A couple of useful studies illustrating diabetics should be able to tolerate hypergravity from spaceflight. Will become more and more relevant as we near commercial space flight becoming ubiquitous.

Blood Glucose Alterations and Continuous Glucose Monitoring in Centrifuge-Simulated Spaceflight

INTRODUCTION: Sympathetic stimulation is known to be associated with transient alterations of blood glucose (BG) concentration; spaceflight acceleration may be similarly associated with alterations of BG, potentially posing a risk to diabetic individuals engaging in future spaceflight activities. Despite prior studies demonstrating diabetic subjects’ tolerance to centrifuge-simulated spaceflight, data are lacking regarding blood glucose response to hypergravity. It remains unclear whether hypergravity or associated physiological response may pose a risk to diabetics. Continuous glucose monitors (CGM) offer a means of noninvasive glucose monitoring and may be useful in spaceflight and analog environments. Here, we describe the results of continuous glucose monitoring during centrifuge-simulated spaceflight.METHODS: Subjects participated in 1–5 centrifuge-simulated spaceflight profiles (maximum +4.0 Gz, +6.0 Gx, 6.1 G resultant). Data collection included heart rate, blood pressure, electrocardiogram, continuous glucose via CGM, intermittent fingerstick BG, and postrun questionnaires regarding symptoms related to hypergravity exposure.RESULTS: CGM data were collected from 26 subjects, including 4 diabetics. While diabetic subjects had significantly higher BG compared to nondiabetics, this was not associated with any difference in symptoms or tolerance. Transient hypergravity-associated CGM glucose alterations did not affect tolerance of the centrifuge experience. CGM data were found to be reliable with occasional exceptions, including four instances of false critical low glucose alarms.DISCUSSION: While further study is necessary to better characterize CGM fidelity during hypergravity and other spaceflight-related stressors, CGM may be a feasible option for spaceflight and analog settings. As in prior studies, individuals with well-controlled diabetes appear able to tolerate the accelerations anticipated for commercial spaceflight.Ong KM, Rossitto JJ, Ray K, Dufurrena QA, Blue RS.

Seeing lots of interest in Rapamycin internationally right now (dont know why, not the biggest fan).

PSA: if you are considering starting Rapamycin, and from a region or area where TB (tuberculosis) is endemic, please get tested first.

Otherwise, it's like putting gasoline on a matchstick.
This. Glad someone articulated so well.

Having lived in Bushwick pre-gentrification into its early transition for 4 years in med school (as it was the only place I could afford) its crazy how people there think they're warehouse workers now.

My apartment mates were welders, struggling artists (living 4 to a room type). Then the last 2 years the apartment next door got a full renovation and finance folk moved in with some faux country living.

Not that gentrification is bad. But lets be real about it atleast...

It’s weird because I personally have vouched for Meta Ray Bans 2x this week and gotten both people to buy them

Both times none of this slop crap was the draw

Person 1 was my brother. He wants to take more in the moment photos and videos of his baby daughter

Person 2 was my Russian neighbor. He wants to take videos on his motorcycle and show his mom back in Russia what American grocery stores are like without whipping out his phone

Both of these use cases feel very HUMAN

I am not going to say no one wants the slop but….
So we now use a real ID that needs a manual magnifying glass for verification?
This also raises an interesting dilemma of who pays for the resulting treatments.

Having experienced both on the insurance and cash forms of treatment, the capacity and willingness of people to pay for tx, especially longevity, is severely overrated.

GLP-1s are a major exception, but too often are used as a rule.

Part of me thinks, albeit reluctantly and (very) hesitantly, there are learnings for the crypto community to take from the recent growth in 'longevity' hype/adoption among the masses.

I have had a crazy amount of friends and family reach out about where they can do a Lp(a) or Dexa and then do it and come back to me asking what it means and how to improve. (which they then just do for a week and back to status quo)

A lot I think has to do with the more positive image the 'longevity' community has shaped itself to be vs the gambling of memecoins masquerading as utility.

As much as the 'next $-billion app is a toy' concept is true, it should also have some seriousness to it as well.

Wouldn’t be surprised to see many GLP-1 based economies struggle after May 21st once compounding goes away.

This includes many ‘Longevity’ companies whose main source of revenue are compounded GLP-1 meds.

HIPAA, in its current form, is the biggest barrier to keeping the US health system at par with the rest of the world.

The layers of red tape it adds are beyond imagination. And reinforced by a thriving economy of middlemen who meet at seemingly weekly health conferences with patient money.
If there was any doubt on Airbus' dominance. Especially with the A330Neo and A321 garnering such high demand.

Surprising how little activity @researchhubf has on here. A research paper mini-app would be powerful as a tool for sharing papers and providing minting capability for viewing.
Also if peer-reviews/comments can be enabled.
Found an o1-preview study that did a great job breaking down the various strengths o1 had over previous completion models. Primarily, as expected the gains are in differential development which is great to see. And management reasoning was much improved as well. Also the b&w low variability seen below is a sight to behold. Big move forward.

Next step will be to see this in clinical setting since most differentials/management falls apart after day 1 in real life. How it adapts and adjusts to that. In my own experience, it has struggles some there, but hope it continues to improve. Exciting to see.

Halfway through and the perspective on just how new learning structures are makes me more certain that we are in for a ride when it comes to learning and knowledge.

Medical education and institutions, likely alongside the Manhattan project and NASA, are likely the two biggest contributions of the American knowledge. Going forward, this will likely shift away from institutions to others of a parallel or greater size.

Playing around with some AI based learning tools as I've gotten curious about it for my son.

Realized how much of a moat (and scary) this can be if built properly with memory and customization of a student's strength and weaknesses, from kindergarten to 12th to college (if that still exists).
As mitochondrial-derived peptides (MDPs) like MOTS-c emerge as promising therapies for metabolic diseases, a critical gap remains:

How do mitochondrial DNA (mtDNA) polymorphisms impact treatment responses in diverse populations?

East Asian studies reveal variants like m.1382A>C alter MOTS-c function and diabetes risk. Yet, South Asians-who face high rates of early-onset diabetes-are rarely included in mtDNA research. Without data on their unique haplogroups (e.g., M, R), we risk inequitable access to precision therapies.
