Basophils are derived from the same stem cell line as mast cells and while they are similar to mast cells, they are not identical (they are thought by some to be immature mast cells). They are the least common of all the leukocytes, are a similar size to neutrophils and eosinophils and are characterised by the large number of basophilic staining granules in their cytoplasm. They are present in the circulation but rarely found in tissue.

Deputy U.S. Marshal Bass Reeves was a highly respected and wildly successful peace officer in Indian Territory for over thirty years, starting when he was first commissioned by federal Judge Isaac Parker in 1875. His life saw the enormous transformations that swept through the country during the Civil War, the days of the “wild west” in the federal territories, and the final settling of the frontier. The exploits of Deputy Marshal Reeves as he fought and captured hundreds of outlaws made him famous in his own time. This lesson tells the story of Reeves, his world, and his relentless pursuit of justice. The Woodson Center's Black History and Excellence curriculum is based on the Woodson Principles and tells the stories of Black Americans whose tenacity and resilience enabled them to overcome adversity and make invaluable contributions to our country. It also teaches character and decision-making skills that equip students to take charge of their futures. These lessons in Black American excellence are free and publicly available for all.

"Bathyarchaeota is a newly proposed phylum of archaeal organisms. Its diverse members inhabit anoxic environments such as hot springs, salt marshes, mangrove sediments, and the sub-seafloor. While Bathyarchaeota is believed to be an important driver of the global carbon cycle, little is known about the phylum's true metabolic potential. A new study constructed nine metagenome-assembled genomes of Bathyarchaeota using mangrove and mudflat sediments of the Futian and Mai Po Nature Reserves. Comparative analyses of these genomes expanded the role of this phylum in phototrophy, autotrophy, and the nitrogen and sulfur cycles. and findings suggested the Bathyarchaeotal subgroup can sense light and thrive in micro-oxygen conditions. The results provide insight into the metabolic abilities and diverse lifestyles of members of Bathyarchaeota and highlight the crucial role of this newly proposed phylum in global biochemical cycles..."

"Two mosquito species in America have been engaged in a battle for dominance for the past 30 years: the native Aedes aegypti and the invasive Aedes albopictus -- also known as the Asian tiger mosquito The tiger mosquito has a distinct competitive advantage Male Aedes albopictus are really good at wooing female Aedes aegypti The resultant interspecies mating permanently sterilizes the female, effectively ending her reproductive future But Aedes aegypti are evolving the ability to resist the advances of Aedes albopictus Although this is good news for Aedes aegypti the outlook is darker for humans, as Aedes aegypti are key transmitters of diseases like Zika and dengue fever Researchers have now started to uncover the genetic changes tied to this resistance Uncovering the molecular correlates governing mosquito mating preferences could lead to better control strategies and might help prevent future outbreaks of disease Burford Reiskind, et al..."

In 2016, a billionaire businessman and the first woman nominated by a major party ran against each other for president of the United States. In very different ways, both candidates approached the presidency as outsiders, reaching beyond the traditional boundaries of US presidential politics. As outsiders, the 2016 candidates are noteworthy, but not unique; indeed, the 2016 race resonates with the legacies of outsiders who have come before. This exhibition explores the rich history of select individuals, parties, events, and movements that have influenced US presidential elections from the outside—outside Washington politics, outside the two-party system, and outside the traditional conception of who can be an American president.

We revisit the results of the recent Reproducibility Project: Psychology by the Open Science Collaboration. We compute Bayes factors—a quantity that can be used to express comparative evidence for an hypothesis but also for the null hypothesis—for a large subset (N = 72) of the original papers and their corresponding replication attempts. In our computation, we take into account the likely scenario that publication bias had distorted the originally published results. Overall, 75% of studies gave qualitatively similar results in terms of the amount of evidence provided. However, the evidence was often weak (i.e., Bayes factor < 10). The majority of the studies (64%) did not provide strong evidence for either the null or the alternative hypothesis in either the original or the replication, and no replication attempts provided strong evidence in favor of the null. In all cases where the original paper provided strong evidence but the replication did not (15%), the sample size in the replication was smaller than the original. Where the replication provided strong evidence but the original did not (10%), the replication sample size was larger. We conclude that the apparent failure of the Reproducibility Project to replicate many target effects can be adequately explained by overestimation of effect sizes (or overestimation of evidence against the null hypothesis) due to small sample sizes and publication bias in the psychological literature. We further conclude that traditional sample sizes are insufficient and that a more widespread adoption of Bayesian methods is desirable.

Bayesian hypothesis testing presents an attractive alternative to p value hypothesis testing. Part I of this series outlined several advantages of Bayesian hypothesis testing, including the ability to quantify evidence and the ability to monitor and update this evidence as data come in, without the need to know the intention with which the data were collected. Despite these and other practical advantages, Bayesian hypothesis tests are still reported relatively rarely. An important impediment to the widespread adoption of Bayesian tests is arguably the lack of user-friendly software for the run-of-the-mill statistical problems that confront psychologists for the analysis of almost every experiment: the t-test, ANOVA, correlation, regression, and contingency tables. In Part II of this series we introduce JASP (http://www.jasp-stats.org), an open-source, cross-platform, user-friendly graphical software package that allows users to carry out Bayesian hypothesis tests for standard statistical problems. JASP is based in part on the Bayesian analyses implemented in Morey and Rouder’s BayesFactor package for R. Armed with JASP, the practical advantages of Bayesian hypothesis testing are only a mouse click away.

Mature B cells that undergo stimulation by an antigen undergo class switching, and differentiate into either plasma or memory cells. In the paracortex region of the lymph node binding to MHC II in the presence of IL-4 produced by the CD4+ T cells (TH2 type) causes the B cells to differentiate; most will become plasma cells, however a small number will become memory cells. Follicular dendritic cells present in the germinal centers of peripheral lymphoid organs can absorb intact antigen onto their surface to present to B cells to stimulate differentiation.

Media literacy includes the practices that allow people to access, critically evaluate and create media. We intend to promote awareness of media influence and create an active stance towards both consuming and creating media. We want to develop receptive media capability to critically analyze messages, offer opportunities for students to broaden their experience of media, and help them develop generative media capability to increase creative skills in making their own media messages and also fight with fake news.
