Excessive copper (Cu) absorption in calves may increase the risk of excessive hepatic Cu accumulation, likely driven by their elevated pre-ruminant absorptive capacity, with the potential for harmful Cu accumulation leading to adverse health and productivity outcomes. However, quantitative data across the weaning transition remains limited. This study utilized secondary data and bio-banked samples from 35 Holstein–Friesian bul...

Cancer remains a significant public health challenge that requires a multidisciplinary workforce equipped with strong cancer research skills and clinical insight. Over the past decade, the University of Louisville’s Cancer Education Program was developed to enhance career trajectories in oncology through a mentored cancer research experience for both professional and college students. In a structured 10-week program, trainees...

Sea otters ( Enhydra lutris ) exhibit morphological and physiological adaptations supporting a mass‐specific resting metabolic rate (RMR) 2.9‐fold higher than predicted for terrestrial mammals of similar size. Their elevated metabolism results primarily from thermogenic mitochondrial proton leak to compensate for heat loss in the marine environment because of their high surface‐area‐to‐volume ratio, combined with their relianc...

In August 2024, a northern fur seal mortality event was observed on St. Paul Island, AK in the southeast (SE) Bering Sea. Ten seals in good body condition were found dead along with large accumulations of dead fish on Benson Beach located on St. Paul Island. Full necropsies of the five available adult seals, one pup, and several fish did not reveal any overt causes of death. Testing of tissues for the algal neurotoxins domoic...

The scientific aspiration of building causal knowledge has received little explicit discussion in ecology despite its fundamental importance. When methods are described as ‘causal’, emphasis is increasingly placed on statistical techniques for isolating associations so as to quantify causal effects. In contrast, natural scientists have historically approached the pursuit of causal knowledge through the investigation of mechani...
