The magnitude of legal wildlife trade and implications for species survival.

The unsustainable use of wildlife is a primary driver of global biodiversity loss. No comprehensive global dataset exists on what species are in trade, their geographic origins, and trade's ultimate impacts, which limits our ability to sustainably manage trade. The United States is one of the world's largest importers of wildlife, with trade data compiled in the US Law Enforcement Management Information System (LEMIS).

Exploring the Nexus Between Emulsifier Characteristics and Typhimurium Viability in Oil-in-Water Emulsions.

Molecular characteristics of emulsifiers such as their molecular weight (MW) and surface charge, not only affect the stability of the emulsion but also can have an impact on its capacity to either inhibit or promote microbial proliferation. These characteristics can affect the behavior of pathogens such as Typhimurium in emulsion systems. The growth and thermal resistance of .

Transient Receptor Potential Vanilloid 4 Calcium-Permeable Channel Contributes to Valve Stiffening in Aortic Stenosis.

Background: Aortic valve stenosis (AVS) is a progressive disease characterized by fibrosis, inflammation, calcification, and stiffening of the aortic valve leaflets, leading to disrupted blood flow. If untreated, AVS can progress to heart failure and death within 2 to 5 years. Uncovering the molecular mechanisms behind AVS is key for developing effective noninvasive therapies.

Characterizing the Modulation and Activation-Triggering Mechanisms of Main-Belt Comets via 3D Thermophysical Modeling of an Ellipsoidal Body.

Main-belt objects (MBOs) with volatile components provide important insights into the solar system's evolution and the origin of Earth's water. In this study, we employ a 3D thermophysical model to simulate the evolution of a representative ellipsoidal main-belt comet (MBC) and investigate the factors influencing its gas and dust activity. Our results highlight the important role of large obliquities in amplifying the detectability of sublimation-driven dust emission in MBCs.

Alevin-fry-atac enables rapid and memory frugal mapping of single-cell ATAC-seq data using virtual colors for accurate genomic pseudoalignment.

Ultrafast mapping of short reads to transcriptomic and metagenomic references via lightweight mapping techniques such as pseudoalignment has demonstrated success in substantially accelerating several types of analyses without much loss in accuracy compared to alignment-based approaches. The application of pseudoalignment to large reference sequences - like the genome - is, however, not trivial, due to the large size of the references or "targets" (i.e.

The emergence of nonlinear evolutionary trade-offs and the maintenance of genetic polymorphisms.

Evolutionary models of quantitative traits often assume trade-offs between beneficial and detrimental traits, requiring modellers to specify a function linking trait values. The choice of trade-off function can be consequential; functions that assume diminishing returns (accelerating costs) typically lead to single equilibrium genotypes, while decelerating costs often lead to genetic polymorphisms. Despite their importance, our current theory has little to say on which trade-off functions are the most biologically plausible.

Distributed Acoustic Sensing for Future Planetary Applications: Initial Results From the San Francisco Volcanic Field, a Lunar Analogue.

Seismic imaging is one of the most powerful tools available for constraining the internal structure and composition of planetary bodies as well as enabling our understanding planetary evolution, geology, and distribution of natural resources. However, traditional seismic instrumentation can be heavy and voluminous, expensive, and/or difficult to rapidly deploy in large numbers. Distributed acoustic sensing (DAS) provides a promising new alternative given the ease of deployment, light weight and simplicity of fiber optic cables.

Environmental Changes Recorded in Sedimentary Rocks in the Clay-Sulfate Transition Region in Gale Crater, Mars: Results From the Sample Analysis at Mars-Evolved Gas Analysis Instrument Onboard the Mars Science Laboratory Rover.

The rover explored the region between the orbitally defined phyllosilicate-bearing Glen Torridon trough and the overlying layered sulfate-bearing unit, called the "clay-sulfate transition region." Samples were drilled from the top of the fluviolacustrine Glasgow member of the Carolyn Shoemaker formation (CSf) to the eolian Contigo member of the Mirador formation (MIf) to assess in situ mineralogical changes with stratigraphic position. The Sample Analysis at Mars-Evolved Gas Analysis (SAM-EGA) instrument analyzed drilled samples within this region to constrain their volatile chemistry and mineralogy.

Juno Observations Set New Constraints on the Electrodynamic Interaction Between Io and Jupiter.

Juno's highly elliptical polar orbits provide unprecedented in-situ observations of the electrodynamic interaction between Jupiter and its volcanic moon Io. These observations occur in regions never sampled before both near Io's orbit and near Jupiter's ionosphere and at distances between the two. Magnetic field data obtained during multiple traversals of magnetic field lines mapping to Io's orbit reveal remarkably rich and complex magnetic signatures near flux tubes connected to Io's orbital position.

Evidence of Magnetic Reconnection in Ganymede's Wake Region From Juno.

Magnetic reconnection has been commonly reported between the solar wind IMF and the magnetic field of Earth and other planets. A similar phenomenon is expected between Jupiter's magnetosphere and Ganymede's mini magnetosphere inside the Jovian magnetosphere. This article is the first report of a reconnection event in the tail region of Ganymede.

Increases in employment over six months following Khanya: A secondary analysis of a pilot randomized controlled trial of a peer-delivered behavioral intervention for substance use and HIV medication adherence in Cape Town, South Africa.

Introduction: Evidence suggests that brief, skills-based behavioral interventions are effective at improving clinical outcomes related to substance use and HIV, but little data exists on whether such interventions can incidentally improve employment. We examined preliminary changes in employment over six months following Khanya, a brief peer-delivered behavioral intervention to reduce substance use and improve antiretroviral therapy (ART) adherence compared to enhanced treatment as usual (ETAU).

Methods: Adults living with HIV (N = 61) with at least moderate substance use and ART non-adherence were recruited from a primary care clinic in Khayelitsha, South Africa, a community with high rates of unemployment.

Matching patients to clinical trials with large language models.

Patient recruitment is challenging for clinical trials. We introduce TrialGPT, an end-to-end framework for zero-shot patient-to-trial matching with large language models. TrialGPT comprises three modules: it first performs large-scale filtering to retrieve candidate trials (TrialGPT-Retrieval); then predicts criterion-level patient eligibility (TrialGPT-Matching); and finally generates trial-level scores (TrialGPT-Ranking).

Light-activatable minimally invasive ethyl cellulose ethanol ablation: Biodistribution and potential applications.

While surgical resection is a mainstay of cancer treatment, many tumors are unresectable due to stage, location, or comorbidities. Ablative therapies, which cause local destruction of tumors, are effective alternatives to surgical excision in several settings. Ethanol ablation is one such ablative treatment modality in which ethanol is directly injected into tumor nodules.

Aerobic Training Attenuates Differences Between Black and White Adults in Left Ventricular-Vascular Coupling and Wasted Pressure Effort.

Background: Black compared with White adults have a higher risk for left-ventricular hypertrophy and heart failure possibly due to the early onset of alterations in ventricular-vascular coupling (ie, arterial [] to ventricular elastance [] ratio) and wasted pressure effort (). Aerobic training preserves the coupling ratio (/) and attenuates , but whether this applies to Black adults is unknown. We hypothesized that Black rather than White adults would have greater training-induced improvements in the / and .

Cellular-resolution optogenetics reveals attenuation-by-suppression in visual cortical neurons.

The relationship between neurons' input and spiking output is central to brain computation. Studies in vitro and in anesthetized animals suggest that nonlinearities emerge in cells' input-output (IO; activation) functions as network activity increases, yet how neurons transform inputs in vivo has been unclear. Here, we characterize cortical principal neurons' activation functions in awake mice using two-photon optogenetics.

Trainees' perspectives and recommendations for catalyzing the next generation of NeuroAI researchers.

At this critical juncture in the development of NeuroAI, we outline challenges and training needs of junior researchers working across AI and neuroscience. We also provide advice and resources to help trainees plan their NeuroAI careers.

Developmental Social Experience Changes Behavior in a Threatening Environment in Catfish.

Coordinated responses to threats are important for predator evasion in many species. This study examines the effect of developmental social experience on antipredator behavior and group cohesion in a highly gregarious catfish that communicates via tactile interaction, We reared fish either in a mixed-age group of age-matched peers and adult (mixed-age condition, or MAC), or with age-matched peers only (same-age condition, or SAC). A startle test was conducted with small groups of subadults from either social rearing condition.

Resilience and strengths in the Black autism community in the United States: A scoping review.

Gaps in research knowledge pertaining to resiliency factors and strengths among the Black autism community, inclusive of autistic persons and their support system exist. A scoping review was conducted to further explore quantitative, qualitative, and mixed methods studies that investigate resiliency factors and related strengths in the Black autism community in the United States. A total of 436 articles were identified, with 28 studies included in the final review.

Orbitofrontal cortex to dorsal striatum circuit is critical for incubation of oxycodone craving after forced abstinence.

Relapse is a major challenge in treating opioid addiction, including oxycodone. During abstinence, oxycodone seeking progressively increases, a phenomenon termed incubation of oxycodone craving. We previously demonstrated a causal role of orbitofrontal cortex (OFC) in this incubation.
