Scientists believe that Alzheimer’s and similar brain diseases don’t just come from bad genes—they might also rise from invisible threats we breathe in or swallow every day. Tiny particles like lead, cadmium, and arsenic sneak into our bodies through polluted water, dusty air, or cheap food, then sl
Scientists once saw mitochondria—the powerhouses inside our cells—as fixed residents with one job: producing energy. Now they know these tiny structures are more like delivery trucks zipping between cells, dropping off supplies or picking up garbage. This movement happens with help from three main h
Scientists use tiny, sponge-like materials called microporous materials for some really important jobs. Things like cleaning up pollution, delivering medicine inside your body, or even helping make chemicals more efficiently. But to make these materials work better, researchers first need to underst
First lady Melania Trump recently spoke out against claims that she ever knew Jeffrey Epstein, the financier who faced serious legal trouble before his death. In a brief statement from the White House, she called the accusations unfounded and damaging to her reputation. "The false stories connecting
Scientists have been studying how extreme temperatures impact urgent healthcare needs. Their findings suggest that while both extreme heat and cold can harm health, their effects aren't equal. The research looks at how often people end up in emergency rooms or need urgent care during these temperatu
Scientists have developed a blood test that might flag multiple cancers and other illnesses early, without breaking the bank. Instead of searching for specific disease markers, this test looks at tiny chemical tags on DNA, called methyl groups, that float around in your bloodstream. These tags act l
Scientists are starting to see a surprising link between autism, usually thought of as a childhood condition, and Alzheimer’s, a disease that shows up in old age. At first glance the two seem unrelated: one is about early brain wiring, the other about later brain decay. But new studies suggest
Scientists often ask: how do cells "know" if a surface is soft or stiff when it’s made of tiny fibers instead of a flat sheet? This question matters because the answer helps design better materials for healing wounds or growing new tissues. The study looks at two common ways to measure this stiffnes
Scientists once believed that repeating words in a sentence could help the brain remember sentence patterns. This idea came from tests where the main action word (like a verb) was repeated, making it easier to recall the sentence structure. Repeating other words in a sentence didn’t seem to help as
Scientists are using computer programs to spot hidden risks in genes that can cause the aorta, the main artery, to tear. These risky changes are called variants of uncertain significance, or VUS, because doctors don’t know if they are harmful. The new approach looks at many different features of the
