Shallow oval bowls used on the Baltic coast in the Mesolithic have been suggested as oil lamps, burning animal fat. Here researchers confirm the use of four coastal examples as lamps burning blubber—the fat of marine animals, while an inland example burned fat from terrestrial mammals or freshwater aquatics—perhaps eels. The authors use a combination of lipid biomarker and bulk and single-compound carbon isotope analysis to indicate the origin of the residues in these vessels.

Particle analysis by scanning electron microscopy with energy-dispersive x- ray analysis is one of the current methods used in crime laboratories to aid law enforcement in identifying individuals who have recently fired or handled a firearm. During the discharge of a firearm, the high pressure caused by the detonation of the cartridge materials forces a portion of the generated gases through leaks in the firing mechanism of the weapon. These gases contain residues of smokeless powder, primer mixture, and contributions from the projectile itself. The condensation of these hot gases form discrete, micrometer-sized particles, which can be collected, along with dry skin cells, salts, and other hand debris, from the hands of a shooter by a simple adhesive lift technique. The examination of the carbon-coated adhesive lifts consist of time consuming systematic searches for high contrast particles of spherical morphology with the characteristic elemental composition of antimony, barium and lead. A detailed list of the elemental compositions which match the criteria for gunshot residue are discussed in the Aerospace report.

Background: This study reports an easy method of a veterinary drug investigation in raw milk, based on QuECHERS extraction followed by RP-HPLC-UV analysis. Use of this benchtop system was motivated by its availability and moderate cost relatively to other sophisticated methods such as LC-MS which are more efficient. Methods: This developed method has been optimized and then after validation according to EU legislation, it demonstrated good linearity with R²>0.997, acceptable peak resolution within a short time (<9.5 min) and good recovery of the analyzed drugs (OXY, ALZ and IVR, respectively 87.08, 99.02 and 92.01 %). Additionally, we applied the method to the analysis of cow milk, collected in Nouakchott, capital of Mauritania. Results: The obtained results indicated a mixed level of drug use according to targeted molecules. In 42% of sampled farms, the anti-parasitics IVR and ALZ were detected whereas the antibiotic OXY was detected in 50%. Conclusion: This investigation shows that 17% of the sampled farms exceeded European standards for IVR drug.

The Later Prehistory of North-West Europe provides a unique, up-to-date, and easily accessible synthesis of the later prehistoric archaeology of north-west Europe, transcending political and language barriers that can hinder understanding. By surveying changes in social forms, landscape organization, monument types, and ritual practices over six millennia, the volume reassesses the prehistory of north-west Europe from the late Mesolithic to the end of the pre-Roman Iron Age. It explores how far common patterns of social development are apparent across north-west Europe, and whether there were periods when local differences were emphasized instead. In relation to this, it also examines changes through time in the main axes of contact between the various regions of continental Europe, Britain, and Ireland. Key to the volume's broad scope is its focus on the vast mass of new evidence provided by recent development-led excavations. The authors collate data that has been gathered on thousands of sites across Britain, Ireland, northern France, the Low Countries, western Germany, and Denmark, using sources including unpublished 'grey literature' reports. The results challenge many aspects of previous narratives of later prehistory, allowing the volume to present a distinctively fresh perspective.
