نجح علماء في جامعة المكسيك الوطنية المستقلة في ابتكار ثلاثة مضادات حيوية جديدة باستخدام مركبات مستخلصة من سم العقارب وفلفل الهابانيرو، وذلك في إطار جهود تهدف إلى مكافحة مرض السل والبكتيريا التي طورت مقاومة للعلاجات الحالية.
حدد باحثون من جامعة المكسيك الوطنية المستقلة طرقاً جديدة لمواجهة المقاومة البكتيرية، حيث أنتجوا ثلاثة مضادات حيوية مستمدة مباشرة من سم العقارب وفلفل الهابانيرو.

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.
