Researchers have created a smart wound dressing that can sense when harmful bacteria are present and respond by releasing antibiotics only when needed. Biomedical engineers at Brown University have created a wound dressing that releases antibiotics only when harmful bacteria are detected. In a new study, the team found that the material may quickly eliminate [...]

Researchers have uncovered why a common and costly dental implant infection often resists antibiotics. Dental implants have helped tens of millions of people regain a full set of stable, functional teeth, something traditional dentures cannot provide. However, between 10% and 20% of implant recipients eventually develop peri-implantitis, a serious infection that damages the jawbone around [...]

A new study suggests the gut microbiome may retain long-term signatures of past medication use, with some drugs leaving detectable effects years after treatment ends. Your gut may carry a record of medications you stopped taking years ago. A large study from the University of Tartu Institute of Genomics suggests that prescription drugs can leave [...]

Scientists found hidden antibiotics building up in rivers and fish, raising new concerns about pollution and food safety. Scientists from the Center for Nuclear Energy in Agriculture at the University of São Paulo (CENA-USP) have discovered residues of several antibiotic types in the Piracicaba River, one of the main rivers in São Paulo state, Brazil. [...]

A popular K-beauty ingredient could become an unexpected weapon against superbugs. Madecassic acid is best known in Korean skincare as a soothing “hero ingredient,” but scientists now believe it could also help combat antibiotic-resistant bacteria. Researchers at the University of Kent have discovered that this naturally occurring compound may offer a promising new approach in [...]

A naturally derived molecule shows promise in blocking critical behaviors that bacteria rely on to cause disease. Drug-resistant bacteria are quietly reshaping modern medicine, turning once-treatable infections into serious threats. Among the most concerning is Staphylococcus aureus, or “staph,” a microbe that commonly lives on the skin but can trigger dangerous infections if it enters [...]

A familiar compound found in everyday foods may hold unexpected potential in the fight against antibiotic resistance. A compound found in everyday foods may offer a new way to slow one of the most urgent threats to modern medicine. Researchers report in Engineering that cinnamic acid, a natural substance present in cinnamon and widely used [...]

A traditional medicinal plant, tormentil, shows promise against antibiotic-resistant bacteria in laboratory tests. Its compounds work by limiting bacterial growth and boosting antibiotic performance. Before the development of modern antibiotics, plant-based remedies were commonly used to treat infections. One such plant is tormentil (Potentilla erecta), a small yellow wildflower found across…

An everyday medication may hold untapped potential against one of the most difficult-to-treat bacterial threats. Antibiotic-resistant bacteria continue to outpace modern medicine, causing more than 2.8 million infections and over 35,000 deaths each year in the United States alone. Among the most concerning is methicillin-resistant Staphylococcus aureus, or MRSA, a type of staph bacteria that [...]

Plant-derived phytochemicals support lasting pig growth and gut health, outperforming antibiotics over time. Efforts to reduce reliance on antibiotic growth promoters in modern pig farming are increasingly turning to plant-derived essential oils as a promising alternative. These natural compounds may offer lasting benefits for animal health and performance. A rare long-term public study led by…

A detailed 3D map of a bacteria-hunting virus reveals ancient origins and new promise against superbugs. A research team led by the University of Otago – Ōtākou Whakaihu Waka has created a highly detailed structural blueprint of a bacteriophage, a type of virus that infects bacteria. The work strengthens the potential of these viruses as [...]

As the Earth becomes hotter, we’re seeing more floods and droughts. Flooding can make superbugs spread faster and further. And heat helps germs adapt faster
