🚨 8.4 MILLION people study in South Korea found significantly higher rates of TURBO CANCER among COVID-vaccinated individuals compared to unvaccinated individuals. Published in Biomarker Research, the study examined cancer diagnoses within one year of COVID vaccination. Researchers reported the following increases in relative cancer hazard: • Prostate cancer: +68.7% • Lung cancer: +53.3% • Thyroid cancer: +35.1% • Stomach cancer: +33.5% • Colorectal cancer: +28.3% • Breast cancer: +19.7% The researchers also found differences depending on the type of COVID vaccine administered, with mRNA vaccines associated with increased risks of thyroid, colorectal, lung and breast cancers.

There are more than a dozen studies comparing vaccinated to totally unvaccinated populations. Children who have never been vaccinated have significantly lower incidence of multiple acute and chronic diseases, including asthma, nut allergies, ADHD, eczema, cancer, ear infections, autism, etc. The @CDCgov should conduct its own review of this data, but won't. One is left to wonder why. @NicHulscher @P_McCulloughMD @BrianHookerPhD @SecKennedy

What are the many positive differences in health outcomes in children who aren't provided basic primary prevention like vaccines and prophylactic vitamin K and eye drops?

Boom also had a board meeting where the board told me to shut the company down. XB-1 hadn’t broken the sound barrier yet. The team deployed in the Mojave desert was exhausted from months of fighting tough technical issues. We had only a few weeks of cash left and no one saw a path forward. My audit committee chair quit without notice. At first, I was pissed. I told her she would make it look as if we had an accounting scandal when in fact we were squeaky clean. But eventually, I realized the attrition was a gift. Hard times are a crucible for the truly committed. Boom had acquired some fair-weather friends, on the board and inside the company, and when times got tough, they all ran for the hills. It was some of Boomā€˜s darkest days, but we also found out who was really with us. I’m grateful for the team, the board members, and the investors that doubled down with us when the chips were down. We wouldn’t be here without you. Supersonic flight would still be illegal. Alex Gerko, @paulg , @sama, @reidhoffman , Michael Moritz, @jgebbia, @davidcowan, @avichal, @collison, @ycombinator saved Boom and gave the world a real shot at supersonic passenger flight.
A Tesla executive once described a board meeting where Elon was told by three separate advisors that Tesla would not survive the next quarter. The money was gone. The Model 3 production line was failing. Media was running daily stories about Tesla's imminent bankruptcy. One board member suggested exploring acquisition offers. Another suggested a controlled bankruptcy that would protect the brand. The third suggested Elon step down as CEO and let someone "more experienced" navigate the crisis. Elon listened to all three without interrupting. Then he stood up, walked to the whiteboard, and started drawing the production line changes he wanted implemented by Friday. Not next month. Friday. The executive said nobody in the room spoke. Not because they agreed with him. Because they realized he hadn't heard a word of what they said. Not because he was ignoring them. Because the possibility of Tesla dying simply did not exist in his reality. It wasn't optimism. It was something closer to a glitch in how his brain processes outcomes. Failure was not a category his mind could file anything under. Tesla survived that quarter. And the quarter after. And the one after that.

I’ve wanted to go to the Moon since I was a kid and now, we’re making it happen! Incredibly proud of the team at Impulse. Lots of engineering ahead, and I can’t wait!
Humanity’s next giant leap isn't getting to the Moon. It's staying. A permanent lunar presence will take more than astronauts and rockets. It will take power, communications, rovers, habitats, and the infrastructure to make life on another world possible. With two missions awarded under @NASA's Moon Base program, we're building the end-to-end transportation system to connect Earth orbit to the lunar surface. Helios will provide rapid, long-distance transportation. Mira will precisely host and deploy payloads. And our lunar lander will deliver essential cargo to the surface. Together, our fleet will helpĀ turn the Moon from a place we visit into a place we stay. Every new world begins with a way to reach it.

Hey doctors! How many of your patients are saying this exact same thing right now? – at Tennessee, USA

In my experience AI is a LOT better than our current doctor. And I'm too old and grumpy and crippled-up to get a new doctor. I would LOVE to have an AI that could prescribe my pills. AI doesn't have to be perfect. It just has to be better than modern, we-don't-try-very-hard people. That's not a high bar.

Turbo cancer. Caused by vaccines. It is real. I have seen it first hand.
ā€œSHE DIED BEFORE SEEING HER FIRST ONCOLOGIST.ā€ Carrie Sakamoto, the Allison Inquiry's first vaccine-injured witness, shares the heartbreaking story of her mother, who developed cancer following a Covid-19 booster and died before she could see her first oncologist. Carrie also speaks about her own ongoing struggles after receiving AstraZeneca and Pfizer doses, including serious neurological symptoms, Bell's palsy, difficulty swallowing, and 17 days in hospital. Five years later, she continues to live with memory loss and vertigo. She describes the financial burden of trying to access treatment, explaining that the partial compensation she received does not cover the cost of any of her treatments. Her testimony brings together two deeply personal stories: the loss of her mother and the ongoing challenges of living with an injury while struggling to afford care.

Why are people dogmatic about trying to lower their cholesterol? Do they want to die sooner? ~2.5x more likely to die if you lower your cholesterol.

At dim sum lunch with a number of people. We started talking about how the carnivore diet helped us, and how we I lost 60 lbs in six months, and my wife lost 2-3 lbs every week and how we kept it off now for 3 years. One man in his 30's already had severe back and knee pain that he had to go on crutches for a while. His doctor told him that his back can't take it and he has to lose some weight. The other men at the table also had to lose weight and they agree that they should stop eating or at least cut back on carbs after hearing our stories. They stopped eating the carb heavy dishes at the table. The man with the back pain then ordered dessert and ate it. 😱 The man that needed to cut back the most was the man that could not control his carb addiction. Carb addiction is real folks.

He's right, and I've been warning doctors about this. If you don't get your sh*t together, there will be one hourly-wage doctor supervising an LLM that's treating a thousand patients, and a lot of doctors looking for work. The AI got 83.2% right on 304 New England Journal of Medicine cases. Generalist doctors got 36.1% right. science.org/doi/10.1126/scie… – at Tennessee, USA
Microsoft's diagnostic AI solved 83% of 304 complex New England Journal of Medicine cases. Generalist physicians with reference materials solved 36%. We need to get this technology into clinics safely and fast. We need to stop making people wait for the right answers.

I'm a former cardiovascular pathophysiologist. Read carefully: The pharmacological lowering of the expression of any of the phospholipids is a fool's errand, is contraindicated, and is criminally incompetent and misanthropic (despite the consensus view of any medical council).

Update #2 (after meeting with the @bot @SpaceXSI engineering team): - Team is great. They care a ton. They owned it. - They admitted that it was almost entirely from pulling Opus 5.5 out. Which is now back as of this AM. - Learned a little bit about the context-compaction process with Grok 4.7-summarize which is not a public model. Plays a role in routing config and the summary we get back. - Grok 5.0 should be insane next level (just as an aside point) - I am somewhat surmising on why stuff went so poorly over the weekend but a lot of it has to do with not just pulling Opus 5.5 out but when they did that a known problem (and was on cursor as well) showed up which is when you switch the model mid task (which would’ve happened by removing our 5.5) it cannot remember the context and even of what it can gather its truncated (likely do to 4.7-summarize compacting). So in our case what likely happened was we had a lot of stuff mid flight that was likely pulling on opus 5.5 heavy, then it got pulled, routed to different model, forgot the context, and turned incredibly dumb. We laughed when I showed them a project that was mid flight in a doc. The first half of the doc was intelligently designed, formatted, etc. and the second half of the doc was a wall of seemingly incoherent, non formatted text. Again, I’m surmising but I think it was dumber model with all context removed - I won’t say much here but Elons comment on it being ā€œunsustainably high relative to revenueā€ was a much larger chess move. Won’t say much past that. Not my place. But he’s definitely playing a much larger chess match than just ā€œGrok bot isn’t sustainableā€. - The problems we all experienced should be fixed and I do not think they want to go back to what they experienced over the weekend with the hit it took. - They are very much focused on the enterprise use case for grok bot in the future All in all, how’s this impact my decision making moving forward with the enterprise contract we have: - Honestly still weighing the decision vs just using team plan. Working through some terms - the reason to move forward is pretty simple. Unlimited users (so not paying per seat but for usage), access to forward deployed team and engineers for support and circumstances like I just experienced, very granular governing and guardrails for the org. That’s it Impressed with the team overall and I think the main benefit to staying vs moving to open source (for a company like mine vs being a solo/small company) is trusting their ability to ship and keep building plus keep it maintained. Shoutout to @ASankarraman for jumping in to help and to the @SpaceXSI, @bot, and @elonmusk teams
We were slated to sign for a mid 6-figure contract this week with @SpaceXSI to roll out @bot across the org. That fell apart over the last few days with the severe drop in quality with no control over models and the comments on it being unsustainable. Had a killer pilot with them but it died at the finish line. Unlike the rest of X I’m not going to sit here and complain but it gave me a bit more insight into enterprise buyers (of which we sell to as well) There is this massive uptick in what I’ll call buyer commitment reluctance. Signing an annual or multi-year in a world where things are moving so fast is becoming brutally difficult to do. Do I think @elonmusk will dial it in extremely fast? Of course. He’s the GOAT. But for 3 days, when the quality became so undependable it forced us to go look at how we might be able to solve this in another way that doesn’t require the commitment of significant spend with the combination of no control over what models get used and on what. Makes me consider how we might be positioning ourselves in our own sales process. Still a huge fan. Will still use it with some key leaders on the team but the risk is just too high.

Thanks for finding this figure Mark @bulkbiker. This study was completed by the world's most ardent medical promoter of veganism, Dr Neal Barnard. A diagnosis of Type 2 diabetes includes an HbA1c of less than 6.5%. At the end of this trial, the HbA1c was still greater than 7.5% in the vegan group and also in the controls who, incidentally, were following the diet prescribed by the American Diabetes Association - a diet which then and now continues to make no impact on diabetes reversal/remission/cure. So both groups in this trial were eating diets they were promised are the gold standards for diabetes control and all would end up developing the complications of diabetes in their later lives.
Low fat vegan for T2 against SAD Small improvement to start then worsening over time. Neal Barnard (vegan doc) own study. Nowhere close to remission. Your "research" is either crap or blind.

🚨🚨 THE DEMOCRACY FILES / THE INSURRECTION PLAYBOOK, SPECIAL EDITION: ON CROSSING THE RUBICON 🚨 Many people on š• are calling for elections to not to be certified, or for Trump to not to seat the new Congress on January 3rd. In a sense, attributing 2026 results to cheating is too narrow of a way to look at a much larger and a much worse problem. The problem isn't that machines decided to flip 15% of Republican votes and stole the 2026 midterms from us. The problem is that our elections are untransparent, monopolized by mysterious NGOs, and set up institutionally such that they are impossible to challenge or audit honestly. I wrote a book, UNELECTED. It lays out the whole NGO Administrative Complex and how they have monopolized virtually every facet of our ordinary society and perform functions through, above, and despite Congress. This is what they do. They cut off every single plausible path to their own reform. The last two chapters explain my remedy, but I do not believe these chapters are easily approached without reading the other 300+ pages first. And I've had fans compare it to "A Brief History of Time" in complexity ... while I wouldn't go that far, it is an enormous problem with an enormous network that developed over an enormous amount of time. The good news is that our anger at finding out about this, and our lashing out at all this is the epistemic bubble popping. Regimes don't last long after that. The bad news is - to borrow a phrase my friend uses - there are many ways to lose, and few ways to preserve our Republic. I'm not here to tell you that President Trump shouldn't use the 2026 elections to force a showdown. I'm here to tell you what happens if he does. If he goes down this route, he better treat it like crossing the Rubicon. Pray for peace and wisdom for the administration as they deal with the many difficult decisions ahead. Watch the video with an open mind and heart.
