Tiny particles that seed clouds can form from trace gases over open sea — ScienceDaily

New results from an atmospheric study over the Eastern North Atlantic reveal that tiny aerosol particles that seed the formation of clouds can form out of next to nothingness over the open ocean. This “new particle formation” occurs when sunlight reacts with molecules of trace gases in the marine boundary layer, the atmosphere within about […]

Tiny particles that seed clouds can form from trace gases over open sea

Results from a study of clouds and aerosols conducted in the Azores revealed that new particles can seed the formation of clouds in the marine boundary layer—the atmosphere up to about a kilometer above Earth’s surface—even over the open ocean, where the concentration of precursor gases was expected to be low.

Credit: SPbU Scientists from Russia, Austria, and the USA have discovered virus-like particles in the bacterial symbionts of Bryozoa—a phylum of colonial aquatic invertebrates—filter-feeders dominating in many bottom ecosystems. The research project was planned and supervised by scientists from St Petersburg University. Some of the virus-like […]

Researchers publish review article on the physics of interacting particles

Scientific articles in the field of physics are mostly very short and deal with a very restricted topic. A remarkable exception to this is an article published recently by physicists from the Universities of Münster and […]

Experts develop new mechanism that can trap submicron particles in minutes

The researchers found salt acted similarly to a magnet. Credit: Loughborough University A spoonful of sugar may make the medicine go down, but a new Loughborough-led study suggests a dash of salt is key to progressing important medical areas such as drug delivery and biological sample analysis.

Scientists from the […]
