An ancient genetic event may hold the key to how plants survive in metal-contaminated environments. Scientists have discovered that a duplication of phytochelatin synthase (PCS) genes—crucial enzymes for detoxifying toxic metals—occurred millions of years ago and remains conserved in flowering plants today. These twin gene copies, known as D1 and D2, evolved distinct but complementary functions: while D1 plays a general role in detoxification, D2 exhibits exceptional catalytic activity against cadmium and arsenic. Functional tests in Malus domestica (MdPCS1, MdPCS2) and Medicago truncatula (MtPCS1, MtPCS2) revealed that both copies are indispensable for maintaining metal balance, unveiling a deep evolutionary strategy for resilience.

In a pioneering exploration of the evolving landscape of carbon fiber composite material recycling, researchers are leveraging bibliometric analysis to uncover the latest advancements and emerging hotspots in this critical field. The study, titled "Research Advances and Hotspot Evolution of Carbon Fiber Composite Material Recycling Based on Bibliometrics Analysis," is led by Prof. Da Chen from the Science and Technology Innovation Research Institute at the Civil Aviation University of China in Tianjin, China, and the Tianjin Engineering Research Center of Civil Aviation Energy-Environment and Green Development. This comprehensive analysis offers valuable insights into the current state and future directions of carbon fiber recycling research.

In the hunt for new therapeutics for cancer and infectious diseases, lasso peptides prove to be a catch. Their knot-like structures afford these molecules high stability and diverse biological activities, making them a promising avenue for new therapeutics. To better unleash their clinical potential, a team from the Carl R. Woese Institute for Genomic Biology developed LassoESM, a new large language model for predicting lasso peptide properties.
