Researchers discovered that altering the body’s natural rhythm can help protect the brain from Alzheimer’s damage. By turning off a circadian protein in mice, they raised NAD+ levels and reduced harmful tau buildup. The findings suggest that ...
New research from Australia overturns the old idea that exercise “uses up” heartbeats. It shows that fitter people actually use fewer total heartbeats each day thanks to their lower resting heart rates, even when accounting for workouts. ...
More screen time among children and teens is linked to higher risks of heart and metabolic problems, particularly when combined with insufficient sleep. Danish researchers discovered a measurable rise in cardiometabolic risk scores and a metabolic ...
People living in socially and economically disadvantaged neighborhoods may face higher dementia risks, according to new research from Wake Forest University. Scientists found biological signs of Alzheimer’s and vascular brain disease in those from ...
Scientists discovered that a blood molecule called CtBP2 may play a major role in how we age. It helps regulate metabolism and appears to link aging across the entire body. Lower levels are tied to poor health and faster aging, while higher levels ...
Semaglutide appears to safeguard the heart even when patients lose little weight. In a massive international trial, heart attack and stroke risk dropped by 20% regardless of BMI. The benefit seems tied not just to slimming down but to deeper ...
Researchers in Japan have revealed how some gourds draw pollutants into their fruits. The secret lies in a protein that carries contaminants through the plant sap. By manipulating this protein’s structure, scientists hope to breed crops that ...
From mini-brains to spider-inspired gloves and wolf apple coatings, scientists are turning eerie-sounding experiments into real innovations that could revolutionize health and sustainability. Lab-grown brain organoids may replace animal testing, ...
By electrically stimulating macrophages, scientists at Trinity College Dublin have found a way to calm inflammation and promote faster healing. The process turns these immune cells into tissue-repairing helpers, enhancing regeneration and blood ...
Researchers used supramolecular nanoparticles to repair the brain’s vascular system and reverse Alzheimer’s in mice. Instead of carrying drugs, the nanoparticles themselves triggered natural clearance of amyloid-β proteins. This restored ...
Flatworms can rebuild themselves from just a small fragment, and now scientists know why. Their stem cells ignore nearby instructions and respond to long-distance signals from other tissues. This discovery turns old stem cell theories upside down ...
People with gum disease may have higher levels of brain white matter damage, a new study finds. Researchers observed that participants with gum disease had significantly more white matter hyperintensities, even after accounting for other risk ...
