For decades, medical textbooks told us that once childhood was over, the brain stopped producing new neurons. But cutting-edge research is now rewriting that story. Scientists at Karolinska Institutet have discovered strong evidence that adult neurogenesis—the birth of new brain cells—does happen, particularly in the hippocampus, the part of the brain that controls memory and […]

For decades, heart attacks have been explained through the lens of cholesterol, hypertension, diabetes, smoking, and lifestyle habits. But new research from Finland and the UK suggests there may be another player in the story—bacterial infections. This groundbreaking study proposes that dormant bacterial biofilms inside arterial plaques can become active after viral infections or stress, […]

When most people think of a stroke, they imagine sudden paralysis, slurred speech, or intense pain. But the truth is, not all strokes come with dramatic warning signs. Some are “silent,” yet they quietly cause long-term brain damage and raise the risk of future, more severe strokes. For doctors and patients alike, recognizing these less […]

Oral contraceptives have long been known for family planning and reproductive health. But recent research has revealed a surprising benefit—long-term use of the contraceptive pill may dramatically lower the risk of womb cancer (endometrial cancer). Published in Acta Obstetricia et Gynecologica Scandinavica, the study shows that women who use oral contraceptives for over a decade […]

They say breakfast is the most important meal of the day—and science is starting to prove why. A long-term study from the UK has found that skipping or delaying breakfast could increase risks of depression, poor oral health, and fatigue and even shorten life expectancy. This research underscores the growing field of chrononutrition—the science of […]

When we think of stroke prevention, oral health rarely comes to mind. But new research suggests that tooth loss could be a hidden predictor of stroke risk—and the connection is stronger than most realize. The Study at a Glance Researchers analyzed data from 23,473 adults in the U.S. through the National Health and Nutrition Examination […]

The concept of brain death has always been sensitive, lying at the intersection of medicine, ethics, law, and organ donation. Recently, the Supreme Court of India was asked to review a claim by a Kerala-based doctor who argued that brain death is a “fictitious concept” designed to facilitate organ trade. The Court’s response has reignited […]

The world faces a critical shortage of human organs for transplantation. Thousands die every year waiting for kidneys, livers, lungs, or hearts that never arrive. But science may have found a surprising ally: pigs. Through genetic engineering, researchers are now testing pig organs as potential replacements for failing human ones. This field—called xenotransplantation—could become one […]
