Alexandria Johnson does hard science on the most nebulous of subjects: clouds. As an atmospheric scientist and assistant professor of practice in Purdue University’s College of Science, she studies ...

Graduate students analyze cloud formation data with research scientist Jesse Anderson, using the Pi Cloud Chamber to study atmospheric processes. × Michigan Tech's Pi Cloud Chamber is giving ...

WEST LAFAYETTE, Ind. — Every cloud is lined, not with silver, but with science — at least from cloud expert Alexandria Johnson’s point of view. Clouds are ubiquitous. They are one of the most notable ...

As part of the international CLOUD project at the nuclear research centre CERN, researchers at PSI have identified so-called sesquiterpenes – gaseous hydrocarbons that are released by plants – as ...

When triggered by some external agent, shockwaves can propagate through molecular clouds of gas and dust to create pockets of dense material. At a certain limit, that dense gas and dust collapses and ...

Every year between September and December, Lubna Dada makes clouds. Dada, an atmospheric scientist, convenes with dozens of her colleagues to run experiments in a 7,000-gallon stainless steel chamber ...

A new experiment conducted at the world's largest particle physics laboratory, demonstrates the mechanism for how the gas-phase form of iodine -- known as iodic acid -- forms, and suggests it has a ...

Using 35 years of satellite data, researchers observed a consistent pattern for ice cloud formation stemming from desert dust in the atmosphere. The way clouds freeze is vital piece of the puzzle for ...
