Effective spatial visualization and reasoning skills are often credited for students' success in science and engineering courses. However, students enrolled in these science courses are not always exposed to or trained properly on the best ways to utilize models to aid in their learning. Improving spatial visualization techniques with 3D models, such as molecular and DNA modeling kits, is often suggested to facilitate students' ability to conceptualize compounds in two and three dimensions.

Gastrotheca Fitzinger, 1843 tadpole morphology: Larval cranium description and its evolutionary implications (Amphibia: Anura: Hemiphractidae).

J Morphol

September 2024

Leibniz Institut zur Analyse des Biodiversitätswandels, Zoologisches Museum Hamburg, Zentrum für Taxonomie und Morphologie, Hamburg, Germany.

Hemiphractids have a singular mode of reproduction that involves maternal care. The Andean-endemic Gastrotheca marsupiata species group includes direct-developing and tadpole-bearing species, the latter trait being unique among Gastrotheca. Larval morphology has proven to be a valuable source of evidence to understand the taxonomy and evolution of frogs but remains understudied in Hemiphractids.

Background: Patients with significant multimorbidity and other factors that make healthcare challenging to access and coordinate are at high risk for poor health outcomes. Although most (93%) of Veterans' Health Administration (VHA) patients at high risk for hospitalization or death ("high-risk Veterans") are primarily managed by primary care teams, few of these teams have implemented evidence-based practices (EBPs) known to improve outcomes for the high-risk patient population's complex healthcare issues. Effective implementation strategies could increase adoption of these EBPs in primary care; however, the most effective implementation strategies to increase evidence-based care for high-risk patients are unknown.

Evidence supports the efficacy of Behavioral Parent Training (BPT) interventions such as Parent-Child Interaction Therapy (PCIT) for treating child behavior problems; however, treatment engagement and outcomes vary across ethnic groups. Risk for poor treatment engagement and outcomes may be attributed in part to misalignment between parent explanatory model components (PEMs) and the traditional BPT model, including treatment expectations, etiological explanations, parenting styles, and family support for treatment. The present study aims to examine whether personalized treatment adaptations addressing these PEM-BPT misalignments reduce risk for poor treatment engagement and outcomes.

Concentrations of selenium that exceed regulatory guidelines have been associated with coal mining activities and have been linked to detrimental effects on aquatic ecosystems and the organisms therein. Although the major route of selenium uptake in macroinvertebrates is via the diet, the uptake of waterborne selenite (HSeO), the prominent form at circumneutral pH, can be an important contributor to selenium body burden and thus selenium toxicity. In the current study, radiolabelled selenite (Se) was used to characterize the mechanism of selenite uptake in the water flea, .

Northern peatlands store approximately one-third of terrestrial soil carbon. Climate warming is expected to stimulate the microbially mediated degradation of peat soil organic matter (SOM), leading to increasing greenhouse gas (GHG; carbon dioxide, CO2; methane, CH4) production and emission. Porewater dissolved organic matter (DOM) plays a key role in SOM decomposition; however, the mechanisms controlling SOM decomposition and its response to warming remain unclear.

Paleoecological evidence for environmental specialization in Paranthropus boisei compared to early Homo.

J Hum Evol

April 2023

Department of Anthropology, University of Utah, 260 South Central Campus Drive, Salt Lake City, UT 84112, USA; Natural History Museum of Utah, University of Utah, 301 Wakara Way, Salt Lake City, UT 84108, USA; Origins Centre, University of the Witwatersrand, 1 Jan Smuts Avenue, Braamfontein 2000, Johannesburg, South Africa.

Since the discovery of Paranthropus boisei alongside early Homo at Olduvai Gorge and East Turkana, paleoanthropologists have attempted to understand the different evolutionary paths of these two hominin lineages. Conventional wisdom is that their prolonged phase of sympatry in eastern Africa reflects different adaptive strategies, with early Homo characterized as the ecologically flexible generalist and Paranthropus as the less versatile specialist. If correct, this should imply differences in their use of ancient environments, with early Homo occurring in a broader range of environmental contexts than Paranthropus.

Personalizing PCIT for culturally diverse families: Outcomes from a pilot trial utilizing the PersIn framework.

Behav Res Ther

December 2022

Child and Adolescent Services Research Center, USA; University of San Diego, 5998 Alcala Park, San Diego, CA, 92110, USA. Electronic address:

Culture-specific versions of evidence-based interventions are critically important to meeting the needs of underserved and minoritized populations but may also face significant barriers to large-scale implementation when there are settings with multiple cultural groups and within-group heterogeneity. The PersIn framework is a proposed approach for personalizing an evidence-based intervention to facilitate cultural responsiveness concurrent with fidelity to the original intervention, flexibility in individual implementation, and administration that is standardized, feasible, and replicable. This study describes pilot feasibility outcomes for MY PCIT (n = 32), a personalized version of Parent-Child Interaction Therapy for culturally diverse families that was developed as a proof-of-concept of the PersIn framework.

Dengue is a viral disease that primarily affects tropical and subtropical regions and is especially prevalent in South-East Asia. This mosquito-borne disease sometimes triggers nationwide epidemics, which results in a large number of fatalities. The development of Dengue Haemorrhagic Fever (DHF) is where most cases occur, and a large portion of them are detected among children under the age of ten, with severe conditions often progressing to a critical state known as Dengue Shock Syndrome (DSS).

Beetle bioluminescence outshines extant aerial predators.

Proc Biol Sci

July 2022

Department of Biology and Monte L. Bean Museum, Brigham Young University, 4102 LSB, Provo, UT 84602, USA.

We understand very little about the timing and origins of bioluminescence, particularly as a predator avoidance strategy. Understanding the timing of its origins, however, can help elucidate the evolution of this ecologically important signal. Using fireflies, a prevalent bioluminescent group where bioluminescence primarily functions as aposematic and sexual signals, we explore the origins of this signal in the context of their potential predators.

What Are Group Level Traits and How Do They Evolve?

Integr Psychol Behav Sci

September 2023

Center for Science, Athabasca University, 1 University Dr., T9S 3A3, Athabasca, AB, Canada.

Cultural traits are seldom atomic, are distributed over multiple social domains, and undergo differential selection. This makes it important to study the nature and evolution of these traits from a global viewpoint. This paper considers group level cultural traits-what sort of traits are there, how do they evolve, and what is the relationship between cultural traits and their representation in individual worldviews.

In conventional gases and plasmas, it is known that heat fluxes are proportional to temperature gradients, with collisions between particles mediating energy flow from hotter to colder regions and the coefficient of thermal conduction given by Spitzer's theory. However, this theory breaks down in magnetized, turbulent, weakly collisional plasmas, although modifications are difficult to predict from first principles due to the complex, multiscale nature of the problem. Understanding heat transport is important in astrophysical plasmas such as those in galaxy clusters, where observed temperature profiles are explicable only in the presence of a strong suppression of heat conduction compared to Spitzer's theory.

University of Southern California, Department of Neurology, 1520 San Pablo St. Suite 3000, Los Angeles, CA 90033, United States; University of Southern California, Department of Population and Public Health Sciences, 2001 North Soto Street, Los Angeles, CA 90033, United States of America. Electronic address:

Exposures to fine particulate matter (PM) and nitrogen dioxide (NO) have been associated with the emergence of depressive symptoms in older adulthood, although most studies used cross-sectional outcome measures. Elucidating the brain structures mediating the adverse effects can strengthen the causal role between air pollution and increasing depressive symptoms. We evaluated whether smaller volumes of brain structures implicated in late-life depression mediate associations between ambient air pollution exposure and changes in depressive symptoms.
