Archaeologists analyzed trees engraved by the Indigenous Sámi of Arctic Europe, revealing the significance of these rare remnants of Sámi culture and the importance of preserving them from ongoing deforestation.
The changes in society and the phenomena surrounding us are becoming more unexpected and interconnected than ever before. This increasing complexity challenges strategic management, making it harder to predict trends and developments. According to a new study from the University of Vaasa, Finland, increased complexity demands new approaches to strategic management.
The international BIOCAL expedition, led by the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB), provided new evidence on the phenomenon of "atlantification" of the Arctic Ocean, a process related to climate change that involves the progressive invasion of Atlantic waters into the polar Arctic Ocean.
Forests with few tree species pose a considerably higher risk of being damaged, and the introduced lodgepole pine is especially vulnerable. This is the finding of a new study published in Ecosphere by researchers from Umeå University and the Swedish University of Agricultural Science in Uppsala. The results can be useful for preventing forest damage and financial losses related to the forest industry.
Ralstonia solanacearum is a soil-borne pathogen that devastates tomato and other Solanaceae crops globally. Traditional chemical controls have proven inadequate and environmentally damaging.
The human skin is home to a wide variety of bacteria. The composition of the community of bacteria—called the "skin microbiota"—has serious implications for skin health. A healthy balance between different species of bacteria on the skin often translates to healthy skin.
Quantitative disease resistance (QDR) is a complex but durable form of plant disease resistance that provides partial protection against a broad range of pathogens. Unlike qualitative resistance, driven by major resistance (R) genes, QDR is polygenic and manifests in various ways, such as delayed lesion development or reduced infection frequency.
Rice is a staple food crop for more than half the world's population, but most farmers don't grow high-yielding varieties because the seeds are too expensive. Researchers from the University of California's Davis and Berkeley campuses have identified a potential solution: activating two genes in rice egg cells that trigger their development into embryos without the need for fertilization, which would efficiently create high-yielding clonal strains of rice and other crops.
Noninvasive phenotyping has emerged as a vital tool in plant science, enabling the study of stress indicators without disrupting plant growth. While most studies have historically focused on analyzing stress responses in leaves, this novel research adopts a multi-organ view, assessing the dynamic interplay between leaves, stems, and roots when exposed to abiotic stress.
Normally found only in heavy metal bands or certain post-apocalyptic films, a "flame-throwing guitar" has now been spotted moving through space. Astronomers have captured movies of this extreme cosmic object using NASA's Chandra X-ray Observatory and Hubble Space Telescope.
