Mineral resources are essential for reaching net-zero ambitions by 2050. There is a rising diversity of metals in electricity generation and storage technologies, as well as for mobility technologies. However, little is known about the future supply of minor elements historically mined in low volumes such as indium, tellurium, germanium, or tantalum.

Article Synopsis
  • Widespread insect losses pose a significant global concern, necessitating an understanding of the drivers behind these declines and the coverage of insects within protected areas.
  • The study utilized extensive insect DNA metabarcoding data from 31,846 flying insect species across Germany to analyze the effects of differing land cover, weather, and protection status on insect biodiversity.
  • Findings revealed that increased land cover heterogeneity leads to higher insect biomass and species richness, particularly in low-vegetation habitats, which, despite their biodiversity, are often under-protected in conservation efforts.

Purpose: To examine the impact of deep learning-augmented contrast enhancement on image quality and diagnostic accuracy of poorly contrasted CT angiography in patients with suspected stroke.

Methods: This retrospective single-centre study included 102 consecutive patients who underwent CT imaging for suspected stroke between 01/2021 and 12/2022, including whole brain volume perfusion CT (VPCT) and, specifically, a poorly contrasted CT angiography (defined as < 350HU in the proximal MCA). CT angiography imaging data was reconstructed using i.

Mitigating ongoing losses of insects and their key functions (e.g. pollination) requires tracking large-scale and long-term community changes.

Although species evolve in response to many intrinsic and extrinsic factors, frequently one factor has a dominating influence on a given organ system. In this context, mouthpart shape and function are thought to correlate strongly with dietary niche and this was advocated for decades, e.g.
