Scientists remove “zombie” cells and reverse liver damage in mice
UCLA scientists have uncovered a harmful group of immune cells that quietly builds up in aging tissues and in the livers of people with fatty liver disease. When these cells…
Scientists melt early protein clumps and shut down Alzheimer’s damage
Researchers at Tokyo Metropolitan University have turned to concepts from polymer physics to better understand a central feature of Alzheimer’s disease: the formation of tau protein fibrils. Their work revealed…
Scientists find hidden brain damage from a common pesticide
A new investigation has identified a connection between prenatal exposure to the commonly used insecticide chlorpyrifos (CPF) and measurable differences in brain structure, along with reduced motor skills, among children…
Gum disease may quietly damage the brain, scientists warn
Adults who suffer from gum disease could be more likely to show signs of injury in the brain’s white matter, according to new research published on October 22, 2025, in…
Scientists detect hidden brain damage years before MS symptoms
By the time most people begin seeking help for multiple sclerosis (MS), the disease has already been quietly injuring the brain for years. Until recently, scientists were uncertain which cells…
Reversing Alzheimer’s damage: Two cancer drugs demonstrate surprising power
Scientists at UC San Francisco and Gladstone Institutes have identified cancer drugs that promise to reverse the changes that occur in the brain during Alzheimer’s, potentially slowing or even reversing…
Popular sugar substitute linked to brain cell damage and stroke risk
From low-carb ice cream to keto protein bars to “sugar-free” soda, the decades-old sweetener erythritol is everywhere. But new University of Colorado Boulder research shows the popular sugar substitute and…
Subaru Flat-Six Engine Teardown Shows No Damage at 200,000 Miles
When it comes to Subaru engines, attention generally falls to the boxer four. And why not? From the old EJ22T to the EJ25 that powered pretty much every Subaru at…
Growing wildflowers on disused urban land can damage bee health
Wildflowers growing on land previously used for buildings and factories can accumulate lead, arsenic and other metal contaminants from the soil, which are consumed by pollinators as they feed, a…
How cells recognize and repair DNA damage
Whenever cells divide, there is a high risk of damage to the genetic material. After all, the cell has to duplicate its entire genetic material and copy billions of genetic…
