What if the brain evolved to serve the gut? Scientists at Flinders University are challenging a cornerstone of biology, arguing that the gut's nervous system may be the body's original "brain," with the brain evolving later to support its needs.
A joint research team from Saitama University, Tottori University, the National Institute of Genetics, the National Institute for Basic Biology, and the Exploratory Research Center on Life and Living Systems has identified an evolutionarily conserved role for Hox9–10 genes in establishing the progenitor cells that give rise to vertebrate hind appendages. Using genetic analyses in zebrafish and CRISPR-Cas9 experiments in the Iberian ribbed newt, the team showed that these genes act at an unexpectedly early stage of pelvic fin and hindlimb development, providing new insight into how the vertebrate paired appendage-patterning system may have evolved.
The winners of the Applied Microbiology International Horizon Awards 2026 have been announced.
The prizes, awarded by the learned society Applied Microbiology International (AMI), celebrate the brightest minds in the field and promote the research, group, projects, products and individuals who continue to help shape the future of applied microbiology.
A new NSF-supported initiative will bring professional development and evidence-based teaching practices to faculty across SUNY, helping expand student success and retention in STEM fields. As part of a $2 million statewide collaboration, the project will provide training in learner-centered instruction, undergraduate research, AI-enabled teaching tools, and faculty mentoring networks. The effort aims to accelerate the adoption of proven teaching methods across SUNY and strengthen New York’s future STEM workforce.
A protein complex that normally puts the brakes on genes may also be crucial for reproduction in plants, according to new research published in Science Advances. In thale cress, DREAM appears to switch on genes during meiosis that are important for the exchange of genetic material. But when the complex is missing, reproductive development becomes defective and fertility is severely reduced.
