Nickel plays an important physiological role in plants, but how it is transported over long distances from stems and leaves to grains was poorly understood for more than 50 years. Now researchers have identified a key transporter gene, ZmNAET1, that controls nickel accumulation in cereal grains. They also uncovered how nicotianamine (NA), a plant-specific non-protein amino acid, mediates the long-distance transport of nickel and established the crucial role of nickel-dependent urease activity in amino acid metabolism, seed vigor, and yield formation.

Recent advances in optical cavity design facilitate the concentration of light in increasingly small volumes, allowing for strong light-matter interactions and prospects for quantum technological applications. However, the large bandwidths of these interactions are incompatible with widely used quantum models that fail to accurately predict the outcomes of experiments. By advancing the quantum theory of cavity photon dissipation, researchers have introduced an efficient tool for studying these emerging regimes of cavity quantum electrodynamics.
Scalable spatial arrays of squeezed light are needed for quantum sensing, imaging and information processing, yet maintaining uniform quantum properties across many channels is challenging. Researchers have generated a 30-channel array of polarization-squeezed light in a single paraffin-coated rubidium vapor cell. Thermal atomic motion transports and homogenizes long-lived ground-state coherence, creating global dissipative coupling that synchronizes measurable squeezing properties and enables higher effective state purity and faster recovery from perturbations as the array grows.
