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.

Tobacco plants engineered to produce five psychedelic drugs

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.

Spice compounds synergize to boost anti-inflammation hundreds of times

09 de abril de 2026 Reportado por IA

Researchers at Tokyo University of Science have discovered that combining common plant compounds from mint, eucalyptus, and chili peppers dramatically enhances their anti-inflammatory effects in immune cells. Certain pairings amplified the response several hundred-fold compared to individual use. The findings, published in the journal Nutrients, suggest potential for new dietary approaches to combat chronic inflammation.
