The CDC updated its vaccine page to claim "vaccines do not cause autism" is "not evidence-based" and studies were "ignored." This is an outrage. Decades of research have found no link. This isn't science, it's RFK Jr. using the CDC as propaganda. Children will die because of this.

A question for network scientists: what are some significant events/discoveries/papers in the history of network science? I'm trying to put together a bird's eye view of network science history for my class!

Puking is a predator defence trait expressed by larvae of pine sawflies, and the grand question is who contributes to collective defence when it’s cheaper to the individual to freeride on others’ defense effort. Tantalizingly, females in this species contribute more.

New preprint: with increasing resistance to ceftriaxone, the last recommended antibiotic for gonorrhea, we urgently need new drugs. Two--zoliflodacin & gepotdiacin--are up for approval by the FDA in Dec. Here we show a point mutation can result in cross-resistance. www.biorxiv.org/content/10.1...

I think this will be cool satellite! A brand new higher-order network dataset and networks science friends...going to be hyperedgy 👀
dear hypergraph enthusiasts,
I am thinking about applying to do a satellite hackathon at @netsciconf.bsky.social focusing on our Bluesky starter pack dataset! if you work with higher-order networks and would be interested in giving a brief methods talk at this hypothetical session, please reach out!

I loved working with this team, and I hope you'll use our dataset!! Check out the talk that @diesagar.bsky.social will be giving at the Software and Data for Supporting Network Science Workshop @netscience.bsky.social. It's going to be lit!!!

Flexible Spending Accounts are hot garbage and anyone who suggests them as a solution to anything should be slapped immediately.
"Guess how much care you need! Hope you got it right! The insurance company everything left at the end of the year!" Just raking in profit, as if they needed more.

Anyone have any suggestions for a free online course (YouTube, etc.) that (1) introduces Python at an intro level and (2) is not too time intensive (<20hrs)? (Especially for students going from R -> Python!) The end goal would to do network analysis with NetworkX and understand what is going on.

This was fun to write with @lhd.bsky.social and I've never written a piece combining ontology ("what are groups?") and software ("how can we operationalize these abstract concepts?")! We hope you'll check it out!
We wrote a little something! @nwlandry.bsky.social and I talk about how new software to study networks with groups (like @xgi.bsky.social !) can help interdisciplinary collaborations tackle old questions from social ontology and the science of groups.

I thought of a funny(?) joke that won't be relevant until the fall 2025 #Python release. I'm gonna post it now because I bet we'll see a lot of this joke then and i want to make sure I get it in first...
