In the weeks before a big fight, some fighters do more than just train. They track their body’s hidden signals with hormone tests. This is a new way to know when the body is ready or overworked. Hormones like testosterone, cortisol and melatonin tell a lot. Testosterone helps build muscle and keep
Researchers are studying a rare form of Alzheimer’s that runs in families, where symptoms almost always start at the exact same age. This special case helps scientists spot brain changes years before people feel sick. While doctors can now detect tiny clues in blood tests, experts still don’t fully
Scientists have found a new way to learn about the habits of city residents by looking at their sewage. The technique, called wastewater‑based epidemiology, usually tracks drug use but now also measures food and drink markers. A fresh laboratory test can spot more than 40 different substances in raw
Scientists are exploring fresh markers in the body that could help spot problems linked to how we live. These new tools look at tiny molecules and signals in blood, sweat or even breath that change when we eat poorly, sit too long or smoke. By catching these clues early, doctors might offer advice t
Scientists studied how a common steroid, prednisolone, affects bone health in young rats. They looked at three blood markers that show how fast bones build and break down: a protein from new bone, another marker of bone strength, and one that signals bone loss. The team also checked the bones with d
Scientists have created tiny DNA loops that turn on only when they meet cancer cells. These loops, called minicircles, are built with a special design that keeps them stable and lets them stay in the body for a long time. When cancer is present, the loops become active and release signals that can b
Type 2 diabetes is a complex condition. It's not just about sugar levels. Blood pressure and insulin resistance play big roles too. Scientists are looking at new ways to understand these connections. Insulin resistance is a key issue. It's when the body doesn't respond well to insulin. This can lea
Researchers in Sweden are looking into whether blood tests can help predict pregnancy complications, specifically preeclampsia, which is a type of high blood pressure during pregnancy. They are focusing on a specific time frame, between 24 and 29 weeks of pregnancy. The goal is to find out if certai
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
People with Alzheimer's disease and related dementias (ADRD) often show small changes in behavior before major symptoms appear. These changes can include sleep problems, less time spent outside, and different internet habits. Spotting these shifts early can help doctors act faster and slow down the
