Nicotine e-cigarettes are more effective in helping people quit smoking than many conventional methods such as nicotine gums and patches and quitting with behavioral support or no support at all, an updated Cochrane review finds.
A process called nucleation often initiates phase transitions such as condensation or freezing.
A UCLA-led study uses advanced 3D atomic imaging to revise a widely accepted, century-old theory describing how nucleation happens.
The findings deepen our understanding of a fundamental process in nature and could have implications for far-flung areas of science and industry, including the development of next-generation alloys.
Researchers found that wildfire smoke and rain, through relatively infrequent, can deliver disproportionally large amounts of nitrogen, phosphorus and potassium to ecosystems. Analyzing satellite smoke observations and national network rainfall data from 250 sites across 16 climate regions in 2014, 2020 and 2022, the study found a striking increase in smoke-rain days in 2022 compared with 2014, with regional hotspots shifted from year to year. The findings show wildfire emissions can be an important source of material deposited into ecosystems, but not necessarily in a way that benefits growth or productivity.
In Biointerphases, researchers seek to explore whether setulae — the nanoscopic hairs geckos have covering their body — may have a role in preventing water from escaping and keeping the lizards from drying out. The team created a simplified computational model of the gecko’s skin, complete with a row of setulae, and using fluid dynamics models, they simulated the flow of air across the skin. They found that the setulae, thanks to their precise arrangement, trap air between one another, sheltering the skin and retaining water.
