Jamming Distance Dictates Colloidal Shear Thickening
PHYSICAL REVIEW LETTERS, 127(15).
TL;DR:
The results suggest that the force per contact is different for particles with different morphologies, and the available free volume for colloids of different roughness is related to the deficiency from the maximum number of nearest neighbors at jamming under shear.

Celebrating Soft Matter's 10th Anniversary: Sequential phase transitions in thermoresponsive nanoemulsions
Soft Matter, 11(43), 8426–8431.
TL;DR:
The coexistence of stress-bearing percolation with arrested phase separation in a colloidal system of thermoresponsive nanoemulsions spanning a broad range of volume fractions and temperatures is reported and it is suggested that the formation of metastable gelled states not only depends on the attraction strength and volume fraction of the system, but is also sensitive to the rate at which the attractionstrength is increased.

Role of isostaticity and load-bearing microstructure in the elasticity of yielded colloidal gels
Proceedings of the National Academy of Sciences, 109(40), 16029–16034.
author keywords: colloids; confocal microscopy; suspensions; shear flow
MeSH headings : Elasticity; Gels / chemistry; Microscopy, Confocal; Molecular Dynamics Simulation; Polymethyl Methacrylate / chemistry; Rheology; Structure-Activity Relationship
TL;DR:
These studies show that bond breakage occurs mainly due to the erosion of rigid clusters that persist far beyond the yield strain, and find a power-law scaling of the elastic modulus with the stress-bearing volume fraction that is valid over a range of volume fractions and gelation conditions.

author keywords: Allee effects; evolution of periodicity; Magicicada; rock-paper-scissors competition; spatial dynamics
TL;DR:
Although not enough information is known about periodical cicadas to draw firm conclusions, the theoretical arguments favor a combination of predator satiation and nymph competition as being key to the evolution of strictly fixed periods and occurrence of only one brood at most geographical locations.
