NewsToxic gut bacteria may drive ulcerative colitis by killing protective immune cells
A toxin-secreting gut bacterium may fuel ulcerative colitis by killing protective immune cells that maintain intestinal homeostasis, according to a new study. The findings suggest potential for new treatment strategies.

NewsBacteria ‘pills’ could detect gut diseases — without the endoscope
Researchers report that they’ve developed a sensor made of tiny microspheres packed with blood-sensing bacteria that detect markers of gastrointestinal disease. Taken orally, the miniature “pills” also contain magnetic particles that make them easy to collect from stool. Excreted from mouse models with colitis, the bacterial sensor detected gastrointestinal bleeding within minutes.

NewsTraces of bacteria inside brain tumors may affect tumor behavior
Scientists have uncovered unexpected traces of bacteria within brain tumors. This discovery offers new insights into the environment in which brain tumors grow and sets the stage for future studies seeking to improve treatment outcomes.

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.

NewsNew DNA analysis approach could transform understanding of disease evolution
By adapting techniques originally used to study ancient DNA from archaeological specimens, researchers were able to recover genetic information from nearly century-old medical samples.

NewsThe link between the gut microbiome and autism is not backed by science, researchers say
There’s no scientific evidence that the gut microbiome causes autism, a group of scientists argue in an opinion paper. They warn that conclusions that supported this hypothesis are undermined by flawed assumptions, small sample sizes, and inappropriate statistical methods.

NewsScientists find way to find the gut microbiome into a longevity factory
A team of researchers has found a way to turn the bacteria living in the digestive tracts of animals into factories that can produce compounds that promote longevity in their hosts—showing a potential new drug development strategy.

NewsScientists tie lupus to a virus nearly all of us carry
The Epstein-Barr virus is directly responsible for commandeering what starts out as a minuscule number of immune cells to go rogue and persuade far more of their fellow immune cells to launch a widespread assault on the body’s tissues, a study has shown.

NewsScientists harness algae for a greener way to create functional gold nanoparticles
Researchers have pioneered a novel, sustainable method for synthesizing functionalized gold nanoparticles (AuNPs) using microalgae. This approach not only avoids the harsh chemicals used in conventional methods but also produces AuNPs that are more stable and less toxic to healthy cells.

NewsHuman PARP gene could be novel target for viral diseases or immune-mediated disorders
Researchershave discovered a human gene, the protein PARP14, plays a role in regulating interferon, part of the body’s innate immune system. Their study could guide development of antiviral therapies for several groups of viral infection.

NewsSingle-cell insights reveal how HPV status reshapes penile tumor immunity
A study found that HPV-positive tumors in penile squamous cell carcinoma cases contained fewer proliferative macrophages and less exhausted CD8+ T cells, along with stronger chemokine signaling, revealing distinct immune remodeling associated with HPV infection.

NewsGut microbiota: implications in pathogenesis and potential therapeutic target in primary biliary cholangitis
A new review synthesizes current evidence on gut microbiota dysbiosis in PBC, elucidates its pathogenic mechanisms, and explores its potential as both a diagnostic biomarker and a novel therapeutic target.

NewsLow-dose cannabis compound reduces side effects of HIV treatment
Long-term, low doses of THC mitigate many harmful side effects and inflammation caused by HIV and antiretroviral therapy (ART). Benefits included increased production of serotonin, while inflammation, cholesterol and harmful secondary bile acids were all reduced.

NewsThe ‘MDME Axis’: A new view on how microbial metabolites epigenetically shape host health
A review introduces the ’MDME Axis’, a new framework explaining how metabolites from the gut microbiome epigenetically reprogram our genes, influencing host health and disease.

NewsTemporary benefit for immune system in early HIV treatment, but dysregulation returns
A study investigated whether immune dysregulation can be prevented by starting HIV medication immediately after infection. Six months after this early treatment, the immune system did indeed work as in people without HIV, but in the longer term, the immune system was disrupted again.

NewsAncient viral DNA shapes modern human placentas
Researchers have uncovered how ancient viral DNA controls a gene linked to placenta development and pre-eclampsia, a life-threatening pregnancy disorder. The research could help identify pre-eclampsia risk much earlier.

NewsAccessible imaging technique can predict cardiac risks in patients with Chagas disease
A simple imaging exam capable of assessing myocardial deformation during contraction has emerged as a promising tool for predicting the risk of cardiac complications in patients with chronic Chagas disease.

NewsNew insights on gut microbes that prevent formation of cancer-causing compounds
Gut microbes metabolize dietary nitrates and nitrites and prevent the formation of cancer-causing compounds called nitrosamines. New research sheds light on these processes and pinpoints which types of bacteria are most important.

NewsResearch finds higher rare risk of heart complications in children after COVID-19 infection than after vaccination
A whole-population study showed that although these conditions were rare, children and young people were more likely to experience heart, vascular or inflammatory problems after a COVID-19 infection than after having the vaccine — and the risks after infection lasted much longer.

News‘Rotten egg’ gas could be the answer to treating nail infections, say scientists
Hydrogen sulphide, the volcanic gas that smells of rotten eggs, could be used in a new treatment for tricky nail infections that acts faster but with fewer side effects, according to scientists.
