NewsPlastic bottles transformed into Parkinson’s drug using bacteria
A drug to treat Parkinson’s disease can be made from waste plastic bottles using a pioneering method. The approach harnesses the power of bacteria to transform post-consumer plastic into L-DOPA, a frontline medication for the neurological disorder.

NewsHigh-fat diets cause gut bacteria to enter brain, study finds
A new study, performed using mouse models, establishes that live bacteria from an imbalanced gut microbiome can enter the brain via the vagus nerve. The vagus nerve connects the brainstem to the heart, lungs, and major abdominal organs, including the stomach, intestines, liver and more.

NewsBiocodex Microbiota Foundation announces open call for projects for $50,000 2026 USA Microbiome Research Grant
The Biocodex Microbiota Foundation, an independent organization founded by Biocodex, has opened applications for its 2026 USA research grant. The $50,000 grant will be awarded to a U.S.-based investigator studying the gut microbiota and its relationship to human health and disease.

NewsScientists discover ‘bacterial constipation’, a new disease caused by gut-drying bacteria
Scientists have found two gut bacteria working together that contribute to chronic constipation. The duo, Akkermansia muciniphila and Bacteroides thetaiotaomicron, destroy the intestinal mucus coating essential for keeping the colon lubricated and feces hydrated.

NewsNext-generation microbiome medicine may revolutionize the treatment of Parkinson’s and similar disorders
Scientists have engineered the probiotic bacterium Escherichia coli Nissle 1917 as a drug-delivery system that continuously produces and delivers the gold-standard Parkinson’s drug Levodopa, which is converted to dopamine in the brain. E. coli Nissle strain was chosen for its century-long record of safely treating gastrointestinal disorders in humans.

NewsHow to hack your microbiome for lifelong health
A new book, The Microbiome Master Key, dissects the latest microbiome research, dispels common myths and provides simple, science-backed tips on how to leverage your microbiome to promote healthy living and aging.

NewsOral bacteria linked to Parkinson’s via the gut-brain axis
Researchers have identified the mechanism by which metabolites produced by oral bacteria in the gut may trigger the development of Parkinson’s disease.

NewsSeventy-year-old Parkinson’s drug shows promise against tuberculosis
A medication developed in the 1950s to treat Parkinson’s disease may offer a powerful new tool in the fight against tuberculosis. The study found that benztropine can dramatically reduce levels of TB-causing bacteria by boosting the body’s natural immune response.

NewsAnti-neuroinflammatory natural products from isopod-related fungus now accessible via chemical synthesis
Herpotrichone is valued for its ability to suppress inflammation in the brain and protect nerve cells, but could only be obtained in minute quantities from fungi that are symbiotic with isopods. Researchers have succeeded in chemically synthesizing this rare natural product.

NewsStudy shows head trauma may activate latent viruses, leading to neurodegeneration
Researchers have uncovered mechanisms that may connect the dots between trauma and the emergence of disease, pointing to latent viruses lurking in most of our brains that may be activated by the jolt, leading to inflammation and accumulating damage.

NewsParkinson’s drug changes the gut microbiome for the worse due to iron deficiency
Scientists have revealed that the widely prescribed Parkinson’s disease drug entacapone significantly disrupts the human gut microbiome by inducing iron deficiency.
-
NewsAntibiotics and antifungals may slightly affect Parkinson’s risk, study finds
A study has found that people who took multiple courses of penicillin antibiotics had a modestly lower risk of developing Parkinson’s disease, a surprising finding that researchers say highlights the complex relationship between bacteria in the digestive tract and brain health.
-
NewsGut microbiome has central role in human aging
The gut microbiome holds a central role in human aging, influencing everything from metabolic function to immune health, a new review shows.

NewsFecal DNA testing could reduce global colonoscopy burden: experts
Experts gathered at the ICG 19 · Metagenomics for Health (ICG19·MH) & The 2nd MOHA Consortium have highlighted the global challenge of limited access to colonoscopy, the gold standard for CRC screening.
-
NewsTreating the gut-brain connection with B vitamins could help treat Parkinson’s Disease, study finds
Researchers found a reduction in the gut bacteria of genes responsible for synthesizing essential B vitamins and identified a relationship between the lack of these genes and low levels of agents that help maintain the integrity of the intestinal barrier.

NewsSARS-CoV-2 can infect dopamine neurons, causing senescence
A new study has reported that SARS-CoV-2, the virus that causes COVID, can infect dopamine neurons in the brain and trigger senescence - when a cell loses the ability to grow and divide.
-
NewsMicrobes in gastrointestinal tracts may foretell Alzheimer’s and Parkinson’s
Researchers have found that healthy, anti-inflammatory gut bacteria are less abundant among people who are diagnosed with Parkinson’s disease.
-
NewsMicrobial metabolites linked to Parkinson’s disease
Researchers have uncovered a microbial metabolite’s role in inducing Parkinson’s-like symptoms. This discovery could reshape our understanding of the environmental triggers of Parkinson’s disease.
-
NewsThree intestinal bacteria linked to dementia with Lewy bodies
Researchers have identified three bacteria linked to dementia with Lewy bodies: Collinsella, Ruminococcus, and Bifidobacterium, suggesting new avenues for diagnosis and treatment.

NewsNew research unit awarded €6m to investigate gut-brain axis
The German Research Foundation (DFG) is funding a new clinical research unit that will investigate the interaction between the digestive and nervous systems with reference to inflammatory and degenerative diseases, the first collaborative research group in Germany to explore the “gut-brain axis”.
