Rheology of bacteria and biofilms in space conditions
What the study found The article discusses bacterial suspensions and biofilms as systems whose rheological properties, or flow and deformation behavior, are affected by gravity and possibly microgravity. It also describes biofilms as viscoelastic active matter with dynamic properties that can adapt their structure in response to external stresses. Why the authors say this matters…
Bioinspired principles guide underwater soft robot design
—
in EngineeringWhat the study found The study identifies four biological principles that guide the design of underwater soft robots: locomotion, compliant morphologies and materials, distributed sensing, and adaptive control. It also describes a bidirectional loop from biology to robotics and back, in which robots can be used as physical models to investigate biological mechanisms. Why the…
Toggled magnetic fields drive continual restructuring of ribbonlike colloids
—
in EngineeringWhat the study found Ribbonlike aggregates formed in paramagnetic colloidal suspensions showed ongoing dynamic instabilities when an external field was toggled on and off. These instabilities included spontaneous emission of small aggregates, merging, and splitting, and they increased total motion in the suspension. Why the authors say this matters The authors suggest that the dynamic…
