‘Physical Activity-Related Individual Differences in Functional Human Connectome Are Linked to Fluid Intelligence in Older Adults’
“The study examined resting state functional connectivity (rs-FC) associated with moderate-to-vigorous physical activity (MV-PA), sedentary time (ST), TV viewing, computer use and their relationship to cognitive performance in older adults. We used pre-intervention data from 119 participants from the Fit & Active Seniors trial. … Our findings suggest that greater functional integration within networks implementing top-down control and within those supporting visuospatial abilities, paired with segregation between networks critical and those not critical to top-down control, may help promote cognitive reserve in more physically active seniors.” Find the paper and full list of authors at Neurobiology of Aging.

‘Spin–Orbit Exciton–Induced Phonon Chirality in a Quantum Magnet’
“Phonons are known as an important energy carrier and their interaction with electrons is critical for understanding exotic properties in correlated materials. … Chiral phonons arising from circular ionic motions alone would only exhibit a small magnetic moment. In contrast, chiral phonons reported recently in several classes of materials including the pseudogap phase of cuprates and topological semimetals exhibit surprisingly large moments. Here, we report studies of chiral phonons in CoTiO3, a quantum magnet that hosts interesting bosonic excitations such as topological magnons and spin–orbit excitons.” Find the paper and full list of authors at PNAS.

Wales will target ‘SHP-1 through a newfound metabolite-regulated cysteine activation site’
“This new project is focused on chemical manipulation and characterization of SHP-1 based on recent insights, gained in large part from the development of mass spectrometry approaches to map small molecule covalent interactions proteome-wide done in the Chouchani laboratory. My research group will apply hydrogen-deuterium exchange (HDX) mass spectrometry (MS) to investigate conformational changes of SHP-1 upon binding to itaconate and itaconate-mimetics to ascertain if SHP-1 activation leads to conformational rearrangement and then determine where those rearrangements take place within SHP-1. These HDX MS studies will provide solution-based measurements that will complement the X-ray crystallography studies of the same system.”

‘Effect of Emotion Naming on Emotion Regulation in Younger and Older Adults’
“Prior research has shown that naming one’s emotions before regulation has a detrimental effect on regulation success (Nook et al., 2020). … The aim of the current replication-extension study was to evaluate whether this effect would replicate in an older adult sample. Due to age-related changes in emotion regulation knowledge and behaviors, we hypothesized that age would moderate this effect. … However, contrary to our hypothesis, this effect was larger in older adults (d=.82) than younger adults (d=.41). These findings suggest that affect crystallization may be stronger or faster in older adulthood.” Find the paper and list of authors at Innovation…

‘Associations Between Cognitive Resources and Emotion Regulation Tactics in an Adult Lifespan Sample’
“The current study investigated how trait-level cognitive capacity relates to emotion regulation tactic preferences in everyday life in adulthood and old age. 51 younger adults (ages 18-39), 53 middle-aged adults (ages 40-59), and 55 older adults (ages 60+) completed measures of working memory and verbal fluency, as well as 21 days of experience sampling. On each survey, participants indicated if they had regulated since the last survey and if so, what emotion regulation strategies they used and how they implemented that strategy through specific emotion regulation tactics.” Find the paper and full list of authors at Innovation in Aging.

‘Modeling the Role of Immune Cell Conversion in the Tumor-Immune Microenvironment’
“Tumors develop in a complex physical, biochemical, and cellular milieu, referred to as the tumor microenvironment. Of special interest is the set of immune cells that reciprocally interact with the tumor, the tumor-immune microenvironment (TIME). … While tumor cells are known to induce immune cells to switch from anti-tumor to pro-tumor phenotypes, this type of ecological interaction has been largely overlooked. To address this gap in cancer modeling, we develop a minimal, ecological model of the TIME with immune cell conversion, to highlight this important interaction and explore its consequences.” Find the paper and authors list at Bulletin of Mathematical…

‘Switching the Spin Cycloid in BiFeO3 With an Electric Field’
“Bismuth ferrite (BiFeO3) is a multiferroic material that exhibits both ferroelectricity and canted antiferromagnetism at room temperature, making it a unique candidate in the development of electric-field controllable magnetic devices. The magnetic moments in BiFeO3 are arranged into a spin cycloid, resulting in unique magnetic properties which are tied to the ferroelectric order. Previous understanding of this coupling has relied on average, mesoscale measurements. Using nitrogen vacancy-based diamond magnetometry, we observe the magnetic spin cycloid structure of BiFeO3 in real space.” Find the paper and full list of authors at Nature Communications.

Weng receives USDA funding to explore cyclic peptide biosynthesis
“Plants offer an enormous chemodiversity that is essential for discovering new medicines, with 25% of all FDA-approved drugs coming from plants. However, the production of plant-derived natural products faces significant challenges. Our research [explores] the biosynthesis and bioengineering of lyciumins and moroidins, two classes of branched cyclic peptides with potential pharmaceutical applications. Lyciumins, inhibitors of the human angiotensin-converting enzyme, come from the Goji berry, while moroidins, derived from the Australian stinging tree, exhibit anti-mitotic activities suitable for cancer therapy. … We propose to advance our understanding of RiPP diversity and biosynthesis, supporting new strategies for their engineering and application in…

‘A Gradient of Unisons: The Emergent Superunit in Collective Action’
“As design practice shifts from designing material goods to shaping and facilitating social situations, there is a compelling need to develop a richer understanding of specific social relations as facilitated by design. This article explores bodied unisons—enkinaesthetic entrainments of self + other. We present these unison acts as identifiable patterns of behavior that are observable when people coordinate, patterns that foster a move from individual to superunit.” Find the paper and full list of authors at Design Issues.

‘Quasi-Fermi Liquid Behavior in a One-Dimensional System of Interacting Spinless Fermions’
“We present numerical evidence for a paradigm in one-dimensional interacting fermion systems, whose phenomenology has traits of both Luttinger liquids and Fermi liquids. This state, dubbed a quasi-Fermi liquid, possesses a discontinuity in its fermion occupation number at the Fermi momentum. The excitation spectrum presents particlelike quasiparticles and absence of holelike quasiparticles, giving rise instead to edge singularities.” Find the paper and full list of authors at Physical Review B.

‘Rigor With Machine Learning From Field Theory to the Poincaré Conjecture’
“Despite their successes, machine learning techniques are often stochastic, error-prone and blackbox. How could they then be used in fields such as theoretical physics and pure mathematics for which error-free results and deep understanding are a must? In this Perspective, we discuss techniques for obtaining zero-error results with machine learning, with a focus on theoretical physics and pure mathematics. Non-rigorous methods can enable rigorous results via conjecture generation or verification by reinforcement learning. We survey applications of these techniques-for-rigor ranging from string theory to the smooth 4D Poincaré conjecture in low-dimensional topology.” Find the authors list in Nature Reviews: Physics.
