Schoolchildren flee as canopy collapses during deadly Philippines quake Copy/paste the link below: Copy/paste the article video embed link below: Updated: Children scream and run for cover as a school canopy collapses during the powerful earthquake that hit the southern Philippines, killing at least four people and injuring more than 200.
Repeatability and Heritability of UAV-Derived Canopy Traits in a Cassava Breeding Population Using Time-Series Data from Two Consecutive Growing Seasons
Cassava is a major staple crop in tropical regions, particularly in Sub-Saharan Africa, yet its productivity remains constrained by genetic and agronomic limitations. A major bottleneck in cassava breeding is the difficulty of accurately phenotyping agronomic traits under field conditions using conventional, labor-intensive methods. Here, we evaluated the potential of uncrewed aerial vehicle (UAV)-based phenotyping to quantify canopy growth traits and assess their genetic relevance under...
Illumination-Invariant Anomaly Detection for Sub-Canopy UAV Multispectral Point Clouds
Announce Type: new Abstract: Unmanned Aerial Vehicle (UAV) multispectral point clouds (MPC) provide high-dimensional spatial-spectral data for sub-canopy target detection; however, their efficacy is significantly compromised by severe illumination heterogeneity caused by vegetation shadows. To address this, we propose a prior-free anomaly detection framework capable of robustly handling lighting variations. First, we formulate solar angle estimation as an inverse optimization problem.
‘Osprey cam’ streams life of nesting seabirds perched at tip of 55 metre-long Queensland rainforest canopy crane
Researchers believe the same pair of birds have been mating and nesting in the unusual spot in the Daintree Rainforest for 15 consecutive yearsGet our breaking news email, free app or daily news podcastIt started by chance – but it should have come as no surprise that two ospreys would pick a hi-tech research facility to make their home. James Cook University’s 47-metre tall crane towers over the far-north Queensland rainforest canopy, making it the perfect nesting place for the seabird.
Directional effects on urban-canopy drag
Announce Type: new Abstract: Understanding the influence of wind direction on building drag is essential for predicting urban climate and assessing wind loads in complex urban environments. This study investigates the wind-directional dependence of building drag over the University of Bristol campus, comprising 110 buildings of diverse shapes and heights, using 24 building-resolved large-eddy simulations under a constant imposed pressure gradient.
Fine-Tuning Improves Information Conveyance in Language Models
arXiv:2605.30844v1 Announce Type: new Abstract: Fine-tuning is often believed to reduce uncertainty and diversity in large language models, but existing analyses overlook output length, a key confounder, and therefore fail to capture how uncertainty is distributed across an entire generation rollout. To address this, we propose Canopy Entropy ($\mathrm{CE}^\star$), a measure that views language generation from a tree perspective, where ``canopy'' represents the space of all possible...
ForestMamba: Sparse Mamba with Geometry-guided Queries for 3D Forest Point Cloud Segmentation
arXiv:2606.01549v1 Announce Type: new Abstract: AI-based semantic and instance segmentation of terrestrial and drone LiDAR point clouds is emerging as a transformative approach for converting the complex 3D structure of forests into actionable information for forest monitoring and biodiversity assessment. However, forest LiDAR scenes remain highly challenging due to their large data volumes, irregular sampling density, overlapping and complex canopy structure, and geographic variability....
NASA develops sensor to improve firefighter safety
With peak wildfire season approaching, scientists with NASA's FireSense project have created low-cost thermal sensors to install on fire bulldozers that will alert firefighters when heat from a nearby fire reaches a dangerous level. The sensors also provide researchers with important data on what happens beneath the canopy during a fire.
Biomazon: A Multimodal Dataset for 3D Forest Structure and Biomass Modeling in the Amazon Basin
Announce Type: new Abstract: Accurate, spatially explicit characterization of tropical forest structure is essential for carbon accounting and ecosystem monitoring, yet most ML pipelines predict canopy-top height proxies (e.g., RH95/RH98) or AGBD as separate scalar targets, rather than learning the forest vertical structure as an ordered profile. The community lacks a ML-ready multimodal benchmark for predicting the entire GEDI RH profile jointly with AGBD, or for evaluating methods that...
