Summary: The study found that bark thickness, tree size and growth rate, as well as resin ducts, play important roles in trees' resistance to bark beetles. The black pine subspecies P. nigra subsp. salzmannii is more fire-resistant compared to the Scots pine, resulting in fewer attacks. Overall, tree size and resin duct characteristics determine the tree's resistance to bark beetles.

Summary: The use of birch tar is significant for understanding the capabilities of Neanderthals. Techniques for making birch tar in the European Middle Palaeolithic are still unknown. Recent experiments have suggested a groove-like structure method, which resulted in higher tar yields. However, further research using replicated experiments is needed to fully understand the implications for Palaeolithic tar making.

Summary: This study provides the earliest direct evidence of the specific use of birch bark tar in the production of ornaments through chemical and microscopic analyses. These ornaments, found in a public cemetery in southwest China, represent a unique cultural phenomenon among different ethnic groups and contribute to a better understanding of plant exploitation and cultural interrelationships in the past.

Summary: The plasticized film, made of polylactide and birch tar, was used in different concentrations for the purpose of obtaining antimicrobial properties. The film was characterized and its biodegradation process was studied. Different analysis techniques were employed to assess the enzymatic activity of microorganisms, biodegradation in compost, barrier properties, and structural changes of the film. The findings suggest that the addition of specific microorganism strains and bioaugmentation can enhance the biodegradation susceptibility and alter the physicochemical properties of the film. These films can have potential applications in the packaging industry and intentional biodegradation processes.

Summary: The study evaluated the antifungal potential of Pinus sylvestris bark against several plant pathogenic fungi and confirmed its in vitro efficacy. Trichoderma spp. isolated from the bark also showed antagonistic effects against the fungi. The study highlights the importance of environmentally friendly methods for controlling plant diseases caused by Botryosphaeriaceae.

Summary: The research showed that only trees that were both root-trenched and attacked by bark beetles depleted carbohydrates and died during the first year of attacks. Live trees contained higher carbohydrates than dying trees, but levels of diterpenes did not vary between the two groups. This suggests that reallocation of carbohydrates to diterpenes during early stages of beetle attacks is limited in drought-stricken trees, and combination of biotic and abiotic stress leads to tree death.

Summary: The study focused on using organic acids from biorefineries to reform pine and birch hydrolysate from waste wood, demonstrating that direct processing of the hydrolysates is feasible for close to full conversion. The best results were achieved with a tailored bimetallic Pd-Pt/sibunit catalyst in a temperature range of 175°C-225°C.

Summary: Wood bark is a major residue in the forest industry, used for producing process heat and energy. Extraction of birch bark via ultrasound can produce valuable substances, but also leads to an increase in ash content and a decrease in energy content.

Summary: This paper presents an atlas of micromorphological degradation of archaeological birch bark, analyzing 13 samples extracted from various archaeological objects and comparing them to a contemporary sample. The study identifies 13 morphological characteristics associated with degradation and provides LM and TEM images. The atlas offers a useful tool for conservator-restorers to connect macroscopic appearance to microscopic structure, especially in relation to factors such as color changes, loss of pliability, presence of delamination, and increased brittleness.

Summary: This study examines the use of plant resins, tars, and organic fossil substances in ancient societies, focusing on the Neolithic period in the North-West Mediterranean. It reveals insights into production systems, procurement strategies, and the transportation of materials such as birch bark tar over long distances. The research highlights the variability and complexity of adhesive production systems and supply networks at different spatial scales during the Neolithic era.

Summary: Gas chromatography was used to separate acyclic saturated hydrocarbon enantiomers, and the absolute stereochemical configuration was determined through the synthesis of single enantiomers. The study highlights the significance of chiral hydrocarbons and their potential use as biosignatures in geological and astrobiology studies. Additionally, the findings have implications for the search for life on Mars by the ESA's ExoMars rover in 2023.

Summary: The ability of ancient Egyptians to preserve human bodies through embalming has fascinated people. Through archaeological, philological, and organic residue analyses, this study sheds new light on the embalming practice in ancient Egypt. The analysis of ceramic vessels from a 26th Dynasty embalming workshop revealed the use of specific mixtures of oils, tars, and resins for embalming. The study also highlights the trade networks that provided ancient Egyptian embalmers with foreign substances needed for mummification.
