If you are looking for cheap biotech ideas, I suggest looking to these key themes. I call them my technology of the future themes. I will even throw in some names. Just be sure to do your own DD as this is spec biotech which is risky.

New🔥 #DataScience #Bioinformatics resource: 850,000‼️ #scRNAseq cells from 226 samples across 10 cancer types draw a map of the tumor microenvironment, in particular fibroblasts.

Let’s see👇what are the main contributions of this work & what this means for #cancer #Genomics🧵 Image
But first, some background.

Cancers are (unfortunately) complex ecosystems,consisting of various types of cells.

Malignant cells represent only a fraction of the tumor. The rest is made of the tumor microenvironment/TME (fibroblasts + immune cells), with complicated dual roles. Image
Understanding the essence of this duality is key in understanding why most cancer therapies fail.

TME cells are plastic & can easily change states.

The same TME cells can either promote or suppress tumor development, depending on very subtle factors totally not well understood.

"The 21st Century Question: Emergently Engineering the Future"

Follow this 🧵 today and tomorrow for highlights from our 2022 #AppliedComplexity Network and Board of Trustees Symposium:

santafe.edu/events/annual-…

#Web3 #Cities #Polarization #EmergentEngineering #Decentralization
We start with a talk by SFI President David Krakauer:

"Would anyone care to guess why we're so GOOD at building transistors and so CRAP at designing drugs?"

"This thing [points to transistor] lives in a centralized system. This thing [points to cancer drug] lives in US."
"I'm going to pick on economics, because we like to do that at SFI. 'Ooh, look at that cover! So techy. Global, heat maps...' But here's 'Networks' [in the textbook]. THAT'S IT. Here's '#ComplexityEconomics.' NOTHING."

#GraphNeuralNetworks are way too cool to be left unexplored!

In a nutshell, GNNs are an exciting merger between graph theory (math) & #DeepLearning (coding).

Here's my detailed resource stack of best GNN theory explainers, videos & coding tutorials I used for my own learning.
1. This is a great place to start if you either: want to learn the basics, or enjoy reading about basic concepts explained in a well structured way.

It walks us through graphs in real world, what graphs & GNNs consist of, and how GNNs do prediction.

distill.pub/2021/gnn-intro/
2. Further, this next tutorial walks us through graphs & GNNs in an intuitive manner, while also going quite deep into the specific mathematical terminology of the field.

I like this one a lot because it also includes hands-on PyTorch code at every step.

This is a thread about how anyone can use publicly accessible sequence databases and free software to discover new things about #genomes, #biology, and life on earth.

#Bioinformatics #Genomics #Evolution #Science #MolecularBiology #DNA #Research #DataScience #LifeSciences Image
Genomes are absolutely loaded with complex information, most of which we still don’t understand.

Complete and near complete genome sequences are now available for many organisms.

However, decoding the information in these genomes remains a slow and difficult process. Image
A large proportion of most published genome sequences consist of DNA that is incompletely understood in terms of its evolutionary origins and functional significance. Image

$NTLA and $REGN report initial data from ph1 study of #ATTR for NTLA-2001. All patients across the two doses showed 92-94% TTR reduction at day 28.
#crispr #genomics #genetherapy #biology #biotech
At both dose levels, $NTLA-2001 was generally well tolerated. 2 patients reported transient infusion reactions, which was the only observed treatment-related adverse event.
$NTLA-2001 is an in-vivo administered #genetherapy.
It is one of the first few in-vivo #GeneTherapy being tested. Congrats to the $NTLA and $REGN teams.

A LinkedIn post by Sarah Hartley-Kane on the UK becoming the 'Silicon Valley of Global Genomics' linkedin.com/posts/sarahhk_… Image
The cost of a whole genome is probably already in the $100 mark, but not widely available: the only companies that have shown realistic goals towards the $100 genome are: MGI Tech with their DNBSEQ-T7 and T10x4 large instruments, together with @UltimaGenomics with their U100 ... Image
which is expected to be commercially available in 2023 and produces $1/Gb reads (albeit short-reads with homopolymer noise), and $ONT.L Oxford @nanopore, which is currently closing into the $2/Gb mark of Q20+ single pass reads on the PromethION flowcells Image

It’s another Thursday, and that means it’s time for another #tweetorial! Today, we want to show you how you can view RefSeq #annotations on Ensembl 🥳

#bioinf #genomics #assembly #EnsemblTraining
2/
While Ensembl gene models are annotated directly on the reference genome, #RefSeq are annotated on mRNA sequences. In other words: genome browsers will have different annotation methods, so you might be interested in comparing these annotations side-by-side 📖🤔

👂🏽You say you want to make direct comparisons of annotations between @NCBI’s RefSeq and Ensembl? Now is your time to try it out on Ensembl! 🏃🏽

Major update for small cell #lung cancer! #LCSM

With @juliensage + @FoundationATCG, our paper now on @bioRxiv:

►Genomic analysis of *3,600* pts with SCLC; largest SCLC study to date!

►Multiple interesting findings discussed in this 🧵
biorxiv.org/content/10.110…
🧵2
This study is unique in many ways:

> The #SCLC cohort studied came mostly from community sites --> representing a more typical “real-world” cohort of SCLC.
> The genomic data are tied to clinical data + outcomes.

#LCSM
🧵3
To the best of our knowledge, our study analyzes the largest number of SCLC tumors from African ancestry to date:
> n=256 AFR cases
> 7.1% of the entire cohort
#Diversity in clinical studies is critical!!

Our many-years-in-the-making EpiC Dog epigenome paper is finally out as preprint @biorxivpreprint
Close collaboration with our lab's lead bioinformatician @new__hong & MBD-seq aficionado @MethylAReum, spearheaded by our versatile PI @je_yoel @SNUnow #Epigenome #Genomics #Dog A🧵
While still in early stage format, EpiC Dog is a culmination of our efforts to annotate functional elements of dog genome enabled by chromatin states discovery and profiling super-enhancer and DNA methylome landscapes across multiple tissue types. See also BarkBase and DoGA /2
Modern dogs are champions of modern genetics. They empower us with their evolution and diversification of phenotypic traits from morphology to behavior. One reason dog genomics has become >popular compared to genomic studies of other domesticated mammals, but who's comparing? /3

Looking at a little Strategy: 🧵

I hope putting out my game plan will help other get ideas on how to do a strategy for investing to maximize returns.
1/ I am finally getting comfortable with my strategy. I have a set amount now that I am contributing to each of my portfolios for #biotech, #tech and #crypto. My plan is to use the any rallies to fade some of the companies I want get rid of that disappointed me.
2/ Then I want to use that cash to accumulate more of the companies I like. The max tax loss I can take for a year about $3,000. That would reduce my taxes and get me back about 25% or $750 in tax savings. It will work out like getting some cash back on those losers.

Yesterday, I completed my months-long quest to accurately identify all sci-fields emerging in WW other than the well-established Neuro ⬇️
For, it's been long since we noticed emerging scientific tangents that span diverse fields like: #ML, #Materials_Science, #Pharmacology, #Genomics, #Open_Hardware, etc
Awesome -- But, how does one possibly map all these frontiers without employing actual people to read and annotate dozens of hundreds of abstracts at a time?
