Accidental plant poisonings in France: Lessons from a decade of national toxicovigilance

PLANTS, PEOPLE, PLANET, EarlyView.
Accidental plant poisonings reveal how modern societies are losing everyday botanical knowledge once central to food and health safety. By analyzing a decade of French toxicovigilance data, this study shows that most severe cases arise from plant misidentification or misguided self‐medication.

Efficient water‐soluble blue/red‐emissive carbon dots matching plant absorption spectra: Synthesis, tunable control, and their applications in promoting plant growth

Responsive Materials, EarlyView.
Guided by the spectral demand of plant photosystems, this review summarizes the synthesis, emission regulation, dual‐emission design, and gram‐scale production of CDs for agricultural applications. Spectrally matched blue‐ and red‐emissive CDs enhance plant light utilization by converting underutilized light into photosynthetically active radiation and
