Researchers are using an advanced brain imaging method called MEG to understand why Parkinson’s drug levodopa doesn’t work equally well for everyone. By mapping patients’ brain signals before and after taking the drug, they discovered that it sometimes activates the wrong brain regions, dampening its helpful effects. This breakthrough could pave the way for personalized …

Smoke from wildfires and structural fires doesn t just irritate lungs it actually changes your immune system. Harvard scientists found that even healthy people exposed to smoke showed signs of immune system activation, genetic changes tied to allergies, and even toxic metals inside their immune cells. ​Smoke from wildfires and structural fires doesn t just …

Researchers at UT Arlington have discovered a key enzyme, IDO1, that when blocked, helps immune cells regain their ability to properly process cholesterol—something that breaks down during inflammation. This breakthrough could offer a powerful new way to fight heart disease, diabetes, cancer, and more. By “turning off” this enzyme, the team restored cholesterol absorption in …

An AI system called iSeg is reshaping radiation oncology by automatically outlining lung tumors in 3D as they shift with each breath. Trained on scans from nine hospitals, the tool matched expert clinicians, flagged cancer zones some missed, and could speed up treatment planning while reducing deadly oversights. ​An AI system called iSeg is reshaping …

Beneath the forest floor lies an overlooked secret: many plants grow a second set of roots far deeper than expected sometimes over three feet down tapping into hidden nutrient stores and potentially locking away carbon. A new study using deep-soil data from NEON reveals that these “bimodal” rooting systems are more common than previously believed …

Researchers at ETH Zurich have developed an astonishing new material: a printable gel that’s alive. Infused with ancient cyanobacteria, this “photosynthetic living material” not only grows but also removes CO₂ from the air, twice over. The bacteria use sunlight to produce biomass and simultaneously trigger mineral formation, which locks carbon away in a stable form. …
