When Burl Ives sang “Silver and gold decorations, on every Christmas tree” in “Rudolph the Red-nosed Reindeer,” he surely didn’t know that Christmas trees actually have gold inside their needles — but that’s exactly what new research has found. A study published Aug. 28 in the journal Environmental Microbiome reports that Norway spruce trees (Picea abies) concentrate gold nanoparticles with …

Formulation of lipid nanoparticles Lipid nanoparticles were formulated following the Onpattro formulation and using a model oligonucleotide, siHPRT, as a cargo. Details regarding LNP formulation, mixing, and downstream processing are provided in the materials and methods. Briefly, a four-component lipid mixture was solubilized in ethanol to a total lipid concentration of 12.5 mM (MC3: DMG-PEG-2000: DSPC: cholesterol at a molar ratio …

Many of us associate air pollution with traffic, industry, or outdoor smog. Yet daily personal care routines can expose people to invisible risks within their own homes. Hair sprays, serums, and heat styling tools release particles so tiny they can slip deep into the lungs. New research reveals just how significant these exposures may be. Billions of tiny particles …

Broken connections between brain cells play a critical role in multiple neurodegenerative conditions, including Parkinson’s disease. Scientists have now come up with a novel way of repairing our neural wiring. A team led by University of Pisa biologist Sara De Vincentiis used mini-brains grown in a lab to test a technique they’re calling “nano-pulling”, using tiny magnetic particles controlled by …
