Science Hunters: An inclusive approach to engaging with science through Minecraft
Science Hunters is an outreach project which employs the computer game Minecraft to engage children with scientific learning and research through school visits, events, and extracurricular clubs. We principally target children who may experience barriers to accessing Higher Education, including low socioeconomic status, being the first in their family to attend university, and disability (including Special Educational Needs). The Minecraft platform encourages teamwork and makes science learning accessible and entertaining for children, irrespective of background. We employ a flexible approach that adapts to the needs of the users. More than 8000 children have been engaged in the first four years, with overwhelmingly positive feedback
Shared special interest play in a specific extra-curricular group setting: A Minecraft Club for children with Special Educational Needs
Elements of construction: Minecraft and the periodic table
Minecraft is a popular computer game that allows the construction of almost limitless creations, and is used in learning contexts around the world. The widespread appeal and familiarity of the game makes it ideal for engaging children and young people with topics that might not otherwise interest them. With this in mind, the Science Hunters project, with support from a Royal Society of Chemistry (RSC) Outreach Fund grant, developed five Minecraft-based informal learning and engagement sessions about the periodic table, carbon, helium, uranium and gold, as part of the 2019 International Year of the Periodic Table (IYPT)
Science Hunters: Teaching science concepts in schools using Minecraft
Background Science Hunters is an outreach project based at Lancaster University, UK. It uses the computer game Minecraft, alongside interactive discussion and hands-on demonstrations, to engage children with scientific research topics and science learning.Material and methodsAs part of ongoing evaluation, the efficacy of this approach as an educational intervention was tested via pre- and post-activity questionnaires for two session topics,with 492 children participating through schools in 2017 and 2018.ResultsStatistically significant mprovement in subject knowledge was seen in post-intervention scores for both topics. There was some variation in both absolute and improvement score results between boys and girls, and primary and secondary school students.ConclusionsParticipation leads to improved subject knowledge and understanding, regardless of prior existing knowledge
Using Minecraft to engage children with science at public events
Engagement with science and scientific skills is an important aspect of children's ability to navigate the world around them, but engagement with science is low in comparison with other subjects. The Lancaster University outreach project Science Hunters takes a novel approach to engaging children with environmental science research through a constructivist pedagogical approach using the popular computer game Minecraft. While Minecraft is extensively used in formal education settings, few data are available on its use in public engagement with scientific research, and the relationship between children's and adults' attitudes to science and computer games are complex. Through motivational surveys conducted as part of the project evaluation, we analysed feedback from participants who attended sessions as part of a programme at public events, to explore the basic demographics of children attending our events, and whether it is the prospect of learning about science, or the opportunity to play Minecraft that leads them to choose our activity. We also present evaluation of general feedback from participants at public events over four years to give a broader view of participants' response to the activities
Security: Collective good or commodity?
This is the author's accepted manuscript. The final published article is available from the link below. Copyright @ 2008 Sage.The state monopoly on the legitimate use of violence in Europe and North America has been central to the development of security as a collective good. Not only has it institutionalized the state as the prime national and international security provider, it has helped to reduce the threat from other actors by either prohibiting or limiting their use of violence. The recent growth of the private security industry appears to undermine this view. Not only are private security firms proliferating at the national level; private military companies are also taking over an increasing range of military functions in both national defence and international interventions. This article seeks to provide an examination of the theoretical and practical implications of the shift from states to markets in the provision of security. Specifically, it discusses how the conceptualization of security as a commodity rather than a collective good affects the meaning and implementation of security in Western democracies.ESR
Allele-Specific HLA Loss and Immune Escape in Lung Cancer Evolution
Immune evasion is a hallmark of cancer. Losing the ability to present neoantigens through human leukocyte antigen (HLA) loss may facilitate immune evasion. However, the polymorphic nature of the locus has precluded accurate HLA copy-number analysis. Here, we present loss of heterozygosity in human leukocyte antigen (LOHHLA), a computational tool to determine HLA allele-specific copy number from sequencing data. Using LOHHLA, we find that HLA LOH occurs in 40% of non-small-cell lung cancers (NSCLCs) and is associated with a high subclonal neoantigen burden, APOBEC-mediated mutagenesis, upregulation of cytolytic activity, and PD-L1 positivity. The focal nature of HLA LOH alterations, their subclonal frequencies, enrichment in metastatic sites, and occurrence as parallel events suggests that HLA LOH is an immune escape mechanism that is subject to strong microenvironmental selection pressures later in tumor evolution. Characterizing HLA LOH with LOHHLA refines neoantigen prediction and may have implications for our understanding of resistance mechanisms and immunotherapeutic approaches targeting neoantigens. Video Abstract [Figure presented] Development of the bioinformatics tool LOHHLA allows precise measurement of allele-specific HLA copy number, improves the accuracy in neoantigen prediction, and uncovers insights into how immune escape contributes to tumor evolution in non-small-cell lung cancer
Fc-Optimized Anti-CD25 Depletes Tumor-Infiltrating Regulatory T Cells and Synergizes with PD-1 Blockade to Eradicate Established Tumors
CD25 is expressed at high levels on regulatory TÂ (Treg) cells and was initially proposed as a target for cancer immunotherapy. However, anti-CD25 antibodies have displayed limited activity against established tumors. We demonstrated that CD25 expression is largely restricted to tumor-infiltrating Treg cells in mice and humans. While existing anti-CD25 antibodies were observed to deplete Treg cells in the periphery, upregulation of the inhibitory Fc gamma receptor (FcÎłR) IIb at the tumor site prevented intra-tumoral Treg cell depletion, which may underlie the lack of anti-tumor activity previously observed in pre-clinical models. Use of an anti-CD25 antibody with enhanced binding to activating FcÎłRs led to effective depletion of tumor-infiltrating Treg cells, increased effector to Treg cell ratios, and improved control of established tumors. Combination with anti-programmed cell death protein-1 antibodies promoted complete tumor rejection, demonstrating the relevance of CD25 as a therapeutic target and promising substrate for future combination approaches in immune-oncology
