THE JUICE. "In the past decade, the exploration for topological invariants is substantively followed up in different subfields of physics, making a paradigm shift for topological states, from electronics to photonics, phononics as well as mechanics. We have theoretically proposed and experimentally demonstrated the acoustic topological insulator." https://lnkd.in/eVVrjPr 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

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

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

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

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

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

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

PLANT PERCEPTION. "To defend themselves against potential pathogenic microbes or pests, plants rely only on innate immunity and lack specialized immune cells. Plant innate immunity employs a two-tier perception system." https://lnkd.in/eRdhX_N View in LinkedIn

PLANT PERCEPTION. "The first layer is mediated by surface-localized pattern recognition receptors (PRRs) leading to PRR-triggered immunity (PTI). The second layer involves intracellular immune receptors." https://lnkd.in/eRdhX_N View in LinkedIn
