This whole essay is so damn good that it was hard to pick a pull-quote.

"This is enshittification: surpluses are first directed to users; then, once they're locked in, surpluses go to suppliers; then once they're locked in, the surplus is handed to shareholders and the platform becomes a useless pile of shit."

THREAD: Falls are a major public health problem — a top-20 cause of death in the US. Wonder what scientists are doing about that? @yunluzhu & colleagues in my lab developed powerful new tech to understand balance & evaluate therapeutics.

Thx for boosting (we’re trying to outdo that other place)!

I have spent a lot of time explaining to Russians and Ukrainians that Telegram is not a safe communications channel (I even wrote a Telegram Harm Reduction Guide) but people still use Telegram and they still tell me they do so because it's "safe" and "secure."

I hope that at the very least Telegram users in eastern Ukraine will stop.

New paper shows (as many papers before) that code that is shared will often not run. This is to be expected - few of us had training in this. But if you share code, go through checklists to prevent the most common mistakes. From the paper: https://www.nature.com/articles/s41597-022-01143-6 For some extra suggestions, see my textbook chapter on computational reproducibility: https://lakens.github.io/statistical_inferences/computationalreproducibility.html#some-points-for-improvement-in-computational-reproducibility

Today, there's a new release of https://openorganelle.janelia.org, full of features added by Davis Bennett, @avweigel and the rest of the CellMap (COSEM) team. My contribution was a new video of "fenestrae" in mouse liver hepatic epithelial cells. (1/2)

One of the hard things about immigrating to Germany is the general lack of positive feedback. I was born here, but I'm still very American, so I give positive feedback & it makes ppl uncomfortable sometimes.

This from the Max Planck Society's guide for foreign scientists:

OK, now that I've moved over to sigmoid.social, time for my first...uh...tootprint? Mastoscript? Manudon? Screw it - we wrote a paper and I want to share it with you.

Very pleased to be able to share this one: is attention all you need to solve the Schrödinger equation? https://arxiv.org/abs/2211.13672

You only need about 8 minutes a day (56 min/week) of vigorous exercise for max benefit wrt all-cause mortality, according to a new study. Most people don't understand what "vigorous" really means—~80%-ish of max HR—and won't ever get there. And there are confounds, like short time horizon, use of accelerometers, observational design, etc. Nevertheless, provocative.

We’ve mapped and analysed its circuit architecture, from sensory neurons to brain output neurons, as reconstructed from volume electron microscopy, and here is what we found. 1/

Our review with Stefan Gründer and Audrey Ortega Ramírez is out:

"Neuropeptides and DEG/ENaC ion channels: a relationship from mammals to cnidarians"

where we conclude based on structural comparisons and the #phylogeny of #neuropeptide systems that the interaction of DEG/ENaC channels with neuropeptides has diverse structural bases and many origins.

So, the European Union has set up its own Mastodon instance, EU Voice, as an official channel/platform for all its many institutions - what a great initiative https://social.network.europa.eu/about
