taking my cat on her daily walk around the courtyard to the delight of the neighborhood children. you might think this is whimsy and cute, however
a grey cat eagerly walking on a brick path, wearing a bright green harness and blue leash (that has definitely also been used as a toy) grey cat with beautiful green eyes (it’s true) sitting outdoors on an apartment stoop

you ever take a picture of your cat and right side up they look silly but generally normal, but then flipped, it’s giving half-assed sock puppet
a brown cat laying on its back in a window perch the same cat but the image is flipped vertically and zoomed in on the cat’s face which is silly probably because their ear is flattened and the angle is odd a grey cat laying on its back on a mirror with a weird staring expression the same cat but the image is once again flipped horizontally and i can’t really describe it to you but the cat looks 2d, like a blob, and also very goblin-esque. again mostly in the ears

I hope that every sock you put on will be slightly rotated just enough for it to be comfortable / May your tea be too hot when you receive it, and too cold when you remember it is there / May you always step in a wet spot after putting on fresh socks / May both sides of your pillow always be warm / May your article load that tiny extra little bit so when you are about to click on a link you click an ad instead

Happy to have played a small part in this work – and hoping these data help illustrate why a strong PABS mechanism with the Pandemic Agreement is critical to align our currently fractured system into one that prioritizes global health justice.

Screenshot of AMP EID website showing a map with the scope of legislation for access and benefit-sharing. There is a mix of predominantly orange ("No ABS legislation identified") and blue ("Legislation covers genetic resources, including microorganisms, and traditional knowledge). There are also a handful of green countries ("Legislation covers genetic resources, including microorganisms") and yellow countries ("Legislation does not cover microorganisms"). There are few countries for which data were not collected (grey).

🚨 NEW: We evaluated global patterns in access and benefit-sharing (ABS) – and found a fragmented system of national policies. Only 16 countries include digital sequence information in enforceable policy – leaving lifesaving data in a gray area 🔓 tinyurl.com/3p73brw9

Why does this matter?👇
Graphical and mapped representation of countries with (A) legally-enforceable policy pertaining to genetic resource access, (B) sanctions included in legally-enforceable ABS policy, and (C) legally-enforceable policy that covers Digital Sequence Information (DSI). Bar graphs are arranged by WHO regions, with bars illustrating the percentage of countries within the region with identifiable policy for each of the subtopics. The corresponding maps, located to the right of each bar graph, demonstrate country-level status.

And, if you're not super "technical", fear not!

One of the things I'm proudest about in this paper is how we walk through the process of building and validating a knowledge graph – and determining whether it's the right tool for your question or data.

+Open code & data: github.com/cghss-data-l...
Process map depicting the steps to construct and use a custom knowledge graph from data identification to downstream machine-learning tasks. (1) Identify data requirements based on research questions, inventory data sources, and define shared data elements. (2) Develop an ontology by defining nodes as a combination of one or more shared data elements, defining edges as relationships between nodes, and using attributes to describe nodes or edges with additional detail. (3) Build the graph by extracting data from each source, labeling data elements from each source to match the ontology as a node, edge, or attribute, and ingesting data into the graph database. Note: this describes the extract–transform–load (ETL) pipeline. (4) Translate the graph into matrices for analyses, such as routine statistics or machine-learning models using knowledge graph embedding models or graph neural networks. (5) Perform analysis and modeling using the graph by converting the matrix data into parameters for population modeling, spillover prediction, epidemiological modeling, or human behavior modeling. Incorporate new, inferred knowledge into the graph if desired, refining the ontology and repeating the process as necessary. Decision tree for choosing a relational versus a graph database. (a) Decision tree based on the type of research question being asked. (b) Decision tree based on the structure of the data being used.

Some cool future directions that knowledge graphs could help with:

🔗 Integrate multiscale data + models
🚩 Detect patterns + gaps
🌎 Support hypothesis generation
🔎 Predict hidden / missing links in complex systems
🖥️ Train models for downstream analysis
Using path expansion within the graph to surface linked data. Expanding from influenza outbreaks involving Sus scrofa (wild boar) and Vulpes vulpes (red fox) within the graph.

🚨🦠 New in @bioinfoadv.bsky.social: Can we use knowledge graphs to link data across systems to make better predictions about spillover? We use bird flu to show the value of these tools in navigating complex / multi-scale systems for disease ecology 🔓😷🧪

Visualizing a knowledge graph ontology. (a) Representing subject–predicate–object (SPO) triples in a graph format. (b) The current data ecosystem; each dotted box represents a type of tabular dataset that may contain many of the individual SPO triples. (c) A domain-specific ontology to represent an outbreak. Nodes (circles) represent instances of a class, with the bolded text above or below as labels with the node classes. To the left or right of each node are the properties of that node. (d) The full ontology and schema for the zoonotic risk knowledge graph. The graph schema adheres to the ontology.
