EarlyView.
ABSTRACT This paper reports on the excavation of a cache of stone artefacts, buried on the bank of a waterhole or ‘billabong’ in central western Queensland. This is an extremely rare find, and yet it is the second such site to be reported within less than a 10 km radius.
