On a seemingly ordinary day, a young, healthy individual may suddenly experience crushing chest pain—a symptom most people associate with long-term heart disease. Yet in some cases, the cause is not clogged arteries or years of unhealthy lifestyle choices, but a little-known and unpredictable condition called Spontaneous Coronary Artery Dissection (SCAD) . SCAD is an uncommon but increasingly recognized cause of heart attacks, particularly among women under the age of 50. Un

“I’m not bald. I’m just taller than my hair.” “His head is brighter than my future.” While often used in comedic punchlines, the true struggles and sufferings behind hair loss are not something anyone can judge without having experienced it themselves. Alopecia (the medical term for hair loss), suffered by over 50 million men and 30 million women in the United States alone, is not only prevalent but also has been documented throughout human history, yet no single remedy has

If you’ve ever been interested about reproduction or inheritance, you probably think that the DNA is the sole messenger for genetic traits. That’s not completely wrong, but recently, a group of scientists in Virginia discovered that the trait of longevity can be passed down without the alteration of DNA but with chemical signals inside cells. The key lies in lysosomes, which were thought to be merely the cell’s recycling site. In the Wang Lab at HHMI's Janelia Research Campu

Perfusion in spinach leaf (Worcestor Polytechnic Institute) When you look at a spinach leaf, you would probably think of a salad or a side dish, not a future medical tool. However, scientists have found that the structure of the spinach leaf could one day help repair damaged human hearts. A major challenge in the cardiology department is to find a way to grow thick, strong heart tissue in a lab to use to support a damaged heart. When someone experiences a heart attack, heart

After discovering remedies for smallpox, developing antibiotics, and pioneering vaccines that have saved millions of lives, humans are still facing one of the greatest medical challenges of all: cancer. Cancer, a disease characterized by the uncontrollable growth and spread of abnormal cells, remains one of the most feared illnesses worldwide, largely because there is still no single, definitive cure that works universally and without severe side effects. Current treatments

For many years, skin cancer was viewed primarily as a disease of older adults. However, epidemiological data show that melanoma is now one of the most common cancers diagnosed in adolescents and young adults in several countries. In high-UV regions such as Australia, melanoma is among the leading cancers affecting individuals aged approximately 15–39 (Australian Institute of Health and Welfare, 2023). Similar patterns have been reported in other populations. A major biologica

Millions of lives are lost during accidents and wars – not because injuries are fatal, but because bleeding is uncontrolled. Before patients reach a hospital, the available treatments are just bandages and cotton gauze. These rely on manual pressure, exhibiting poor hemostasis, or the mechanism that leads to cessation of bleeding from a blood vessel. They frequently stick to the blood clot and its removal can disrupt new tissues, trigger re-bleeding, and leave fibrous residues

Immortality. The distant hope that humans have pursued for centuries has long been confined to mythology, religion, and science fiction. From the elixirs sought by ancient emperors to modern anti-aging industries, the desire to overleap biological limits remains deeply rooted in human curiosity. In recent decades, however, this aspiration has begun to shift from imagination to scientific investigation. At the center of this discussion lie telomeres and telomerase, microscopic
