Pytorch meets baby worms! It was a pleasure to work with @dave_matus and everyone at @ArcadiaScience to help bring this across the finish line (and on a tight deadline)!.
Want to level up your automated phenotyping with DL/ML? At @ArcadiaScience, we’ve built a classifier to categorize developmental stages of #Celegans from high-throughput bright-field time-course images #WormClassifier 🧵1/12.

This should be required reading for new grad students (not to mention their PIs).
If you go for broke you often end up broken. If you swing for home runs you often end up striking out. But if you just put the ball in play—over and over again—good things tend to happen. On how to be consistent in work, sport, creativity, and really, all of life:.

Love the hierarchical colormap! 👌🏻.
To build the core of the HLCA, we collected 14 published and unpublished datasets of healthy lung + nose from 107 individuals, with cell type annotations, and technical and demographic metadata (age, BMI, etc.). We harmonized all metadata for downstream use. (4/20)

This is a fascinating tour through the iconography of our scientific cultural heritage! 😍.
Some scientific illustrations become memes*, some turn into cultural icons. It requires a combination of originality, aesthetic, simplicity and scientific accuracy. Here are some of them 🧵.1/n. *memes in the original sense: units of cultural inheritance that replicate and evolve

Perhaps a more specific name like `!ugly-hack-added-for-specific-regulatory-reason` would have helped to prevent its widespread (mis)use for other purposes 🤔.
CSS co-designer here. !important was added for one reason only: laws in the US that require certain text to be in a given font-size. !important stops the cascade from changing it. Anything else is probably misuse, and a sign you may not understand the cascade properly.

I'm sure BA.2 is coming but this kind of data seems to be *very* noisy esp when prevalence is low, and given the abundance of blue dots mixed w red dots, I would suspect this is mostly noise.
Wastewater surveillance of Covid is relatively sparse in the US, but 62 (15%) sites have a >1000% increase in viral RNA detected in the past 15-day period.

It has been a privilege and pleasure to work with so many amazing scientists @czbiohub to help reach this milestone! All of our data is freely available to explore and download at - check it out and search for your favorite protein!.
Our paper is out today in @ScienceMagazine, I’m stoked @OpenCellCZB !. Check out CRISPR tagging + 3D live imaging + IP mass spec to map the human proteome. 👇 tweetorial from our 2021 pre-print.

With Omicron, there "are clear indications this wave will differ substantially from previous ones,” writes @ShamanJeffrey, an infectious disease modeler and epidemiologist.

Does anyone understand what’s being plotted here? Why does 2-dose drop to zero then go up?.
