Rethinking indoor air chemistry

People typically spend 90% of their lives inside, at home, at work, or in transport. Within these enclosed spaces, occupants are exposed to a multitude of chemicals from various sources, including outdoor pollutants penetrating ...

Help NASA scientists find clouds on Mars

NASA scientists hope to solve a fundamental mystery about Mars' atmosphere, and you can help. They've organized a project called Cloudspotting on Mars that invites the public to identify Martian clouds using the citizen science ...

Air lasing: A new tool for atmospheric detection

Ultrafast laser technologies provide new strategies for remote sensing of atmospheric pollutants and hazardous biochemical agents due to their unique advantages of high peak power, short pulse duration and broad spectral ...

First-time direct proof of chemical reactions in particulates

Researchers at the Paul Scherrer Institute PSI have developed a new method to analyse particulate matter more precisely than ever before. Using it, they disproved an established doctrine: that molecules in aerosols undergo ...

A fundamental shortcoming in air pollution models

Researchers from the University of Copenhagen have discovered a surprising phenomenon in a process by which certain gas molecules produce harmful particles. The impact of this phenomenon is likely to increase in urban areas ...

Breaking waves propel ancient molecules into the air

A discovery that helps explain how organic matter produced by life thousands of years ago is ultimately removed from the sea has been published in Science Advances by Steven Beaupré of Stony Brook University's School of ...
