Representing colours

How to describe the faded colours in ancient textiles in a way that is understandable to others when no laboratory facilities are available and dye analysis not possible? How do we find names of colours that carry the right connotations to an international readership, and how can we refer to them? The paper discusses challenges posed by these questions and how they have been attempted solved in the Mons Claudianus textile project

The Archaeology of Textiles – Recent advances and new methods

Arheologija tekstila doživljava nagli razvoj posljednjih godina. U članku se predstavlja pregled dosadašnjih saznanja o prapovijesnom europskom tekstilu, prikazuju se recentna dostignuća u metodama analize, kao što su analiza vlakana i boja, datiranje radioaktivnim ugljikom te analiza izotopa stroncija koja bi mogla pridonijeti određivanju podrijetla tekstilnih vlakana kao što su vuna, lan ili kopriva. Raspravlja se i o eksperimentalnoj arheologiji kao metodi proučavanja tekstila.Archaeology of textiles has seen rapid development in recent years. The paper presents an overview of current knowledge on prehistoric textiles from Europe, surveying recent advances in methods of analysis such as fibre and dyes analysis, radiocarbon dating, and strontium isotope analysis that is promising to allow provenancing of textile fibres such as wool, fax or nettle. Experimental archaeology as a tool in textile studies will also be discussed

En glemt skat: Miranda Bødtkers tegninger af arkæologiske tekstiler

Over many years, illustrator Miranda Bødtker (1896–1996) carried out drawings for botanists, zoologists and archaeologists at Bergen Museum, the University of Bergen. After her death, thousands of drawings were discovered in her estate. Among them were numerous unpublished drawings of archaeological textiles from five sites. Bødtker’s illustrations show that although several scholars have studied the textiles, none had seen them all. This applies in particular to textiles from two Viking Age burials, Grønhaug and Dale, both of which comprise remains of figured tapestries that are hardly mentioned in archaeological literature. Grønhaug, and a boat from Halsnøy also offer several types of textiles related to the maritime world. The paper presents Bødtker’s drawings and discusses how they compare with published descriptions of those textiles, with drawings of textiles from the Oseberg burial, and to what degree this form of documentation meets current scientific demands.publishedVersio

Control of intestinal stem cell function and proliferation by mitochondrial pyruvate metabolism.

Most differentiated cells convert glucose to pyruvate in the cytosol through glycolysis, followed by pyruvate oxidation in the mitochondria. These processes are linked by the mitochondrial pyruvate carrier (MPC), which is required for efficient mitochondrial pyruvate uptake. In contrast, proliferative cells, including many cancer and stem cells, perform glycolysis robustly but limit fractional mitochondrial pyruvate oxidation. We sought to understand the role this transition from glycolysis to pyruvate oxidation plays in stem cell maintenance and differentiation. Loss of the MPC in Lgr5-EGFP-positive stem cells, or treatment of intestinal organoids with an MPC inhibitor, increases proliferation and expands the stem cell compartment. Similarly, genetic deletion of the MPC in Drosophila intestinal stem cells also increases proliferation, whereas MPC overexpression suppresses stem cell proliferation. These data demonstrate that limiting mitochondrial pyruvate metabolism is necessary and sufficient to maintain the proliferation of intestinal stem cells
