Des chercheurs mexicains développent des antibiotiques à partir de venin et de piments

Des scientifiques de l'Université nationale autonome du Mexique ont créé trois nouveaux antibiotiques en utilisant des composés extraits de venin de scorpion et de piments habanero. Ces travaux ciblent la tuberculose ainsi que d'autres bactéries devenues résistantes aux traitements actuels.

Des chercheurs de l'Université nationale autonome du Mexique ont identifié de nouvelles approches pour lutter contre la résistance bactérienne. Ils ont mis au point trois antibiotiques dérivés directement du venin de scorpion et des piments habanero.

Researchers at the University of Kent, working with University College London, report that madecassic acid—a compound derived from the medicinal herb Centella asiatica and widely used in skincare—can inhibit the growth of antibiotic-resistant E. coli by targeting a bacterial respiratory system not found in humans or other animals.

Scientists have discovered a 5,000-year-old bacterium in a Romanian ice cave that resists several contemporary antibiotics. The microbe, isolated from permafrost, carries over 100 resistance genes and could inhibit dangerous superbugs. This finding highlights natural evolution of resistance and potential biotechnological applications.

Scientists at the Weizmann Institute of Science in Israel have modified tobacco plants to produce five powerful psychedelic compounds typically found in mushrooms, plants, and toads. The technique uses temporary genetic changes to create a sustainable source for research and potential medicines. Experts say this could simplify production compared to chemical synthesis or harvesting from nature.

Researchers at the University of Queensland have discovered that many scorpion species strengthen their claws and stingers using blends of iron, zinc, and manganese. The metals concentrate in the tips and cutting edges, making these weapons tougher, similar to a steel-capped boot. The findings come from examining 18 species worldwide.

Researchers have detected multiple antibiotics in Brazil's Piracicaba River, accumulating in water, sediment, and fish, especially in the dry season. A banned drug, chloramphenicol, was found in lambari fish sold for consumption. Experiments with the aquatic plant Salvinia auriculata showed it can remove some antibiotics but may alter fish exposure.
