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…
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…
ESA microgravity experiments revealed gravity’s effects on soft matter flow
What the study found The review finds that European Space Agency (ESA) microgravity experiments have produced high-precision measurements across several soft-matter systems. These studies showed, among other results, interfacial viscoelasticity, plastic rearrangements in colloidal glasses, roaming bubbles in foams, progressive arrest of droplet motion in emulsions, margination effects in blood cell analogues, and the impact…
