Warmer spots within fields have more blooms and more bees

Climate can vary across large areas of land, but it also can vary within much smaller areas such as farms. A new study by researchers at Penn State examined whether these microclimates — the climate of a very small or restricted area — affect pollination by both wild and managed bees and resulting wild blueberry yields.

How a genetic tug-of-war decides the fate of a honey bee

Despite having identical genetic instructions, female honey bee larvae can develop into either long-lived reproductive queens or short-lived sterile workers who help rear their sisters rather than laying their own eggs. Now, an interdisciplinary team led by researchers at Penn State has uncovered the molecular mechanisms that control how the conflict between genes inherited from the father and the mother determine the larva’s fate.

The arc of health frameworks grew over time from one that siloed human, agricultural and environmental ecosystems from each other to a One Health structure that focused on pathogen spillovers shaping the risk of disease across ecosystems. An expanded vision of One Health microbiome sciences from Penn State incorporates the ecology of all microbes. It emphasizes that the flow of both disease-causing and health-promoting microbes links humans, environment and agriculture together to shape the sustainability of ecosystem wellness and resilience. This One Health framework intentionally unifies the microbiome sciences to advance core disciplinary theories and principles with cross-system validation and comparative studies, according to the researchers.

Q&A: Unifying the microbiome sciences for global health and sustainability

Recently, members of Penn State's One Health Microbiome Center published an article in the American Society for Microbiology’s flagship journal, mBio. In this Q&A, a few of the paper’s authors discussed how the center is leading the charge to breakdown traditional disciplinary silos and expand the One Health focus to include more than just pathogenic microbial threats.
