Agricultural researchers are increasingly encouraged to engage with stakeholders to improve the usefulness of their projects, but iterative research on the design and assessment of stakeholder engagement is scarce. The USDA Long-Term Agroecosystem Research (LTAR) Network recognizes the importance of effective engagement in increasing the utility of information and technologies for future agriculture. Diverse stakeholders and researchers at the Kellogg Biological Station (KBS) LTAR site co-designed the KBS LTAR Aspirational Cropping System Experiment, a process that provides a testing ground and interdisciplinary collaborations to develop theory-driven assessment protocols for continuous stakeholder engagement.

Obesity plays a crucial role in the development and progression of type 2 diabetes mellitus (T2DM) by causing excessive release of free fatty acid from adipose tissue, which in turn leads to systemic infiltration of macrophages. In individuals with T2DM, the infiltration of macrophages into pancreatic islets results in islet inflammation that impairs beta cell function, as evidenced by increased apoptosis and decreased glucose-stimulated insulin secretion. The present study aimed to investigate the effects of non-lethal sonodynamic therapy (NL-SDT) on bone marrow-derived macrophages (BMDMs) exposed to high glucose and palmitic acid (HG/PA).

Article Synopsis
  • Penthiopyrad, a chiral pesticide, demonstrates significant differences in bioactivity and biotoxicity, with S-penthiopyrad being much more potent and persistent than R-penthiopyrad against soil pathogens.
  • S-penthiopyrad not only outperformed R-penthiopyrad in efficacy but also caused greater bioaccumulation and induced more severe responses in non-target organisms like earthworms.
  • The varied interactions of the two enantiomers with soil proteins and detoxifying enzymes are key to their differing impacts, suggesting S-penthiopyrad has more promise for agricultural applications.

Article Synopsis
  • Eutrophication, caused by too much phosphorus in lakes, leads to more organic carbon, but makes it hard to predict how much carbon can be buried in the future.
  • The study checks if phosphorus in lake sediments can show how productive lakes are and defines a way to measure how much carbon lakes can bury based on phosphorus levels.
  • Researchers found that carbon burial potential in Chinese lakes varies by location and has changed over time, with some areas seeing a decrease linked to more farmland nearby.

The directional transformation of carbon dioxide (CO) with renewable hydrogen into specific carbon-heavy products (C) of high value presents a sustainable route for net-zero chemical manufacture. However, it is still challenging to simultaneously achieve high activity and selectivity due to the unbalanced CO hydrogenation and C-C coupling rates on complementary active sites in a bifunctional catalyst, thus causing unexpected secondary reaction. Here we report LaFeO perovskite-mediated directional tandem conversion of CO towards heavy aromatics with high CO conversion (> 60%), exceptional aromatics selectivity among hydrocarbons (> 85%), and no obvious deactivation for 1000 hours.
