Article Synopsis
- Jumping is a vital locomotion method for insects, especially in the Orthoptera group, serving purposes like travel and predator evasion.
- This study focuses on a predatory bush cricket that uses visual cues to adjust its jumping behavior for navigating complex environments.
- The research reveals that the cricket can control its take-off speed and rotation rate based on the target distance, demonstrating distinct adjustments in jumping kinematics and body posture for different jump heights.

Article Abstract
Jumping is one of the most used forms of locomotion by insects, and a characteristic trait of the Orthoptera (locusts, crickets, and allies). Their specialized jumping behaviors have evolved for various functions, including travel, predator evasion, and flight initiation. While these jumping behaviors have been studied, targeted jumps required for navigating complex environments and hunting have received little attention. Here, we document a vertical jumping behavior in a species of neotropical predatory bush cricket (. Tettigoniidae: Meconematinae), which uses visual cues to estimate target distance. Jumping kinematics were adjusted between jump heights (50mm, 75mm, and 100mm), with an increase in linear velocity and decrease in angular velocity at higher target heights. Body and leg postures also varied between jump heights. This study provides evidence that can independently control both the speed at take-off and rotation rate based on target distance to achieve a precise and controlled landing.

Purpose: Despite its importance, little is known about the patterns and predictors of Survivorship Clinic attendance in head and neck cancer (HNC). We sought to determine the cumulative incidence of Survivorship Clinic attendance stratified by demographic, clinical, and socioeconomic factors, and to identify factors independently associated with attendance.
Methods: Our analysis population consisted of 2,252 patients diagnosed with primary HNC and seen at our institution's HNC Survivorship Clinic after completing treatment from 2016-2021.

Glutamine: fructose-6-phosphate aminotransferase (GFAT) is the first rate-limiting enzyme in the hexosamine biosynthetic pathway, which plays a crucial role in various biological processes, including chitin metabolism in insects. Locusta migratoria, a widespread and highly destructive agricultural pest, poses a significant threat due to its rapid reproduction and long-distance migration. In this study, we identified and characterized LmGFAT as a key regulator of locust development.

Pyroelectrodynamic therapy (PEDT) of tumors faces challenges due to its low electrocatalytic efficiency at mild temperature and the potential for off-target toxicity to healthy tissue. To overcome these issues, we have engineered pyroelectric nanoparticles (NPs) that feature a pH-triggered heterojunction structure and tumor-selective reactive oxidative species (ROS) production, faclitating synergistic PEDT and mild photothermal therapy (PTT). Herein, molybdenum trioxide (MoO) was deposited in-situ on the surface of tetragonal BaTiO (tBT) to create tBT@MO.

Permafrost degradation is accelerating across the Arctic, posing growing risks to cultural heritage (CH) sites. This study presents the first archipelago-scale hazard assessment of CH to retrogressive thaw slumps (RTS) and thermo-erosion gullies (TEG) in Svalbard, one of the fastest-warming regions globally. By overlaying recent RTS and TEG inventories with the spatial distribution of protected CH sites, we quantify hazard exposure for 55.
