Bogland tormentil: a wildflower unlocking new ways to fight resistant bacteria

Lab tests show tormentil root extracts from bogland inhibit growth of antibiotic‑resistant bacteria, reduce biofilm formation, and boost the effectiveness of the antibiotic colistin at low doses. The active compounds ellagic acid and agrimoniin appear to work by iron chelation, starving bacteria of a key nutrient and hindering growth, pointing to a potential plant‑derived route to new antimicrobials and combination therapies.

Honey: potent wound ally but not a universal cure

Honey has antimicrobial components and may aid wound healing, but it is not an antibiotic and its effects vary by source; medical-grade honey is used topically for wounds due to sterilization requirements, while raw honey can carry botulism spores and should not be given to infants under 12 months. Evidence for cough relief and gut health is limited and inconclusive, and standardizing non-Manuka honeys for clinical use remains challenging.

Intellectin-2: A Dual-Action Gut Defender That Strengthens Mucus and Kills Bacteria

MIT researchers identify intelectin-2 as a gut lectin that both reinforces the mucus barrier and directly traps and neutralizes a broad range of bacteria, suggesting a host-derived antimicrobial approach that could help prevent infections and support mucus integrity in inflammatory bowel disease.

Scientists Discover Potent New Antibiotic Hidden in Nature

Researchers discovered a potent new antibiotic, pre-methylenomycin C lactone, in a bacteria species studied for decades, which shows promise against resistant bacteria like MRSA and VRE, and remains effective after prolonged exposure, highlighting a new approach to antibiotic discovery by exploring biosynthetic intermediates.

Natural Plant Compound Offers Hope for Gum Disease Treatment

Researchers in Brazil have developed a powdered form of the natural compound morin, found in fruits and nuts, which shows promise as a non-antibiotic treatment for gum disease. Encapsulated in a controlled-release system, this powder could help treat periodontal bacteria, especially for individuals with reduced motor skills, and offers a potential alternative to traditional treatments with fewer side effects.

"Copper-infused Vase: The Secret to Prolonging Flower Lifespan"

Glasgow-based design company POTR Pots has created the LetterBox Vase, inspired by a centuries-old technique of using copper to keep flowers fresh. By dropping a pre-1992 1 or 2 pence coin from The Royal Mint or a pre-1982 penny from the U.S. Treasury into the vase, the copper acts as a natural antimicrobial, killing bacteria and extending the life of the flowers. The vase features a copper stem, a self-cleansing design made from recycled materials, and a flat-pack design to reduce carbon footprint. The initiative aims to reduce premature flower wastage and is available in three pastel colors.

Glass fibers and sex differences aid in chronic wound healing: Study

Researchers at the University of Birmingham have demonstrated that bioactive glass doped with silver can provide long-lasting antimicrobial wound protection. The study showed that specific preparation, storage, and application techniques can minimize the transformation of silver ions to silver chloride and retain antimicrobial activity. Bioactive glass has been used for years in bone grafting, and the researchers are now exploring its potential for dental surgery and wound care. The team is looking to collaborate with companies to develop their promising new biomaterials.
