Dear #GeneTherapy twitter, thank you for your had work enabling cures for diseases of #Aging. What's that, you aren't working on that at all? Oh but you are, and @Nicole_Paulk and I wrote an oped to explain why: cellandgene.com/doc/why-comple…
#Aging is a set of biological mechanisms that cause all your tissues to decline in distinct ways, and in doing so lose physiological coherence. This process is the main risk factor for most US deaths (incl. #COVID19).
The systemic nature of #Aging means that old patients are usually #Comorbid, suffering from more than one disease. Our best remedy right now is often a cocktail of drugs, whose side effects interfere with each other and further strain other organs.
#GeneTherapy gives us the #Precision to treat distinct dysfunctions in each tissue, treating each disease without aggravating others. This will finally enable a paradigm of treating, not managing, the ailments of old age.
So thank you to the whole #GeneTherapy field for developing the technology that enables #GeneTherapyForAging.
To people at companies like @SangamoTx & @SanofiGenzyme, working on complex diseases like #Parkinsons, and to early #Aging efforts @eskamoah @geochurch @celinehalioua

I'm struggling to wrap my head around the new Weissman lab myHSC depletion paper:
The first authors don't seem to be on twitter but hoping I can crowdsource a fun discussion. @dbgoodman @ImmunoFever @Jeff_Mold @Satpathology @CalebLareau...nature.com/articles/s4158…
The premise of the paper is that immune function declines with age in part because a haematopoetic stem cell (HSC) population skewed towards myeloid lineage increases in prevalence, and that targeting this population with antibodies can restore function. Cool idea!
❓1⃣: How well defined are myHSCs?
Here myHSC seems to be defined as CD150 high, based mainly on Beerman 2010 .
But looking at Figure 3, CD150 expression is a continuous distribution. Is this a clear cell population with somewhat understood behavior? pnas.org/doi/full/10.10…

If you want to build a career in biotech, should you get a PhD after college or join a company directly (as a Research Associate/RA, usually)?
There's no single answer, but I have the conversation often enough that I thought I'd share some pros/cons... (1/n)
First, see this thread about different types of biopharma companies. For reasons I'll get into, I think early stage (probably founder led) biotech is your best bet unless you still want to do PhD later.
(PS if you want to be a professor, it's 💯 PhD) 2/n
PhD will give you more options.
Some companies (incl. @GordianBio) will help you grow from RA to Scientist role (and beyond). But many, esp larger, companies have a glass ceiling if you don't have a PhD. Even if you pick one w/o glass ceiling, you'll be worse off it if fails. 3/n

All these points resonate, for early stage biotech at least. @erlichya touches on this, but I think worth separating "industry" into different clusters that will feel quite different to someone coming from academia (still oversimplified, of course):
Pharma (eg Pfizer) vs biotech:
You wear fewer hats, see less of the company but company as a whole spans wider range of expertise, fewer changes in direction, often higher income but no chance of getting rich. Both have job insecurity: pharma doesn't go die but programs do.
Clinical vs R&D stage biotech:
Clinical may still have R&D but it's no longer the biggest driver of success vs failure. Assay validation/rigor > assay development/invention. Clinical can feel more like pharma, but with more urgency/stakes: one program = life or death of co.

#SciTwitter After a lot of research and asking around, I'm making the lab equipment recommendations 🧵 I wish I'd had 2 months ago. RT/share with a #newPI or startup 🔬⚗️🛒
Note, much of the equipment hasn't arrived yet, will add comments after actual use.
-80 #freezer
Two clear winners: PHC (@panasonic) and Stirling Ultracold. Both low energy, quiet, reliable. We went with PHC because I know those to last many years, and slightly cheaper.
Thanks @MarcoJost_ @letUbeU @aryelipman #MBCBiolabs
-20 #freezer
Less clear, many viable options. We ended up getting a split of PHC MDF -30 (recommended as quieter) and much cheaper Corepoint Scientific/@VWR, will see which we prefer. Thermo hasn't failed #MBCbiolabs, but $$$ and several people said poor customer support.

Something is changing about how scientific research is funded.

@Jasonmmast @endpts covers a growing set of science funding experiments: endpts.com/inside-the-mul…
These include high-throughput grants (e.g. #Fast, #Impetus), new institutes (@ArcadiaScience, @AltosLabs, @arcinstitute... I guess A is for new beginnings?), and new structures like 'nonprofit startups' (@Convergent_FROs) & @newscienceorg.
As with all experiments, I expect that some of these will disappear and that others will be a central part of science in ten years.
But them happening at all is enough to renew a conversation about how science is funded and conducted.

💸 98 Longevity Impetus Grants were awarded in 2021, thanks to generous donations from @juanbenet @jamesfickel @VitalikButerin @JedMcCaleb @KarlPfleger @FEhrsam and 1 anonymous donor.
I'll summarize outcomes in this thread, awardees listed in prior one:
🦸🏽 While I've been doing most of the tweeting, the Longevity Apprentices @LNuzhna @kush__sharma @edmarferreira & Tara Mei are the real heroes for running the operations.
This has been a great Apprenticeship project, merging action and exposure to research
martinborchjensen.com/apprenticeship
🚅 The review + awards process was fairly smooth, thanks in part to @kush__sharma's custom reviewer UI. Several reviewers told us unprompted that it was their best review experience ever; the UI took 2 wks to make, so there's low hanging fruit for other agencies in that area.
