A newly identified bacteriophage could offer a targeted alternative to antibiotics in the fight against foodborne Salmonella. According to researchers, phage W5 was able to break down stubborn biofilms and reduce contamination on foods and processing surfaces, pointing to new phage-based disinfection strategies for safer, cleaner and more sustainable food production.

Researchers at McMaster University have developed a new generative artificial intelligence (AI) model capable of drastically speeding up drug discovery — and, in early tests, it has already designed a brand-new antibiotic.

Altering the gut microbiome could help the brain recover after traumatic injury. Researchers at Houston Methodist report in Communications Biology that short-term antibiotic treatment reduced neuroinflammation and tissue damage in experimental models of traumatic brain injury.

Newly identified compounds appear effective against drug-resistant bacteria. The technique used to reveal them could uncover many more antibiotics, as well as help illuminate a previously hidden microbial world.

A new open-access review warns that heavy metals, microplastics, and antibiotic resistance genes are increasingly accumulating together in greenhouse farming systems, creating combined risks for soil health, crop safety, and sustainable food production that current assessment tools fail to fully capture.

To outpace rising antibiotic resistance, researchers at Rockefeller University have developed a platform that scans environmental DNA to identify resistance genes before they reach the clinic, helping design antibiotics that are built to last.

Biodegradable plastics are not always safer for rivers and oceans, according to a new study that tracked how different plastics change the risk of antibiotic resistant bacteria over time in a real river.

From tuberculosis to lung cancer, a new personalised lung-on-chip model opens the door to studying respiratory diseases in a realistic human system for the first time.

Scientists have engineered strains of a naturally occurring beneficial gut bacterium into a programmable “living medicine” to treat hepatic encephalopathy, a severe brain dysfunction linked to liver failure.

Children, older adults and people who spend most of their time indoors may face elevated health risks from unseen household contaminants. Researchers now warn that modern buildings can trap and transform chemicals in ways that amplify long-term exposure.
