A Daily Fiber Powder Eased Knee Arthritis Pain, and People's Grip Got Stronger Too
Six weeks of inulin, a prebiotic sold by the tub, cut knee pain 1.11 points more than placebo and added 4.62 kilograms of grip strength in a Nottingham trial, while the gut hormone GLP-1 rose alongside.
Metabolic & WeightSwitching Off MTCH2 Makes Fat Cells Burn Fuel, and an Obesity-Drug Maker Paid for the Mice
Delete MTCH2 and fat cells burn fuel faster, while precursor cells mostly stop maturing into fat cells. The dish work leaned on a cervical cancer line and mouse cells, every mouse was male, and Boehringer Ingelheim funded the key mouse study.
Metabolic & WeightMost of Finland's 'Low T' Men Reported Good Health 15 Years On, Even at Levels One Online Clinic Set Out to Treat
Finnish men in the bottom quarter for testosterone at 31 reported health and quality of life at 46 that didn't differ significantly from the top quarter, though their median level fell under the only treatment cutoff a 2022 secret-shopper study found among online platforms.
Brain & AgingMayo's Tomato Compound Against 'Zombie Cells' Was Tested in Old Mice, Not People
Tomatidine quieted aging cells in elderly mice and in human cells grown in a dish. Two of its coauthors run the company licensing tomatidine patents, and trials of other senolytic drugs in people have missed their primary endpoints.
Infectious DiseaseGhana's 1.7 Million 'Climate' Diarrhea Cases Come From a Model Where Risk Falls in the Hottest Months
Built on a UK-led official-statistics framework, the estimate compares 12 years of Ghanaian weather against a benchmark set by a rule that resolved to the 95th percentile. It does not measure climate change, and each weather exposure accounts for 5.5 percent of cases.
Drugs & FDAMice Trained to Spot THC Gave the THC Answer for CBN, the Sleep-Gummy Cannabinoid
Mice given CBN twice daily for five days grew tolerant and twitched once a receptor blocker cut it off. A Canopy Growth sleep trial of CBN found about 0.5 fewer awakenings a night and missed its main measure.
Nutrition & FoodThe 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.
Autoimmune & InflammationThe 10-Year Crohn's Prediction Model Has Never Left the Military Cohort That Built It
Antibodies against gut-bacteria flagella and Epstein-Barr virus shift years before Crohn's is diagnosed, but the models scoring an AUC of 0.90 were built and judged inside one mostly male group of U.S. service members, with no independent validation yet.
Drugs & FDAThe PTSD Magnet Therapy Touting 68 Percent Remission Hasn't Shown Its Placebo Arm
In Wave Neuroscience's earlier sham-controlled trial, veterans on a coil built to deliver no magnetic field improved about two-thirds as much as those on active stimulation. The sham results from the trial behind its FDA clearance still haven't been posted.
Brain & AgingThe Omega-3 Trial Headlined as a Brain-Health Bust Was Built to Measure Spinal Fluid
Two years of high-dose DHA reached the spinal fluid of older adults exactly as planned. The memory scores behind the "no benefit" headlines were an exploratory outcome, and 38 percent of volunteers dropped out.
Nutrition & FoodNon-Dairy Creamer Overtook Sugar as the Biggest Source of Added Calories in American Coffee
Average coffee intake barely moved between 2003 and 2018, yet its calories climbed from 43 to 60 a day, and non-dairy creamer, not sugar, drove most of the rise.
CancerChina Still Mines Chrysotile Asbestos, and Its Lung Cancer Rate Keeps Climbing
China's smoking rate and fine-particle pollution both fell, yet age-standardized lung cancer incidence rose. Zhejiang researchers argue that lung cancers from the chrysotile the country still mines are going uncounted.
Brain & AgingYour Aging Brain May Be Swapping Details for Wisdom. Nobody Has Measured the Wisdom.
Three neuroscientists argue that midlife forgetting is the brain shifting toward meaning. Older studies document the lost detail and the confident false memories that come with it. The promised wisdom has never been measured.
Brain & AgingPull One Protein Out of a Human Cancer Cell and Its Jumping Genes Wake Up Within Two Hours
Removing either of two CCR4-NOT proteins from a human colorectal cancer cell line raised transcription at about 77 percent of tracked LINE jumping genes within two hours, yet the two removals pushed jumping-gene RNA lifespans in opposite directions.
Nutrition & FoodCold Cuts and Breakfast Cereal Pulled Opposite Ways in a Giant Colon Cancer Study
In 461,682 Americans, total ultra-processed food showed no link to colorectal cancer. Inside the label, reconstituted meat products tracked with higher risk and packaged bread and cereal with lower, while a federal definition sits under White House review.
Brain & AgingThe Amino Acid That Sharpened Old Mice's Memory Made Neuron Loss Worse in Alzheimer's Mice
D-serine improved memory in old mice in a 2023 study now recirculating as news. Given to Alzheimer's model mice, the same amino acid made neuron loss worse, and the human trial behind the hype was a single dose.
Autoimmune & InflammationArthritis From Cancer Immunotherapy Comes Back With the Same T Cell Clones
Joint fluid drawn at a first flare and again at a relapse held the same expanded T cell clones, with a stronger inflammatory signature the second time. The durable immune memory these cancer drugs are sold on has a cost in the joints.
Brain & AgingClear Most of the Brain's Microglia and Alzheimer's Mice Sleep Two Hours More, Plaque Load Unchanged
In amyloid mice, plaque piled up while lost sleep held flat, and the sleep came back when most microglia were cleared. That is an awkward result for an industry selling plaque removal.
Metabolic & WeightThe Molecule Behind Fecal Odor Had the Strongest Death Link in a New Blood Aging Panel
In 18,476 people, a blood clock linked smoking and fried food to an older metabolic age and exercise and mixed grains to a younger one. The molecule most tied to death is made by gut bacteria.
Brain & AgingThe Growth Hormone Mice Release in Sleep Circles Back to Wake Them Up
In mice, growth hormone released during sleep makes the brain's alertness center more excitable and pushes the animal toward waking. The viral headline about building muscle and burning fat describes something the study never tested.
InvestigationsOven Gloves Bought From a Top Online Retailer Tested 89 Percent Asbestos
A private citizen asked two Italian mineralogists whether a cheap pair of heat-resistant gloves labeled Made in China was asbestos. The lab answered 89 percent chrysotile by weight, and the listing never said so.
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.
Nutrition & FoodAn Oil Mill's Soy Emulsifier Protected Salt-Fed Mice's Memory
Salt-fed mice got worse at remembering objects and lost interest in each other. A soy lipid blunted both, in a study a food-ingredient maker helped start and fund.
Autoimmune & InflammationYour Celiac Blood Test Can Read Normal While Your Gut Stays Damaged
The standard antibody test can read perfectly normal while a celiac patient's intestine stays inflamed. In one Oslo cohort, a nine-protein blood signal tracked the damage the antibodies kept missing.
