Cholera germs have a smart trick to protect themselves. They carry a built-in gene storage system that holds hundreds of spare parts, mostly unused. A small portion of these genes help fight off viruses. Normally, stressed bacteria shuffle these genes around to pick the best ones. But cholera germs
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
Sweet potatoes aren’t just orange or white anymore. Purple varieties pack a powerful antioxidant punch thanks to anthocyanins, the pigments that give blueberries and red cabbage their deep colors. But when these plants don’t get enough phosphorus—a key nutrient—they change how they make these health
Out in the Mediterranean’s murky waters lives a creature most people never notice. Smaller than a thumbnail, this shrimp-like bug—Idotea balthica—quietly holds more genes than humans do. Researchers only noticed because its genetic mix was too complex to ignore. Even now, one-third of those genes mi
Scientists found a protein in farmed tilapia that acts like an infection alarm. Called IRF5, it helps fish cells recognize threats like viruses and bacteria. When attackers show up, IRF5 gets more active in the fish’s head kidney—a place where immune cells are stored. This isn’t just some minor reac
A large study looked at how people’s genes that favor coffee drinking might affect hidden heart disease. Researchers followed 24, 835 adults in Sweden and used imaging tests to check for early plaque in heart arteries and the neck’s carotid artery. Participants reported how often they drank coffee,
Polycystic ovarian syndrome is more than a collection of cysts; it’s a complex mix of hormones, genes and everyday habits that can disrupt a woman’s health. The first thing doctors notice is too much male hormone in the body, a condition called hyperandrogenism. This excess can lead to acne, hair
A key chemical tag on messenger RNA, called m6A, is common across all eukaryotes. Cells control how much of this tag appears by adding or removing it with specialized enzymes known as writers and erasers. In plant cells, the chloroplast—a site of photosynthesis—contains many mRNAs that carry this ta
The study looks at what university students think about pre‑marriage screening in Chattogram, Bangladesh. It focuses on how much they know, their attitudes, and what they feel about the tests that catch genetic or sexually transmitted diseases before couples marry. Many people in Bangladesh sh
Lipedema is a puzzling condition. It mostly affects women. It causes fat to build up in a certain way. This fat is often painful and hard to get rid of. Doctors and scientists are still trying to figure out why this happens. Recent studies have looked at how genes and metabolism are involved. They
