Linear waste management systems are unsustainable and contribute to environmental degradation, economic inequity, and health disparities. Among the array of environmental challenges stemming from anthropogenic impacts, the management of human excrement (human feces and urine) stands as a significant concern. Over two billion people do not have access to adequate sanitation, signifying a global public health crisis.

In this editorial, we discuss the need for a new, long-term strategy for managing human excrement (feces and urine) to facilitate health equity and promote environmental sustainability. Human excrement composting (HEC), a human-directed process driven by highly variable and diverse microbiomes, provides a means to advance this need and we discuss how microbiome science can help to advance HEC research. We argue that the technological advancements that have driven the growth of microbiome science, including microbiome and untargeted metabolome profiling, can be leveraged to enhance our understanding of safe and efficient HEC.

We outline two accounts by which executive function (EF) supports children's moral reasoning: an emergence and an expression account. The emergence account postulates that EF supports the development of moral concepts because it relates to how children navigate their early social environments and how well they can internalize moral messages. The expression account postulates that EF supports children's in-the-moment moral reasoning for complex moral situations.

Vaginal dysbiosis is implicated in persistent human papillomavirus (HPV) infection and cervical cancer. Yet, there is a paucity of data on the vaginal microbiome in Native American communities. Here, we aimed to elucidate the relationships between microbiome, HPV, sociodemographic, and behavioral risk factors to better understand an increased cervical cancer risk in Native American women.

Motivation: Software is vital for the advancement of biology and medicine. Impact evaluations of scientific software have primarily emphasized traditional citation metrics of associated papers, despite these metrics inadequately capturing the dynamic picture of impact and despite challenges with improper citation.

Results: To understand how software developers evaluate their tools, we conducted a survey of participants in the Informatics Technology for Cancer Research (ITCR) program funded by the National Cancer Institute (NCI).

Supplementation with CBM588, a bifidogenic live bacterial product, has been associated with improved clinical outcomes in persons with metastatic renal cell carcinoma (mRCC) receiving nivolumab and ipilimumab. However, its effect on those receiving tyrosine kinase inhibitor-based combinations is unknown. In this open-label, randomized, investigator-initiated, phase 1 study, 30 participants with locally advanced or mRCC with histological confirmation of clear cell, papillary or sarcomatoid component were randomized in a 2:1 fashion to receive cabozantinib (an inhibitor of vascular endothelial growth factor receptor, MET and AXL) and nivolumab (anti-programmed cell death protein 1) with or without CBM588 as first-line treatment.

Background: Most seasonally circulating enteroviruses result in asymptomatic or mildly symptomatic infections. In rare cases, however, infection with some subtypes can result in paralysis or death. Of the 300 subtypes known, only poliovirus is reportable, limiting our understanding of the distribution of other enteroviruses that can cause clinical disease.

Study reproducibility is essential to corroborate, build on, and learn from the results of scientific research but is notoriously challenging in bioinformatics, which often involves large data sets and complex analytic workflows involving many different tools. Additionally, many biologists are not trained in how to effectively record their bioinformatics analysis steps to ensure reproducibility, so critical information is often missing. Software tools used in bioinformatics can automate provenance tracking of the results they generate, removing most barriers to bioinformatics reproducibility.

Environmental DNA (eDNA) metabarcoding has gained growing attention as a strategy for monitoring biodiversity in ecology. However, taxa identifications produced through metabarcoding require sophisticated processing of high-throughput sequencing data from taxonomically informative DNA barcodes. Various sets of universal and taxon-specific primers have been developed, extending the usability of metabarcoding across archaea, bacteria and eukaryotes.

Article Synopsis
  • OFS (oligofructose) supplementation in rats on a high-fat diet reduces food intake and body weight by enhancing small intestinal lipid sensing.
  • The treatment leads to increased expression of CD36, higher GLP-1 levels, and activation of hindbrain neurons related to satiation after lipid infusion.
  • Changes in the gut microbiota, particularly an increase in Bifidobacterium, play a crucial role in mediating these effects on energy homeostasis and food intake regulation.

Article Synopsis
  • The study investigates the gut microbiota-brain axis in female 3xTg-AD mice, a model for Alzheimer's disease, by analyzing fecal samples and gene expression in the colon and hippocampus over a 52-week period.
  • Researchers found distinct gut microbiota differences between 3xTg-AD mice and wild-type controls early in life, with specific immune markers elevated in both the colon and hippocampus indicating neuroinflammation.
  • The study highlights that changes in gut bacteria composition can predict the development of Alzheimer's disease pathologies, marking it as the first comprehensive analysis over an extended time frame.

Acute gastroenteritis (AGE) is a disease of global public health importance. Recent studies show that children with AGE have an altered gut microbiota relative to non-AGE controls. Yet, how the gut microbiota differs in Ghanaian children with and without AGE remains unclear.

  • Previous research indicated a link between oral microbiome diversity and lung cancer, but this study used a more robust case-cohort design to explore these associations.
  • Analysis of oral wash samples from 1306 lung cancer cases revealed that higher diversity in oral bacteria was associated with a lower risk of developing lung cancer, along with specific bacterial genera influencing risk levels.
  • Findings suggest a complex relationship between the oral microbiome and lung cancer, particularly related to smoking history and cancer type, highlighting potential avenues for lung cancer prevention strategies.

When faced with transgressions in their peer groups, children must navigate a series of situational cues (e.g., type of transgression, transgressor gender, transgressor intentionality) to evaluate the moral status of transgressions and to inform their subsequent behavior toward the transgressors.

Emerging evidence suggests that host-microbe interaction in the cervicovaginal microenvironment contributes to cervical carcinogenesis, yet dissecting these complex interactions is challenging. Herein, we performed an integrated analysis of multiple "omics" datasets to develop predictive models of the cervicovaginal microenvironment and identify characteristic features of vaginal microbiome, genital inflammation and disease status. Microbiomes, vaginal pH, immunoproteomes and metabolomes were measured in cervicovaginal specimens collected from a cohort (n = 72) of Arizonan women with or without cervical neoplasm.

Despite a global and nationwide decrease, Native Americans continue to experience high rates of cancer morbidity and mortality. Vaccination is one approach to decrease cancer incidence such as the case of cervical cancer. However, the availability of vaccines does not guarantee uptake, as evident in the Coronavirus 2019 pandemic.

  • In October 2020, a team hosted their first online workshop teaching how to use a microbiome research tool called QIIME 2, with 75 participants from 25 countries.
  • The workshop lasted 5 days and used a special online setup that allowed everyone to work together, and many instructors helped out.
  • After receiving feedback, they organized a second workshop in January 2021, made improvements based on suggestions, and planned to share what they learned for future events.

The COVID-19 pandemic has led to a rapid accumulation of SARS-CoV-2 genomes, enabling genomic epidemiology on local and global scales. Collections of genomes from resources such as GISAID must be subsampled to enable computationally feasible phylogenetic and other analyses. We present genome-sampler, a software package that supports sampling collections of viral genomes across multiple axes including time of genome isolation, location of genome isolation, and viral diversity.
