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

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

FUNDAMENTAL FINDING. "Time reversal (T) invariant topological insulator is widely recognized as one of the fundamental discoveries in condensed matter physics. Recently, it has created a paradigm shift for topological insulators, from electronics to photonics, phononics as well as mechanics, bringing about not only involved new physics but also potential applications in robust wave transport." https://lnkd.in/eVVrjPr View in LinkedIn

PARADIGM SHIFT. "This demonstration brings a paradigm shift in the field of metamaterials similar to developments that led to dramatic advances in silicon technology." After 50 years of research, this group achieved atomic-scale metal-superlattice crystals with clouds of electrons called surface plasmons to manipulate and control light. https://lnkd.in/ezhDu_8 View in LinkedIn

WAVE CONTROL IS CENTRAL. "Hyperbolic metamaterials are a multi-functional platform to realize waveguiding, imaging, sensing, quantum and thermal engineering beyond conventional devices. This metamaterial uses the concept of engineering the basic dispersion relation of waves to provide unique electromagnetic modes that can have a broad range of applications." https://lnkd.in/ePrzn3K View in LinkedIn

"HYPERBOLIC METAMATERIALS could bring optical advances including powerful microscopes, quantum computers and high-performance solar cells. The material has been shown to work in a broad spectrum from near-infrared to visible light, potentially promising a wide array of applications." 2014). https://lnkd.in/ezhDu_8 View in LinkedIn

HYPERBOLIC METAMATERIALS. "We review the fundamental properties of metamaterials with hyperbolic dispersion and present the various applications where such media offer potential for transformative impact. These artificial materials support unique bulk electromagnetic states which can tailor light-matter interaction at the nanoscale." https://lnkd.in/ePrzn3K View in LinkedIn
