A new study from Lund University in Sweden shows that migratory birds fly at peak efficiency at a medium pace – precisely the speed they use during their long journeys across the continents.

Researchers from The University of Osaka found that the radial spoke protein CFAP91 is crucial for flagellum formation in sperm, and that the proximal protein EFCAB5 is important for sperm motility. Loss of function of either of these proteins impairs spermatogenesis, suggesting that their mutation or loss can lead to male infertility.

POSTECH team synthesizes octahedral Prussian Blue using glycerol, boosting hybrid capacitor performance.

Artificial intelligence is now better than humans at identifying many patterns, but evolutionary relationships have always been difficult for it. A team from the Bioinformatics Department at Ruhr University Bochum, Germany, working under Professor Axel Mosig has trained a neuronal network to tackle this issue. The AI can relate any data from different species in an evolutionary relationship and identify which characteristics have developed in what manner throughout the course of evolution. “Our approach lets artificial intelligence look at data through the lense of evolution, in a way,” explains Vivian Brandenburg, lead author of the report published in Computational and Structural Biotechnology Journal on August 22, 2025.
