📍Senator Fetterman had a VFIB—the leading cause of cardiac arrest—he almost died if not for his implanted defibrillator, which can cost $34,000 to over $51,000. Days ago, he also just voted with GOP to gut health insurance tax credits for millions. Hope he has a change of heart.

RFK Jr had slashed the CDC’s program to monitor and track food-borne outbreaks back in August. Fast forward to now… deadly listeria outbreak across the U.S. has now caused 25 hospitalizations and 6 deaths across 18 states, one of the largest outbreaks. These events are linked.

INSANE INFLATION: Average ACA premiums will rise ⬆️ 30% next year. The higher premiums, along with the likely expiration of subsidies, mean millions of people will see their health insurance payments double or even triple in 2026.

⚠️TYLENOL & AUTISM—RFK Jr & Trump are wrong—the largest best study in the world in 2.5 MILLION KIDS—found no increased autism risk with acetaminophen (aka paracetamol/Tylenol). A crude analysis found only a tiny 5% risk, but once you adjust via sibling controls, the even tiny 5% risk vaporizes to 0%📉

⚠️DUMBEST ERA OF HUMANITY. Health secretary Robert F. Kennedy Jr.‘s handpicked slate of vaccine advisers voted to no longer recommend a combined shot for measles, mumps, rubella and varicella (chickenpox) for children under age 4. Some committee members said there was no evidence to support the move.

ONLY MASS VACCINATION WILL SAVE KIDS—Cases of Hepatitis B in kids and teens dropped 99% in the 1990s only after the CDC recommended universal vaccination at birth. Trump/RFK Jr now wants to reverse that, despite hard lessons from 1980s that casual vax wasn’t enough. www.statnews.com/2025/09/11/n...

📍RFK Jr. has crossed the Rubicon. The war on science isn’t looming - it’s here. I had hoped that after the darkest days of the pandemic, we could start rebuilding a stronger science world. I was wrong. So, starting today, I’m back. And I want you to join me.

New sea surface temperature record just set (red line). We are on track to set more ocean temperature records this year. Oceans can buffer a lot of temperature increase — so for ocean temps to rise this much means we could be bigger climate trouble sooner than we thought.
