The measuring methods for diacetyl content in beer including EBC method, GC method and chemical radiation method were optimized and compared.

And the researchers hope the device may soon provide chemists or first responders to a chemical spill with a wearable detector, much like the badges worn to detect radiation.

Mutations can be induced by radiation, chemical treatment, foreign pathogens (e.g. viruses), or due to errors that occur during replication of the genome each time a cell divides.
