Figure 9 in REVIEW Exploring annelids in the age of Enlightenment and beyond: classification and bioluminescence
Figure 9. Known geographical distribution of the bioluminescent Siberian enchytraeid Fridericia heliota Zalesskaja, 1990 (from now on, Pallas's worm). Star indicates record by P. S. Pallas in August 1772. Dots indicate type locality and subsequent records by V. N. Petushkov and N. S. Rodionova (cited by Rota et al., 2018).
Figure 6. Plate 1 in REVIEW Exploring annelids in the age of Enlightenment and beyond: classification and bioluminescence
Figure 6. Plate 1 of Müller (1771), showing his Nais proboscidea or 'gezüngelte Naide' (now Stylaria lacustris). In subfigure2, the entire worm is shown in microscopic detail and recognized as a chain of five zooids in various stages of development.
Figure 3 in REVIEW Exploring annelids in the age of Enlightenment and beyond: classification and bioluminescence
Figure 3. Plate XCII of Rösel von Rosenhof (1755), showing the 'little snakes of Mercury' [now Ophidonais serpentina (Müller, 1774)], a non-swimming worm species often seen coiled around the roots of duckweed, resembling the staff carried by Mercury, and capable of architomic regeneration.
Figure 1 in REVIEW Exploring annelids in the age of Enlightenment and beyond: classification and bioluminescence
Figure 1. Plate LXXVIII of Rösel von Rosenhof (1755), showing the 'small water snake with a long tongue-like tentacle' [now Stylaria lacustris (Linnaeus, 1758)]. In subfigures 15–18, the worm is shown free-swimming or caught by the tentacles of an 'orangeyellow polyp with long horn-shaped arms' (the brown hydra, Hydra oligactis Pallas, 1766). Worms in paratomic division, such as that illustrated in subfigure 17, were misinterpreted as the conjunction of individuals for either beneficial or aggressive purposes.

Figure 7 in REVIEW Exploring annelids in the age of Enlightenment and beyond: classification and bioluminescence
Figure 7. Dritte Tabelle of Müller (1771). Figures IV and V show the 'Faden-Würm' or 'Lumbricus lineatus' [now Lumbricillus lineatus (Müller, 1774)], at natural and magnified size.
Figure 4 in REVIEW Exploring annelids in the age of Enlightenment and beyond: classification and bioluminescence
Figure 4. Plate XCIII of Rösel von Rosenhof (1755), showing two other types of 'little snakes' (i.e. microdriles) differentiated by him. The top half (subfigures 1–7) shows the 'little maggot-like snake' [now Chaetogaster diaphanus (Gruithuisen, 1828)], a predator species feeding on water fleas; these worms survived when cut transversely but did not regrow significantly. The bottom half (subfigures 8–16) shows the 'small sinuous water snakes with two fork tips' [now Aulophorus furcatus (Müller, 1774)], which were commonly seen sitting on the duckweed and swimming away immediately if disturbed. When cut into two parts, this worm, to Rösel's amazement, regenerated into three parts: the rear part always fell into two parts (by fission of a paratomic specimen).

Behavioral trajectories of aging prairie voles (Microtus ochrogaster): Adapting behavior to social context wanes with advanced age
<p>Several studies using mice have examined the effects of aging on cognitive tasks, as well as sensory and motor functions. However, few studies have examined the influence of aging on social behavior. Prairie voles (<em>Microtus ochrogaster</em>) are a socially monogamous and biparental rodent that live in small family groups and are now among the most popular rodent models for studies examining social behavior. Although the social behavioral trajectories of early-life development in prairie voles have been well-studied, how social behavior may change throughout adulthood remains unknown. Here we examined behavior in virgin male and female prairie voles in four different age groups: postnatal day (PND) 60–80, 140–160, 220–240, and 300–320. All animals underwent testing in a novel object task, a dominance test, a resident-intruder test, and several iterations of social approach and social interaction tests with varying types of social stimuli (i.e., novel same-sex conspecific, novel opposite-sex conspecific, familiar same-sex sibling/cagemate, small group of novel same-sex conspecifics). We found that age influenced neophobia and dominance, but not social approach behavior. Further, we found that young adult, but not older adult, prairie voles adapt prosocial and aggressive behavior relative to social context and that selective aggression occurs in relation to age even in the absence of a pair bond. Our results suggest that prairie voles calibrate social phenotype in a context-dependent manner in young adulthood and stop adjusting behavior to social context in advanced age, demonstrating that social behavior is plastic not only throughout early development but also well into adulthood. Together, this study provides insight into age-related changes in social behavior in prairie voles and shows that prairie voles may be a viable model for studying the cognitive and physiological benefits of social relationships and social engagement in advanced age.</p>

If you use this dataset, please cite the manuscript in order to fairly acknowledge the contribution of all participating studies and their sponsors.</p> <p>Data consists of three gzipped files corresponding to genome-wide association meta-analysis (GWAMA) of three IgG N-glycome traits describing the percentage of galactosylation: G0, G1 and G2. The files are tab-separated and contain genome-wide association meta-analysis data for the discovery studies. Summary data are given for the meta-analyses of over 15 million directly genotyped or imputed single variant polymorphisms corresponding to the HRC (Haplotype Reference Consortium) r1.1 reference panel. Meta-analysis estimates are corrected for inflation of test statistics using genomic control at the individual study level.</p>
Evolutionary and plastic variation in larval growth and digestion reveal the complex underpinnings of size and age at maturation in dung beetles
<p>Age and size at maturity are key life history components, yet the proximate underpinnings that mediate intra- and interspecific variation in life history remain poorly understood. We studied the proximate underpinnings of species differences and nutritionally plastic variation in adult size and development time in four species of dung beetles. Specifically, we investigated how variation in insect growth mediates adult size variation, tested whether fast juvenile growth trades-off with developmental stability in adult morphology, and quantified plastic responses of digestive systems to variation in food quality. Contrary to the common size-development time trade-off, the largest species exhibited by far the shortest development time. Correspondingly, species diverged strongly in the shape of growth trajectories. Nutritionally plastic adjustments to growth were qualitatively similar between species but differed in magnitude. Although we expected rapid growth to induce developmental costs, neither instantaneous growth rates nor the duration of larval growth were related to developmental stability in the adult. This renders the putative costs of rapid growth enigmatic. We further found that larvae that encounter a challenging diet develop a larger midgut and digest more slowly than animals reared on a more nutritious diet. These data are consistent with the hypothesis that larvae invest into a more effective digestive system when exposed to low-quality nutrition, but suggest that species may diverge readily in their reliance on these mechanisms. More generally, our data highlight the complex, and often hidden, relationships between immature growth and age and size at maturation even in ecologically similar species.</p>
Portable ultrasound technologies for estimating gestational age in pregnant women: A scoping review and analysis of commercially available models
<p><strong>Objectives</strong>: To identify all available studies assessing the use of portable ultrasound devices for pregnant women, with the specific aim of finding evidence for devices used to determine gestational age and their validity when compared to conventional ultrasound machines. We also wanted to determine what portable ultrasound models are commercially available for obstetric use. </p> <p><strong>Design</strong>: Systematic scoping review</p> <p><strong>Primary and secondary outcome measures:</strong> Extracted variables included study design, population, method of ultrasound measurement, devices used and whether studies formally validated accuracy against conventional ultrasound</p> <p><strong>Results</strong>: We searched four databases – Medline, Embase, CINAHL, and Maternal and Infant Care. In total, 56 studies from 34 countries were identified; most were observational studies. Across all studies, 27 different portable ultrasound models (from 17 manufacturers) were evaluated. Twenty-one studies assessed use of portable ultrasound for evaluating fetal characteristics or estimating gestational age, and 10 of these were formal validation studies. In total, six portable devices have been validated for gestational age estimation against a conventional ultrasound comparator. The web searches identified 102 portable devices (21 manufacturers). These were a mix of handheld devices that connected to a phone or computer, or laptop-style portable ultrasound devices. Prices ranged from $1,190 to $30,000 USD and weight ranged from 0.9 kg to 13.0 kg.</p> <p><strong>Conclusion</strong>: While the number of commercially available portable ultrasound devices continues to grow, there remains a lack of peer-reviewed, quality evidence demonstrating their accuracy and validity when compared to conventional ultrasound machines. This review identified some models that may be useful in gestational age estimation in low-resource settings, but more research is required to help implement the technology at scale.</p>
