Topology, symmetry and quantum band theory
In this review, “Topology and Symmetry in Quantum Materials,” the authors present an overview of “band theory,” and “presents a cross section through the recent work on understanding the role of geometry and topology in generating topological states and their responses to external stimuli, and as a basis for connecting theory and experiment within the band theory framework.” Find the paper and the full list of authors at Advanced Materials.

Modeling floodplain lakes after extreme flooding
This study of floodplain lakes—which accumulate “sediments, organic matter, and pollutants”—adds to our understanding of their evolution, especially after flooding events. While pre-existing models of floodplain lake evolution exist, they are “not well suited to guide the interpretation of individual flood events in sedimentary records.” This paper “combine[s] sediment samples collected in and around a floodplain lake with hydraulic modelling simulations to examine inundation, flow velocity, and sedimentation patterns,” especially helpful after “extreme” flood events. Read “A Hydraulic Modelling Approach to Study Flood Sediment Deposition in Floodplain Lakes” and find the full list of authors in Earth Surface Processes and…

‘Quench Dynamics in the One-Dimensional Mass-Imbalanced Ionic Hubbard Model’
“Using the time-dependent Lanczos method, we study the non-equilibrium dynamics of the one-dimensional ionic-mass imbalanced Hubbard chain driven by a quantum quench of the on-site Coulomb interaction, where the system is prepared in the ground state of the Hamiltonian with a different Hubbard interaction. A full exact diagonalization is adopted to study the zero temperature phase diagram in equilibrium, which is shown to be in good agreement with previous studies using density matrix renormalization group (DMRG).” See the full list of authors and read their research in ArXiv.

Music is good for the brain, and not just among professionals
This study, “Musical Experience Relates to Insula-Based Functional Connectivity in Older Adults,” a collaboration between the department of physical therapy, the department of music and the department of psychology at Northeastern University, in addition to the University of Illinois at Urbana-Champaign, looked at “general musical experiences” across a subject’s lifespan, particularly in older adults. Their findings show that “older adults with more musical experience showed greater functional connectivity” between insulae and various regions of the brain. “Sensorimotor function and cognitive control” especially seem to benefit.

Advances made against trypanosomiasis, ‘sleeping sickness’
Researchers compared the perturbations of proteins in response to two treatments to human African trypanosomiasis, or sleeping sickness. The workflow identified the differences between NEU-4438 (“a lead for the development of drugs against Trypanosoma brucei,” the parasite responsible for sleeping sickness) and acoziborole, a more common treatment. See the full list of authors and read their research paper at iScience: “Hypothesis-generating proteome perturbation to identify NEU-4438 and acoziborole modes of action in the African Trypanosome.”

‘Scaling Laws for Two-Dimensional Dendritic Crystal Growth in a Narrow Channel’
“We investigate analytically and computationally the dynamics of 2D needle crystal growth from the melt in a narrow channel. Our analytical theory predicts that, in the low supersaturation limit, the growth velocity V decreases in time t as a power law V∼t−2/3, which we validate by phase-field and dendritic-needle-network simulations.” See the full list of authors and read this pre-print at ArXiv.

Functional insights into protein signaling
This review in the journal Life provides “Functional Insights into Protein Kinase A (PKA) Signaling from C. elegans.” PhD. students Fereshteh Sadeghian and Perla Castaneda, along with postdoctoral researcher Mustafi Amin and professor of biology Erin Cram, write that Caenorhabditis elegans, an unsegmented nematode, “provides a powerful genetic platform for understanding how [PKA] can regulate an astounding variety of physiological responses.”

Better diagnoses for visual vergence disorders
Common vergence disorders, characterized by instability between a subject’s eyes as they try to focus on an object (convergence and divergence), can be diagnosed by examining the horizontal fusional reserves of the eye. This study looks at “Infrared eyetracking technology [which] shows promise for obtaining automated and objective measurements of fusional reserves.” This paper is the result of an international collaboration with the University of Auckland, New Zealand. See the full list of authors and read their research, “Objective estimation of fusional reserves using infrared eye tracking: the digital fusion-range test,” in Clinical and Experimental Optometry.

Coastal upwelling helps delicate species survive
This article is an important addition to our understanding of species abundance and distribution—a subject becoming ever more important with ongoing climate change. For this study, researchers used “wavelet analysis” to examine sixteen intertidal zones along the the coast of Europe. Results show that “upwelling”—a process that brings deep, cold water to the surface—produces refuges for thermally delicate species by mitigating rising temperatures. See the full list of authors and read “Coastal upwelling generates cryptic temperature refugia” in Nature.

‘Effect of Dissolved Humic Acids and Coated Humic Acids on Tetracycline Adsorption by K₂CO₃-Activated Magnetic Biochar’
“Humic acids (HAs) widely exist in water environment, and has an important impact on the adsorption of pollutants. Herein, HAs (both dissolved and coated) was employed to assess the effect on the removal of the organic contaminant tetracycline (TC) by K2CO3 modified magnetic biochar (KMBC). Results showed that low concentration of dissolved HAs promoted TC removal, likely due to a bridging effect, while higher concentration of dissolved HAs inhibited TC adsorption because of the competition of adsorption sites on KMBC.” Find the paper and the full list of authors in Scientific Reports.
