Why This Flu Season Feels Worse: Subclade K and What It Means
What’s Making This Year’s Flu Season More Challenging Every year, the flu season brings a familiar mix of coughs, fevers, and fatigue. This year, many health experts describe the season as more intense for a larger portion of the population. The strongest threads in the story revolve around the genetic evolution of influenza viruses and…

Viruses in Space: How Microgravity Alters ISS Biology
What makes the ISS a unique microbial environment The International Space Station (ISS) operates as a closed ecosystem where humans, microbes, and surfaces constantly interact in ways that differ from Earth. In microgravity, fluids behave differently, air flows shift, and radiation exposure changes, all of which can influence how viruses and other microbes survive, replicate,…

Early Blood Test Signals Crohn’s Disease Before Symptoms
Overview: A Promising Tool for Early Crohn’s Detection Researchers are pursuing a simple blood test that could forecast Crohn’s disease long before patients notice symptoms. The test examines how a person’s immune system reacts to flagellin, a protein found on gut bacteria. In individuals who later develop Crohn’s, this immune response tends to be elevated…

Early Flagellin Response Test Promises Crohn’s Disease Prediction Before Symptoms
Breakthrough in Crohn’s disease prediction using the immune response A new blood test that measures a person’s immune reaction to flagellin, a protein on gut bacteria, is showing promise in predicting Crohn’s disease before clinical symptoms appear. Developed by a team led by Dr. Ken Croitoru, a clinician-scientist at the Lunenfeld-Taneau research institute, the test…

The Inflammation Link: How Long COVID May Be Fueled by Microclots and Immune Signals
Unraveling the biology of long COVID Long COVID remains a puzzling condition for millions who continue to experience symptoms weeks or months after a SARS-CoV-2 infection. Recent research suggests that multiple biological processes may overlap and amplify one another, creating a complex web that sustains fatigue, brain fog, shortness of breath, and other lingering effects.…

Unraveling Long COVID: Inflammation and Tiny Clots Behind Prolonged Symptoms
What Long COVID Might Be Telling Us About Our Bodies While most people recover from acute COVID-19 within a few weeks, a significant subset experiences lingering symptoms that can persist for months. Scientists are racing to understand the biology behind long COVID, and the leading theories point to several overlapping problems. Inflammation that stubbornly lingers,…

Long COVID: How Inflammation and Tiny Clots Might Drive Persistent Symptoms
Understanding Long COVID: Beyond the Initial Infection Long COVID remains a complex and evolving condition. While many people recover from the acute phase of COVID-19, a subset experiences persistent symptoms that linger for weeks or months. Scientists are now piecing together a multifaceted picture: lingering virus particles in the body, ongoing low-grade inflammation, and tiny…

New Study Suggests Microbe Sparks Early Stages of Ulcerative Colitis
Rethinking Ulcerative Colitis: A Microbe-Driven Beginning For decades, scientists have often described ulcerative colitis (UC) as a disease rooted in an overactive immune response or damage to the gut’s epithelial barrier. A new study, however, challenges this traditional view by proposing that the earliest steps of UC might be sparked by a microbial trigger before…

Microbes May Spark the First Stages of Ulcerative Colitis: A New Perspective
Rethinking Ulcerative Colitis: A Microbe-Driven Beginning Ulcerative colitis, a chronic inflammatory bowel disease, has long been understood through the lens of an overactive immune system or damage to the gut’s protective lining. A growing body of research, however, is shifting the focus toward the tiny inhabitants that dwell in the gut: microbes. In recent findings,…

Grey Hair Could Signal Lower Skin Cancer Risk: New Study
Grey Hair and Skin Cancer: What the Study Found Grey hair has long been viewed mainly as a sign of aging, but a new study suggests it might also carry information about how the body fights melanoma, the deadliest form of skin cancer. Researchers observed that individuals with grey or white hair tended to show…
