The Mediterranean Diet's Mitochondrial 'Boost' Comes From One Blood Draw in 49 Heart Patients
Older heart-rhythm patients who ate closest to the Mediterranean pattern carried more humanin and SHMOOSE, but nobody's diet was changed and both gaps landed at p = 0.046.
Drugs & FDABlood Pressure Fell Further on the Switched-Off Ear Clip Than on the Real Device
Daytime systolic pressure fell 5.50 points on a zero-current fake ear clip and 3.15 on the active device. Queen Mary's headline said the stimulation "shows potential."
Nutrition & FoodMicroplastics Make Tissue-Damaging Radicals in Water, No Sunlight Required
With no light, heat or catalyst, water turned the surfaces of six common microplastics into a source of hydroxyl radicals in lab tests, and the plastics that made the most radicals ruptured the most red blood cells.
Metabolic & WeightThe Calf Ache Medicine Shrugs Off Can Turn Deadlier Than Some Cancers
Advanced peripheral arterial disease kills 30 to 50 percent of patients within five years, a worse record than some cancers, yet most symptomatic patients in one large U.S. study never got the basic drugs they qualified for.
CancerNature Medicine Retracted the Lung Cancer Trial That Made Infusion Timing Look Like a Free Win
Its protocol was dated January 2022 but cited papers from 2024, and the editors called its survival curve smoother than a phase 3 trial should produce. A top journal published it anyway. The early-infusion claim is gone, but the body-clock question is still open.
Autoimmune & InflammationNovo Nordisk Paid to Count the Inflamed Heart Failure Patients Its Antibody Is Chasing
Three big studies putting heart failure inflammation anywhere from 38% to more than half were funded by Novo Nordisk, whose IL-6 antibody missed its first outcomes trial in July. Their predictor tables point at fat, smoking and kidneys.
Drugs & FDAA Heart-Failure Implant Won by 40 Points on a Questionnaire Filled Out by Patients Who Knew Which Arm They Were In
Patients given Berlin Heals' microcurrent implant reported quality-of-life gains eight times the control arm's in an open-label trial. The blood marker and exercise test that could have backed them up showed no significant difference, and the company paid for the study.
InvestigationsIn Cancer Alley, the Most Polluted Air Came With More Than Four Times the Odds of a Newborn Heart Defect
Among Louisiana mothers without private insurance, the heaviest modeled industrial air toxics tracked with 4.29 times the odds of a baby born with a heart defect. The scientist who led the work says Tulane gagged her pollution research.
Nutrition & FoodEven the Vitamin C Made the List: 112,000 People and Eight Everyday Preservatives Tied to High Blood Pressure
Ascorbic acid, citric acid, sodium nitrite: three of eight common food preservatives that a 112,000-person French cohort has now linked to higher blood pressure, with the researchers asking the FDA and EFSA to re-check them.
Metabolic & WeightWhat Fluoride Does Once It Gets Past the Teeth
As Washington fights over whether to keep fluoridating tap water, the sharpest evidence on childhood fluoride and cardiovascular risk comes from places where the dose dwarfs anything out of a U.S. tap. The whole argument is about how much.
Metabolic & WeightFluoride and Kids' Hearts: The Reassuring Study Tested Water Below What US Taps Are Told to Add
Researchers measured fluoride and heart risk in 161 Iranian children, and the main analysis found no significant link. But they drank water below the level US taps are told to add, and a different adjustment flipped the numbers.
Brain & AgingEurope's Wildfire Smoke Has a Second Blast Radius: Stopped Hearts and Mood-Disorder ER Visits Far From the Flames
When California's wildfire PM2.5 climbed, depression ED visits rose 15 percent and mood-disorder visits 29 percent up to a week later, and per microgram that smoke was tied to larger health effects than ordinary city smog.
Metabolic & WeightSleep apnea's heart damage may run through the gut, not the airway
Researchers at UCSD report that knocking out a single bile-acid receptor abolishes the arterial plaque sleep-apnea conditions would otherwise drive in mice. The mechanism fits the CPAP era's underwhelming trial record better than the airway story ever did.
Drugs & FDAThe 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
