The undulating tripod gait as a model of the locomotion of walking fish
Abstract A large subset of fishes capable of terrestrial walking exhibit strikingly similar gaits despite spanning across the phylogenetic space and having substantial differences in morphology. This recurrent pattern suggests the existence of shared mechanical principles underlying locomotor convergence.
Paleoinspired robotics as an experimental approach to the history of life
Abstract Paleontologists must confront the challenge of studying the forms and functions of extinct species for which data from preserved fossils are extremely limited, yielding only a fragmented picture of life in deep time. In response to this hurdle, we describe the nascent field of paleoinspired robotics, an innovative method that builds upon established techniques in bioinspired robotics, enabling the exploration of the biology of ancient organisms and their evolutionary trajectories.
Robotic manipulation of cardiomyocytes to identify gap junction modifiers for arrhythmogenic cardiomyopathy
Editor’s summary The cardiac disease arrhythmogenic cardiomyopathy is associated with deficiencies in cell-to-cell adhesion and can result in sudden fatal arrhythmias. Researchers have attempted to study the gap junctions in cardiomyocytes but have largely relied on manual experimental techniques. Dou et al. have developed a robotic cell manipulation system capable of microinjecting cardiomyocytes, with the ability to offset the spontaneous beating of the cells.

Transforming science labs into automated factories of discovery
Abstract Laboratories in chemistry, biochemistry, and materials science are at the leading edge of technology, discovering molecules and materials to unlock capabilities in energy, catalysis, biotechnology, sustainability, electronics, and more. Yet, most modern laboratories resemble factories from generations past, with a large reliance on humans manually performing synthesis and characterization tasks.
High-resolution outdoor videography of insects using Fast Lock-On tracking
Editor’s summary Studying insects in their natural environments can provide important insight into their behavior. However, videography of flying insects, especially outdoors, is difficult because of their small size and fast motion. After tagging an insect with a distinct marker, Vo-Doan et al. developed a system called Fast Lock-On (FLO) tracking that uses a feedback system to tilt the camera’s mirror position and keep the insect in focus.
Robotic fish reveal steps taken by evolution
Sometime around 375 million years ago, fish made the bold move out of the water and onto land. And although we have a rough idea as to the morphology of the first few species to make this leap, including the famous fish Tiktaalik, the precise structures of their feet-like fins have been lost to time. Fossils, for all they have revealed about our past, tend not to preserve soft tissues, like muscles and tendons, which would reveal how our ancestors first walked.
Mechanism of Copper Uptake from Blood Plasma Ceruloplasmin by Mammalian Cells
Copper is a trace element required for a wide variety of enzymatic reactions critical to most living cells and for the functions of an ever-growing number of other proteins, especially in mammals, whose function is less understood [1–15].
