It is time to introduce the hashtag #AvalonH90. This groundbreaking device leverages quantum effects to directly map effective electrical current vectors inside the heart. It completely eliminates the need for radiation, invasive procedures, contrast agents, or claustrophobic scanning tubes. With just a three-minute scan, it delivers a comprehensive analysis of cardiac electrical activity—accurately detecting critical abnormalities and life-threatening conditions like myocardial infarction and unstable angina

Yesterday’s Starship launch

The incomplete Raptor relights on Super Heavy during the final minutes of descent are most likely caused by something that is literally sitting on the surface of the vehicle. Previous boosters with Raptor 2 engines carried substantial heat protection that shielded both the engines and the upper face of the thrust plate that mounts them. Raptor 3 engines no longer need that individual protection, but the plate itself still does. During high-speed atmospheric descent the unprotected surface receives aerodynamic heating and mechanical load; that energy conducts straight into the propellant transfer lines and the tank structure. The result is intensified local boiling, two-phase flow or elevated vapor content in the feed system, and the consequent failure of multiple engines to light reliably for the landing burn. I spent more than a decade at RKK Energia and held the world records for the lowest liquid-helium evaporation rates in cryostats for decades. The thermal path and boil-off dynamics described above are exactly the class of problems I worked on. Happy to discuss the details if useful. @SpaceX

The most powerful moving object ever created by humans

@hemo_shk You are entirely correct, and thank you for emphasizing that distinction. The previous evaluation did not properly account for the specific location shown in the image.

@bakharev_a Good suggestion,But the lesion is on the bulbar conjunctiva and not in the cornea.

A striking image with an unforgettable finding . What’s your diagnosis?

@TrackYourHeart The most likely diagnosis is a thoracic aortic aneurysm (specifically involving the aortic arch and descending thoracic aorta), which is heavily calcified.

An 87 y/o woman presents to the ER with chest pain following a fall. What is the most likely diagnosis based on this chest X-ray? (Case contributed by Craig Hacking.)

Q fever: Coxiella burnetii is a small, Gram-negative bacterium that acts as an obligate intracellular pathogen. It primarily infects livestock (such as sheep, goats, and cattle) and causes Q fever in humans, typically through the inhalation of contaminated dust or reproductive fluids from infected animals.

Coxiella burnetii is best known as the causative organism of: A. Cat scratch disease B. Q fever C. Lyme disease D. Tularemia

@elonmusk I bet that EDS audience hates this picture

Latest heat shield design looks great!

@cb_doge The time has come to launch the first 60 Starlink V3 satellites into orbit!

Time-lapse of today’s Starship flight, from liftoff to splashdown, in just 150 seconds. 🚀

@elonmusk Flight 13 was a huge success. The excellent new booster has already gone through every phase SpaceX normally runs. Finishing the tune for a clean catch isn’t a big deal — the final phase will be conquered the same way they always do it.

Starship is intact, floating in the ocean and transmitting telemetry!

@TrackYourHeart It's the Dressler syndrome an immune-mediated pericarditis that characteristically develops 2 to 6 weeks after an acute myocardial infarction.

A patient develops pleuritic chest pain 3 weeks after an acute myocardial infarction. What is the most likely diagnosis? A. Reinfarction B. Dressler syndrome C. Pulmonary embolism D. Stable angina

@TrackYourHeart WPW

Name the wave indicated by the arrow and the pattern or syndrome associated with it.

@SpaceX @SpaceX @elonmusk SECURITY ALERT SpaceX needs to be on high alert. Short sellers are already sitting on 32% of the float — roughly $23–25 billion in positions. That’s not noise. That’s a massive, concentrated bet against you. Security must be airtight. No room for error.

Lieu, why do people actually join the army? What the hell for, to enjoy a safe, comfortable life? Is the military just a game to you? Did you join an army funded by taxpayers just to hide in safety while expecting the enemy to die by the millions? Are you talking about a virtual army or a real one that faces actual combat and the risk of death? This isn't a game.

@HillaryMilfy7r @elonmusk I din't see it yet

@bakharev_a @elonmusk You'll see this happen before long Trust me

Starship static fire

Loss of the Right Heart Border (Silhouette Sign): The right heart border is formed by the right atrium and sits anatomically adjacent to the medial segment of the right middle lobe (RML). When the RML is consolidated, the radiographic contrast between the heart and lung tissue disappears. This is a classic positive silhouette sign indicating RML pathology. Intact Hemidiaphragm: The right hemidiaphragm remains sharply outlined. This rules out right lower lobe involvement, as a lower lobe opacity would obscure the diaphragm contour instead. Clinical Correlation: The patient's acute presentation of fever, dyspnea, and a productive cough strongly points toward an infectious process (pneumonia) rather than a simple collapse (atelectasis).

A 40 y/o woman with no hx of smoking presents with fever, dyspnea, and a productive cough. Based on the clinical history and the CXR findings, what is the most likely diagnosis? A. Right middle lobe atelectasis B. Right middle lobe pneumonia C. Right upper lobe atelectasis D. Right upper lobe pneumonia

@elonmusk Listen, @CoreyJMahler, please don't conflate things that don't go together! Many of the "boomers" I know support the Republican Party and Trump's political agenda. Conflating these two categories is also an insult to the "boomers" themselves.

Arguing with NPCs is pointless

I asked Grog today: "What would happen if just 20 million of Elon Musk's 240 million followers bought at least 50 shares of SPCX each within a span of 10 to 30 minutes today?" Answer: The stock price of SPCX (SpaceX) would spike extremely hard, trigger repeated trading pauses, and create one of the most disorderly short-term moves in modern equity market history. The scale of the buying relative to available supply makes this far more extreme than typical meme-stock or retail-driven events.

@elonmusk A battle between "America First" and "America Last" principles is playing out in SPCX trading. Share prices are jumping all over my monitor screen! @SpaceX

@BillAckman Where is Mitch McConnell? What really happened to Lindsey Graham? How did the GOP drop two active Senate seats in just a month? The public deserves the truth, not silence. We need a thorough, public investigation by Todd Blanche’s team immediately. #SenateChaos #GOP #BreakingNews
