Survival of a Long‐Lived Avian Scavenger: Implications of Age, Season, and Landscape Composition for Mortality Risk

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
The goal of this study was to evaluate survival and mortality risk in black vultures (Coragyps atratus), a protected native species of conflict management concern in the United States. High survival rates from this study help explain this species' population growth and range expansion and further inform allowable take for sustainable management ...

Autonomous Planetary Rover Navigation and Crater‐Based Map Augmentation for Path Planning and Rock Localization Using Space ROS

open access: yesEngineering Reports, Volume 8, Issue 3, March 2026.
Autonomous planetary rovers operate in GPS‐denied, low‐texture, crater‐rich environments where traditional SLAM‐based navigation systems suffer from localization drift and unreliable obstacle handling. To address these challenges, this work proposes a Space‐ROS–based autonomous navigation framework integrating ROS2 with the NAV2 stack, RTAB‐Map visual ...

Quantifying the Relative Impact of Atmospheric Variables and Polynya Dynamics on Fast Ice in Terra Nova Bay, Antarctica

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Antarctic fast ice in Terra Nova Bay is crucial for regional climate, ecosystems, and scientific logistics but has recently shown unprecedented decline, impacting operations at Jang Bogo Station. Despite its significance, there remains limited predictive understanding of Antarctic fast ice dynamics, especially regarding thickness and stability, with ...

Reinforcement Learning Enabled Nanophotonic Devices

open access: yesLaser &Photonics Reviews, Volume 20, Issue 6, 18 March 2026.
A reinforcement learning algorithm is used to design photonic devices. The method creates metagratings and grating couplers that efficiently control both the direction and polarization of light. Further, a reinforcement learning approach is used to design in‐plane integrated photonic devices. This approach paves the way for advanced photonic components
