No Evidence the Gut Microbiome Causes Autism

Experts reviewing decades of research conclude there is no scientific evidence that the gut microbiome causes autism. They highlight major flaws in observational studies, mouse experiments, and clinical trials, including inadequate sample sizes and contradictory findings.

Why Women Face Worse Long COVID

New research reveals that women with long COVID show distinct biological disruptions — including gut inflammation, anemia, and abnormal hormone levels — that may explain their heightened and persistent symptoms. These findings emerged from immune, biomarker, and genetic analyses in people one year after infection.

Toddler Gut Bacteria Linked to Childhood Anxiety and Depression

A new study suggests that a child’s gut microbiome at age 2 may influence their emotional health years later. Researchers found that higher levels of bacteria from the Clostridiales order and Lachnospiraceae family were linked to stronger connectivity across emotion-related brain networks and a higher risk of anxiety and depression symptoms by age 7½.

Gut Fungus Found to Disrupt Brain’s Alcohol Reward Pathway

A new study reveals that an overgrowth of Candida albicans, a common gut fungus, may alter the brain’s dopamine reward circuitry and influence alcohol consumption. Researchers found that as fungal populations increased, they triggered production of inflammatory molecules called PGE2, which crossed into the brain and changed dopamine signaling in the dorsal striatum.

Gut Microbes May Shape Brain and Behavior Through Hidden Mutations

In a groundbreaking study using Merino sheep, researchers uncovered that tiny genetic variations within gut microbes can influence brain-related behavior. By sequencing over 5,000 microbial genomes—including 3,500 never before reported—they linked single nucleotide variations (SNVs) in microbes to neurobehavioral traits and plasma metabolites tied to brain function.

Reelin Shows Promise for Healing Both Gut and Depression

A new study reveals that the protein Reelin may hold the key to treating both “leaky gut” and major depressive disorder. Chronic stress lowers Reelin levels in the gut, weakening the intestinal barrier and allowing toxins to trigger inflammation that worsens depression.

Sugary Drinks Linked to Depression Through Gut Microbiome

A new study shows that sugary drinks don’t just affect physical health—they may also raise the risk of depression in women by disrupting the gut microbiome. Researchers found that high consumption of soft drinks was linked to both a greater likelihood of major depressive disorder and more severe symptoms, particularly among women.

Gut Microbes May Hold the Hidden Key to Why We Sleep

A new study shows that bacterial cell wall molecules, specifically peptidoglycan, are present in the brain and fluctuate with sleep cycles. This finding supports a hypothesis that sleep is not solely brain-regulated but arises from the interplay between the body and its microbiome.

Oral Bacteria May Trigger Parkinson’s Disease

Scientists have uncovered a direct link between oral bacteria and Parkinson’s disease. They found that Streptococcus mutans, best known for causing cavities, can settle in the gut and release metabolites that reach the brain.

AI Reveals Bitter Taste Receptors’ Hidden Role in Gut-Brain Health

Researchers used AlphaFold3, the latest AI-based protein modeling system, to predict the structures of all 25 known human bitter taste receptors (T2Rs). Compared with AlphaFold2, AF3 consistently generated more accurate structural predictions when benchmarked against experimentally determined data.

Gut Problems in Autism Linked to Sleep, Behavior, and Sensory Challenges

A long-term study tracking 475 children found that autistic children are far more likely to experience persistent gastrointestinal issues than their peers. These symptoms often co-occur, persist across childhood, and strongly relate to challenges with sleep, communication, behavior, and sensory processing.

Gut Immune Cells Found Migrating to Alzheimer’s Brain

Researchers have uncovered a surprising link between gut immune cells and the brain in Alzheimer’s disease. In mice, antibody-producing B cells that normally reside in the gut were found migrating into brain border regions, influenced by chemokine signals from inflammatory brain cells.
