Soybean Polysaccharide Improves Aging Blood Vessel Function in Mice
A soybean carbohydrate improved blood vessel function in aged mice, with gut-derived butyrate emerging as a potential link.
Four Weeks of Aerobic Training Reshapes Gut Bacteria in Middle-Aged Mice
Aerobic training changed gut microbial composition in middle-aged male mice, but whether those changes drive fitness benefits remains unclear.
Statins May Help Build Bone After Menopause Through a Stem Cell Pathway
Statin use tracked with slower bone loss after menopause, while experiments revealed how atorvastatin may support bone formation when estrogen is low.
Knee artery embolization works equally well with an antibiotic or permanent microspheres in a 12-month trial
In a 60-patient randomized trial, blocking knee blood vessels cut osteoarthritis pain by about half for a year, whether done with imipenem/cilastatin or microspheres.
Certain gut bacteria may predict how fast your body ages
A University of Hawaii study links gut microbes to the pace of biological aging, with some species tied to slower aging and others to faster aging.
Two drinks a day carry a 1-in-25 lifetime risk of alcohol-related death
A federally commissioned analysis finds that two daily drinks bring a 1 in 25 lifetime risk of alcohol-related death, with no significant overall health benefit.
Semaglutide Panic Reports Rose After Publicity, but Studies Show No Consistent Link
Panic reports rose after scrutiny of GLP-1 drugs. Adjusted comparisons and a 12-study review found no consistent link, but cannot exclude one.
Ergonomic Changes May Offer Little Relief for Work-Related Neck and Arm Pain

Two Vitamin E Forms Show Different Links to Cancer and Alzheimer's Mortality
Higher blood levels of two vitamin E forms tracked with lower mortality in older adults, but the findings do not establish supplement benefits.
Aging biology may explain why systemic sclerosis looks so different from patient to patient
A new review proposes that biological aging, not just birthdays, may help shape who gets systemic sclerosis, which organs are affected, and why comorbidities pile up.
Rapamycin Helps Injured Nerves Recover and Preserves Muscle in Mice
In mice, rapamycin improved nerve repair, preserved muscle, and supported walking recovery after injury. Human benefits remain unproven.
Disabling MTCH2 Boosts Fat Burning in Human Cells and Endurance in Mice
A protein called MTCH2 may influence fat burning and muscle endurance, but the evidence remains limited to cells and mice.
Sirolimus and paclitaxel drug-coated balloons perform similarly in coronary arteries
A meta-analysis of 8 trials and 1,043 patients finds sirolimus- and paclitaxel-coated balloons deliver similar results in coronary artery disease, with a few caveats.
Nicotinamide Riboside Improves Skin Flap Survival in Rats
NR protected skin flaps in rats and boosted cellular recycling, pointing to a possible tissue repair application—not proven benefits in humans.
Sleep Breathing Problems May Mask Leg Movements Linked to Poorer Rest
A study of 481,857 adults links nighttime limb movements to poorer sleep and health conditions—and suggests breathing problems may obscure them.
Plant Sterols Fail to Lower LDL in a Small Trial of Adults With Obesity
A small randomized trial found 2 grams of plant sterols daily did not improve LDL cholesterol or other metabolic measures versus placebo.
