A new study followed people who had just been diagnosed with colorectal cancer. At the start, 411 patients gave blood samples and answered questions about how tired they felt. The researchers repeated the tests at 12 months (304 people) and again after two years (252 people). They also looked at a c
Research shows that body fat distribution might play a hidden role in brain health decades later. A long-term study tracked how waist size and overall weight changed in thousands of adults, then checked their blood for p-tau217—a protein often found in Alzheimer’s patients. The same group was also m
The way we think about cancer has changed. Doctors now know that who you are and how you live can shape the disease in ways that were once ignored. Sex—defined by chromosomes, hormones and body parts—has a direct impact on how tumors grow, how the immune system fights them, and how patients feel aft
Multiple sclerosis is a tricky disease to predict. Even with new medicines and lab tests, doctors still struggle to know how it will progress in each person. Traditional methods look mainly at how much damage the brain shows, but they miss other important clues. A group of researchers from a large
Doctors have long struggled to treat Lennox-Gastaut Syndrome, a tough-to-handle epilepsy that starts in childhood. Many patients deal with constant seizures that don’t go away even with strong medications. Recent research took a close look at two markers in the blood—neurofilament light chain and ca
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
