🧂Hyponatremia is a common the ICU, but correcting it smoothly & safely can be challenging. 🧠Rapid correction risks serious complications like ODS/CPM 📈That's why I built NaPathway - a free app - to help clinicians monitor sodium correction Try it criticalcaretime.com/tools/hyponatr… 🧵

Why don't they first get them to work in bauxite mines instead of jobs that benefit from human interaction?

Oh my God, you total jackasses. EVERY country had a notable drop in life expectancy circa 2020. And you know why: COVID. Maybe you don't know that the USA had a WORSE drop in life expectancy, and started from a lower base to begin with!
Canada had a notable drop in life expectancy since 2020: "Being on the side of reality and facts is so against the narrative... they're willing to ignore an increase in all-cause mortality."
This is wild and has major implications for AI safety & control.
New paper & surprising result. LLMs transmit traits to other models via hidden signals in data. Datasets consisting only of 3-digit numbers can transmit a love for owls, or evil tendencies. 🧵

It’s wild that the goal of building a 5GW multi-million square foot data center that consumes as much electricity as New York City is to reach parity with the human brain, which does the same in 1.3 kg running on 20 W.
It is hard to get your head around how stupendously large an electricity user a 2-5 gigawatt data center represents. A 5 gigawatt data center consumes on the order of 40 million megawatt-hours of electricity per year, as much electricity as the ENTIRE STATE of Nevada or Kansas!

How is Grok both open source and its IP is being used as collateral?
The WSJ is reporting that xAI is working with Valor Equity Partners to raise an additional $12 billion in capital to buy the chips for Collosus 2. The report also claims that the Grok IP was used as collateral for the $5 billion raise in June.
If there is no exception this will kill rural health care lmao
This change will have BIG implications for international medical graduates (IMGs) doing residency in the US. No residency/fellowship salary will ever win a salary based selection, so the US medical system stands to lose thousands of H1b doctors every year from this change.
The H-1B lottery may be on its way out… replaced with a salary-based selection system. That would mean: • Low-wage roles = locked out • Early-career tech talent = sidelined • Recent grads = no path in I’m not convinced this increases American jobs. Companies won’t change…

ICU fellows/residents - I HIGHLY recommend using the ICU Trials app & its “trial of the day” feature to learn the CCM literature. You get a summary of a different CCM paper each day at a time you select. Drink coffee ☕️, read the paper📄, & take a few notes 📝 for full benefit!
Moral stupidity about a googol of shrimp aside, the innumeracy of this post is incredible. There are “only” about 10^80 atoms in the observable universe.
Okay let's clarify some things. Link below

Ghislaine Maxwell Pardon Watch starts now.
Justice demands courage. For the first time, the Department of Justice is reaching out to Ghislaine Maxwell to ask: what do you know? At @AGPamBondi’s direction, I’ve contacted her counsel. I intend to meet with her soon. No one is above the law—and no lead is off-limits.
