In this commentary we discuss the geopolitics over China’s Mekong dams to provide an understanding of the challenging downstream impacts of its hydropower dams. When it comes to downstream countries struggling to secure their national water security while sustaining economic and diplomatic ties with Beijing, Beijing’s actions reflect a huge mismatch between words and deeds. The relationship between Mekong riparian countries and their giant upstream neighbor is a complicated push-and-pull dynamic in which local voices and biodiversity conservation are often excluded. The growing citizen science–led collective grassroots initiatives in the Lower Mekong provide an opportunity for the downstream governments to broaden their response strategies. By analyzing the impacts of public participation in local environmental decision making and policy arenas, the article provides insights into the role of citizen science in networking science and grassroots movements to oppose ill-conceived projects in constructive and peaceful manners. It concludes with a discussion on how citizen science–led grassroots environmental movements can be translated into participatory diplomacy.

<P><B>Summary</B></P> <P>We performed an extensive immunogenomic analysis of more than 10,000 tumors comprising 33 diverse cancer types by utilizing data compiled by TCGA. Across cancer types, we identified six immune subtypes—wound healing, IFN-γ dominant, inflammatory, lymphocyte depleted, immunologically quiet, and TGF-β dominant—characterized by differences in macrophage or lymphocyte signatures, Th1:Th2 cell ratio, extent of intratumoral heterogeneity, aneuploidy, extent of neoantigen load, overall cell proliferation, expression of immunomodulatory genes, and prognosis. Specific driver mutations correlated with lower (<I>CTNNB1</I>, <I>NRAS</I>, or <I>IDH1</I>) or higher (<I>BRAF</I>, <I>TP53</I>, or <I>CASP8</I>) leukocyte levels across all cancers. Multiple control modalities of the intracellular and extracellular networks (transcription, microRNAs, copy number, and epigenetic processes) were involved in tumor-immune cell interactions, both across and within immune subtypes. Our immunogenomics pipeline to characterize these heterogeneous tumors and the resulting data are intended to serve as a resource for future targeted studies to further advance the field.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Six identified immune subtypes span cancer tissue types and molecular subtypes </LI> <LI> Immune subtypes differ by somatic aberrations, microenvironment, and survival </LI> <LI> Multiple control modalities of molecular networks affect tumor-immune interactions </LI> <LI> These analyses serve as a resource for exploring immunogenicity across cancer types </LI> </UL> </P> <P><B>Graphical Abstract</B></P> <P>[DISPLAY OMISSION]</P>
