Most of us think that twins are only those who are born together and look alike. But what if I told you — some twins live inside the same person? This is not science fiction. It is real biology. And it is called mosaicism and chimerism — two strange and fascinating conditions that happen naturally in some people. These are like “invisible twins” hidden in one body! 🧬 What is Mosaicism? Mosaicism happens when a person has two or more types of cells in their body, but all coming from the same fertilised egg. Normally, one fertilised egg grows into one person with one type of DNA in every cell. But sometimes, a mutation happens during early development, and some cells change. So the person becomes a mosaic — like a rangoli made of different colours. 📍 Example: One part of the skin may look different from the other. Some people may have different eye colours or patches of lighter skin. 🧬 What is Chimerism? Chimerism is even more fascinating — and rare. It happens when two separate ferti...

🌕 Imagine this: The year is 2035. Inside a dome-shaped habitat on the Moon, an astronaut carefully trims a tiny plant just 10 centimeters tall. Floating beside her in microgravity is a translucent container filled with vibrant green shoots. They are not just any plants—they’re rice. But not the sprawling, water-loving kind you know. These are Moon-rice , the result of years of research, engineering, and dreams once thought too big. Now fast-forward to today—July 2025. Scientists on Earth are perfecting that very dream. Welcome to the Moon-Rice project, a rare and thrilling leap in space biotechnology that may reshape how we think about food, survival, and the future of farming itself. 🚀 What is Moon-Rice? Moon-Rice is a space agriculture initiative born out of necessity—and fueled by innovation. Spearheaded by the Italian Space Agency (ASI) in collaboration with the University of Milan , University of Rome “Sapienza” , and University of Naples “Federico II” , the project aims to...

California, 1976. A quiet suburb is jolted awake by a scream in the night. A man in a ski mask slips silently out of the backdoor, leaving behind shattered lives and no trace of his identity. It wouldn’t be the last time. For the next 10 years, he stalked neighborhoods across the state — attacking in the dark, vanishing before sunrise. People locked their windows. Men slept with baseball bats. Women lived in fear. He was called many names — The East Area Rapist, The Original Night Stalker, and finally, The Golden State Killer. But no one knew who he really was. Until DNA spoke up. 🧬 The Clue That Waited in Silence In the 1970s and 80s, DNA science was just a distant dream. But investigators, unknowingly ahead of their time, preserved physical evidence — tiny samples that held within them a silent witness: the killer’s DNA. Years passed. Technology evolved. DNA became the new fingerprint. By the early 2000s, scientists extracted a DNA profile from a crime scene sample — a perfect match...
