The writer with a biology degree who chases the surprising result into its mechanism. Covers metabolic and autoimmune disease, longevity, and chronic illness.

Brain & Aging

Brain Gains Into Your 90s Are Probably Real. The Index Measuring Them Has a Patent Pending.

A three-year UT Dallas study tracking nearly 4,000 adults to age 94 says brain function can climb at any age. The biology is plausible. The catch is that the people measuring the gain are the same people patenting the yardstick.

Autoimmune & Inflammation

Your Thymus Quietly Stages a Lung. Researchers Just Named the Cell Playing the Part.

A new Nature Immunology study identifies an alveolar lung-like cell hiding inside the thymus, where it appears to teach the immune system not to attack your real lungs.

Autoimmune & Inflammation

A near-starvation diet shifted inflammation in gum-disease patients. The trial was tiny, and the diet came in a box.

A 28-patient feasibility trial put severe gum-disease patients on three cycles of a 750-calorie ProLon diet. Inflammation markers trended lower; clinical gum measures weren't reported. The biology question is real; the data is thin.

Drugs & FDA

Medicare's Product-Hopping Loophole Is Back On The Chopping Block. The Bigger Pharma Giveaway Isn't.

The Trump administration on Thursday proposed closing the product-hopping loophole that lets drugmakers reset Medicare's negotiation clock by tweaking inactive ingredients. It is the same fix the same administration quietly tabled in October.

The Same Mutations That Drive Blood Cancer Keep Turning Up in Alzheimer's Brains

A new Cell paper finds Alzheimer's brains are riddled with the same mutations that drive blood cancers, in the immune cells that are supposed to be protecting neurons.

Nutrition & Food

8,300 Brazilian elders, one saltshaker, and the 80 percent of sodium nobody mentions

A Frontiers in Public Health survey of 8,336 Brazilians over 60 found older men reach for the saltshaker most. Buried in the same paper: the shaker only accounts for 6 to 20 percent of total sodium. The other 70-plus percent already arrived from the factory.

Nutrition & Food

American Doctors Get About 1.2 Hours of Nutrition Training a Year. RFK Jr. Just Found the Lever.

Kennedy got eight organizations across U.S. medical training and 73 medical schools to commit to nutrition in licensing, accreditation, and a 40-hour pledge. The board exam matters; the rest is partly hedging.

Brain & Aging

Disappointment, Not Reward, Is What Breaks a Habit. Half of Older Adults Are on Drugs That Blunt Acetylcholine.

An OIST team caught the mouse brain firing acetylcholine the moment an expected reward failed to land. That surge is what lets the animal switch strategy. Close to half of community-dwelling older adults are on drugs that block the same receptors.

Drugs & FDA

Europe had this sunscreen in 1999. The FDA approved it Tuesday.

A new chemical UV filter Europe approved in 1999 just cleared the FDA after a 21-year wait, while Americans relied on ingredients the agency's own 2019 review could not call safe.

Brain & Aging

Nitrate from spinach behaves nothing like nitrate from tap water. A 27-year cohort says the brain can tell.

54,804 Danes followed for a quarter-century: less dementia from vegetable nitrate, more from drinking water. The risk signal shows up at roughly one-ninth of what the US EPA still permits.

Autoimmune & Inflammation

Fish oil rewired the T-cells in non-obese diabetic rats, and the glucose moved with them

A Brazilian team gave EPA-heavy fish oil to a non-obese diabetic rat strain for eight weeks. Glucose, insulin sensitivity, and lipids all moved in the friendlier direction. The T-cell balance shifted alongside them, and that is the part of the paper worth chewing on.

Brain & Aging

The Alzheimer's Drug That Bets the Plaques Are a Symptom

An ETH Zurich team spent nearly twenty years tracing why Alzheimer's nerve cells run out of energy, and the answer points to a protein the amyloid-clearing drugs never touched.

Investigations

A 16-Foot Fire Tornado Burned an Oil Slick With 40% Less Soot. Cleanup Crews Have Been Breathing the Same Old Smoke Since the Exxon Valdez.

A federally funded field trial used a controlled fire whirl to burn up to 95% of a crude oil pool while cutting soot by 40%, raising the question of why the standard in-situ burn, with its measured worker-lung cost, has gone unchallenged for thirty-five years.

Nutrition & Food

He Shou Wu's Hair-Loss Pitch Is Better Than I Expected. Its Liver Record Is Worse.

Researchers at Guangdong Pharmaceutical University argue Polygonum multiflorum could become the next pattern-baldness lead. The follicle biology is interesting. The case series of acute liver failure on four continents are not.

Metabolic & Weight

Lilly's triple agonist hit 30% weight loss. The glucagon bet is why.

Lilly's triple agonist hit nearly 30% weight loss at 104 weeks at ADA 2026. The glucagon bet is what makes retatrutide different from semaglutide and Mounjaro, and it's what makes the open safety signals different too.

Metabolic & Weight

Retatrutide's Triple-Receptor Triumph Came With a One-in-Five Skin-Sensation Signal Nobody Wanted to Linger On

Eli Lilly's investigational retatrutide hit bariatric-surgery-level weight loss at ADA 2026. The highest-dose arm of TRIUMPH-4 also saw 20.9% of patients report abnormal skin sensations, and a small cardiac imbalance turned up in the type-2 trial. Both got far less stage time than the headline numbe

The Herbal Steroid That Hits Pharma's Holy-Grail Kidney Target

A Shanghai lab reports a steroid from a Yunnan mountain plant, already sold over the counter to bodybuilders, suppresses the same kidney-fibrosis pathway Big Pharma keeps circling and never quite closes on.

Investigations

The Hernia FAQ That Forgets to Mention the Implant

A polished hernia FAQ walks patients through recovery time, return-to-work, and lifestyle. It skips the question with 26,153 pending lawsuits behind it, and the no-mesh option the international guideline still keeps on the table.

Metabolic & Weight

The Oral GLP-1 Race Just Got a Third Serious Contender, and Its Curve Was Still Climbing

Structure Therapeutics' once-daily oral GLP-1 aleniglipron hit 11.3 percent placebo-adjusted weight loss at 36 weeks and kept climbing in the open label. The catch: oral semaglutide and orforglipron already cleared the FDA.

Investigations

Cops shoved a doctor at the ADA meeting. The editorial they tore up has its own credibility problem.

Police escorted ADA members out of New Orleans on Friday for passing out an editorial against Trump's NIH overhaul. The shove was bad. The editorial defending the status quo has a credibility problem the press is mostly missing.

Metabolic & Weight

A gut hormone keeps showing up in the brain's reward circuit, and 600,000 veterans just gave us the biggest hint yet that it matters

A VA cohort of 606,000 diabetic veterans on GLP-1 drugs showed lower risks of new substance use disorders and large drops in overdose and drug-related death versus a peer diabetes drug. The mechanism story is where it gets interesting.

Brain & Aging

Harvard Just Mapped How a Mouse Smells, and It Quietly Rewrites What Smell Loss Means

Harvard used MERFISH to image roughly 1,100 odorant receptors across the mouse nose at once and found tidy stripes, not chaos. The clinical stakes for smell loss just got harder to wave off.

Drugs & FDA

Another Clot Problem at Abiomed: The FDA Flags an Impella Introducer, and the Pattern Keeps Growing

FDA flags Abiomed's 14Fr Low Profile Introducer Kit after a higher than expected complaint rate of clots forming on the device during prolonged Impella CP support. Three serious injuries reported, no deaths. The pattern keeps growing.

Investigations

The Crunchy Mom and the MAHA Mom Were Fighting the Same War. The Pesticide Lobby Won Anyway.

For one strange year, the EWG hiking-boots crowd and the MAHA red-hat moms were fighting the same pesticide war. Then Trump invoked the Defense Production Act on behalf of Bayer, the final MAHA report quietly stopped mentioning glyphosate, and a coalition that was actually winning got stomped by a C

The FDA Approved a Better Penile Implant. For Most Men, ED Is the Heart Warning Them First.

The FDA approved Coloplast's Titan Prime inflatable penile prosthesis on June 3, 2026. For the men whose vasculature is past saving, it is a meaningful device upgrade. For most men with new ED, the more useful conversation is what the small arteries are failing to do years before the coronaries noti

FDA's New Gene Therapy Shortcut Leans on 'Platform Knowledge.' Six Months Ago, They Revoked Sarepta's After Three Patient Deaths.

FDA's new gene therapy draft guidance invites sponsors to lean on "platform knowledge" to streamline submissions, six months after the agency revoked Sarepta's AAVrh74 platform designation following three patient deaths.
