BLACK MARKET IN P. "That phosphate is free to move between plants was demonstrated when radioactive phosphorus applied to the leaves of one plant, was shortly after application discovered in the shoots of neighbouring plants." https://lnkd.in/en3p-yV View in LinkedIn

BLACK MARKET IN P. "Phosphorus was apparently transported via underground mycorrhizas, as phosphate in direct contact with soil is immediately adsorbed to soil particles and does not move any more." https://lnkd.in/en3p-yV View in LinkedIn

MINERAL BALANCE. "When soil resources, such as P or N, limit photosynthesis, C is in excess. Mycorrhizal fungal hyphae explore the soil volume for P and N, and transport the nutrient (over distances of cm to m) in exchange for excess plant C. Mycorrhizal hyphae are more efficient at exploring the soil volume than even fine roots. As long as P or N are limiting, plants will support mycorrhizal fungi." https://lnkd.in/e7Tq5KC View in LinkedIn

MINERAL SUPPLY. "The crucial role of mycorrhizal fungi in improving the mineral nutrition of their host plants is well established. Mycorrhizal roots take up P, N, Zn, Cu, Ni, S, Mn, B, Fe, Ca, and K from soil more efficiently than nonmycorrhizal roots, especially at low fertility levels." https://lnkd.in/e7Tq5KC View in LinkedIn

MINERAL SUPPLY. "The external hyphae of AM fungi contribute up to 80% of the P, 10% of the K, 25% of the Zn, and 60% of the Cu absorbed by the plants, and 25% of plant N." https://lnkd.in/e7Tq5KC View in LinkedIn

METAMATERIALS have other applications beyond optical cloaking, including seismic cloaking, acoustic cloaking, acoustic levitation, time cloaking, artificial magnetism, and synthetic wormholes. This splendid menu of ridiculously far-out technology is in various stages of experimental validation. We live in interesting times. This is a preview of upcoming topics. View in LinkedIn

"RELATED CONCEPTS, such as invisible particles, non-radiating source distributions, low-scattering antennas, and the non-uniqueness of the inverse scattering problem have been investigated by the scientific community over the last century." https://lnkd.in/eV48D4C View in LinkedIn

NEW FRONTIER. "There’s a new wave of sound on the horizon carrying with it a broad scope of tantalizing potential applications, including advanced ultrasonic imaging and therapy, and acoustic cloaking, levitation and particle manipulation." https://lnkd.in/eN74kab View in LinkedIn

OTHER APPLICATIONS. "Beyond the challenges posed by optical waves, cloaking has been studied and proposed for sound, mechanical, seismic, and even matter waves. This has been possible because all these phenomena are governed by wave equations, in many ways analogous to the way electromagnetic signals and light propagate." https://lnkd.in/ejq5Tyt View in LinkedIn
