How Gut Worms Shape Battles Between Good and Bad Bacteria
Did you know? Parasitic worms in your gut can actually help fight off harmful bacteria by reshaping your immune system and supporting protective microbes.
-
Pregnancy Rewires the Brain Alongside the Entire Body
Did you know? Pregnancy doesn't just change hormones—it triggers coordinated remodeling across the brain, immune system, blood vessels, and microbiome all at once.
-
Rare bile duct disease links gut inflammation to liver failure
Surprising finding: 50-80% of people with primary sclerosing cholangitis, a rare liver disease that slowly destroys bile ducts, also have inflammatory bowel disease — and researchers now believe the gut microbiome plays a crucial role in both conditions.
-
Your Immune System Remembers — Even the 'Innate' Parts
Did you know? Your innate immune cells can be 'trained' by past infections and exposures, reshaping how they respond to future threats through changes that last from infancy into old age.
-
Living with Dogs May Have Reshaped Human Biology Over Millennia
Quick fact: Scientists now propose that 20,000+ years of living with dogs may have left detectable biological marks on human stress responses and immune systems through changes in gene regulation—not DNA itself.
-
After-Meal Inflammation in Obesity Shaped by Diet and Gut Health
Quick fact: People spend most of their day in a 'postprandial' state — the hours after eating — when obesity-related inflammation peaks due to interactions between gut bacteria, fat tissue, and what's on the plate.
-
Five Hidden Factors Linked to Type 2 Diabetes Risk
Surprising finding: Beyond diet and exercise, five biological factors—mitochondrial dysfunction, obesity, gut microbiota changes, oxidative stress, and inflammation—are now recognized as key contributors to type 2 diabetes development.
-
Skin Bacteria May Influence Risk of Squamous Cell Carcinoma
Did you know? The community of bacteria living on your skin may influence your risk of developing cutaneous squamous cell carcinoma, the second most common skin cancer, by affecting how your immune system responds to tumor development.
-
Your Gut, Brain, and Immune System May Form One Super-Network
Quick fact: Scientists now propose that the gut microbiome, cannabinoid signaling, and immune system function as a single unified feedback network that determines whether your body stays healthy or slides toward chronic disease.
