A team led by researchers from the University of Osaka has revealed the first structure of an umami taste receptor. They found that the pufferfish receptor can sense many more amino acids than the human receptor, including some linked to flavors humans detect as sweet. This helps the fish to detect more types of savory chemicals in their food. The research also shows how the receptor’s structure makes this flexibility possible. The findings could help develop new umami flavors.

In a study of parakeets, researchers with the University of Cincinnati and Duke University found that sex doesn't decide who initiates fights, who is targeted or who rises in the dominance hierarchy.

Published in the International Journal of Extreme Manufacturing, researchers improved the balance of strength and ductility by using laser powder bed fusion to create alternating coarse- and fine-grained regions in a zinc–copper alloy.

Fungi represent a cornerstone of industrial biotechnology, serving as indispensable platforms for the production of enzymes, organic acids, and high-value pharmaceuticals. In the era of synthetic biology and green manufacturing, the engineering of fungal cell factories offers unparalleled opportunities to address global challenges in sustainability, human health, and the circular bioeconomy. This article collection aims to capture the cutting-edge advances in fungal biomanufacturing, ranging from foundational metabolic engineering to the development of robust industrial strains.

Filamentous fungi and yeasts are powerful platforms for sustainable chemical production. As industries shift away from petrochemical-based processes, engineered fungal cell factories offer a renewable route to high-value compounds—from therapeutic alkaloids to biodegradable polymers. By integrating cutting-edge tools like CRISPR-Cas9, biosensors, and dynamic pathway regulation, we can overcome long-standing bottlenecks in titer, rate, and yield. Furthermore, linking fungal biomanufacturing with medicinal plant biomass valorization directly supports the circular bioeconomy, reduces agricultural waste, and enables the sustainable production of bioactive natural products that are otherwise difficult to source.

This collection will serve as a platform for presenting innovative strategies that bridge the gap between laboratory-scale design and industrial-scale application, emphasizing the critical role of fungi in shaping a sustainable manufacturing future. We invite contributions that explore the full spectrum of fungal biotechnology, with a focus on leveraging the unique metabolic versatility of yeast and filamentous fungi. Topics of interest include the design and optimization of fungal cell factories for the sustainable production of biofuels, biopolymers, and high-value natural products. We particularly welcome studies that integrate systems biology, CRISPR-based genome editing, and process engineering to overcome current bottlenecks in titers, yields, and rate of products. Additionally, given the growing significance of traditional medicine and functional foods, this issue will highlight the role of fungal systems in the herb bioprocessing to produce bioactive compounds.
