A recurrent neural circuit in Drosophila temporally sharpens visual inputs.

A critical goal of vision is to detect changes in light intensity, even when these changes are blurred by the spatial resolution of the eye and the motion of the animal. Here, we describe a recurrent neural circuit in Drosophila that compensates for blur and thereby selectively enhances the perceived contrast of moving edges. Using in vivo, two-photon voltage imaging, we measured the temporal response properties of L1 and L2, two cell types that receive direct synaptic input from photoreceptors.

This article presents a comprehensive dataset developed for benchmarking machine learning-based landslide susceptibility models. The dataset includes landslide polygons delineated through manual interpretation of high-resolution satellite imagery and controlling factors data extracted from topographic maps and Indonesia's national digital elevation model (DEMNAS). Landslide events were mapped by comparing pre- and post-event satellite imagery from Tropical Cyclone (TC) Cempaka, which occurred from 27 to 29 November 2017, and verified through field surveys.

Article Synopsis
- High-resolution NMR (nuclear magnetic resonance) spectra are essential for studying the structure and shape of organic molecules, especially those with labile protons.
- Ma et al. (2024) showed that using 2,2,2-trifluoroacetic acid (TFA) in high concentrations improves NMR signal clarity for nitrogen-containing compounds that undergo structural changes.
- This commentary reviews previous studies and discusses the potential of TFA to enhance NMR resolution for various organic functional groups, even at lower acid-to-solute ratios, and suggests pathways for clearer structural analysis using these labile protons.

The visual system compensates for differences between peripheral and foveal vision using different mechanisms. Although peripheral vision is characterized by higher spatial uncertainty and lower resolution than foveal vision, observers reported objects to be less distorted and less blurry in the periphery than the fovea in a visual matching task during fixation (Valsecchi et al., 2018).

Understanding surface collective dynamics in quantum materials is crucial for advancing quantum technologies. For example, surface phonon modes in quantum paraelectrics are thought to be essential in facilitating interfacial superconductivity. However, detecting these modes, especially below 1 terahertz, is challenging because of limited sampling volumes and the need for high spectroscopic resolution.
