Beach litter sources around Nuuk, Greenland: An analysis by UArctic summer school graduate course students.

Modeling studies illustrate the potential for long-range transport of plastics into the Arctic, although the degree to which this occurs remains relatively undocumented. We utilised a teaching exercise at a UArctic summer school graduate course in Nuuk, Greenland to conduct a preliminary in-depth analysis of beach litter sources in the Nuup Kangerlua fjord. Students and instructors collected and analysed 1800 litter items weighing 200 kg from one location in the fjord and another at its mouth.

Lessons Learned in Developing Virtual Neuroscience Labs.

The global COVID-19 pandemic has had a major impact on teaching approaches across higher education institutions. In this article, we reflect on the lessons learned designing and developing two virtual neuroscience labs and how they can positively contribute to Neuroscience teaching beyond this pandemic.

An ideal solution? Optimising pretreatment methods for artificially mummified ancient Egyptian tissues.

Rationale: Although the analysis of skeletal remains dominates the study of ancient dietary stable isotopes, mummified bodies also allow short-term diet to be studied through the analysis of soft tissues. The application of resins, waxes and oils during mummification can affect the results obtained. This study assesses a range of methods for removing such substances from mummified tissue.

Variations in immunohistochemical preservation of proteins in a mummification model.

Immunohistochemistry is an important tool in the investigation of ancient mummified remains because of its ability not only to detect proteins but also to isolate their location to specific tissues and thereby improve confidence that the results are genuine. A mouse model of Egyptian mummification has been used to demonstrate that the survival of proteins, judged by the retention of immunohistochemical staining, varies markedly. Some survive the process well, whereas others become barely detectable despite the morphology of the tissue being excellently preserved.
