‘Responses of Littorina spp. Intertidal Snails to Thermal Extremes Indicate Countergradient Variation in Fitness’
“Global change models predict not only a steady increase in temperatures but also an increase in the occurrence of hot and cold extremes. Organisms’ responses to thermal extremes will depend on species-specific traits and the degree of within-species variation (among populations). … The evolution of population-specific responses, however, can be limited by gene flow that homogenises populations. Here, we investigate this relationship with a study of the survival of Littorina littorea, L. obtusata, and L. saxatilis—marine snails with varying dispersal potential—collected on either side of a known biogeographic break.” Find the paper and list of authors in Ecology and Evolution.

‘A Phosphorylation Signal Activates Genome-Wide Transcriptional Control by BfmR’
“The nosocomial pathogen Acinetobacter baumannii is a major threat to human health. The sensor kinase-response regulator system, BfmS-BfmR, is essential to multidrug resistance and virulence in the bacterium and represents a potential antimicrobial target. Important questions remain about how the system controls resistance and pathogenesis. Although BfmR knockout alters expression of >1000 genes, its direct regulon is undefined. Moreover, how phosphorylation controls the regulator is unclear. Here, we address these problems by combining mutagenesis, ChIP-seq, and in vitro phosphorylation to study the functions of phospho-BfmR.” Find the paper and full list of authors in Nucleic Acids Research.

‘A Prospective Real-Time Transfer Learning Approach To Estimate Influenza Hospitalizations With Limited Data’
“Accurate, real-time forecasts of influenza hospitalizations would facilitate prospective resource allocation and public health preparedness. State-of-the-art machine learning methods are a promising approach to produce such forecasts, but they require extensive historical data to be properly trained. Unfortunately, data on influenza hospitalizations, for the 50 states in the United States, are only available since the beginning of 2020. In addition, the data are far from perfect as they were under-reported for several months before health systems began consistently submitting their data. To address these issues, we propose a transfer learning approach.” Find the paper and list of authors in Epidemics.

‘3D Spatial Distribution of Sost mRNA and Sclerostin Protein Expression in Response to In Vivo Tibia Loading in Female Mice’
“Bones adapt to external mechanical loads through a process known as mechanoadaptation. Osteocytes are the bone cells that sense the mechanical environment and initiate a biological response. Investigating the changes in osteocyte molecular expression following mechanical loading has been instrumental in characterizing the regulatory pathways involved in bone adaptation. … In this study, we used WISH-BONE (Whole-mount In Situ Histology of Bone) to investigate the spatial distribution of Sost-mRNA transcripts and its encoded protein, sclerostin, in 3D mouse tibia midshaft following in vivo tibia loading.” Find the paper and full list of authors in Bone.

‘Human Mobility Is Well Described by Closed-Form Gravity-Like Models Learned Automatically From Data’
“Modeling human mobility is critical to address questions in urban planning, sustainability, public health, and economic development. … At one end of the modeling spectrum we have gravity models, which are easy to interpret but provide modestly accurate predictions of flows. At the other end, we have machine learning models, … which predict mobility more accurately than gravity models but do not provide clear insights on human behavior. Here, we show that simple machine-learned, closed-form models of mobility can predict mobility flows as accurately as complex machine learning models, and extrapolate better.” Find the paper and list of authors in…

‘A Hypothesis: Metabolic Contributions to 16p11.2 Deletion Syndrome’
“16p11.2 deletion syndrome is a severe genetic disorder associated with the deletion of 27 genes from a Copy Number Variant region on human chromosome 16. … We present a hypothesis in which changes in the dosage of 16p11.2 metabolic genes contribute to pathology through direct or indirect alterations in pathways that include amino acids or proteins, DNA, RNA, catabolism, lipid, energy (carbohydrate). This hypothesis suggests that research into the specific roles of each metabolic gene will help identify useful therapeutic targets.” Find the paper and full list of authors in BioEssays.

‘Model Supports Asymmetric Regulation Across the Intercellular Junction for Collective Cell Polarization’
“Symmetry breaking, which is ubiquitous in biological cells, functionally enables directed cell movement and organized embryogenesis. Prior to movement, cells break symmetry to form a well-defined cell front and rear in a process called polarization. In developing and regenerating tissues, collective cell movement requires the coordination of the polarity of the migration machineries of neighboring cells. … Here, we investigated how polarity signals are communicated from one cell to its neighbor to ensure coordinated front-to-rear symmetry breaking with the same orientation across the group.” Find the paper and full list of authors in Computational Biology.

‘Interceptive Abilities in Autism Spectrum Sisorder: Comparing Naturalistic and Virtual Visuomotor Tasks’
“A growing body of research reveals that autistic individuals exhibit motor coordination challenges. Multiple theoretical frameworks propose that the seemingly disparate features of autism may arise from a common underlying process: a diminished ability to make predictions. Sensorimotor skills, such as catching a ball, critically rely on predicting the ball’s trajectory as well as anticipatory coordination of the entire body. Here, we assessed four different naturalistic and virtual interception tasks with 31 neurotypical and 23 autistic children (ages 7–12).” Find the paper and full list of authors in Autism Research.

‘Spontaneous Anthropocentric Language Use in University Students’ Explanations of Biological Concepts’
“Previous research has shown that students employ intuitive thinking when understanding scientific concepts. Three types of intuitive thinking—essentialist, teleological, and anthropic thinking—are used in biology learning and can lead to misconceptions. … In this study, we examined how frequently undergraduate students across two U.S. universities (N = 807) used construal-consistent language (CCL) to explain in response to open-ended questions related to five core biology concepts (e.g., evolution), how CCL use differed by concept, and how this usage was related to misconceptions agreement.” Find the paper and full list of authors in LSE.

‘Role of Ryanodine Receptor Cooperativity in Ca 2+ Wave-Mediated Triggered Activity in Cardiomyocytes’
“Ca2+ waves are known to trigger delayed after-depolarizations that can cause malignant cardiac arrhythmias. However, modelling Ca2+ waves using physiologically realistic models has remained a major challenge. Existing models with low Ca 2+ sensitivity of ryanodine receptors(RyRs) necessitate large release currents, leading to an unrealistically large Ca2+ transient amplitude incompatible with the experimental observations. Consequently, current physiologically detailed models of delayed after-depolarizations resort to unrealistic cell architectures. … Here, we address these challenges by incorporatingRyR cooperativity into a physiologically detailed model with a realistic cell architecture.” Find the paper and full list of authors in The Journal of Physiology.

‘Climate Effects on Belowground Tea Litter Decomposition Depend on Ecosystem and Organic Matter Types in Global Wetlands’
“Patchy global data on belowground litter decomposition dynamics limit our capacity to discern the drivers of carbon preservation and storage across inland and coastal wetlands. We performed a global, multiyear study in over 180 wetlands across 28 countries and 8 macroclimates using standardized litter as measures of “recalcitrant” (rooibos tea) and “labile” (green tea) organic matter (OM) decomposition. … Our study highlights the potential for reduction in belowground OM in coastal and inland wetlands under increased warming.” Find the paper and full list of authors in Environmental Science & Technology.

‘DNA methylation correlates with transcriptional noise in response to elevated pCO2 in the eastern oyster’
“Ocean acidification significantly affects marine calcifiers like oysters, warranting the study of molecular mechanisms like DNA methylation that contribute to adaptive plasticity in response to environmental change. However, a consensus has not been reached on the extent to which methylation modules gene expression, and in turn plasticity, in marine invertebrates. In this study, we investigated the impact of pCO2 on gene expression and DNA methylation in the eastern oyster, Crassostrea virginica.” Find the paper and full list of authors in Environmental Epigenetics.

‘L1-ORF1p Nucleoprotein Can Rapidly Assume Distinct Conformations and… Bind More than One Nucleic Acid’
“LINE-1 (L1) is a parasitic retrotransposable DNA element, active in primates for the last 80–120 Myr. L1 has generated nearly one-third of the human genome by copying its transcripts, and those of other genetic elements. … We used optical tweezers to examine ORF1p binding to individual single-stranded DNA (ssDNA) molecules and found that the arrangement of ORF1p on the ssDNA depends on their molar ratio. … Our results suggest that ORF1p displaced from its RNA template during TPRT could bind and destabilize remaining downstream L1 RNP.”Find the paper and full list of authors in Nucleic Acids Research.

‘Self-Consistent Evaluation of Proximity and Inverse Proximity Effects With Pair-Breaking in Diffusive Superconducting–Normal Metal Junctions’
“We consider a planar superconducting–normal metal junction with both inelastic and spin-flip scattering processes present. …We use a one-dimensional formulation of the Usadel equation to compute the self-consistent energy dependence of the single-particle density of states as a function of distance from the interface on both the superconducting and metallic sides for various spatial profiles of a pair-breaking spin-flip term. The pair-breaking processes fill in the superconducting gap at zero energy, which is reflected in the zero-bias tunneling conductance in scanning tunneling microscopy/spectroscopy experiments, in the vicinity of the junction.” Find the paper and authors in Physical Review B.
