UCSD's Microgrid: A Pattern for Future Energy Generation?
Climate change is an urgent and pressing issue, as temperatures rise due to excessive carbon dioxide emissions, as well as short lived climate pollutants (black carbon, methane, hydrofluorocarbons, and tropospheric ozone) nations are beginning toexperience the consequences of climate change. The Bending the Curve Report states that mitigating short- lived climate pollutants (SLCPs) may reduce warming by 0.6 degrees Celsius, allowing the world to implement zero emission technology (Ramanathan et al; pg. 5). According to the report, an 80% reduction in carbon emissions, along with SLCP mitigation action, will maintain global warming below 2 degrees Celsius for the rest of the century (Ramanathan et al; pg. 14). Replacing natural gas with renewable energy will be essential to becoming carbon neutral, this will benefitnot only developed cities but reduce the need for SLCPs in rural and developing areas as well. UCSD is taking initiative through development of its microgrid, allowing the ability to produce our own energy and create independence from the main grid

Once a feminist: Lynne Segal on Grace Paley’s The Little Disturbances of Man
The following contributions came in response to a request, sent to a number of key figures in feminism today, to write on a text that had been formative for their thinking as feminists. The chosen text could be a theory, a novel, an artwork, a performance, a poem: one that had stimulated, or even revolutionised, their ideas. As we hoped, this project has created a selection of texts central to our many and different experiences as feminists.
I used to say that Margaret Drabble's The Garrick Year was the story of my life, in my early twenties, as if I was just a creature of time and circumstance. I read The Garrick Year sometime between October 1965, when my first child was born, and the end of 1967, before my marriage disintegrated. Like the heroine Emma Evans, I married a successful actor, had a child, and followed his career—which in the novel led Emma to Hereford for a summer season of plays
Tales from camp Wilde: queer(y)ing environmental education research
This paper questions the relative silence of queer theory and theorizing inenvironmental education research. We explore some possibilities for queering environmental education research by fabricating (and inviting colleagues to fabricate) stories of Camp Wilde, a fictional location that helps us to expose the facticity of the field’s heteronormative constructedness. These stories suggest alternative ways of (re)presenting and (re)producing both the subjects/objects of our inquiries and our identities as researchers. The contributors draw on a variety of theoretical resources from art history, deconstruction, ecofeminism, literary criticism, popular cultural studies, and feminist poststructuralism to perform an orientation to environmental education research that we hope will never be arrested by its categorization as a “new genre.”<br /

Immunopathological signatures in multisystem inflammatory syndrome in children and pediatric COVID-19
: Pediatric Coronavirus Disease 2019 (pCOVID-19) is rarely severe; however, a minority of children infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) might develop multisystem inflammatory syndrome in children (MIS-C), with substantial morbidity. In this longitudinal multi-institutional study, we applied multi-omics (analysis of soluble biomarkers, proteomics, single-cell gene expression and immune repertoire analysis) to profile children with COVID-19 (n = 110) and MIS-C (n = 76), along with pediatric healthy controls (pHCs; n = 76). pCOVID-19 was characterized by robust type I interferon (IFN) responses, whereas prominent type II IFN-dependent and NF-κB-dependent signatures, matrisome activation and increased levels of circulating spike protein were detected in MIS-C, with no correlation with SARS-CoV-2 PCR status around the time of admission. Transient expansion of TRBV11-2 T cell clonotypes in MIS-C was associated with signatures of inflammation and T cell activation. The association of MIS-C with the combination of HLA A*02, B*35 and C*04 alleles suggests genetic susceptibility. MIS-C B cells showed higher mutation load than pCOVID-19 and pHC. These results identify distinct immunopathological signatures in pCOVID-19 and MIS-C that might help better define the pathophysiology of these disorders and guide therapy
Enrichment of putative PAX8 target genes at serous epithelial ovarian cancer susceptibility loci
Background: Genome-wide association studies (GWAS) have identified 18 loci associated with serous ovarian cancer (SOC) susceptibility but the biological mechanisms driving these findings remain poorly characterised. Germline cancer risk loci may be enriched for target genes of transcription factors (TFs) critical to somatic tumorigenesis.
Methods: All 615 TF-target sets from the Molecular Signatures Database were evaluated using gene set enrichment analysis (GSEA) and three GWAS for SOC risk: discovery (2196 cases/4396 controls), replication (7035 cases/21 693 controls; independent from discovery), and combined (9627 cases/30 845 controls; including additional individuals).
Results: The PAX8-target gene set was ranked 1/615 in the discovery (PGSEA<0.001; FDR=0.21), 7/615 in the replication (PGSEA=0.004; FDR=0.37), and 1/615 in the combined (PGSEA<0.001; FDR=0.21) studies. Adding other genes reported to interact with PAX8 in the literature to the PAX8-target set and applying an alternative to GSEA, interval enrichment, further confirmed this association (P=0.006). Fifteen of the 157 genes from this expanded PAX8 pathway were near eight loci associated with SOC risk at P<10−5 (including six with P<5 × 10−8). The pathway was also associated with differential gene expression after shRNA-mediated silencing of PAX8 in HeyA8 (PGSEA=0.025) and IGROV1 (PGSEA=0.004) SOC cells and several PAX8 targets near SOC risk loci demonstrated in vitro transcriptomic perturbation.
Conclusions: Putative PAX8 target genes are enriched for common SOC risk variants. This finding from our agnostic evaluation is of particular interest given that PAX8 is well-established as a specific marker for the cell of origin of SOC
Height, selected genetic markers and prostate cancer risk:Results from the PRACTICAL consortium
Background: Evidence on height and prostate cancer risk is mixed, however, recent studies with large data sets support a
possible role for its association with the risk of aggressive prostate cancer.
Methods: We analysed data from the PRACTICAL consortium consisting of 6207 prostate cancer cases and 6016 controls and a
subset of high grade cases (2480 cases). We explored height, polymorphisms in genes related to growth processes as main effects
and their possible interactions.
Results: The results suggest that height is associated with high-grade prostate cancer risk. Men with height 4180cm are at a 22%
increased risk as compared to men with height o173cm (OR 1.22, 95% CI 1.01–1.48). Genetic variants in the growth pathway gene
showed an association with prostate cancer risk. The aggregate scores of the selected variants identified a significantly increased
risk of overall prostate cancer and high-grade prostate cancer by 13% and 15%, respectively, in the highest score group as
compared to lowest score group.
Conclusions: There was no evidence of gene-environment interaction between height and the selected candidate SNPs. Our
findings suggest a role of height in high-grade prostate cancer. The effect of genetic variants in the genes related to growth is
seen in all cases and high-grade prostate cancer. There is no interaction between these two exposures.</p
Evaluation of Candidate Stromal Epithelial Cross-Talk Genes Identifies Association between Risk of Serous Ovarian Cancer and TERT, a Cancer Susceptibility “Hot-Spot”
We hypothesized that variants in genes expressed as a consequence of interactions between ovarian cancer cells and the host micro-environment could contribute to cancer susceptibility. We therefore used a two-stage approach to evaluate common single nucleotide polymorphisms (SNPs) in 173 genes involved in stromal epithelial interactions in the Ovarian Cancer Association Consortium (OCAC). In the discovery stage, cases with epithelial ovarian cancer (n = 675) and controls (n = 1,162) were genotyped at 1,536 SNPs using an Illumina GoldenGate assay. Based on Positive Predictive Value estimates, three SNPs—PODXL rs1013368, ITGA6 rs13027811, and MMP3 rs522616—were selected for replication using TaqMan genotyping in up to 3,059 serous invasive cases and 8,905 controls from 16 OCAC case-control studies. An additional 18 SNPs with Pper-allele<0.05 in the discovery stage were selected for replication in a subset of five OCAC studies (n = 1,233 serous invasive cases; n = 3,364 controls). The discovery stage associations in PODXL, ITGA6, and MMP3 were attenuated in the larger replication set (adj. Pper-allele≥0.5). However genotypes at TERT rs7726159 were associated with ovarian cancer risk in the smaller, five-study replication study (Pper-allele = 0.03). Combined analysis of the discovery and replication sets for this TERT SNP showed an increased risk of serous ovarian cancer among non-Hispanic whites [adj. ORper-allele 1.14 (1.04–1.24) p = 0.003]. Our study adds to the growing evidence that, like the 8q24 locus, the telomerase reverse transcriptase locus at 5p15.33, is a general cancer susceptibility locus
