‘Disulfiram-Containing Polymeric Nanocapsules With Anticancer Activity for Cancer Treatment’
“Disulfiram, a medication traditionally used to treat alcohol addiction, has gained attention as a potential cancer treatment in recent years. Disulfiram works by inhibiting the enzyme aldehyde dehydrogenase, involved in the breakdown of acetaldehyde, a by-product of alcohol metabolism. This results in the build up of acetaldehyde in the body leading to unpleasant side effects such as nausea and vomiting when alcohol is consumed while taking the drug. With cancer treatment, disulfiram has been found to have several mechanisms of action.”Find the paper and full list of authors in the International Journal of Pharmaceutics.

“Many of the organs in our body are built of tubes. … Critical components of these tubular systems are contractile valves and sphincters. … However, tiny valves composed of a just few cells can somehow also perform these functions. In the reproductive system of the nematode C. elegans there is a donut-shaped valve that opens and closes hundreds of times to allow eggs to pass from where they are fertilized to the uterus. The team … will characterize the inner structure of the valve cell with light and electron microscopy and use genetic perturbations to discover the molecular mechanisms that…

‘Nonlinear Optical Responses in Multiorbital Topological Superconductors’
“We theoretically study first- and second-order optical responses in a transition-metal dichalcogenide monolayer with distinct trivial, nodal, and time-reversal invariant topological superconducting (TRITOPS) phases. We show that the second-order dc response, also known as the photogalvanic response, contains signatures for differentiating these phases while the first-order optical response does not. We find that the high-frequency photogalvanic response is insensitive to the phase of the system, while the low-frequency response exhibits features distinguishing the three phases.” Find the paper and full list of authors in Physical Review B.

‘A Computational Account of Transsaccadic Attentional Allocation Based on Visual Gain Fields’
“Saccadic eye movements are the primary means by which people gather information about the environment. An average fixation duration is a fraction of a second in natural viewing conditions. … How the brain maintains perceptual stability across these interruptions remains a mystery. Here, we combined a unique psychophysical protocol with bespoke analytical tools to investigate such active vision with greater spatial and temporal resolution than ever before. We show that the visual system can compute a visual object’s real-world position in the earliest stages of processing, thereby allowing precise object tracking across saccades.” Find the paper and authors list in…

Klein receives Robert Wood Johnson Foundation grant to expand criminal court data
“Criminal municipal courts in the US are standalone courts that operate under the purview of municipalities and cities, as opposed to state judiciaries. They are largely thought to be the ‘lowest’ tier of the criminal legal system. … The general public has little sense of the volume of cases being tried in the system, the amount of money collected by municipalities through fines and fees, and even the number of courts in a given state. In this grant, we take a system-wide approach in collecting, digitizing, and visualizing longitudinal data on every criminal municipal court in every state where they…

Di Pierro receives NSF grant for computational genetics
“Genomes fold into distinct architectures that reflect both the cell’s phase and type, with the spatial organization of genes playing a crucial role in facilitating physical interactions among genetic regulatory elements. These interactions are essential for gene regulation within organisms and tissues.

‘Improved Data Acquisition Settings on … Mass Spectrometers for Proteomic Analysis of Limited Samples’
“Deep proteomic profiling of complex biological and medical samples available at low nanogram and subnanogram levels is still challenging. Thorough optimization of settings, parameters, and conditions in nanoflow liquid chromatography-tandem mass spectrometry (MS)-based proteomic profiling is crucial for generating informative data using amount-limited samples. This study demonstrates that by adjusting selected instrument parameters, … and minimally altering the conditions for resuspending or storing the sample in solvents of different compositions, up to 15-fold more thorough proteomic profiling can be achieved compared to conventionally used settings.” Find the paper and full list of authors in the Journal of Proteome Research.

Monaghan Lab receives NIH funding to research retinoic acid in axolotls
“This study aims to investigate the mechanisms by which retinoic acid modifies chromatin architecture and gene expression to establish the proximodistal (shoulder to digit) axis in the salamander forelimb during regeneration. Utilizing methods in nucleic acid sequencing, in situ visualization, and genome editing, the investigators explore the molecular underpinnings of retinoic acid’s influence on positional identity in regenerating limb cells. The results of this study will deepen our understanding of the fundamental pathways promoting complex tissue regeneration, potentiating novel therapeutic targets in humans, whose regenerative capacity is largely restricted to the digit tip.”

‘Machine Learning for Prediction of Protein Function and Elucidation of Enzyme Function and Control’
“Our machine learning methodology, partial order optimum likelihood (POOL) is used to predict biochemically active amino acids in the three-dimensional structures of proteins. Computed electrostatic and chemical properties of individual amino acids serve as input features. Our most recent applications of POOL are described. From predicted local sites of biochemical activity, the biochemical functions of structural genomics proteins of unknown function are predicted by local structure matching of predicted spatial arrays of active amino acids with those of proteins of known function.” Find the paper and full list of authors in Biophysical Journal.

‘Giant Effective Magnetic Moments of Chiral Phonons From Orbit-Lattice Coupling’
“Circularly polarized lattice vibrations carry angular momentum and lead to magnetic responses in applied magnetic fields or when resonantly driven with ultrashort laser pulses. Recent measurements have found responses that are orders of magnitude larger than those calculated in prior theoretical studies. Here, we present a microscopic model for the effective magnetic moments of chiral phonons in magnetic materials that can reproduce the experimentally measured magnitudes and that allows us to make quantitative predictions for materials with giant magnetic responses using microscopic parameters.” Find the paper and full list of authors in Physical Review B.

‘Intrinsic symmetry-protected topological mixed state from modulated symmetries and hierarchical structure of boundary anomaly’
“We introduce a class of intrinsic symmetry-protected topological mixed state (mSPT) in open quantum systems that feature modulated symmetries, such as dipole and subsystem symmetries. Intriguingly, these mSPT phases cannot be realized as the ground states of a gapped Hamiltonian under thermal equilibrium. The microscopic form of the density matrix characterizing these intrinsic mixed-state SPT ensembles is constructed using solvable coupled-wire models that incorporate quenched disorder or quantum channels. A detailed comparison of the hierarchical structure of boundary anomalies in both pure and mixed states is presented.” Find the paper and full list of authors in Physical Review B.

‘Effective Theory Building and Manifold Learning’
“Manifold learning and effective model building are generally viewed as fundamentally different types of procedure. After all, in one we build a simplified model of the data, in the other, we construct a simplified model of the another model. Nonetheless, I argue that certain kinds of high-dimensional effective model building, and effective field theory construction in quantum field theory, can be viewed as special cases of manifold learning. I argue that this helps to shed light on all of these techniques.”
