Pests or prey? Micromammal species within an ancient anthropic environment at the Norse settlement site of Tuquoy (Westray, Orkney)
Micromammals, like rodents and shrews, adapt rapidly to take advantage of new food sources, habitats and ecological niches, frequently thriving in anthropogenic environments. Their remains, often retrieved during archaeological investigations, can be a valuable source of information about the past environmental conditions as well as interspecies interactions and human activity....Romaniuk, Andrzej A ; Troalen, Lore G ; Bendrey, Robin ; Herman, Jeremy S ; Owen, Olwyn …

Ancient DNA and modelling the Mesolithic-Neolithic transition in Britain and Ireland
The current paradigm-changing ancient DNA revolution is offering unparalleled insights into central problems within archaeology relating to the movement of populations and individuals, patterns of descent, relationships and aspects of identity – at many scales and of many different kinds. The impact of recent ancient DNA results can be seen...Sheridan, J A ; Whittle, Alasdair

The organics revolution: new narratives and how we can achieve them
Organic remains from excavated sites include a wide range of materials, from distinct organisms (‘ecofacts’) to biomolecules. Biomolecules provide a variety of new research avenues, while ecofacts with longer histories of study are now being re-harnessed in unexpected ways. These resources are unlocking research potential, transcending what was previously imagined...Johnston, P ; Booth, T ; Carlin, N ; Cramp, L ; Edwards, B …

Molecular fingerprints resolve affinities of Rhynie chert organic fossils
The affinities of extinct organisms are often difficult to resolve using morphological data alone. Chemical analysis of carbonaceous specimens can complement traditional approaches, but the search for taxon-specific signals in ancient, thermally altered organic matter is challenging and controversial, partly because suitable positive controls are lacking. Here, we show that...Loron , C C ; Rodriguez Dzul, E ; Orr, P J ; Gromov, A V ; Fraser, Nicholas C …

Development and Application of Desorption Electrospray Ionization Mass Spectrometry for Historical Dye Analysis
A desorption electrospray ionization (DESI) source was built and attached to a Bruker 7T SolariX FT-ICR-MS for the in situ analysis of 14 early synthetic dyestuffs. Optimization using silk and wool cloths dyed with rhodamine B concluded that when using a commercial electrospray emitter (part number: 0601815, Bruker Daltonik), a...Sandström, Edith ; Vettorazzo, Chiara ; Mackay, C Logan ; Troalen, Lore G ; Hulme, Alison N

Understanding colour in Renaissance embroidery: new analytical approaches
Historical objects are often a reflection of the time they were created. Depending on the nature of the object, they can give insight into the necessities, fashion trends and mentality of the time they were used. To expand the information received from historic objects, scientific techniques can be applied, which... -

Textiles in a Viking Age hoard: Identifying ephemeral traces of textiles in metal corrosion products
This paper presents a novel method and terminology to identify and describe textiles from ephemeral traces in metal corrosion products. Since the 1980s, mineralised textiles (positive and negative casts in Janaway’s terminology) have been an important source of archaeological evidence. A major issue now is the identification of textiles in...Davis, Mary ; Harris, Susanna

Abstract
Deep Impact: Analyzing a De Havilland Comet’s Historic Paint Layers
A De Havilland Comet is one of three aeroplanes exhibited outdoors at the National Museum of Flight (Scotland), which has created different conservation challenges over the years, as the aeroplane is subjected to a harsh and uncontrolled environment. Unfortunately, a plan to relocate the Comet indoors had to be postponed,...Marochini, Suncana ; Troalen, Lore

Abstract
Application of DESI–MS for dye analysis of historical textiles
One key issue in the dye analysis field is the need to sample culturally significant objects. This issue is amplified when working with more fragile objects, such as historical textiles, where sampling is often impossible without threatening the structural integrity of the object. To circumvent the impact of dye analysis,...Sandström, Edith ; Vettorazzo, Chiara ; Mackay, C Logan ; Troalen, Lore G ; Alison N, Hulme
