Rapid land use changes across the Southeast United States are creating challenges for young and beginning farmers, family farm operations and the economies of rural communities.

To address this challenge, the University of Tennessee Institute of Agriculture (UTIA) and the Tennessee Farm Bureau Federation will host the inaugural Southeast Farm and Forest Land Summit on Monday, October 12, 2026, at the Tennessee Farm Bureau headquarters in Columbia, Tennessee.

Paraxial optical skyrmions, defined by Stokes vectors, have attracted significant attention due to their ability to propagate in free space with preserved topological structures. Recently, this exotic topological structured light has been extended to the spatiotemporal domain, though so far only in the visible and near-infrared regimes. The team led by Academician Zhuang Songlin and Professor Yi Liu at the University of Shanghai for Science and Technology theoretically explores, for the first time, the generation and control mechanisms of extreme-ultraviolet spatiotemporal skyrmions based on the high-harmonic generation process. The discovery is published in the journal PhotoniX.

Researchers from the University of Science and Technology of China proposed and numerically demonstrated a scheme to realize the self-healing effect of non-Hermitian skin modes in photonic Floquet lattices. They introduced the concept of skin mode tunability (SMT), a mechanism in which the spectrum of skin modes localized at one boundary can be tuned via a potential applied at the opposite boundary. Using a tight-binding Floquet Hamiltonian and the beam propagation method (BPM) simulation in coupled helical waveguides with experimentally accessible parameters, the researchers showed that a targeted skin mode can be spectrally isolated and transformed into a self-healing state that recovers its profile after encountering a disturbance. The study provides a general framework for engineering skin modes through local perturbations and for controlling wave dynamics in non-Hermitian photonic systems.
