A newly discovered form of chemical intermediary in the atmosphere has the ability to remove pollutants in a way that leads to cloud-formation and could potentially help offset global warming.

The existence of these so-called Criegee biradicals, which are formed when ozone reacts with a certain class of organic compounds, was theorized over fifty years ago, but they have now been created and studied in the laboratory for the first time.

According to Science Daily, the discovery was made possible through the use of a third-generation synchrotron at the Lawrence Berkeley National Laboratory which produces an intense, tunable light that enables scientists to differentiate between molecules which contain the same atoms but arranged in different combinations.
