Continuing our network visualization series.
Research has long focused on a few related disordersโ€”but genetics now reveals links across nearly all diseases. The HDN, developed by @barabasi.bsky.social maps genetic connections between disorders, offering a genome-wide roadmap for future discoveries.

* Decoupling geographical constraints from human mobility *

๐ŸŒ๐Ÿšถ How much of our movement is about human choice and how much is constrained by geography and the spatial layout of locations?

Our paper (out in Nature Human Behavior) gives you a practical way to tell:

Cory Glover My research applies network science to uncover the organizing principles behind the complex systems that shape our world. From transportation and social media to nanomaterials and Broadwayโ€ฆ

I've gotten some new followers so I thought I'd introduce myself.

Iโ€™m a 5th-year PhD candidate in network science with an applied math background, working with @barabasi.bsky.social. I study complex systems and love being the "math guy" on interdisciplinary problems. Check out my site or say hi!

Hack of federal court filing system exploited security flaws known since 2020 The intrusion into the federal judiciaryโ€™s case filing system was like โ€œtaking candy from a baby,โ€ said one person with knowledge of the hack.

The PACER hack is getting worse and worse: "investigators suspect that Russian hackers played a role [โ€ฆ] and have grown bolder about how much data they steal over time. That includes pilfering source code [โ€ฆ] and vacuuming up sealed case data." www.politico.com/news/2025/08...

OMFG.

One of the surveys being cut by DOGE is the BJSโ€™s Survey of Inmates in Jails.

Jails are simultaneously HUGELY important and preposterously UNDER-STUDIED.

And this will just make it so so SO much harder to study them.

Arguably, jails are more consequential than prisons:
