The importance of complex networks of heterotypic interactions between multiple distinct cell types (both malignant and normal) and regulatory circuits has now become widely recognized.
Maritime litter is among the most urgent global pollution issues. Marine scientist Nikoleta Bellou and her team at Helmholtz-Zentrum Hereon have published an overview study of solutions for prevention, monitoring, and removal in the renowned scientifically journal Nature Sustainability. They found that reducing ocean pollution requires more support, integration, and creative political decisiveness.
Plant species with thick and dense roots are more likely to occur in warm climates, while species with thin and low density roots are more likely to occur in cold climates -- a classic trade-off. By contrast, forest species with large-diameter roots and high root tissue density were more commonly associated with dry climates, but species with the opposite trait values were not associated with wet climates. Instead, a diversity of root traits occurred in warm or wet climates.
Black people have a higher risk of colorectal cancer than white people, but this risk is likely not due to genetics. Data from a recent study by researchers from the US Department of Veterans Affairs, Regenstrief Institute and Indiana University School of Medicine adds more data to the existing evidence.
Climate change exerts great pressure for change on species and biodiversity. A recent study conducted by the University of Helsinki and the Finnish Environment Institute indicates that the few moth and butterfly species (Lepidoptera) capable of adjusting to a changing climate by advancing their flight period and moving further north have fared the best in Finland. In contrast, roughly 40% of Lepidoptera species have not been able to respond in either way, seeing their populations decline.
Researchers from Skoltech have designed and conducted experiments measuring gas permeability under various conditions for ice-containing sediments mimicking permafrost. Their results can be useful both in tracing methane emission in high latitudes and in modeling and testing techniques for gas production from Arctic reservoirs. The study also showed that the dissociation of gas hydrates can lead to permeability increase. This, in turn, will lead to methane emissions into the atmosphere, causing a variety of environmental and technological impacts.
Global ecosystem restoration efforts are often measured by billions of trees planted or square kilometers of land restored. But there is a critical void in the agenda: the social and political dimensions that make restoration a success.
Soot particles from oil and wood heating systems as well as road traffic can pollute the air in Europe on a much larger scale than previously assumed. The evaluation of the sources during a measuring campaign in Germany showed that about half of the soot particles came from the surrounding area and the other half from long distances. This underlines the need to further reduce emissions of soot that is harmful to health and climate.
Fraud is going uninvestigated by police who are "hiding behind the veil" of the Action Fraud national crime reporting agency.
The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) and the Intergovernmental Panel on Climate Change (IPCC) launch a peer-reviewed report based on a 4-day virtual workshop on addressing the biodiversity and climate crises together involving 50 jointly-selected international experts.
