QUNTUM METAMATERIALS. "Another type uses periodically arranged cold atom cells, accomplished with ultra-cold gasses. A photonic bandgap can be demonstrated with this structure, along with tunability and control as a quantum system." Photonic band gap sounds familiar? (Photonic crystals). https://lnkd.in/ebeJXMn View in LinkedIn

ROOT SYSTEM HABITAT. "The rhizosphere provides an especially rich palette for colonization by beneficial (associative and symbiotic) microorganisms, which raises the question as to how roots can distinguish such ‘friends’ from possible ‘foes’ (i.e., pathogens)." https://lnkd.in/eqtV_bF View in LinkedIn

QUANTUM DOTS. "Nanowires can use quantum dots as the unit cells or artificial atoms of the structure, arranged as periodic nanostructures. This material demonstrates a negative index of refraction and effective magnetism and is simple to build. The radiated wavelength of interest is much larger than the constituent diameter." https://lnkd.in/ebeJXMn View in LinkedIn

PLANT DEFENSES. "At the cellular level, the awareness of external threats and the efficient integration of such information for an appropriate response often require robust and adaptable molecular systems." https://lnkd.in/eRdhX_N View in LinkedIn

"QUANTUM metamaterials extend the science of metamaterials to the quantum level. They can control electromagnetic radiation by applying the rules of quantum mechanics...Its behaviour reflects the existence of both EM waves and matter waves." https://lnkd.in/ebeJXMn View in LinkedIn

FRAGMENT IN NATURE. In the case of plants, the root system is particularly challenged to discriminate between friend and foe, because as we will see next weekend, the roots form deep symbiotic relations with helpful microorganisms. View in LinkedIn

FRAGMENT IN NATURE this weekend deals with the remarkable subject of plant innate immunity. This ancient biochemical defense against pathogens is a highly conserved system shared across many kingdoms of creatures. View in LinkedIn

THIS WEEKEND the topic will be how plant roots can tell friend from foe. The foes want to devour them, and the friends want to live with them. We marvel at our almost infinitely capable immune system. Well, no surprise, plants have sophisticated immune systems also, just very different from ours. View in LinkedIn

NEW FIELDS. "The field of metamaterials started with the search for negative dielectric permittivity and magnetic permeability however the range of electromagnetic responses achievable using nanostructured media far surpass the concept of negative index." Starts here on Monday. https://lnkd.in/ePrzn3K View in LinkedIn

LEADING LIGHT. "Metamaterials research has captured the imagination of optical engineers and materials scientists because of their varied applications including imaging, cloaking, sensing, waveguiding, and simulating space-time phenomena." https://lnkd.in/ePrzn3K View in LinkedIn
