A charge-density-wave topological semimetal

Researchers have discovered a new material that exhibits both charge density wave and topological metal properties, featuring Weyl points and immense chiral charges. The discovery reveals an intimate connection between topology and electron correlations, opening up avenues for observing axion electrodynamics in condensed matter systems.

Expanding the boundaries of CO2 fixation

Researchers have engineered a new-to-nature metabolic connection, the TaCo pathway, which fixes CO2 instead of releasing it in photorespiration. This synthetic pathway is more energy-efficient than any other proposed alternative, with potential applications in improving crop yield and recycling polyethylene terephthalate (PET).
