Researchers at Kumamoto University have developed a new rum using the rare fission yeast Schizosaccharomyces japonicusponicus, producing fruity esters and complex aromas. The resulting 'JAPONICUS RHUM AGRICOLE' offers layered flavors reminiscent of ripe banana and apple.
A recent study has confirmed that wild African chimpanzees consume significant quantities of alcohol, with 17 out of 20 urine samples containing ethyl glucuronide, a metabolic byproduct of ethanol. The chimps' diet likely consists of fermented fruits, which provide around 14 grams of ethanol per day.
Researchers developed DeMemSeg, an AI-driven pipeline that accurately segments overlapping membrane structures with accuracy comparable to expert manual analysis. The approach enables large-scale, objective, and quantitative analysis of morphological data, providing a foundational technology for advancing disease mechanisms.

This discovery has implications for understanding basic life processes and diseases caused by disruptions in endocytosis.
A new study describes an engineered approach that makes protein aggregates amenable to spatial manipulations in both budding yeast and human cells. This system allows for the export of protein aggregates from cells, potentially protecting mother cells from toxicity and contributing to a better understanding of neurodegenerative diseases.
Researchers developed an automated spot assay system using a liquid-dispensing robot to evaluate yeast growth potential on agar media. The new system, which corrects variations in agar height and automatically observes and quantifies yeast growth, showed comparable accuracy to manual experiments.
Researchers discovered how yeast cells transform their cytoplasmic biophysical properties to return to vegetative growth. The study sheds light on the mechanisms behind spore dormancy and its exit.
Researchers at NIH's National Human Genome Research Institute identified a gene, KTD1, that provides resistance to the K28 toxin in yeast. This discovery sheds light on the molecular mechanisms underlying toxin resistance and has implications for understanding human toxin resistance.
Researchers discovered a smart molecular glue formed by proteins clinging to microtubules, enabling nucleus positioning during cell division. The 'glue' enables mechanical forces to be transduced as desired, with flexible properties allowing it to withstand tension.
Scientists have developed a method to produce strigolactones, a group of plant hormones that prevent excessive budding and branching. By combining yeast and bacteria, researchers can synthesize these hormones from microbes, providing a promising alternative to traditional methods.
Scientists discovered a lineage of budding yeasts that has lost dozens of genes involved in DNA repair and cell cycle processes. These gene losses result in the yeast's genomes changing rapidly, leading to unique biological characteristics.
A team of evolutionary biologists reconstructed the genomic and metabolic characteristics of a 400-million-year-old common ancestor of more than 1,000 budding yeast species. This ancestor was metabolically diverse, able to live on a third more food sources than modern counterparts.
Researchers sequenced and compared the genomes of 332 yeast species, revealing an extensive picture of their evolution over hundreds of millions of years. The study suggests that yeasts evolved through reductive evolution, losing traits to specialize in specific food sources, with modern yeasts having narrower appetites.
