Microplastics are ubiquitous in our oceans, yet we are still clarifying what risks they pose to marine organisms, which can be challenging due to their trait diversity and spatial patchiness. Laboratory-based studies assessing risk demonstrate that many marine animals internalize microplastics, either actively through ingestion or passively via respiration. However,...
A radioactive particulate release experiment to produce a near-field ground deposition representative of small-scale venting from an underground nuclear test was conducted to gather data in support of treaty capability development activities. For this experiment, aCO₂‐driven “air cannon” was used to inject ¹⁴⁰La, a radioisotope of lanthanum with 1.7‐d half-life...
CONTEXT: In older adults with multiple conditions, medications may not impart the same benefits seen in patients who are younger, or without multi-morbidity. Furthermore, medications given for one condition may adversely affect other outcomes. Beta-blocker (β-Blocker) use with coexisting cardiovascular disease (CVD) and chronic obstructive pulmonary disease (COPD) is such...
