Hokkaido University researchers developed a new strategy for solid-state palladium-catalysed cross-coupling reactions using mechanochemistry, enabling efficient solvent-free synthesis of organic materials. Adding olefin facilitates a more efficient reaction, increasing conversion rates from less than 30% to 99%.
A new study published in ERJ Open Research directly compares new heated tobacco devices with vaping and traditional cigarettes, showing that all three are toxic to human lung cells. The study's findings suggest that these newer electronic nicotine delivery devices may not be a safer substitute for cigarette smoking.
A recent study predicts that climate change and rising sea levels will destroy the Sundarbans region, home to around 4,000 Bengal tigers, by 2070. The researchers used computer simulations to assess the future suitability of the area for tigers and their prey species.
Research finds less than a third of world's Key Biodiversity Areas have pristine night skies, while over half are under artificially bright skies. This study highlights the significant impact of light pollution on ecosystems, causing changes in species behavior and ecosystem cycles.
