Article Synopsis
- The Kunming-Montreal Global Biodiversity Framework was created after global biodiversity declines were not halted by 2020, aiming for societies to live in harmony with nature by 2050.
- It includes mechanisms for transparency and responsibility, featuring a detailed Monitoring Framework with indicators to track progress at both national and global levels.
- While many indicators are ready for use, challenges like data availability and methodology require investment and collaboration between Parties and the scientific community to improve biodiversity measurement and action.
Metabolic rate, the rate of energy use, underpins key ecological traits of organisms, from development and locomotion to interaction rates between individuals. In a warming world, the temperature-dependence of metabolic rate is anticipated to shift predator-prey dynamics. Yet, there is little real-world evidence on the effects of warming on trophic interactions.

We highlight the recent developments in the porting to GPUs of the main codes, using an approach based on OpenACC and CUDA Fortran offloading. We describe, in particular, the results achieved on linear-response codes, which are one of the distinctive features of the Quantum ESPRESSO suite.

As input, yambo requires ground state electronic structure data as computed by density functional theory codes such as Quantum ESPRESSO and Abinit. yambo's capabilities include the calculation of linear response quantities (both independent-particle and including electron-hole interactions), quasi-particle corrections based on the GW formalism, optical absorption, and other spectroscopic quantities.

- The study simulates the formation of ordered amyloid-like beta structures using 18 polyvaline chains in a solvent, employing molecular dynamics and bias-exchange metadynamics to explore different structures.
- The researchers analyzed hundreds of possible configurations focusing on varying parallel and antiparallel β-sheets to understand the free energy landscapes and the nucleation process.
- The findings indicate that amyloid fibril formation begins with the creation of an antiparallel β-sheet nucleus, later followed by the emergence of parallel sheets, illustrating a complex nucleation pathway that can't be simplified to a single reaction coordinate as per classical nucleation theory.
