+
+Hello and welcome to the July issue of the Discourse Graphs newsletter! There are no summer doldrums in the discourse graph universe — only hot new plugin releases and cool tips on how to use your graph to surf(ace) knowledge.
+
+## Announcing the Obsidian plugin public release
+
+We're happy to announce that the Discourse Graphs plugin is now public on [obsidian.md](https://obsidian.md/)'s community plugin browser! This means you can now install the plugin directly from the [Obsidian community page](https://community.obsidian.md/plugins/discourse-graph) or from the community plugins browser within the Obsidian app, rather than via [BRAT](https://discoursegraphs.com/docs/obsidian/welcome/installation).
+
+## Ask the docs: what is a discourse graph?
+
+We have a new discourse graph plugin release and a growing community — but what are we all so excited about? Dive into the reason for discourse graph season with [this short explainer](https://discoursegraphs.com/docs/obsidian/fundamentals/what-is-a-discourse-graph) on the discourse graph protocol, live from our website documentation.

+
+## Dispatches from the frontier: a series on how discourse graphs are improving scientific research
+
+We've deployed discourse graph tools in labs across cell biology, biophysics, and human-computer interaction — 6+ labs including the [OASIS Lab](https://joelchan.me/lab/) at the University of Maryland, the [MATSUlab](https://sites.uw.edu/matsulab/) at the University of Washington, the [Holehouse Lab](https://www.holehouselab.com/) at Washington University School of Medicine, and the [Allen Institute for Cell Science](https://alleninstitute.org/cell-science) — as well as to individual researchers around the world. Here's what we've observed.
+
+### Better experiment planning and interpretation
+
+**Claim:** Discourse graphs surface knowledge artefacts that wouldn't otherwise exist — candidate results, unpublished measurements, lightbulb moments buried in email chains — informal evidence that never makes it into papers but shapes ongoing work.
+
+**Evidence:** A PhD biophysics researcher at McGill University used a map of questions, claims, and evidence — drawn from both literature and his own experiments — to reason about which experiments to conduct next, using their discourse graph to discover which hypotheses are well-supported and which are "baseless conspiracy theories" requiring further experiments (h/t Sean Moore).

+
+**Evidence:** A cell biology researcher at the University of Washington referred to a specific piece of evidence (not a paper, not a claim) to argue for a faster timescale in their lab's osmotic shock experiments, adapting and improving their experimental design in real time.
+
+**Evidence:** Researchers in the MatsuLab drew on informal evidence sourced from correspondence to interpret a new result, used results published internally in the lab graph to ground a new measurement, and referenced evidence and source nodes from the shared lab knowledge base created months to years prior to scope out a new project.

+
+No piece of evidence is too small — or too unpublished — to spark a lightbulb moment.
+
+**Claim:** The granularity of discourse graphs and their friendliness to incorporating informal sources of knowledge make this kind of reasoning possible.
+
+Tune in next month when we explore how our pilot users are using discourse graphs to support better synthesis of their works-in-progress!
