A Breath of Fresh Air: A Novel Passive Airborne eDNA Approach for Scalable Terrestrial Biodiversity Monitoring

Ecology and Evolution, Volume 16, Issue 4, April 2026.
The study introduces the Nutshell eDNA sampler, an inexpensive, reusable passive device for collecting environmental DNA from air to monitor terrestrial biodiversity. Tested at the Rotterdam Zoo, it detected numerous species and complimented active samplers in identifying zoo animals, continuing to accumulate DNA over longer sampling times and ...

HBAC: Hierarchical‐Based Access Control Model for Storage Management in Data Lake Environments

Software: Practice and Experience, Volume 56, Issue 4, Page 445-461, April 2026.
ABSTRACT Background Traditional storage systems typically use simple access control models that manage permissions at the user or group level. These models, however, are not well suited for data lake environments, where large‐scale and diverse datasets must be accessed concurrently by users across multiple hierarchical levels, and they also have many ...

Dual‐scale drivers of soil biodiversity in agroecosystems: Field management outweighs landscape effects, but both matter

Journal of Applied Ecology, Volume 63, Issue 2, February 2026.
These findings highlight the need for conservation strategies that integrate both field‐scale and landscape‐scale planning. The promotion of diverse land use types might offer a practical pathway to maximize the effectiveness of soil biodiversity conservation within an intensively managed agricultural matrix.

Sustainable Control of Carbon Emissions and Energy Consumption Through a Green Data Center Approach

The Scientific World Journal, Volume 2026, Issue 1, 2026.
Data center management, the foundation of contemporary cloud computing, has made energy saving a top priority. Among other difficulties, the placement of virtual machines (VMs) has a major impact on data center resource and energy usage. Assigning VMs to physical machines (PMs) is a challenging NP‐hard problem, especially in large‐scale infrastructures
