A Hidden Immune System May Be Sitting Inside Your Skull
For decades, the skull was treated as little more than armor, a hard shell protecting the brain from the outside world. Now, scientists studying mice have discovered specialized immune structures hidden inside the skull’s bone marrow that could force medicine to see that familiar bone very differently. The finding suggests the brain may have a…
Scientists Find 26 Genetic Clues Behind Fibromyalgia
For decades, fibromyalgia patients have faced a frustrating problem: the pain was real, but medicine had no blood test or scan that could clearly show why. Now, the largest genetic study of the condition ever conducted has uncovered 26 regions of the genome linked to fibromyalgia risk. The findings point strongly toward the nervous system…
Scientists Find a Way to Cut Cholesterol With a Single Gene Edit
For decades, people with dangerously high cholesterol have faced a familiar reality: lifelong medication, regular injections, and a constant effort to keep a major risk factor for heart disease under control. Now, scientists are testing a radically different approach that could eventually change that routine. A one-time gene-editing treatment lowered LDL cholesterol by roughly 50%…
Popular Sweetener Found in Everyday Foods Linked to Higher Risk of Heart Attacks and Strokes
A common sweetener found in products ranging from chewing gum and toothpaste to jam, yoghurt and ice cream has been linked to a higher risk of serious cardiovascular events. Xylitol is widely used as a lower-calorie alternative to sugar, and many people may consume it without giving the ingredient much thought. But new research involving…
Scientists Found Something Strange About Lithium in Nearly 400 Human Brains
There is lithium in your brain right now. You cannot see it, feel it, or measure it on a kitchen scale, but Harvard researchers spent roughly a decade searching for tiny traces of it in nearly 400 donated human brains. When they compared people who died with their memory intact against those with mild cognitive…
Scientists Found a Tiny Molecule That May Help Explain Why Our Cellular Energy Fades With Age
Of the thousands of proteins inside an aging worm, the three that fade fastest all belong to the same tiny biological assembly line. One production chain begins to fall quiet at almost the exact moment the animal’s ability to maintain its energy starts to weaken. That pattern caught the attention of Tetiana Poliezhaieva, a biologist…
Scientists May Have Finally Settled The Coffee Health Debate
For decades, coffee came with a warning. Too much caffeine could make the heart race, raise blood pressure, and potentially trigger irregular rhythms, so many people were told to cut back. Now, a growing body of research has forced scientists to reconsider that advice. The latest evidence suggests that moderate coffee drinking may be far…
Five People Whose Discoveries Saved Millions of Lives
A dying 14-year-old boy became part of a medical breakthrough that would change the lives of millions. On January 11, 1922, Leonard Thompson received an experimental injection at Toronto General Hospital while weighing just 65 pounds and fighting a disease that had almost certainly doomed him. The first attempt failed, leaving him with an abscess…
Honolulu Student Finds Fungi That Could Break Down Plastic and Sunscreen
What happens after pollution is pulled out of the ocean but remains trapped inside a filter? That question sent a Honolulu high school student from a homemade coconut-fiber experiment into a university laboratory, where researchers found fungi capable of breaking down plastic and chemical sunscreen. Vera Wang’s project produced another surprise along the way. Some…
Soft Food May Have Helped Humans Learn to Say F and V
An overbite might seem like a modern dental problem, but researchers believe it could have quietly influenced the way humans speak. A shift toward softer food may have altered human jaws over thousands of years, making sounds like “f” and “v” easier to produce and leaving a possible mark on languages still spoken today. For…
