The molecular biology of how Mycobacterium Tuberculosis evades the immune system so well.

Starting with this simulation of a full outer envelope of m.TB--let's explore how the deadliest & most persistent human pathogen completely hacks our immune response. #molecularbiology

This is brilliant, thanks for sharing. It does everything, sound, fun and interactive tools. Long "hmmmmm" and chin scratching

Yup! We'll add content throughout the year. The next few updates after WWDC will cover:
- Neurons 2: cytoskeleton, energy and glutamate loading
- Neurons 3: the postsynaptic neuron

and much more!

Yes!! I also love that we don't need @StateObject anymore.

Haha! thank you. That portal... I'm so happy that it's finally free. That was a lot of work and optimization!!

That's cool. Thank you

thank you :D

Thank you so much! I screenshotted this and saved it away because I believe this is the first purchase!!

Hi Christian! thank you very much. This is the version of the app I really wanted to release for the Apple Vision Pro launch Feb-2 2024. It took more than a year, but it's finally realized! I'm already working on the next version ;)

And a huge shout-out to the incredible scientists behind the bacterial cell model: @martinamaritan.bsky.social and @ludovicautin.bsky.social

😱 Thank you Gregory.

Thank you Drew!

Thank you!

Thank you Brady! :D

It features incredible scientific models, especially the beautiful Mycoplasma by @martinamaritan.bsky.social and @ludovicautin.bsky.social. Amazing guys, the folks at Apple love it.

Thank you Chris!!

From writing scientific papers years ago, to publishing an app on the App Store to inspire the next generation of biologists. What a journey...

I have more news to share.. ;)

Ahh!! My app CellWalk is a finalist in this year's Apple Design Awards.

What?! 😮 I'm beyond excited.

Thank you Apple for the honor, and a huge thank you to the incredible people there.

Hehe! thank you so much Till. See you at WWDC!!!

Me too. btw this is looking gorgeous. Are you going to be at WWDC?

Haha, it only costs me $0.60/month right now!! amazing.

I was storing huge zip archives for each point release of CellWalk on Google Drive, lol. GitHub's LFS pricing is just too much... but this is so cheap. Now I can properly version all CW data!

GitHub - milkey-mouse/git-lfs-s3-proxy: Store Git LFS files on any service with an S3 API Store Git LFS files on any service with an S3 API. Contribute to milkey-mouse/git-lfs-s3-proxy development by creating an account on GitHub.

github.com/milkey-mouse...

It took about 20 minutes to setup:
- cache all the Git LFS data (git lfs fetch --all)
- Setup a static Cloudflare Webwork LFS proxy
- Create an R2 bucket
- Create a .lfsconfig file in the repo pointing at the proxy
- finally `git lfs push --all origin`

I need to store a fair amount of data alongside my Git repository hosted on GitHub. I've been pricing things out:

GitHub LFS: $70/TB
LFS Cloudflare R2 + Webworker proxy: $15/TB
LFS Backblaze B2 + Cloudflare Webwork: $6/TB

I went with Cloudflare R2 for Git LFS and GitHub for the repo!
