Undergraduate students perceive e-cigarette secondhand emissions as harmful when labeled 'chemicals' or 'aerosols', but not 'vapor'. The study recommends accurately labeling e-cigarette emissions to build support for tobacco-free campus policies.
On average, four and a half people are killed annually in Australian coastal rescues, with victims often being male beachgoers trying to help minors. The study highlights the risks of bystander rescues and emphasizes the need for caution when intervening in water emergencies.
A research team has developed nanoscale copper wires with specially shaped surfaces to catalyze the conversion of carbon dioxide into ethylene, producing a conversion rate of over 70%. The new system is more efficient than previous designs and can run for extended periods without losing efficiency.
Researchers developed a point-of-care GFAP assay that delivers results in minutes, outperforming the current FDA-cleared assay. The assay's diagnostic performance was significantly better than that of the S100B biomarker, validating its utility as a diagnostic marker for CT-detected lesions.
Scientists at Cold Spring Harbor Laboratory discovered the intricate details of the Origin Recognition Complex (ORC), a crucial protein in human genome replication. ORC changes shape dramatically as it assembles around DNA, with parts twisting and pinching to interact with the molecule.
Permafrost erosion in Siberia's Lena Delta has increased by nearly 16 metres since the 1960s, with 15-20 metre annual losses reported. The thawing releases significant amounts of carbon and nitrogen, intensifying the greenhouse effect.
New research from Queen Mary University of London reveals that tortoise hatchlings are attracted to face-like shapes from birth. The study suggests this early behavior may have evolved for reasons other than parental care, as tortoises do not form social groups and typically ignore members of the same species in early life.
Scientific research predicts large increases in mercury concentrations in Yukon River fish and water under high carbon emissions scenarios. For the low-emissions scenario, mercury concentrations are expected to increase by only about 14%.
Scientists studied the Deepwater Horizon spill's environmental and public health impacts, learning about dispersant effectiveness, oil degradation and marine life harm. Dispersants' benefits include reducing coastal ecosystem damage, but their chemical effects on marine life remain a concern.
