Antibiotics are drugs used to treat infections caused by bacteria and other microorganisms.

Machine learning speeds up AMP discovery for treating ulcerative colitis

Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by recurrent intestinal inflammation, abdominal pain and diarrhea.

New wound dressing targets infections while reducing antibiotic overuse

Biomedical engineers from Brown University have developed a new wound dressing material that releases antibiotic drugs only when harmful bacteria are present in a wound.

Weaning reshapes gut microbes to strengthen lifelong immune defenses

According to a team of researchers at Baylor College of Medicine, Tongji University and collaborating institutions, weaning or switching from milk to solid food in early life doesn't just change what babies eat, it helps reprogram the gut's immune defenses to mount faster and stronger responses that can last into adulthood.

Nature-inspired sensor detects molecules in blood with high sensitivity

A team led by La Trobe University has drawn inspiration from nature to develop a breakthrough sensor that can rapidly track tiny molecular changes in blood, paving the way to real-time, personalized medicine.

Gut-derived blood markers may help predict who develops coronary heart disease

Researchers used five prospective cohorts from the US and China to identify circulating gut microbiota-related metabolites linked to future coronary heart disease, then tested the findings through discovery, in silico validation, and targeted quantitative validation. The study ultimately highlighted nine metabolites associated with incident CHD, supporting a potential role for microbial metabolism in heart disease risk while not proving causation

New breath test could quickly diagnose bacterial infections

Infectious diseases are a major cause of death worldwide, and diagnosing bacterial infections remains a challenge in medicine.

New microbiome therapy improves autism symptoms in children

This study evaluates a new fecal microbiota transplant method, revealing significant symptom improvements in children with autism without invasive procedures.

How one antibiotic dose can reshape your gut microbiome for years

Long-term registry-linked analysis of nearly 15,000 adults shows that antibiotic use is associated with persistent changes in gut microbiome diversity and composition for up to 4–8 years. These effects vary by antibiotic class, with clindamycin, fluoroquinolones, and flucloxacillin showing the strongest and most sustained associations.

Scientists turn plastic waste into Parkinson’s drug levodopa using engineered bacteria

Researchers engineered a two-strain microbial system that converts PET-derived terephthalic acid into levodopa, overcoming key bottlenecks in transport and enzyme inhibition. The proof-of-concept process achieves high yields under mild conditions and demonstrates a potential route for upcycling plastic waste into valuable pharmaceuticals.

Scientists show gut bacteria can reach the brain in mice and reveal a potential vagus nerve pathway

Researchers found that very small numbers of gut bacteria can translocate to the brain in mice, particularly when gut barrier permeability increases due to a Paigen diet. Evidence suggests the vagus nerve may serve as a partial route for this gut-to-brain microbial movement.

Cambridge’s LED breakthrough reinvents drug synthesis

Scientists at the University of Cambridge have developed a new way to alter complex drug molecules using light rather than toxic chemicals – a discovery that could accelerate and improve how medicines are designed and made.

Swapping red meat for plant-based meat rapidly lowers a key heart risk metabolite, trial finds

A randomized crossover trial found that replacing red meat patties with processed plant-based meat alternatives for six days significantly lowered circulating trimethylamine N-oxide (TMAO), a gut-derived metabolite linked to cardiovascular risk. The plant-based phase also produced modest reductions in cholesterol markers but slightly increased weight and NT-proBNP, possibly due to higher sodium intake.

Gut microbes may drive memory decline during aging by disrupting vagal brain signaling

Researchers identified in mice a microbiome–gut–brain pathway in which age-associated changes in gut microbes increase medium-chain fatty acids that impair vagal sensory signaling and hippocampal activity. These interoceptive disruptions weaken memory formation, revealing a microbial mechanism that contributes to cognitive decline during aging.
